Chef tips
Lightly toast the walnuts in a dry skillet for 2 to 3 minutes to deepen the sauce’s flavor. If you prefer a looser romesco, add 1 to 2 tablespoons of water while blending.
Substitutions
You can use boneless chicken thighs instead of breast, adjusting the cooking time as needed. Walnuts can be replaced with almonds for a milder profile. Sherry vinegar may be swapped for red wine vinegar.
