A full dish of leftover enchiladas goes into a 350 F (177 C) oven, covered with foil, for 20 to 25 minutes. One or two do fine in a skillet or the microwave. Whichever you pick, you’re checking for the same thing at the end: 165 F (73.9 C) in the center, read on a food thermometer.
That 165 F figure doesn’t change for cheese-only enchiladas. The USDA FSIS safe minimum temperature chart (updated April 2025) puts leftovers and casseroles at that number, and FoodSafety.gov (reviewed November 2024) applies it to meatless casseroles too.
Published tests don’t crown a single winner, mostly because each cook was heating a different amount. Pantry and Larder went with the skillet for one enchilada. Ashcroft Family Table went with the oven for big batches.
What is the best way to reheat enchiladas?
Oven for a full pan, skillet for one or two. The microwave is the fastest option and also the weakest on texture.
Pantry and Larder tested four methods and picked the skillet for a single enchilada. Joy to the Food ranked the toaster oven first, and Ashcroft Family Table points to the conventional oven when there’s a lot of leftovers to heat. Read together, the verdicts split over portion size more than over quality.
| Method | Setting and time | Texture | Best for |
|---|---|---|---|
| Oven | 350 F, 20 to 25 minutes, covered | Even heat, soft tortillas, set cheese | A full dish |
| Skillet | Medium-high, splash of water, lid on, about 2 minutes | Firm bottom, no soggy tortillas | Single servings |
| Toaster oven | 300 to 350 F, 5 to 10 minutes | Close to the oven result | Small batches |
| Air fryer | 350 F, 3 to 12 minutes | Crisp edges, drier filling | One or two enchiladas |
| Microwave | High, about 1.5 minutes per enchilada | Soft, often soggy | Speed over texture |
If you’re heating a whole dish or several enchiladas, use the oven and keep it covered. For one or two with no rush, the skillet is the better call. The air fryer gives you crisp edges, though the filling comes out drier. And with a single enchilada and two minutes to spare, the microwave works as long as you can live with softer tortillas.
Whichever one wins, the finish line is 165 F in the center.
Safe internal temperature for reheated enchiladas
Aim for 165 F (73.9 C) at the center, measured with a food thermometer. The USDA FSIS safe minimum temperature chart (last updated April 2025) lists leftovers and casseroles at that number, and FoodSafety.gov applies it to meatless casseroles too, so cheese-only enchiladas follow the same rule as beef or chicken.
Sauces, soups and gravies reheated on their own should reach a rolling boil instead (USDA FSIS). FSIS also says to cover leftovers while they reheat, which holds moisture and heats the food all the way through. If you’re using a microwave and the manufacturer gives no standing time, let the food stand at least 2 minutes.
Probe the center of the thickest enchilada first, then a couple of spots toward the edges of the dish. The middle of a packed pan heats last.
Extra enchilada sauce follows the same rule. Bring it to a rolling boil on the stove before it goes over the enchiladas.
Steam and bubbling cheese prove nothing. FSIS tells consumers to verify with a thermometer every time.
How to reheat enchiladas in the oven
Heat the oven to 350 F (177 C), cover the dish loosely with foil, and bake for 20 to 25 minutes. Ashcroft Family Table, The Yummy Bowl and Platter Talk (2024) all land on that window for a full dish.
Cooking in Celsius, or on a fan oven that runs hot? You can convert the 350 F setting before you start.
- Preheat the oven to 350 F (177 C).
- Spoon a little warm enchilada sauce around the edges if the dish looks dry.
- Cover the dish loosely with foil.
- Bake 20 to 25 minutes for a full dish, or about 10 minutes for one or two enchiladas on a lined tray (Joy to the Food).
- Uncover for the last 5 minutes if the cheese needs color.
- Probe the center for 165 F, then let the dish sit a minute before serving.
If you’re short on time, microwave them first. Pantry and Larder suggests 15 to 30 seconds in the microwave for refrigerated enchiladas (2 minutes at 50% power for frozen ones) before the oven, and The Yummy Bowl advises about 1 minute, which it says trims 5 to 10 minutes off the oven time.
Glass dishes need some care. Iowa State University Extension (2019) says to heat glassware gradually in a preheated oven and avoid temperature extremes, and it notes that modern Pyrex is less thermal shock resistant than older versions.
A cold glass dish going straight into a hot oven is the move to avoid. Slide the enchiladas onto a metal tray, or let the glass warm up while the oven preheats.
For single servings, The Yummy Bowl preheats an empty metal tray and sets the enchiladas on it, instead of reheating them in the cold dish they were stored in.
Sometimes the edges dry out while the center stays cold. Pantry and Larder’s fix (written for frozen enchiladas) is a hotter oven, 400 F (about 200 C), when they are not warm yet.
The 10-minute and 20-to-25-minute times above both come from published guides, and portion size explains the gap. A lone enchilada on a tray heats far faster than a packed 9×13 dish, so trust the thermometer over the timer.
Microwave, skillet, air fryer and toaster oven methods
The skillet gives the best texture, the microwave is the quick option, the air fryer crisps edges, and a toaster oven handles small batches. None of them is built for a full dish.
Microwave
It’s fast and forgiving, and it’s also the method most likely to leave soft tortillas.
On high, plan on about 1.5 minutes for a whole enchilada and 1 minute for half (Joy to the Food). Use a microwave-safe lid or wrap with a vent so steam escapes while moisture stays in (FSIS). The Yummy Bowl pokes small holes in the enchiladas or cuts them smaller to let steam out. Turn the dish midway, because FSIS warns that microwaves cook unevenly and leave cold spots where bacteria survive. Then let the plate stand before the thermometer goes in.
Pantry and Larder’s testers still marked the microwave down for soggy tortillas.
Skillet
Pantry and Larder named the skillet the best method for a single enchilada, and The Yummy Bowl calls it the best way to keep texture and flavor.
Use medium-high heat with a little oil, add a splash of water, put the lid on, and give it about 2 minutes of steam (Ashcroft Family Table). The tortillas don’t go soggy.
The downside is capacity. It handles only a few enchiladas per pan (Ashcroft Family Table fits up to four), there’s little room to add sauce, and the bottom can burn before the center is hot (Platter Talk, 2024).
Pick it for a solo lunch. Skip it for a family dinner.
Air fryer
Published air fryer times for enchiladas run from 3 to 4 minutes at 350 F (Ashcroft Family Table, The Yummy Bowl) to 8 to 10 minutes (Fork To Spoon) and 10 to 12 minutes (Thyme and Joy).
Recipes From A Pantry points out that basket load and portion size drive that spread, and starting temperature plays a part too. Joy to the Food runs 375 F in a baking dish.
Preheat to 350 F and work in a single layer. Line the basket with parchment when the sauce is heavy, and cover loosely with foil to hold moisture.
If the dish was written for a conventional oven, you can convert the oven setting for your air fryer instead of guessing.
The air fryer does tend to dry out a meat filling a bit, according to The Yummy Bowl.
Toaster oven
A toaster oven works like a small oven, and Ashcroft Family Table recommends it for smaller batches.
Settings split. Ashcroft Family Table uses 300 F for 5 to 7 minutes with the enchiladas on a foil-lined rack, while Joy to the Food, whose testers ranked it the most effective method, bakes one or two enchiladas at 350 F for about 10 minutes.
Keeping reheated enchiladas from going soggy or dry
Reheated enchiladas turn soggy when steam and sauce sit against the tortilla, and they dry out when heat outruns moisture. The tortilla and the sauce volume decide most of it.
Soggy ones usually have too much sauce. Tasting Table notes that tortillas arrive already sauced, so only a little goes on top, and Yahoo Lifestyle says excess sauce releases steam in the oven and softens the tortillas. Check the tortilla first, too, because corn absorbs less liquid than flour (Chowhound).
Dry ones need moisture back. Add a splash of water or chicken broth before covering with parchment or a lid (Texas Real Food), and in the microwave, add some liquid to the dish if needed (FSIS). Very Veganish found that steam from a damp paper towel works on tortillas when moisture and heat go together.
Added liquid fixes dry enchiladas and makes soggy ones worse, so work out which problem you have before pouring anything.
Prevention starts before the fridge, and a guide to stopping enchiladas from turning soggy covers the rolling and saucing steps.
Chowhound adds that a quick fry before rolling forms a light barrier against sauce. Food52 readers split on flour tortillas: some call them soggy but tasty, others rule them out.
For the next batch, the tortillas that hold up best under sauce make reheating easier.
Reheating frozen enchiladas: thaw first or not?
You can thaw first or skip it, and neither is a safety problem. USDA FSIS says frozen leftovers can be reheated in a saucepan, microwave or oven without thawing, though it takes longer.
The real split is texture. Pantry and Larder reheats straight from frozen because defrosting turns enchiladas very soggy, while The Yummy Bowl thaws overnight in the fridge, and Texas Real Food warns that heating from frozen can leave the dish unevenly hot.
| Starting state and oven | Covered | Uncovered | Source |
|---|---|---|---|
| Frozen, 350 F | 30 minutes | 20 minutes | Good Life Eats |
| Frozen, 350 F | 35 to 40 minutes | 10 minutes | Joy to the Food |
| Frozen, 375 F | 30 to 40 minutes | 10 to 15 minutes | Pantry and Larder |
| Thawed, 350 F | 20 minutes | 5 to 10 minutes | Good Life Eats |
Put the three frozen tests side by side and total oven time lands between 40 and 55 minutes, against 25 to 30 minutes for thawed enchiladas.
Joy to the Food heats one frozen enchilada in the microwave for 3 1/2 to 4 minutes. It doesn’t recommend the air fryer from frozen, since the released moisture stops the basket from crisping.
Good Life Eats says to remove the plastic wrap and foil layers before baking. How those layers go on in the first place is covered in a guide to freezing enchiladas.
For thawing, FSIS allows the refrigerator or the microwave, and cold water works too if the enchiladas sit in a leak-proof bag and you change the water every 30 minutes.
Cold-water and microwave thawing lead straight into reheating, with no waiting in between. FSIS counts microwave thawing as safe, but Good Life Eats advises against it for enchiladas because the cheese and tortillas dry out or turn rubbery.
Safe and good are different questions. Appliance-by-appliance detail sits in a dedicated guide to reheating frozen enchiladas.
When reheating enchiladas is not safe
Throw out enchiladas that sat out longer than 2 hours (1 hour above 90 F) or are past the fridge window. USDA FSIS applies that rule to all perishable food, casseroles included, and reheating rescues neither case. Anything that can’t be heated through is out too.
FSIS gives 3 to 4 days in the refrigerator at 40 F or below. In the freezer at 0 F, 3 to 4 months is the best-quality window, though frozen food stays safe indefinitely.
Shallow, covered containers cool leftovers fastest, which is the method in a guide to storing leftover enchiladas.
Freezer numbers disagree across sources. The FSIS leftovers guidance and a CBS Miami report quoting a USDA expert give about 3 to 4 months, while the FSIS and FoodSafety.gov cold storage chart gives 2 to 3 months for cooked meat and meat casseroles and 4 to 6 months for cooked poultry casseroles.
The spread follows the filling. Chicken enchiladas get the longer window, beef the shorter one.
Bacteria multiply rapidly between 40 and 140 F, and FSIS says merely keeping food warm inside that range is not safe. Slow cookers and chafing dishes are on its not-recommended list for reheating, for the same reason.
FSIS also sets a floor of 325 F for reheating meat and poultry in the oven. Ashcroft Family Table’s 300 F toaster oven setting sits below it, so run that method at 325 F or higher for meat- or chicken-filled enchiladas.
The smell test fails here. Mayo Clinic notes that bacteria typically do not change the look, smell or taste of food.
For other dishes sharing the same shelf, a quick lookup of how long leftovers last in the fridge saves guessing.
Sources disagree on how many times enchiladas can be reheated. USDA FSIS, as quoted by The Takeout, says reheated leftovers stay safe for another full refrigerator window, so there’s no fixed limit, but quality drops each time and you should reheat only the amount you need. Healthline and the Windsor-Essex County Health Unit both advise against reheating leftovers more than once.
Portion first, then heat. Pull out what one meal needs and leave the rest cold, and the disagreement stops mattering.
Reheating Enchiladas FAQ
Do enchiladas taste better the next day?
Yes, for flavor. Joy to the Food notes that enchiladas absorb more flavor from the sauce as they sit.
The same soaking softens the tortillas, so the reheating method decides whether the second day wins on texture too.
Do sour cream or cheese-only enchiladas reheat differently?
A little. Cooking Chew says sour cream enchiladas need extra moisture and a cover to soften the sauce back up, and Platter Talk warns that cheese enchiladas turn soggy more easily.
Check the center with a food thermometer either way.
Can you put foil in the microwave?
No. Foil belongs in the oven, where it holds moisture over a full dish.
In the microwave, FSIS recommends a microwave-safe glass or ceramic dish with a vented lid or wrap.
Should sour cream, avocado and cilantro go on before or after reheating?
After. Platter Talk finishes air fryer enchiladas with sour cream once they come out of the basket, and fresh toppings follow the same order.
Sauce and cheese go on before reheating, and the cold toppings wait for the plate.
Can restaurant enchiladas be reheated the same way as homemade ones?
Yes, with one timing check. FSIS treats restaurant leftovers like any other, so the 2-hour clock runs from when the plate was served, not from when it reached your fridge.
Past that point, discard them.
Portioning a Batch So Reheating Enchiladas Stays Easy
Reheating enchiladas goes fastest when the batch is split into single servings before it is chilled. A lone portion on a tray needs about 10 minutes in the oven, against 20 to 25 for a full dish, and it is heated only once.
Mayo Clinic advises freezing leftovers right away when they will not be eaten within 4 days. That puts the fridge-or-freezer decision on cooking night, not on day three.
Divide the batch into shallow, single-serving containers, freeze whatever the fridge window won’t cover, and write the date on each one.
Shallow containers cool leftovers faster, so portioning has to happen first. How many portions go into the freezer depends on what’s left after that.
The cost is more containers to wash and more freezer space than one foil pan takes.
