Ingredients You’ll Need

The beauty of Slow Cooker Steak and Cheddar Potato Casserole is in its simple, familiar ingredients that transform into something extraordinary. Each component plays a crucial role, layering flavors and textures that meld perfectly as they cook together. Grab these basics, and let your slow cooker do the rest!

Sirloin or Ribeye Steak (1 ½ lbs, cubed): Marbled, flavorful steak holds up well during slow cooking, ensuring juicy, melt-in-your-mouth bites.
Russet or Yukon Gold Potatoes (4 large, thinly sliced): These potatoes are starchy and buttery, creating a perfectly tender foundation for your casserole.
Sharp Cheddar Cheese (2 cups, freshly grated): Freshly grated cheddar melts better, adding creaminess and a sharp, tangy richness.
Heavy Cream (1 cup): For an extra layer of indulgence and silky-smooth sauce.
Beef Broth (1 cup): Adds depth and umami, marrying the steak and potatoes together into a cohesive dish.
Onion (1 medium, finely diced): The sweet aroma and flavor boost every layer.
Garlic (2 cloves, minced): Infuses the casserole with savoriness you can’t resist.
Butter (2 tbsp): Used to sear the steak, locking in juices and flavor from the very first step.
Smoked Paprika: Just a sprinkle takes things up a notch with subtle smoky warmth.
Black Pepper: A few cracks for gentle heat and aromatic goodness; adjust to taste.
Salt: To season each component perfectly and make those flavors shine.

How to Make Slow Cooker Steak and Cheddar Potato Casserole

Step 1: Sear the Steak for Big Flavor

Start with a hot skillet and melt butter over medium-high heat. Once the butter sizzles, add your cubed steak, season generously with salt, pepper, and smoked paprika, and sear until every side is beautifully caramelized. This step locks in juices, builds amazing flavor, and sets the stage for the most irresistible Slow Cooker Steak and Cheddar Potato Casserole.

Step 2: Layer Potatoes, Onion, and Garlic

In your slow cooker, build the base layer by spreading half of the thinly sliced potatoes evenly. Scatter half the diced onion and minced garlic over the potatoes, letting those flavors mingle and infuse into every bite. These layers are the soul of your casserole!

Step 3: Add the Steak and Finish Layering

Transfer your seared steak (along with any pan juices) over the first potato layer. Next, add the rest of your potatoes, onion, and garlic, creating deliciously even layers so nothing gets left behind.

Step 4: Pour in Cream and Broth

Whisk together beef broth and heavy cream, then pour this rich mixture over everything in the slow cooker. Give it an extra sprinkle of salt and pepper if you love bolder flavor. The sauce will transform into something ultra-creamy as it cooks.

Step 5: Top with Cheddar and Slow Cook

Cover the top with a generous layer of freshly grated sharp cheddar cheese—it’ll melt into magical pockets of gooey deliciousness. Put the lid on, set your slow cooker to low for 6-8 hours or high for about 3-4 hours, and let those flavors work their slow-cooked magic until the potatoes are fork-tender and the steak is succulent.

How to Serve Slow Cooker Steak and Cheddar Potato Casserole

Garnishes

Finish your Slow Cooker Steak and Cheddar Potato Casserole with a sprinkle of chopped fresh parsley or chives for a pop of color and a little herbal lift. A pinch of extra smoked paprika or a swirl of sour cream adds another layer of flavor—and makes the casserole look as wonderful as it tastes.

Side Dishes

Pair this rich, cheesy casserole with something bright and crisp, like a simple green salad tossed in lemony vinaigrette or steamed seasonal vegetables. Fluffy dinner rolls or crusty bread are also perfect for soaking up any extra sauce left on your plate.

Creative Ways to Present

For a dinner party twist, spoon portions of Slow Cooker Steak and Cheddar Potato Casserole into individual ramekins and sprinkle with extra cheddar. Or, serve family-style straight from the crock, letting everyone dig in for a true comfort food experience. Leftovers make fantastic hearty wraps or can be transformed into next-day breakfast hash!

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer any leftover Slow Cooker Steak and Cheddar Potato Casserole into airtight containers. Store in the fridge for up to 4 days—the flavors just keep getting better, and you’ll thank yourself for those easy-to-grab lunches or quick dinners all week.

Freezing

Want to save some for later? This casserole freezes beautifully. Divide into single or family-sized portions, wrap well or use freezer-safe containers, and store for up to 2 months. Just make sure to cool it completely before freezing to preserve texture and flavor.

Reheating

Reheat individual servings in the microwave, loosely covered, until steaming hot. For larger portions, pop the casserole in the oven at 350°F, covered with foil, until heated through. If it looks a bit dry, add a splash of broth or cream before reheating to revive that luscious, creamy texture.

FAQs

Can I use a different cut of steak?

Absolutely! While sirloin and ribeye are fantastic for tenderness and flavor, you can also try stew beef or even leftover roast. Just keep in mind that leaner cuts might not be quite as juicy after slow cooking.

Do I need to peel the potatoes?

That’s totally up to you. Yukon Gold and red potatoes have tender skins that add rustic texture and extra nutrients, but you can peel them for a smoother, more classic casserole if you prefer.

Can I assemble this dish the night before?

You can! Layer everything except the cheese and liquids in your slow cooker insert, cover, and refrigerate overnight. In the morning, pour in the broth, cream, and top with cheese before starting the slow cooker for fresh, easy meal prep.

What other cheeses work well in this casserole?

Try mixing in some Monterey Jack, Gruyere, or mozzarella for different flavor profiles. Just be sure to use freshly grated cheese rather than pre-shredded for the creamiest melt.

How do I know when it’s done?

Your Slow Cooker Steak and Cheddar Potato Casserole is ready when the potatoes are fork-tender and the steak is cooked to your liking. Typically, after 6-8 hours on low, you’ll have a bubbly, cohesive casserole that holds its shape perfectly for serving.
