Step 1: Prepare the Herbs

Finely chop the parsley and cilantro (if using). If you prefer a smoother texture, you can pulse them in a food processor.

Step 2: Mince the Garlic

Peel and finely mince the garlic cloves. If you love a strong garlic flavor, you can use extra cloves.

Step 3: Combine the Ingredients

In a mixing bowl, combine the chopped parsley, cilantro, garlic, and shallots. Add dried oregano, red pepper flakes, salt, and black pepper.

Step 4: Add Liquids

Pour in the red wine vinegar and lemon juice (if using). Slowly drizzle in the olive oil while stirring continuously to create a well-emulsified sauce.

Step 5: Let It Rest

Allow the chimichurri sauce to sit for at least 15–30 minutes before using. This helps the flavors meld together, resulting in a more delicious sauce.
