Chicken and Mushroom Skillet in a Creamy Asiago and Mustard Sauce
Recipe Description
Chicken and Mushroom Skillet in a Creamy Asiago and Mustard Sauce is a rich, comforting one-pan dinner that combines golden-seared chicken, tender mushrooms, garlic, herbs, tangy Dijon mustard, and nutty Asiago cheese in a silky cream sauce.
The chicken is lightly seasoned and seared until beautifully golden, while the mushrooms are cooked until deeply browned and savory. Everything comes together in the same skillet, allowing the flavorful browned bits from the chicken and mushrooms to become part of the sauce.
Asiago cheese adds a delicious sharp, nutty flavor that pairs beautifully with Dijon mustard and cream. The result is a restaurant-style dinner that’s surprisingly easy to make at home.
Serve it with mashed potatoes, rice, pasta, roasted vegetables, cauliflower rice, or crusty bread to soak up the creamy sauce.

Ingredients
For the Chicken
1 1/2 pounds boneless, skinless chicken breasts
1/2 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon Italian seasoning
1/2 teaspoon garlic powder
1/2 teaspoon paprika
2 tablespoons olive oil
1 tablespoon butter
For the Mushrooms
8 ounces of cremini or baby bella mushrooms, sliced
1 tablespoon butter
1 small shallot or 1/2 small yellow onion, finely diced
3 cloves of garlic, minced
For the Creamy Asiago Mustard Sauce
1 cup heavy cream
1/2 cup chicken broth
3/4 cup freshly grated Asiago cheese
2 tablespoons Dijon mustard
1 teaspoon whole-grain mustard, optional
1/2 teaspoon Italian seasoning
1/4 teaspoon black pepper
1/4 teaspoon red pepper flakes, optional
1 tablespoon fresh parsley, chopped
1 teaspoon fresh lemon juice
For Garnish
Fresh parsley
Extra grated Asiago cheese
Freshly cracked black pepper
A little lemon zest, optional
Instructions
1. Prepare the Chicken
Pat the chicken breasts dry with paper towels.
If they are very thick, carefully slice them horizontally or gently pound them to create pieces of even thickness.
Season both sides with salt, black pepper, Italian seasoning, garlic powder, and paprika.
Even thickness helps the chicken cook evenly and prevents the thinner parts from becoming dry.
2. Sear the Chicken
Heat a large skillet over medium-high heat.
Add the olive oil and 1 tablespoon butter.
Once the butter is melted and the skillet is hot, carefully add the chicken.
Cook for approximately 4–6 minutes on the first side without moving it too much.
The chicken should develop a deep golden crust.
Flip and cook for another 4–5 minutes, or until nearly cooked through.
Transfer the chicken to a clean plate.
It will finish cooking in the sauce later.
3. Brown the Mushrooms
Reduce the heat slightly to medium.
Add the remaining tablespoon of butter.
Add the sliced mushrooms in a single layer as much as possible.
Cook for 5–7 minutes, stirring occasionally, until the mushrooms release their moisture and develop deep golden-brown edges.
Don’t rush this step. Properly browned mushrooms provide much of the flavor for the finished dish.
4. Add the shallot and garlic.
Add the finely diced shallot or onion.
Cook for approximately 2 minutes until softened.
Add the minced garlic.
Cook for 30–45 seconds until fragrant.
Be careful not to burn the garlic.
5. Deglaze the Skillet
Pour the chicken broth into the skillet.
Use a wooden spoon to scrape the bottom of the skillet and loosen the browned bits.
Those browned pieces contain concentrated flavor and will make the sauce much richer.
Allow the broth to simmer for approximately 1–2 minutes.
6. Make the Cream Sauce
Reduce the heat to medium-low.
Add the heavy cream.
Stir in Dijon mustard and optional whole-grain mustard.
Add Italian seasoning, black pepper, and optional red pepper flakes.
Stir gently and allow the sauce to simmer for approximately 3–4 minutes.
Do not bring the cream to a rapid boil.
7. Add the Asiago Cheese.
Lower the heat.
Gradually add the freshly grated Asiago cheese while stirring.
Continue stirring until the cheese melts smoothly into the cream sauce.
The sauce should become thick, silky, and glossy.
If it becomes too thick, add a few tablespoons of chicken broth.
8. Return the Chicken
Place the seared chicken breasts back into the skillet.
Spoon some of the sauce and mushrooms over the top.
Cover loosely and simmer gently for approximately 4–6 minutes, depending on the thickness of the chicken.
The chicken should reach an internal temperature of 165°F (74°C).
9. Finish the Sauce
Turn off the heat.
Add the fresh lemon juice and chopped parsley.
Taste the sauce and adjust salt and pepper as needed.
The lemon juice adds brightness and balances the richness of the cream and cheese.
10. Serve
Spoon the creamy mushrooms and Asiago mustard sauce over the chicken.
Garnish with fresh parsley, freshly grated Asiago, cracked black pepper, and a little lemon zest if desired.
Serve immediately.
Recipe Notes
Freshly grated Asiago melts more smoothly than pre-shredded cheese and creates a better sauce.
You can substitute Parmesan or Pecorino Romano if Asiago isn’t available, although the flavor will be slightly different.
Cremini or baby bella mushrooms provide excellent flavor, but white button mushrooms work too.
Chicken thighs can be substituted for chicken breasts. They are naturally juicier and particularly delicious in creamy sauces.
Dijon mustard provides acidity and depth rather than making the sauce taste strongly of mustard.
Adding lemon juice at the end prevents the sauce from becoming overly heavy.
Helpful Tips
Don’t overcrowd the skillet when searing the chicken.
Make sure the chicken is dry before seasoning.
Let the chicken develop a crust before flipping.
Brown the mushrooms properly rather than immediately adding the cream.
Keep the sauce at a gentle simmer.
Add the Asiago gradually so it melts evenly.
Freshly grated cheese gives the smoothest consistency.
Taste the finished sauce before adding additional salt because both the broth and cheese can already be salty.
Allow the chicken to rest briefly before slicing if serving it sliced.
How to Get Restaurant-Style Flavor
The first secret is browning the chicken properly.
The second is allowing the mushrooms to caramelize before adding liquid.
The third is deglazing the pan with chicken broth and scraping up the browned bits.
Finally, adding freshly grated Asiago at low heat creates a rich, smooth sauce.
Using all four steps makes a significant difference compared with simply boiling the ingredients together.
Variations
Creamy Spinach Chicken
Add 2 cups fresh baby spinach during the final 2 minutes of cooking.
Bacon Mushroom Chicken
Cook 4 slices of chopped bacon first, remove the bacon, and use some of the rendered fat to cook the chicken. Add the crispy bacon back before serving.
Sun-Dried Tomato Version
Add 1/3 cup chopped sun-dried tomatoes to the mushrooms.
Spinach and Artichoke
Add chopped artichoke hearts and fresh spinach for a creamy vegetable-packed version.
Spicy Mustard Chicken
Add extra red pepper flakes or a pinch of cayenne.
Lighter Version
Replace part of the heavy cream with half-and-half or evaporated milk.
Serving Suggestions
With Mashed Potatoes
Creamy mashed potatoes are perfect for soaking up the Asiago mustard sauce.
With Pasta
Serve the chicken and sauce over fettuccine, penne, or egg noodles.
With Rice
Steamed white or brown rice makes an easy and satisfying side.
With Vegetables
Roasted broccoli, asparagus, green beans, or zucchini pair beautifully with the creamy sauce.
With Crusty Bread
Warm sourdough or French bread is excellent for soaking up every bit of the sauce.
Lower-Carb Option
Serve with cauliflower mash, cauliflower rice, or roasted vegetables.
Make-Ahead Instructions
The chicken can be seasoned and prepared several hours before cooking.
The mushrooms can also be cleaned and sliced ahead of time.
For the best texture, make the sauce shortly before serving.
If you need to prepare the entire dish ahead, cook it slightly under the final desired level and gently reheat before serving.
Add a small splash of chicken broth or cream while reheating if needed.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
Reheat gently in a skillet over low heat.
Add a splash of chicken broth or cream if the sauce has thickened.
Avoid rapid boiling during reheating because the cream sauce can separate and the chicken can become dry.
Freezing is possible, but creamy cheese sauces can change texture after thawing.

Frequently Asked Questions
Can I use chicken thighs instead of breasts?
Yes. Boneless, skinless chicken thighs are an excellent substitute and tend to remain especially juicy.
Can I use Parmesan instead of Asiago?
Absolutely. Parmesan is a very good substitute, although Asiago has a slightly more pronounced nutty and tangy flavor.
Can I use half-and-half instead of heavy cream?
Yes. The sauce will be lighter and slightly less rich. You may need a little extra cheese to achieve the desired consistency.
Why did my sauce become grainy?
The cheese may have been added over too-high heat or added too quickly. Reduce the heat and add freshly grated cheese gradually while stirring.
Can I use pre-shredded cheese?
You can, but freshly grated Asiago or Parmesan generally melts more smoothly.
Can I add vegetables?
Yes. Spinach, broccoli, asparagus, sun-dried tomatoes, artichokes, and zucchini all work beautifully.
Can I make it spicy?
Yes. Add red pepper flakes, cayenne, or a small amount of hot sauce.
Can I make this gluten-free?
Yes. The basic recipe can be gluten-free if you use certified gluten-free chicken broth and seasonings.
Can I make this dairy-free?
The cream, butter, and Asiago would need to be replaced with suitable dairy-free alternatives, which will change the flavor and texture.
Can I prepare it ahead?
Yes. Prepare the components ahead and gently reheat before serving.
How do I thicken the sauce?
Allow it to reduce gently, or add a little more grated Asiago. Avoid adding large amounts of flour directly to the finished sauce because it can create lumps.
What kind of mustard should I use?
Dijon mustard gives the best balance of sharpness and smoothness. Whole-grain mustard can be added for extra texture.
Final Note
Chicken and Mushroom Skillet in a Creamy Asiago and Mustard Sauce is a comforting one-pan meal that feels sophisticated without being difficult to prepare. Golden chicken, deeply browned mushrooms, garlic, Dijon mustard, and nutty Asiago cheese create a sauce that is rich, savory, tangy, and incredibly satisfying.
The secret is to brown each component properly before bringing everything together. Don’t rush the mushrooms, keep the cream at a gentle simmer, and add the cheese over low heat for the smoothest sauce.
