Lentil Pot Pie with Butternut Squash tastes cozy and savory with a hint of sweetness from the squash and a flaky, golden crust on top. It suits busy weeknights or relaxed Sunday dinners and usually lands on the table in about an hour, start to finish. I first made a version of this on a cold Chicago night, and my family still talks about that bubbling skillet like it was a holiday.

Why Lentil Pot Pie with Butternut Squash Is Worth It

This pot pie tastes hearty and rich, even though it skips meat. Lentils bring protein and chew, while butternut squash adds creamy sweetness that balances the savory gravy.

The recipe uses simple pantry staples and a few fresh veggies, so you can pull it together without a specialty store run. A store bought crust or puff pastry keeps the process easy, and the filling works great for meal prep.

Ingredients You Need

Lentil and vegetable filling

1 cup brown or green lentils, rinsed
- Brown or green lentils hold shape best and give a nice bite. Avoid red lentils since they turn mushy.
3 cups low sodium vegetable broth
- Use your favorite brand; Better Than Bouillon works great and saves pantry space.
2 tablespoons olive oil or avocado 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 cubed squash works perfectly and saves time.
3 cloves garlic, minced
1 cup frozen peas
2 tablespoons tomato paste
2 tablespoons soy sauce or tamari
1 teaspoon dried thyme
1 teaspoon dried rosemary, crushed between your fingers
1 teaspoon smoked paprika
1 teaspoon kosher salt, more to taste
½ teaspoon black pepper
3 tablespoons all purpose flour
- Use a gluten free all purpose blend if needed.
1½ cups unsweetened non dairy milk or regular milk
- Oat milk or cashew milk give the creamiest texture without sweetness.

Crust and topping

1 sheet puff pastry, thawed
- Pepperidge Farm or any all butter puff pastry works well; check the label for vegan needs.
1 egg, beaten with 1 tablespoon water, for egg wash
- Skip this and brush with milk or oil for a vegan version.
Flaky sea salt, optional, for sprinkling on top

Equipment

Large deep skillet or Dutch oven, oven safe if possible
Medium saucepan for cooking lentils
Cutting board and sharp knife
Wooden spoon or spatula
Rolling pin and pastry brush
9 inch pie dish or 2 quart baking dish if skillet cannot go in the oven
Measuring cups and spoons

Quick Tips & substitutions

Use pre cut fresh or frozen butternut squash to save 10 to 15 minutes of prep.
Swap puff pastry with a refrigerated pie crust if you prefer a more traditional top.
Use canned lentils in a pinch; drain and rinse 2 cans, then simmer in the sauce for a shorter time.
Stir in a splash of balsamic vinegar or apple cider vinegar at the end to brighten the flavors.
Use tamari or coconut aminos instead of soy sauce if you avoid gluten or soy.
Add a spoonful of miso paste to the broth for deeper savory flavor.
Keep the filling slightly thick on the stove since it loosens a bit in the oven.
Cut small slits in the crust so steam escapes and the top stays crisp.

How to Make Lentil Pot Pie with Butternut Squash

Step 1: Cook the lentils

Add the rinsed lentils and vegetable broth to a medium saucepan.
Bring the mixture to a boil over medium high heat, then lower to a gentle simmer.
Cook the lentils for 18 to 22 minutes until they turn tender but still hold shape.
Drain any excess liquid and set the lentils aside.

Step 2: Sauté the vegetables

Heat the olive oil in a large deep skillet over medium heat.
Add onion, carrots, and celery, then cook 5 to 7 minutes until the veggies soften and the onion turns translucent.
Stir in the butternut squash and cook 5 minutes more so the edges start to soften.
Add the garlic and cook 1 minute until it smells fragrant.

Step 3: Build flavor

Stir in the tomato paste, soy sauce or tamari, thyme, rosemary, smoked paprika, salt, and pepper.
Coat the vegetables in the seasonings and cook 2 minutes so the tomato paste darkens slightly.
Sprinkle the flour over the vegetables and stir well to coat everything.
Cook the flour mixture 1 to 2 minutes to remove the raw taste.

Step 4: Make the creamy gravy

Slowly pour in the milk while you stir constantly to avoid lumps.
Bring the mixture to a gentle simmer and stir often as it thickens into a gravy.
Add the cooked lentils and frozen peas, then stir to combine.
Taste and adjust salt, pepper, or soy sauce as needed, then turn off the heat.

Step 5: Assemble the pot pie

If your skillet can go in the oven, keep the filling right in the pan. Otherwise, transfer the mixture to a 9 inch pie dish or 2 quart baking dish.
Roll the puff pastry on a lightly floured surface to fit your dish with a little overhang.
Lay the pastry over the hot filling and tuck the edges down along the sides.
Cut 3 to 4 small slits in the top with a sharp knife so steam can escape.

Step 6: Add shine and bake

Brush the pastry with the egg wash or your milk or oil alternative.
Sprinkle flaky sea salt on top if you like a little crunch.
Bake at 400°F for 25 to 30 minutes until the crust turns deep golden and puffs up.
Remove the pot pie from the oven and let it rest 10 to 15 minutes so the filling sets slightly.

Step 7: Serve

Scoop big spoonfuls of crust and filling into shallow bowls.
Add fresh herbs on top if you have them, like parsley or thyme.
Serve hot and enjoy that cozy lentil and butternut squash goodness.

Recipe Variations

Gluten free: Use gluten free all purpose flour and a gluten free puff pastry or crust.
Vegan: Use non dairy milk, skip the egg wash, and choose a vegan puff pastry brand.
Low carb: Swap half the butternut squash with cauliflower florets and reduce the peas.
Extra protein: Add cooked chickpeas or white beans along with the lentils.
More veggies: Stir in chopped kale or spinach near the end of cooking the filling.
Herby twist: Use fresh thyme and rosemary instead of dried and double the amount.

Ways to Serve

Spoon the pot pie over creamy mashed potatoes for extra comfort.
Serve with a simple green salad with lemony vinaigrette to cut through the richness.
Pair with roasted green beans or broccoli for more veggies on the plate.
Pack leftovers in a thermos style container for a warm work lunch.

Storage Success

Let the Lentil Pot Pie with Butternut Squash cool to room temperature, then cover the dish tightly or transfer portions to airtight containers. Store in the refrigerator for up to 4 days and reheat in the oven at 350°F until hot and bubbly. You can freeze baked portions for up to 2 months; wrap them well and label with the date. Reheat frozen pieces straight from the freezer, covered with foil, until the center heats through and the crust turns crisp again.
