4 large potatoes, diced: The hearty backbone of the casserole, offering a creamy, soft texture after baking.
1 cup beef broth: Ensures the casserole remains moist while enriching the beef flavor throughout the dish.
1 cup shredded cheddar cheese: Melts into a golden, bubbly blanket of savory goodness that finishes the casserole perfectly.

How to Make Cowboy Steak and Potato Casserole Recipe

Step 1: Brown the Beef and Sauté Aromatics

Start by preheating your oven to 375°F (190°C). Heat that olive oil in a large skillet over medium-high heat until it shimmers, then add your cubed sirloin steak. Cook the beef until it’s beautifully browned on all sides, locking in all those meaty juices. Remove the beef and set it aside. Next, use the same skillet to soften your chopped onions and garlic—this step unlocks their sweet and savory aromas, setting a flavorful base for your casserole.

Step 2: Layer the Ingredients in the Baking Dish

Grab a baking dish and start building your casserole with a layer of diced potatoes. Follow that with your browned steak, scattering it evenly to ensure every bite has meat. Add the fragrant sautéed onion and garlic over the top, then pour the beef broth gently across all. Season with salt and pepper—this simple seasoning balances the flavors perfectly. Cover the dish with foil to keep everything moist, then slide it into the oven to bake for about 45 minutes, allowing the potatoes to soften and the flavors to meld beautifully.

Step 3: Add Cheese and Finish Baking

Once your casserole has baked to tender perfection, remove the foil and sprinkle the shredded cheddar cheese evenly across the top. Return the dish to the oven uncovered, baking for another 10 to 15 minutes until that cheese melts into a golden, bubbling crust that’s irresistible. To finish, garnish with freshly chopped parsley, which adds a fresh contrast to the richness and enhances the dish’s rustic appeal.

Garnishes

While fresh parsley is the classic choice for garnishing this casserole, don’t hesitate to experiment with chopped chives or a sprinkle of smoked paprika for an extra burst of color and flavor. A dollop of sour cream can also bring a cool, creamy touch that complements the warm, cheesy casserole beautifully.

Side Dishes

This hearty casserole pairs wonderfully with crisp, refreshing sides. A simple green salad with a tangy vinaigrette helps cut through the richness, while steamed green beans or roasted asparagus add vibrant color and seasonal freshness to your plate. For a real cowboy-themed feast, consider serving with cornbread or buttery dinner rolls for soaking up every last bit of delicious juice.

Creative Ways to Present

If you’re looking to impress your guests, serve individual portions in rustic cast iron skillets or ovenproof ramekins for charming, personal servings. Alternatively, layering the steak and potato mixture in a deep pie crust before baking can transform this recipe into a savory pie for a delightful twist. Drizzling a little hot sauce or barbecue glaze on top before serving can also elevate flavors and presentation.

Make Ahead and Storage

Storing Leftovers

This Cowboy Steak and Potato Casserole Recipe makes plenty of leftovers that are just as delicious the next day. Store any uneaten portions in an airtight container in the refrigerator, where they’ll stay fresh for up to 3 days. Make sure to cool the casserole completely before storing to maintain quality and flavor.

Freezing

You can freeze this casserole for longer storage by placing it in a freezer-safe container or tightly wrapped with foil and plastic wrap. Freeze for up to 2 months, and when you’re ready to enjoy it again, thaw it overnight in the refrigerator before reheating to keep that tender steak and creamy potato texture intact.

Reheating

Reheat leftovers by covering the casserole with foil to prevent drying out and baking in a 350°F (175°C) oven for about 20-25 minutes until warmed through. For individual servings, microwaving on medium power works well, just be careful not to overcook so the beef stays juicy and the cheese remains melty.

FAQs

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

Absolutely! While sirloin is ideal for its tenderness and flavor, you can use other cuts like ribeye or flank steak. Just be sure to cut the meat into bite-sized cubes and brown it well to lock in juices.

Are there alternatives to cheddar cheese that work well here?

Yes! A sharp Monterey Jack, smoked gouda, or even a blend of mozzarella and parmesan can add unique flavors and excellent melting qualities. Feel free to experiment based on your taste preferences.

Can I make this casserole vegetarian?

While this Cowboy Steak and Potato Casserole Recipe is meat-focused, you can create a vegetarian version by replacing steak with hearty mushrooms or plant-based meat substitutes and using vegetable broth instead of beef broth. The casserole will still be deliciously hearty.

Is it possible to prepare this recipe in a slow cooker?

Yes, you can adapt this dish for a slow cooker by browning the beef and sautéing the onions and garlic first, then layering everything in the slow cooker and cooking on low for 6-8 hours. Just add the cheese in the last 15 minutes of cooking.

What can I serve this casserole with for a complete meal?

To round out your meal, pair it with a fresh green salad, steamed vegetables, or roasted root vegetables. A crusty bread or warm cornbread also complements the richness perfectly.
