- Prepare Slow Cooker: Grease the slow cooker with butter or oil to prevent sticking.
- Add Ingredients: Layer the cubed steak and diced potatoes in the slow cooker. Add diced onions if using.
- Mix Sauce: In a small bowl, combine cream of mushroom soup and milk. Pour over the steak and potatoes. Season with salt and pepper.
- Cook: Cover and cook on LOW for 6–7 hours or on HIGH for 3–4 hours, until potatoes and steak are tender.
- Add Cheese: About 15 minutes before serving, sprinkle shredded cheddar cheese over the top and cover until melted.
- Serve: Stir gently to combine or serve in layers. Garnish with fresh herbs if desired.
Cooking low and slow allows the flavors to meld and ensures the steak is tender while the potatoes absorb the creamy sauce.
Serving and Storage
Serve this casserole hot, straight from the slow cooker. It pairs well with steamed green beans, a fresh salad, or crusty bread to soak up the sauce.
Storing Leftovers
- Refrigeration: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave or on the stovetop until warmed through.
- Freezing: Cool completely and freeze in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
Tips
- Uniform Cubes: Cut steak and potatoes into similar-sized cubes for even cooking.
- Cheese Choice: Cheddar is classic, but try a sharp or smoked variety for extra flavor.
- Layering: Place potatoes on the bottom as they take slightly longer to cook than steak.
- Make Ahead: Assemble in the slow cooker the night before and refrigerate. Cook the next day as directed.
- Optional Add-Ins: Carrots, peas, or mushrooms can be added for more texture and nutrition.
