This chimichurri is the kind of simple sauce that transforms weeknight dinners into something worth celebrating. I first learned to make this version on a humid summer evening when a friend from Buenos Aires brought a jar to a backyard barbecue. The fresh parsley and oregano, raw garlic, and a bright hit of red wine vinegar cut through rich grilled steak in a way that felt both rustic and elegant. It quickly became a staple in my kitchen — a spoonful added at the last minute livens up plain roasted vegetables, quick pan-seared fish, or a bowl of warm beans. What I love most about this preparation is how forgiving it is. The texture is loose and spoonable, with finely minced herbs suspended in olive oil rather than a thick paste. The garlic should be noticeable but not overpowering, the vinegar lending a gentle tang, while the crushed red pepper gives a faint, pleasant heat. When I make a batch, the house fills with bright herbal aroma and everyone knows dinner will be delicious. It keeps well for several days in the fridge and is one of those condiments that tastes even better after it rests.

Ingredients

• Fresh flat-leaf parsley (1 cup, packed): Choose bright green stalks without yellowing. Italian flat-leaf parsley has more flavor than curly parsley and holds up well in the oil. Rinse, shake dry, and pack loosely when measuring.
• Fresh oregano (1/2 cup) or dried (1 1/2 tablespoons): Fresh oregano gives a sweet, slightly minty edge. If using dried, use 1 1/2 tablespoons and let the sauce sit longer so the flavors hydrate.
• Garlic (4 medium cloves): Use firm, plump cloves. Mince finely to disperse the garlic flavor evenly; raw garlic mellows a bit as it rests in the oil.
• Red wine vinegar (2 tablespoons): For a classic tang; apple cider vinegar is a gentle substitute. The vinegar brightens the herbs and balances the oil.
• Crushed red pepper flakes (1 teaspoon): Adds gentle heat. Increase for more kick or omit for milder palates.
• Kosher salt (1/2 teaspoon) and black pepper (1/4 teaspoon): Season to taste — kosher salt disperses more evenly than table salt.
• Extra virgin olive oil (1/2 cup): Use a fruity, high-quality EVOO for the best mouthfeel and flavor; it serves as the flavor carrier so choose one you enjoy by the spoonful.

Instructions

Step 1 — Prepare the herbs and garlic: On a cutting board, stack the parsley and oregano, remove any thick stems, and chop the leaves into a fine mince. Mince the garlic separately until very fine. Visual cue: the herbs should look like tiny green confetti rather than large leaves — this helps the sauce cling to food. Step 2 — Combine aromatics and acid: In a mixing bowl, stir together the minced herbs and garlic with the red wine vinegar, crushed red pepper, kosher salt, and black pepper. The vinegar will draw aromatic oils from the herbs and mellow raw garlic slightly. Step 3 — Emulsify with olive oil: Slowly drizzle the extra virgin olive oil into the herbal mix while stirring with a spoon or wooden spatula. Aim for a loose emulsion — the texture should be saucy and pourable, not oily or separated. If it looks too oily, add a splash more vinegar or a teaspoon of water to bind. Step 4 — Rest and adjust seasoning: Let the mixture sit at room temperature for 15–30 minutes to allow flavors to meld. Taste and adjust with additional salt, pepper, or red pepper flakes. If you used dried oregano, give it at least 30 minutes. Step 5 — Serve or store: Spoon over grilled or roasted proteins, drizzle on vegetables, or serve as a condiment. Refrigerate leftovers in an airtight container for up to 5 days; freeze single portions in ice cube trays for up to 3 months.

Storage Tips

Store the sauce in an airtight glass jar or container; glass prevents flavor transfer and keeps the oil from picking up off-flavors. In the refrigerator, it will stay bright and fresh for about 4–5 days — the herbs will slowly darken but the flavor remains excellent. For longer storage, freeze in an ice-cube tray for single-serving portions; once frozen, transfer cubes to a labeled freezer bag for up to 3 months. To use frozen portions, thaw in the fridge for several hours or at room temperature for 20–30 minutes, then stir before serving.

Ingredient Substitutions

If you can’t find fresh oregano, substitute 1 1/2 tablespoons dried oregano but allow extra resting time for hydration. For a different herb profile, swap half the parsley for cilantro for a brighter, citrusy edge — this shifts the flavor toward Mexican-style herb sauce. Lemon juice can replace part of the vinegar (use 1 tablespoon lemon juice + 1 tablespoon red wine vinegar) for a fresher citrus note. For a nutty depth, stir in 1 tablespoon toasted sesame oil or 1 tablespoon finely chopped roasted walnuts at the end.

Serving Suggestions

Spoon generously over grilled flank steak or skirt steak for a classic pairing. It’s also brilliant on oven-roasted salmon, pan-seared scallops, or mixed into warm roasted potatoes. Use as a dressing for a simple grain bowl with quinoa and roasted vegetables, or mix half a cup into mayonnaise or Greek yogurt for a creamy chimichurri sauce for sandwiches and wraps. Garnish with a few extra chopped herbs and a light sprinkle of flaky salt when serving.

Cultural Background

Chimichurri originates from Argentina and Uruguay where it’s a classic accompaniment to grilled meats as part of asado traditions. The rustic, herb-forward sauce celebrates fresh, bold flavors and contrasts beautifully with charred meats. Regional variations exist: some Argentinians add parsley-heavy chimichurri with red pepper flakes, while others include cilantro, shallots, or even a splash of brandy. It’s a global favorite because of its simplicity and the way it brightens hearty foods.

Seasonal Adaptations

In summer, use the freshest parsley and oregano straight from the garden and increase the herbs for a brighter punch. In winter, mix in a tablespoon of preserved lemon or swap half the parsley for watercress or arugula to add peppery notes. On holidays, serve alongside roasted lamb or a herb-crusted roast chicken — consider adding roasted garlic for a deeper, mellow garlic flavor if you prefer something less sharp.

Meal Prep Tips

Make a double batch and keep a jar in the fridge for quick weeknight dinners. Use ice-cube tray freezing to portion single-serving amounts that are easy to thaw. If preparing ahead for a gathering, make the sauce a few hours before and bring to room temperature before serving so the oil is fluid and the flavors are lively. Label and date containers to track freshness.

End with a final note: this chimichurri has become a reliable, joyful staple in my kitchen. It’s the green spark that turns average meals into memorable ones — try it on something simple tonight and watch it bring new life to your plate.
