Ingredients
  

  • 1 tbsp olive oil divided: 1/2 tbsp for potatoes, 1/2 tbsp for steak
  • 2 tbsp butter divided: 1 tbsp for potatoes, 1 tbsp for steak
  • 1 lb baby red and yellow potatoes cut into 1/2-inch cubes, as evenly as possible
  • 3 large garlic cloves minced
  • 1 tsp fresh parsley chopped, plus extra for garnish
  • 1 tsp fresh thyme chopped, plus extra for garnish
  • 1 tsp fresh rosemary chopped
  • 0.25 tsp red pepper flakes use up to 1/2 tsp to taste, omit when serving to children
  • 1 lb sirloin steak cut into 1-inch cubes, up to 1 1/4 lb. Pull from fridge 15 min before cooking. Ribeye or New York strip also work.
  • salt and pepper to taste

Equipment

  • Large cast-iron skillet
  • Cutting board
  • Sharp knife
  • Tongs
  • Instant-read thermometer

Method
 

  1. Heat a large cast iron skillet over medium heat. Add 1 tbsp butter and 1/2 tbsp olive oil. Once hot, add cubed potatoes, garlic, fresh herbs, and red pepper flakes. Cook 5 to 6 minutes until potatoes are just tender when pierced with a fork. Season with salt and pepper.
  2. Transfer potatoes to a plate and set aside. Check the skillet for burnt garlic or herb bits and discard them. Burnt garlic left in the pan will make the steak bitter.
  3. Turn heat to high. Let the skillet heat until it just begins to smoke lightly, about 1 to 2 minutes. Add remaining 1/2 tbsp olive oil and 1 tbsp butter. Add steak bites in a single layer without crowding. Sear undisturbed for 1 full minute to develop a proper brown crust.
  4. Continue cooking, turning the steak bites, until browned on all sides and cooked to preferred doneness, about 4 to 6 minutes total. For medium, internal temperature should reach 145F. Sear in batches if needed. Season with salt and pepper.
  5. Return potatoes to the skillet and cook together for 1 more minute until heated through. Serve immediately garnished with fresh chopped parsley and thyme.

Notes

Pull steak from the fridge 15 minutes before cooking for a more even sear. Prep all ingredients before cooking as this recipe moves fast. Always discard burnt garlic from the skillet before searing the steak. Never crowd the steak in the pan or it will steam instead of sear. For best results use sirloin, ribeye, or New York strip. Omit red pepper flakes when serving to children. Leftovers keep in the fridge up to 3 days. Reheat in a skillet with butter on medium heat or in an air fryer at 375F for 3 to 4 minutes.
