3 Classic Steak Sauces Every Chef Needs: Garlic-Herb Butter, Peppercorn, and Chimichurri

Chef’s Overview

Dear Chefs, if you read our last blog on A Great Steak Frites Recipe – The Pro Chefly Way, you know I couldn’t resist hinting at a few sauces that take steak from great to unforgettable. Well, here they are. Today, we’re diving into three classics every chef should master: a silky garlic-herb butter, a bold peppercorn sauce, and a vibrant chimichurri. These aren’t just sauces—they’re flavor stories that bring out the very best in your steak.

Garlic-Herb Butter: The Golden Touch

I’ll start with the simplest, because sometimes elegance is a pat of butter melting over a perfectly seared steak. Garlic-herb butter is the sauce that isn’t really a sauce—it’s a finishing flourish that whispers luxury without trying too hard.

You’ll need:

• 1 stick (½ cup) unsalted butter, softened

• 2 cloves garlic, finely minced

• 1 tablespoon fresh parsley, chopped

• 1 teaspoon fresh thyme leaves

• Pinch of sea salt & black pepper

Steps:

1. In a small bowl, mash the softened butter with garlic, parsley, thyme, salt, and pepper until smooth.

2. Place the mixture on plastic wrap, roll into a log, and chill until firm.

3. Slice into coins and place directly onto your hot steak just before serving.

The butter melts into the meat’s juices, creating a sauce right on the plate. Simple. Elegant. Perfect with those crispy fries we talked about in the steak frites blog.

Peppercorn Sauce: Bold, Creamy, Iconic

This is the sauce that makes you feel like you’re dining in a Parisian bistro—rich, velvety, and unapologetically indulgent.

You’ll need:

• 2 tablespoons black peppercorns, crushed

• 1 tablespoon butter

• 1 shallot, minced

• ½ cup brandy or cognac

• 1 cup heavy cream

• 1 teaspoon Dijon mustard

• Pinch of salt

Steps:

1. In a skillet, melt butter over medium heat and sauté shallots until soft.

2. Add the crushed peppercorns and toast for 30 seconds.

3. Carefully pour in the brandy (stand back—it may flame!) and let it reduce by half.

4. Stir in heavy cream and Dijon, then simmer until the sauce coats the back of a spoon.

5. Season lightly with salt.

This sauce clings beautifully to each bite of steak, giving you creaminess with a peppery punch. If garlic-herb butter is subtle elegance, peppercorn sauce is pure French drama.

Chimichurri: Fresh, Bright, and Alive

Now let’s head south, to Argentina, where steak practically demands a side of chimichurri. This sauce is the antidote to heavy flavors—it’s zesty, herby, and alive with freshness.

You’ll need:

• 1 cup fresh parsley, finely chopped

• ½ cup fresh cilantro, finely chopped

• 3 cloves garlic, minced

• ½ cup olive oil

• 2 tablespoons red wine vinegar

• 1 teaspoon dried oregano

• ½ teaspoon red pepper flakes

• Pinch of salt & black pepper

Steps:

1. Combine parsley, cilantro, and garlic in a bowl.

2. Stir in olive oil, vinegar, oregano, red pepper flakes, salt, and black pepper.

3. Let it sit for at least 15 minutes so the flavors meld.

Chimichurri brings brightness to the steak, cutting through richness with herbs and acidity. It’s especially brilliant with grilled meats and, yes, those golden fries from our steak frites recipe.

Bringing It All Together

Here’s the truth, Dear Chefs: every sauce tells a story. Garlic-herb butter whispers comfort. Peppercorn sauce belts out romance. Chimichurri dances with energy. Which one you choose depends on your mood, your company, and the kind of night you want to create.
