KEY INGREDIENTS IN GARLIC BUTTER STEAK BITES AND MASH
Before we dive into the cooking process, let’s take a moment to appreciate each ingredient that makes this recipe shine. From succulent steak cubes to pillowy mashed potatoes, every component plays a vital role in crafting a meal that’s bursting with flavor and texture.
- Steak
Whether you choose ribeye, sirloin, or another cut, the steak is the star of the show. Its natural marbling ensures tenderness and juiciness, while a quick sear locks in all those savory juices.
- Olive oil
This healthy fat helps achieve the perfect sear on your steak bites. It raises the smoke point and allows the meat to develop a beautiful brown crust.
- Salt and pepper
Simple seasonings that are absolutely essential. A generous sprinkle enhances the natural flavors of both the steak and the mashed potatoes.
- Unsalted butter
Used in two stages—first for the garlic herb sauce, then for the mashed potatoes. Butter brings a rich, creamy mouthfeel and carries the flavors of garlic and herbs beautifully.
- Garlic
Minced fresh for maximum aroma and taste, garlic infuses the butter with its warm, slightly pungent character.
- Thyme
Fresh or dried, thyme adds a subtle earthiness and pairs wonderfully with beef, brightening the overall profile of the sauce.
- Rosemary
This aromatic herb lends a piney, woodsy note that complements the richness of the steak and butter.
- Crushed red pepper flakes
Optional but highly recommended for those who enjoy a gentle kick of heat to balance the buttery richness.
- Potatoes
Yukon Gold or Russet both work beautifully. Peeled and chopped, they boil until tender and then transform into a silky mash.
- Heavy cream or milk
Added to the potatoes for creamy smoothness. Heavy cream yields extra richness, while milk gives a lighter finish.
- Sour cream
Optional for an extra tangy creaminess in your mashed potatoes, adding brightness that cuts through the butter.
HOW TO MAKE GARLIC BUTTER STEAK BITES AND MASH
Ready to bring all these delicious ingredients together? Follow these steps for a dish that’s always a hit:
1. Prepare the steak by cutting it into bite-sized cubes. Make sure each piece is roughly the same size for even cooking. Season generously with salt and pepper on all sides to enhance the meat’s natural flavors.
2. Heat the skillet by pouring in 2 tablespoons of olive oil and placing it over medium-high heat. Wait until the oil is shimmering hot—this ensures a quick, flavorful sear.
3. Sear the steak bites by arranging them in a single layer in the hot skillet. Let them cook undisturbed for 3–4 minutes per side, or until each cube is beautifully browned and reaches your preferred doneness. Work in batches if needed to avoid crowding and steaming the meat. Transfer cooked bites to a plate and set aside.
4. Lower the heat to medium and add 2 tablespoons of butter to the same skillet. Once melted, stir in the minced garlic, thyme, rosemary, and crushed red pepper flakes. Sauté for 1–2 minutes until the garlic softens and the herbs release their fragrant oils.
5. Return the steak bites to the skillet, gently tossing them in the garlic herb butter so each piece is coated. Let them cook together for another 1–2 minutes, allowing the flavors to meld. Then, remove the skillet from heat.
6. Boil the potatoes by placing the chopped spuds in a large pot and covering with water. Add a pinch of salt and bring to a rolling boil. Cook for 15–20 minutes or until the potatoes are fork-tender and easily pierced.
7. Drain and mash by returning the potatoes to the pot. Add 3 tablespoons of butter, the heavy cream (or milk), and sour cream if using. Use a potato masher or hand mixer to work the ingredients until the potatoes are smooth, creamy, and free of lumps. Season with additional salt and pepper to taste.
8. Assemble the dish by spooning a generous bed of mashed potatoes onto each plate. Top with the garlic butter steak bites, making sure to drizzle any remaining butter sauce over the top for maximum flavor.
SERVING SUGGESTIONS FOR GARLIC BUTTER STEAK BITES AND MASH
Once your Garlic Butter Steak Bites and Mash are plated, you’ve already won the dinner game—but why stop there? Elevate the experience with these fun and tasty serving ideas that will make every bite even more memorable:
- Add a side of steamed vegetables such as broccoli or green beans for a pop of color and a boost of freshness. Lightly toss them in olive oil, salt, and pepper so they complement rather than compete with your star entrée.
- Serve alongside a crisp mixed greens salad tossed in a tangy vinaigrette. The acidity will cut through the richness of the butter sauce and mashed potatoes, keeping your palate refreshed.
- Pair with a glass of full-bodied red wine—think Cabernet Sauvignon or Malbec—to accentuate the savory notes of the steak and herbs. The tannins in the wine balance beautifully with the creamy components of the dish.
- Garnish with a sprinkle of fresh chopped parsley or chives for a vibrant green flourish and a hint of herbal brightness. This small touch adds visual appeal and a fresh flavor lift to each mouthful.
HOW TO STORE GARLIC BUTTER STEAK BITES AND MASH
Have leftovers? No problem. With the right storage methods, you can enjoy these garlicky steak bites and creamy mash another day without sacrificing flavor or texture. Here’s how to keep everything at its best:
- Store in airtight containers by portioning steak bites and mashed potatoes into separate containers. This prevents the potatoes from absorbing too much meat juices and keeps both components at their ideal consistency. Refrigerate for up to 3–4 days.
- Freeze for longer by using freezer-safe bags or containers. Lay your steak bites flat in a single layer and place mashed potatoes on top or in a separate bag. Label with the date and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheat gently by warming your steak bites in a skillet over medium heat with a splash of water or broth to recreate that silky butter sauce. For mashed potatoes, microwave in short bursts, stirring between each interval, or heat on the stovetop with a pat of butter and a drizzle of cream to restore creaminess.
- Avoid sogginess by reheating components separately whenever possible. This keeps the steak bites’ sear intact and the mashed potatoes fluffy rather than gummy.
