👨‍🍳 Step-by-Step Instructions

1. Prepare the Mashed Potatoes

Start with the mash, since it takes longer.

  • Place potatoes in a pot with cold, salted water (and garlic cloves, if using).
  • Bring to a boil and cook until fork-tender, about 15–20 minutes.
  • Drain well and return to the pot.
  • Add butter and milk/cream, then mash until smooth and creamy.
  • Season with salt and pepper to taste. Cover and keep warm.

🧈 Optional: Add a dollop of sour cream or a handful of grated cheese for extra richness.

2. Sear the Steak Bites

While the potatoes cook:

  • Pat steak cubes dry with paper towels (moisture prevents browning).
  • Season generously with salt and pepper.

Heat olive oil in a large skillet over medium-high heat. Once hot:

  • Add steak cubes in a single layer (work in batches if needed)
  • Sear for 2–3 minutes per side, until browned and cooked to your preferred doneness
  • Remove from pan and set aside

🥩 Avoid overcrowding the pan – this ensures you get that beautiful sear instead of steaming the meat.

3. Make the Garlic Butter Sauce

In the same skillet (don’t clean it — keep the browned bits!):

  • Lower heat to medium
  • Add butter, letting it melt and foam
  • Stir in minced garlic and red pepper flakes (if using)
  • Sauté for 30–60 seconds, until fragrant (do not burn the garlic)

Return the steak bites to the pan and toss to coat in the garlic butter.

Sprinkle with chopped parsley, and remove from heat.

4. Serve

Spoon a generous portion of creamy mashed potatoes onto a plate.
Top with sizzling garlic butter steak bites and drizzle extra sauce over the top.
Garnish with a bit more parsley or a crack of black pepper.

🍷 Pair with red wine or a crisp, cold beer for a bistro-style meal at home.

📌 Pro Tips for the Best Garlic Butter Steak Bites and Mash

Use the Right Cut of Beef

  • Sirloin: Leaner, still flavorful and budget-friendly
  • Ribeye: More marbled, richer flavor
  • Tenderloin: Premium choice, super tender

Dry the Meat Thoroughly

Moisture causes steaming. Dry steak = better browning and flavor.

Don’t Overcook the Garlic

Garlic burns quickly. Sauté just until fragrant, then toss in steak bites.

Upgrade the Mash

  • Add roasted garlic for a deeper flavor
  • Mix in cream cheese for extra creaminess
  • Use a potato ricer for ultra-smooth texture

🍽️ Variations and Add-Ons

Mushroom & Steak Bites

Sauté mushrooms in the garlic butter before adding steak back in.

Blue Cheese Crumbles

Sprinkle crumbled blue cheese over hot steak bites just before serving.

Steak & Mash Bowl

Serve with roasted veggies (like broccoli or green beans) for a complete meal bowl.

Chili-Garlic Steak Bites

Add 1 tsp of chili paste or sriracha to the butter for a spicy twist.

🥶 Storage and Reheating

  • Refrigerate leftovers in an airtight container for up to 3 days
  • Reheat in a skillet with a bit of butter over medium heat
  • Microwave gently in short bursts if in a pinch (mash heats faster than steak)

❄️ Mashed potatoes and steak bites can be frozen separately, though fresh is best for texture.

💬 Frequently Asked Questions

Can I use frozen steak?

Yes, but thaw completely and pat dry before cooking for best sear.

Can I make it dairy-free?

Use plant-based butter and milk alternatives. The flavor will vary, but the method remains the same.

What’s the best potato for mashed potatoes?

Yukon Gold gives a creamy, buttery finish. Russet makes fluffier mash.
