Directions

Roast the Peppers: Preheat the oven to 400°F (200°C). Roast the red peppers on a baking sheet for 20-25 minutes, turning occasionally, until charred on all sides.

-
Add Olive Oil: While the processor is running, drizzle in the olive oil and continue blending until the pesto reaches your desired consistency.
-
Season: Add salt, pepper, and red pepper flakes (if using). Blend again briefly to combine.
-
Serve or Store: Use the pesto immediately as a sauce for pasta, a spread for sandwiches, or a dip. If you’re not using it right away, store it in an airtight container in the refrigerator for up to 5 days.
