Ingredients

• 2 cups Leftover beef roast
• 3 cups Leftover mashed potatoes
• 1 cup Carrots
• 1 cup Peas
• 1 large Onion
• 2 cloves Garlic cloves
• 1 cup Beef broth
• 2 tablespoons Flour
• 2 tablespoons Butter
• 1 tablespoon Olive oil
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Dried thyme
• 0.5 cup Shredded cheese (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Dice the leftover beef roast into small, bite-sized pieces and set aside.

Step 3

Finely chop the onion and mince the garlic. Peel and dice the carrots into small pieces.

Step 4

Heat the olive oil in a large skillet over medium heat. Add the chopped onion and garlic, and sauté for 2-3 minutes until fragrant and softened.

Step 5

Add the diced carrots to the skillet and cook for an additional 5 minutes until they begin to soften.

Step 6

Stir in the butter until melted, then sprinkle the flour over the vegetables. Cook for 1-2 minutes to form a roux.

Step 7

Slowly pour the beef broth into the skillet, stirring constantly to create a smooth sauce.

Step 8

Add the peas, diced beef, salt, pepper, and thyme to the mixture. Stir well and let the filling simmer for 5 minutes, allowing it to thicken. Remove from heat.

Step 9

Transfer the beef and vegetable mixture into a 9-inch square or round baking dish, spreading it out evenly.

Step 10

Spoon the leftover mashed potatoes over the filling, smoothing it out to cover the entire surface. Use a fork to create texture on top for added crispiness.

Step 11

If desired, sprinkle shredded cheese over the mashed potatoes for an extra layer of flavor.

Step 12

Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the filling is bubbling.

Step 13

Remove from the oven and let cool for 5 minutes before serving. Enjoy your hearty shepherd's pie!
