Ingredients You’ll Need

The magic of this Slow Cooker Steak and Cheddar Potato Casserole lies in its straightforward ingredients. Each component serves a purpose, bringing bold flavor, creamy texture, or that signature cheesy finish that makes this casserole irresistible.

Sirloin or Ribeye Steak (1 ½ lbs, cubed): Pick a well-marbled cut for rich, tender bites throughout the casserole.
Russet or Yukon Gold Potatoes (4 large, thinly sliced): These potatoes hold their shape and soak up that luscious cheesy sauce perfectly.
Sharp Cheddar Cheese (2 cups, freshly grated): Freshly grated cheese melts beautifully, giving the dish its irresistible gooey topping.
Heavy Cream (1 cup): Cream adds richness that elevates the entire casserole to comfort food status.
Beef Broth (1 cup): Adds robust flavor while keeping everything deliciously moist.
Onion (1 medium, finely diced): Onion lends subtle sweetness and depth to the flavor profile.
Garlic (2 cloves, minced): Garlic infuses every layer with aromatic warmth.
Butter (2 tbsp): Used for searing the steak, it adds an extra layer of richness.
Smoked Paprika: A sprinkle of this smoky spice brings a gentle warmth that ties the entire casserole together.
Black Pepper: Freshly ground for just the right touch of heat.
Salt: Essential for brightening and enhancing all those deep, savory flavors.

How to Make Slow Cooker Steak and Cheddar Potato Casserole

Step 1: Sear the Steak

Searing isn’t just for show—it unlocks a deep, savory flavor you simply can’t get any other way! Heat your butter in a skillet over medium-high heat. Toss in the cubed steak, generously seasoned with salt, black pepper, and smoked paprika. Let the pieces sizzle and brown on all sides; this only takes a few minutes but makes all the difference. Once they’ve picked up a gorgeous golden crust, turn off the heat and set them aside.

Step 2: Layer the Potatoes, Onions, and Garlic

Building your casserole is all about layering for maximum flavor and that classic slow-cooked texture. In your slow cooker, create the first layer with half of your sliced potatoes. Scatter half of the finely diced onion and minced garlic over the potatoes. This is the foundation where all those delicious juices will settle and infuse every bite with warmth.

Step 3: Add the Steak and Second Layer

Now, it’s time to nestle in all that beautiful browned steak on top of your potato mixture. Pile on the remaining potatoes, onion, and garlic to add even more heartiness and flavor throughout the casserole. Don’t worry—these layers will gently melt together as the casserole cooks.

Step 4: Pour in Cream and Broth

The secret to a creamy, tender Slow Cooker Steak and Cheddar Potato Casserole is the liquids you add at this stage. Pour your beef broth and heavy cream evenly across the entire casserole. If you like a bit more seasoning, scatter some salt and pepper now. The slow cooker will do the rest, ensuring every piece becomes melt-in-your-mouth tender.

Step 5: Top with Cheddar and Cook

Finish strong by layering freshly grated sharp cheddar all over the top. Place the lid on your slow cooker and let the magic happen: set it to low for 6-8 hours or high for 3-4 hours. When the potatoes are fork-tender and the cheese is melted and golden, your Slow Cooker Steak and Cheddar Potato Casserole is ready to serve!

How to Serve Slow Cooker Steak and Cheddar Potato Casserole

Garnishes

Garnishing this casserole takes it from comfort food to downright irresistible. Try a sprinkle of extra sharp cheddar, fresh chives, or sliced green onions for a pop of color and freshness. A dash of extra smoked paprika (or even a touch of hot sauce) adds vibrant flavor right at the table. These little finishing touches let everyone customize their serving.

Side Dishes

This casserole is supremely satisfying on its own, but a light, crisp salad with a tangy vinaigrette makes a lovely contrast. For classic comfort, serve alongside warm, crusty bread for dunking, or a simple green vegetable like steamed broccoli or peas to round out your plate. Every side brings something new to the table and balances the rich flavors of your Slow Cooker Steak and Cheddar Potato Casserole.

Creative Ways to Present

To really make this meal party-ready, try scooping servings into individual ramekins or mini cast iron skillets for a rustic look. If you’re feeding a crowd, serve straight from the slow cooker on a buffet so everyone can help themselves. For an extra-special brunch, pair smaller portions with fried eggs or serve over warm biscuits for a twist on Southern flavors.

Make Ahead and Storage

Storing Leftovers

Got leftovers? Lucky you! Let the casserole cool completely, then transfer it to airtight containers. Store in the refrigerator where it will keep beautifully for up to 4 days. When you need an effortless dinner (or a midnight snack!) this ready-made meal is waiting.

Freezing

Slow Cooker Steak and Cheddar Potato Casserole freezes like a dream for longer storage. Simply portion cooled casserole into freezer-safe containers or tightly wrap in foil. Label and date, then freeze for up to 2 months. Thaw overnight in the refrigerator before reheating for best results.

Reheating

To reheat, use the oven to bring back those crispy cheesy edges—just cover and warm at 350°F until heated through. The microwave works too for single servings (about 2-3 minutes, depending on your microwave). Add a splash of beef broth or cream if you want to revive that original creamy texture.

FAQs

Can I use a different type of steak?

Absolutely! Sirloin and ribeye are classic, but other tender cuts like strip steak or even flat iron steak will work well. Just avoid tougher cuts unless you’re ready for a longer cook.

Can I prep everything the night before?

You sure can! Slice your potatoes and onions, sear the steak, and assemble all the layers right in your slow cooker insert. Cover tightly and refrigerate overnight, then start cooking in the morning.

Will pre-shredded cheese work?

While it’s convenient, freshly grated cheddar melts much smoother and gives the casserole its signature oozy texture. Pre-shredded often contains anti-caking agents that can affect the final result.

How can I make this casserole spicier?

To dial up the heat, add a pinch of cayenne to the steak seasoning, splash in a bit of hot sauce, or throw some chopped jalapeños into the potato layers. The casserole welcomes bold flavors!

Is it possible to make Slow Cooker Steak and Cheddar Potato Casserole vegetarian?

Yes—swap out the steak for hearty mushrooms or your favorite meat substitute, and use vegetable broth instead of beef broth. The creamy, cheesy potato goodness will still shine.

Final Thoughts

There’s just something magical about the way Slow Cooker Steak and Cheddar Potato Casserole brings people together around the table. Every bite is a celebration of savory steak, creamy potatoes, and golden cheddar. Whether you’re cooking for family or treating yourself, this casserole is a guaranteed hit—give it a try, and it may just become a new favorite in your rotation!
