Instructions

1. 1

   Prepare vegetables

   Dice the onion, carrot, potato and celery into small, similarly sized cubes. Finely dice the garlic and slice the mushrooms.

2. 2

   Cook the vegetables

   Heat 1 tablespoon of olive oil in a large frying pan over medium heat. Add the onion, carrot and celery with a good pinch of salt and sauté for a few minutes.

3. 3

   Brown the mushrooms

   Add the garlic and mushrooms to the pan and sauté until the mushrooms have browned.

4. 4

   Thicken the filling

   Add the second tablespoon of olive oil, flour and chopped rosemary, then season with salt and pepper. Cook together for a few minutes, until most of the flour has dissolved.

5. 5

   Simmer the filling

   Pour in the vegetable broth, then add the potato, soy sauce and milk. Stir and simmer with the lid on over low heat for 5 minutes.

6. 6

   Cool the filling

   Take the pan off the heat and remove the lid. Stir in the frozen peas and leave the mixture to cool; transfer it to a large bowl or plate if you want it to cool more quickly.

7. 7

   Prepare the pastry

   Meanwhile, preheat the oven to 180°C (350°F). Fit the pie crust into a round 26 cm (10-inch) oven dish, shaping it gently to the dish. Trim away any excess pastry hanging over the edge.

8. 8

   Fill the dish

   Once the filling has cooled and thickened, spoon it into the pastry-lined dish. Level the surface with a spatula or the back of a spoon.

9. 9

   Seal the pie

   Lay the puff pastry over the filling. Tuck its edges behind the pie crust all the way around and press lightly with your fingers. Make gentle fork marks around the edge to help seal it.

10. 10

    Finish the top

    Cut 5–6 slits in the pastry to let steam escape. Brush the top with whisked egg or olive oil, then sprinkle over sesame seeds.

11. 11

    Bake and rest

    Place the dish on the oven’s bottom shelf and bake for 40 minutes, until the top is golden brown. If the edges brown too quickly, cover them with foil. Remove the pie carefully and leave it to cool for 10 minutes before serving.

What is vegetable pot pie?

Pot pie is a savoury pie associated with American home cooking, typically made with a hearty filling enclosed or topped with pastry. This version uses a pastry base and a separate puff pastry lid, giving it a tender bottom and a crisp top.

Mushrooms, potatoes and mixed vegetables make the filling substantial, while a flour-thickened broth and milk bring the ingredients together into a creamy sauce.

Nutrition and macros by portion

The nutrition label shows one serving as written: 391 calories, 8g protein, 43g carbs, 21g fat.

The potatoes, flour and pastry provide most of the carbohydrates, while the pastry and olive oil account for much of the fat. Mushrooms, peas, milk and the other vegetables contribute some protein, though this is a vegetable-led dish. Serve a slice with a generous portion of green vegetables or salad to round out the plate.

Build the vegetable base

Even dice: Cutting the onion, carrot, potato and celery into similar small pieces helps them cook at a more even pace.

Brown the mushrooms: Add them after the first vegetables have had a few minutes in the pan. Let them colour before adding the flour so their flavour develops rather than leaving them pale and watery.

Make a smooth filling

Flour first: Stir the flour into the vegetables and oil before adding the liquid. A few minutes of cooking helps distribute it through the mixture.

Add the liquid: Stir in the broth and milk, then simmer with the lid on for 5 minutes. The filling thickens further as it cools, so let it settle before putting it into the pastry.

Give the pastry a good seal

Tucked edges: Fold the puff pastry edge behind the pie crust around the dish, then use a fork to press a light pattern into the join. This helps keep the lid in place as the filling heats.

Steam slits: Cut 5–6 openings in the top before baking. They allow steam to escape, while the egg or oil brushing encourages browning.

Watch the bake

Golden top: Bake on the bottom shelf at 180°C for 40 minutes, until the pastry is golden brown. Keep an eye on the edges as they may colour faster than the middle.

Foil cover: If the edges darken too quickly, shield them with foil for the remainder of the bake. Rest the pie for 10 minutes after taking it out so the filling is easier to portion.

What to serve alongside

Fresh sides: A crisp green salad or simply dressed greens add a fresh contrast to the creamy filling and buttery pastry.

For a fuller spread, serve with extra cooked vegetables. Keep the side seasoning simple so the rosemary and mushrooms remain prominent.

Recipe notes & tips

• Dice the vegetables to a similar size so they cook evenly.
• Let the mushrooms brown before stirring in the flour.
• Cool the filling before assembling so it has time to thicken.
• Cut 5–6 slits in the pastry lid to release steam.
• Cover the pastry edges with foil if they brown faster than the centre.
• Rest the baked pie for 10 minutes before slicing.

Variations

• Use a pie-crust lid: Swap the puff pastry sheet for a second pie crust, as suggested in the ingredient list.
• Choose soy milk: Use soy milk in place of dairy milk for the filling.
• Change the herbs: Replace the rosemary with chopped thyme for a different herbal note.
• Add extra peas: Stir more peas into the filling if you want a sweeter, more vegetable-packed pie.
• Adjust the seasoning: Use low-sodium broth and soy sauce, then season the filling to taste.

Common mistakes to avoid

• Uneven vegetable pieces: Keep the onion, carrot, potato and celery in similarly sized small cubes so they cook at a similar rate.
• Pale mushrooms: Give the mushrooms time to brown before moving on to the flour.
• Runny filling: Cool the mixture before assembly; it thickens as it stands.
• Loose pastry join: Tuck the lid behind the base and press around the edge with a fork.
• No steam vents: Cut 5–6 slits in the pastry before it goes into the oven.
• Over-browned edges: Cover the edges with foil if they colour too quickly.

How to store

Refrigerate leftover pie in a covered container for up to 3 days. Reheat portions in an oven until hot throughout; this helps the pastry crisp up again. The pastry may soften somewhat after storage.
