There’s nothing better than a comforting pot pie on a cool night, and this Vegan Dump & Bake Seitan Veggie Pot Pie has become a household favourite. It’s completely dairy-free yet so creamy, thanks to the lentil cream and soy milk base. I love how it’s genuinely simple – no stove-top cooking, just whisk, dump, and bake. Seitan gives this dish a hearty texture and a big boost of plant protein, making it super satisfying and nourishing. I made my own, but you can always buy it online if you don’t want the extra hassle. The filo pastry topping bakes up crisp and flaky without the fuss of rolling dough. I also love that you can use whatever veggies you have on hand, which makes it practical and budget-friendly. The veggie stock and thyme give it a gourmet feel, while still being easy enough for a weeknight. It’s a dish that feels indulgent but is actually full of fibre, protein, and essential nutrients. Plus, it’s freezer-friendly and perfect for meal prep.
Main Ingredients & Why We Use Them
- Vegan Butter – Provides richness and helps the sauce emulsify.
- Unsweetened Soy Milk – A creamy base with extra protein; oat milk also works.
- Dijon Mustard – Adds tang and depth of flavour.
- Lentil Cream – A wholesome alternative to dairy cream that thickens and adds protein.
- Vegetable Stock – Brings umami and helps thin the sauce.
- Garlic – A savoury essential that builds flavour.
- Dried Thyme – Adds herby depth; fresh thyme sprigs are even better.
- Dry White Wine – Adds acidity and complexity; stock works if you prefer alcohol-free.
- Plain Flour – Thickens the sauce to a silky consistency.
- Black Pepper & Salt – Balance and enhance all the flavours.
- Vegan Parmesan or Nutritional Yeast – Adds a cheesy savouriness without dairy.
- Brown Onion, Carrots & Celery – Classic aromatic base for soups and pies.
- Frozen Peas – Quick, easy, and naturally sweet.
- Steamed Seitan – The protein hero, with a meaty texture that makes this pie hearty.
- Filo Pastry – Creates that signature crisp, golden top with less effort than puff pastry.
- Olive Oil or Soy Milk – Brushed on filo sheets for a glossy, golden finish.
Veggie Pot Pie Sauce Ingredients
Veggie Pot Pie Filling + Topping Ingredients
How to Make It
Making this vegan seitan pot pie is as easy as whisk, dump, and bake. Simply whisk together the creamy sauce ingredients in a deep baking dish, stir in the veggies and seitan, then cover with scrunched layers of filo pastry. Brush with olive oil or soy milk for crispness, bake until golden, and you’ve got a hearty, bubbling pot pie ready to serve.
Variations and Substitutes
You can swap seitan for cooked chickpeas or shredded jackfruit for a gluten-free option. Lentil cream can be replaced with cashew cream or coconut cream, depending on your dietary needs. If you don’t have filo pastry, puff pastry makes a rich alternative. For extra greens, stir in spinach or kale before baking.
Equipment
You’ll need a large, deep ovenproof baking dish that can hold the sauce, veggies, and seitan comfortably. A whisk is useful for blending the sauce, and a pastry brush makes it easy to coat filo sheets with oil. Other than that, you only need a sharp knife and chopping board for prepping your vegetables.
How to Serve It
This pot pie is a complete meal on its own, but it pairs beautifully with a simple side salad for freshness. For something extra cosy, serve with mashed potatoes or steamed greens.
How to Store It
Leftovers keep well in an airtight container in the fridge for up to 3 days. Reheat in the oven to keep the pastry crisp. You can also freeze individual portions for up to 2 months – just thaw overnight in the fridge and reheat until piping hot.
Can I Make It Ahead of Time?
Yes, you can definitely make this ahead of time, and you’ve got two good options depending on what works best for you:
Bake ahead and reheat later
- This is the easiest option if you want everything ready to go.
- Bake the pot pie completely, let it cool, then cover tightly and refrigerate for up to 3 days.
- When reheating, pop it back in the oven at 180 °C (fan 160 °C) until warmed through (about 20–25 minutes). The filo will crisp up again nicely.
Assemble ahead, bake fresh
- If you want the crispiest filo topping, assemble the filling and sauce in your baking dish and store covered in the fridge for up to 24 hours.
- Just before serving, add the filo pastry layers and bake as per the recipe.

Topping
- 12 sheets filo pastry thawed slightly

Instructions
Whisk the sauce

Add the filling

Layer pastry

Bake
- Place into a preheated oven at 190°C (375°F) for 30–35 minutes, until the pastry is golden and crisp and the filling is bubbling underneath.
