Key Takeaways: Steak and Potatoes Recipe

  • One-pan dinner: The steak and potatoes cook in the same cast iron skillet, keeping both prep and cleanup simple.
  • Juicy steak bites: Sirloin is cut into bite-size pieces and quickly seared so the outside browns while the inside stays tender.
  • Golden seasoned potatoes: Baby gold potatoes cook in olive oil and butter with Italian seasoning, garlic powder, salt and pepper until fork tender.
  • Garlic butter finish: Fresh garlic and butter are added to the steak before everything is tossed back together for a rich, savory finish.

Why I Love This Recipe

There’s just something so good about steak and potatoes, especially when you can make the whole meal in one skillet. The potatoes get golden and crisp around the edges while the sirloin steak stays juicy, then everything gets tossed with garlic, butter and herbs.

When I have more time, I love making a perfect grilled steak or steak in the oven. This skillet version, though, is perfect for busy nights because it cooks together for a complete dinner in just 30 minutes.

  • Sirloin steak: This cut of meat is perfectly suited for being pan seared and will get nice and tender! Beef tenderloin, NY strip steak or flank steak also work well.
  • Potatoes: Yukon gold potatoes are a great choice with their buttery taste. Large potatoes will need to be quartered and baby potatoes halved. Red potatoes is any easy swap!
  • Garlic: Freshly minced garlic cloves are best to use in this dish.
  • Olive oil: I prefer olive oil when I am searing the steak over high heat.
  • Butter: I usually use unsalted butter, if I have garlic herb butter on hand it make this steak bites and potatoes recipe exceptional!
  • Seasonings: I like to use my homemade Italian seasoning for the potatoes and steak rub to marinate and tenderize the meat. Salt and pepper add taste.
  • Fresh herbs (optional): Fresh rosemary and thyme add more flavor.

How to Make Steak and Potatoes

Step 1: Start by seasoning the steak and letting it sit while you get the potatoes going. Even 10 to 15 minutes gives the seasoning a little time to work its way into the meat.

Step 2: Cook the potatoes first in a little olive oil and butter, then add the Italian seasoning, garlic powder, salt and pepper. Don’t rush this part since those crisp browned edges add so much flavor.

Step 3: Move the potatoes to a plate and turn up the heat before adding the steak. Spread the pieces out so they can actually sear instead of steam, then flip once the bottoms have developed a nice crust.

Step 4: Once the steak is almost done, add the remaining butter and fresh garlic and cook briefly until fragrant. Return the potatoes to the skillet, toss everything in the garlic butter, then remove from the heat so the steak doesn’t overcook.

Recipe Tips

  • Choose the right steak. Sirloin is tender, flavorful and usually more budget-friendly than many other cuts. I’d skip pre-cut stew meat since it generally needs a longer cook time to become tender.
  • Let the steak rest after seasoning. Season the steak before you start the potatoes and let it sit for 10 to 15 minutes. It gives the seasoning time to flavor the meat while you prep everything else.
  • Cut against the grain. Slice the steak against the grain before cutting it into bite-size pieces. This shortens the muscle fibers and gives you a more tender bite.
  • Give the potatoes time to brown. Stir them occasionally rather than constantly so they can develop crispy golden edges. If they’re browning before they’re tender, lower the heat, add a splash of water and cover for a few minutes to steam them.
  • Try them on the grill. For a summer version, use the same steak-and-potatoes combination to make steak and potato foil packs with almost no cleanup.

Serving Suggestions

The best part of this easy steak and potatoes dinner is that there is already a side. If you need a vegetable my sauteed green beans are great and no one ever turns down fresh dinner rolls!

Steak and Potatoes FAQs

Do I cook the potatoes or steak first?

Cook the potatoes first since they take much longer than the steak. Once they’re golden and fork tender, transfer them to a plate, increase the heat and quickly sear the steak. Add the potatoes back at the end so everything finishes together without overcooking the beef.

How do I get a good sear on the steak?

Make sure the skillet is nice and hot before adding the steak, then arrange the pieces in a single layer with a little space between them. Let the steak sit for about a minute before flipping so it has time to develop that browned crust. Avoid stirring it constantly.

What if my potatoes start burning before they’re done?

Turn the heat down and add a small splash of water to the skillet. Cover for a few minutes to let the potatoes steam until tender, then uncover and let any remaining water cook off. You’ll still get those golden edges without scorching the outside.

Should I marinate the steak first?

You don’t need to for this recipe. Seasoning the steak and letting it rest for 10 to 15 minutes gives it plenty of flavor. If you have extra time, you can use my easy steak marinade, but pat the steak very dry before cutting and searing it so the excess moisture doesn’t interfere with browning.

Equipment

  • cast iron skillet

Ingredients 

  • 2 teaspoons steak seasoning , or sub for salt and pepper
  • 1 pound sirloin steak
  • 1 Tablespoon olive oil
  • 3 Tablespoons butter
  • 1 pound baby gold potatoes diced, about 3 cups
  • 1 teaspoon Italian seasoning , plus more to taste
  • ½ teaspoon garlic powder
  • salt and pepper , to taste
  • 3 cloves garlic (3 teaspoons minced)

Optional: fresh herbs such as rosemary or thyme

Instructions

  • Prepare potatoes and steak. Rub 2 teaspoons steak rub (or salt and pepper) over the meat and let rest for 10-15 minutes while you cook the potatoes.
  • Cook potatoes. Heat cast iron skillet over medium heat. Add 1 Tablespoon olive oil and 1 Tablespoon butter. Once butter has melted, add 1 pound potatoes into the skillet and stir until coated.

Cook for 15-20 more minutes (or until fork tender), stirring occasionally to prevent burning. Set aside on a plate once cooked.

Place evenly on the pan and let sear for 1 minute and then flip with a fork or spatula to the other side. Cook an additional 1-2 minutes or until golden brown and no longer pink. Be careful to not over cook.
