Lemon Herb Sauce

If you’re looking for a tasty and nutritious sauce to add flavor to your meals, this lemon herb sauce is a must try. It’s easy to make, loaded with flavor, and perfect for entertaining.

What to serve with this lemon herb sauce

This sauce is delicious drizzled on grilled or roasted vegetables like these roasted asparagus with balsamic vinegar. It would also be tasty with rice or these garlicky roasted potatoes. This sauce is perfect for dressing up simple dishes when you’re entertaining guests for dinner or lunch.

Main ingredients and substitutions

This sauce combines fresh parsley, mint, lemon, garlic, capers, and extra virgin olive oil. The herbs add freshness to this sauce, the lemon adds tang, and the capers add a briny saltiness that cuts through the richness of the extra virgin olive oil. 

I don’t add any extra salt to this lemon herb sauce because the capers are quite salty. If you choose to omit the capers then I recommend seasoning the sauce with salt to taste.

You can substitute olives or sun dried tomatoes instead of the capers if you prefer. Green olives are a particularly good alternative because they won’t detract from the vibrant green color of this sauce.

You can substitute other fresh herbs such as basil or cilantro if you prefer, but I think the combination of parsley and mint works best in this sauce.

If you don’t have a fresh lemon then you can substitute fresh lime. I don’t recommend substituting bottled lemon juice in this sauce.

I used extra virgin olive oil in this sauce but you can substitute any other relatively neutral oil. Avocado oil is a good alternative.

How to make it

This sauce is so simple to prepare. Start by adding the parsley, mint, lemon juice, olive oil, capers, garlic, and black pepper to a food processor or blender.
