Throwing dry lentils directly into a pressure cooker without accounting for age or variety often leads to uneven cooking results, where the outer skins split while the centers remain chalky. Soaking green lentils for fifteen minutes hydrates the outer seed coat just enough to promote uniform softening under high pressure. When substituting canned lentils for dry, reduce the manual high-pressure cooking time from eight minutes down to three minutes to prevent the legumes from turning into mush. The aromatic base of diced brown onion, carrots, and celery relies on the Instant Pot's sauté function to sweat out excess moisture before pressure is applied.
Cremini mushrooms and sun-dried tomatoes supply the deep, savory umami typically expected from meat-based fillings, substituting for traditional beef broth depth without requiring long simmering times. Deglazing the inner pot with one-quarter cup of red wine lifts the browned bits stuck to the bottom, which prevents the burn notification from triggering during the pressure cycle. Vegetable stock and soy sauce or wheat-free tamari balance the tomato acidity from both the tinned chopped tomatoes and the diced tinned variety. Bay leaves and a pinch of cinnamon add earthy undertones that round out the root vegetable and lentil mixture.
Potatoes can be boiled conventionally on the stovetop or steamed directly inside the cleaned Instant Pot for five minutes at high pressure, though retaining one-quarter cup of the starchy cooking liquid is mandatory for achieving a smooth puree. Incorporating almond milk, olive oil, garlic powder, and onion powder directly into the hot mashed potatoes creates a pliable topping that spreads easily over the lentil base. Swapping olive oil for butter or ghee alters the fat content and richness of the mash, while non-dairy milk alternatives like rice milk thin the puree consistency if added too generously.
Transferring the completed lentil filling to a casserole dish and blanketing it with the potato puree requires creating small indents or waves with a spoon to catch maximum heat. Baking the assembly at four hundred degrees Fahrenheit for ten to fifteen minutes crisps the exposed potato ridges near the top heating element. Letting the finished pie rest for several minutes after baking allows the lentil gravy to thicken and settle, preventing the portions from collapsing upon serving.
