This recipe for Spaghetti and Shrimp with Spicy Pesto didn’t start out with pepper flakes. It never even occurred to me to pair pepper flakes with pesto. However, when I was sautéing the zucchini and shrimp I forgot I wasn’t making a butter sauce and sprinkled in the spice. One of those “aha moments” – spicy pesto is delicious!
Sauté zucchini, shrimp and crushed red pepper flakes in olive; add pesto and combine, stir in cooked spaghetti and a little pasta water, if need to thin the sauce. Garnish with cherry tomatoes. Click here for the Classic Pesto recipe.
