Ingredients You’ll Need

The beauty of this Slow Cooker French Wine and Mustard Chicken Recipe comes through in its simple, high-quality ingredients that work together to build layers of flavor. When shopping, look for fresh herbs and a decent white wine you wouldn’t mind sipping—because its character shines through in the dish.

• Dry white wine: Pinot Grigio or Sauvignon Blanc works perfectly; don’t pick something too sweet or it alters the flavor balance.
• Heavy cream or full-fat coconut milk: Adds richness and makes the sauce incredibly silky.
• Dijon mustard: I like using both smooth and grainy Dijon to give subtle texture and tang.
• Shallots: These lend a mild onion flavor that’s sweeter and less sharp than regular onions.
• Garlic: A couple of cloves minced or grated bring aromatic depth.
• Boneless chicken breasts: Skin on or off—skin on adds extra flavor and keeps it juicy, but either works well.
• Extra virgin olive oil: For browning the chicken before slow cooking.
• Fresh thyme and sage: Thyme’s earthy notes and sage’s peppery, slightly minty aroma transform this dish into a French-inspired delight.
• Salted butter: Adds richness and mouthfeel to the sauce towards the end.
• Freshly grated parmesan cheese: A little umami magic that thickens the sauce and adds depth.
• Kale: Chopped fresh kale brings a nutrient-packed pop of green and a nice mild bitterness.
• Mashed potatoes or steamed rice: Classic comforting sides to soak up that amazing sauce.

Variations

I love experimenting with this Slow Cooker French Wine and Mustard Chicken Recipe—it’s such a flexible base that you can tailor to your tastes or diet. Whether you want to go dairy-free or add in some seasonal veggies, there are plenty of ways to make it your own.

• Dairy-Free Variation: I’ve swapped heavy cream for canned full-fat coconut milk before, and it still produces a creamy, luscious sauce with a subtle coconut hint that pairs surprisingly well with the herbs.
• Vegetable Boost: Sometimes I add mushrooms or pearl onions for extra depth and sweetness; they soak up the wine sauce beautifully.
• Herb Substitutions: If you don’t have fresh sage, rosemary makes a great stand-in, adding slightly piney notes.
• Spice Kick: I occasionally sprinkle in a pinch of smoked paprika or chili flakes for a subtle smoky warmth that livens things up.

How to Make Slow Cooker French Wine and Mustard Chicken Recipe

Step 1: Sear the Chicken to Lock in Flavor

Before you dump everything into the slow cooker, give your chicken breasts a quick sear in olive oil over medium-high heat until golden brown on both sides—about 2-3 minutes per side. This step might feel like extra work, but I promise the difference in flavor and texture is worth it. Searing locks in juices and adds a beautiful caramelized surface that plays wonderfully with the sauce.

Step 2: Prepare the Sauce Base

In your slow cooker, mix together the dry white wine, both kinds of Dijon mustard, heavy cream (or coconut milk), chopped shallots, minced garlic, fresh thyme, and sage along with salt and pepper to taste. This flavorful concoction is the heart of the dish, and you’ll start smelling those cozy French bistro vibes right away.

Step 3: Layer and Cook

Place the seared chicken breasts right into the mustard and wine sauce in the slow cooker. Give the kale a quick rinse and chop, then add it on top—this keeps it from turning too mushy while still absorbing the flavors. Cover and cook on low for about 5 hours. You’ll find the chicken is perfectly tender, and the kale is vibrantly green but melted just right.

Step 4: Finish the Sauce

Once the chicken is cooked through, stir in the salted butter and freshly grated parmesan cheese right in the slow cooker. This last step enriches the sauce and gives it that signature silky, cheesy finish that’s absolutely irresistible. I usually check the seasoning now and add extra salt or pepper if needed—taste as you go!

Step 5: Serve and Enjoy

Spoon generous servings over creamy mashed potatoes or fluffy steamed rice to soak up every drop of the sauce. I often recommend adding a crisp green salad on the side to balance the richness. Get ready for compliments—you’ll have a hard time keeping this one to yourself.

Garnishes

I like to finish this dish with a sprinkle of extra parmesan cheese and a few fresh thyme leaves on top for a pretty presentation and an added herbaceous kick. Sometimes, a tiny drizzle of good-quality olive oil adds that silky sheen I find irresistible.

Side Dishes

This chicken shines when served over creamy mashed potatoes or steamed rice—both are perfect for soaking up the luscious mustard-wine sauce. For something lighter, roasted baby potatoes or a simple green salad with lemon vinaigrette balance the richness beautifully.

Creative Ways to Present

For a special occasion, I like to plate this dish with the chicken sliced, fanned out over the starch, then artistically drizzle the sauce and kale around it. Adding a sprig of thyme or edible flowers makes for a stunning, bistro-style presentation that’ll wow your guests.

Make Ahead and Storage

Storing Leftovers

Your leftovers can be stored in an airtight container in the refrigerator for up to 3 days. I recommend placing the chicken and sauce together, but keeping any mashed potatoes separately to avoid sogginess.

Freezing

I’ve frozen this recipe successfully by dividing into meal-sized portions before cooking or freezing the cooked leftovers. Just make sure to cool it completely before freezing to keep that creamy sauce texture intact.

Reheating

Reheat gently on the stovetop over low heat to avoid breaking the sauce. Adding a splash of cream or water can help loosen the sauce if it thickened in the fridge. Microwave reheating works too, but go slow and stir frequently.
