Garlic butter beef bites served over creamy mashed potatoes became a regular in my kitchen on nights when comfort and big flavor are all that matter. The sizzle of beef caramelizing in garlicky butter gets everyone hovering in the kitchen. Creamy, fluffy potatoes make the perfect base for soaking up every last bit of sauce. This recipe pulls together fast enough for busy weeknights yet always feels worthy of a special occasion.
When I first made this, my husband went quiet after the first bite and just gave me a thumbs-up. Now it is the dish everyone asks for on their birthday.
Ingredients
- Beef steak such as sirloin or ribeye: Adds tender juicy bite. Choose one with good marbling for best flavor
- Olive oil: Helps get a beautiful sear on the beef. Go for extra virgin for depth
- Unsalted butter: Forms the base of the garlic sauce. Use good quality for richer taste
- Fresh garlic: Delivers aromatic punch and depth. Freshly minced is best
- Salt and black pepper: Essential for enhancing natural flavor. Use kosher salt and cracked pepper if possible
- Red pepper flakes: Offers gentle heat. Optional if you like a little spice
- Worcestershire sauce: Boosts umami and savoriness. Just a splash makes a difference
- Fresh parsley: Brightens up the final dish. Chop it fresh for maximum flavor
- Russet or Yukon gold potatoes: Make the mashed base. Yukon yields a creamier mash but russets are fluffy
- Whole milk or heavy cream: Adds richness and creaminess. Use whole milk for lighter texture or cream for extra lushness
- Garlic powder: Adds subtle background flavor. Optional but highly recommended
- Fresh parsley for garnish: Gives that finishing touch sprinkled on top
Step-by-Step Instructions
- Prep the Beef:
- Let steak sit out on the counter for about twenty minutes to lose its chill. This helps it cook evenly. Pat dry with paper towels until completely moisture free. Cut into one inch cubes and season thoroughly with salt, black pepper, and red pepper flakes if you like a touch of spice.
- Prep the Potatoes:
- While the beef comes to temperature, peel and chop potatoes into even sized chunks. Place them in a pot, cover with cold water, and add a good pinch of salt. Starting with cold water allows for even cooking. Bring the pot to a boil over high heat.
- Sear the Beef:
- Heat olive oil in a large skillet over medium high heat until the oil is hot and shimmering. Add beef cubes in a single layer, be careful not to overcrowd. Let them cook undisturbed for two to three minutes per side. This creates a flavorful brown crust. Work in batches if your pan is not big enough.
- Make the Garlic Butter:
- Once beef has a golden sear on all sides, lower the heat to medium. Add butter to the pan and allow it to melt and become foamy. Add minced garlic and a splash of Worcestershire sauce. Stir everything for about one to two minutes until the kitchen smells amazing but before the garlic browns. Toss beef so every piece is well coated in the butter.
- Mash the Potatoes:
- When potatoes are fork tender after about fifteen to twenty minutes of simmering, drain them very well. Return to the hot pot. Add butter, milk or cream, a bit more salt and pepper, and garlic powder if using. Mash to your desired texture. Add more milk a splash at a time if you like things extra silky.
- Serve:
- Pile a big scoop of mashed potatoes on each plate. Top with juicy garlic butter beef bites. Pour any extra sauce from the pan right over the top and finish with a sprinkle of fresh parsley for freshness and color.

My favorite part is the way fresh parsley cuts through the richness, brightening every bite. I will never forget watching my dad mop up every last bit of sauce with bread after a family Sunday dinner. The buttery garlic and juicy beef always steal the show.
Storage Tips
Leftovers keep well in an airtight container in the fridge for up to three days. For best results, store beef and potatoes separately and reheat potatoes with a splash of milk to restore creaminess. The beef can be gently reheated in a skillet with a touch more butter to keep it juicy. Mashed potatoes are safe to freeze if you want to make a batch ahead, but they are at their creamiest fresh from the pot.
Ingredient Substitutions
You can swap sirloin or ribeye for other well marbled cuts like strip steak. If you want to keep it lean, try beef tenderloin. For dairy free, use vegan butter and unsweetened oat milk in the potatoes. If parsley is not on hand, chives or green onions also add a nice fresh pop. For the mashed potatoes, Yukon golds make for the smoothest mash and bring a naturally buttery flavor.
Serving Suggestions
Pair this meal with a crisp side salad or simply steamed green beans for a pop of color and a little crunch. A piece of crusty bread will not go amiss for sopping up the garlicky sauce. The beef bites also make a delicious party nibble served on toothpicks with the sauce as a dip. For a family dinner, this is comfort food in its purest form.
