Step-by-Step Instructions
Step 1: Prepare the Mashed Potatoes
1.1. Boil the potatoes:
Start by placing your peeled and cubed potatoes in a large pot. Cover with cold water to ensure even cooking and season the water with a generous pinch of salt. Bring to a boil over medium-high heat, then reduce the heat and simmer for about 12–15 minutes, or until the potatoes are fork-tender.
1.2. Drain and mash:
Drain the potatoes and return them to the pot. Add warm milk and butter. Using a potato masher, mash until smooth and creamy. Alternatively, for ultra-smooth mashed potatoes, use a hand mixer or ricer.
1.3. Season and keep warm:
Season with salt and pepper to taste. Cover and keep warm over low heat or in a warm oven while you prepare the steak bites.
Step 2: Cook the Garlic Butter Steak Bites
2.1. Prepare the steak:
Pat your steak cubes dry using paper towels. This helps achieve a beautiful sear. Season generously with salt and pepper.
2.2. Sear the steak:
Heat vegetable oil in a large skillet over medium-high heat. Once the oil is shimmering, add the steak pieces in batches to avoid overcrowding the pan. Sear each batch for about 2–3 minutes per side, until they’re browned and cooked to your preferred doneness. Remove steak bites from the pan and set aside on a plate.
2.3. Make the garlic butter sauce:
Lower the heat to medium. In the same skillet, add the butter. Once melted, stir in the minced garlic, thyme, and rosemary. Cook for 1–2 minutes, just until the garlic becomes fragrant and lightly golden. Be careful not to burn it.
2.4. Coat the steak bites:
Return the steak bites to the pan, toss them to coat in the butter sauce, and let everything warm through for another minute or so. Taste and adjust seasoning with more salt or pepper if needed.
Step 3: Plate and Serve
Spoon a generous serving of mashed potatoes onto each plate. Top with a hearty portion of steak bites and drizzle over any remaining garlic butter sauce from the skillet. Optionally, garnish with chopped parsley or chives for color and a hint of freshness.
Tips for Perfect Garlic Butter Steak Bites and Mash
1. Use a hot pan:
Ensure your skillet is very hot before adding the steak bites. This gives the meat a delicious crust and seals in the juices.
2. Don’t overcrowd the pan:
Cook in batches to allow proper browning. If the pan is crowded, the steak will steam instead of sear.
3. Choose the right cut:
Sirloin works great for tenderness and flavor. Ribeye or tenderloin are also excellent (and more luxurious) alternatives.
4. Don’t skip the drying step:
Moisture is the enemy of a good sear. Always dry steak thoroughly before cooking.
5. Make it creamier:
For ultra-luxurious mashed potatoes, replace some of the milk with cream or add cream cheese.
6. Add flavor depth:
A splash of Worcestershire sauce or soy sauce in the garlic butter can enhance umami flavor.
7. Try garlic confit:
If you have time, use slow-cooked garlic confit for a mellow, sweet garlic flavor.
Optional Add-Ons & Variations
-
Add veggies: Sautéed green beans, peas, or roasted carrots make excellent side dishes.
-
Steak & gravy: Add a splash of beef broth and thicken the butter sauce into a gravy.
-
Cheesy mash: Stir in shredded cheddar, gouda, or parmesan to the mashed potatoes.
-
Spice it up: Add a pinch of red pepper flakes or drizzle with hot sauce.
-
Low-carb swap: Serve steak bites with mashed cauliflower instead of potatoes.
Make Ahead & Storage
Make Ahead:
-
You can make the mashed potatoes a few hours in advance. Keep warm in a slow cooker on the “warm” setting.
-
Steak bites can be prepped by cutting and seasoning in advance, but sear them fresh for the best texture.
Storage:
-
Store leftovers in an airtight container in the fridge for up to 3 days.
-
Reheat mashed potatoes with a splash of milk and warm the steak gently to avoid overcooking.
