Creamy Chicken and Mushroom Skillet with Asiago Mustard Sauce

Chicken and Mushroom Skillet in a Creamy Asiago and Mustard Sauce

This whole meal comes together in about 30 minutes, which makes it a fantastic option for a busy weeknight when you still want something that feels a little special. The chicken stays tender, the mushrooms get that lovely golden-brown edge, and the sauce brings everything together with a creamy, tangy finish that coats every bite.

I first made a version of this after a trip to the Midwest where I had a similar dish at a small farm-to-table restaurant. The combination of earthy mushrooms and sharp Asiago cheese with a hint of mustard stuck with me. This skillet version is my simplified take on that memory, and it always delivers that same cozy, satisfying feeling.

Why You’ll Love This Recipe

• Everything cooks in one skillet, so cleanup is quick and easy
• The creamy Asiago and mustard sauce feels luxurious without being complicated
• Chicken breasts stay juicy thanks to a simple searing technique
• Mushrooms add an earthy depth that pairs beautifully with the cheese
• It is the kind of meal that feels like a warm hug on a cold evening

Ingredients

• 2 boneless skinless chicken breasts (about 1 pound total), halved horizontally for even cooking
• Salt and black pepper to taste
• 2 tablespoons olive oil, divided
• 8 ounces cremini mushrooms, sliced
• 2 cloves garlic, minced
• ½ cup chicken broth, low sodium preferred
• ½ cup heavy cream
• ¼ cup grated Asiago cheese
• 1 tablespoon Dijon mustard
• 1 teaspoon whole grain mustard
• 1 tablespoon fresh thyme leaves for garnish

Instructions

• Season the chicken pieces generously with salt and black pepper on both sides
• Heat 1 tablespoon olive oil in a large skillet over medium-high heat until shimmering
• Sear the chicken for 4 to 5 minutes per side until golden brown and cooked through, then transfer to a plate and set aside
• Add the remaining olive oil to the same skillet and toss in the sliced mushrooms, cooking for 5 to 6 minutes until they release their liquid and turn golden brown
• Stir in the minced garlic and cook for another 30 seconds until fragrant
• Pour in the chicken broth and scrape up any browned bits from the bottom of the pan with a wooden spoon
• Reduce the heat to medium-low and stir in the heavy cream, grated Asiago cheese, Dijon mustard, and whole grain mustard until the sauce is smooth and the cheese has melted
• Return the chicken to the skillet and let it simmer gently in the sauce for 2 to 3 minutes, turning once to coat
• Sprinkle fresh thyme leaves over the top before serving

Pro Tips

• Slicing the chicken breasts horizontally into cutlets ensures they cook evenly and quickly without drying out
• Do not overcrowd the mushrooms in the skillet, give them space so they brown properly instead of steaming
• For the best texture, grate the Asiago cheese yourself from a block instead of using pre-shredded, it melts much smoother
• The sauce will thicken as it sits, so if it seems too thin at first, let it simmer for an extra minute before adding the chicken back
• Let the chicken rest for a couple of minutes after searing to keep the juices locked in

Variations

• Swap the chicken for boneless pork chops or turkey cutlets for a different protein option
• Add a handful of fresh spinach right before serving and let it wilt into the sauce for extra color and nutrients
• Use half-and-half instead of heavy cream for a slightly lighter sauce that still tastes creamy
• Substitute the cremini mushrooms with shiitake or oyster mushrooms for a more intense, earthy flavor

Frequently Asked Questions

• Can I use chicken thighs instead of breasts? Yes, boneless skinless thighs work well, just adjust the cooking time slightly as they may need a minute or two longer to cook through
• What can I serve with this Chicken and Mushroom Skillet? It pairs beautifully with mashed potatoes, egg noodles, or a side of steamed green beans
• How do I store leftovers? Keep them in an airtight container in the refrigerator for up to 3 days and reheat gently on the stovetop or microwave
• Can I make this dairy-free? That is tricky because the Asiago cheese is central to the flavor, but you could try a dairy-free cream alternative and a sharp vegan cheese
• Why did my sauce turn out grainy? That usually happens from overheating the cream or using pre-shredded cheese with anti-caking agents, so grate fresh cheese and keep the heat low
• Can I freeze this dish? The sauce may separate upon thawing, but it is still safe to freeze and can be whisked back together when reheated
