Quick Chicken Breast with Spanish Romesco Sauce

Ingredients

For the Sauce

  • ½ cup whole almonds
  • 3 garlic cloves, peeled
  • ½ of a 16-ounce jar of roasted red bell peppers, drained, seeded, roughly chopped
  • 2 medium tomatoes, cored and quartered
  • ¼ cup finely chopped onion
  • 3 tablespoons extra-virgin olive oil
  • 1½ teaspoons paprika, regular or smoked
  • 1 teaspoon sherry vinegar or red wine vinegar
  • ¼ teaspoon sea salt
  • ¼ teaspoon ground black pepper

For the chicken

  • 4 boneless, skinless chicken breasts (about 1½ pounds)
  • ¼ teaspoon sea salt
  • ¼ teaspoon ground black pepper
  • ¼ teaspoon granulated garlic
  • 1 tablespoon extra-virgin olive oil
  • ½ cup low-sodium chicken broth

Method

Step 1

Prepare a food processor fitted with the steel blade. With the machine running, drop the almonds and garlic cloves through the feed tube and process until finely ground, about 20–30 seconds. Add the bell peppers, tomatoes, onion, olive oil, paprika, vinegar, salt, and pepper. Process until a fairly smooth sauce forms, about 1–2 minutes.

Step 2

Season the chicken with salt, pepper, and garlic. Heat the oil in a large stainless steel or cast iron pan over medium heat. When the pan and oil are hot (but not smoking), add the chicken breasts smooth side down. Cook until golden on the first side, about 5 minutes.

Step 3

Turn the chicken over, add the broth to the pan, cover pan with a tight- fitting lid and turn the heat to low. Allow the chicken to cook until it measures 165°F, about 7 to 8 minutes longer. Allow chicken to rest for a few minutes, then slice across grain. Serve with 1/3 cup of the Romesco sauce per person. Store any leftover chicken and sauce separately in glass containers with tight-fitting lids. The chicken will keep for up to 3 days, and the sauce for 4 to 5 days.

At Mark’s Kitchen, we know that food is medicine, but even the healthiest diets can be missing key nutrients essential for longevity. One of those is C15:0, an essential fatty acid scientifically proven to support liver, red blood cell, cholesterol and gut microbiome health—yet most modern diets don’t provide nearly enough of it. That’s where fatty15 comes in.

Fatty15 is the world’s first and only pure, patented form of C15:0. Unlike omega-3s, which can break down over time, this unique fatty acid works at the cellular level to strengthen cell membranes, enhance mitochondrial function, and calm inflammatory responses—key factors in slowing the aging process. It’s also backed by rigorous science, with more than 100 peer-reviewed studies supporting its role in improving sleep, energy levels, mood, and long-term health.

I take fatty15 every day because I’ve seen firsthand how powerful it is. It’s a simple, science-backed addition to my routine that helps me feel my best and stay sharp. If you’re looking for an easy way to support your body from the inside out, I highly recommend giving it a try. Visit fatty15 and use code HYMAN for 15% off your 90-day Starter Kit.
