step 1: Assemble the ravioli lasagna. First, grease the lasagna pan. Then pour in some marinara sauce, add a layer of meat or cheese ravioli, and sprinkle with part of the mozzarella and parmesan cheeses.
step 2: Pressure cook. Next, add water into the stainless steel base of the Instant Pot. Lower in the covered lasagna pan using the silicone sling. Seal the lid and do a manual pressure cook on high for 25 minutes
step 3: Brown the lasagna (optional). Use gloves to remove the foil from the pan. Either brown the ravioli lasagna using the Air Fryer, or broil for just a few minutes in the oven.
