Step-by-Step Instructions

🔪 Prep the Ingredients

Before you start cooking, make sure all your ingredients are prepped:

  • Peel and cube the Yukon Gold potatoes.
  • Cut your steak into 1-inch cubes.
  • Slice the onion thinly.

🥔 Make the Mashed Potatoes

  1. Place the cubed potatoes in a large pot and cover with cold, salted water.
  2. Bring to a boil and cook for 15–20 minutes, until fork-tender.
  3. Drain and return the potatoes to the pot.
  4. Add heavy cream, butter, sour cream, salt, and black pepper.
  5. Mash until smooth and creamy. Cover and keep warm.

Pro Tip: Use a potato ricer for the creamiest mashed potatoes with zero lumps!

🥩 Cook the Steak and Onions

  1. Pat the steak cubes dry with paper towels to ensure a good sear.
  2. In a bowl, toss the steak with 1 tablespoon of olive oil, Worcestershire sauce, garlic powder, onion powder, smoked paprika, salt, and black pepper.
  3. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
  4. Add the steak cubes in a single layer and sear for 2–3 minutes per side until medium doneness (135°F/57°C). Remove and set aside.
  5. In the same skillet, add the butter and sliced onions.
  6. Sauté for 5–7 minutes until the onions are golden and caramelized.
  7. Return the steak bites to the skillet, tossing to coat them in the onions and flavorful juices.

Shortcut Tip: If you’re short on time, you can caramelize onions in advance and store them in the fridge for up to a week.

🍴 Serve It Like This

  1. Spread a generous layer of mashed potatoes on a large serving platter or individual plates.
  2. Top with the steak bites and caramelized onions.
  3. Spoon any leftover pan juices over the top.
  4. Garnish with fresh chopped chives.

Recipe Swaps and Variations

  • Protein: Try this with chicken breast cubes, pork tenderloin, or even shrimp for a twist.
  • Potatoes: Swap Yukon Gold for red potatoes or even sweet potatoes for a different flavor profile.
  • Seasonings: Add a pinch of cayenne pepper for some heat, or replace Worcestershire sauce with soy sauce for an umami bomb.
  • Dairy-Free: Substitute coconut cream for heavy cream and plant-based butter for traditional butter.

How to Store and Reheat Leftovers

If you have leftovers (lucky you!), here’s how to keep them delicious:

  • Storage: Place steak bites and mashed potatoes in separate airtight containers. Store in the fridge for up to 3 days.
  • Reheating: Gently reheat steak bites in a skillet over medium heat. Reheat mashed potatoes in the microwave or on the stovetop with a splash of milk or cream to bring back their creamy texture.
  • Freezing: Mashed potatoes freeze beautifully for up to 2 months. Steak bites can be frozen, but they’re best enjoyed fresh to maintain tenderness.

Food and Drink Pairings

  • Vegetables: Serve alongside green beans, asparagus, or a crisp Caesar salad.
  • Wine: A full-bodied red like Cabernet Sauvignon or Malbec complements the richness of the steak.
  • Beer: Try a dark stout or amber ale.
  • Cocktail: An Old Fashioned or Manhattan would be a stellar match!

FAQs About Steak Bites with Mashed Potatoes

Can I use a different cut of steak?

Absolutely! Sirloin and ribeye are preferred for their tenderness, but flank steak or NY strip also work well.

What if I don’t have Yukon Gold potatoes?

No problem. Russet potatoes are a fine substitute; just note that they yield a fluffier mash compared to the creamy texture of Yukon Golds.

How do I know when my steak bites are cooked perfectly?

Use a meat thermometer for accuracy. Aim for 135°F (57°C) for medium doneness.

Can I make this dish ahead of time?

You can prepare the mashed potatoes and caramelized onions ahead of time. Cook the steak bites just before serving for best results.
