This easy to prep casserole is perfect for family dinners on busy weeknights or any day of the week!


  • 1 tablespoon vegetable oil
  • 1 pound ground beef  
  • 1 medium onion, diced 
  • 2 cloves garlic, finely chopped
  • 2 cups frozen mixed vegetables
  • 1 tablespoon tomato paste  
  • 1 tablespoon Worcestershire sauce 
  • 1/2 teaspoon salt
  • 1/4 teaspoon ground black pepper
  • 1 (10.5 ounce) can condensed cream of mushroom soup 
  • 3 cups cheddar cheese, shredded
  • 1 (24 ounce) package frozen tater tots (3 cups), not thawed


  1. Preheat oven to 375F.
  2. Heat oil in a large skillet over medium-high heat for 1 minute. Add ground beef and cook until browned evenly, about 5-7 minutes. Use a spatula to break the beef into small pieces to help with even browning. 
  3. Add onion and garlic and sauté until tender, about 2 minutes. 
  4. Add frozen vegetables, tomato paste, and Worcestershire sauce and stir until well combined. Season with salt and pepper.
  5. Transfer the beef mixture to a 3 quart oval/round baking dish (or 9x13-inch casserole dish) and spread evenly. If you are using an oven-safe skillet then skip this step as you can bake with the same skillet.
  6. Pour the condensed mushroom soup evenly over the beef mixture. Add a layer of cheddar cheese and a final layer of tater tots arranged symmetrically and evenly on top.
  7. Bake for 40-45 minutes until golden brown and cheese has melted completely and sauce is bubbly. Allow the casserole to rest for 5 minutes and serve warm.


How to store: Once the tater tot casserole has cooled completely, cover the pan tightly with plastic cling wrap or transfer leftovers to an airtight container and refrigerate for up to 5 days.

How to reheat: Reheat leftovers in the oven at 350℉ for 20-30 minutes or until warmed through.

How to freeze: Transfer to a freezer-safe container and wrap tightly in plastic cling wrap and a layer of aluminum foil before freezing for up to 3 months. Allow it to thaw in the refrigerator overnight before reheating and serving.
