Okay, here’s the deal: this garlic butter steak and potatoes skillet is the best on the internet, full stop. The steak is perfectly cooked (if you’re a rare or medium rare steak lover, give it a try. I promise it’ll knock your socks off), and the potatoes are roasted to absolute perfection.

During the research phase of recipe development for this one, we found that A LOT of the steak and potatoes recipes on Google right now result in delicious, perfectly cooked steak but very, very underdone potatoes. Because of that, this recipe calls for roasting your potatoes (separately from the steak) for 30 minutes before adding them to skillet with the steak. While this results in a NOT one-skillet meal, it’s just as easy with much better results.

  • Flank steak – we went with flank steak here because it’s incredibly versatile and stays nice and tender even if it’s not cooked to rare (or medium rare), unlike other types of steak.
  • Fresh herbs – fresh rosemary, fresh thyme, and fresh oregano are all included in this steak and potatoes recipe. You *can* use dried, but if you can get your hands on fresh, we highly recommend it.
  • Coconut aminos – a lot of garlic butter steak and potatoes skillets call for soy sauce in the buttery steak marinade, but we actually prefer the slight sweetness that the coconut aminos adds. If you’ve never purchased coconut aminos, you can either find it near the soy sauce or on the health food aisle at your local grocery store.

A full ingredient list with exact amounts can be found in the recipe card below.

Recipe Variations and Modifications

  • Change up the flavor – swap the fresh herbs in the steak marinade for any seasoning blend you love. A ranch blend (butter, garlic, and fresh or dried dill) would be delicious.

Recipe Tip

  • Sear your steak over HIGH heat – don’t mess around with medium (or even medium/high) heat for this recipe. If you want the steak to get caramelized with a nice crust on it, be sure to sear over high heat.
  • Double the steak – if your skillet is large enough, consider doubling the amount of steak in this recipe. I did this the first time I made the recipe and we ended up using the deliciously flavorful steak for the next several mornings steak and eggs-style.

How to Serve

Serve your steak and potatoes skillet as is for a delicious, satisfying meal, or, if you want to add a green veggie component, roasted broccoli, roasted green beans, or even a simple arugula salad would all be delicious picks.

How to Store and Reheat

Store any leftovers in an airtight container in the fridge for up to 3 days.

To reheat your steak and potatoes, either pop a serving in the microwave for 1-2 minutes or reheat on a skillet over medium heat for 8-10 minutes, until warmed through.

Frequently Asked Questions

Can I use stew meat?

While you can use stew meat here, we don’t recommend it. Stew meat gets nice and tender after cooking it for a long time (usually either in the slow cooker or a pot on the stove), but it isn’t ideal for short cooking stints.

What does covering steak in butter do?

The butter in this recipe helps the steak to form a caramelized crust on the outside and adds a TON of flavor.

Why are my potatoes undercooked?

This was actually the exact problem we were aiming to solve with all of the current steak and potatoes skillets out there. Because this recipe calls for cooking the potatoes separately from the steak, you’ll be able to get them nice and soft before combining the two components together.

  1. This sounds amazing! Yum! This recipe may need to be just slightly edited. In the ingredient list it doesn’t mention about cutting the steak into bite sized pieces. It just says 1.5lb flank steak. In the instructions it then says toss steak bites in sauce… only in the notes section does it mention about cutting the steak. I can’t wait to make this though!

    1. Hi Lauren! Just updated the recipe! We are so excited for you to try it!

  2. How thick am I slicing the steak? It just says about slicing across the grain. Do I then cut the slices into pieces? Thanks, because I can’t wait to make this!

    1. Hi Kimberly! Great catch… Updating the recipe now! You will cut the steak into 1-inch pieces!

    2. 5 stars
      Finally made this- A Huge Hit! Super simple to make with lots of flavor. Very little mess to clean up- making it even more of a win
