How we came up with this recipe

We’re using ready-made pastry here because life is short and the addition of cheese sauce puts this veggie pie on a whole other level. 

Tinned lentils add protein (you could use a different type of cooked, canned beans if you prefer).

Homity Pie’, a traditional British vegetarian pie (with a pastry base, not a lid), is said to have been created by the Land Girls out of rations during WWII.

At the time, a vegetarian pie was considered a lowly cousin to the meat pie. I hope this one changes your mind!


Notes on Vegetarian Pie ingredients

The ingredients for a cheesy vegetarian pie laid out on a counter.
  • Olive oil – Not extra virgin
  • Leeks – Fresh or frozen is fine
  • Mushrooms – I used chestnut but for extra flavour you could use a pack of wild mushrooms or use a mix of different varieties
  • Sweetcorn – Tinned kind, drained (or you could use frozen, defrosted)
  • Brown or green lentils – Tinned kind
  • Milk – Any kind. Choose plant-based if you prefer
  • Plain flour – You can use gluten-free flour instead 
  • Grated cheddar cheese – This needs to be mature for flavour. Alternatively use vegan cheese
  • Ready-rolled puff pastry – Use a gluten-free pastry if preferred
  • Egg – Use milk if you prefer

Step 3 in the recipe for Vegetarian Pie.

Substitutions

  • Vegetables – For extra flavour you could use a pack of wild mushrooms or use a mix of different varieties.
  • Vegan alternatives – This pie can be made into a vegan dish by replacing the cheese with a vegan variety, use a plant-based cream, nut milk and olive oil spread, and make sure the puff pastry you buy has been made with olive oil, using the nut milk as an egg wash.

Leftovers

In the fridge You can keep this recipe in the fridge for 3 days. Reheat fully in the microwave or covered in the oven before serving. (Reheating in the microwave will make the pastry a little soggy, beware.)

In the freezer This is OK to freeze UNBAKED. Then defrost and bake it when you’re ready to eat it. You can freeze the already cooked leftovers at a push, but once the pastry is baked and defrosted it can be a bit soggy.

Top tips

Using ready rolled pastry

Bring the pastry from the fridge about 10 minutes before using it. If you take it out too soon it will be very sticky and difficult to handle. Equally, if you use it straight from the fridge it can crack! 

Mushroom cooking time

Your cooking time here will depend on the type of mushrooms you use, and how much liquid they give out. I used chestnut mushrooms, which don’t give off a lot of liquid so the 5 minutes is sufficient. If there’s a lot of water as you cook your mushrooms and leeks, you may need to cook for an extra 5-10 minutes until it evaporates.

Serving suggestion

You could serve slices of this pie with some steamed greens and new potatoes. Or how about Oven Chips or Parmentier Potatoes?

Topping decoration

I cut pastry stars out for the topping from my cutter set (here are the cutters I use). I then used the beaten egg to stick them back on. I like to cut one out of the middle too so you can see the filling peeking through!

Cheesiness

A vegetable pie is a great way to use up any cheese you have leftover that’s not getting eaten. You can use something with strong flavours like blue cheese too. Just substitute the cheese in the recipe for the same weight.

FAQs

Can I add meat to the pie?

I think this works best as it is, but if you do want a few meat pie recipes, try my easy Steak Pie or my Chicken Pie instead.

Can I make this pie gluten free?

Yes, substitute the flour and pastry for gluten free versions.
