Spanish Chicken in Creamy Mustard Sauce Ingredients
• Get ready to make a dish that’s a hug in the form of food!
For the Chicken
- Chicken Thighs – The star of the dish; drumsticks or boneless breasts can also work for quicker cooking.
- Salt and Black Pepper – Essential for elevating all the flavors; adjust to your taste preference.
- Extra Virgin Olive Oil – This adds a wonderful distinct flavor; substitute with your favorite cooking oil if needed.
For the Sauce
- White Wine – It deglazes the pan and adds depth; chicken broth or water can be used as a replacement.
- Organic Low Sodium Chicken Broth – Provides a rich base for your sauce; homemade offers the best flavor, but store-bought works too.
- Heavy Cream – Creates a luxurious texture; half-and-half is a lighter option if you’re looking to cut some richness.
- Dijon Mustard – The central flavor; feel free to explore whole grain or yellow mustard for a different twist.
- Spanish Smoked Paprika – Brings a smoky aroma and vibrant color; regular paprika can be substituted in a pinch.
- Dried Oregano – Adds an herbaceous note; Italian seasoning is a good alternative if you’re low on oregano.
- Garlic Powder – Deepens the flavor profile; fresh minced garlic is a robust substitute.
- Chili Flakes – Add a touch of heat if you dare; omit for a milder dish.
- Turmeric Powder – Provides a lovely color; can be left out if you don’t have it on hand.
- Giant Capers – For garnish and a punch of flavor complexity; normal capers can easily step in.
For the Aromatics
- White Onion – Forms the base for flavor; shallots or yellow onion are perfectly fine substitutes.
- Garlic – Freshly minced adds that irresistible aroma; if fresh isn’t available, garlic powder works too.

Step‑by‑Step Instructions for Spanish Chicken in Creamy Mustard Sauce
Step 1: Prepare the Chicken
Begin by seasoning the chicken thighs with salt, black pepper, garlic powder, Spanish smoked paprika, dried oregano, and chili flakes if desired. Lay the seasoned thighs on a parchment-lined baking tray, allowing the flavors to meld while you heat your skillet.
Step 2: Brown the Chicken
In a large skillet, heat 2 tablespoons of extra virgin olive oil over medium-high heat. Once the oil shimmers, add the chicken thighs skin-side down and sauté for 5-7 minutes until golden brown. Flip the chicken and cook for another 5-7 minutes until both sides are crisp and browned. Remove the chicken and set it aside.
Step 3: Sauté the Aromatics
Using the same skillet, pour in 1/2 cup of white wine to deglaze, scraping any delicious browned bits off the bottom. Add 1 chopped white onion and sauté for about 3-4 minutes until softened and translucent. Then, stir in 3 minced garlic cloves and cook for an additional minute until fragrant.
Step 4: Build the Sauce
Lower the heat and mix in 1 cup of organic low sodium chicken broth, 1/2 cup of heavy cream, and 2 tablespoons of Dijon mustard. Sprinkle in a teaspoon of turmeric powder for color, and whisk until smooth. Allow the sauce to come to a gentle simmer, stirring occasionally, letting the flavors combine beautifully.
Step 5: Simmer the Chicken
Return the browned chicken thighs to the skillet, nestling them into the creamy sauce. Cover and simmer on low heat for 25 minutes, allowing the chicken to cook thoroughly and absorb the sauce’s rich flavors. Check occasionally, adjusting the sauce’s consistency with additional broth if needed.
Step 6: Serve and Garnish
Once the chicken is tender and the sauce has thickened, remove the skillet from heat. Garnish with giant capers and a pinch of smoked paprika for an extra pop of flavor. Serve the delicious Spanish Chicken in Creamy Mustard Sauce hot, alongside steamed rice or crusty bread to soak up that luxurious sauce.

Make Ahead Options
These Spanish Chicken in Creamy Mustard Sauce are a fantastic option for meal prep lovers! You can season the chicken thighs and refrigerate them for up to 24 hours before cooking, allowing the flavors to develop wonderfully. Additionally, the creamy mustard sauce can be prepared a day in advance; simply refrigerate it in an airtight container. When you’re ready to enjoy the dish, just sauté the chicken and then add it to the pre-made sauce, simmering until everything is heated through and the chicken is tender. This method ensures a delicious meal with minimal evening hassle, keeping your weeknights stress-free!

Spanish Chicken in Creamy Mustard Sauce Recipe FAQs
How do I pick the best chicken thighs for this recipe?
Absolutely! Look for chicken thighs that are plump, with a bright pink hue and no visible dark spots or discolorations. Opt for bone-in, skin-on thighs for the juiciest results, as the skin adds flavor and keeps the meat moist during cooking.
What is the best way to store leftovers?
Leftovers should be housed in an airtight container and kept in the refrigerator for up to 3 days. To maintain the best flavors and texture, allow your Spanish Chicken in Creamy Mustard Sauce to cool to room temperature before sealing. This prevents condensation buildup, which can affect the sauce’s consistency.
Can I freeze Spanish Chicken in Creamy Mustard Sauce?
Certainly! For longer storage, freeze your dish in a freezer-safe container for up to 3 months. To do this, let the chicken cool completely, then transfer it to the container. When sealing, ensure it’s airtight to avoid freezer burn. To thaw, place it in the fridge overnight, then reheat gently on the stove or microwave, adding a splash of broth if the sauce is too thick.
What if my sauce ends up too thick?
No worries! If your sauce thickens beyond your liking during cooking, simply add a splash of chicken broth or water to reach your preferred consistency. Stir gently until mixed in, and let it simmer for a couple of minutes to meld with the flavors. It’s a simple fix that keeps your dish creamy and delightful!
Are there any dietary considerations to be aware of?
Great question! This recipe contains gluten due to the Dijon mustard and possibly in the broth if you’re using store-bought options. Always check for gluten-free varieties to accommodate gluten sensitivities. Additionally, if you’re sensitive to dairy, low-fat substitutes like almond milk mixed with cornstarch can replace heavy cream, but the flavor and richness may vary.
Can I substitute the mustard in this recipe?
Absolutely! Dijon mustard is central to the flavor, but you can explore variations. Whole grain mustard adds texture, while yellow mustard offers a milder profile. If you prefer a more robust taste, feel free to mix in a touch of horseradish for a spicy kick, adjusting to your flavor preferences!
