How to Cook Costco Enchiladas

The Kirkland Signature Enchilada Bake with Rotisserie Chicken sits in the Costco deli section, ready to heat.

It comes in an aluminum tray with a plastic lid. Just pop it in the oven.

The dish is loaded with shredded rotisserie chicken, corn tortillas, red enchilada sauce, pinto beans, black beans, roasted corn, bell peppers, and melted cheese. Costco makes this fresh in-store using their famous rotisserie chicken.

Each tray weighs about 4 pounds and feeds 6 to 9 people. Cooking time runs 50 to 60 minutes in a standard oven.

This guide covers three cooking methods: conventional oven, air fryer, and microwave. Times range from 8 minutes (microwave) to 60 minutes (oven), depending on your equipment and how much you’re heating.

Cooking Methods Comparison

Recommended Method: Conventional oven for the full tray. It heats evenly and gives you that bubbling cheese top without drying out the chicken.

Method 1: Conventional Oven (Recommended)

The oven method takes about an hour total but requires minimal effort. You get evenly heated enchiladas with properly melted cheese and tender chicken throughout. This works best when cooking the entire tray for a family dinner or party.

Step 1: How Do You Prepare the Enchilada Bake?

Remove the plastic lid from the aluminum tray. The enchiladas come ready to bake, so no additional prep is needed.

Instructions:

1. Take the tray out of the refrigerator
2. Remove the clear plastic lid completely
3. Cover the tray loosely with aluminum foil

Equipment: Aluminum foil, baking sheet

Step 2: What Temperature and Time Do You Use?

Preheat your oven to 400 degrees Fahrenheit. The enchiladas need 50 to 60 minutes of baking time to reach the proper internal temperature.

Instructions:

1. Preheat oven to 400F (200C)
2. Place foil-covered tray on a baking sheet
3. Position on center rack
4. Bake for 50-60 minutes

Temperature: 400F / 200C

Time: 50-60 minutes

Step 3: When Do You Remove the Foil?

Keep the foil on for most of the cooking time. If you want browned cheese on top, remove the foil during the last 5 minutes.

Instructions:

1. Leave foil on for the first 45-50 minutes
2. Remove foil at the 50-minute mark if cheese needs browning
3. Watch carefully to prevent the bell peppers from drying out

Checkpoint: At 50 minutes, check internal temperature

Step 4: How Do You Know When It’s Done?

The enchilada bake is done when the internal temperature reaches 165F. The cheese should be fully melted and bubbling around the edges.

Instructions:

1. Insert food thermometer into the center of the bake
2. Check that internal temp reads at least 165F
3. Look for bubbling sauce and melted cheese
4. Let stand 5-10 minutes before serving

Target Temperature: 165F (74C) minimum

Visual Indicator: Bubbling cheese, steaming when cut, no cold spots in center

Method 2: Air Fryer

The air fryer works well for smaller portions or when you want faster results. You get crispy edges and bubbling cheese in about half the time of conventional oven baking. The catch is that most air fryers cannot fit the full tray.

Step 1: How Do You Prepare for Air Frying?

Transfer a portion of the enchilada bake to a heat-safe dish that fits your air fryer. Or wrap individual portions in foil.

Instructions:

1. Scoop desired portion into an oven-safe dish
2. For single servings, wrap loosely in foil
3. Preheat air fryer for 3-4 minutes

Equipment: Air fryer, heat-safe dish or aluminum foil

Step 2: What Temperature and Time Do You Use?

Set the air fryer to 360F. Cooking time varies based on portion size.

Instructions:

1. Set air fryer to 360F (182C)
2. Single portions: 12-14 minutes
3. 2-3 servings: 15-18 minutes
4. Large portions (oven-style air fryer): 20-25 minutes

Temperature: 360F / 182C

Time: 12-25 minutes depending on portion size

Step 3: When Do You Check Progress?

Check at the 10-minute mark for single portions. For larger amounts, check around the halfway point.

Instructions:

1. Open air fryer at 10-minute mark
2. Check for even heating
3. Rotate dish if needed for even browning

Checkpoint: At 10 minutes for single portions, 12 minutes for larger amounts

Step 4: How Do You Know When It’s Done?

Look for bubbling cheese and crispy edges. The filling should be steaming hot throughout.

Instructions:

1. Check that cheese is fully melted and bubbling
2. Verify internal temperature reaches 165F
3. Let rest 2-3 minutes before eating

Target Temperature: 165F (74C)

Visual Indicator: Crispy edges, bubbling cheese, steam rising from filling

Method 3: Microwave

Microwave heating works best for single servings or reheating leftovers. The texture will be softer than oven or air fryer methods, but you save significant time.

Step 1: How Do You Prepare for Microwaving?

Transfer a single portion to a microwave-safe plate. Cover to trap steam and heat evenly.

Instructions:

1. Scoop one serving onto microwave-safe plate
2. Spread evenly for consistent heating
3. Cover with microwave-safe lid or damp paper towel

Equipment: Microwave-safe plate, microwave-safe cover

Step 2: What Power Level and Time Do You Use?

Use high power (100%) for fastest results. Heating time depends on portion size and microwave wattage.

Instructions:

1. Set microwave to HIGH (100% power)
2. Heat for 6-8 minutes for a full portion
3. Stop and stir at 3-4 minute mark

Power Level: HIGH (100%)

Time: 6-8 minutes for one serving

Step 3: When Do You Stir?

Stop the microwave halfway through to stir. This helps distribute heat evenly and prevents hot spots.

Instructions:

1. Pause at 3-4 minutes
2. Stir the enchilada filling
3. Re-cover and continue heating

Checkpoint: At 3-4 minute mark

Step 4: How Do You Know When It’s Done?

The filling should be steaming hot throughout with no cold spots. Check multiple areas with a thermometer if unsure.

Instructions:

1. Check that filling is steaming
2. Verify 165F internal temperature
3. Let stand 1-2 minutes before eating

Target Temperature: 165F (74C)

Visual Indicator: Steam rising throughout, cheese fully melted

• Add a dollop of guacamole and pico de gallo
• Serve over a bed of shredded lettuce
• Pair with lime tortilla chips on the side

Pairing Recommendations:

• Mexican rice or cilantro lime rice
• Refried beans
• Fresh garden salad
• Extra enchilada sauce or salsa on the side
• Hot sauce for those who like more heat

The enchilada bake is already packed with protein from the rotisserie chicken. If you want more veggies, a simple salad on the side balances the meal nicely.

Storage and Reheating

Leftover Storage

• Refrigerate within 2 hours of cooking
• Store in airtight container or cover tightly with plastic wrap
• Consume within 3-4 days
• The aluminum tray comes with a plastic lid that works well for storage

Reheating Instructions

• Microwave: 2-3 minutes at HIGH power per serving, stir halfway
• Oven: 350F for 15-20 minutes, covered with foil
• Air Fryer: 350F for 3-4 minutes
• Target Temperature: 165F throughout

Freezing

You can freeze the enchilada bake before or after cooking. Wrap tightly to prevent freezer burn. Thaw completely in the refrigerator before heating. If cooking from frozen, add approximately 45 minutes to the standard oven cooking time.

Troubleshooting Common Issues

Issue: Cheese not fully melted

Cause: Foil left on too long or oven temperature too low

Solution: Remove foil for last 5 minutes of baking. Make sure oven is fully preheated to 400F before inserting the tray.

Issue: Unevenly heated with cold spots

Cause: Oven not preheated, tray not centered, or insufficient cooking time

Solution: Always preheat oven completely. Place tray on center rack. Use a food thermometer to check multiple spots before serving.

Issue: Too spicy

Cause: Spice levels vary by Costco location since these are made fresh in-store

Solution: Serve with sour cream, guacamole, or extra cheese to cut the heat. Add a side of plain rice to balance the spiciness.

Issue: Dry or tough chicken

Cause: Overcooked or foil removed too early

Solution: Keep foil on for full cooking time. Remove from oven as soon as internal temperature reaches 165F. Do not exceed 60 minutes of baking.

Issue: Too saucy or runny

Cause: Normal variation, some trays have more sauce coverage

Solution: Let stand for 10 minutes after baking. The sauce will thicken as it cools slightly. Drain excess if needed before serving.

FAQ on How To Cook Costco Enchiladas

How Long Do You Cook Costco Enchiladas in the Oven?

Bake the Kirkland Signature Enchilada Bake for 50 to 60 minutes at 400F.

Most trays hit 165F internal temperature around the 50-minute mark. Check with a food thermometer to be sure the chicken is fully heated through.

What Temperature Should You Set the Oven To?

Preheat your conventional oven to 400 degrees Fahrenheit (200C).

This temperature works well for heating the rotisserie chicken filling evenly while melting the cheese on top. Lower temps take longer and may dry out the edges.

Can You Microwave Costco Enchiladas?

Yes. Transfer a single serving to a microwave-safe plate and cover it.

Heat on HIGH for 6 to 8 minutes, stirring halfway through. The texture will be softer than oven-baked, but it works great for quick weeknight dinners or reheating leftovers.

Can You Cook Costco Enchiladas in an Air Fryer?

Absolutely. Set your air fryer to 360F and cook portions for 12 to 25 minutes depending on size.

The full tray won’t fit most air fryers. Transfer smaller portions to a heat-safe dish instead. You get crispy edges and bubbling cheese faster than the oven method.

Do You Need to Thaw Costco Enchiladas Before Cooking?

The enchilada bake from the deli section is refrigerated, not frozen. No thawing needed.

If you froze it at home, thaw completely in the refrigerator first. Cooking from frozen adds about 45 minutes to oven time.

How Do You Know When Costco Enchiladas Are Done?

Check that the internal temperature reaches 165F in the center.

The cheese should be fully melted and bubbling. Steam should rise when you cut into the bake. No cold spots anywhere in the filling.

Can You Freeze Costco Enchilada Bake?

Yes. Wrap the tray tightly with plastic wrap and foil to prevent freezer burn.

Freeze for up to one month. Thaw overnight in the refrigerator before baking. The rotisserie chicken holds up well to freezing and reheating.

How Many Servings Are in a Costco Enchilada Tray?

Each tray weighs about 4 pounds and serves 6 to 9 people.

Serving size is roughly one cup (192g) per person. Add side dishes like Mexican rice or refried beans if you want to stretch it further for larger groups.

What’s the Best Way to Reheat Leftover Enchiladas?

Microwave individual portions for 2 to 3 minutes at HIGH power.

For better texture, use the oven at 350F for 15 to 20 minutes covered with foil. Air fryer works too: 350F for 3 to 4 minutes until hot throughout.

Should You Cover Costco Enchiladas When Baking?

Yes. Cover the tray loosely with aluminum foil before baking.

This traps moisture and prevents the bell peppers from drying out. Remove the foil during the last 5 minutes if you want browned, crispy cheese edges on top.

Conclusion

Learning how to cook Costco enchiladas takes about an hour from fridge to table. The Kirkland Signature enchilada bake works well for quick weeknight dinners or feeding a crowd.

Pick your method based on time and portion size. Oven for the full tray. Air fryer for crispy edges on smaller servings. Microwave when speed matters most.

Top with fresh guacamole, sour cream, or pico de gallo. Serve alongside Mexican rice or refried beans to round out the meal.

Store leftovers in the fridge for up to four days. Reheat to 165F and you’re good to go.
