Ingredients & Why They Work
These ingredients are the magic behind that tender steak and herby butter sauce. The marinade packs umami and heat while the fresh herbs and lemon juice add brightness that cuts through the richness perfectly.
- Flank steak: Its thin, lean profile makes it perfect for quick marinating and searing; slice it against the grain for tenderness.
- Unsalted butter: Essential for controlling salt levels and creating a silky sauce base.
- Shallot: Adds a mild onion sweetness that becomes tender and fragrant when sautéed.
- Garlic: For that punch of aromatic depth you want in any good pan sauce.
- Red chili pepper flakes: Adjustable heat to kick the sauce up a notch without overwhelming the other flavors.
- Dijon mustard: Provides a subtle tang and complexity in the sauce's flavor profile.
- Fresh thyme and chives: Earthy and bright herbs that complement the richness of butter and beef.
- Beef stock: Adds a hearty, savory base to the sauce; can substitute with water in a pinch.
- Lemon juice: Balances the butter's richness with fresh acidity.
- Soy sauce (or coconut aminos): Brings salty umami and depth to the marinade.
- Olive oil: Helps carry the marinade flavors and prevents sticking during searing.
- Sriracha (or preferred hot sauce): Adds smoky heat and a touch of sweetness.
- Fresh parsley: Used as garnish, giving a fresh herbal note and vibrant color.
Make It Your Way
I absolutely love tweaking this Pan-Seared Steak with Herb Butter Sauce Recipe, especially the marinade and herbs depending on the seasons or my mood. You should feel free to play around with it too—cooking should always be a bit of fun!
- Variation: Sometimes, I swap out flank steak for skirt steak or sirloin based on what’s fresh at the market—just adjust your sear time slightly. And if you prefer lower spice levels, I cut back on the chili flakes and Sriracha, which keeps it approachable for everyone at the table.
Step-by-Step: How I Make Pan-Seared Steak with Herb Butter Sauce Recipe
Step 1: Marinate the Steak for Maximum Flavor
Start by mixing your soy sauce, olive oil, Sriracha, and pepper in a bowl, then toss in the steak strips. I usually let them soak up the marinade for at least 30 minutes—longer if you have the time—so each bite is bursting with that umami and spicy kick. It’s totally worth the wait.
Step 2: Sear Quickly for a Beautiful Crust
Heat 1 tablespoon of butter in your skillet over medium-high heat until it’s nicely melted and shimmering. Season the marinated steak lightly with salt and pepper, then sear the strips in batches. You want a quick, hot sear—about 1 to 2 minutes per side—until they develop that golden crust. Avoid overcrowding the pan so you get a nice sear, not a steamed mess. Transfer the strips to a warm plate and loosely cover to keep warm.
Step 3: Build the Herb Butter Sauce
Lower the heat to medium and add the shallot and garlic to the same pan. Stir to soften and release those inviting aromas—2 minutes is perfect. Next, add fresh thyme, chives, chili flakes, lemon juice, and Dijon mustard. Pour in the beef stock and use your wooden spoon to scrape up all those flavorful browned bits stuck to the pan—that's pure gold right there. Let it simmer and reduce by about half, roughly 5 minutes, creating a rich, glossy sauce. Finish by swirling in the remaining 2 tablespoons of butter for silkiness, then season with salt and pepper to taste.
Step 4: Bring It All Together
Return the steak strips to the pan for a quick reheat in the luscious herb butter sauce—just a minute or so is enough. Plate everything up, sprinkle fresh parsley and a bit more chives on top, and you’ve got a dish that looks and tastes like you spent hours fussing over it (but really didn’t!).
Top Tip
Through many pan-seared steak sessions, I’ve learned that the sauce is where you really wow your guests, so don’t skip those browned bits or the final swirl of butter—it makes a night-and-day difference.
- Patience with Marinade: Give the meat enough time to marinate; it really amplifies the taste beyond just seasoning.
- Hot Pan, But Not Smoking: A super hot pan is your friend, but watch it closely! Butter can burn quickly, so medium-high is my sweet spot.
- Use a Wooden Spoon for Deglazing: Scraping up the bits left behind builds your sauce’s flavor. Don’t be shy about it!
- Slice Against the Grain: This little trick keeps the steak super tender and easier to chew.
How to Serve Pan-Seared Steak with Herb Butter Sauce Recipe
Garnishes
I’m a sucker for the pop of fresh parsley and extra chopped chives on top—they add freshness and a lovely green color that makes this dish pop on the plate. Sometimes I add a lemon wedge too, for anyone who wants an extra zing.
Side Dishes
My go-to sides right now are sautéed spinach with garlic or a medley of roasted potatoes, carrots, and zucchini. The earthy veggies balance the richness of the sauce perfectly and keep the meal feeling hearty but not heavy.
Creative Ways to Present
For a dinner party, I love plating the steak strips fanned out over a smear of creamy mashed potatoes, then spooning the herb butter sauce on top like a glossy finish. It makes everything look elegant without the stress. Fresh herb sprigs or edible flowers can also add that restaurant-style wow factor.
Make Ahead and Storage
Storing Leftovers
If you have leftovers (and who doesn’t?), store them in an airtight container in the fridge within two hours of cooking. The sauce keeps the steak moist and flavorful even after reheating.
Freezing
Freezing is possible but not ideal for the best texture, especially with the butter sauce. If you must, freeze steak and sauce separately in well-sealed containers and thaw overnight in the fridge before reheating gently.
Reheating
Warm leftovers in a skillet over low heat, stirring gently to avoid overcooking the steak. Adding a splash of water or broth can help loosen the sauce and keep everything silky.
Frequently Asked Questions:
Absolutely! Skirt or sirloin steak both work well with this method. Just watch the sear time as thinner cuts will cook faster.
Since the steak is thinly sliced strips, a quick 1-2 minute sear on each side usually results in medium-rare to medium. If you prefer it more done, just add a bit more time but be careful not to overcook.
You can prepare the herb butter sauce ahead and gently reheat when ready to serve, but it tastes best freshly made right after searing the steak.
Roasted or sautéed vegetables like spinach, carrots, zucchini, or potatoes complement this steak beautifully and help balance the richness of the butter sauce.
Final Thoughts
This Pan-Seared Steak with Herb Butter Sauce Recipe is one of those dishes that feels special but is truly easy enough for any night. For me, it’s the sauce that steals the show and the quick marinade that packs all the savory, spicy, and tangy notes I crave. I recommend you try this at home—it’s a guaranteed way to impress yourself and anyone lucky enough to share your table.

Description
This Pan-Seared Steak in Butter Sauce is a quick and flavorful dish featuring tender flank steak strips marinated in a spicy soy-based sauce, then seared to perfection and served with a rich, aromatic butter sauce infused with shallots, garlic, fresh herbs, and a hint of chili. Ideal for an impressive yet easy dinner, it pairs wonderfully with sautéed spinach or roasted vegetables.
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
- Marinate the Steak: In a bowl, whisk together olive oil, Sriracha, black pepper, and soy sauce. Add the flank steak strips and coat evenly. Cover and let marinate for at least 30 minutes to infuse flavor.
- Cook the Steak: Heat 1 tablespoon of butter in a skillet over medium-high heat. Season the marinated steak strips with salt and pepper, then sear quickly, turning just once, until browned, about 1 to 2 minutes. Remove the steak from the skillet, transfer to a covered plate, and set aside.
- Prepare the Butter Sauce: Reduce heat to medium. In the same skillet, add the finely chopped shallot and minced garlic. Cook, stirring occasionally, until the shallot is softened and fragrant, approximately 2 minutes. Stir in fresh thyme, chives, red chili flakes, lemon juice, Dijon mustard, and beef stock. Use a wooden spoon to scrape up any browned bits from the skillet. Optionally add the remaining marinade for extra flavor. Cook the sauce, swirling the pan occasionally, until the liquid reduces by half, about 5 minutes.
- Finish the Sauce and Reheat Steak: Add the remaining 2 tablespoons of butter to the skillet and swirl until melted, enriching the sauce. Taste and adjust seasoning with salt and fresh cracked pepper.
- Combine and Serve: Return the seared steak strips to the pan and reheat quickly in the butter sauce. Garnish with chopped parsley and additional chives. Serve immediately with sautéed spinach or roasted potatoes, carrots, and zucchini as desired. Enjoy your flavorful pan-seared steak in butter sauce!
Notes
- Marinating the steak for longer (up to 2 hours) will enhance the flavor more deeply.
- You can substitute flank steak with skirt steak or sirloin strips for similar results.
- For a paleo and gluten-free option, use coconut aminos instead of soy sauce.
- To make the sauce vegetarian, replace beef stock with mushroom broth and omit the steak.
- If you like more heat, increase the amount of chili flakes or Sriracha in the marinade.
- Serve with sides like sautéed spinach or roasted mixed vegetables for a balanced meal.
