Ingredients:
You don’t need a gourmet grocery haul for this one. Most of the ingredients are probably already hanging out in your pantry or fridge.
- 3 skinless, boneless chicken breast halves – you can also use chicken thighs for extra juiciness.
- 1 teaspoon kosher salt
- ¼ teaspoon freshly ground black pepper, or more to taste
- 2 tablespoons olive oil
- 1 medium white onion, chopped
- 2 tablespoons chopped fresh parsley
- 1 teaspoon poultry seasoning
- ¼ teaspoon cayenne pepper – just enough to give it a warm little kick.
- 1 (7 oz) can whole mushrooms, drained (or sub in fresh mushrooms)
- 1 (10.5 oz) can condensed cream of chicken soup
- 1 cup heavy cream – the base of all that luscious, creamy goodness.
- ¼ cup buttermilk – adds a subtle tang that balances out the richness.
- 4 slices Swiss cheese – for that melty, cheesy finish.
✅ Pro Tip: No buttermilk? Mix 1/4 cup milk with 1 teaspoon vinegar or lemon juice, let it sit for 5 minutes, and voilà—DIY buttermilk. Here’s how to make buttermilk at home if you need more help.
Directions:
This recipe might sound indulgent, but the actual process is so simple you could do it on autopilot (which, let’s face it, you might be some nights).
Step 1: Season & Preheat
Start by preheating your oven to 350°F (175°C). Season the chicken breasts generously with salt and pepper. That’s your flavor base right there.
Step 2: Sauté Your Aromatics
Heat the olive oil in a large skillet over medium-high heat. Add your chopped onion and cook for about 5 minutes, or until they turn soft and semi-transparent. Stir in the chopped parsley so it gets a chance to bloom in the heat.
Step 3: Brown the Chicken
Place the seasoned chicken into the skillet and brown each side—about 5 minutes per side. You’re not cooking it through yet, just giving it some golden color and sealing in the juices.
Step 4: Layer & Season
Once the chicken is browned, sprinkle it with poultry seasoning and cayenne pepper. Then, transfer it to a 9×13-inch baking dish. Cover the top with your mushrooms (canned or sautéed fresh). Set aside.
Step 5: Make the Sauce
In a medium bowl, combine the condensed cream of chicken soup, heavy cream, and buttermilk. Stir in the sautéed onions and parsley. Pour this creamy, dreamy mixture over the chicken and mushrooms.
Step 6: Add Cheese
Lay the Swiss cheese slices on top, covering the entire surface. Cheese blanket = comfort.
Step 7: Bake It Up
Bake uncovered for 1 hour and 35 minutes. Let it rest for 15 minutes before serving. The result? A bubbling, golden Creamy Chicken and Mushroom Bake that smells and tastes amazing.

Tips for the Best Creamy Chicken and Mushroom Bake
- Use chicken thighs for extra flavor and tenderness, but chicken breasts work great too.
- Brown your chicken and mushrooms before baking — it adds depth and brings out more flavor.
- Don’t skip the garlic — fresh minced garlic gives the sauce a rich, savory base.
- Deglaze the pan with a splash of white wine or chicken broth after sautéing mushrooms for added flavor.
- Add a touch of Dijon mustard or cream cheese to the sauce if you want more tang and richness.
- Use fresh herbs like thyme or parsley for brightness — sprinkle some on top just before serving.
- Let it rest for 5 minutes before serving so the sauce thickens and flavors settle.
- Double the sauce if you’re serving it over pasta, rice, or mashed potatoes — it’s that good!

Keep leftovers in an airtight container in the fridge for 3-4 days. Reheat in the microwave or oven with a splash of milk or cream to bring the sauce back to life.
