When I first tried this recipe it felt like an instant classic. My kids started asking for it after chilly soccer practice nights and it soon became my ace-in-the-hole when hosting friends for casual dinners.
Ingredients
- Beef steak: Pick sirloin or ribeye for deep flavor and tender bites. Look for good marbling which means more juiciness.
- Olive oil: Creates an ideal crust on the beef. Choose extra virgin for best results.
- Unsalted butter: Adds rich flavor without extra salt. Use high-quality butter for the silkiest taste.
- Garlic: Freshly minced garlic delivers the best aroma. Avoid pre-chopped varieties for maximum punch.
- Salt: Brings all the flavors together. Use kosher or flaky salt for best control.
- Black pepper: Adds a mild heat and earthiness. Freshly cracked will make a difference.
- Red pepper flakes: Optional if you like a subtle kick. Use a pinch for gentle heat.
- Worcestershire sauce: Brings savory depth and a little tang. Small amounts go far.
- Fresh parsley: Brightens the dish and makes it look beautiful. Flat-leaf parsley is best.
- Yukon Gold or Russet potatoes: These mash easily and have a creamy texture. Choose potatoes that feel heavy and firm.
- Whole milk or heavy cream: Gives mashed potatoes that luscious consistency. The richer the cream the smoother your mash.
- Garlic powder: Optional but really boosts the flavor of the potatoes.
- Fresh parsley for garnish: Adds freshness and restaurant-worthy finish.
Step-by-Step Instructions
- Prep the Beef:
- Let steak rest at room temperature for about twenty minutes. This step ensures even cooking and a juicy center. After the rest pat the steak dry with paper towels so it browns not steams. Trim any excess fat and cut the steak into even bite-sized cubes for uniform cooking. Season thoroughly with salt black pepper and red pepper flakes if you want a little heat.
- Sear the Steak Bites:
- Heat olive oil in a large skillet over medium-high heat. When the oil shimmers add your beef in a single layer. Do not overcrowd the pan or they will steam instead of sear. Work in two batches if needed. Let the beef cook untouched for about two to three minutes per side until a deep brown crust forms.
- Make the Garlic Butter Sauce:
- Lower the heat to medium once all steak is seared. Toss in unsalted butter followed by minced garlic and a splash of Worcestershire sauce. Stir everything gently so garlic cooks but does not burn just one to two minutes until fragrant. Return all steak bits to the pan and coat well in the buttery sauce. Sprinkle with freshly chopped parsley.
- Cook and Mash the Potatoes:
- While beef is cooking peel and chop potatoes into evenly sized chunks. Place them in a large pot and cover with cold salted water. This helps potatoes cook evenly and absorb subtle salt. Bring to a boil then reduce to a steady simmer for fifteen to twenty minutes. Check with a fork they should feel soft all the way through.
- Finish the Mashed Potatoes:
- Drain cooked potatoes well and return to the hot pot to remove excess moisture. Add fresh butter whole milk or cream salt black pepper and garlic powder if using. Mash together until silky smooth. Add more milk for extra creaminess if necessary. Taste and adjust seasoning.
- Plate and Serve:
- Spoon a generous mound of mashed potatoes onto each plate. Pile on the garlic butter steak bites and spoon extra garlic butter sauce over the top. Finish with a scattering of fresh parsley to brighten the flavors and make it pop.

I absolutely love extra garlic in the butter sauce. My grandmother always insisted a generous garlic portion made the kitchen smell like home. To this day that fragrance instantly brings back memories of family gatherings around a crowded table.
Storage Tips
Store leftovers in airtight containers in the refrigerator and use within three days. To reheat mashed potatoes add a splash of milk for creamy texture before microwaving. The beef tastes best gently warmed in a skillet with a little extra butter.
Ingredient Substitutions
No sirloin or ribeye on hand Try stew beef trimmed and cut smaller or even cubed chicken thighs for a lighter version. Use ghee for the butter if you want a nutty flavor. If out of fresh parsley try using a mix of chives or a sprinkle of dill.
Serving Suggestions
These beef bites are rich enough to stand on their own yet pair beautifully with a crisp green salad. For something extra serve with roasted carrots or green beans. Sometimes I lay beef bites over toasted baguette slices for a hearty appetizer.
