Wash cilantro leaves properly and pat them dry. Cut jalapeños into small pieces and remove seeds if you want less heat. Peel garlic cloves and keep everything ready.

Fresh ingredients are very important for bright color and strong flavor in this sauce.

Put cilantro, jalapeños, and garlic into a blender. Add mayonnaise and Greek yogurt next.

These create a creamy base. Make sure everything is evenly placed for smooth blending. This step builds the strong green color and rich texture of the sauce.

Start blending at low speed and slowly increase. Add olive oil and lime juice while blending. The mixture will turn bright green and creamy.

If it feels too thick, add a little water. Blend until you get a smooth and silky sauce.

Taste the sauce carefully after blending. Add salt and black pepper for seasoning. If you want more spice, add extra jalapeño. For more freshness, add a bit more lime juice.

Mix again briefly to combine all flavors evenly and nicely.

Check the texture of your sauce. It should be creamy but pourable. If it is too thick, add small amounts of water. Blend again for a few seconds. Your Aji Verde Peruvian Green Sauce is now ready to serve with your favorite dishes.
