Ingredients You’ll Need
The beauty of Cowboy Steak and Potato Casserole lies in its straightforward, down-to-earth ingredients. Each one plays a starring role, whether it’s adding savory depth, vibrant color, or creamy indulgence. Here’s what you’ll need—and why each element matters so much.
- Sirloin or Flank Steak (1 1/2 pounds): Cut into bite-sized pieces, this is the hero of the dish—tender, juicy, and packed with beefy flavor.
- Olive Oil (2 tablespoons, divided): Essential for searing steak beautifully and crisping up those golden potatoes.
- Steak Seasoning (1 teaspoon): A quick way to amp up the savory notes—think pepper, garlic, and a touch of smokiness.
- Baby Potatoes (1 1/2 pounds, quartered): Petite, creamy, and they soak up all the good flavors—no need to peel!
- Yellow Onion (1 small, diced): Adds natural sweetness and aroma to balance out the richness.
- Red Bell Pepper (1, diced): For a pop of color and subtle sweetness that brightens the entire bake.
- Garlic (2 cloves, minced): Because any true comfort casserole needs a garlicky punch.
- Smoked Paprika (1/2 teaspoon): This will deepen the flavor and add that signature cowboy smokiness.
- Shredded Cheddar Cheese (1 cup): Melts into gooey, golden bliss and ties everything together.
- Bacon Crumbles (1/2 cup, cooked): Crispy, salty, and utterly irresistible—skip if you must but you’ll miss them.
- Sour Cream (1/4 cup, optional): Spoonfuls of creamy cool relief against all that savory heat.
- Green Onions or Parsley (2 tablespoons, chopped): Fresh greenery for garnish and a little crunch.
- Salt and Pepper (to taste): Simple pantry must-haves to bring all the flavors into balance.
How to Make Cowboy Steak and Potato Casserole
Step 1: Sear the Steak
Get things started by preheating your oven to 400°F (200°C). While the oven warms, place a large skillet over medium-high heat and add a tablespoon of olive oil. Toss your steak pieces with steak seasoning, then sear them on each side for 2–3 minutes. The goal is a golden-brown crust—not to cook them through. Once they’re browned and mouthwateringly aromatic, slide them off the heat and set them aside for later.
Step 2: Prep the Potatoes and Veggies
In a spacious bowl, collect your quartered baby potatoes, diced onion, red bell pepper, minced garlic, and smoked paprika. Add in a generous shake of salt and pepper, then drizzle with the remaining olive oil. Give everything a good toss so the veggies are evenly coated and ready to crisp up in the oven, soaking up all those flavors.
Step 3: Roast the Vegetables
Grab a 9×13-inch baking dish and lightly grease it. Spread the potato and vegetable mixture across the bottom, making sure the pieces are in a nice, even layer. Slide the dish into your hot oven and roast for 20–25 minutes. The potatoes should be nearly—though not fully—tender, and the whole kitchen will be brimming with that smoky, garlicky aroma.
Step 4: Add Steak and Cheese
Pull the baking dish from the oven. Gently stir in your just-seared steak pieces along with half the shredded cheddar cheese. Mix to disperse everything evenly, then slip the dish back into the oven for another 10–15 minutes. You’re looking for fork-tender potatoes and steak cooked just the way you like it.
Step 5: Finishing Touches
Time for the final flourish! Pull the casserole back out and sprinkle with the remaining cheddar and those irresistible bacon crumbles. Return it to the oven for another 3–5 minutes, just to melt the cheese into bubbling perfection. Rest the casserole for about five minutes before serving—it’s tough to wait, but trust me, it’s worth it!
How to Serve Cowboy Steak and Potato Casserole
Garnishes
For that classic steakhouse finish, crown your Cowboy Steak and Potato Casserole with a dollop of sour cream and a generous handful of chopped green onions or parsley. The coolness from the sour cream balances the heat beautifully, while those fresh greens make every serving pop with color and crunch. It’s simple but makes each bite feel extra special.
Side Dishes
This casserole is hearty enough to shine solo, but if you’re setting a bigger table, a crisp green salad with a zesty vinaigrette adds just the right amount of lightness. Or serve with roasted green beans or sweet corn on the cob—these classic sides pair effortlessly with the rich flavors of Cowboy Steak and Potato Casserole.
Creative Ways to Present
Feeling playful? Try scooping the casserole into individual mini skillets or ramekins for a rustic, crowd-pleasing presentation. For family-style fun, pile it high on a wooden serving board straight from the oven and let everyone dig in, cowboy style. You can even use it as a hearty filling for fluffy baked potatoes or crusty rolls for a fun party twist!
Make Ahead and Storage
Storing Leftovers
Cowboy Steak and Potato Casserole makes fantastic leftovers and stores well, tightly covered in the fridge, for up to three days. To keep the textures at their best, let the casserole cool slightly before refrigerating, and store the sour cream garnish separately if possible.
Freezing
If you want to make your future self very happy, portion any leftovers into airtight containers and freeze for up to two months. Allow the casserole to cool completely before freezing to keep everything fresh and flavorful. Thaw overnight in the refrigerator before reheating so it warms through evenly.
Reheating
To reheat, cover your portion lightly with foil and warm in a 350°F (175°C) oven until heated through—about 20 minutes for a larger serving. A splash of water or broth in the pan will help prevent the potatoes from drying out. In a hurry? The microwave works just fine for individual servings; add the sour cream and green onions right before digging in.
FAQs
Can I substitute a different cut of beef?
Absolutely! While sirloin or flank steak gives you the best mix of tenderness and rich flavor, you can use ribeye, strip steak, or even leftover grilled steak for your Cowboy Steak and Potato Casserole. Just be sure to cut your chosen cut into bite-sized pieces before searing.
What’s the best way to make this casserole spicier?
To bring some heat to your casserole, stir in diced jalapeños with your potatoes and veggies, or sprinkle a pinch of cayenne pepper over the steak before searing. This gives Cowboy Steak and Potato Casserole a bold bite without overpowering the other flavors.
How do I make it gluten-free?
Great news—this recipe is naturally gluten-free as long as your steak seasoning doesn’t contain any hidden gluten. Always check labels or make your own blend of salt, pepper, garlic powder, and paprika for peace of mind.
Is it possible to prep this casserole ahead of time?
Yes! You can roast the potatoes and sear the steak a day ahead, storing them in the refrigerator separately. When it’s go-time, simply combine all the components with cheese and bacon, then bake as directed. That way, homemade comfort is never more than half an hour away.
Can I add other veggies?
Definitely! Feel free to add mushrooms, zucchini, or even sweet potatoes for extra flavor and nutrition in your Cowboy Steak and Potato Casserole. Just be mindful to chop everything to a similar size so they roast evenly.
