Equipment

  • 1 large skillet
  • 1 pot for boiling potatoes
  • 1 colander
  • 1 potato masher or ricer
  • 1 set measuring cups and spoons
  • 1 knife and cutting board

Ingredients
  

  • 1 lb sirloin steak, cut into 1-inch cubes
  • 2 tablespoons olive oil
  • 4 tablespoons unsalted butter For steak bites
  • 4 cloves garlic, minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 tablespoon fresh parsley, chopped Optional, for garnish
  • 2 lbs russet potatoes, peeled and cut into chunks
  • ½ cup milk
  • 4 tablespoons unsalted butter For mashed potatoes
  • Salt and pepper to taste For mashed potatoes

Instructions
 

  • Begin by boiling the potatoes. In a large pot, add the potato chunks and cover them with water. Bring to a boil over medium-high heat. Cook for about 15-20 minutes, or until fork-tender.
  • While the potatoes are boiling, heat a large skillet over medium-high heat. Add the olive oil to the skillet.
  • Season the steak cubes with salt and black pepper. Once the oil is hot, add the steak bites to the skillet, making sure not to overcrowd the pan. Sear the steak for about 2-3 minutes on each side, or until browned and cooked to your preferred level of doneness. Work in batches if necessary.
  • Reduce the heat to low and add the butter and minced garlic to the skillet with the steak. Stir to combine and let the garlic cook for about 1-2 minutes until fragrant.
  • Once the potatoes are finished cooking, drain them in a colander. Return the drained potatoes to the pot. Add in the milk, unsalted butter, salt, and pepper. Mash until smooth and creamy.
  • Serve the garlic butter steak bites hot, garnished with chopped fresh parsley if desired, alongside a generous scoop of creamy mashed potatoes.

Notes

For a bit of heat, consider adding crushed red pepper flakes to the garlic butter sauce.
You can substitute the russet potatoes with Yukon gold potatoes for a creamier texture in your mashed potatoes.
This dish pairs well with a side of steamed vegetables or a fresh salad.
