Ingredients You’ll Need

For the Beef Layer:

  • 1 lb ground beef
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 tablespoon tomato paste
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon paprika (optional)
  • 1/2 cup beef broth

For the Mashed Potato Layer:

  • 4 large potatoes, peeled and cut into chunks
  • 1/4 cup milk (adjust as needed for creaminess)
  • 3 tablespoons butter
  • Salt and pepper, to taste

For the Cheese Topping:

  • 1 1/2 cups shredded cheddar cheese (or your preferred cheese)

Step-by-Step Instructions

1. Make the Beef Layer

In a large skillet over medium heat, cook the ground beef until browned, breaking it up with a spoon as it cooks. Drain any excess fat, then add the chopped onion and minced garlic, cooking until the onion is soft and fragrant. Stir in the tomato paste, Worcestershire sauce, salt, black pepper, and paprika. Mix everything well, then add the beef broth to keep the mixture moist and simmer for about 5 minutes until thickened. Remove from heat and set aside.

2. Prepare the Mashed Potatoes

While the beef is cooking, bring a pot of salted water to a boil and add the peeled, chopped potatoes. Boil for 15-20 minutes or until they’re fork-tender. Drain the potatoes and return them to the pot. Add the butter, milk, salt, and pepper, then mash until smooth and creamy. Adjust the milk for desired consistency and seasoning if needed.

3. Assemble the Casserole

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and spread the beef mixture evenly across the bottom. Next, layer the mashed potatoes over the beef, spreading it out evenly with a spatula. Finally, sprinkle the shredded cheddar cheese generously over the top.

4. Bake

Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is bubbly and golden brown. For an extra crispy top, broil for an additional 2-3 minutes, keeping a close eye to prevent burning.

5. Cool and Serve

Allow the casserole to cool for about 5 minutes before serving. This lets the layers set a bit and makes it easier to slice. Serve hot and enjoy!

Tips for the Best Cheesy Beef and Mashed Potato Bake

  1. Perfect Mashed Potatoes: Use starchy potatoes like russets for fluffy, creamy mashed potatoes. Avoid over-mashing, as this can make them gluey.
  2. Season Generously: Don’t skimp on seasoning in either the beef layer or the mashed potatoes. The Worcestershire sauce adds depth to the beef, while salt and pepper bring out the flavors in the potatoes.
  3. Adding Vegetables: To make this a full meal, consider mixing in cooked vegetables like carrots, peas, or corn with the beef. These add color, flavor, and nutrition to the dish.
  4. Choose Your Cheese: Cheddar adds a sharp, rich flavor, but you can use mozzarella for a milder taste or pepper jack for a hint of spice. Use your favorite cheese or a blend for even more flavor.
  5. Freezing and Reheating: This casserole freezes well and is ideal for meal prepping. Allow it to cool completely, then cover tightly with plastic wrap and foil before freezing. To reheat, thaw overnight in the fridge, then bake at 350°F (175°C) until heated through.

Variations to Try

The beauty of this Cheesy Beef and Mashed Potato Bake is that it’s incredibly versatile. Here are a few variations to try:

  • Mexican-Style Casserole: Add taco seasoning to the beef and top with a blend of cheddar and Monterey jack cheese. Serve with salsa and sour cream on the side.
  • Italian Twist: Use Italian seasoning and add a layer of marinara sauce with the beef. Top with mozzarella cheese for a lasagna-inspired bake.
  • Loaded Baked Potato Style: Add cooked bacon bits, chives, and a sprinkle of Parmesan cheese to the mashed potato layer for a loaded flavor.

Serving Suggestions

Cheesy Beef and Mashed Potato Bake is a hearty dish that pairs well with light, refreshing sides. Consider serving it with a crisp green salad, steamed broccoli, or roasted vegetables to balance out the richness of the casserole. A slice of garlic bread or a warm dinner roll also makes a wonderful addition.
