Ingredients
- 1 lb ground beef
- 1 medium, diced onion
- 1 large, diced carrot
- 1 cup frozen peas
- 2, minced garlic cloves
- 2 tbsp tomato paste
- 1 cup beef broth
- 1 tbsp Worcestershire sauce
- 4 tbsp butter
- 1 tbsp all-purpose flour
- 2 lbs, peeled and cubed potatoes
- 1/2 cup milk
- 1 tsp divided salt
- 1/2 tsp divided black pepper
- 1 tbsp olive oil
Instructions
- Step 1: Preheat oven to 400°F. Place 2 lbs peeled and cubed potatoes into a large pot of salted water (1/2 tsp salt) and bring to a boil. Cook for 15-20 minutes until tender. Drain well.
- Step 2: While potatoes cook, heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1 diced medium onion, 1 diced large carrot, and 2 minced garlic cloves, sautéing for 5 minutes until softened and fragrant.
- Step 3: Add 1 lb ground beef to the skillet and cook for 6-8 minutes, breaking it up with a spoon, until browned and no longer pink.
- Step 4: Stir in 2 tbsp tomato paste, 1 tbsp Worcestershire sauce, 1 cup beef broth, and 1 cup frozen peas. Sprinkle 1 tbsp all-purpose flour over the mixture and stir well to thicken. Simmer for 5 minutes until sauce thickens and coats the beef mixture. Season with 1/2 tsp salt and 1/4 tsp black pepper.
- Step 5: Mash the drained potatoes with 4 tbsp butter, 1/2 cup milk, 1/2 tsp salt, and 1/4 tsp black pepper until smooth and creamy.
- Step 6: Transfer the beef mixture into a 9x9-inch baking dish, spreading evenly. Top with the mashed potatoes, smoothing the surface with a spatula.
- Step 7: Bake uncovered for 20 minutes until the edges bubble and the mashed potato topping is lightly golden. Let rest for 5 minutes before serving.
