Why I love this creamy mustard chicken
Chicken is a pantry staple, but it can feel ordinary unless you dress it up. This recipe does exactly that: the caramelized onions and mushrooms lend deep, savory flavor, the white wine deglazes the pan and lifts the fond, and the mustard plus dairy-free cream create a lush, velvety sauce. The result is rich and satisfying without dairy, and the sauce is good enough to dip vegetables into—don’t waste a drop.
On a personal note, mustard was off-limits for my family for several years because of a child’s food sensitivities, so being able to enjoy mustard again feels like a small culinary celebration. Despite tasting and looking impressive, the whole dish comes together in under 30 minutes, making it perfect for weeknights or a cozy date night at home.
What kind of chicken can I use for this creamy mustard chicken?
You can use either chicken breasts or thighs. The original recipe uses thighs, but breasts work equally well. The important point is to cook the meat until the internal temperature reaches 165°F (74°C) at the thickest part for safe, juicy results.
How do you make this creamy mustard chicken dairy free?
There are several reliable dairy-free options. I often use a soy-based sour cream alternative to add creaminess and body to the sauce. Dairy-free cream cheese works well too. If soy is a concern, coconut-based cream cheese can be a good substitute. Another alternative is a cultured, plant-based sour cream made from legumes or oats, depending on availability and dietary needs. If you can tolerate dairy, regular sour cream or cream cheese can be used without further modification.
Is this creamy mustard chicken gluten free?
Yes. The dish is naturally gluten-free when made with standard ingredients listed here. Always double-check product labels to ensure a particular brand hasn’t changed formulations or introduced cross-contamination risks.
What is good to serve with this Gluten & Dairy Free Creamy Chicken?
Green beans are a favorite pairing; the sauce tastes similar to the base of a green bean casserole, making them a natural match. Steamed asparagus or roasted broccoli also work well. Serve the chicken over dairy-free mashed potatoes for a classic combination, or try mushroom rice for an earthy complement that echoes the sauce’s flavors.
Do I have more gluten & dairy free chicken dinners?
Yes—this recipe comes from a site focused on allergy-friendly cooking. With many recipes that avoid common allergens, you’ll find a variety of weeknight and special-occasion chicken dishes designed to be safe for households managing food sensitivities. Examples include dairy-free creamy Tuscan chicken, allergy-friendly fried chicken, lemon grilled chicken, and several one-pot or instant pot options that are both quick and flavorful.

A rich, dairy-free cream sauce combining mustard, white wine, caramelized onions and mushrooms creates a comforting dinner with bold flavor and elegant presentation.
Ingredients
- 2 chicken breasts, butterflied
- 2 tablespoons olive oil, divided
- 1 cup thinly sliced yellow onion (about 1 onion)
- 8 oz white button mushrooms, halved
- 2 tablespoons dry white wine
- 9 ounces dairy-free cream cheese or sour cream alternative
- 1 tablespoon Dijon mustard
- 1 teaspoon whole-grain mustard
- 1 clove garlic, minced (about 1/2 tsp)
- 1 tsp dried parsley
- 1 1/2 tsp salt, plus additional salt and pepper to taste
Instructions
- Butterfly the chicken breasts, season both sides with salt and pepper, and set aside.
- Thinly slice the onion and halve the mushrooms.
- Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the onions and mushrooms.
- Cook, stirring occasionally, until the onions are caramelized and the mushrooms are tender. Remove them from the pan and set aside.
- Add the remaining tablespoon of oil to the skillet and arrange the chicken in a single layer. Sear until golden on one side, flip, and continue cooking until the internal temperature reaches 165°F (74°C).
- Remove the cooked chicken from the pan and set aside.
- Deglaze the skillet with the white wine, scraping up any browned bits. Reduce the heat to medium-low, then stir in the dairy-free cream cheese (or sour cream alternative), Dijon and whole-grain mustards, minced garlic, dried parsley, and 1 1/2 teaspoons salt. Stir until the sauce is smooth and warm. Adjust salt and pepper to taste.
- Return the chicken to the skillet along with the caramelized onions and mushrooms and any accumulated juices. Spoon the sauce over the chicken to coat evenly and serve hot.
- For a smoother, kid-friendly sauce, blend the onions, mushrooms, and sauce in a blender until creamy, then pour over the chicken.
Notes
Some family members prefer a uniform, creamy sauce without visible pieces of onion or mushroom. If you prefer a smooth sauce, simply blend the cooked onions, mushrooms, and sauce until smooth before returning it to the skillet. This also makes the sauce more appealing to picky eaters while keeping all the same flavors.
