Cheese and Onion Pie is one of those old-fashioned British bakes that never really goes out of style.

Kitchen Equipment Needed

You don’t need anything fancy to pull this pie together, just a few basics you likely already own.

This same shortcrust technique works beautifully in my Air Fryer Quiche Recipe too, if you’re looking for a smaller, quicker version of a savory pastry bake.

Recommended Products for This Recipe

These are a few products I personally rely on when I make this pie, based on years of trial and error in my own kitchen.

1. Colman’s English Mustard Powder

A small pinch of this mustard powder gives the filling that classic British pub-pie tang without making the pie taste like mustard at all.

It’s the ingredient that separates a good cheese and onion pie from a great one.

A little tin lasts a long time, so it’s a worthwhile pantry addition.

2. Extra Sharp Vermont Cheddar Cheese

The sharper the cheddar, the more flavor comes through once the onions mellow out during baking.

I’ve tried mild cheddar in this recipe before, and it just doesn’t compare to using an aged, extra sharp block.

Grating your own block also melts smoother than pre-shredded bags.

Get it on Amazon

3. Emile Henry Ceramic Pie Dish

A heavy ceramic dish holds heat evenly, which helps the bottom crust cook through instead of turning soggy under the cheesy filling.

I’ve had mine for years and it still browns pastry beautifully every single time.

It also looks great going straight from the oven to the table.

Get it on Amazon

4. Microplane Professional Box Grater

A sharp box grater makes shredding a full block of cheddar quick and painless, and it grates onions finely too if you prefer a smoother filling.

The finer shreds also melt more evenly into the egg mixture.

Cleanup is easy since the blades are designed to release cheese without clogging.

5. OXO Good Grips Rolling Pin

A well-balanced rolling pin makes rolling out cold pastry so much easier, especially if you’re working with a homemade dough rather than store-bought sheets.

The non-stick surface means less flour needed on your counter.

It’s a small upgrade that makes pastry work far less frustrating.

Step-by-Step Instructions: How to Make Cheese and Onion Pie

1. Preheat the Oven and Prepare the Pie Dish

  • Preheat your oven to 400°F (200°C) so it’s fully hot by the time your pie is assembled.
  • Lightly grease your 9 inch pie dish with a thin layer of butter to help prevent sticking.
  • Set the dish aside on your counter while you prepare the pastry and filling.

2. Line the Pie Dish with Pastry

  • Unroll one sheet of shortcrust pastry on a lightly floured surface.
  • Gently lift the pastry and press it into the bottom and up the sides of the prepared pie dish.
  • Trim any excess pastry hanging over the edge with a sharp knife, leaving about half an inch of overhang.
  • Prick the base a few times with a fork to prevent it from puffing up while baking.
  • Place the lined dish in the refrigerator while you make the filling, this helps the pastry hold its shape.

3. Cook the Onions

  • Melt the butter in a large skillet over medium heat.
  • Add the diced onions and a small pinch of salt, stirring to coat them evenly in the butter.
  • Cook the onions for 12 to 15 minutes, stirring occasionally, until they turn soft, translucent, and lightly golden.
  • Remove the skillet from the heat and let the onions cool for about 10 minutes before mixing them into the filling.

4. Make the Cheese Filling

  • In a large mixing bowl, whisk together the 2 eggs, milk, mustard powder, salt, and black pepper until well combined.
  • Add the shredded extra sharp cheddar cheese to the bowl and stir to coat it in the egg mixture.
  • Fold in the cooled cooked onions until everything is evenly distributed.
  • Stir in the chopped chives at this point if you’re using them.

5. Fill the Pie

  • Remove the chilled pie dish from the refrigerator.
  • Pour the cheese and onion filling into the pastry-lined dish, spreading it out evenly with a spatula.
  • Smooth the top of the filling so it sits level from edge to edge.

6. Add the Top Crust and Seal the Pie

  • Unroll the second sheet of pastry and lay it over the top of the filled pie.
  • Trim off any excess pastry, then press the top and bottom edges together firmly with your fingers or a fork to seal.
  • Cut two or three small slits in the center of the top crust to let steam escape while baking.

7. Add the Egg Wash and Bake

  • Whisk the remaining egg with a splash of water or milk to make an egg wash.
  • Brush the egg wash evenly over the top crust using a pastry brush.
  • Place the pie on the middle rack of the preheated oven and bake for 40 to 45 minutes, until the crust is deeply golden brown.
  • If the edges start browning too quickly, loosely cover them with a strip of foil for the remaining bake time.

8. Cool and Slice

  • Remove the pie from the oven and set it on a wire cooling rack.
  • Let the pie rest for at least 15 minutes before slicing, this allows the filling to set properly.
  • Slice into 8 wedges and serve warm.

Tips for The Best Cheese and Onion Pie

A few small details make a big difference between an average pie and a truly great one.

  • Cook the onions low and slow so they turn sweet instead of sharp and raw tasting.
  • Always let the onions cool before mixing them with the eggs, or the eggs will start to scramble.
  • Grate your own cheddar block rather than using pre-shredded bags for a smoother, creamier melt.
  • Chill the pastry-lined dish before filling to help the crust keep its shape in the oven.
  • Let the pie rest fully before slicing so the filling doesn’t spill out.

Serving Suggestions

Cheese and Onion Pie Recipe

This pie is filling enough to serve as a main course, but it also pairs well with lighter sides that balance out its richness.

A simple green salad with a sharp vinaigrette cuts through the creamy filling nicely.

Mashed potatoes, peas, and a splash of gravy turn it into a full traditional British dinner.

  • Steamed green peas with a knob of butter
  • Creamy mashed potatoes and onion gravy
  • A crisp side salad with mustard vinaigrette
  • Pickled onions or piccalilli on the side
  • A warm bowl of tomato soup for dipping

Serve slices alongside a bowl of Potato Leek Soup for a proper cold-weather supper.

Variations of Cheese and Onion Pie

Once you’ve made the classic version, it’s easy to riff on this recipe based on what you have on hand.

  • Swap in Lancashire or red Leicester cheese for a different flavor profile
  • Add cooked, diced potato to the filling for a heartier, stew-like texture
  • Stir in crumbled cooked bacon for a smoky twist
  • Use puff pastry instead of shortcrust for a flakier, lighter crust
  • Make individual hand pies instead of one large pie for easy portioning

Storage and Reheating

This pie holds up really well in the fridge, which makes it a great option for meal prepping ahead of a busy week.

  • Store leftover pie covered in the refrigerator for up to 3 days.
  • Wrap individual slices tightly and freeze for up to 1 month.
  • Reheat in a 350°F oven for about 15 minutes, or until warmed through.
  • Thaw frozen slices in the fridge overnight before reheating for the best texture.
  • Avoid microwaving if possible, since it can make the pastry soggy.

The same reheating trick works well for my Corned Beef and Potato Pie Recipe, another pastry-wrapped dinner that stores beautifully.

Health Benefits of Key Ingredients

While this pie is definitely a comfort food, a few of its core ingredients bring some nutritional upside along with all that flavor.

Onions are rich in antioxidants and contain compounds that may support heart health.

Cheddar cheese provides calcium and protein, both important for strong bones and muscle repair.

Eggs add high-quality protein along with vitamins like B12 and choline.

  • Onions: antioxidants, fiber, and immune-supporting compounds
  • Cheddar cheese: calcium, protein, and vitamin B12
  • Eggs: complete protein, choline, and healthy fats
  • Butter: fat-soluble vitamins A, D, E, and K

FAQs About Cheese and Onion Pie

1. Can I use puff pastry instead of shortcrust pastry?

Yes, puff pastry works well for a lighter, flakier crust.

Just keep in mind that puff pastry rises more, so your baking time may need slight adjusting.

2. Why did my filling turn watery?

This usually happens when the onions aren’t cooked long enough before mixing them in.

Make sure the onions are fully softened and any excess liquid has evaporated in the skillet before combining them with the eggs and cheese.

3. Can I make this pie ahead of time?

Absolutely, this pie is a great make-ahead option for busy days.

Bake it fully, let it cool, then refrigerate it and reheat individual slices whenever you’re ready to eat.

4. What’s the best cheese to use if I can’t find Lancashire cheese?

Extra sharp cheddar is the easiest substitute and gives a similarly bold, tangy flavor.

Red Leicester is another good option if you want a slightly milder, creamier bite.

5. Can I freeze this pie unbaked?

Yes, you can assemble the pie completely, wrap it tightly, and freeze it unbaked for up to a month.

Bake it straight from frozen at 400°F, adding an extra 15 to 20 minutes to the cook time until the center is fully set.
