Easy homemade tater tot casserole (no cream of soup!) with loads of veggies, lean ground beef and crispy tater tots.


  • 3 tablespoons oil or butter
  • ½ medium onion, peeled and diced
  • 1-pound lean ground beef
  • 12-ounce bag frozen mixed vegetables
  • 1 ½ teaspoons kosher or sea salt
  • 1 teaspoon dried mustard powder
  • ½ teaspoon each celery salt, onion powder and garlic powder
  • ½ teaspoon ground black pepper
  • 4 tablespoons all-purpose flour
  • 2 cups unsalted beef stock
  • Dash Worcestershire sauce (optional)
  • ½ cup shredded cheddar cheese
  • ~70-75 frozen tater tots (from a 32-ounce bag)


  1. Preheat the oven to 375 degrees.
  2. Heat the oil or butter in a large stove-top casserole dish or large oven-safe skillet to medium. Add the onion and sauté 4-5 minutes or until soft. Add the ground beef and cook another 5-7 minutes or until browned, breaking up the pieces with a wooden spoon as it cooks. Stir in the mixed vegetables and sauté another 2-3 minutes. Stir in the salt, mustard powder, celery salt, onion powder, garlic powder and black pepper.
  3. Stir in the flour until incorporated. Increase the heat to medium-high. Add the stock and bring to a simmer, stirring constantly for 2-3 minutes, until thickened. Taste and adjust the seasoning, if necessary. Stir in the Worcestershire sauce (if using). Remove from the heat and flatten the beef mixture in an even layer.
  4. Sprinkle the cheddar cheese in an even layer over the beef mixture. Line with tater tots. Bake 20-25 minutes or until the tater tots are golden and crispy and the filling is bubbly. Let rest for 5 minutes, then scoop and serve.


Cooking Tip: I use the Lodge cast iron casserole dish for this and many other stove-top to oven recipes. It's a lifesaver!
