How to Make Garlic Butter Steak Bites with Creamy Mashed Potatoes Recipe
Step 1: Prepare the Mashed Potatoes
Start by peeling and cutting your potatoes into even chunks to ensure they cook uniformly. Boil them in salted water until fork-tender, about 15 to 20 minutes. Once perfectly soft, drain and return the potatoes to the pot, add butter, heavy cream, and if you like, minced garlic for that subtle garlic flavor. Mash everything together until smooth and creamy, seasoning with salt and freshly ground pepper to bring out the potato’s natural sweetness and richness. Keep warm while you prepare your steak bites.
Step 2: Cook the Garlic Butter Steak Bites with Creamy Mashed Potatoes Recipe
Heat olive oil over medium-high heat in a large skillet. Season your sirloin steak cubes generously with salt, pepper, dried thyme, and rosemary to layer in those wonderful herb notes. Add the steak cubes to the hot skillet and sear for about 3 to 4 minutes per side. The goal is to get a beautiful brown crust while keeping the inside tender and juicy. Remove the steak bites and set them aside briefly.
Step 3: Make the Garlic Butter Sauce and Finish
In the same skillet, melt your butter over medium heat and toss in the minced garlic, letting it cook just until fragrant—this step is where the magic happens, infusing the butter with savory garlic notes. Return the steak bites to the skillet and toss them thoroughly in this luscious garlic butter sauce to coat each piece evenly. This step ensures every bite is bursting with flavor.
Step 4: Plate and Serve
Spoon generous portions of your creamy mashed potatoes onto plates and crown them with the garlicky steak bites. Toss a sprinkle of fresh chopped parsley over the top for that inviting pop of color and freshness. Serve immediately to enjoy the best textures and flavors.
How to Serve Garlic Butter Steak Bites with Creamy Mashed Potatoes Recipe

Garnishes
Fresh parsley adds more than just color—it brings a refreshing herbaceous note that lightens the richness of the steak and potatoes. For an extra touch, a sprinkle of flaky sea salt or cracked black pepper right before serving can elevate the dish’s flavors beautifully.
Side Dishes
This Garlic Butter Steak Bites with Creamy Mashed Potatoes Recipe shines on its own, but if you want to round out your meal, consider serving with roasted vegetables like asparagus or Brussels sprouts. A crisp green salad dressed with a tangy vinaigrette also pairs wonderfully, balancing the rich steak and creamy potatoes with bright, fresh flavors.
Creative Ways to Present
For a cozy family dinner, pile the steak bites atop fluffy mashed potatoes family-style on a large platter, letting everyone help themselves. For something a little more elegant, arrange the potatoes as a base on individual plates with steak bites fanned out on top, garnished with parsley and a drizzle of the garlic butter sauce for a restaurant-worthy presentation.
Make Ahead and Storage
Storing Leftovers
Place leftover steak bites and mashed potatoes in airtight containers and refrigerate. Consume within 3 to 4 days for the best flavor and texture. Keep the steak separate from the potatoes if possible to maintain their individual textures.
Freezing
The creamy mashed potatoes freeze well; spoon them into freezer-safe containers for up to 2 months. Steak bites can be frozen too, but their texture may change slightly after thawing. For best results, freeze them separately and thaw in the fridge overnight before reheating.
Reheating
Reheat mashed potatoes gently on the stovetop with a splash of milk or cream to restore their creamy texture. Warm the steak bites quickly in a hot skillet to avoid overcooking. Cover the steak bites with foil in an oven set to 300°F if you prefer an even reheat without drying them out.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! While sirloin works great for tender, flavorful bites, you can also use ribeye or filet mignon for a richer or more tender experience. Just make sure to cut the steak into uniform bite-sized pieces for even cooking.
Is it necessary to use heavy cream in the mashed potatoes?
Heavy cream gives the mashed potatoes their signature creamy texture and richness, but if you prefer a lighter version, you can substitute with milk or half-and-half. Just keep in mind the texture may be less velvety.
Can I prepare any parts of this recipe ahead of time?
Yes! Mashed potatoes can be made a few hours in advance and kept warm on low heat or reheated gently before serving. Steak bites are best cooked fresh but can be prepped and seasoned beforehand to save time.
How do I know when the steak bites are cooked perfectly?
Cooking steak bites for about 3-4 minutes per side on medium-high heat will give you a nice sear and a juicy interior. Adjust the time depending on your preferred doneness, but keep an eye out for a golden-brown crust.
Can I add extra flavors to the garlic butter sauce?
Definitely! Try stirring in a splash of white wine, a squeeze of lemon juice, or some chopped fresh herbs like thyme or rosemary to add more complexity. Just be careful not to overpower the garlic butter base.
