I almost didn’t believe it myself the first time I made it.

This creamy mustard chicken is one of those recipes that looks fancy enough for a date night, but is honestly easy enough for a random Tuesday when you forgot to plan dinner again. 🍗

The sauce is tangy, rich, and a little sharp from the mustard. It’s the kind of sauce you’ll want to pour over literally everything on your plate.

Let’s get into it.

What You’ll Need

Here’s everything you’ll need to grab before you start cooking.

  • 4 boneless, skinless chicken breasts (or thighs, if you prefer)
  • Salt and black pepper, to taste
  • 2 tablespoons olive oil
  • 3 tablespoons butter
  • 4 cloves garlic, minced
  • 1 cup chicken broth
  • 1 cup heavy cream
  • 3 tablespoons Dijon mustard
  • 1 tablespoon whole grain mustard
  • 1 teaspoon smoked paprika
  • 1/2 cup grated Parmesan cheese
  • 1 teaspoon fresh thyme (or 1/2 teaspoon dried)
  • Fresh parsley, chopped, for garnish

That’s it. No obscure ingredients, no special trip to a specialty store.

Tools You’ll Need

  • A large skillet (cast iron or stainless steel works great)
  • Tongs
  • A whisk
  • Cutting board and knife
  • Measuring cups and spoons
  • A meat thermometer (optional, but genuinely useful here)

How to Make Creamy Mustard Chicken

Step 1: Prep the chicken

Pat your chicken breasts dry with a paper towel. This matters more than you’d think.

Season both sides generously with salt and pepper.

If your chicken breasts are thick, slice them in half horizontally so they cook evenly and quickly.

Step 2: Sear the chicken

Heat the olive oil in your skillet over medium-high heat.

Add the chicken and sear for 4-5 minutes per side, until golden brown.

It doesn’t need to be fully cooked through yet. It’ll finish cooking in the sauce.

Remove the chicken and set it aside on a plate.

Step 3: Build the sauce

Lower the heat to medium. Add the butter to the same skillet.

Once melted, toss in the garlic and cook for about 30 seconds, just until it smells amazing.

Pour in the chicken broth and scrape up all those browned bits stuck to the pan. That’s where a lot of the flavor lives.

Step 4: Make it creamy

Whisk in the heavy cream, Dijon mustard, whole grain mustard, and smoked paprika.

Let the sauce simmer for 2-3 minutes until it starts to thicken slightly.

Stir in the Parmesan cheese until it melts completely into the sauce.

Step 5: Finish the chicken

Add the chicken back into the skillet, along with any juices that collected on the plate.

Spoon the sauce over the top of each piece.

Simmer for another 5-7 minutes, or until the chicken reaches 165°F in the thickest part.

Step 6: Serve

Sprinkle with fresh thyme and parsley.

Serve immediately, while the sauce is still warm and glossy.

Pro Tips

  • Don’t skip the sear. Those golden brown bits on the chicken (and the pan) are where most of the flavor comes from.
  • Use room temperature chicken. Cold chicken straight from the fridge cooks unevenly and can leave you with a dry outside and undercooked middle.
  • Whisk the mustard in slowly. Adding it all at once can make the sauce look slightly grainy. A slow whisk keeps it smooth.
  • Taste before you add extra salt. Between the Parmesan, mustard, and broth, this sauce is already pretty well seasoned.
  • Let the chicken rest for 3 minutes before slicing it, if you’re plating it sliced. It keeps the juices locked in.

Substitutions and Variations

This recipe is pretty forgiving. Here are some easy swaps.

  • Chicken thighs instead of breasts for a juicier, richer bite
  • Half-and-half instead of heavy cream for a slightly lighter sauce
  • Honey mustard instead of Dijon for a sweeter twist
  • Coconut milk instead of cream for a dairy-free version (skip the Parmesan or use a dairy-free version)
  • White wine in place of a splash of the broth for extra depth
  • Mushrooms, added when you sauté the garlic, for an earthier variation

Make-Ahead Tips

You can season and sear the chicken up to a day ahead, then store it in the fridge.

When you’re ready to eat, just make the sauce fresh and simmer the chicken in it to finish cooking.

The sauce itself doesn’t hold up quite as well overnight, since cream sauces can separate slightly when reheated. Fresh is best here.

Diet swaps:

  • Low-carb or keto friendly as written
  • Gluten-free naturally, just double check your mustard and broth labels
  • Dairy-free with the coconut milk swap mentioned above

Meal pairing suggestions:

  • Mashed potatoes or roasted baby potatoes
  • Steamed green beans or roasted asparagus
  • A simple arugula salad with lemon vinaigrette
  • Crusty bread, for soaking up every last bit of sauce

Time efficiency tip: Mince your garlic and measure out the mustard and cream before you start cooking. The sauce comes together fast, so having everything ready to go saves you from scrambling.

Leftovers and Storage

Store leftovers in an airtight container in the fridge for up to 3 days.

Reheat gently on the stovetop over low heat, stirring occasionally. Microwaving works too, just do it in short bursts so the sauce doesn’t separate.

This recipe isn’t ideal for freezing. Cream sauces tend to get a little grainy once thawed.

FAQ

Can I use chicken thighs instead of chicken breasts?

Yes, and they’ll actually turn out juicier. Just adjust the cook time slightly, since thighs sometimes take a couple extra minutes.

Is this recipe spicy?

Not at all. The mustard adds tang, not heat. If you want some heat, add a pinch of red pepper flakes to the sauce.

Can I make this dairy-free?

Yes. Swap the heavy cream for full-fat coconut milk, and either skip the Parmesan or use a dairy-free alternative.

What can I use instead of Dijon mustard?

Whole grain mustard works well on its own, or try honey mustard for a sweeter version.

Why did my sauce turn out thin?

It probably needs a few more minutes to simmer. The sauce thickens as it reduces, so give it time before adding more thickener.

Can I double this recipe?

Yes, just use a larger skillet so the chicken has room to sear properly instead of steaming.
