Step 1: Finely chop the fresh flat-leaf parsley. You can do this by hand for a rustic texture or pulse briefly in a food processor, being careful not to over-process into a paste.
Step 2: Mince the garlic cloves very finely. Again, by hand or using a garlic press for a smoother consistency.
Step 3: In a medium bowl, combine the chopped parsley, minced garlic, dried oregano, red pepper flakes, salt, and black pepper.
Step 4: Pour in the red wine vinegar and extra virgin olive oil. Mix well with a spoon until all ingredients are thoroughly combined. The mixture should be bright green and fragrant.
Step 5: Taste the Chimichurri Sauce Recipe and adjust seasonings as needed. You might want a little more salt, pepper, or red pepper flakes depending on your preference. The flavors will meld and intensify as it sits.
Step 6: For best results, cover the bowl and let the Chimichurri Sauce Recipe sit at room temperature for at least 15-30 minutes before serving. This allows the flavors to meld beautifully. You can also refrigerate it for up to 1-2 hours before serving, but bring it back to room temperature for optimal flavor.
Step 7: Serve your fresh Chimichurri Sauce Recipe over grilled meats, chicken, fish, or vegetables. Store any leftovers in an airtight container in the refrigerator for up to 5-7 days.
