Step 1

Spray oil in the bottom of a 7 inch cake pan or ramekin. Place some noodles in the bottom (break them to size). Spoon on marinara sauce on top of the noodles. Sprinkle the meatball slices or if you use the sausage, pre-cook it with the mushrooms and garlic and sprinkle them on.

Step 2

Scoop the ricotta cheese on top of the meat and finish the layer by covering it with mozzarella cheese. Follow this for a second layer. Finish the top with the remaining cheese.

Step 3

Pour the water in the bottom of the Instant Pot, place the trivet in the bottom, and set the lasagna on top of the trivet. Place the lid on the Instant Pot and select manual, pressure, high for 30 minutes. Let the pot finish the cycle and bleed off naturally. Let it sit for 10 minutes or more before serving.
