Equipment
- 9×13 baking dish
- Foil
For the Steak & Veggies
- 2–3 medium russet potatoes
- 2 pounds sirloin or strip steak, cut into 2-inch cubes
- ½ pound fresh green beans, trimmed and cut into pieces (broccoli can be substituted)
- 1 sweet onion, sliced or diced
- 8 ounces button mushrooms, quartered
For the Herby Olive Oil
- ¼ cup olive oil (or more as needed) — melted butter works too
- 2 teaspoons garlic, minced
- 1 teaspoon salt
- 1 teaspoon black pepper
- 1 teaspoon onion powder
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- ½ teaspoon red pepper flakes (optional, for a little heat)
How To Make It
This hearty one-pan meal is a weeknight dream! Juicy steak bites, golden potatoes, fresh green beans, onions, and mushrooms are tossed in a garlicky herb olive oil and roasted together until perfectly tender and flavorful. Easy prep, minimal cleanup, and totally satisfying!
Preheat oven to 425°F.
Soften the potatoes: Clean and poke holes in the potatoes with a fork. Microwave for 3–6 minutes to soften slightly (time will vary based on size—larger potatoes need closer to 5–6 minutes).
Dice the potatoes into bite-sized cubes. Smaller pieces will help ensure they cook evenly with the steak.
Combine everything: In a large bowl, toss the steak, potatoes, green beans, mushrooms, and onions with the herbs and olive oil (or melted butter), until everything is well coated.
Transfer to a baking dish: Spread the mixture in a 9×13-inch casserole dish. Cover tightly with foil.
Bake for 25–40 minutes, or until steak reaches your preferred doneness and potatoes are tender.
- For medium steak, start checking around the 25-minute mark.
- For rare, reduce the time slightly. For well-done, bake a bit longer.
Serve hot, garnished with fresh parsley or a sprinkle of Parmesan if desired.
I love this recipe because it’s made in one dish, it’s already a full meal with no need to prepare additional sides and it’s an economical way for the whole family to enjoy steak. Plus it’s so easy! This will be a new family favorite!

Tips
- Par-cook the potatoes for even roasting. Microwaving the potatoes for a few minutes before baking softens them just enough to match the cook time of the steak. This ensures everything finishes at the same time without overcooking the beef.
- Cut everything into similar-sized pieces. Aim for uniform pieces of steak and veggies so they cook evenly. Dice the potatoes on the smaller side (especially if you like your steak more on the rare side).
- Use a high-quality cut of beef. Sirloin or strip steak works beautifully for this recipe. They’re tender, flavorful, and roast well without drying out.
- Don’t overcrowd the pan. If everything is too tightly packed, the veggies will steam instead of roast. If needed, divide the mixture between two pans for better caramelization.
- Let it rest before serving. Once the steak is done, give it 5 minutes to rest before serving. This helps the juices redistribute for maximum flavor and tenderness.
- Swap or add veggies based on what you have. This recipe is super flexible—zucchini, bell peppers, or cherry tomatoes are all great additions or swaps depending on what’s in your fridge. Also, melted butter can be used instead of olive oil.
- Leftovers: This dish reheats well and makes great leftovers for lunch. Store in airtight containers in the fridge for up to 3 days. I like to add a small pat of butter on top of the steak before reheating individual servings to add moisture.
