Try this Spinach Mushroom Lasagna recipe
Making a layered pasta dish typically requires heating a full-size oven and monitoring multiple pots, but utilizing an electric pressure cooker changes that thermal requirement entirely. Fitting a lasagna into a multicooker demands a secondary vessel, specifically a 7-inch cake push pan or a similarly sized foil container that sits securely on a metal trivet above one cup of water. Frozen chopped spinach contains significant moisture that must be squeezed out thoroughly after the initial two-minute sauté phase, or the resulting sauce will dilute the ricotta and mozzarella layers. White mushrooms release additional liquid as they cook alongside onions and four minced garlic cloves, so draining these vegetables before assembly protects the structural integrity of the noodles. Breaking dried pasta sheets into smaller pieces allows them to fit inside the restricted diameter of the cake pan without overlapping excessively. Combining part-skim mozzarella and parmesan directly with low-fat ricotta creates a stable dairy filling that holds its shape under pressure without breaking down completely. Sealing the cake pan tightly with aluminum foil prevents condensation from dripping directly onto the top cheese layer during the twenty-minute high-pressure cooking cycle. Allowing a ten-minute natural pressure release lets the starches in the pasta finish setting before the lid is removed.
