Best Romesco Sauce Recipe

My thoughts

Romesco sauce is one of my favorites of all time. It’s so good and I haven’t found anything it hasn’t gone well with yet! I first learned about this recipe  as a young line cook working in the hotel business. I was lucky enough to make it for a party we had that night and I was so stoked I actually got to do something other than chop vegetables I jumped at the opportunity. After carefully producing this sauce to the specifications requested of me, I gave it one final taste before passing it on.  It was truly love at first taste! From then on, the Romesco sauce was a tool on my tool belt.

History of Romesco Sauce

Romesco sauce originates from Tarragona, Spain; located in the Catalonia region. More specifically, Romesco hails from a small neighborhood called El Serrallo.  This sauce was originally created by fisherman in the area, so its safe to say that its primary use if to accompany fish! The fishermen would mix together whatever they had laying around. These ingredients would include tomatoes, dried peppers, almonds, stale bread, oil, and vinegar.  This sauce was traditionally made with a mortar and pestle.

Over the years this sauce was tweaked by multiple people and cultures. The Romesco sauce adopted the use of red bell peppers. This sauce was served along side of many different vegetables and meats. One dish the region is known is grilled Calcots (Indigenous spring onion) with salsa Romesco.

What is Romesco Sauce

There is a lot of misconception of what a Romesco sauce actually is. Traditionally, an authentic Romesco sauce is made from tomatoes, garlic, and is thickened with stale bread or toasted nuts(usually almonds).  This sauce is flavored with some good olive oil, sherry vinegar, and other spices.

Another version of Romesco sauce is floating around out there as well. Actually, you will find this recipe more that you will find the REAL one. This pseudo Romesco sauce recipe calls for roasted red peppers rather than tomatoes, and the rest of the ingredients are usually the same.  There is nothing wrong with either recipe, one I just traditional and one is more of a “new age” recipe.

Luckily for you guys, I’m going to give you a recipe for both and you can decide which is better!

How Do You Make a Romesco Sauce?

Conjuring up a Romesco sauce is very simple. It doesn’t take much time and it packs huge flavor if done correctly.

To start off you need to pick your base. What I mean by that is, you need to choose whether you are going to use tomatoes or roasted red peppers. You could even do a hybrid that utilizes both tomatoes and peppers. Once you make that decision, the rest is a two step process.

First you need to char your vegetable(s). Char your peppers over a flame to achieve the best flavor, then place them in a bowl and cover with plastic wrap. This will make the skin easy to remove.  For tomatoes, You can either char the tomato over a flame or you can char in the oven at 500 F – 550 F.

Once your vegetables are roasted to your desired doneness, the harder the roast the better in my opinion. It is time to get your flavorings together. The typical flavorings include: Garlic, almonds or Stale bread, sherry vinegar, olive oil, and paprika. You may add other spices or ingredients if you like, its your sauce! I like a little heat so I add some reconstituted arbol chiles to mine!

Finally, you blend everything together! That is really all you got to do! Easy right? Ill get into more detail in a bit. Lets look at how to use this sauce!

Romesco Sauce Tricks and Tips

Consistency

Play around with consistency a bit until you find the right thickness for your needs. For example, if you are going to be using this sauce as a dip, then you are going to want it to be thick. On the other hand, if you are using it as a sauce the you are going to want your Romesco to be thinner so it fits the application better. It doesn’t take much skill just follow the recipes to get a thicker end result, and then thin it out if you deem necessary.

The consistency of Romesco sauce is affected by two main factors: they type of tomatoes used, and the amount of olive oil emulsified into it. Just remember you can always incorporate more oil but you cannot take it out so proceed with caution!

Acidity

Acid is what makes the Romesco sauce so delicious. It is important to obtain little bits of acid from different sources. You get acid from your olive oil (Slight), tomatoes ( moderate), and vinegar (high). A proper balance of all of these acids with leave you with a beautiful product.  You can even play around with the acidic ingredients, maybe incorporate some fresh citrus at the end to give your sauce a bright pop of flavor.

Tomatoes

Play around with the different types of tomatoes available to you and find out what sauce you like best. You can use any variety of tomato, you can also used canned tomatoes, or sundried tomatoes. There are many different possibilities.

Bread

Most Romesco sauce recipes call for a toasted white bread. Its very important you buy a nice country style white bread or French baguette. The reason being, is that you want to have a studier bread with a dense center. In the Romesco recipe, the bread is used as a thickening agent, the denser the bread the thicker the sauce. The typical sliced white bread you find in your local supermarket wont offer much to the consistency of your Romesco.

Paprika

There are a good bit of different varieties of paprika out there. I’m sure everyone has at least one type paprika in the cupboard right now. The most beneficial paprika for this particular sauce is the Spanish smoked paprika. Makes sense right? Spanish sauce, Spanish paprika.  This product is often referred to as “pimentón” or “pimentón de la Vera”. This spice has a little kick, so if your not into spicy then there are sweet varieties available.

Dried Peppers

If you end up choosing a recipe with dried peppers, it is important on how you reconstitute them. Sure you can soak them in hot water and reconstitute them that way. Using this method, you lose a lot of flavor in the water itself. I recommend frying the peppers in oil to rehydrate them. This keeps most of the flavor in the pepper and offers a slightly toasted flavor. This method takes a little finesse though, they can easily burn if the pan is too hot.

Another alternative to toasting the peppers, is placing them on a sheet tray and into a 350F oven for 6 minutes or until fragrant. This method is easier to pull of and has a very similar effect.

Toasting

To get the best flavor from your ingredients, you need to toast your bread and nuts (if using). You can toast both in the oven, which is what I recommend. Simply put the nuts and bread on trays and toast them in the oven and a low temperature(275-350F) . Make sure they are on separate trays, because they toast at different speeds. Keep an eye on them in the oven. You will know they are done when they are golden brown in color and fragrant.

For the bread, you can easily use a toaster or let it sit out uncovered for a few hours to dry out.

Store this sauce in an air tight container and keep in the fridge for up to 1 week!

Traditional Romesco Sauce

Romesco Sauce Recipe

Yield: 12 Servings

Prep Time: 5 Minutes

Cook Time: 45 Minutes

Ingredients

  • 4              Medium               Dried Nora Peppers or Ancho Chiles,seeds and stem removed
  • 3              Slices                     White Bread, toasted
  • 1              Head                     Garlic
  • 1              Lb                           Tomatoes, about  5-8 medium sized roma
  • ¾             Cup                        Almonds, toasted
  • 1 ¼         Cup                        Extra Virgin Olive Oil
  • ¼             Cup                        Sherry Vinegar
  • 1              Tbsp                      Pimenton

Instructions

  1. Preheat your oven to 450 F. White the oven is preheating, cut and X on the bottom of the tomatoes. The slits just need to break the skin, you don’t need to cut all the way through.
  2. Combine tomatoes and garlic in a mixing bowl and toss with 2 Tbsp of olive oil until just coated. Then lay out on a sheet tray. Once oven is heated, roast for 35 minutes.
  3. Once roasted, cool down the garlic and tomatoes. After they are cooled, peel off the skins from both vegetables. ( If you haven’t toasted your bread or almonds yet, now is the time to do so.)
  4. Once everything is toasted/ cooked, It is time to combine everything. You will need to do so in batches, depending on the size of your food processor or blender.
  5. For a smoother sauce, use a blender and blend all ingredients together. You may need to add more olive oil, vinegar, or water to get a thinner consistency. For a thicker chunky sauce, use a food processor using the pulse function. I recommend starting with the tomatoes and garlic, so you can get those chopped more fine. Slowly add the oil as the tomatoes and garlic are spinning. This way you can have the almonds as your chunky aspect.
  6. Once all is combined, season with salt and pepper and enjoy!!
