  • Total Time: 1 hour 30 minutes
  • Yield: 8 servings

Ingredients

Main Ingredients

  • 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 Worcestershire sauce
  • 1 teaspoon Italian seasoning

Other Ingredients

  • 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 the Oven: Preheat your oven to 400°F and position the oven rack in the middle to ensure even baking.
  2. Prepare Potatoes: Add the peeled and diced russet potatoes to a greased 9×13 inch casserole dish, spreading them evenly as the base layer.
  3. Cook Ground Beef and Onions: In a skillet over medium heat, add the ground beef and chopped onions. Cook while breaking up the meat with a spoon until the beef is browned and cooked through, about 8-10 minutes. Drain any excess fat to keep the dish lean.
  4. Sauté Garlic and Vegetables: To the skillet, add the minced garlic and frozen mixed vegetables. Continue cooking for 2-3 minutes, stirring frequently to combine flavors. Season with salt and pepper to taste. Then transfer this mixture over the potatoes in the casserole dish.
  5. Mix the Sauce: In a medium-sized bowl, combine the condensed cream of mushroom soup, milk, sour cream, Worcestershire sauce, Italian seasoning, and half (1 cup) of the shredded cheddar cheese. Stir well until the sauce is smooth.
  6. Combine and Layer: Pour the creamy sauce mixture evenly over the beef, vegetables, and potatoes in the casserole dish. Stir gently to incorporate everything, then spread the mixture into an even layer.
  7. Bake Covered: Cover the casserole tightly with aluminum foil and bake in the preheated oven for 45 minutes. This allows the potatoes to cook through and flavors to meld.
  8. Add Remaining Cheese and Finish Baking: Remove the foil, sprinkle the remaining cheddar cheese (1 cup) evenly over the top, and bake uncovered for an additional 10-15 minutes or until the cheese is melted and bubbly and the potatoes are tender when pierced with a fork.
  9. Rest and Serve: Remove the casserole from the oven and let it sit for 5-10 minutes to set. Taste and add extra salt and pepper if needed before serving warm.

Notes

  • Use peeled and diced russet potatoes for best texture and flavor.
  • Drain excess fat from the cooked ground beef to reduce greasiness.
  • Season to taste at multiple stages: after cooking vegetables and final before serving.
  • You can substitute cream of mushroom soup with cream of celery or chicken soup for variation.
  • This dish can be prepared a day ahead; just cool, cover, and refrigerate before baking.
