Ingredients

• 1 lb (450 g) beef sirloin or flank steak, thinly sliced against the grain

• 12 oz (340 g) fresh green beans, trimmed

• 3 tablespoons unsalted butter, divided

• 5 garlic cloves, minced

• 2 tablespoons low-sodium soy sauce

• 1 tablespoon olive oil

• ½ teaspoon onion powder

• ½ teaspoon smoked paprika

• ½ teaspoon black pepper

• ¼ teaspoon salt, or to taste

• ¼ cup beef broth

• 1 teaspoon lemon juice

• 1 tablespoon chopped fresh parsley

Ingredient Notes

Beef: Sirloin and flank steak are both good choices because they cook quickly. Slice the meat thinly against the grain to make each bite easier to chew.

Green beans: Fresh green beans provide the best crisp-tender texture. Trim the ends before cooking. If using frozen green beans, thaw and pat them dry first.

Butter and garlic: Unsalted butter gives you better control over the seasoning. Fresh minced garlic provides a stronger, more rounded flavor than garlic powder.

Soy sauce: Low-sodium soy sauce adds savory depth without making the dish overly salty.

Beef broth: A small amount helps loosen the browned bits in the skillet and creates a light garlic butter coating.

How to Make One-Pan Garlic Butter Beef and Green Beans

1. Prepare the beef.

Pat the beef slices dry with paper towels. Season with onion powder, smoked paprika, black pepper, and salt. Toss to distribute the seasoning evenly.

2. Sear the beef.

Heat olive oil in a large skillet over medium-high heat. Arrange the beef in a single layer, working in batches if necessary. Sear for approximately 1–2 minutes per side, until nicely browned.

Transfer the beef to a clean plate. Avoid overcrowding the skillet, as this can cause the meat to steam instead of brown.

3. Cook the green beans.

Add 1 tablespoon of butter to the same skillet. Add the green beans and cook for 4–5 minutes, stirring occasionally.

Pour in the beef broth, cover the skillet, and cook for another 2–3 minutes. The beans should become bright green and crisp-tender rather than soft and mushy.

4. Make the garlic butter sauce.

Reduce the heat to medium. Add the remaining 2 tablespoons of butter and minced garlic. Stir for approximately 30–45 seconds, just until fragrant.

Add the soy sauce and lemon juice, stirring to combine with the melted butter and pan juices.

5. Combine everything.

Return the seared beef and any accumulated juices to the skillet. Toss gently with the green beans and garlic butter sauce.

Cook for another 1–2 minutes, allowing everything to heat through. Check that the beef has reached a safe internal temperature of 145°F, followed by a 3-minute rest.

6. Garnish and serve.

Remove the skillet from the heat. Sprinkle with fresh parsley and serve immediately while the garlic butter sauce is warm.

Expert Tips

• Slice against the grain: This shortens the muscle fibers and helps prevent chewy beef.

• Dry the beef first: Excess moisture makes browning more difficult.

• Use a large skillet: A wide skillet gives the ingredients enough room to cook evenly.

• Don’t burn the garlic: Add it after the green beans have cooked and reduce the heat. Garlic can become bitter when exposed to excessive heat.

• Keep the beans crisp-tender: Avoid cooking them for too long, especially if you prefer a little bite.

• Adjust the sauce: If the skillet looks dry, add a tablespoon of beef broth rather than extra butter.

Common Mistakes to Avoid

• Overcrowding the pan: Cook beef in batches to encourage browning.

• Using thick beef pieces: Thick pieces take longer to cook and may become unevenly done.

• Adding garlic too early: Garlic can burn while the beef is searing.

• Overcooking the green beans: They should retain some firmness.

• Adding too much salt: Soy sauce already contributes saltiness, so season gradually.

Easy Variations

• Spicy garlic butter beef: Add ¼–½ teaspoon red pepper flakes or a little chili sauce.

• Mushroom addition: Cook 1 cup of sliced mushrooms before adding the green beans.

• Broccoli version: Replace half the green beans with broccoli florets.

• Asian-inspired version: Add 1 teaspoon freshly grated ginger and finish with sesame seeds.

• Extra buttery version: Add another tablespoon of butter at the end for a richer coating.

Ingredient Substitutions

• Sirloin: Substitute flank steak, flat iron steak, or thinly sliced top round.

• Fresh green beans: Frozen green beans work, although their texture may be softer.

• Beef broth: Chicken broth or water can be used in the same quantity.

• Soy sauce: Coconut aminos can provide a similar savory note, with a slightly different flavor.

• Fresh parsley: Substitute chopped green onions for a fresh finishing touch.

What to Serve With It

This garlic butter beef and green beans skillet pairs well with:

• Steamed white rice: Absorbs the savory garlic butter sauce.

• Garlic mashed potatoes: Make the meal more filling and complement the beef.

• Egg noodles: Provide a simple base for the buttery pan juices.

• Roasted potatoes: Add a hearty texture alongside the tender beef.

• Cauliflower rice: A lighter alternative to traditional rice.

Storage & Reheating

Refrigerator: Allow leftovers to cool, then transfer them to an airtight container. Refrigerate for up to 3–4 days.

Freezing: Freezing is possible for up to 2 months, although green beans may become softer after thawing. Store in a freezer-safe container.

Reheating: Warm leftovers in a skillet over medium-low heat with 1–2 tablespoons of beef broth or water. Stir gently until heated through. Avoid prolonged heating because the beef can become tough.

For food safety, reheat leftovers to 165°F.
