Step 1 – Cook the Beef
In a large skillet, heat olive oil or butter over medium heat. Add the ground beef, diced onion, and minced garlic.
Cook until the beef is browned and the onions are soft. Drain excess fat and season with smoked paprika, garlic powder, onion powder, salt, and black pepper.
Step 2 – Make the Sauce
In a medium bowl, whisk together the cream of mushroom soup, sour cream, and milk until smooth. Set aside.
Step 3 – Assemble in Slow Cooker
Lightly grease the slow cooker with cooking spray or butter. Layer half of the thinly sliced potatoes on the bottom.
Spread half of the cooked beef mixture over the potatoes, then pour a portion of the sauce evenly on top. Sprinkle with a portion of the cheddar cheese.
Repeat layers with the remaining potatoes, beef, sauce, and cheeses, finishing with cheddar (and mozzarella if using) on top.
Step 4 – Cook
Cover and cook on Low for 6–7 hours or on High for 3–4 hours, until the potatoes are tender and the casserole is hot and bubbly.
Garnish with chopped fresh parsley before serving.
Serving and Storage:
Serve hot as a main dish. This casserole pairs wonderfully with a crisp green salad or roasted vegetables.

Tips:
- Slice potatoes thinly and evenly to ensure they cook thoroughly.
- For extra flavor, add a pinch of smoked paprika or fresh herbs to the layers.
- Use a combination of cheddar and mozzarella for gooey, melty texture.
- Drain excess grease from the beef to prevent the casserole from becoming too oily.
