Ingredients

Vegetables & Protein

  • 2 pounds russet potatoes (peeled & diced)
  • 1 pound lean ground beef
  • 1 medium onion (chopped)
  • 4 cloves garlic (minced)
  • 1 cup frozen mixed vegetables

Seasonings & Sauces

  • Salt & pepper (to taste)
  • 1 tablespoon soy sauce
  • 1 teaspoon Italian seasoning

Dairy & Canned

  • 1 (10.5 ounce) can condensed cream of mushroom soup
  • 1 cup milk (2% recommended)
  • 1/2 cup sour cream
  • 2 cups shredded cheddar cheese (divided)


Instructions

  1. Preheat Oven: Preheat your oven to 400°F and position the oven rack to the middle.
  2. Prepare Potatoes: Add the peeled and diced potatoes to a greased 9×13-inch casserole dish, spreading them evenly.
  3. Cook Ground Beef and Onions: In a skillet over medium heat, add the ground beef and chopped onion. Cook while breaking up the meat until browned, about 8-10 minutes. Drain excess fat if necessary.
  4. Add Garlic and Vegetables: To the skillet, add the minced garlic and frozen mixed vegetables. Cook for another 2-3 minutes, stirring frequently. Season with salt and pepper to taste, then transfer the mixture to the casserole dish over the potatoes.
  5. Make Sauce: In a medium bowl, combine the condensed cream of mushroom soup, milk, sour cream, soy sauce, Italian seasoning, and half of the shredded cheddar cheese. Mix thoroughly.
  6. Combine and Layer: Pour the sauce mixture over the beef and potato mixture in the casserole dish. Stir gently to combine and arrange everything into an even layer.
  7. Bake Covered: Cover the casserole tightly with aluminum foil and bake for 45 minutes in the preheated oven.
  8. Add Cheese and Bake Uncovered: Remove the foil and sprinkle the remaining cheddar cheese evenly on top. Bake uncovered for another 10-15 minutes, or until the cheese is melted and bubbly and the potatoes are tender.
  9. Rest and Serve: Let the casserole rest for 5-10 minutes before serving. Adjust seasoning with extra salt and pepper to taste.

Notes

  • For best texture, use russet potatoes as they cook evenly and absorb flavors well.
  • Drain excess fat after browning the beef to keep the casserole from being too greasy.
  • Adjust seasoning gradually—start with less salt since the cream of mushroom soup and soy sauce add sodium.
  • If you prefer a spicier dish, consider adding a pinch of cayenne pepper or smoked paprika.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
