Yes, you can make romesco sauce without nuts! This traditional Spanish sauce is usually made with a mix of roasted red peppers, garlic, olive oil, paprika and almonds. Don't want to include them in your recipe if there is a nut allergy; simply leave them out and combine other ingredients. For example, you could substitute the almonds for toasted breadcrumbs or an alternative nut-free one like pumpkin seeds. You could also add herbs and spices like cumin, oregano and smoked paprika to add more flavor. To create an even creamier consistency, you could combine the ingredients with tomato paste or even cream cheese. Additionally, depending on how thick or thin of a texture you prefer, you can either purée it until smooth or keep it more chunky by blending for only a few seconds. Ultimately though, the best way to make romesco without nuts is to experiment and find the perfect combination that suits your taste buds!
