Turn the Instant Pot to Saute and let heat until hot.
Add in ground beef or ground sausage. Begin to brown and break up meat into smaller bites.
Add in kosher salt, 1 teaspoon Italian Seasoning, minced garlic, and diced onion. Saute for 3-5 minutes or until meat is no longer pink.
Once meat is browned, remove from pressure cooker using a slotted spoon. Turn Instant Pot off.
Pour in 1 1/2 cups of water into the Instant Pot Inner Pan and Scrape up any browned bits of meat with a spoon or spatula.
Add in trivet to the Instant Pot right over the water.
Mix together the ricotta cheese with an egg, 1 teaspoon Italian Seasoning, 1/2 teaspoon garlic powder and grated Parmesan cheese.
Layer the Lasagna
In a 7 inch by 3 inch Spring Form Pan or 7 by 3 inch oven safe cake pan, layer the ingredients for the lasagna.
Start with a thin layer of marinara sauce.
Break up oven ready lasagna noodles to fit to cover the bottom of the baking pan.
Top with half the ricotta cheese mixture. Sprinkle with half the meat and onion mixture.
Cover the meat mixture with marinara sauce and then sprinkle with light layer of mozzarella cheese.
Add another layer of lasagna noodles, breaking to fit in a single layer over the marinara sauce.
Top with remaining ricotta cheese mixture. Sprinkle with remaining meat mixture. Top with another layer of marinara sauce and then sprinkle with a light layer of mozzarella cheese. Add the final layer of lasagna noodles, breaking to fit again.
Top with a generous layer or tomato sauce. Sprinkle generously with shredded Mozzarella Cheese.
Bake the Lasagna in Pressure Cooker
Place the lasagna pan on a tin foil “sling” to help lower and lift lasagna out of Instant Pot.
Place lasagna on trivet inside pressure cooker.
Place lid on lasagna and turn vent knob to “seal.”
Set to high pressure for 22 minutes.
Let pressure release for 10 minutes and then do a quick release for any remaining pressure.
If you would prefer a browned top to your lasagna, remove lasagna from the Instant Pot and place on a cookie sheet. Place lasagna under broiler for 3-6 minutes, watching carefully, as to not burn.
Let lasagna sit for 10 minutes before serving.
I use my homemade tomato sauce, but any quality jarred marinara or pasta sauce will work for this Lasagna recipe.
Ground beef, pork, or Italian sausage are all great options for this Lasagna recipe.
If you would prefer a Meatless Instant Pot Lasagna, just omit the meat.
If you are worried about condensation forming on the top of your lasagna, loosely cover with foil and add 5 minutes to cook time. This will prevent any condensation forming on the cheese layer. If you skip that step, just lightly dab off any moisture that occurs and then broil to perfection!
