Garlic Scape Chimichurri Sauce

My neighbor's garden overflowed with garlic scapes last summer, and she showed up at my door with an entire basket of those curly green stems. I'd never cooked with them before and honestly had no idea what to do, so she taught me how to make this chimichurri right there in my kitchen while we caught up about life.

Last July, we hosted an impromptu backyard grill night and I made a double batch of this sauce. My brother usually skips anything green and herbaceous, but he kept going back for more and ended up asking for the jar to take home.

Ingredients

• Garlic scapes: These are the flowering stems from garlic plants and they have a milder, sweeter garlic flavor than cloves
• Fresh parsley and cilantro or oregano: The combination creates layers of herbaceous brightness that cutting fresh herbs is worth every minute
• Shallot: Provides a subtle sweetness that regular onions are too sharp to deliver
• Red chili or pepper flakes: Just enough heat to wake up your palate without overwhelming the fresh flavors
• Extra-virgin olive oil: Use the good stuff here since its the main fat carrying all those vibrant flavors
• Red wine vinegar: Adds the essential tang that cuts through rich grilled meats
• Fresh lemon juice: Brightens everything and helps preserve that gorgeous green color
• Salt and black pepper: Simple seasonings that let the herbs shine while grounding the sauce

Instructions

Prep your aromatics:

Roughly chop the garlic scapes, parsley, cilantro or oregano, shallot, and chili so they fit easily in your food processor

Create the herb base:

Pulse everything until finely chopped but not completely smooth, you want some texture remaining

Add the liquids:

Pour in the olive oil, vinegar, lemon juice, salt, and pepper, then pulse until combined into a thick sauce

Adjust the consistency:

Add a tablespoon of water if the sauce feels too thick, then taste and tweak the seasoning or acid as needed

Save

Something magical happens when this sauce hits hot grilled food, the herbs release their oils and the whole dish comes alive with fragrance. I made this for a summer potluck and watched three different people ask for the recipe within minutes of taking their first bite.

Making Ahead

This sauce actually improves after sitting in the refrigerator for a day as the garlic mellows and the herbs infuse the oil more deeply. I often make a double batch on Sunday and keep it in a glass jar for quick weeknight meals that feel special.

Serving Suggestions

Spoon this generously over grilled steak, chicken thighs, or white fish during the last minute of cooking so the sauce warms through slightly. It also transforms roasted vegetables, scrambled eggs, and even makes an incredible sandwich spread.

Variations To Try

Substitute half the olive oil with melted ghee for a richer, nuttier flavor profile that stands up to hearty grilled meats. You can also add a handful of fresh mint leaves for a brighter, more refreshing version perfect for spring vegetables.

• Try swapping red wine vinegar for apple cider vinegar for a fruitier tang
• Add a teaspoon of ground cumin for a smoky depth that pairs beautifully with lamb
• Mix in a tablespoon of Dijon mustard for extra creaminess and sharpness

Save

Every time I serve this chimichurri, someone asks why my grilling tastes more vibrant and restaurant-quality than theirs do. The secret is always this sauce.

Recipe FAQs

→ What are garlic scapes?

Garlic scapes are the curly, green flower stalks that emerge from hardneck garlic plants in early summer. They have a milder garlic flavor than cloves and a texture similar to asparagus or green beans. They're typically available at farmers markets from late spring through mid-summer.

→ Can I freeze this sauce?

While you can freeze garlic scape chimichurri, the texture and vibrant color may change slightly upon thawing. For best results, freeze in ice cube trays, then transfer to a freezer bag. Use within 2-3 months. Thaw in the refrigerator overnight before serving.

→ What dishes pair best with this sauce?

This chimichurri shines on grilled steak, flank steak, or skirt steak. It's also excellent on grilled chicken, pork chops, salmon, or shrimp. Vegetarian options include roasted potatoes, grilled portobello mushrooms, cauliflower steaks, or drizzled over grilled tofu and eggplant.

→ How long does the sauce stay fresh?

The sauce stays fresh for up to 3 days when stored in an airtight container in the refrigerator. The herbs may oxidize slightly over time, but the flavor remains robust. For the brightest flavor and most vibrant green color, use within 24-48 hours.

→ Can I make this without a food processor?

Yes, you can finely chop all ingredients by hand, then whisk together with the oil and vinegar. The texture will be chunkier rather than smooth, but the flavor remains equally delicious. A mortar and pestle also works well for creating a more rustic, traditional texture.

→ What can I substitute for garlic scapes?

If garlic scapes aren't available, substitute with 4-5 cloves of fresh garlic plus 1 cup of green onions or scallions. The flavor will be more pungent than the mild garlic scapes, so you may want to reduce the garlic slightly to suit your taste preference.
