Method
Prep and preheat
- Preheat your oven to 375°F and grease a 9x13 baking dish so it doesn’t stick.
Brown the beef and aromatics
- Brown ground beef with diced onion in a skillet over medium heat until the beef is cooked through.
- Drain the fat, add minced garlic, and cook for 1 more minute until fragrant.
Make the creamy mushroom mixture
- Mix cream of mushroom soup, sour cream, beef broth, garlic powder, onion powder, smoked paprika, salt, and black pepper in a bowl until smooth.
Layer and bake covered
- Layer half the sliced potatoes in the bottom of the dish to form an even base.
- Top with half the beef mixture so the potatoes are covered in savory, crumbled layers.
- Spoon on half the soup mixture, spreading gently to help it seep between layers.
- Repeat the layers with the remaining potatoes, beef mixture, and soup mixture for a fully stacked casserole.
- Cover tightly with foil and bake for 40 minutes at 375°F, until the potatoes are tender.
Add cheese and finish baking
- Remove the foil and top with shredded sharp cheddar cheese for a thick, melty layer.
- Bake uncovered for 15 more minutes at 375°F until the cheese is golden and bubbly.
Notes
For the best texture, slice the potatoes thin and keep the foil tightly sealed during the first 40 minutes so they steam tender. Store leftovers in the refrigerator up to 3 days in a covered container; reheat in the oven or microwave until hot. Freezing is not recommended because the potatoes can turn softer after thawing. For a lighter swap, use low-fat sour cream while keeping the same layering method.
