Although you can easily cook sirloin steak in the oven by itself (or chop it into steak bites) and serve roasted potatoes on the side, this recipe for steak and potatoes in the oven cooks up everything one pan. Plus, you’ll love the mouthwatering caramelized onion butter!
Ingredients & Substitutions
Here I explain the best ingredients for potatoes and steak, what each one does in the recipe, and substitution options. For measurements, see the recipe card.
Top Sirloin Steaks – If possible, choose steaks that are 1.5 inch thick, as they are less likely to overcook. Although you can use other cuts of meat (such as New York strip steak, T-bone, ribeye steak, porterhouse, chuck eye steak, sliced tenderloin, or flank steak), their searing times will differ and you’ll want to use a probe meat thermometer to ensure doneness. Yellow Onions – I chose these for their classic flavor when caramelized, but you can use white onions, sweet onions, or Vidalia onions if you prefer. Worcestershire Sauce – For enhancing the meaty flavor in the steak. Soy sauce or coconut aminos can work as substitutes. Olive Oil – For creating a golden crust on the steak. Feel free to substitute your favorite neutral cooking oil, such as avocado oil. Dry Red Wine – Try a merlot, pinot noir, or cabernet sauvignon. Unsalted Butter – I prefer grass-fed butter for its excellent flavor, but use your favorite unsalted variety. Garlic – I recommend fresh garlic cloves for this steak and potato recipe, but minced garlic from a jar will also work. Yukon Gold Baby Potatoes – Cut them into quarters. You can also use conventional Yukon Gold potatoes or Russet potatoes, but they will need to be cut into smaller pieces. Any other potatoes you like will also work. Fresh Thyme – Adds depth and aromatic flavor to the steak and potato skillet. Other fresh herbs, like oregano or rosemary, would work well, too. Sea Salt & Black Pepper

Time Chart For Steak And Potatoes
Steak and potatoes cooked this way will take longer in the oven than sirloin steaks cooked alone, since the pan is more crowded, but the upside is that it’s a one-pan meal. It’s best use a meat thermometer or even better, a probe thermometer, to check when your steak is done. To give you an idea, a perfect medium-rare steak like the pictures above was seared for 2 minutes per side on the stovetop followed by 8-10 minutes in the oven. For 1.5-inch-thick steaks and an oven temperature of 375 degrees F, here is a temperature and time chart to get the doneness you want: Note: The times and temperatures above are what you want when removing steaks from the oven. The temperature will rise an additional 5 degrees as they rest. Once the steak is done, remove it and continue baking the potatoes for about 10 more minutes, until fork tender.
Storage Instructions
Store: Keep any leftover steak and potato in an airtight container in the refrigerator for up to 3 days. Meal prep: Caramelize onions ahead of time, prepare the caramelized onion butter, and store separately until the rest of the recipe is ready to cook. You can also dice the potatoes ahead of time and store submerged in water in the fridge (drain and pat dry before cooking). Reheat: Warm up leftovers in an oven at low heat, or briefly on the stovetop. The microwave is fine for the potatoes, but is likely to overcook and dry out the steak. Freeze: You can freeze roasted steak and potatoes for up to 3 months, but the texture of the potatoes may change.
What To Serve With Steak And Potatoes
This dish is a filling meal all on its own, but I always like to include veggies! Try these healthy sides:
Easy Veggies – Make oven roasted brussels sprouts, simple roasted garlic green beans, or buttery sauteeed mushrooms to pair with this hearty dish. Simple Salads – Try this meal with 7 layer salad if you want to prep ahead, quick creamy cucumber salad, or a more interesting spinach bacon salad. Steakhouse Sides – This dish pairs perfectly with classic creamed spinach, easy Instant Pot baked potatoes (make them in your pressure cooker while you have the steak and potatoes in the oven), mashed potatoes (or mashed cauliflower), or cheesy yellow squash casserole.
