How to Cook Costco Ravioli Lasagna

The Kirkland Signature Ravioli Lasagna with Beef & Pork Bolognese Sauce is a refrigerated Italian comfort food sold at Costco warehouses.

It features layers of four cheese ravioli (ricotta, asiago, parmesan, romano) covered in a meaty bolognese sauce and topped with melted mozzarella and provolone cheese.

This is a ready-to-cook meal. Not frozen.

You’ll find it in the refrigerated deli area near rotisserie chickens and other premade meals like shepherd’s pie and Costco chicken alfredo.

Most people grab this for weeknight dinners when they want something filling without the prep work. One tray feeds 6-8 people depending on portion size.

This guide covers three cooking methods: conventional oven, convection oven, and air fryer. Total cook times range from 40 minutes to 70 minutes depending on which method you choose.

Cooking Methods Comparison

Recommended Method: Conventional oven at 400°F for even heating and the best cheese crust development on top.

Method 1: Conventional Oven (Recommended)

The standard oven method takes about 60-70 minutes total. You’ll get a bubbly, golden brown cheese topping with fully heated pasta throughout. This works best for the entire 3.3-pound tray.

Step 1: How Do You Prepare the Ravioli Lasagna?

Remove the clear plastic lid from the aluminum tray. Keep the lasagna in its original tray for baking.

Instructions:

1. Preheat your oven to 400°F
2. Place the tray on a baking sheet (catches drips)
3. Cover loosely with aluminum foil

Equipment: Baking sheet, aluminum foil, oven mitts

Quick tip: Spray the underside of your foil with cooking spray. This keeps the shredded cheese from sticking when you remove it later.

Step 2: What Temperature and Time Do You Use?

Bake at 400°F covered with foil for 50-60 minutes. Then remove foil and continue baking for 10 more minutes.

Instructions:

1. Place covered tray on center rack
2. Set timer for 50 minutes
3. Remove foil at 50-minute mark
4. Continue baking uncovered for 10 minutes

Temperature: 400°F

Time: 60-70 minutes total

Step 3: When Do You Remove the Foil?

Remove the aluminum foil after 50 minutes. This allows the mozzarella and provolone topping to brown and develop that golden crust.

Instructions:

1. Carefully lift foil away from tray at the 50-minute mark
2. Check that the marinara sauce is bubbling around edges
3. Return uncovered to oven

Checkpoint: At 50 minutes, edges should be bubbling. Cheese should be melted but not yet browned.

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

The ravioli lasagna is done when the internal temperature reaches 165°F and the cheese on top is golden brown with visible bubbling.

Instructions:

1. Insert food thermometer into center of dish
2. Verify internal temp is at least 165°F
3. Look for golden brown cheese crust on top
4. Let rest 5-10 minutes before serving

Target Temperature: 165°F minimum

Visual Indicator: Golden brown cheese, bubbling sauce, steaming when cut

The resting time matters. I learned this the hard way. If you cut into it immediately, the bolognese sauce runs everywhere. Give it 10 minutes and everything holds together much better.

Method 2: Convection Oven

Convection cooking cuts about 15-20 minutes off your total time. The circulating hot air browns the mozzarella topping more evenly. This method works well if you have a convection setting on your oven or a countertop convection oven.

Step 1: How Do You Prepare for Convection Baking?

Same prep as the conventional method. Remove plastic lid, keep in original tray, cover with foil.

Instructions:

1. Preheat convection oven to 350°F
2. Place tray on baking sheet
3. Cover with aluminum foil (spray underside first)

Equipment: Baking sheet, aluminum foil, food thermometer

Step 2: What Temperature and Time for Convection?

Lower temperature, shorter time. The fan circulates heat more efficiently.

Instructions:

1. Bake covered at 350°F for 40-45 minutes
2. Remove foil
3. Continue baking 10-15 minutes until browned

Temperature: 350°F

Time: 50-60 minutes total

Step 3: When Do You Check for Doneness?

Check around the 40-minute mark. Convection ovens vary in power.

Instructions:

1. Remove foil at 40 minutes
2. Check edge bubbling
3. Continue until cheese browns (10-15 more minutes)

Checkpoint: At 40 minutes, sauce should bubble at edges

Step 4: Final Temperature Check

Same target: 165°F internal temperature.

Instructions:

1. Test center with food thermometer
2. Confirm golden brown top
3. Rest 5-10 minutes

Target Temperature: 165°F

Visual Indicator: Crispy cheese edges, bubbly center, golden brown top

Method 3: Air Fryer

The air fryer works best for individual portions or smaller servings. Most air fryer baskets cannot fit the full tray. You can cut portions or transfer to an air fryer-safe dish.

This method gives you the crispiest cheese top but requires more attention.

Step 1: How Do You Prepare for Air Frying?

You will need to portion the lasagna or use an air fryer oven large enough for the tray. Remove all plastic before air frying.

Instructions:

1. Preheat air fryer to 350°F
2. Cut portions to fit your basket (if needed)
3. Place portions in air fryer-safe dish
4. Cover with foil initially

Equipment: Air fryer, oven-safe dish that fits, aluminum foil, food thermometer

Do not use any plastic film in the air fryer. Remove it completely.

Step 2: What Temperature and Time for Air Fryer?

Start covered, then remove foil for crisping.

Instructions:

1. Air fry covered at 350°F for 20-25 minutes
2. Remove foil
3. Continue at 350°F for 10-15 minutes

Temperature: 350°F

Time: 30-40 minutes total (for portions)

Step 3: When Do You Remove the Foil?

After the initial covered cooking, remove foil to let the cheese brown.

Instructions:

1. Check at 20-25 minutes
2. Remove foil carefully
3. Continue cooking until browned

Checkpoint: At 20 minutes, pasta should be hot, cheese melted

Step 4: How Do You Know When Air Fried Lasagna Is Done?

Same internal temperature target. The top will crisp faster than oven methods.

Instructions:

1. Check internal temp reaches 165°F
2. Top should be golden and crispy
3. Let rest 3-5 minutes

Target Temperature: 165°F

Visual Indicator: Crispy golden top, bubbling, hot center

Serving Suggestions

Portion Size: 6.6 oz per serving (8 servings per package). Realistically, most adults eat closer to 8 oz portions, giving you about 6 servings per tray.

Serving Ideas

• Top with freshly grated parmesan cheese and fresh basil
• Serve with a side of Caesar salad or mixed greens
• Add crusty Costco garlic bread for dipping in the bolognese sauce

Pairing Recommendations

• Green salad with Italian dressing
• Roasted Costco frozen vegetables like broccoli or zucchini
• Red wine (Chianti or Sangiovese pairs well with the beef and pork bolognese)

Storage and Reheating

Leftover Storage

• Refrigerate within 2 hours of cooking
• Store in airtight container or cover tray tightly with plastic wrap and foil
• Consume within 3-4 days
• Can freeze cooked leftovers for up to 2 months

Reheating Instructions

• Oven: 350°F for 20-25 minutes covered with foil, until heated through
• Microwave: 2-3 minutes per portion on HIGH, cover with paper towel
• Air Fryer: 350°F for 8-10 minutes
• Target Temperature: 165°F when reheating

The oven gives the best reheated texture. Microwave works but the pasta can get a bit softer. Add a splash of marinara sauce before reheating to keep it moist.

Troubleshooting Common Issues

Issue: Cheese stuck to aluminum foil

Cause: Foil pressed too tightly against cheese topping

Solution: Tent the foil loosely. Spray underside with cooking spray before covering.

Issue: Cold spot in the center

Cause: Not cooked long enough or oven temperature too low

Solution: Use food thermometer to verify 165°F. Add 5-10 minutes if needed. Make sure oven is properly preheated.

Issue: Sauce is runny when served

Cause: Did not rest long enough after baking

Solution: Let the ravioli lasagna rest 10 minutes before cutting. This allows the bolognese sauce to thicken and set.

Issue: Pasta is too firm

Cause: Undercooked or oven ran too hot and dried out the top before center cooked

Solution: Keep covered longer. Verify internal temperature reaches 165°F. The four cheese ravioli should be tender throughout.

Issue: Top is burnt but center is cold

Cause: Foil removed too early or oven temperature too high

Solution: Keep covered for full 50-60 minutes. Lower temperature by 25°F if your oven runs hot.

FAQ on How To Cook Costco Ravioli Lasagna

What temperature do you cook Costco ravioli lasagna?

Preheat your oven to 400°F for the conventional method.

For convection ovens, use 350°F instead. Air fryers also work at 350°F.

The higher temp in a regular oven helps the four cheese ravioli cook evenly while browning the mozzarella topping.

How long does Costco ravioli lasagna take to cook?

Plan for 60-70 minutes total in a conventional oven.

Cover with foil for 50 minutes, then uncover for the last 10-15 minutes. Convection ovens cut this to about 50-55 minutes.

Air fryer portions take 30-40 minutes.

Can you freeze Kirkland Signature ravioli lasagna?

Yes. This refrigerated meal freezes well for up to 2-3 months.

Wrap tightly in plastic wrap, then aluminum foil. When cooking from frozen, add 15-20 minutes to the bake time and keep covered longer.

Do you need to cover the ravioli lasagna when baking?

Absolutely. Cover with aluminum foil for most of the cooking time.

This traps steam and heats the bolognese sauce and pasta evenly. Remove the foil only for the final 10-15 minutes to brown the cheese layer on top.

Can you cook Costco ravioli lasagna in an air fryer?

Yes, but with limitations. Most air fryer baskets cannot fit the full tray.

Cut portions to fit, transfer to an air fryer-safe dish, and cook at 350°F for 30-40 minutes. Remove all plastic first.

How many servings are in Costco ravioli lasagna?

The package lists 8 servings at 6.6 oz each.
