How To Make Chicken In Mustard Sauce – Pollo A La Mostaza

Ingredients

For the Chicken:

  • 6 bone-in chicken thighs (or use drumsticks or breasts if you prefer)
  • 1 tsp garlic powder
  • 1 tsp Spanish smoked paprika (pimentón)
  • 1 tsp Dried Oregano (organic)
  • 1 tsp chili flakes (optional: for some heat)
  • Salt and black pepper (to taste)
  • Extra Virgin Olive Oil
  • 1 white onion, finely chopped
  • 5 cloves garlic, minced
  • A Splash of white wine
  • 200 ml (1 cup) Organic Low Sodium Chicken Broth
  • 200 ml (1 cup) heavy cream
  • 2 heaped tablespoons Dijon Mustard (or wholegrain for extra texture)
  • 1 tsp Turmeric powder (optional for color)
  • 2 tablespoons of Giant Capers (or normal capers)

Equipment You’ll Need

A large pan of Spanish chicken in creamy mustard sauce

Step-by-Step Instructions

Step 1 – Prepare and Season the Chicken

  • Place the chicken thighs on a large tray lined with some parchment paper. 
  • Season generously with salt, pepper, dried oregano, garlic powder, and smoked paprika on both sides. 
  • We also add a little dried chili flakes for some extra heat and color (optional). 

Step 2 – Brown the Chicken

    • Add a splash of olive oil to a large skillet on medium-high heat. Once the oil is hot, add the chicken and cook for 5-7 minutes on each side, or until golden. 
    • Note: Don’t worry if the chicken isn’t cooked entirely, we’ll cook it more later in the sauce.

    Step 3 – Sauté the Aromatics

    • First, deglaze the pan by adding a splash of white wine (or water). Give the bottom of the pan a scrape to bring up the flavor. Don’t worry, the alcohol will burn off in around 2 minutes. 
    • Next, lower the heat to medium and add the diced onion and cook for 3–4 minutes until the onion is golden. 
    • Add the garlic and sauté for another minute or two until fragrant.

    Step 4 – Build the Sauce

    • Add the chicken broth, heavy cream, Dijon mustard, and turmeric powder. 
    • Bring to a gentle simmer and stir until the sauce is smooth and ingredients are combined. 

    Step 6: Simmer Chicken

    • Return the chicken thighs to the pan and simmer on low heat for 25 minutes. 
    • If the sauce gets too thick, add a splash more chicken broth, water, or milk

    Step 7: Serve and Garnish

    • Sprinkle with a few more giant capers and dust lightly with some smoked paprika. 
    • Serve hot. We suggest serving it with plenty of steamed rice or bread to soak up the delicious creamy mustard sauce.

      🍷 Serving Tips & Pairings

      • Drink pairing: A glass of dry Spanish white wine like Albariño or Verdejo complements the tang of the mustard and richness of the cream.

      • Side ideas: Serve with crusty bread to soak up the sauce, or try with patatas bravas or sautéed green beans, or some cucumber salad for a full Spanish-inspired meal.
      • Roasted potatoes or a dish of Poor Man’s Potatoes (patatas a lo pobre) also works great as a side with this recipe

      What Cut of Chicken Works Best

      For Pollo a la Mostaza (Spanish Chicken in Mustard Sauce), the best cuts of chicken are ones that stay juicy and flavorful during simmering. Note that searing bone-in, skin-on thighs until golden before simmering is key — it locks in flavor and gives the mustard-cream sauce extra depth.

       

      1. Bone-in, Skin-on Chicken Thighs (⭐ Best Overall)

      • Why they’re great: Super juicy, rich in flavor, and hold up well to slow simmering.
      • Bonus: The skin adds depth and richness when browned.
      • Cooks in: ~25–30 minutes, simmered.

      2. Chicken Drumsticks

      • Why they’re great: Similar to thighs in texture and flavor, great for rustic presentations.
      • Bonus: Kids love them!
      • Cooks in: ~25–30 minutes.

      3. Boneless, Skinless Chicken Thighs

      • Why they’re good: Tender and flavorful like bone-in, but quicker to cook and easier to eat.
      • Bonus: No bones, faster prep.
      • Cooks in: ~20–25 minutes.

      Best Mustard to use for Pollo a la Mostaza

      In Pollo a la Mostaza (Chicken with Mustard Sauce), the type of mustard used can vary depending on the region or the cook, but it’s typically not a traditional Spanish mustard—since Spain doesn’t have a long history of mustard-based cuisine.

      However, in modern Spanish kitchens, Dijon mustard is actually the most commonly used type for this dish.

      Why Dijon?

      • Its smooth texture and balanced sharpness blend well in creamy sauces.
      • It integrates seamlessly with ingredients like cream, white wine, garlic, and herbs, which are often found in Pollo a la Mostaza recipes.

      Other Variations:

      • Some home cooks might use whole grain mustard (mostaza a la antigua) for texture and a milder flavor.
      • Occasionally, yellow mustard (American-style) may be used in more casual or simplified versions, but this is rare and less typical in Spanish or European contexts.

      Giant Capers – Alcaparones

      Giant capers, also known as caper berries, make a great addition to this salad as they offer a sweet, slightly bitter tang with just a little crunch. Giant capers are widely used in salads in Spain and are readily available in most supermarkets. 

      Outside of Spain, any decent Mediterranean food store should stock them, and they are also available online. If you can’t source giant capers, normal capers will also work well for this recipe.
