As the sun reaches its summer peak and farmers’ markets overflow with ruby-red bell peppers, it’s the perfect time to step away from greens and dive into something richer, smokier, and soulfully sweet: Roasted Red Pepper Pesto.
Also known in some regions as Pesto Rosso or Red Pesto, this vibrant sauce replaces leafy herbs with fire-roasted red bell peppers, creating a pesto that’s velvety, savory, slightly tangy, and just a little bit smoky. It’s a pesto with heat—not in spice, but in energy. It brings warmth to pasta, intensity to meats, and drama to even the simplest grilled bread.
In this article, we’re diving into Roasted Red Pepper Pesto, the bold, smoky cousin of the classic green variety. Packed with roasted red peppers, garlic, nuts, and cheese, this pesto brings rich flavor and bright color to everything from pasta to paninis. If you want pesto with attitude, this is it.
Origins – From Pesto alla Trapanese to Modern Variations
Roasted Red Pepper Pesto has roots in Sicily and Southern Italy, where tomatoes, almonds, and peppers form the base of many sauces. While Pesto alla Trapanese is a close cousin made with raw tomatoes and almonds, the roasted red pepper version emerged later as a hybrid of pesto, romesco, and Italian salsa rossa, merging bold Mediterranean flavors with pesto’s classic structure.
It’s a staple in modern Italian cooking—especially in Sicily, Calabria, and Puglia, where peppers are roasted on open flames and incorporated into everything from pastas to meat marinades.
