Ingredients You’ll Need

Gathering your ingredients for this dish is simple, but each one plays a vital role in building layers of flavor and texture. From the tender steak to the sharp cheddar cheese, every component blends beautifully to create a casserole that’s both rich and comforting.

1 ½ lbs sirloin or ribeye steak, cubed: Choose a cut with good marbling for tender, flavorful bites after slow cooking.

4 large Russet or Yukon Gold potatoes, thinly sliced: These varieties give you a creamy, soft texture after baking while holding their shape nicely.
2 cups sharp cheddar cheese, freshly grated: Sharp cheddar adds a robust, tangy flavor and melts to a gooey, golden topping.

1 cup heavy cream: This adds richness and helps create a luscious sauce that binds the casserole perfectly.
1 cup beef broth: Deepens the savory flavor and keeps the layers juicy and tender.

1 medium onion, finely diced: Adds subtle sweetness and a bit of crunch that caramelizes gently during cooking.
2 cloves garlic, minced: A punch of aromatic flavor that elevates the whole dish without overpowering.
2 tbsp butter: Essential for searing the steak and adding a silky richness.

Smoked paprika: Gives a mild smoky warmth that pairs beautifully with the beef and cheese.
Black pepper: Freshly ground for a little kick.
Salt: Enhances all the natural flavors and balances the dish.

How to Make Slow Cooker Steak and Cheddar Potato Casserole

Step 1: Sear the Steak

Start by heating butter in a skillet over medium-high heat. Season your cubed steak generously with salt, pepper, and smoked paprika. Then, sear the steak cubes until they’re beautifully browned on all sides. This quick step locks in those savory juices and builds an amazing base of flavor for your casserole.

Step 2: Layer the Ingredients

Now it’s time to build your casserole in the slow cooker. Lay down half of the thinly sliced potatoes first—it’s like the soft mattress that will soak up all the delicious juices. Add half of the diced onion and minced garlic right on top, bringing sweetness and aroma. Place the seared steak cubes over this, then finish layering with the remaining potatoes, onion, and garlic. This layering keeps each bite full of flavor and texture.

Step 3: Add the Liquids

Pour in the beef broth and heavy cream evenly over the layers to create a rich and creamy sauce that makes the casserole wonderfully moist and savory. If you like, sprinkle a little more salt and pepper to taste. This mixture will slowly mingle with every ingredient as it cooks.

Step 4: Top with Cheese

Finally, cover the entire creation with freshly grated sharp cheddar cheese. This topping melts into a golden, bubbly crown that adds both flavor and a beautiful presentation to the dish.

Step 5: Slow Cook to Perfection

Cover your slow cooker and set it to low for 6 to 8 hours or high for 3 to 4 hours, depending on your schedule. The slow cooking tenderizes the steak and softens the potatoes into a creamy yet textured perfection that melts in your mouth.

How to Serve Slow Cooker Steak and Cheddar Potato Casserole

Garnishes

To elevate the Slow Cooker Steak and Cheddar Potato Casserole even further, consider fresh garnishes like finely chopped green onions or fresh parsley that add a pop of color and a hint of freshness. A dollop of sour cream can also bring a cool, tangy contrast that balances the richness wonderfully.

Side Dishes

This casserole is a hearty meal on its own, but pairing it with a crisp green salad or steamed seasonal vegetables can brighten your plate and add some crunch and color. Roasted asparagus or a simple Caesar salad complement the richness beautifully without overwhelming the main dish.

Creative Ways to Present

For a fun twist, serve the Slow Cooker Steak and Cheddar Potato Casserole in individual ramekins or shallow bowls to impress guests with personal-sized portions. Alternatively, sprinkle some extra cheese and broil it for a few minutes before serving to achieve a crispy, golden crust that adds a delightful texture contrast.

Make Ahead and Storage

Storing Leftovers

Leftover Slow Cooker Steak and Cheddar Potato Casserole keeps beautifully in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making it a perfect next-day meal.

Freezing

If you want to prepare this casserole ahead of time, you can freeze it either before or after cooking. Wrap tightly in freezer-safe containers or foil and freeze for up to 2 months. Thaw overnight in the fridge before reheating to maintain best texture and flavor.

Reheating

Reheat your leftovers gently in the microwave or oven until warmed through, adding a splash of beef broth or cream if needed to loosen up the sauce. Covering with foil in the oven helps prevent the cheese topping from drying out while reheating.

FAQs

Can I use a different cut of steak for this casserole?

Absolutely! While sirloin or ribeye are ideal for tenderness and flavor, you can also use chuck or other stew beef cuts, just be sure to adjust cooking times if needed to achieve the desired tenderness.

Is it necessary to sear the steak before slow cooking?

Searing the steak develops deeper flavors and a beautiful crust, enhancing the overall taste. While you could skip this step to save time, the flavor won’t be quite as rich or complex.

Can I make this recipe dairy-free?

Yes! Substitute heavy cream with coconut cream or a plant-based heavy cream alternative, and use dairy-free cheese to keep it creamy and flavorful without dairy.

What type of potatoes work best?

Russet and Yukon Gold potatoes are the best choices due to their texture and how well they absorb flavors. Russets create a fluffier texture while Yukon Golds lend a buttery richness and hold shape nicely.

Can I add vegetables to this casserole?

Definitely! Adding mushrooms, bell peppers, or even spinach between layers can add dimension and extra nutrients without overpowering the main flavors of the Slow Cooker Steak and Cheddar Potato Casserole.
