9x13-inch baking dishPreheat the oven to 400°F; rinse the lentils, slice the mushrooms, dice the onion and carrots, and cut the potatoes into even 1-inch pieces.
Keep fingers tucked away from the blade while slicing mushrooms, dicing vegetables, and cutting potatoes.
Boil the potatoes until fork-tender, about 12–15 minutes, then drain and reserve the cooking water needed for mashing. Cover potatoes with water before bringing to a boil. Start the filling in a separate wide, deep skillet of at least 4 quarts while they cook.
Drain the hot potatoes carefully to avoid steam burns and splashes from boiling water.
Mash the potatoes with two-thirds of the oil, one-third of the salt and half the pepper until fluffy and spreadable. Add reserved cooking water as needed.
Cook the onion, carrots and mushrooms in the remaining oil until mushrooms brown and reduce, about 8–10 minutes. Use medium heat and half the remaining salt.
Keep the skillet handle turned inward on the stovetop to prevent bumps and spills.
Simmer the lentils with broth, thyme, paprika, remaining salt and pepper until tender and saucy, starting to check after 28–32 minutes. Leave the skillet uncovered.
Cook the peas fully according to the package, including standing time, before stirring into the hot lentil filling. Use the specified pan or microwave-safe bowl. Mash a small portion of the filling to thicken it.
Spread the hot filling in a 9-by-13-inch dish of at least 3 quarts, then top evenly with mashed potatoes. Keep contents below the rim and roughen the potato surface with a spoon.
Bake for 20 to 25 minutes until the edges are bubbling and the potato topping is lightly golden; rest for 10 minutes before serving.
Use oven mitts when moving the hot baking dish in and out of the oven.
Let the casserole rest before serving so the hot filling thickens and is less likely to splash.
