Chicken Breasts with Mustard Mushrooms

Why You’ll Love This Recipe

I absolutely love making Chicken Breasts with Mustard Mushrooms because it’s full of flavor, quick to prepare, and perfect for both casual dinners and special occasions. The chicken is juicy and tender, while the creamy mustard mushroom sauce adds a rich, tangy depth that takes the dish to another level. The mushrooms soak up the savory sauce beautifully, and the Dijon mustard brings just the right amount of sharpness to balance the creaminess. It’s a comforting and elegant dish that pairs wonderfully with mashed potatoes, rice, or crusty bread.

Ingredients

• 2 large chicken breasts, boneless and skinless

• 1 tablespoon olive oil

• Salt and black pepper to taste

• 1 tablespoon butter

• 1 small onion or shallot, finely chopped

• 2 garlic cloves, minced

• 2 cups mushrooms, sliced (button, cremini, or a mix)

• 1/2 cup chicken broth

• 1/2 cup heavy cream (or crème fraîche)

• 1 tablespoon Dijon mustard

• 1 teaspoon whole grain mustard (optional)

• 1 tablespoon chopped parsley (for garnish)

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Prepare the Chicken:

1. Season the Chicken: Season the chicken breasts on both sides with salt and pepper.

2. Sear the Chicken: Heat the olive oil in a large skillet over medium-high heat. Add the chicken breasts and sear for about 5–6 minutes per side, or until golden brown and cooked through (internal temperature should reach 165°F or 75°C). Remove the chicken from the pan and set aside.

Prepare the Mustard Mushroom Sauce:

3. Sauté the Aromatics: In the same skillet, reduce the heat to medium. Add the butter and sauté the chopped onion (or shallot) for 2–3 minutes until softened.

4. Add Garlic and Mushrooms: Add the minced garlic and sliced mushrooms. Cook for about 5–6 minutes until the mushrooms are golden brown and have released their moisture.

5. Deglaze with Broth: Pour in the chicken broth and stir, scraping up any browned bits from the bottom of the pan. Let it simmer for 2 minutes.

6. Add Cream and Mustard: Stir in the heavy cream, Dijon mustard, and whole grain mustard (if using). Let the sauce simmer gently for another 3–4 minutes until slightly thickened.

7. Return the Chicken: Place the chicken breasts back into the pan, spoon some sauce over the top, and let everything cook together for another 2–3 minutes so the flavors can meld.

Serve:

8. Garnish and Serve: Sprinkle with chopped parsley and serve hot, with a side of mashed potatoes, rice, or fresh vegetables.

Servings and Timing

This recipe serves 2–3 people. Prep time is about 10 minutes, and cook time is around 25 minutes, making the total time approximately 35 minutes.

Variations

If I want to lighten the dish, I sometimes use half-and-half or milk instead of heavy cream. You can also use chicken thighs instead of breasts for a juicier cut. To add more flavor, I sometimes stir in a splash of white wine or a teaspoon of lemon juice for brightness.

Storage/Reheating

Leftovers can be stored in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over low heat or in the microwave, adding a splash of broth or cream if the sauce has thickened too much.

FAQs

Can I use different types of mustard?

Yes! Dijon is classic, but whole grain mustard adds great texture. You can also use spicy mustard or honey mustard for a different twist.

Can I make this dish ahead of time?

Yes, you can make it ahead and reheat it gently. Just keep the chicken and sauce stored together to maintain the flavor.

What mushrooms work best for this recipe?

Cremini, button, or even wild mushrooms like shiitake or oyster work great. A mix adds more depth of flavor.

Can I freeze this dish?

I don’t recommend freezing due to the cream-based sauce, which can separate when thawed. It’s best enjoyed fresh or refrigerated.

What can I serve with this dish?

It pairs perfectly with mashed potatoes, pasta, rice, or crusty bread to soak up the sauce. A light green salad or steamed veggies also make great sides.

Conclusion

Chicken Breasts with Mustard Mushrooms is a flavorful, creamy, and comforting dish that’s quick enough for weeknights yet elegant enough for guests. The combination of tender chicken, earthy mushrooms, and creamy mustard sauce creates a dish that’s rich and satisfying without being heavy. Once you try it, I’m sure it’ll become one of your favorite go-to recipes!
