Make It Your Way

- Variation: One time, I added a touch of smoked paprika to the marinade—it brought a subtle smoky depth that made this a summer favorite on the grill.
Step-by-Step: How I Make Butter-Seared Steak with Thyme Pan Sauce Recipe
Step 1: Marinate the Steak for Maximum Flavor
Start by mixing your soy sauce, olive oil, sriracha, and black pepper in a bowl. Toss in your flank steak strips and let them soak up all those spicy, salty flavors for at least 30 minutes. This step really tenderizes the meat and sets the stage for a delicious crust.
Step 2: Sear the Steak in Butter
Heat 1 tablespoon of butter in your skillet over medium-high heat. Season the steak with salt and pepper right before searing, then cook quickly—about 1 to 2 minutes per side until browned but still juicy inside. Resist the urge to move the strips around; letting them sit will get you that gorgeous crust. Remove and keep warm.
Step 3: Build the Thyme Pan Sauce
Turn your heat down to medium and toss in the shallots and garlic in the leftover butter and steak drippings. Stir occasionally until the shallots soften—about 2 minutes. Then add fresh thyme, chives, chili flakes, lemon juice, Dijon mustard, and beef stock. Use a wooden spoon to scrape up any tasty browned bits stuck to the pan. Let the sauce simmer and reduce by half, about 5 minutes, then swirl in your remaining 2 tablespoons of butter for that silky finish. Taste and adjust seasoning with salt and pepper.
Step 4: Reheat the Steak and Serve
Return the steak strips to the skillet, tossing quickly to coat them in the sauce and warm up. Garnish with freshly chopped parsley and chives. Serve right away with your favorite sides—you’ll want to dig in while it’s hot!
Top Tip
I’ve learned a few things after making this Butter-Seared Steak with Thyme Pan Sauce Recipe more times than I can count. These tips are small but make a huge difference in flavor and texture.
- Dry the Steak First: Pat your steak strips dry before marinating to help them sear properly—moisture is the enemy of a good crust.
- Don’t Skip Resting Time: Rest the steak briefly after searing on a warm plate to keep juices locked in before adding it back to the sauce.
- Use Unsalted Butter: It gives you better control over seasoning and melts more evenly into the sauce.
- Scrape the Pan Well: Deglazing with stock and scraping the bottom releases flavorful brown bits—don’t rush this step!
How to Serve Butter-Seared Steak with Thyme Pan Sauce Recipe
Garnishes
I always finish this dish with a scattering of fresh parsley and chopped chives—that fresh herb combo gives a pop of green and a subtle fresh bite that cuts through the richness.
Side Dishes
My favorites to pair: garlicky sautéed spinach or a vibrant medley of roasted potatoes, carrots, and zucchini. The earthy vegetables balance the richness, and the colors on the plate make it pop.
Creative Ways to Present
For special occasions, I've plated this steak sliced on a wooden board next to lemon wedges and small bowls of extra sauce—a simple but elegant approach that invites everyone to serve themselves and keeps the conversation flowing.
Make Ahead and Storage
Storing Leftovers
If you manage to have leftovers (rare in my kitchen!), store them in an airtight container in the fridge for up to 2 days. Keep the steak and sauce together to maintain moisture, but be mindful that the texture will soften a bit.
Freezing
I’ve frozen leftover steak strips with the sauce successfully—just make sure to cool completely before freezing in a well-sealed container. Thaw overnight in the fridge for best texture when reheating.
Reheating
Gently reheat leftover Butter-Seared Steak with Thyme Pan Sauce Recipe over low heat on the stovetop or in the microwave to avoid drying it out. Adding a splash of beef stock or water helps re-loosen the sauce.
Frequently Asked Questions:
Yes! While flank steak works beautifully due to its thinness and flavor, you can use sirloin, skirt steak, or even ribeye strips depending on what you prefer or have on hand—just adjust cooking time accordingly to avoid overcooking.
To make this recipe paleo or gluten-free, simply substitute soy sauce with coconut aminos in the marinade. This change keeps the umami flavor without gluten or soy, making it allergy-friendly and paleo compliant.
Yes, you can marinate the steak strips up to 24 hours ahead, which actually deepens the flavor. The pan sauce is best made fresh, but you can also prepare the shallot and garlic mix in advance and quickly combine ingredients when cooking.
Look for a beautiful deep brown crust with minimal movement during searing. The steak should be caramelized but still juicy inside. This usually takes about 1-2 minutes per side when using high heat. Avoid flipping multiple times to allow proper crust formation.
Final Thoughts
This Butter-Seared Steak with Thyme Pan Sauce Recipe is one I come back to again and again because it strikes that perfect balance between simple and indulgent. Each time I make it, I feel like I’m treating both myself and whoever I'm sharing it with to something a little special—without hours in the kitchen.

Ingredients
For the Steak and Marinade
- 1 lb flank steak, cut into strips
- ¼ cup soy sauce (or coconut aminos for paleo and gluten-free)
- 1 tablespoon olive oil
- 1 tablespoon Sriracha (or any hot sauce)
- Fresh cracked black pepper, to taste
For the Butter Sauce
- 1 + 2 tablespoons unsalted butter, divided
- 1 small shallot, finely chopped
- 3 garlic cloves, minced
- Pinch of red chili pepper flakes, to taste
- 1 tablespoon Dijon mustard
- 3 teaspoons minced fresh thyme
- 1 tablespoon finely minced chives
- ½ cup beef stock (or water)
- 1 tablespoon lemon juice
- Salt and fresh cracked pepper, to taste
- Fresh chopped parsley, for garnish
Instructions
- Prepare the Marinade. In a bowl, combine olive oil, Sriracha, fresh cracked black pepper, and soy sauce. Stir well and add the flank steak strips, mixing to coat thoroughly. Marinate for at least 30 minutes to allow flavors to infuse.
- Cook the Steak. Melt 1 tablespoon of butter in a skillet over medium-high heat. Remove steak from marinade and season lightly with salt and pepper. Quickly sear the steak strips in the hot butter, turning just once until browned, about 1 to 2 minutes total. Transfer the cooked steak strips to a covered plate to rest while you prepare the sauce.
- Make the Butter Sauce. Reduce the heat to medium and add the chopped shallot and minced garlic to the skillet. Cook, stirring occasionally, until the shallot is softened and fragrant, about 2 minutes. Stir in the fresh thyme, minced chives, red chili pepper flakes, lemon juice, Dijon mustard, and beef stock. Use a wooden spoon to scrape up any browned bits from the skillet. Optionally, add some of the remaining marinade to enhance flavor. Cook while swirling the pan occasionally until the liquid reduces by about half, around 5 minutes.
- Finish the Sauce and Reheat Steak. Add the remaining 2 tablespoons of butter to the skillet, swirling to melt into the sauce. Season with salt and fresh cracked pepper to taste. Return the steak strips to the pan and reheat quickly in the sauce for about 1 minute to coat the meat.
- Serve. Garnish with fresh chopped parsley and additional minced chives. Serve immediately with sautéed spinach or roasted potatoes, carrots, and zucchini for a complete meal. Enjoy!
Notes
- Marinate the steak for a minimum of 30 minutes, but up to 2 hours for more flavor penetration.
- Use coconut aminos instead of soy sauce for a gluten-free and paleo-friendly option.
- If beef stock is unavailable, water can be substituted though it will be less rich.
- Adjust chili flakes according to heat preference.
- Do not overcook the steak strips to maintain tenderness; quick searing is key.
- The butter sauce can be prepared in the same skillet right after searing to absorb all the flavors.
- Serve with your favorite sides such as sautéed greens or roasted root vegetables for a balanced meal.
