Wash parsley and cilantro very well. Dry them completely using a paper towel. Chop them finely on a cutting board. Fresh herbs are the base of this flavorful sauce.

Peel garlic cloves and mince them finely. You can also crush them using a garlic press. The garlic adds strong flavor, so make sure it is evenly chopped.

Take a mixing bowl and add chopped herbs and garlic. Stir gently so everything blends well. This step builds the fresh base of the chimichurri sauce.

Pour olive oil, red wine vinegar, and lemon juice into the bowl. Mix slowly so the herbs absorb the liquid. The sauce should start looking glossy and green.

Add salt, black pepper, chili flakes, and oregano. Stir well until everything is evenly mixed. Taste and adjust spice level based on your preference.

Let the chimichurri sit for at least 10 minutes. This helps flavors blend together and makes the sauce taste stronger and more balanced.

If you want smoother sauce, blend it slightly. If you prefer chunky texture, keep it as it is. Both versions taste equally delicious.

Serve fresh with grilled meat, chicken, or vegetables. You can also store it in a jar for later use.
