- Butter (4 tablespoons): For that irresistible, silky garlic butter sauce that coats the steak bites perfectly.
- Garlic cloves (4, minced): Fresh garlic adds a fragrant punch that garlic powder can’t quite replace.
- Garlic powder (1 teaspoon): Enhances the garlic flavor while seasoning the steak bites evenly.
- Salt and pepper: The classic duo that brings out the natural flavor of the steak and vegetables.
- Potatoes (4 medium, russet or Yukon gold): Your choice of potato ensures creamy and fluffy mashed potatoes every time.
- Unsalted butter (½ cup for mashed potatoes): Adds richness and smoothness to the mash.
- Milk or heavy cream (½ cup): This creates the perfect texture—silky yet hearty—for your mashed potatoes.
- Green beans: Fresh green beans bring color, crunch, and that fresh garden vibe to the plate.
How to Make Garlic Butter Steak Bites with Mashed Potatoes and Green Beans Recipe
Step 1: Cook the Green Beans
Begin by bringing a large pot of salted water to a boil. Toss in your green beans and cook them just until they turn tender-crisp, typically about 5 to 7 minutes. This step ensures the beans maintain their vibrant green color and a satisfying snap. Once cooked, drain and set them aside to keep warm.
Step 2: Cook the Steak Bites
Season your steak bites generously with salt, pepper, and garlic powder for maximum flavor layering. Heat 2 tablespoons of butter in a large skillet over medium heat, then add your steak bites. Let them sear, undisturbed, for about 4 to 5 minutes per side until you get that gorgeous golden-brown crust and they reach your preferred doneness. Afterward, remove the steak bites and set them aside, catching all those delicious juices.
Step 3: Make the Garlic Butter Sauce
In the same skillet, melt the remaining butter and toss in the minced garlic, sautéing gently until it’s fragrant and golden but not burnt. To really elevate the dish, stir in any steak juices you collected — this transforms your garlic butter into a rich, savory sauce that clings beautifully to each bite of steak.
Step 4: Prepare the Mashed Potatoes
While your steak and green beans are cooking, peel and cube your potatoes. Boil them until tender, then drain thoroughly. Mash them up with the unsalted butter and milk or heavy cream until perfectly smooth and creamy. Season with salt and pepper to taste, making sure every spoonful feels like pure comfort.
Step 5: Assemble the Dish
Now comes the fun part! Arrange your steak bites on a serving plate and generously spoon that heavenly garlic butter sauce on top. Place a generous scoop of mashed potatoes and a serving of green beans on the side. If you like, add a sprinkle of freshly chopped parsley for a pop of color and freshness.

Garnishes
Simple garnishes take your Garlic Butter Steak Bites with Mashed Potatoes and Green Beans Recipe from delicious to dazzling. A sprinkle of fresh parsley or chives adds brightness and a lovely herbal note, while a grind of fresh black pepper enhances the steak’s rich flavor. You might also try a few lemon wedges on the side for a little citrus kick that cuts through the richness.
Side Dishes
This dish can shine as a complete meal, but a few complementary sides can elevate the experience. A crisp green side salad with a zesty vinaigrette adds refreshing contrast. Garlic bread pairs wonderfully, doubling down on that beloved garlic taste. And for a truly special dinner, a glass of peppery red wine intensifies the steak’s savory depth.
Creative Ways to Present
Presentation can be as simple or as elaborate as you like. Try stacking the steak bites atop the mashed potatoes and drizzle the garlic butter sauce over the entire plate for a rustic yet elegant look. Serve family-style on a large wooden board for gatherings, placing green beans in small ramekins to add height and structure. You might even garnish with edible flowers or microgreens to surprise and delight guests.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers — though unlikely! — be sure to cool the steak bites, mashed potatoes, and green beans completely before transferring them separately into airtight containers. Store them in the refrigerator for up to 3 days to keep each component fresh and flavorful.
Freezing
While this Garlic Butter Steak Bites with Mashed Potatoes and Green Beans Recipe is best enjoyed fresh, you can freeze leftover mashed potatoes and green beans without much trouble. Steak bites tend to be best fresh but can be frozen if necessary in a sealed container or heavy-duty freezer bag for up to 2 months. Thaw thoroughly before reheating to maintain quality.
Reheating
When it’s time to enjoy the leftovers, gently reheat the steak bites in a skillet over low heat to preserve their tenderness, preferably with a little extra garlic butter sauce to keep them moist. Reheat mashed potatoes and green beans separately, using the microwave or a stovetop pan to protect their textures and flavors.
FAQs
Can I use other cuts of steak for this recipe?
Absolutely! Flank or sirloin steak works beautifully thanks to their tenderness and flavor, but you can experiment with ribeye or tenderloin for richer or leaner options. Just slice against the grain to keep each bite tender.
What can I substitute for heavy cream in the mashed potatoes?
If you don’t have heavy cream on hand, whole milk or half-and-half can be used to achieve creamy mashed potatoes. For an extra twist, a dollop of sour cream or cream cheese can add lovely tang and richness.
Can I make this recipe dairy-free?
Yes! Swap the butter with a plant-based alternative or olive oil, and use coconut or almond milk in your mashed potatoes. The garlic butter sauce can be recreated with olive oil and plenty of fresh garlic to keep that savory flavor.
How do I make sure my steak bites stay tender?
Choosing the right cut and slicing against the grain is key. Also, avoid overcrowding the skillet so the steak bites sear rather than steam. Cooking to medium-rare or medium keeps them juicy without drying them out.
Can I add other vegetables to this dish?
Definitely! Roasted carrots, sautéed mushrooms, or a simple salad can complement the Garlic Butter Steak Bites with Mashed Potatoes and Green Beans Recipe beautifully. Just keep timing in mind to ensure everything lands on the table warm and fresh.
