Ingredients You’ll Need

Lentil and vegetable filling

• 1 cup dry brown or green lentils, rinsed
  • Brown or green hold their shape best; avoid red lentils since they turn mushy.

• 2 tablespoons olive oil
• 1 medium yellow onion, diced
• 2 medium carrots, diced
• 2 celery stalks, diced
• 3 cups peeled and cubed butternut squash (about 1 small squash)
  • Frozen butternut squash works great and saves time; no need to thaw fully.
• 3 cloves garlic, minced
• 1 tablespoon tomato paste
  • Squeeze tube tomato paste helps with easy measuring and storage.
• 1 teaspoon dried thyme
• 1 teaspoon dried rosemary, crushed between your fingers

Crust options

Pick one crust route based on your time and energy level.

Tips & Tricks

• Rinse lentils under cool water and pick out any tiny stones before cooking.
• Use pre cut or frozen butternut squash to cut prep time in half.
• Keep the lentils slightly firm; they continue to cook in the oven.
• Taste the filling before baking and adjust salt, pepper, and acid with a splash of vinegar.
• Vent the crust with a few slits so steam escapes and the top stays crisp.
• Place the baking dish on a sheet pan to catch any bubbly overflow.
• Let the pot pie rest 10 to 15 minutes after baking so the filling thickens.
• Use plant milk and an oil or vegan butter based crust to keep the lentil pot pie with butternut squash fully vegan.

How to Make Lentil Pot Pie with Butternut Squash

Cook the lentils

1. Add the rinsed lentils and vegetable broth to a medium saucepan.
2. Bring the mixture to a boil over medium high heat, then lower the heat to a gentle simmer.
3. Cook the lentils for 18 to 22 minutes until they feel tender but still hold their shape.
4. Drain any extra liquid and set the lentils aside while you start the vegetables.

Build the vegetable base

1. Heat the olive oil in a large oven safe skillet over medium heat.
2. Add the onion, carrots, and celery, then stir and cook for 6 to 8 minutes until the vegetables soften and the onion turns translucent.
3. Stir in the butternut squash cubes and cook for 5 minutes, so the edges start to brown.
4. Add the garlic and cook for 30 seconds until it smells fragrant.

Season and thicken the gravy

1. Stir in the tomato paste, thyme, rosemary, smoked paprika, and bay leaf.
2. Cook the mixture for 1 to 2 minutes so the tomato paste darkens slightly and the herbs wake up.
3. Sprinkle the flour over the vegetables and stir until the flour coats everything evenly.
4. Pour in the milk slowly while you stir, so the flour blends and no lumps form.

Finish the filling

1. Add the cooked lentils to the skillet and stir them into the creamy vegetable mixture.
2. Pour in the soy sauce, balsamic vinegar, and Dijon mustard, then stir again.
3. Add the frozen peas and cook for 3 to 5 minutes until the filling bubbles and thickens to a stew like texture.
4. Taste and season with salt and pepper until the lentil pot pie with butternut squash filling tastes rich and balanced.

Prepare the crust

1. Preheat your oven to 400°F while the filling simmers.
2. If you use puff pastry or pie crust, roll it out on a lightly floured surface so it fits your skillet or baking dish.
3. If you use the biscuit topping, whisk the flour, baking powder, baking soda, and salt in a bowl, then cut in the cold butter until the mixture looks like coarse crumbs.
4. Stir in the buttermilk just until the dough comes together and avoid overmixing.

Assemble the pot pie

1. Remove the bay leaf from the filling and smooth the top with your spoon.
2. If your skillet cannot go in the oven, transfer the filling to a greased 9×9 baking dish.
3. Lay the puff pastry or pie crust over the hot filling and tuck the edges down the sides, or drop biscuit dough in small mounds across the top.
4. Cut a few small slits in a solid crust so steam can escape.

Bake to golden perfection

1. Brush the crust with egg wash or milk so it browns nicely.
2. Place the skillet or baking dish on a sheet pan to catch drips.
3. Bake the lentil pot pie with butternut squash for 25 to 30 minutes until the crust turns deep golden and the filling bubbles around the edges.
4. Let the pot pie rest for 10 to 15 minutes, then scoop generous portions and serve.

What to Serve with Lentil Pot Pie with Butternut Squash

Serve lentil pot pie with butternut squash with a crisp green salad tossed in a simple lemony vinaigrette to cut through the richness. Steamed green beans, roasted broccoli, or sautéed kale pair nicely and add color to the plate. A side of applesauce or roasted apples brings a sweet note that matches the butternut squash. Offer sparkling water with citrus slices or a mug of herbal tea to keep the meal cozy and family friendly.

Storage Options

• Cool leftovers to room temperature, then cover the dish or transfer portions to airtight containers and refrigerate for up to 4 days.
• Freeze individual portions in freezer safe containers for up to 2 months for easy lunches.
• Reheat in a 350°F oven for 20 to 25 minutes until hot, which keeps the crust crisp.
• Use the microwave for quick single servings, then pop the portion under the broiler for 1 to 2 minutes if you want to crisp the top again.
