Ingredients You’ll Need
Lentil and vegetable filling
- 2 tablespoons olive oil or avocado oil
- 1 large yellow onion, diced
- 2 medium carrots, diced
- 2 ribs celery, diced
- 3 cloves garlic, minced
- 1 tablespoon fresh thyme leaves, chopped (or 1 teaspoon dried thyme)
- 1 teaspoon dried rosemary, crushed between your fingers
- 1 teaspoon smoked paprika (gives a subtle smoky depth)
- 1 teaspoon ground cumin
- 1 bay leaf
- 1 cup brown or green lentils, rinsed and drained
- Use French green lentils if you like a firmer texture.
- 2 cups peeled and cubed butternut squash (about ½‑inch cubes)
- Frozen butternut squash works well and saves peeling time.
- 1 cup frozen peas
- 3 tablespoons tomato paste
- 3 tablespoons soy sauce or tamari
- 1 tablespoon balsamic vinegar
- 3 cups vegetable broth
- Use low sodium broth so you control the salt level.
- ½ cup full-fat coconut milk or heavy cream
- 2 tablespoons cornstarch or arrowroot powder mixed with 3 tablespoons cold water (slurry)
- ½ teaspoon black pepper, plus more to taste
- 1 to 1½ teaspoons kosher salt, to taste
Crust options
Choose one of these, depending on your mood and pantry.
- 1 sheet store-bought puff pastry, thawed
- I like Pepperidge Farm or Trader Joe’s; keep it cold so it puffs nicely.
- or 1 sheet store-bought pie crust
- or 2 cups prepared biscuit dough (drop biscuits on top for a rustic look)
Egg wash or dairy-free finish
- 1 egg beaten with 1 tablespoon milk, for glossy crust
- or 2 tablespoons plant milk mixed with 1 teaspoon maple syrup, for a vegan-friendly shine
Equipment list
- Large skillet, deep sauté pan, or Dutch oven
- Cutting board and sharp chef’s knife
- Wooden spoon or heat-safe spatula
- 9‑inch pie dish or 2‑quart baking dish
- Rolling pin if you use pie crust instead of puff pastry
- Pastry brush for egg wash or plant milk wash
- Measuring cups and spoons
Tips & Tricks
- Pre-cook the lentils until just tender so they keep a nice bite in the oven.
- Cut the butternut squash into small, even cubes so it cooks through at the same time as the lentils.
- Use frozen chopped onions, carrots, and squash if you want to shorten prep time.
- Keep puff pastry very cold; warm dough turns floppy and loses its puff.
- Taste the filling before you add the crust and adjust salt, pepper, and acidity with extra soy sauce or balsamic.
- Vent the crust with a few slits so steam escapes and the top stays crisp, not soggy.
- Place the pie dish on a sheet pan to catch any bubbling filling and save your oven from drips.
- Let the pot pie rest 10 to 15 minutes after baking so the gravy thickens and slices hold together.
How to Make Lentil Pot Pie with Butternut Squash
Step 1: Sauté veggies and aromatics
Heat oil in a large stock pot or Dutch oven over medium heat. Once hot, add onions, carrots, and celery; cook until soft and lightly golden, about 8 minutes, and stir often. Add garlic, thyme, rosemary, smoked paprika, cumin, and bay leaf; cook 2 minutes until the mixture smells fragrant. Season with a pinch of salt and pepper.
Step 2: Simmer lentils and squash
Add lentils, butternut squash, tomato paste, soy sauce, balsamic vinegar, and vegetable broth to the pot. Stir well so the tomato paste dissolves into the liquid. Bring the mixture to a gentle boil, then lower the heat and simmer until the lentils and squash turn tender, about 20 to 25 minutes, and stir occasionally so nothing sticks.
Step 3: Thicken the gravy
Stir the cornstarch or arrowroot slurry to recombine, then pour it into the simmering pot while you stir. Add coconut milk or cream and let the filling bubble for 3 to 5 minutes until the gravy thickens and looks glossy. Taste and adjust seasoning with more salt, pepper, or a splash of balsamic if you want more brightness.
Step 4: Prepare the crust
Preheat the oven to 400°F. Roll out puff pastry or pie crust on a lightly floured surface until it fits your baking dish with a little overhang. If you use biscuit dough, keep it chilled and ready to scoop on top later.
Step 5: Assemble the pot pie
Remove the bay leaf from the filling. Spoon the hot lentil and butternut squash mixture into your pie dish or baking dish and spread it in an even layer. Lay the puff pastry or pie crust over the top, tuck in the edges, and crimp them against the rim of the dish, or drop biscuit dough in small mounds over the surface.
Step 6: Add vents and wash
Cut 3 to 4 small slits in the top crust with a sharp knife so steam can escape. Brush the surface with egg wash or plant milk mixture for a golden finish. Sprinkle a pinch of flaky salt or dried thyme on top if you like a little extra flair.
Step 7: Bake
Place the dish on a sheet pan and slide it into the oven. Bake 25 to 30 minutes, until the crust turns deep golden and the filling bubbles around the edges. If the edges brown too quickly, tent them loosely with foil and keep baking until the center looks puffed and cooked through.
Step 8: Rest and serve
Remove the Lentil Pot Pie with Butternut Squash from the oven and set it on a cooling rack. Let it rest 10 to 15 minutes so the gravy thickens and slices stay neat. Ladle generous scoops into bowls and enjoy that cozy, savory aroma that fills the kitchen.
What to Serve with Lentil Pot Pie with Butternut Squash
Serve Lentil Pot Pie with Butternut Squash with a bright green salad, such as mixed greens with lemony vinaigrette, to cut through the richness. Steamed green beans, roasted Brussels sprouts, or simple sautéed spinach pair nicely with the hearty filling. Offer a side of applesauce or sliced fresh fruit if you cook for kids or want a lighter contrast. Pour sparkling water with citrus slices or a warm mug of herbal tea to round out the meal.
