• 1/2 cup (125ml) low-sodium beef stock

• 1/2 cup fresh chopped parsley

• 1 tablespoon fresh thyme leaves

Pro Tips

These three techniques make all the difference between a good skillet meal and an unforgettable one.

Slice the steak correctly. Always cut flank steak against the grain. This shortens the muscle fibers, making every bite noticeably more tender. Look closely at the direction the lines run across the meat and slice perpendicular to them.

Do not overcrowd the pan. When searing the steak strips, lay them in a single layer with space between each piece. Overcrowding causes steaming rather than browning, and you will lose that beautiful caramelized crust that adds so much depth to the final dish.

Pre-cook the green beans. Microwaving the green beans until almost done before adding them to the skillet ensures they finish perfectly in the sauce without overcooking. They soak up the garlic butter and pan juices beautifully while keeping their color and slight crunch. This step makes timing the entire dish much easier.

Instructions

Step 1:
In a large bowl, combine the steak strips with soy sauce, olive oil, pepper, and hot sauce. Set aside to marinate for 10 minutes while you prepare green beans.

Step 2:
While meat is marinating, arrange green beans in a microwave-safe dish with 1/2 cup (125ml) water. Cook in the microwave for 8-10 minutes, until almost done but still crisp.

Step 3:
Melt 2 tablespoons butter in a large skillet over medium-high heat. Lay the steak strips in one layer in the skillet, keeping the drained marinade for later. Sear for 1 minute on one side, until nicely browned. Add half the garlic and red chili pepper flakes and turn the steak strips to finish cooking for one minute more – adjust timing depending on how you like your steak. Transfer steak strips to a plate and set aside.

Step 4:
In the same skillet, lower the heat and melt the remaining tablespoon of butter. Add chopped parsley, thyme, remaining garlic, Italian seasoning, red crushed chili pepper flakes, and pre-cooked green beans and cook for 4 to 5 minutes, stirring regularly, until cooked to your liking. Deglaze with lemon juice, beef stock, and reserved steak marinade, and reduce the sauce for a couple of minutes.

Step 5:
Add grilled steak strips back to the pan and reheat quickly. Adjust seasoning with pepper and serve the garlic butter steak and lemon green beans skillet immediately, garnished with more crushed chili pepper, fresh herbs, and a slice of lemon if you like. Enjoy!

Variations

This flexible recipe adapts beautifully to different tastes and dietary needs.

Swap the protein. Chicken breast or thighs sliced into strips work wonderfully in place of flank steak. Simply adjust the cooking time to ensure the chicken cooks through fully. The garlic butter sauce complements poultry just as beautifully as it does beef.

Try a low-sodium, paleo-friendly version. Replace the soy sauce in the marinade with coconut aminos for a completely paleo-compliant garlic butter steak skillet. The flavor is slightly sweeter but equally delicious and satisfying.

Add extra vegetables. Bell peppers, mushrooms, or zucchini make excellent additions to bulk out this dish. Toss them into the skillet alongside the green beans and cook until tender. This is a wonderful way to add color, nutrition, and variety to the meal.

Storage and Serving

Storing leftovers: Allow the Garlic Butter Steak and Green Beans to cool completely before transferring it to an airtight container. Refrigerate for up to three days. Reheat gently in a skillet over low heat, adding a small splash of beef stock to loosen the sauce and prevent the steak from drying out. Avoid microwaving on high heat, as this can toughen the steak strips quickly.

Serving suggestions: This dish is satisfying enough to serve entirely on its own as a complete low-carb meal. For a heartier dinner, pair it with fluffy white rice, creamy mashed potatoes, or buttered egg noodles to soak up every drop of that incredible garlic butter sauce. A simple green salad or crusty bread on the side rounds out the meal perfectly for a crowd-pleasing dinner spread.

FAQs

Can I use a different cut of steak?
Yes. Skirt steak, sirloin, or ribeye all work well in this recipe. Flank steak is preferred because it is lean, affordable, and slices beautifully against the grain, but any tender cut will deliver great results.

Can I cook the green beans on the stovetop instead of the microwave?
Absolutely. Blanch the trimmed green beans in boiling salted water for 3 to 4 minutes, then drain and proceed with the recipe as directed. The microwave method is simply faster and more convenient on busy weeknights.

How do I know when the steak is cooked to my liking?
For medium-rare, sear each side for about one minute as directed. For medium, add 30 seconds per side. Use a meat thermometer if needed: 130°F for medium-rare and 145°F for medium.

Is this Garlic Butter Steak and Green Beans recipe gluten-free?
Use tamari or certified gluten-free soy sauce in place of regular soy sauce to make this recipe fully gluten-free. All other ingredients are naturally gluten-free.

Can I make this recipe ahead of time?
You can marinate the steak and pre-cook the green beans up to one day in advance. Store them separately in the refrigerator and complete the skillet cooking fresh when you are ready to serve for the best texture and flavor.
