Directions: How to Make Steak Bites with Mashed Potatoes
Prep the Mashed Potatoes
- Add peeled and cubed potatoes to a large pot. Cover with cold, salted water and bring to a boil over high heat.
- Reduce heat to medium and simmer for 15-20 minutes, or until potatoes are fork-tender.
- Drain well, then return potatoes to the pot. Add 1 tbsp butter, milk, sour cream, and 1/2 tsp salt. Mash until smooth and creamy, adding more milk if needed. Cover to keep warm.

Sear the Steak Bites
- Pat steak cubes dry with paper towels. Toss with salt, black pepper, and smoked paprika.
- Heat olive oil in a large skillet (preferably cast iron) over medium-high heat. When shimmering hot, add steak bites in a single layer (work in batches if needed).
- Sear for 2 minutes without stirring, then flip and cook another 1-2 minutes for medium-rare. Remove to a plate and tent with foil.
Make the Garlic Butter
- Reduce skillet heat to medium. Add remaining tbsp butter and minced garlic. Sauté for 30 seconds until fragrant, scraping up any browned bits.
- Return steak bites to the skillet and toss to coat in garlic butter for 1 minute.
Serve
- Spoon creamy mashed potatoes onto plates, top with juicy steak bites and any skillet juices. Garnish with chopped parsley. Enjoy!
