Romesco sauce originating from Tarragona in Catalonia (Spain), is normally prepared with toasted hazelnuts and almonds, but since I am for a sustainable kitchen that uses all resources without ever wasting anything, today I decided to replace them with pistachios (being Sicilian, they are never missing in my house) and walnuts to finish them before going on vacation. Romesco sauce is gluten and lactose-free and is ideal for those following a vegetarian or vegan diet.

Ingredients
- 1 red bell pepper
- 2 tomatoes, ripe, fresh
- 1 clove garlic
- 2 slices bread
- 1 hot chili pepper
- 1 teaspoon paprika
- 0.14 oz salt
- 2 tbsp extra virgin olive oil
- 2 tsp apple cider vinegar
- 1 pinch black pepper
- 0.11 cups walnuts, dry (toasted)
- 0.35 oz toasted pistachios
Tools
- Air fryer
- Chopper
Steps
I placed the tomatoes, garlic, and pepper in the air fryer (having washed everything beforehand).
With my air fryer at the highest temperature (392°F) they cooked in 20 minutes.
I put the pepper in a paper bag because this allowed me to peel the skin off much more easily. I peeled the tomatoes and peeled the garlic.
In the chopper, I put the tomatoes (seeded), peppers, garlic, bread, chili pepper, paprika, apple cider vinegar, pepper, oil, salt, walnuts, and pistachios.
I chopped everything until it became a homogeneous sauce.
Prepare some toasted bread and spread the Romesco sauce on it… then let me know.
FAQ
How can I use Romesco sauce?
It can be spread on bruschetta slices or used to dress pasta.
How long does Romesco sauce last?
Romesco sauce keeps well in the fridge for two days.
Can Romesco sauce be frozen?
I froze it to try, and I must say the taste didn’t change much, although I prefer it freshly made.
How can I preserve Romesco sauce over time?
It can be put in jars when still hot and sterilized in a pot (once the jars are inserted, we must cover them with a cloth and fill with cold water and bring to a boil for 30 minutes). Thanks to this method, it can be kept well in the pantry for even 3 months.
