Ingredients

1 tsp chili flakes (optional) – Adds a gentle heat kick
Salt and black pepper (to taste) – Always season generously for best flavor
2 tbsp extra virgin olive oil – Use good quality oil for richness
1 white onion (finely chopped) – Gives sweetness and depth
5 garlic cloves (minced) – Fresh garlic works much better than pre-minced
Splash of white wine – Helps deglaze and enhance flavor
200 ml chicken broth – Forms the base of the sauce
200 ml heavy cream – Creates that creamy, velvety texture
2 tbsp Dijon mustard – Smooth and balanced, blends perfectly in sauces

How to Make Spanish Chicken in Creamy Mustard Sauce Recipe?

This dish is all about building layers of flavor while keeping the process simple and enjoyable. I like to take it step by step to ensure the chicken stays juicy and the sauce turns out perfectly creamy. Follow these easy steps to bring this Spanish classic to life in your kitchen.

Prepare and Season the Chicken

Start by patting the chicken dry and placing it on a tray. Season both sides generously with salt, pepper, oregano, garlic powder, and smoked paprika. I like to rub the spices well so every bite is flavorful and balanced.

Brown the Chicken

Heat olive oil in a skillet over medium-high heat and place the chicken skin-side down. Cook until golden brown on both sides, which locks in flavor and adds texture. Don’t worry if it’s not fully cooked yet—it will finish later.

Sauté the Aromatics

Deglaze the pan with a splash of white wine and scrape up the browned bits for extra flavor. Add chopped onion and cook until soft and slightly golden. Then stir in garlic and cook briefly until fragrant.

Build the Creamy Mustard Sauce

Pour in the chicken broth, heavy cream, and Dijon mustard, then stir everything together. Let it gently simmer until the sauce becomes smooth and slightly thick. This is where the rich, tangy flavor really develops.

Simmer the Chicken

Return the chicken to the pan and coat it in the sauce. Let it simmer on low heat for about 25 minutes until fully cooked and tender. If needed, add a little broth to adjust the sauce consistency.

Garnish and Serve

Finish by sprinkling capers and a touch of paprika on top. I like to serve it hot so the sauce stays creamy and delicious. Pair it with bread or rice to soak up every bit of the sauce. Garlic Cod Bites with Creamy Lemon Herb Dip Recipe

Additional Tips for Making this Recipe Better

From my experience, these tips really elevate the dish:

I always sear the chicken properly—it adds incredible depth to the sauce
Don’t rush the onion cooking; caramelization brings natural sweetness
I prefer Dijon mustard because it blends smoothly without overpowering
Adding a little extra broth helps if the sauce thickens too much
Let the dish rest for a few minutes before serving—it improves flavor

This dish freezes well if cooled completely before storing. Keep it in a freezer-safe container for up to 2 months, but note the cream may slightly change texture.
