• 1 carrot, diced

• 1 celery stalk, diced

• 1 teaspoon dried thyme (or 1 tablespoon fresh)

• 1 teaspoon dried rosemary (or 1 tablespoon fresh)

• ½ teaspoon smoked paprika (optional)

• 1½ cups cooked lentils (or 1 can, drained & rinsed)

• 1 tablespoon tomato paste

• 1 teaspoon balsamic vinegar

For the Pastry:

Step-by-Step Instructions

1. Prepare the Filling

1. In a large skillet, heat olive oil over medium heat.

2. Add chopped onion and sauté for 3–4 minutes until softened.

3. Stir in garlic, mushrooms, carrot, and celery. Cook for 8–10 minutes until veggies are tender and most liquid has evaporated.

4. Add thyme, rosemary, and smoked paprika. Stir and cook for another minute.

5. Mix in lentils, tomato paste, vegetable broth, soy sauce, and balsamic vinegar. Simmer for 5 minutes.

6. Sprinkle flour or cornstarch and stir to thicken. Let the filling cool slightly before assembling.

2. Assemble the Pie

1. Preheat oven to 375°F (190°C).

2. Roll out the puff pastry and gently press into a pie dish. Trim any overhanging edges.

3. Spoon the filling into the pastry-lined dish.

4. Lay another puff pastry sheet over the top. Crimp the edges to seal.

5. Cut a few slits in the top for steam to escape.

6. Brush with egg wash or plant-based milk.

3. Bake

1. Bake for 30–35 minutes until golden and crisp.

2. Cool for 5 minutes before slicing and serving.

Equipment You’ll Need

• Large skillet

• Wooden spoon or spatula

• Chopping board and knife

• Measuring cups and spoons

• Pie dish or oven-safe baking dish

• Pastry brush (for egg wash)

• Rolling pin (optional, if adjusting pastry size)

• Oven

Recipe Tips and Variations

1. Vegan Version:
Skip the egg wash and use plant-based milk (like almond or soy) for a golden finish. Ensure the puff pastry you’re using is dairy-free.

2. Gluten-Free Adaptation:
Use gluten-free puff pastry and swap soy sauce for tamari. Cornstarch is naturally gluten-free and works beautifully as a thickener.

3. Add More Veggies:
Chopped kale, spinach, or even sweet potato can be added to the mix for a veggie-loaded pie.

4. Spice it Up:
If you like a bit of heat, try adding crushed red pepper flakes or a dash of cayenne.

5. Make it Cheesy:
Sprinkle some shredded cheese (like gruyère or vegan mozzarella) into the filling before sealing it up.

How to Store and Reheat

Storage:
Allow the pie to cool completely before covering with foil or transferring to an airtight container. Store in the refrigerator for up to 4 days.

Freezing:
Wrap individual slices or the whole pie tightly in plastic wrap and foil. Freeze for up to 3 months.

Reheating:
From fridge: Bake at 350°F (175°C) for 10–15 minutes until warmed through.
From frozen: Let thaw overnight in the fridge, then reheat as above.

What to Serve with Lentil Mushroom Pie

This pie is hearty enough to stand on its own, but here are a few tasty pairings to round out your meal:

• Side Salad: A fresh green salad with lemon vinaigrette adds brightness.

• Roasted Veggies: Think Brussels sprouts, carrots, or parsnips.

• Red Wine: A medium-bodied red like Pinot Noir or Merlot complements the earthy filling.

• Gravy: A rich vegetarian or mushroom gravy takes it to the next level.

Frequently Asked Questions (FAQ)

Can I use canned lentils?
Yes! One 15-oz can of lentils (drained and rinsed) equals about 1½ cups cooked lentils.

What kind of mushrooms are best?
Cremini mushrooms offer a meaty texture and robust flavor, but any kind will work—including a mix for depth.

Can I make this ahead of time?
Absolutely. Prepare the filling and store it in the fridge for up to 2 days. Assemble and bake when ready.

What if I don’t have a pie dish?
No problem. A rectangular baking dish or even a cast-iron skillet can work in a pinch.

Is puff pastry the only option?
While puff pastry gives a buttery, flaky result, you can also use a shortcrust pastry for a sturdier, more traditional base.
