The mustard selection is critical for authentic flavor. Maille or Grey Poupon for the Dijon, and a coarse whole grain mustard with visible seeds adds the proper texture. Heavy cream must be full-fat—lower percentages won’t achieve that luxurious consistency. For the chicken, butcher-cut breasts from Whole Foods or a local shop ensure even thickness. Avoid pre-pounded meat, as it can be overly processed.

No white wine? Substitute with additional chicken broth and 1 tsp lemon juice. Dry mustard powder (at one-third the amount) works in a pinch for the Dijon, though the flavor won’t be as nuanced. The shallots can be replaced with yellow onion at a 1:1 ratio, but shallots’ mild bite is ideal. For a gluten-free version, cornstarch slurry can replace the flour for thickening.

The sauce keeps well, covered, in the refrigerator for 3-4 days. Reheat gently to avoid curdling. Chicken is best cooked fresh but can be stored with the sauce for 2 days. For longer storage, keep components separate and combine when reheating.

Step-by-Step Instructions for Irish Pub-Style Creamy Mustard Chicken

Master the technique for velvety sauce and perfectly cooked chicken every time.

Step 1: Prepare and Sear the Chicken

Pat the 1.5 lb boneless skinless chicken breasts dry with paper towels, then season both sides with the 1 tsp kosher salt and 0.5 tsp freshly ground black pepper. This simple step ensures even browning and optimal flavor penetration.

Heat 1 tbsp unsalted butter and 1 tbsp olive oil in a large skillet over medium-high heat until the butter foams. Add the chicken and cook for 5-6 minutes per side until golden brown and the internal temperature reaches 165°F. Transfer to a plate and tent with foil to retain warmth.

Step 2: Build the Aromatic Base

In the same skillet, reduce heat to medium and add the remaining 2 tbsp unsalted butter. Once melted, add the 2 finely minced shallots and cook for 3-4 minutes until softened and translucent. Avoid browning; you want sweet, mellow shallots to balance the tangy mustards.

Add the 3 minced garlic cloves and 1 tbsp fresh thyme leaves, stirring constantly for 30 seconds until fragrant. Immediately sprinkle the 2 tbsp all-purpose flour over the mixture and cook for 1 minute, stirring to form a light roux. This creates the foundation for your creamy sauce.

Step 3: Deglaze and Develop the Sauce

Pour in the 0.25 cup dry white wine, scraping the browned bits from the bottom of the pan with a wooden spoon. Let it simmer for 2 minutes until reduced by half. This deglazing step captures all the concentrated chicken and shallot flavors.

Add the 0.5 cup chicken broth, 0.25 cup Dijon mustard, and 2 tbsp whole grain mustard. Stir to combine and simmer for 3 minutes until slightly thickened. The combination of smooth Dijon and textured whole grain mustard delivers depth and complexity to the sauce.

Step 4: Finish with Cream and Serve

Reduce heat to low and slowly pour in the 1 cup heavy cream, stirring constantly to prevent curdling. Simmer for 2-3 minutes until the sauce coats the back of a spoon. Taste and adjust seasoning if needed, though the mustards and broth should provide ample flavor.

Return the chicken to the skillet along with any accumulated juices. Spoon the sauce over the chicken and simmer for 1-2 minutes to heat through. Garnish with the 2 tbsp fresh parsley and serve immediately. The sauce should be rich, creamy, and perfectly balanced with tangy mustard notes.

Dietary Considerations for This chicken murphy sauce

Gluten-Free Option

Swap the 2 tbsp all-purpose flour for a cornstarch slurry made with 1 tbsp cornstarch and 1 tbsp cold water. Mix thoroughly and add during the deglazing step. The sauce will thicken just as beautifully without gluten.

Dairy-Free Adaptation

Replace heavy cream with 1 cup full-fat coconut milk for a rich, dairy-free alternative. Use olive oil instead of butter for cooking. The flavor profile will shift slightly but still deliver that creamy, mustard-kissed experience.

Reduced-Fat Version

Use half-and-half instead of heavy cream to reduce calories while keeping the sauce velvety. For extra richness without excess fat, stir in 2 tbsp cream cheese at the end. This keeps the dish lighter but still indulgent. 💪

Low-Carb/Keto Friendly

Skip the flour entirely and thicken the sauce with xanthan gum—just ¼ tsp whisked into 1 tbsp water. This maintains the sauce’s body without adding carbs. Serve over cauliflower rice for a complete low-carb meal.

Lactose-Intolerant Tip

Opt for lactose-free heavy cream brands like Organic Valley. The sauce will taste identical to the original, and you won’t sacrifice texture or richness. Always check labels to ensure true lactose-free status.

Allium-Free Alternative

Omit the shallots and garlic and replace with 1 tsp asafoetida powder (hing) for depth. It adds a savory note without the alliums. This works well for those with sensitivities while maintaining the dish’s complexity.
