These Sweet Potato Fries with Pesto Aioli have a spicy kick. The sweet potatoes are seasoned with a blend of chili powder and paprika, and the creaminess of the pesto and mayonnaise sauce provides a one-two punch of flavor to mellow it out. It’s also the most obvious of flavor combinations for this blog, and it’s one I’ve made for years.
The oven-baked fries are a great appetizer or party snack on their own, or you can pair them with your favorite burger or sandwich to complete a weeknight meal. The fries get nice and crispy on the outside and carry that crunch for scooping up plenty of Pesto Aioli.
Of course you could make these in the air fryer, if that’s your thing. But there’s just something about lining up the individual fries in perfect order on large baking sheets that’s so satisfying.
How to Make Mayonnaise and Pesto Sauce
The pesto aioli for these sweet potato fries is a 5-ingredient wonder sauce that’s great for spreading on beet and bean burgers, serving with fresh veggies or a dipping sauce for whatever dish needs a little lift.
- ¼ cup prepared pesto
- ¾ cup mayonnaise
- ½ lemon, juiced
- 2 cloves garlic, minced
- 1 teaspoon whole grain mustard
Simply add all 5 ingredients to a medium bowl and whisk until combined. Make it in advance and store in an air-tight container in the refrigerator for up to 5 days.
