Salt: To taste
Freshly ground black pepper: To taste
Mushrooms & Aromatics
8 ounces mushrooms: Cremini or button mushrooms, sliced
1 small yellow onion: Diced
2–3 garlic cloves: Finely chopped or minced
1 teaspoon fresh thyme: Chopped, or ½ teaspoon dried thyme
Creamy Asiago Mustard Sauce
½ cup heavy cream: Heavy whipping cream can also be used
½ cup freshly grated Asiago cheese
1 tablespoon Dijon mustard
1 tablespoon whole grain or grainy mustard
½ cup chicken broth
¼ cup dry white wine: Optional; use extra chicken broth if preferred
For Cooking & Garnishing
2 tablespoons olive oil or butter
Fresh parsley: Finely chopped, optional for garnish
Extra Asiago cheese: Optional, for serving
Instructions
Prepare the Chicken
Pat the chicken breasts dry with paper towels. Pounding the chicken to an even thickness helps it cook more evenly and prevents thinner portions from becoming dry.
Season both sides generously with salt and freshly ground black pepper. Set the chicken aside while you prepare the skillet.
Sear the Chicken
Heat a large skillet over medium-high heat. Add the olive oil or butter and allow it to become hot but not smoking.
Place the seasoned chicken breasts in the skillet without overcrowding the pan. If your skillet is small, cook the chicken in batches.
Sear the chicken for approximately 4–5 minutes per side, or until golden brown and cooked through. The exact cooking time will depend on the thickness of the chicken.
Transfer the cooked chicken to a clean plate and loosely cover it while you prepare the sauce. The chicken will return to the skillet later.
Cook the Mushrooms and Aromatics
Using the same skillet, add the sliced mushrooms. Cook for approximately 4–5 minutes, stirring occasionally, until they release their moisture and begin to develop a deep golden-brown color.
Add the diced yellow onion and continue cooking for another 2–3 minutes, until the onion becomes soft and translucent.
Stir in the minced garlic and chopped thyme. Cook for approximately 30 seconds, just until the garlic becomes fragrant. Be careful not to burn the garlic, as it can make the sauce bitter.
Make the Creamy Sauce
Pour in the dry white wine, if using. Use a wooden spoon or spatula to gently scrape the browned bits from the bottom of the skillet. These caramelized bits add extra flavor to the finished sauce.
Let the wine simmer for 1–2 minutes to reduce slightly. If you prefer not to use wine, simply add an additional ¼ cup of chicken broth.
Pour in the chicken broth and heavy cream. Stir gently to combine everything in the skillet.
Reduce the heat to medium-low and bring the mixture to a gentle simmer. Avoid boiling the cream aggressively.
Add the Dijon mustard and whole grain mustard. Whisk or stir until both mustards are evenly incorporated into the sauce.
Gradually add the freshly grated Asiago cheese, stirring continuously until it melts into the sauce. Continue cooking gently until the sauce becomes smooth, creamy, and slightly thickened.
Finish the Chicken
Return the seared chicken breasts to the skillet, nestling them into the creamy mushroom sauce.
Spoon some of the sauce and mushrooms over each piece of chicken.
Simmer gently for 2–3 minutes, allowing the chicken to warm through and absorb some of the creamy mustard flavor.
Taste the sauce and adjust the salt and black pepper as needed.
Remove the skillet from the heat and garnish with freshly chopped parsley and additional grated Asiago cheese, if desired.
Serve immediately with your favorite side dish.
Tips
Use Evenly Thick Chicken
Pounding the chicken breasts to an even thickness is one of the easiest ways to achieve juicy, evenly cooked chicken. It also makes the chicken easier to sear without overcooking the thinner edges.
Don’t Overcrowd the Skillet
Give the chicken and mushrooms enough room to brown properly. Overcrowding can cause them to steam instead of sear, reducing the rich flavor and golden color you want.
Brown the Mushrooms Well
Allow the mushrooms to cook until their moisture evaporates and they develop golden edges. This extra step gives the sauce a much deeper savory flavor.
Grate the Asiago Fresh
Freshly grated Asiago generally melts more smoothly into a cream sauce than pre-shredded cheese. Add it gradually over low heat and stir continuously for a silky finish.
Keep the Sauce at a Gentle Simmer
A gentle simmer helps the cream sauce thicken without becoming overly reduced or separated. Once the cheese is added, avoid cooking the sauce over very high heat.
Check Chicken Doneness
Chicken should reach an internal temperature of 165°F (74°C) at the thickest part. A kitchen thermometer is the most reliable way to check doneness.
Variations
Add Spinach
For extra vegetables, stir a few handfuls of fresh baby spinach into the finished sauce. Cook for 1–2 minutes, just until wilted.
Try Different Mushrooms
Cremini and button mushrooms work beautifully, but you can also use baby bella, shiitake, oyster, or a combination of mushrooms for a more complex flavor.
Make It Extra Garlicky
If you’re a garlic lover, increase the garlic to 4 cloves. Add it shortly before the cream so it remains fragrant without becoming bitter.
Use Chicken Thighs
Boneless, skinless chicken thighs can replace chicken breasts. They provide a richer flavor and are naturally more forgiving if cooked for a little longer.
Make It Wine-Free
Simply replace the optional white wine with an additional ¼ cup of chicken broth. The skillet will still have plenty of flavor from the browned chicken, mushrooms, garlic, mustard, and Asiago.
Add a Little Heat
For a spicy variation, add a pinch of red pepper flakes or a small amount of cayenne pepper to the sauce along with the mustard.
Serve It as Pasta
Slice the cooked chicken and toss it with cooked pasta and the creamy mushroom sauce. Add a splash of reserved pasta water if needed to loosen the sauce.
Q&A
Can I make this recipe without white wine?
Yes. White wine is completely optional. Replace it with an additional ¼ cup of chicken broth when deglazing the skillet.
What type of Asiago cheese is best?
Freshly grated Asiago works best because it melts into the sauce nicely. Aged Asiago provides a stronger, sharper flavor, while a younger Asiago creates a milder and creamier result.
Can I use chicken thighs instead of chicken breasts?
Absolutely. Boneless, skinless chicken thighs are an excellent substitute. Adjust the cooking time according to their size and always check that the chicken reaches 165°F (74°C).
How can I thicken the sauce?
Allow the sauce to simmer gently for a few additional minutes before adding the chicken back. The Asiago cheese will also naturally help thicken the sauce as it melts.
Why did my cheese sauce become grainy?
High heat can cause cheese and cream sauces to become grainy or separate. Keep the heat low when adding Asiago and stir gradually until smooth.
What should I serve with this chicken skillet?
Mashed potatoes, pasta, rice, roasted vegetables, steamed broccoli, or crusty bread are all excellent choices. Bread is especially good for soaking up the creamy sauce.
Can I prepare this meal ahead of time?
Yes. You can prepare it ahead and refrigerate leftovers in an airtight container. Reheat gently over low to medium heat, adding a small splash of broth or cream if the sauce becomes too thick.
How should I store leftovers?
Allow the dish to cool before transferring it to an airtight container. Refrigerate and consume within a few days for the best quality. Reheat thoroughly before serving.
