Ingredients
- 1 lb ground beef
- 1 medium, diced yellow onion
- 2 medium, diced carrots
- 1 cup frozen peas
- 8 oz, sliced mushrooms
- 4 cloves, mashed roasted garlic cloves
- 2 lbs, peeled and cubed potatoes
- 4 tbsp, divided butter
- 1/2 cup milk
- 2 tbsp all-purpose flour
- 1 1/2 cups beef broth
- 2 tbsp tomato paste
- 1 tbsp Worcestershire sauce
- 1 tsp, divided salt
- 1/2 tsp, divided black pepper
- 2 tbsp olive oil
Instructions
- Step 1: Preheat oven to 400°F. Boil 2 lbs peeled and cubed potatoes in salted water with 1/2 tsp salt for 15-18 minutes until fork-tender. Drain and mash with 2 tbsp butter, 1/2 cup milk, and 4 mashed roasted garlic cloves until smooth and creamy.
- Step 2: While potatoes cook, heat 2 tbsp olive oil in a large skillet over medium-high heat. Add 1 diced medium yellow onion and 2 diced medium carrots, sauté for 5 minutes until softened. Add 1 lb ground beef, season with 1/2 tsp salt and 1/4 tsp black pepper, cook for 6-7 minutes breaking up meat until browned.
- Step 3: Stir in 8 oz sliced mushrooms and cook for 4 minutes until mushrooms release moisture and start to brown. Add 2 tbsp tomato paste and cook 2 minutes until fragrant.
- Step 4: Sprinkle 2 tbsp all-purpose flour over meat mixture, stir well and cook 1 minute. Slowly whisk in 1 1/2 cups beef broth, 1 tbsp Worcestershire sauce, and 1 cup frozen peas. Simmer for 5 minutes until sauce thickens and coats the back of a spoon.
- Step 5: Transfer meat and vegetable mixture to a 9x9 inch baking dish. Spread mashed potatoes evenly over the top, dotting with remaining 2 tbsp butter.
- Step 6: Bake in preheated oven for 20-25 minutes until potato crust is golden and edges are bubbling. Let rest 5 minutes before serving.
