Romesco sauce is a classic Spanish sauce made with almonds and roasted red peppers. Serve it on top of buttery sablefish for a delicious and healthy meal!
When the weather starts to warm up, I like preparing dishes that don’t require a lot of cooking time over a hot stove. Romesco sauce is one of my favorite no-cook sauces to make and is a staple in my household.
What is sablefish?
I use wild Alaskan sablefish (black cod) in this dish. I first learned about sablefish many years ago when I had the most delicious melt-in-your-mouth miso glazed black cod at the legendary restaurant Nobu in New York City.
Sablefish is a white fish with a delicate, velvety texture and sweet, buttery flavor. It has a nice richness that makes it an excellent choice for dinner.
Sablefish is also a lean fish that’s high in omega-3 fatty acids. It has about the same amount of omega-3s as salmon. It's rich in nutrients like vitamin B12 and is low in mercury.
I use wild Alaska sablefish in this recipe. So in addition to being healthy, it's also a sustainable fish choice.
If you're trying it for the first time, it may become your new favorite fish! If you can’t find sablefish at your grocery store, you can substitute any type of fish that you like such as halibut, grouper or cod.
What is Romesco sauce?
Romesco sauce is a classic Spanish sauce made by pureeing almonds, roasted red peppers, tomatoes, vinegar and seasonings.
It's very easy to make and requires no cooking. Simply puree all of the ingredients together in a blender and you’re done!
It's also very nutritious. It has almonds and olive oil, which are packed with heart healthy unsaturated fats. Nuts are also a great source of protein and fiber and contain several other nutrients that have beneficial effects on heart health including Vitamin E, plant sterols, selenium and L-arginine.
The sauce gets a nice smoky flavor from roasted red peppers and Spanish smoked paprika. Spanish sherry vinegar adds brightness and acidity to the sauce and a small amount of bread thickens it.
Ingredients
- Sablefish (black cod) filets
- Roasted red peppers
- Tomato
- Almonds
- Garlic
- Spanish sherry vinegar
- Extra virgin olive oil
- Smoked Spanish paprika
- Bread
Instructions
Another reason I love sablefish is that it's so easy to cook! Simply heat some oil in a hot skillet and cook it about 3-4 minutes on each side.
The Romesco sauce is also very easy to make. Simply place all the ingredients in the a food processor or blender and blend away. No cooking at all!
You can serve Romesco sauce on top of pretty much anything! I love it on seared sablefish but it's also delicious on grilled steak, chicken or vegetables.
You may want to double the recipe and keep the leftovers in the fridge. I promise it won’t go to waste!
What to serve with sablefish
I also serve the delicious sablefish with a dollop of Romesco sauce on top and extra sauce on the side. You can serve it with quinoa or brown rice and a salad or vegetable to round out the meal.
Try this sablefish with my Quinoa with Roasted Vegetables or Quinoa Salad with Spinach and Strawberries. You can also serve it with Miso Roasted Brussels Sprouts, Perfect Air Fryer Asparagus or Miso Roasted Rainbow Carrots. Round out your meal with my Tuscan Kale and Apple Salad or Roasted Butternut Squash Salad.

Love the Sienne Maya recipe!
The Romesco sauce seems to be easy enough to prepare. I would like to try it with salmon, since Alaskan black cod is not always available.
Thank you for this simple recipe.
