There’s a moment—right after the steak hits the cast-iron pan—when the kitchen fills with the nutty perfume of browning butter and the sweet punch of garlic. That is the moment I know dinner is about to be spectacular. I developed this recipe after a summer trip to Buenos Aires, where I fell head-over-heels for the way Argentinians treat beef: simply, reverently, and always with a bright, herbaceous chimichurri that cuts through every rich bite. Back home in Chicago, I wanted to recreate that experience for my friends during our first backyard gathering of the season. The steak was a hit, the chimichurri disappeared in minutes, and the garlic-butter spooned over the carving board was practically drunk straight from the bowl. Since then, this dish has become my go-to for birthdays, anniversaries, and any Friday that deserves a standing ovation. If you can sear butter and blitz herbs, you can master this restaurant-worthy feast—and I promise you’ll never look at steak the same way again.

Why This Recipe Works

Restaurant-quality crust: A screaming-hot cast-iron pan and a whisper-thin layer of mayonnaise create the deepest, crunchiest Maillard crust you’ve ever tasted.
Two-zone heat: Sear on the stovetop, finish in the oven—no burnt outside, raw inside, or smoke-filled kitchen.
Flavor layering: Garlic-infused butter bathes the steak while it roasts, then again as it rests, so every fiber tastes like paradise.
Make-ahead chimichurri: Whip up the sauce up to 5 days early; the herbs stay vivid thanks to a splash of red-wine vinegar “chlorophyll lock.”
Flexible cuts: Ribeye, strip, or even sirloin all shine here—no need to splurge on filet unless you want to.
One-pan elegance: Sear, roast, rest, and serve from the same skillet, capturing every last drop of garlicky gold.
Impressive yet fast: 15 minutes of active time, 30 minutes total, and zero advanced techniques—perfect for weeknight luxury or date-night decadence.

Ingredients You'll Need

Great steak starts at the butcher counter. Look for 1 ¼–1 ½ inch thick cuts with abundant marbling; the fat equals flavor and juiciness. I prefer boneless ribeye for its generous intramuscular fat, but New York strip is equally luxurious and cooks slightly faster. If sustainability matters to you, seek out grass-fed, grain-finished beef—it offers the best balance of earth-friendly practices and buttery tenderness.

For the garlic butter, reach for European-style butter with 82–84 % fat; the higher fat content means less water and more browning power. Use fresh garlic rather than pre-minced; the volatile compounds that deliver that sweet, nutty aroma dissipate quickly once cut. A micro-plane grater turns cloves into a paste that melts instantly into the butter.

Chimichurri loves flat-leaf parsley; curly can taste grassy and bitter. Cilantro is optional but authentic—use the leaves and tender stems for maximum brightness. Always hand-chop or pulse gently in a food processor; a blender turns herbs black and muddy. Red-wine vinegar adds requisite tang, but a 50/50 blend with sherry vinegar layers complexity. Good-quality extra-virgin olive oil should taste fruity and peppery on its own—cheap oil will flatten the sauce. Crushed red-pepper flakes give gentle heat; feel free to sub Aleppo or smoked paprika for a twist.

Finally, grab a heavy cast-iron skillet. Its heat retention is unmatched, giving you that steak-house crust no stainless or non-stick pan can rival. If you don’t own one, any thick, oven-safe pan works—just extend oven time by a minute or two.

How to Make Garlic Butter Steak with Chimichurri for a Flavorful Feast

Dry-brine & temper

Pat steaks very dry with paper towels. Season both sides generously with kosher salt (about ½ tsp per side). Set on a wire rack over a sheet pan and let stand at room temperature 30–45 minutes. This dry-brine seasons the meat deeply and jump-starts crust formation.

Make the chimichurri

In a medium bowl combine 1 cup finely chopped flat-leaf parsley, ¼ cup chopped cilantro, 3 minced garlic cloves, ½ tsp crushed red-pepper, 1 tsp dried oregano, 2 Tbsp red-wine vinegar, 1 Tbsp sherry vinegar, ½ tsp kosher salt, and several grinds black pepper. Whisk in ½ cup extra-virgin olive oil until emulsified. Taste and adjust salt or acid. Cover and set aside to let flavors marry.

Preheat oven & pan

Place rack in center of oven and heat to 400 °F (204 °C). Heat a 12-inch cast-iron skillet over high heat until a drop of water evaporates in 1 second, about 4 minutes. You want the pan scorching for an instant crust.

Mayonnaise sear trick

Lightly brush both sides of steaks with 1 tsp mayonnaise per side. The mayo acts as a protein emulsion, encouraging even browning and preventing sticking. Don’t worry—you won’t taste it.

Sear

Lay steaks away from you into the dry pan; they should sizzle aggressively. Sear 2 minutes without moving. Flip and sear the second side 2 minutes. A deep walnut crust should form.

Add garlic butter

Reduce heat to medium. Add 4 Tbsp unsalted butter, 3 smashed garlic cloves, and 2 sprigs fresh thyme to pan. Tilt pan and baste steaks with the foaming butter for 1 minute.

Oven finish

Transfer skillet to oven. Roast 4–6 minutes for medium-rare (125 °F / 52 °C), or until desired doneness. Remove 5 degrees shy of target as temperature will rise while resting.

Rest & glaze

Move steaks to a cutting board. Pour pan juices (including garlic cloves) over top. Tent loosely with foil and rest 8–10 minutes. This relaxes proteins and redistributes juices.

Slice & serve

Using a sharp knife, slice steak against the grain into ¼-inch thick pieces. Arrange on a platter, drizzle with any remaining garlic butter, and spoon chimichurri over or alongside for vibrant contrast.

Expert Tips

Use an instant-read thermometer

Guessing doneness leads to over-cooking. Insert probe through the side into the center. Pull at 120 °F for rare, 125 °F for medium-rare, 135 °F for medium.

Dry = crust

Moisture is the enemy of browning. After unwrapping, place steaks on a rack in the fridge, uncovered, up to 24 hours. The surface will dry further, guaranteeing a steak-house crust.

Don’t crowd the pan

Over-cooling the surface causes gray, steamed meat. If doubling the recipe, sear in batches or use two skillets.

Rest on a rack

Resting directly on a plate traps steam and softens the crust. Elevate on a rack so air circulates, maintaining crunch.

Save the infused butter

Strain and refrigerate the garlicky butter. It’s liquid gold for scrambled eggs, roasted potatoes, or brushing on grilled bread.

Slice on the bias

A 45 ° angle increases surface area, ensuring every bite has more caramelized edges to dunk in chimichurri.

Variations to Try

Herb swap: Swap parsley + cilantro for basil + mint for a Mediterranean twist.
Spicy chimichurri: Add 1 seeded Fresno chile or 1 tsp smoked chipotle powder for heat and depth.
Citrus lift: Whisk 1 tsp finely grated lemon zest and 1 Tbsp juice into finished chimichurri for a sunny punch.
Compound butter upgrade: Stir 1 Tbsp crumbled blue cheese and 1 tsp chopped chives into the garlic butter for the final baste.
Surf & turf: Top steaks with 3 grilled shrimp per plate during the last minute of oven time for an elegant twist.
Vegan option: Replace steak with thick cauliflower steaks, sear 3 minutes per side, oven-roast 10 minutes, and finish with the same garlic-butter basting using plant-based butter.

Storage Tips

Leftover steak: Cool completely, refrigerate in an airtight container up to 4 days. Reheat gently in a 250 °F oven for 10–12 minutes, or slice cold for salads and sandwiches.

Chimichurri: Store covered in the refrigerator up to 5 days. Bring to room temperature and re-whisk before serving; the olive oil may solidify. Freeze in ice-cube trays up to 3 months, then pop a cube onto hot steak for instant flavor.

Garlic butter: Refrigerate in a sealed jar up to 1 week or freeze in 1-Tbsp portions up to 3 months.

Make-ahead: Season steaks the night before; refrigerate uncovered. Prepare chimichurri while your morning coffee brews; dinner will feel effortless.

Frequently Asked Questions

Absolutely. Preheat grill to high, clean and oil grates. Sear steaks directly over flames 2 minutes per side with lid open, then move to indirect heat, close lid, and cook 4–6 minutes more until desired doneness. Baste with garlic butter during the last minute.

Skip the oven. Simply sear 1 ½ minutes per side over high heat, reduce heat to medium, add butter, and baste 1 minute more. Pull at 120 °F for medium-rare; total cook time about 4 minutes.

Traditional recipes carry mild heat from crushed red-pepper. You can omit it entirely or add extra for more kick. Kids usually love the herby freshness when heat is kept minimal.

Fresh herbs are essential for the bright, zippy character of chimichurri. In a pinch, use 2 Tbsp dried parsley + 1 Tbsp dried cilantro, but rehydrate in 1 Tbsp warm water for 10 minutes before mixing. The flavor will be earthier and less vibrant.

Resting allows juices to redistribute. Cut too early and those flavorful liquids flood the board instead of staying inside each slice. Ten minutes is the sweet spot for steaks up to 1 ½ inches thick.

Yes. Cool completely, wrap tightly in foil then place in a freezer bag, removing as much air as possible. Freeze up to 3 months. Thaw overnight in the refrigerator and reheat gently as described above.
