Ingredients
Method
- Prep the oven: Preheat oven to 350°F (175°C). Grease a 9x13 inch baking dish with butter or cooking spray.
- Cook the beef: In a large skillet over medium-high heat, brown the ground beef, breaking it up as it cooks (about 5-6 minutes). Add diced onion and cook until softened, about 5 minutes more. Stir in minced garlic, paprika, and thyme. Season with salt and pepper. Remove from heat.
- Make the sauce: In a small bowl, whisk together the cream of mushroom soup and milk until smooth and well combined.
- First layer: Arrange half of the sliced potatoes in the prepared baking dish, overlapping slightly. Season with salt and pepper.
- Add beef layer: Spread half of the cooked beef mixture evenly over the potatoes.
- Add sauce: Drizzle half of the soup mixture over the beef layer.
- Repeat layers: Layer the remaining potatoes, then remaining beef mixture, and finish with the remaining soup mixture on top.
- Bake covered: Cover tightly with aluminum foil and bake for 45 minutes.
- Add cheese: Remove foil and sprinkle shredded cheese evenly over the top. Bake uncovered for another 15-20 minutes, until cheese is golden brown and potatoes are fork-tender.
- Rest and serve: Let the casserole rest for 10 minutes before serving to allow layers to set.
Notes
Potato Tips:
Slice potatoes as evenly as possible for uniform cooking.
A sharp knife works better than a mandoline for safety.
Make-Ahead: Assemble the casserole up to step 7, cover and refrigerate for up to 24 hours.
Add 10-15 extra minutes to covered baking time if cooking from cold. Storage: Leftovers keep in the refrigerator for 4 days and reheat beautifully in the microwave.
Substitutions: Ground turkey or plant-based ground meat works well.
Sweet potatoes can replace regular potatoes for a twist.
Cheese Options: Monterey Jack, Colby, or Mexican cheese blend are great alternatives to cheddar.
