Instant Pot Lasagna in a Pot-in-Pot Pan (Easy & Hearty Recipe)

There is nothing quite like a warm, bubbling slice of homemade lasagna to bring ultimate comfort to the dinner table. Traditional oven-baked lasagna, however, often demands hours of assembly, multiple dirty baking dishes, and an oven that heats up the entire kitchen.

Instant Pot Lasagna in a Pot-in-Pot Pan makes layered comfort food with less mess. Follow this easy recipe for cheesy, hearty slices every time.

By using the Pot-in-Pot (PIP) cooking technique with a non-toxic stainless steel insert pan, you can pressure cook tender pasta, savory marinara, and gooey melted cheese right inside your pressure cooker—without triggering the dreaded "Burn" error.

Why Use the Pot-in-Pot (PIP) Method for Lasagna in the Instant Pot?

If you have ever tried making a direct one pot lasagna recipe in your pressure cooker, you might have experienced thick pasta sauce sticking to the bottom of the liner, setting off the burn sensor before the noodles fully cook.

The Pot-in-Pot method solves this problem completely. By placing your ingredients inside a dedicated Ecozoi Stainless Steel Pot-in-Pot Insert Pan elevated on a wire trivet above a water bath, heat is transferred through steam pressure rather than direct element contact.

Benefits of PIP Lasagna Cooking:

• No Burn Errors: Steam surrounds the insert pan, ensuring thick sauces cook evenly without scorching.

• Non-Toxic & Sustainable: Ecozoi food-grade stainless steel contains zero toxic chemical coatings, Teflon, or aluminum leaching into your food.

• Perfect Portioning: Round stainless steel insert pans mold the lasagna into a neat, sliceable wheel ideal for family dinners.

• Easy Clean-Up: Less scrubbing required compared to deep, baked-on casserole dishes.

Equipment Needed

To prepare this instapot lasagna, you will need a few kitchen essentials:

1. Instant Pot / Electric Pressure Cooker: 6-quart or 8-quart capacity.

2. Ecozoi Stainless Steel Pot-in-Pot Insert Pan: Fits seamlessly inside 6qt and 8qt cookers.

3. Stainless Steel Trivet with Long Handles: For safely lowering and lifting the pan.

4. Ecozoi Bamboo Cutting Board: For chopping fresh garlic, herbs, and onions during prep. (Pro tip: Keep your prep surface pristine by following our guide on The Ultimate Guide to Bamboo Cutting Board Care: Oil, Clean & Store

5. Aluminum Foil or Silicone Lid: To cover the insert pan during pressure cooking.

Pot-in-Pot Instant Pot Lasagna Recipe

• Prep Time: 20 minutes

• Cook Time: 24 minutes

• Natural Pressure Release (NPR): 10 minutes

• Total Time: 54 minutes

• Servings: 4–6 portions

Ingredients

For the Meat Sauce:

• 1/2 lb (225g) lean ground beef or Italian sausage (or plant-based crumbles)

• 1/2 small yellow onion, finely diced

• 2 cloves garlic, minced

• 1.5 cups thick marinara or pasta sauce

• 1 tsp Italian seasoning

• Salt and black pepper to taste

For the Cheese Filling:

• 1 cup whole milk ricotta cheese (or cottage cheese)

• 1 large egg

• 1/4 cup grated Parmesan cheese

• 1 tbsp fresh parsley, chopped

• 1/4 tsp nutmeg (optional, for depth)

For the Layers:

• 6–7 regular lasagna noodles (oven-ready or regular, broken to fit the pan)

• 1.5 cups shredded mozzarella cheese, divided

• 1 cup water (added to the main Instant Pot liner pot)

Step-by-Step Instructions

Step 1: Prepare the Meat Sauce

Set your Instant Pot to Sauté mode. Add a splash of olive oil, diced onions, and minced garlic on your Ecozoi Bamboo Cutting Board. Brown the ground beef or sausage until fully cooked. Drain any excess fat. Stir in the marinara sauce and Italian seasoning, then turn off the Instant Pot. Transfer the sauce into a separate bowl and wipe down the inner pot.

Step 2: Mix the Cheese Layer

In a medium bowl, combine the ricotta cheese, egg, Parmesan, fresh parsley, salt, and pepper. Stir until smooth and creamy.

Step 3: Layer the Lasagna in the Pot-in-Pot Pan

Lightly grease the interior of your Ecozoi Pot-in-Pot Insert Pan with olive oil or butter.

1. Spread 2–3 tablespoons of meat sauce over the bottom of the pan.

2. Break the lasagna noodles into pieces that fit the shape of the round insert pan. Place a layer of noodles over the sauce.

3. Spread half of the ricotta cheese mixture over the noodles.

4. Sprinkle 1/3 cup of shredded mozzarella.

5. Repeat the layers: sauce, noodles, ricotta mixture, mozzarella, and top with the remaining meat sauce and mozzarella.

Step 4: Cover and Cook

1. Pour 1 cup of water into the main Instant Pot stainless steel inner cooking pot.

2. Cover the filled Ecozoi insert pan foil to prevent condensation from diluting the top layer.

3. Place the insert pan onto the trivet and carefully lower it into the Instant Pot.

4. Secure the Instant Pot lid and set the steam release valve to Sealing.

5. Select Manual / Pressure Cook on High Pressure for 24 minutes.

Step 5: Natural Release and Rest

Once the cooking cycle completes, allow a 10-minute Natural Pressure Release (NPR) before carefully releasing any remaining steam manually. Lift the insert pan out using the trivet handles.

Step 6: Optional Broil & Serve

Uncover the pan. If desired, sprinkle an extra layer of mozzarella and pop the pan under your oven broiler for 3–5 minutes until the top turns bubbly and golden brown. Let the lasagna rest for 10 minutes before slicing to ensure neat, firm layers!

Expert Tips to Prevent Watery Lasagna

One of the most common issues cooks face with lasagna in the instant pot is excess liquid accumulation. Follow these pro tips:

1. Use a Thick Sauce: Avoid thin, watery marinara. A rich, condensed pasta sauce yields firm slices.

2. Cover the Insert Pan: Covering the pot-in-pot pan prevents trapped steam condensation from pooling over the cheese layer.

3. Rest Before Slicing: Cutting into hot pressure cooker lasagna immediately will cause cheese and sauce to run. Rest for 10 to 15 minutes so the pasta absorbs remaining moisture.

FAQs

1. How long do you cook lasagna in an Instant Pot?

When using the Pot-in-Pot method, cook lasagna on High Pressure for 24 minutes, followed by a 10-minute natural pressure release. This ensures raw or oven-ready noodles soften completely while melted cheeses combine evenly.

2. How do I make lasagna in an Instant Pot?

You can easily make lasagna instant pot dishes by assembling sauce, ricotta, broken noodles, and mozzarella in a round stainless steel insert pan. Place the pan on a trivet over 1 cup of water inside the Instant Pot, cover, and pressure cook on high pressure.

3. How long does one pot lasagna take to cook?

A one pot lasagna recipe prepared in a pressure cooker takes approximately 24 minutes of pressure cooking time, plus about 10 minutes to build pressure and 10 minutes for natural pressure release totaling roughly 45 to 55 minutes overall.

4. Why is my Instant Pot lasagna watery?

Pressure cooker lasagna can turn watery due to steam condensation dripping into an uncovered pan, using overly thin pasta sauce, or failing to let the lasagna rest before slicing. Covering your insert pan tightly and letting the dish rest for 10–15 minutes solves this problem.

5. What are some common mistakes to avoid when making lasagna in pots?

• Forgetting water in the bottom pot: Always add at least 1 cup of water under the trivet.

• Overcrowding noodles: Overlapping dry noodles tightly can prevent steam from cooking the center layers evenly.

• Skipping the trivet: Placing the insert pan directly on the heating element causes uneven cooking and errors.

6. How to cook lasagna in a pressure cooker?

To cook instant pot lasagna recipes, use a elevated pot-in-pot insert system. Layer marinara sauce, broken noodles, ricotta mixture, and cheese inside a stainless insert, cover with foil, lower onto a trivet over water, and cook on High Pressure for 24 minutes.
