Chicken Romesco is one of those recipes that sounds fancy but comes together in about 40 minutes with ingredients you can grab at any grocery store. It is tender, juicy baked chicken topped with a rich, smoky red pepper sauce that honestly tastes like something from a real sit-down restaurant. I threw this together on a Tuesday night, and my whole family wanted seconds before I even sat down.
The first time I made romesco sauce, I was a little skeptical. It looked too simple to be that good. But the moment it hit the food processor and that deep orange-red color came together, I knew something special was happening. This chicken romesco recipe has earned a permanent spot at our dinner table because it looks beautiful, the flavors punch way above the effort level, and the cleanup is practically nothing. The paprika rub on the chicken builds a gorgeous crust in the oven, and that velvety almond-pepper sauce ties everything together. Get ready for something delicious!

Ingredients for Chicken Romesco
I have made this chicken romesco recipe enough times now to know exactly what to reach for. I always use a jarred roasted red pepper here. They are already packed with smoky-sweet flavor and save a ton of time on a weeknight when you just need dinner on the table fast.
For the Chicken:
- 2 tsp ground paprika (I recommend smoked paprika if you have it, the depth of flavor is noticeable)
- 3/4 tsp kosher salt
- 1/4 tsp ground black pepper
- 1/4 tsp onion powder
- 1/4 tsp garlic powder
- 4 boneless, skinless chicken breasts (try to pick pieces that are similar in size so they cook evenly)
- 1 tbsp olive oil (my preference is extra virgin, it adds a little fruitiness that works well here)
For the Romesco Sauce:
- 12 oz roasted red peppers, drained (one standard 12 oz jar is exactly right)
- 1 tbsp tomato paste (in my experience, do not skip this, it is what gives the sauce real body and depth)
- 1 clove garlic, peeled
- 1 tbsp red wine vinegar
- 1/2 tsp ground paprika
- 1/4 cup toasted almonds (pro tip: toast raw almonds in a dry skillet for 3 to 4 minutes over medium heat until fragrant before adding them to the food processor)
Step-by-Step Instructions
In my experience, the biggest mistake people make with baked chicken breast is pulling it out too early or too late. A meat thermometer takes all the guessing out of it. Follow these steps and dinner will be on the table in 40 minutes flat.
Step 1: Preheat your oven to 400 degrees F. Give it a full 10 minutes to reach temperature before the chicken goes in.
Step 2: In a small bowl, mix together the paprika, kosher salt, black pepper, onion powder, and garlic powder until combined.
Step 3: Pat the chicken breasts dry with a paper towel first. This helps the spice rub actually stick instead of sliding off. Rub the mixture evenly over all four pieces, getting the sides and undersides too. Place on a rimmed baking sheet and drizzle with olive oil.
Step 4: Roast for 20 to 25 minutes, or until a meat thermometer inserted into the thickest part reads 165 degrees F. Thicker chicken breasts may need the full 25 minutes. Do not cut into the chicken to check doneness, that lets all the juices out.
Step 5: While the chicken bakes, add the drained roasted red peppers, tomato paste, garlic, red wine vinegar, paprika, and toasted almonds to a food processor. Pulse until smooth, or pulse just briefly if you want a chunkier texture. Taste and adjust with a small pinch of salt if needed.
Step 6: Pour the romesco sauce into a small saucepan and warm over low heat, stirring occasionally. If the sauce feels too thick, stir in 1 to 2 tablespoons of olive oil or water until it loosens to a pourable consistency.
Step 7: Once the chicken is done, move it to a cutting board and let it rest for 5 full minutes before serving. This keeps it juicy. Spoon the warm romesco sauce generously over the top, or spread it on the plate first and set the chicken on top for that restaurant-style look.
What to Serve with Chicken Romesco
The romesco sauce is smoky, slightly tangy, and nutty all at once, so the best sides are ones that either soak it up or cut through the richness with something fresh. Here are my favorite pairings:
Crusty Bread: A thick slice of sourdough or a warm baguette is the most natural pairing here. You will want something to scoop up every last drop of that sauce from the plate.

Easy Chicken Breast and Green Beans: If you want to build out a full veggie plate alongside this, simple oven-roasted green beans are a clean, crisp contrast that never compete with the bold romesco flavor.
Easy Balsamic Chicken and Veggies: The balsamic glaze and roasted vegetable combination makes a colorful, nutritious side that holds its own next to the richness of romesco sauce.
Garlic Roasted Vegetables: A sheet pan of roasted zucchini, asparagus, or broccoli tossed in garlic and olive oil is one of my go-to moves when I want a hands-off side that finishes right when the chicken does.
One Pan Mediterranean Chicken and Rice: If you want something more filling, fluffy rice is perfect for soaking up the romesco sauce. This one-pan version is a weeknight staple that pairs beautifully.
Creamy Garlic Sauce Potatoes: Creamy mashed or roasted potatoes underneath the chicken turn this into a truly comforting dinner. The garlic notes in both the potatoes and the chicken spice rub work really well together.
Easy Chicken Zucchini Bake: A light zucchini bake on the side keeps the meal fresh and adds a great texture contrast to the silky romesco sauce.
Storage and Serving Tips
Leftover chicken romesco keeps well in the refrigerator for up to 4 days. I recommend storing the sauce and chicken in separate airtight containers, which keeps the texture of both better than storing them together.
To reheat, warm the chicken in a 325 degree F oven for about 10 minutes, or slice it and warm it in a skillet over medium-low heat with a splash of water to keep it from drying out. Heat the romesco sauce separately in a small pot over low heat, adding a little water to loosen it if it has thickened in the fridge.
Pro tip: do not throw away leftover romesco sauce. It works incredibly well as a dip for raw vegetables, a spread on sandwiches, or spooned over scrambled eggs the next morning. I usually make a double batch of the sauce just so I have extra for the week.
Frequently Asked Questions
Can I use chicken thighs instead of chicken breasts?
Yes. Boneless skinless chicken thighs work great in this recipe. They tend to be a little more forgiving and stay juicy easily. They may need a few extra minutes in the oven, so check for an internal temperature of 165 degrees F before pulling them out.
Can I make the romesco sauce ahead of time?
Yes, and it actually gets better the next day. The sauce keeps in the refrigerator for up to 5 days. Make it the night before to save even more time on a busy weeknight.
Is this recipe gluten-free?
Yes, this chicken romesco recipe is naturally gluten-free as written. Just check the labels on your jarred roasted red peppers and tomato paste to make sure no starch or thickeners have been added.
