Ingredients
Method
- Preheat oven to 400°F. Heat oil in a large oven-safe skillet over medium-high. Add beef and onion; cook 5 minutes until browned. Drain fat.
- Stir in garlic, taco seasoning, and a pinch of salt. Add salsa, bring to a simmer, and cook 2 minutes.
- Remove skillet from heat. Arrange sliced potatoes in a single overlapping layer over the beef. Sprinkle lightly with salt.
- Cover tightly with foil and bake 35 minutes.
- Remove foil, sprinkle cheese evenly over potatoes, and bake uncovered 10 to 15 minutes until cheese is bubbly and golden in spots.
- Let the casserole rest 5 minutes. Top with sour cream and cilantro, then serve from the skillet.
Notes
If you only have a baking dish, brown the beef in a regular pan and layer everything into a greased 9×13 dish before baking. The 5-minute rest after baking makes a real difference in how neatly the casserole portions. Use hot salsa or add a chopped jalapeño to the beef if your crowd likes spice.
