Why You’ll Love This Skinny Pesto Sauce
Pesto is a beloved Italian sauce, but traditional recipes pack a calorie punch with loads of olive oil. If you’re looking for a lighter, healthier alternative without sacrificing flavor, this Skinny Pesto Sauce is your answer. By using a clever ingredient swap lemon juice we reduce the oil while keeping the sauce rich, vibrant, and utterly delicious.
Best of all, this recipe takes just 5 minutes to whip up in a food processor. Whether you’re pairing it with pasta, spreading it on sandwiches, or using it as a dip, this pesto will become a kitchen staple.

What Makes This Pesto “Skinny”?
Traditional pesto relies heavily on olive oil, which while healthy can quickly add up in calories. The secret to this lightened-up version is lemon juice, which:

You still get the creamy texture and bold taste of classic pesto, just with a smarter balance of ingredients.
