Ingredients

• 500 grams Leftover roast beef
• 1 large Yellow onion
• 2 medium Carrot
• 2 medium Celery stalk
• 150 grams Frozen peas
• 50 grams Butter
• 2 tablespoons All-purpose flour
• 500 milliliters Beef stock
• 1 tablespoon Worcestershire sauce
• 1 teaspoon Fresh thyme
• 800 grams Mashed potatoes
• 50 milliliters Milk
• 100 grams Cheddar cheese, grated
• 0 to taste Salt
• 0 to taste Black pepper

Directions

Step 1

Preheat the oven to 200°C (400°F).

Step 2

Finely dice the onion, carrots, and celery stalks.

Step 3

In a large skillet, melt 25 grams of butter over medium heat and sauté the onions, carrots, and celery for 5-7 minutes until softened.

Step 4

Shred the roast beef into small pieces and add it to the skillet along with the peas. Stir well to combine.

Step 5

Sprinkle the flour over the mixture and stir to coat. Cook for 1-2 minutes to remove the raw flour taste.

Step 6

Gradually add the beef stock while stirring, ensuring there are no lumps. Bring the mixture to a simmer and let it thicken for 3-5 minutes.

Step 7

Stir in the Worcestershire sauce, thyme, and season with salt and pepper to taste. Remove from heat and transfer the beef mixture to a baking dish, spreading it out evenly.

Step 8

Prepare the mashed potato topping by combining the mashed potatoes, remaining 25 grams of butter, and milk in a bowl. Mix until creamy and smooth.

Step 9

Spread the mashed potatoes over the beef mixture in the baking dish, ensuring it completely covers the filling.

Step 10

Sprinkle the grated cheddar cheese over the mashed potatoes for a golden, cheesy crust.

Step 11

Place the baking dish in the preheated oven and bake for 25-30 minutes or until the top is golden brown and bubbling.

Step 12

Remove from the oven and let rest for 5 minutes before serving.
