- 1 shallot
- 2 Fresno peppers
- 1 lemon, juiced
- 3 cloves of garlic
- 1 bunch parsley
- 1 tbsp Cusos Grass Seasoning

Best Chimichurri Recipe Instructions:
- Peel and seed the peppers. They are hot, so you may want to use gloves.
- Finely chop the poblano, fresnos, shallot, garlic, and parsley
- Mix with Cuso's Grass, Cuso’s Gravel, lemon juice, olive oil, and red wine vinegar
- Let the fresh chimichurri sit in the fridge for at least an hour to incorporate the flavors for the best results
- Enjoy with any meat of your choosing!
Tips for Making the Best Chimichurri
- I suggest chopping by hand. In a pinch, use a food processor, but it doesn’t create the traditional rustic texture of chimichurri.
- If your knife skills are lacking, pulse the fresh herbs individually in the food processor, then combine by hand with Cuso’s Seasonings.
- Remove the stems from your parsley for a smoother infusion.
- Don’t skimp on the resting period.
Pro Tip: Making the Cut
A little fastidious attention goes a long way when you are finely mincing herbs. Use a quality chef's knife for this purpose. One first-rate chef’s knife is the most practical and flexible tool in any cutlery drawer. It slices and dices, minces and chops. You can even use the flat side for crushing garlic cloves.

Secrets for Success With This Chimichurri Recipe
- Use high-quality ingredients like fresh flat-leaf parsley
- Mince the garlic very finely so people don’t get a harsh bite
- Give the mix time to set before you use it (overnight is great)
- For the best chimichurri recipe, stick with red wine vinegar and Extra-Virgin Olive Oil.
- Taste test before and after adding salt and pepper.
- If possible, let the chimichurri sauce rest overnight for maximum flavor.
From Chef Cuso: How to Craft Authentic Chimichurri
While knives are great, the way to make authentic chimichurri is by using a mortar and pestle. Mash all the herbs individually, then together. This will have a paste-like consistency. Add oil and vinegar, and you're all set!
Chimichurri Storage
If you place the chimichurri in an airtight container and refrigerate it, the optimum flavor lasts for about a week; however, it can still be good for an additional seven to eight days. You can also freeze it for up to three months.
Pro Tip: Storage Suggestion
A clever way to keep chimichurri in stock is by portioning it into ice cube trays. Pop them out when completely frozen and transfer them into a freezer-safe airtight storage bag. Take out as much as you need, when you need it.
