The Complete Cooking Journey

Making this cheese and onion pie is a rewarding experience from start to finish. The aroma of onions slowly cooking in butter fills the kitchen, building anticipation for the delicious meal ahead. Once combined with cheese and tucked into a crisp pastry shell, the filling transforms into a comforting dish that’s both simple and satisfying.

Ingredients:

For the Pie

• 1 sheet shortcrust pastry
• 2 tbsp butter
• 3 large onions, thinly sliced
• 2 cups mature cheddar cheese, grated
• 2 tbsp plain flour
• 2 tbsp milk
• 1 tsp Dijon mustard
• Salt, to taste
• Black pepper, to taste

For the Egg Wash

• 1 egg, beaten

Method:

Step 1: Prepare the Onions

Melt the butter in a large frying pan over medium heat. Add the sliced onions and cook slowly for 15 to 20 minutes until soft and lightly golden.

Step 2: Make the Filling

Remove the onions from the heat and allow them to cool slightly. Stir in the grated cheddar cheese, flour, milk, mustard, salt, and pepper until fully combined.

Step 3: Prepare the Pastry

Preheat the oven to 400°F (200°C). Roll out the pastry and line a pie dish, leaving enough pastry for the top if desired.

Step 4: Fill the Pie

Spoon the cheese and onion mixture evenly into the pastry-lined dish.

Step 5: Add the Top Crust

Cover with the remaining pastry or create a lattice top. Seal the edges and trim any excess pastry.

Step 6: Apply Egg Wash

Brush the top with beaten egg to help achieve a beautiful golden finish.

Step 7: Bake

Bake for 30 to 35 minutes, or until the pastry is crisp and golden brown.

Step 8: Rest and Serve

Allow the pie to rest for 10 minutes before slicing and serving.

Serving Suggestions & Pairings

Serve the pie with mashed potatoes, steamed vegetables, roasted carrots, or a fresh green salad. It also pairs wonderfully with baked beans or a bowl of warm soup.

Storage & Leftovers Guide

Store leftover pie in an airtight container in the refrigerator for up to 3 days. Reheat in the oven to maintain the pastry’s crisp texture. The pie can also be frozen for up to 2 months.
