Recipe Information
Ingredients
- 2 pounds Ground beef
- 1 large Yellow onion
- 3 cloves Garlic cloves
- 2 tablespoons Vegetable oil
- 1.5 teaspoons Salt
- 1 teaspoon Ground black pepper
- 2 tablespoons Worcestershire sauce
- 3 tablespoons Tomato paste
- 2 cups Frozen mixed vegetables (corn, peas, carrots)
- 4 large Russet potatoes
- 4 tablespoons Unsalted butter
- 0.5 cup Whole milk
- 2 cups Shredded cheddar cheese
- 0.5 teaspoons Paprika
Instructions
Preheat your oven to 375°F (190°C).
Peel and roughly chop the russet potatoes. Place them in a large pot of salted water and bring to a boil. Reduce heat to a simmer and cook until tender, about 15–20 minutes.
While the potatoes are cooking, heat the vegetable oil in a large skillet over medium-high heat. Add the diced onion and cook until softened, about 5 minutes.
Stir in the minced garlic and cook for another minute.
Add the ground beef to the skillet, breaking it up with a wooden spoon. Cook until browned and no longer pink, about 7–8 minutes.
Drain any excess grease from the skillet, then stir in salt, black pepper, Worcestershire sauce, and tomato paste. Mix well to combine.
Add the frozen mixed vegetables to the skillet, stir, and cook for another 5 minutes until the vegetables are warmed through. Remove from heat and set aside.
Once the potatoes are tender, drain them and return them to the pot. Add the butter and milk, then mash until smooth. Season with additional salt to taste, if necessary.
In a large casserole dish (approximately 9x13 inches), spread the beef and vegetable mixture evenly across the bottom.
Layer the mashed potatoes over the beef mixture, spreading them evenly with a spatula.
Sprinkle the shredded cheddar cheese evenly over the mashed potatoes.
Dust the top with paprika for color and flavor.
Transfer the casserole dish to the preheated oven. Bake for 30 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
Remove the casserole from the oven and let it rest for 5 minutes before serving. Enjoy!
