- Paprika, 1 teaspoon: Offers warmth and a mild smoky kick.

- Olive oil, 2 tablespoons: Used to brown the steak, locking in juices.

How to Make Slow Cooker Steak and Cheddar Potato Casserole Recipe
Step 1: Brown the Steak
Start by heating olive oil in a large skillet over medium-high heat. Adding the steak pieces and browning each side seals in their natural juices and creates a rich, flavorful crust. This simple step elevates the whole casserole, so take your time to get a nice golden color before transferring the steak to the slow cooker.
Step 2: Sauté Onion and Garlic with Seasonings
In the same skillet, toss in chopped onion and minced garlic. Cooking them until the onion turns translucent brings out a lovely sweetness that balances the robust beef. Stir in Worcestershire sauce, paprika, salt, and black pepper to build a seasoning base that will permeate the entire casserole.
Step 3: Combine Onion Mixture with Steak
Transfer this aromatic onion and garlic mixture directly into the slow cooker over the browned steak. This layer adds flavor complexity and ensures every bite bursts with savory goodness.
Step 4: Pour in Creamy Broth Mixture
Whisk beef broth and heavy cream together in a bowl until fully combined. Pour this creamy liquid over the steak and onions in the slow cooker—it’s what makes the casserole irresistibly moist and succulent after hours of cooking.
Step 5: Layer the Potatoes
Next, carefully layer the thinly sliced russet potatoes on top of the liquid and meat mixture. The potatoes slowly absorb all the rich flavors and become irresistibly tender as they cook.
Step 6: Slow Cook Until Tender
Cover the slow cooker and let everything cook low and slow for 6 to 8 hours, or on high for 3 to 4 hours. This time is crucial for tenderizing the steak and softening the potatoes to just the right melt-in-your-mouth texture.
Step 7: Thicken the Sauce
About 30 minutes before the cooking time ends, mix cornstarch with water to form a smooth slurry. Stir it gently into the slow cooker. This step thickens the sauce just enough to coat every bite without being gloopy.
Step 8: Add the Cheese
Sprinkle shredded sharp cheddar evenly over the top of the potatoes. Cover the slow cooker again and let the cheese melt for 10-15 minutes until it’s gooey and golden—an essential crowning touch that makes this recipe truly special.
Step 9: Rest Before Serving
When the cheese has melted, turn the slow cooker off and let the casserole sit for about 5 minutes. This brief rest helps the flavors to settle and makes serving easier.
Step 10: Garnish and Enjoy
Finally, sprinkle freshly chopped parsley for a burst of color and freshness. Now your Slow Cooker Steak and Cheddar Potato Casserole Recipe is ready to delight your taste buds!
How to Serve Slow Cooker Steak and Cheddar Potato Casserole Recipe

Garnishes
Fresh parsley is a classic garnish for this casserole, adding a vibrant green contrast that brightens each serving. You could also consider a light dusting of smoked paprika or sliced green onions to enhance flavor and presentation.
Side Dishes
Complement this hearty casserole with crisp green salads or steamed seasonal vegetables like broccoli or green beans. A crusty loaf of bread or garlic rolls are also fantastic for soaking up any leftover sauce.
Creative Ways to Present
For a fun twist, try serving portions in individual oven-safe ramekins for a personalized touch. Alternatively, layer the casserole in a clear glass dish before cooking so your guests can admire the beautiful layers through the sides before digging in.
Make Ahead and Storage
Storing Leftovers
Place any leftover casserole in an airtight container and store it in the refrigerator for up to 3 to 4 days. Reheated portions taste just as comforting, making it perfect for next-day meals.
Freezing
This Slow Cooker Steak and Cheddar Potato Casserole Recipe freezes wonderfully. Wrap it tightly in plastic wrap and aluminum foil, or store in a freezer-safe dish for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating
Warm leftovers in the oven at 350°F (175°C) for about 20-25 minutes until heated through, or microwave individual servings for 2-3 minutes. Add a sprinkle of extra cheddar cheese on top during reheating for an indulgent touch.
FAQs
Can I use a different cut of beef for this casserole?
Absolutely! While steak pieces are recommended for tenderness, chuck roast or stew meat can also be used. Just allow for longer cooking times to get them tender.
Is it necessary to peel the potatoes?
Peeling the potatoes helps create a creamier texture and more uniform layers, but if you prefer the rustic look and a bit of extra fiber, leaving the skins on is fine too.
Can I prepare the casserole the night before?
Yes, you can assemble everything in the slow cooker insert and refrigerate overnight. Just add extra cooking time when you start slow cooking to ensure the steak and potatoes become perfectly tender.
What can I substitute for heavy cream?
If you want a lighter option, you can use whole milk combined with a tablespoon of butter or half-and-half, but this will slightly alter the richness and texture.
Can I use pre-shredded cheddar cheese?
Pre-shredded cheese works perfectly and saves time. Just make sure to choose a good quality sharp cheddar for the best flavor and melt.
