Steakhouse dinners usually mean a reservation, a babysitter, and a bill that makes you blink. These garlic butter steak bites skip all of that. Sirloin cubes seared hard until deeply crusted, crisp-tender green beans, and a foaming garlic-butter pan sauce that coats every bite — all in one skillet, in 30 minutes, on a Tuesday.
Why you’ll love it
- Steakhouse crust, home kitchen. Bite-size cubes mean maximum browned surface — more crust per bite than any steak you could slice.
- Genuinely 30 minutes. The steak sears in two quick batches while the beans blanch; everything lands on the table at once.
- ~38g protein per serving (estimated), from sirloin plus a little butter and garlic.
- One skillet. Sear, sauté, and sauce without washing a second pan.
Ingredients
- 1 1/2 lb top sirloin steak, cut into 1-inch cubes
- 1 tsp kosher salt, divided, plus more to taste
- 3/4 tsp black pepper, divided
- 1 1/2 lb green beans, trimmed
- 3 tbsp olive oil, divided
- 5 cloves garlic, minced
- 4 tbsp unsalted butter
- 1 tsp fresh thyme leaves, or 1/2 teaspoon dried
- 1/2 tsp crushed red pepper flakes, optional
- 2 tbsp chopped fresh parsley, for serving
- Lemon wedges, for serving
Equipment
A large skillet (12-inch), preferably cast iron or stainless steel, tongs, and a slotted spoon.
Instructions
- Prep the steak and beans. Pat the steak cubes very dry with paper towels — moisture is the enemy of browning. Season with 3/4 teaspoon of the salt and 1/2 teaspoon of the pepper. Trim the green beans and cut any long ones in half.
- Blanch the beans. Bring a medium pot of salted water to a boil. Add the green beans and cook 2–3 minutes until bright green and crisp-tender. Drain and set aside. This par-cook means they only need a finishing sear later.
- Sear the steak hard. Heat 2 tablespoons of the olive oil in the large skillet over high heat until just smoking. Add half the steak cubes in a single layer — do not crowd them — and sear undisturbed for 2 minutes, then flip and sear 1–2 minutes more until deeply browned on the outside. Transfer to a plate. Repeat with the remaining oil and steak.
- Char the beans. Reduce the heat to medium-high. Add the blanched beans to the skillet with the remaining 1/4 teaspoon salt and 1/4 teaspoon pepper. Cook, stirring occasionally, 2–3 minutes until they pick up blistered spots. Transfer to the plate with the steak.
- Build the garlic butter. Reduce the heat to medium-low. Melt the butter in the skillet, then add the garlic, thyme, and red pepper flakes if using. Cook, stirring constantly, 1–2 minutes until the garlic is fragrant and pale gold at the edges — not brown, which tastes bitter.
- Bring it all together. Return the steak and beans (plus any juices from the plate) to the skillet and toss in the foaming garlic butter until everything glistens, 1–2 minutes. The residual heat finishes the steak while the butter coats every bite. Shower with parsley and serve immediately with lemon wedges.
Doneness cues: The steak cubes are seared to a deep brown crust on the outside; for food safety, steak only needs to reach 145°F internally followed by a 3-minute rest (per USDA guidance) — medium doneness beyond that is a preference, not a rule. The beans are done when blistered at the edges but still bright green and crisp-tender inside.

Substitutions and tips
- Ribeye works beautifully — richer, more marbling, same method. Flank steak cut against the grain in strips is a budget-friendly swap.
- Don’t skip patting dry. Surface moisture steams the beef instead of searing it — the single biggest difference between gray and gorgeous steak bites.
- Two batches are non-negotiable. Crowded steak never browns. Six inches of breathing room around each cube is the rule of thumb.
- Keep the garlic moving. Minced garlic goes from golden to bitter in under a minute — stir constantly and pull it at pale gold.
- Dairy-free: use a neutral oil and finish with extra lemon and herbs instead of butter.
- Make it a meal: serve over mashed potatoes, rice, or crusty bread to catch the garlic butter.
Storage and reheating
Refrigerate leftovers within 2 hours in an airtight container for up to 3 days. Reheat gently in a skillet over medium-low heat just until steaming (145°F for the steak) — high heat will overcook the cubes and toughen them. Freezing is not recommended; the steak turns rubbery and the beans go limp.
Frequently asked questions
Can I use a different cut of steak? Yes — ribeye for richness, or flank/skirt cut against the grain into strips. Avoid pre-tenderized or very lean cuts like eye of round, which dry out fast in a hot skillet.
How do I know when the steak is done? Look for a deep brown crust on at least two sides of each cube. For food safety, steak needs 145°F internal followed by a 3-minute rest (USDA); medium doneness is a preference, not a safety requirement.
Can I cook the beans in the same pan without blanching? You can, but it takes longer and the beans come out oily rather than blistered. Blanching first is the 3-minute trick that keeps this a 30-minute dinner.
Will this work on a gas vs. electric stove? Both, but the key is a ripping-hot pan. On electric, give the skillet an extra 2–3 minutes of preheat so it holds its heat when the steak hits it.
Is this good for meal prep? The steak is at its best fresh — reheating inevitably takes it past the original doneness. If prepping, slightly undercook the cubes and eat within 2–3 days.
