1-First Step: Start by cooking 2 pounds of ground beef in a skillet over medium heat until it’s no longer pink, which takes about 6-8 minutes; drain the excess fat to keep the mixture from becoming too greasy, and for dietary adaptations, swap in plant-based mince if making a vegan version.

2-Second Step: In a large bowl, combine 1 can (10 3/4 ounces) of condensed cream of mushroom soup, 1 can (10 3/4 ounces) of condensed cream of chicken soup, 1 teaspoon of dried onion flakes, and 1/4 teaspoon of black pepper; stir well to create a smooth base, and use dairy-free alternatives here for vegan adaptations to maintain that creamy texture in your beef potato bake.

3-Third Step: Add 1 package (32 ounces) of thawed frozen potatoes, 2 cups of shredded cheddar cheese, and 1 can (8 ounces) of drained sliced mushrooms to the soup mixture; mix everything thoroughly, then incorporate the cooked ground beef for even distribution, adjusting with gluten-free options if needed to ensure the creamy beef potato casserole suits all diets.

4-Fourth Step: Transfer the mixture into two greased 8-inch square baking dishes, then sprinkle each with 1 cup of the remaining shredded cheddar cheese; at this point, cover one dish and freeze it for up to 3 months, while preparing the other for immediate baking at 375 degrees Fahrenheit for 45 to 50 minutes, or until potatoes are tender check doneness by inserting a fork.

5-Final Step: After the initial bake, uncover and bake for an additional 5 to 10 minutes until the cheese melts and turns golden; for the frozen casserole, thaw in the refrigerator overnight, let it sit out for 30 minutes, then bake as directed, adding a splash of broth if it seems dry to restore moisture, ensuring a perfectly creamy beef potato casserole every time. For the best results, par-cook potatoes if using fresh ones to avoid undercooked layers, and serve with a side salad for a complete meal.
