Name: Creamy Chicken Breast and Mushroom Skillet Recipe
Prep time: 10 min
Cook time: 20 min
Total time: 30 min
Ingredients: 4 boneless, skinless chicken breasts (about 1.5 lbs), pounded to even ½-inch thickness; 1 tbsp olive oil; 1 tbsp unsalted butter; 8 oz cremini mushrooms, sliced; 3 cloves garlic, minced; ½ cup chicken broth; 1 cup heavy cream; ⅓ cup grated Parmesan; 1 tsp fresh thyme leaves, plus extra for serving; Salt and black pepper

This creamy chicken breast and mushroom skillet is the kind of dinner that feels like a slow Sunday supper but comes together in under 30 minutes. It’s built on simple ingredients that do a lot of heavy lifting together.

Juicy seared chicken breasts, a rich pan sauce studded with earthy mushrooms, and just enough garlic and thyme to make it interesting. Serve it with mashed potatoes or crusty bread to soak up every drop.

Why This Skillet Works

You get tender, golden chicken with no fussy steps, because the whole thing happens in one pan. The mushrooms release their liquid, brown in the butter, and leave behind a layer of fond that turns into the base of the sauce.

That cream sauce has depth, not just richness. The Parmesan and fresh thyme round out the savory notes, so it tastes like something you let simmer for hours, but the clock says otherwise.

Ingredients

4 boneless, skinless chicken breasts (about 1.5 lbs): pounded to an even ½-inch thickness so they cook evenly
1 tbsp olive oil: for searing, any neutral oil works
1 tbsp unsalted butter: adds richness to the mushroom sauté
8 oz cremini mushrooms, sliced: white button mushrooms work equally well
3 cloves garlic, minced: fresh gives the best savory pop
½ cup chicken broth: helps deglaze the pan and lightens the sauce
1 cup heavy cream: the backbone of the creamy sauce
⅓ cup grated Parmesan: adds a salty, nutty bite
1 tsp fresh thyme leaves: plus extra sprigs for serving
Salt and black pepper: to season at every layer

Variations / Substitutions

Chicken thighs: swap in boneless, skinless thighs; they need an extra 2 to 3 minutes of cook time and taste even juicier.
Mushroom mix: use shiitake, oyster, or portobello instead of cremini for a deeper woodsy note.
Add spinach: stir a handful of baby spinach into the sauce at the very end until just wilted.
Dairy-free version: trade the heavy cream for a full-fat coconut cream and skip the Parmesan; the sauce will be slightly thinner but still creamy.
White wine option: deglaze the pan with ¼ cup dry white wine instead of half the broth for a brighter sauce.

If you like this one-pan approach, the Creamy Garlic Chicken recipe on the site uses a similar method with a spinach and sun-dried tomato twist.

How to Make Creamy Chicken Breast and Mushroom Skillet

Step 1: Sear the Chicken

Preheat a large skillet over medium-high heat and add the 1 tbsp olive oil. Season the chicken breasts on both sides with salt and black pepper. Place them in the hot pan and sear for about 5 minutes on the first side, until the edges turn deeply golden. Flip and cook the second side for another 4 to 5 minutes, then remove the chicken to a plate and set aside.

The surface should be a rich brown, with the meat just shy of cooked through. You are building the first layer of flavor right into the pan.

Step 2: Sauté the Mushrooms

Drop the 1 tbsp butter into the same skillet over medium heat. Once it melts, add the sliced cremini mushrooms in a single layer and let them sit undisturbed for the first 2 minutes, until they start to deepen in color. Stir and continue cooking for about 5 minutes total, until the mushrooms are tender and the edges are caramelized.

They will release their moisture, then shrink and turn a glossy brown. The pan should smell earthy and buttery at this point.

Step 3: Build the Cream Sauce

Add the minced garlic to the mushrooms and cook for 30 seconds, stirring constantly so it doesn’t burn. Pour in the ½ cup chicken broth and scrape up any browned bits from the bottom of the pan with a wooden spoon. Let the broth bubble for 1 minute, then reduce the heat to medium-low. Stir in the 1 cup heavy cream, the ⅓ cup grated Parmesan, and the fresh thyme leaves. Bring to a gentle simmer and cook for 2 minutes, until the sauce coats the back of a spoon.

It should smell rich and savory, with the garlic mellowing into the cream. Keep the heat gentle so the cream thickens without separating.

Step 4: Simmer the Chicken in the Sauce

Return the seared chicken breasts and any juices from the plate to the skillet. Spoon some of the cream sauce over each piece and let everything simmer together over low heat for 5 to 7 minutes, turning the chicken once. The sauce will thicken slightly; check that the thickest part of a breast reads 165°F (74°C) on an instant-read thermometer.

The chicken will look glossy and beaded with creamy sauce, and the mushrooms will be tucked around the pieces. This gentle finish keeps the meat moist while it soaks up the flavor.

Step 5: Spoon Over the Sauce and Serve

Transfer the chicken to a warm serving platter or individual plates. Spoon the creamy mushrooms and sauce generously over the top. Tuck a few extra thyme sprigs around the edges so the plate looks as good as it smells. Serve right away while the sauce is hot and shiny.

Tips for Juicy Chicken and a Silky Sauce

Pound the chicken breasts to an even thickness so the thinner tail end doesn’t dry out before the thick part cooks through.
Don’t crowd the pan when searing; if the pieces are too close together they will steam instead of brown. Cook in two batches if needed.
Use heavy cream that’s at room temperature so it blends into the warm pan without curdling.
After adding the cream, keep the heat at a very low simmer. Boiling hard can cause the sauce to break or turn grainy.

Chicken cooking time by thickness:

Thickness	First Side	Second Side	Internal Temp
½ inch	4 minutes	3 minutes	165°F (74°C)
¾ inch	5 minutes	4 minutes	165°F (74°C)
1 inch	6 minutes	5 minutes	165°F (74°C)

Storing Leftovers

Refrigerate any leftovers in an airtight container for up to 3 days. To reheat, place the chicken and sauce in a small skillet over low heat with a splash of broth or cream. Warm gently while stirring until hot; the sauce will loosen up and stay creamy.

What to Serve With Creamy Chicken Breast and Mushroom Skillet

Buttery mashed potatoes are the obvious choice because they catch every spoonful of sauce. Egg noodles or wide pappardelle also work well, twisting around the mushrooms. For something green, steamed green beans or a simple arugula salad with lemon dressing cut through the richness nicely.

Frequently Asked Questions

Can I use chicken thighs instead of breasts?

Yes. Boneless, skinless thighs work beautifully; cook them until the internal temperature reaches 175°F (79°C) for the most tender texture.

Can I make this with milk instead of heavy cream?

You can, but the sauce will be thinner and more likely to separate. Whisk 2 tsp cornstarch into 2 tbsp cold milk first, then stir it into the simmering sauce to help it thicken.

Can I add white wine to the sauce?

Absolutely. Deglaze the pan with ¼ cup dry white wine after the mushrooms are cooked, letting it reduce by half before adding the broth.

How do I keep the sauce from breaking?

Use room-temperature cream, keep the heat at a gentle simmer the moment the cream hits the pan, and avoid boiling after that point. Stirring off the heat for a few seconds before serving also helps emulsify everything.
