How to Make Garlic Butter Steak Bites with Mashed Potatoes and Green Beans Recipe
Step 1: Make the Mashed Potatoes
Start by bringing a large pot of salted water to a rolling boil. Toss in the peeled and cubed Yukon Gold potatoes and cook for 15 to 18 minutes until they yield easily to a fork. Drain well and return them to the pot. Add warm whole milk, sour cream, butter, and a pinch of salt and pepper. Mash everything together until you achieve a luscious, smooth consistency. Keep them covered to stay warm while you prepare the rest of the dish.
Step 2: Cook the Green Beans
While the potatoes are simmering, heat olive oil or butter in a skillet over medium heat. Add the trimmed green beans and sauté for about 5 to 6 minutes, allowing them to soften but remain crisp. Toss in the minced garlic, season generously with salt and pepper, and continue to cook for an additional 1 to 2 minutes. The garlic will release its aroma, gently infusing the beans without overpowering their natural freshness. Once they reach your preferred tenderness, set them aside.
Step 3: Prepare the Garlic Butter Steak Bites
Pat the steak cubes dry with paper towels—that’s the secret to getting a perfect sear. Season generously with salt and black pepper. Heat olive oil in a large skillet over medium-high heat and arrange the steak pieces in a single layer; sear for 1 to 2 minutes per side until each bite develops a beautiful golden crust. If your pan isn’t big enough, cook in batches to avoid overcrowding. Reduce the heat to medium, add butter and minced garlic, and toss the steak bites gently for 1 to 2 minutes so they soak up all that buttery, garlicky goodness. Finish with a sprinkle of fresh parsley for a pop of color and freshness.
How to Serve Garlic Butter Steak Bites with Mashed Potatoes and Green Beans Recipe

Garnishes
A sprinkle of freshly chopped parsley or a few extra garlic cloves crisped in butter can elevate the dish’s presentation and flavor. Fresh cracked black pepper on top adds an appealing spiciness that complements the richness of the steak bites perfectly.
Side Dishes
This meal is already a hearty, complete plate, but you can always add a crusty piece of garlic bread or a simple mixed green salad with vinaigrette to add freshness and crunch if you’re feeding a larger crowd or want an extra vegetable variety.
Creative Ways to Present
Serve the steak bites directly over a mound of mashed potatoes with green beans artistically arranged on the side for a classic look. Or, try plating the mashed potatoes first, then neatly stacking the green beans atop, and crowning it all with sizzling steak bites for an elegant dinner presentation guaranteed to impress guests.
Make Ahead and Storage
Storing Leftovers
Leftover Garlic Butter Steak Bites with Mashed Potatoes and Green Beans Recipe keeps beautifully in an airtight container in the fridge for up to 3 days. Keep the components separate to maintain optimal texture—especially the green beans to avoid sogginess.
Freezing
While mashed potatoes freeze well, steak bites and green beans sometimes lose their fresh texture after freezing. If freezing is necessary, store the mashed potatoes alone in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating gently.
Reheating
For best results, reheat mashed potatoes in the microwave or on the stovetop with a splash of milk to restore creaminess. Warm the steak bites and green beans separately in a skillet over low heat until heated through, preserving their flavors and textures.
FAQs
Can I use a different cut of steak for the garlic butter steak bites?
Absolutely! While sirloin and ribeye are great choices for their balance of tenderness and flavor, you can also use filet mignon, strip steak, or even flank steak. Just be mindful of cooking times as leaner cuts might cook faster and can dry out.
How can I make the mashed potatoes extra creamy?
Using Yukon Gold potatoes is already a great start, but adding warm milk and sour cream as described takes the creaminess up a notch. For an even richer mash, you might add a bit of cream cheese or a splash of heavy cream.
Is it possible to prepare this dish for a gluten-free diet?
Yes! This entire Garlic Butter Steak Bites with Mashed Potatoes and Green Beans Recipe is naturally gluten-free, just ensure any additional ingredients like Worcestershire sauce or seasoning blends you use are gluten-free as well.
How do I prevent the steak bites from overcooking?
To keep the steak juicy, don’t overcrowd the pan when searing, and cook in batches if needed. Sear each side quickly over high heat, then reduce the heat for the garlic butter step so the steak can absorb flavor without drying out.
Can I swap green beans for another vegetable?
Definitely. Asparagus, broccoli, or sautéed spinach make excellent alternatives that complement the steak and potatoes well while adding their own texture and green vibrance to the meal.
