Shallot Sauce Over Sautéed Chicken with Whole Grain Mustard
Whether it’s a busy Tuesday or you’ve got friends coming over and zero desire to fuss. This chicken with shallot sauce is so easy, make-ahead friendly, and ridiculously delicious.

The flavors? The sweetness of the shallots meets the tang of whole grain mustard in a dreamy, creamy sauce that goes beautifully with juicy, pan-seared chicken. I love serving it with my crispy wedge potatoes and a simple green salad. Cozy, satisfying, and absolutely dinner-party worthy.
It’s one of my go-tos after a day on the river. I love the fact that I can just pop it in the oven while we mix up a fun cocktail together and relive the day’s “big adventure” (which may or may not have involved catching a leaf in the current).
Alright, let’s cut to the mustard—I’ll show you just how easy this shallot sauce is to throw together. Nothing fussy, nothing complicated. Just a few simple steps and you’ve got a cozy, flavor-packed dinner.
Chicken and Shallot Sauce Ingredients

- Chicken breasts – Lightly pounded for even cooking. Chicken thighs work too if that’s what you’ve got (or prefer a little extra juiciness).
- Butter & olive oil – The dream team for sautéing your chicken. Butter adds richness, olive oil keeps things from burning.
- Shallots – Milder and sweeter than onions, they melt beautifully into the sauce without overpowering it.
- White wine – Something dry like Sauvignon Blanc or Pinot Grigio. Don’t go sweet—we’re already getting that mellow sweetness from the shallots.
- Heavy cream – For that velvety, creamy finish.
- Whole grain mustard – Adds texture, tang, and a little bite that plays perfectly with the creamy base. Definitely stick with the whole grain; any other mustard changes the taste of the sauce.
- Salt & pepper – To season the chicken and taste as you go. Don’t skip it!
How to Make Shallot Sauce Over Sautéed Chicken
Pound and trim about 2 pounds of chicken (that’s about 4-6 breasts).
Season generously with salt and pepper on both sides. Don’t be shy here—this is your flavor base.
In a large sauté pan, heat olive oil and butter over medium heat. Once the butter is melted (but not browned), add the chicken.
Cook about 8 minutes per side, depending on thickness, until golden and cooked through. Don’t overcrowd the pan—work in batches if you need to. Add more butter and oil to the pan if it gets dry between batches.

While the chicken’s cooking, finely chop the shallots so they’re ready to go.

Once the chicken is cooked, transfer to a casserole dish and loosely cover with foil to keep warm.
In the same pan, add the chopped shallots and sauté for about a minute.
Slowly pour in the wine, scraping up all the golden browned bits from the bottom of the pan with a wooden spoon. Let it all simmer and reduce by half (about 5 minutes)—this is where the flavor builds.

Stir in the cream, gently simmer for 1-2 minutes. Remove from the heat and whisk in the whole grain mustard until all is combined.

Pour the shallot sauce over the chicken and serve warm.

Make Ahead, Store & Reheat
Make Ahead: This one’s perfect for prepping earlier in the day. You can sauté the chicken ahead of time—just don’t cook it all the way through. About 4 minutes per side, just get that golden sear. Make the sauce, then when it’s almost time for din dins, pour the sauce over the chicken and pop everything in the oven until it reaches full doneness.
Store: Leftovers can be stored in an airtight container in the fridge for up to 3 days. The sauce may thicken as it sits, so when you’re ready to reheat, add a splash of cream, broth, or even water to loosen it up.
Reheat
- Stovetop: Place the chicken and sauce in a skillet over low heat, cover, and warm gently until heated through, stirring occasionally to keep the sauce smooth.
- Oven: Transfer to a baking dish, cover with foil, and warm in a 325°F oven for 15–20 minutes, or until the chicken is hot all the way through.
Avoid high heat—it can cause the sauce to separate or become greasy.
Why Pounding the Chicken Matters
Evenly cooked chicken starts with an even thickness. Pounding helps tenderize the meat and ensures it cooks at the same rate—so you don’t end up with dry edges and an undercooked center.
I like to place the chicken in a zip-top bag (less mess, no splatter) and gently pound the thickest part using a meat mallet or the bottom of a heavy skillet. No need to go wild—just aim for a consistent thickness from end to end.


Substitutions and Variations
This recipe is flexible—here are a few easy swaps and twists to make it work with what you’ve got:
- No wine? (That’s a household problem.) But for the sauce, chicken broth will do just fine. You’ll miss a little of the acidity, but it still turns out rich and flavorful.
- Chicken thighs – Juicier and a bit more forgiving than breasts. Just adjust the cook time.
- Grilled chicken – You can absolutely use grilled chicken, but keep in mind the sauce will miss out on those browned bits from the sauté pan, which add a lot of depth. Still delicious, just a little different.
- Pork chops – This sauce is so good over a pan-seared pork chop.
- Shallots – If you’re in a pinch, a small amount of finely chopped red onion works, but shallots really shine here.
- Want to lighten it up? Use half-and-half instead of heavy cream, though the sauce won’t be quite as rich.
Dinner Party Menu Idea
This dish is absolutely dinner-party worthy—rich, flavorful, and easy to prep ahead so you can actually enjoy your peeps (and that second glass of wine). Here’s a simple menu to build around it:
- Main: Shallot sauce over sautéed chicken with whole grain mustard
- Side: Crispy wedge potatoes or my Parmesan orzo
- Salad: A simple arugula salad with lemon vinaigrette — or pack in the protein with my Party Salad if you’re feeding a hungrier crowd
- Starter: Whipped feta dip with crusty bread or crackers
- Dessert: Something simple—think a scoop of vanilla or gelato
Happy Entertaining!!

- 1 cup dry white wine
- ½ cup heavy cream
- 2 tbsp whole grain mustard
- salt and pepper to season chicken & to taste
Instructions
- Pound the chicken: Place chicken breasts in a zip-top bag and gently pound to an even thickness. Trim as needed.
- Season both sides generously with salt and pepper.
- Heat a large sauté pan over medium heat. Add olive oil and butter. Once the butter is melted (but not browned), add the chicken.
- Cook the chicken for about 8 minutes per side, depending on thickness, until golden and cooked through. Work in batches if needed—don’t overcrowd the pan. Add more olive oil and butter between batches if the pan looks dry.
- Transfer chicken to a casserole dish and loosely cover to keep warm.
- Add chopped shallots to the same pan and sauté for 1 minute.
- Pour in white wine, scraping up any browned bits with a wooden spoon. Simmer and reduce by half, about 5 minutes.
- Stir in the heavy cream and bring just to a gentle simmer.
- Remove from heat and whisk in the whole grain mustard until fully combined. Give it a taste and adjust with more salt and pepper if needed.
- Pour sauce over the chicken. Enjoy!
Notes
- Chicken is fully cooked when it reaches an internal temperature of 165°F. Use a meat thermometer to be sure—it’s the easiest way to avoid overcooking.
- If you’re making this ahead, you can partially cook the chicken, make the sauce, then finish everything together in the oven just before serving.
- The sauce will thicken slightly as it cools. If reheating, add a splash of cream, broth, or water to loosen it up.
