This garlic butter steak bites recipe transforms affordable sirloin into a restaurant-quality meal that's ready in under 30 minutes. The combination of tender steak and crispy potatoes bathed in fragrant garlic butter creates a one-pan dinner that's both impressive and practical.
I first made this dish when I needed a quick dinner that would impress my in-laws without keeping me in the kitchen all evening. The empty plates and requests for seconds told me everything I needed to know.
Ingredients
Sirloin steak delivers excellent flavor while remaining tender when properly cooked. Look for cuts with good marbling for the best results.
Baby potatoes hold their shape during cooking and develop a wonderful crispy exterior. Choose ones similar in size for even cooking.
Unsalted butter allows you to control the salt level while providing rich flavor. European-style butter with higher fat content elevates this dish.
Fresh garlic provides aromatic depth that powdered versions simply cannot match. Select firm bulbs with tight skin.
Olive oil helps prevent the butter from burning while adding its own subtle flavor notes.
Italian seasoning brings herbaceous complexity without requiring multiple spice bottles. A quality blend should include basil, oregano, rosemary, and thyme.
Fresh parsley brightens the dish with color and fresh flavor. The flat-leaf variety offers more robust flavor than curly parsley.
Step-by-Step Instructions
- Prepare the potatoes.
- Wash potatoes thoroughly under cold water to remove any dirt. Cut them into halves or quarters depending on size, aiming for uniform pieces about 1-inch across. Pat them completely dry with paper towels to ensure they crisp properly rather than steam.
- Cook the potatoes.
- Heat your largest skillet over medium heat before adding olive oil and butter. Once the butter stops foaming, add the potatoes cut-side down. Season generously with salt, pepper, and Italian seasoning. Allow them to cook undisturbed for 5 minutes before turning. Continue cooking for about 15 minutes total, turning occasionally until all sides are golden brown and a fork easily pierces the flesh.
- Prepare the steak.
- While potatoes cook, cut sirloin into even 1-inch cubes. Pat them thoroughly dry with paper towels to promote browning. Season generously with salt and pepper on all sides, pressing the seasonings into the meat.
- Sear the steak.
- After removing potatoes, increase heat to medium-high and add remaining olive oil to the pan. Once the oil is shimmering but not smoking, add steak pieces in a single layer without overcrowding. Work in batches if necessary. Let them sear undisturbed for 2 minutes before turning to brown all sides. The entire cooking process should take only 4-5 minutes for medium-rare.
- Create the garlic butter sauce.
- Reduce heat to medium-low and add remaining butter and minced garlic to the empty skillet. Stir constantly for 30 seconds until the garlic becomes fragrant but not brown. This brief cooking mellows garlic's sharpness while releasing its essential oils.
- Combine and finish.
- Return the potatoes and steak to the skillet, including any accumulated juices. Gently toss everything to coat in the garlic butter sauce for about 1 minute. Remove from heat and sprinkle with fresh parsley just before serving to preserve its bright color and flavor.

My secret ingredient is a splash of Worcestershire sauce added to the garlic butter. I discovered this trick during a camping trip when I was trying to recreate steakhouse flavors with minimal ingredients. The umami depth it adds completely transforms the sauce without anyone being able to identify what makes it so special.
Perfect Steak Temperature
Achieving the ideal doneness for your steak bites requires attention to timing and visual cues. For medium-rare, look for a sear on the outside with a pinkish-red center, typically reached after 2 minutes per side. Medium doneness shows a pink center and requires about 3 minutes per side. For medium-well with just a hint of pink, aim for 4 minutes per side. Remember that steak continues cooking slightly after removing from heat, so pull it slightly before your desired doneness.
Clever Substitutions
This recipe welcomes adaptations based on what you have available. Ribeye or New York strip can replace sirloin for a more luxurious meal. Sweet potatoes offer a nutritious alternative to baby potatoes, though they'll cook faster so adjust timing accordingly. Rosemary can stand in for Italian seasoning, providing a woodsy aroma that pairs beautifully with steak. For a dairy-free version, use ghee or additional olive oil instead of butter.
Serving Suggestions
Transform this main dish into a complete meal with thoughtful accompaniments. A simple arugula salad dressed with lemon juice and olive oil cuts through the richness. Roasted asparagus or green beans add color and nutrition while complementing the garlic flavors. For special occasions, serve alongside a bold red wine like Cabernet Sauvignon or Malbec that stands up to the steak's robust flavor profile.
Storage and Reheating
Properly stored leftovers maintain their quality for impressive next-day meals. Store in an airtight container in the refrigerator for up to 3 days. When reheating, use a skillet over medium-low heat rather than a microwave to preserve texture. Add a small pat of butter to refresh the sauce. For meal prep, undercook the steak slightly since it will continue cooking during reheating.
Recipe FAQs
- → What cut of steak works best for this dish?
Sirloin is ideal as it offers good flavor and tenderness while remaining budget-friendly. Ribeye or New York strip would be excellent premium alternatives. For a more economical option, chuck steak can work well if cut against the grain and not overcooked.
- → Can I prepare the potatoes and steak in advance?
You can prepare the potatoes up to a day ahead - just cook them until almost tender, then refrigerate. For the steak, it's best cut right before cooking to maintain juiciness, though you can season it a few hours ahead and keep refrigerated.
- → How do I prevent the steak from becoming tough?
Three key steps: 1) Ensure the steak is at room temperature before cooking, 2) Use high heat to quickly sear the outside while keeping the inside juicy, and 3) Don't overcrowd the pan - cook in batches if necessary to maintain proper temperature.
- → What can I serve with garlic butter steak bites?
While this is a complete meal on its own, it pairs beautifully with simple sides like a fresh green salad, steamed broccoli, or roasted asparagus. For a more substantial meal, crusty bread is perfect for soaking up the garlic butter sauce.
- → Can I substitute the butter for a dairy-free alternative?
Yes, plant-based butter alternatives work well. Olive oil can also be used, though the flavor profile will change slightly. To maintain richness, add a splash of beef broth when using oil instead of butter.
- → How do I know when the steak bites are perfectly cooked?
For medium-rare, sear 2-3 minutes total with the center remaining pink and juicy. For medium, cook 3-4 minutes total. Using the touch test helps - medium-rare feels like the base of your thumb when touching thumb and index finger together.
