Ingredients
- 1 pound ground beef
- 2 tablespoons olive oil
- 1 medium, diced onion
- 2 medium, diced carrot
- 1 cup frozen peas
- 1 cup beef broth
- 2 tablespoons tomato paste
- 1 tablespoon Worcestershire sauce
- 1 teaspoon, divided salt
- 1/2 teaspoon, divided black pepper
- 2 pounds, peeled and quartered potatoes
- 4 tablespoons unsalted butter
- 1/2 cup whole milk
- 3, minced garlic cloves
Instructions
- Step 1: Preheat oven to 400°F. Heat 2 tablespoons olive oil in a large skillet over medium heat. Add 1 diced medium onion and 2 diced medium carrots; sauté for 5 minutes until softened.
- Step 2: Add 1 pound ground beef to the skillet and cook for 6-7 minutes, breaking it up with a spoon until browned and no pink remains. Season with 1/2 teaspoon salt and 1/4 teaspoon black pepper.
- Step 3: Stir in 2 tablespoons tomato paste, 1 cup beef broth, 1 cup frozen peas, and 1 tablespoon Worcestershire sauce. Simmer for 10 minutes until the mixture thickens slightly.
- Step 4: Meanwhile, place 2 pounds peeled and quartered potatoes in a large pot of salted water. Bring to a boil and cook for 15-18 minutes until very tender.
- Step 5: Drain the potatoes and return to pot. Add 4 tablespoons unsalted butter, 1/2 cup whole milk, 3 minced garlic cloves, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Mash until smooth and creamy.
- Step 6: Transfer the beef mixture to a 9x13-inch baking dish and evenly spread the mashed potatoes on top. Use a fork to create texture on the potatoes.
- Step 7: Bake in the preheated oven for 20-25 minutes until the top is lightly golden and edges are bubbling. Let rest 5 minutes before serving.
