Ingredients You Need

Chicken

2 large boneless skinless chicken breasts, sliced horizontally into 4 thin cutlets
1 teaspoon kosher salt
½ teaspoon black pepper
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon smoked paprika or sweet paprika
2 tablespoons all purpose flour, for light dredging (use gluten free all purpose flour if needed)

Fat and aromatics

2 tablespoons olive oil (or avocado oil)
2 tablespoons unsalted butter
5 to 6 large garlic cloves, minced or pressed
1 small yellow onion or 2 shallots, finely diced

Mushrooms and sauce

12 ounces cremini or baby bella mushrooms, sliced (white button mushrooms also work)
½ teaspoon dried thyme or 1 teaspoon Italian seasoning
1 teaspoon Dijon mustard (adds depth, does not taste like mustard)
1 cup low sodium chicken broth (Better Than Bouillon works great here)
1 cup heavy cream (or half and half for a lighter version)
½ cup freshly grated parmesan cheese (use a block, not pre shredded powdery stuff)
¼ teaspoon red pepper flakes, optional for a gentle kick
Salt and pepper to taste

Finishing touches

2 tablespoons chopped fresh parsley or chives
Juice of ½ small lemon, optional but brightens the sauce

Pantry shortcuts and substitutions

Use pre sliced mushrooms to save time; just rinse quickly and pat dry.
Use jarred minced garlic if you feel tired, though fresh garlic gives better flavor.
Swap parmesan with pecorino romano for a sharper, saltier sauce and reduce added salt.
Replace heavy cream with full fat coconut milk for a dairy light version, and skip the parmesan or use lactose free cheese.

Equipment list

Large skillet or sauté pan, 11 to 12 inches, preferably stainless steel or cast iron
Cutting board and sharp knife
Tongs or a spatula for turning chicken
Wooden spoon or silicone spatula for stirring the sauce
Small whisk for blending broth, cream, and cheese
Measuring cups and spoons

Tips & Mistakes

Pat chicken dry before seasoning so it browns nicely and does not steam.
Slice breasts into thinner cutlets so they cook evenly and stay juicy.
Do not crowd the pan with chicken; cook in batches if needed so you keep a good sear.
Brown mushrooms long enough so they release moisture and pick up color, or the sauce will taste watery.
Keep heat at medium when you add garlic so it turns fragrant but not bitter.
Simmer the cream gently and avoid a hard boil so the sauce stays smooth.
Add parmesan off the heat or on low so it melts instead of clumping.
Taste the sauce at the end and adjust salt, pepper, and acid with a squeeze of lemon.
Use a wooden spoon to scrape browned bits from the pan into the sauce so you catch all the flavor.
Stop cooking chicken when it reaches 165°F in the thickest part so it stays tender and does not dry out.

How to Make Creamy Garlic Mushroom Chicken Recipe

Step 1: Prep the chicken

Lay the chicken breasts flat on a cutting board and slice them horizontally into 4 thinner cutlets. Pat each piece dry with paper towels so the seasoning sticks. Season both sides with salt, pepper, garlic powder, onion powder, and paprika, then dust lightly with flour and shake off any excess.

Step 2: Sear the chicken

Heat the olive oil and 1 tablespoon of butter in a large skillet over medium high heat. When the fat shimmers and a tiny pinch of flour sizzles, add the chicken in a single layer. Sear each side for about 3 to 4 minutes until the surface turns golden and the center cooks through, then move the chicken to a plate and tent loosely with foil.

Step 3: Cook the mushrooms and aromatics

Lower the heat to medium and add the remaining 1 tablespoon of butter to the same skillet. Add the sliced mushrooms and cook, stirring occasionally, for 6 to 8 minutes until they release their liquid and turn deep golden around the edges. Stir in the diced onion and cook 3 to 4 minutes until it softens, then add the minced garlic and cook about 30 seconds until it smells fragrant.

Step 4: Build the sauce base

Sprinkle in the dried thyme or Italian seasoning and stir it into the mushroom mixture. Add the Dijon mustard and red pepper flakes if you use them, and stir again. Pour in the chicken broth while you scrape the browned bits from the bottom of the pan, then let the mixture simmer for 3 to 4 minutes so it reduces slightly.

Step 5: Add cream and cheese

Turn the heat down to medium low and pour in the heavy cream. Stir well and let the sauce bubble gently for 3 to 5 minutes until it thickens enough to coat the back of a spoon. Add the grated parmesan in small handfuls, stirring after each addition until it melts smoothly into the sauce.

Step 6: Adjust seasoning

Taste the sauce and add more salt and pepper if needed. Squeeze in a bit of lemon juice if you like a brighter flavor, then stir in the chopped parsley or chives. If the sauce feels too thick, splash in a little extra broth or cream; if it feels too thin, let it simmer another couple of minutes.

Step 7: Return chicken to the pan

Nestle the seared chicken cutlets back into the skillet, along with any juices from the plate. Spoon the creamy garlic mushroom sauce over the top of each piece. Simmer everything together for 3 to 5 minutes so the chicken warms through and the flavors blend, then turn off the heat and serve.

Variations I've Tried

I sometimes swap chicken with boneless skinless thighs and cook them a bit longer for extra richness. I also use turkey cutlets when I find them on sale, and they soak up the creamy garlic mushroom sauce beautifully. When I want more veggies, I stir in a couple handfuls of baby spinach or steamed broccoli florets right at the end.

I also tried a lighter version with half and half and it still tasted great, just a bit thinner, so I reduced the broth slightly. On busy nights I slice the chicken into bite size pieces before cooking so the dish turns into more of a creamy garlic mushroom chicken skillet that sits perfectly over rice. When I cook for dairy sensitive friends, I use coconut milk and nutritional yeast with extra garlic and herbs, and the pan still ends up almost licked clean.

How to Serve Creamy Garlic Mushroom Chicken Recipe

I love this Creamy Garlic Mushroom Chicken Recipe over fluffy mashed potatoes, buttered noodles, or simple steamed rice so the sauce has something to soak into. You can also spoon it over cauliflower mash or zucchini noodles if you want a lighter base. Add a crisp green salad or roasted green beans on the side to balance the richness and add some crunch.

If you feel extra hungry, warm up some crusty bread or garlic bread and swipe it through the leftover sauce in the pan. I also pack leftovers into meal prep containers with rice and a side of roasted carrots for an easy lunch that still tastes special.

How to store

Cool leftovers to room temperature within 1 hour, then place the chicken and sauce in an airtight container and store in the fridge for up to 3 days.
For the freezer, place cooled chicken and sauce in a freezer safe container or bag, remove as much air as possible, and freeze for up to 2 months.
Thaw frozen portions overnight in the fridge before reheating.
Reheat gently in a covered skillet over low to medium heat with a splash of broth or cream, or use the microwave in short intervals, stirring between bursts so the sauce stays creamy and the chicken does not overcook.
