Vegetarian Mince & Onion Pie Recipe for Comforting Weeknight Meals

The British classic mince and onion pie gets a vegetarian makeover here — lighter yet incredibly comforting. This easy-to-follow recipe is packed with flavour and pairs beautifully with traditional Sunday sides like Yorkshire puddings and crispy roast potatoes. It’s also simple to adapt to a vegan version.

Savoury pies are a firm favourite in the UK — whether they headline a Sunday roast or come with chips and gravy from the local chippy. This vegetarian take keeps everything familiar: hearty, filling and deeply satisfying, like a traditional British pie made without meat.

I gave up eating meat over two years ago and haven’t missed it. Removing meat from my diet opened up new flavours and techniques, and this recipe was born from a craving for a straightforward, comforting homemade pie — not an overcomplicated vegetarian novelty, just a proper British pie made meat-free.

My vegetarian mince and onion pie is simple to prepare with easy-to-find ingredients. It’s reliable, tasty and perfect for family dinners — I hope you enjoy it as much as I do.

Can you make this mince and onion pie vegan?

Yes. The filling itself is naturally vegan, but always check labels. To make the recipe fully vegan, use shop-bought shortcrust pastry labelled vegan (many are accidentally vegan) and skip the egg wash or use a plant-based brush for a golden finish.

Recipe summary

Here’s a quick overview of the method:

1. Make the shortcrust pastry by rubbing cold cubed butter into flour and seasoning, then add cold water, form a dough, wrap and chill for 1 hour.
2. Sauté onion and garlic, then add frozen soya mince and cook until warmed through.
3. Stir in prepared onion gravy, a vegetable stock pot, balsamic vinegar, and seasoning; cook briefly and allow to cool.
4. Roll out pastry and line a pie dish, add cooled filling, top with pastry lid, trim and crimp the edges, then brush with beaten egg (or alternative).
5. Bake for 45 minutes until golden.

Ingredients

Everything you need for a 4-person pie.

• Flour: Plain/all-purpose flour for shortcrust pastry.
• Salt: Regular table salt.
• Butter: Unsalted, cold and cubed (for better control of seasoning).
• Oil: Olive oil preferred for flavour; vegetable or sunflower works too.
• Garlic: Use large cloves or increase quantity to taste.
• Onion: One yellow onion, diced.
• Meat-free mince: Frozen varieties work well and are economical.
• Gravy: Onion gravy (prepared from granules or fresh).
• Vegetable stock pot: Or stock cube, whichever you prefer.
• Balsamic vinegar: A tablespoon to deepen the filling’s flavour.

Recipe tips

Small details make a difference:

• Cube butter small for faster rubbing into the flour.
• Keep butter cold to avoid greasy pastry.
• Season the filling while it cooks rather than at the end to build balanced flavour.
• Let the filling cool before filling the pastry to prevent a soggy base.
• Brush with beaten egg (or plant alternative) for a glossy golden finish.
• Bake the pie on a tray to catch any spillover.

This recipe includes UK metric and US cup measurements.

Ingredients (serves 4)

Pastry

• 210g (1 + 2/3 cup) plain flour (plus extra for dusting)
• 1/2 tsp salt
• 115g (1/2 cup) unsalted butter, cold & cubed
• 5–6 tbsp cold water
• 1 egg, beaten (for brushing) or vegan alternative

Filling

• 2–3 tbsp olive oil
• 1 onion, diced
• 2 large garlic cloves, minced
• Salt & pepper
• 250g (8.8 oz) frozen soya/meat-free mince
• 400ml onion gravy
• 1 vegetable stock pot
• 1 tbsp balsamic vinegar

Essential equipment

• Large mixing bowl
• Pastry blender (optional)
• Large frying pan
• Wooden spatula
• Measuring jug
• Rolling pin
• 18cm (7″) baking dish
• Sharp knife
• Baking tray

Pastry method

Mix flour and salt in a large bowl, add cold cubed butter and rub with your fingertips until it resembles fine crumbs. Gradually add cold water until a scrappy dough forms. Flatten into a disc, wrap and chill for 1 hour.

Filling method

While the pastry chills, heat oil in a frying pan over medium-low heat. Cook the diced onion for 4–5 minutes until translucent. Add minced garlic and cook for 1 minute. Add frozen mince and cook until defrosted and warmed through.

Prepare the gravy if using granules, then add gravy, vegetable stock pot, balsamic vinegar and seasoning to the pan. Stir and simmer for about 5 minutes until the mixture is moist but starts to thicken. Remove from heat and allow to cool; it will firm up slightly as it stands.

Assembly and baking

Preheat the oven to 210ºC / 200ºC fan / 410ºF. Roll chilled pastry to about 2mm thickness and line an 18cm (7″) baking dish. Trim excess and re-roll scraps for the lid and decorations. Fill with cooled mince mixture, place the lid on top, trim and crimp edges to seal. Brush with beaten egg or alternative, cut a small vent in the centre and bake on a tray for 45 minutes until deep golden. Allow to rest for 10–15 minutes before slicing for cleaner portions.

Serve the pie hot with your preferred sides — roast potatoes, vegetables or Yorkshire puddings all work wonderfully. Enjoy!
