Why This Creamy Mustard Chicken Will Become Your New Favorite

We all have those trusty packages of chicken lingering in the freezer, a staple that can sometimes feel, well, a little uninspired. But with this creamy mustard chicken recipe, you can elevate your everyday chicken to a dish that feels utterly gourmet. Think of this sauce as the ultimate designer outfit for your chicken—it transforms it into something truly special and memorable.

The cream sauce for this dish is nothing short of extraordinary, bursting with deep, complex flavors. The magic begins with slowly caramelizing yellow onions and white button mushrooms, allowing their natural sweetness and umami to develop. This foundational step builds incredible depth. Then, the pan is deglazed with dry white wine, lifting all those flavorful browned bits from the bottom and integrating them into the sauce. The lush, velvety texture of the cream sauce comes from a clever combination of two types of mustard—Dijon for its sharp, tangy kick and whole-grain for its subtle texture and robust flavor—along with a fantastic dairy-free cream cheese or sour cream alternative. I genuinely adore this sauce so much that I often find myself dipping my side dishes, like crisp green beans, into it just to savor every last drop. It truly makes the entire meal feel indulgent and satisfying.

This recipe holds an extra special place in my heart because for many years, mustard was off-limits due to my son’s Eosinophilic Esophagitis (EOE). To finally reintroduce mustard into our family’s diet has been a joyful experience, and I will never take its vibrant flavor for granted again. This dish truly celebrates that culinary freedom.

And here’s the best part: while this creamy mustard chicken looks and, more importantly, tastes incredibly impressive, it can be on your table in under 30 minutes! This makes it an ideal solution for busy weeknights when you crave something comforting and delicious without spending hours in the kitchen.

Choosing the Best Chicken for Your Creamy Mustard Sauce

When it comes to selecting the chicken for this creamy mustard dish, you have flexibility to suit your preferences. I personally lean towards boneless, skinless chicken breasts for their lean texture and ease of preparation. However, the original Ina Garten recipe, which this dish is adapted from, traditionally calls for bone-in, skin-on chicken thighs. Chicken thighs offer a richer flavor and tend to stay juicier due to their higher fat content, which many people prefer. Feel free to use either chicken thighs or breasts depending on what you have on hand or what your family enjoys most.

Regardless of the cut you choose, the key to a perfectly cooked, tender, and safe meal is ensuring it reaches the correct internal temperature. Always use a meat thermometer inserted into the thickest part of the chicken. The chicken is fully cooked and safe to eat when it registers 165 degrees F (74 degrees C). For chicken breasts, butterflying them can help them cook more evenly and quickly, preventing the edges from drying out while the center finishes cooking. If using thighs, make sure to cook them slightly longer if they are bone-in to ensure thorough cooking near the bone.

Making This Creamy Mustard Chicken Perfectly Dairy-Free

One of the brilliant aspects of this recipe is how effortlessly it adapts to be completely dairy-free without sacrificing any of the rich, creamy texture or tangy flavor. Thankfully, the market now offers several excellent options for delicious dairy-free alternatives that truly shine in this entrée. My go-to for thickening and enriching the sauce is Tofutti sour cream. Made from soy, it provides a wonderful tang and smooth consistency that mimics traditional sour cream beautifully. In a pinch, I’ve also successfully used Tofutti’s dairy-free cream cheese, yielding very similar and equally delicious results.

If you need to avoid soy, there are still fantastic alternatives available. You could substitute a coconut-based dairy-free cream cheese, such as Daiya’s coconut-based cream cheese. Daiya’s products are known for their melt and stretch capabilities, making them excellent for creamy sauces. While a direct coconut-based sour cream can be harder to find, many coconut-based cream cheeses work perfectly as a substitute, especially when blended into a sauce. Another excellent option, if you need to avoid both soy and coconut, is Good Karma’s sour cream, which is typically made from flax milk. While I haven’t personally had the chance to try Good Karma’s sour cream in this specific recipe, it’s generally well-regarded as a reliable dairy-free and allergen-friendly option for sauces and dips.

For those who do not have dairy restrictions, feel free to use regular sour cream or cream cheese as specified in the original Ina Garten recipe. The adaptability of this dish ensures everyone can enjoy its incredible flavors, regardless of dietary needs.

Is This Creamy Mustard Chicken Naturally Gluten-Free?

Yes, you’ll be pleased to know that this creamy mustard chicken dish is inherently gluten-free! The primary ingredients—chicken, olive oil, onions, mushrooms, white wine, mustards, garlic, and parsley—do not naturally contain gluten. This makes it an excellent choice for individuals managing celiac disease or gluten sensitivities. However, for maximum safety and peace of mind, especially if you have severe allergies, it is always a good practice to thoroughly read through the ingredient labels of each product you use. Manufacturers’ recipes can occasionally change, or different brands might use varying processes that could introduce hidden gluten or cross-contamination. By double-checking labels, you ensure that every component of your meal remains perfectly safe and gluten-free.

What to Serve with This Gluten & Dairy Free Creamy Chicken

This Gluten & Dairy Free Creamy Mustard Chicken is incredibly versatile and pairs beautifully with a variety of side dishes. I personally love, love, LOVE serving it with crisp-tender green beans. The way they absorb the rich, tangy sauce is simply divine, creating a flavor profile that reminds me fondly of a deconstructed green bean casserole base. Steamed or roasted asparagus or broccoli would also make fantastic companions, offering earthy notes and a vibrant green contrast to the creamy chicken.

For the ultimate comfort food experience, spoon this delectable chicken over my dairy-free garlic parsley mashed potatoes. The creamy potatoes provide a perfect base to soak up every drop of that incredible sauce, making for a truly satisfying meal. Another favorite pairing in our household is my Instant Pot mushroom rice. The savory, earthy notes of the mushroom rice complement the chicken and sauce wonderfully, creating a hearty and flavorful dinner. A simple side salad with a light vinaigrette could also offer a refreshing balance to the richness of the dish.

Gluten & Dairy Free Creamy Mustard Chicken

Yield:
4 servings

Prep Time:
5 minutes

Cook Time:
20 minutes

Additional Time:
5 minutes

Total Time:
30 minutes

A rich cream sauce made of dairy free sour cream, white wine, mustard, caramelized onions and mushrooms makes for a divine comfort dish. An allergy friendly spin on an Ina Garten classic.

Ingredients

• 2 chicken breasts, butterflied
• 2 Tablespoons olive oil, separated
• 1 cup halved and thinly sliced yellow onions (approx 1 onion)
• 8 oz halved white button mushrooms
• 2 Tablespoons dry white wine
• 9 ounces dairy free cream cheese (see post above for options)
• 1 Tablespoon Dijon mustard
• 1 teaspoon whole-grain mustard
• 1 clove garlic (1/2 tsp minced)
• 1 tsp dried parsley 
• 1 and 1/2 tsp salt
• S&P to taste

Instructions

1. Butterfly and salt and pepper each side of the chicken breasts. Set aside.
2. Thinly slice the onions and halve the mushrooms.
3. Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the onions and mushrooms.
4. Cook over medium, until the onions are caramelized and the mushrooms are tender. Remove them from the pan and set aside.
5. Add the remaining tablespoon of oil and add your chicken in one layer. Cook until the side is light golden brown. Flip. Cook chicken through to a temperature of 165 degrees F.
6. Remove the chicken.
7. Deglaze the pan by adding the wine, stirring up any brown bits leftover from the cooking of the meat or vegetables. Lower the heat to medium low and add the, dairy free cream cheese, Dijon mustard, whole-grain mustard, garlic, parsley and 1 and 1/2 teaspoon of salt to the skillet and stir over medium heat until combined. Taste and adjust S&P to liking.
8. Return the chicken, the onions and mushrooms and add any juices the chicken has released to the skillet, and coat evenly. Serve hot.
9. Great with my mushroom rice & green beans.
10. **For a smoother/kid friendly sauce, as shown in the pictures see the directions in my notes.**

Notes

While I personally adore the rustic texture of the sautéed mushrooms and onions within the sauce, I understand that younger palates (or even some adults!) might prefer a smoother consistency. If you desire a silky, kid-friendly sauce, here’s a simple trick: after completing step 7, once the sauce has been fully heated through and combined, carefully transfer the cooked onions, mushrooms, and the entire sauce mixture to a blender. Blend until you achieve a perfectly smooth and creamy consistency. Then, simply pour this velvety sauce over your cooked chicken. This method results in the elegant, uniform sauce visible in the accompanying photographs, offering a wonderful alternative for those who prefer it. This recipe is lovingly adapted from the iconic Ina Garten’s Chicken Thighs in Creamy Mustard Sauce, ensuring a gourmet flavor profile with an allergy-friendly twist.
