Ingredients

• 4 boneless, skinless chicken breasts (about 1.5–2 pounds)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 teaspoon garlic powder
• 1 tablespoon olive oil
• 2 tablespoons unsalted butter
• 10 ounces cremini or white mushrooms, sliced
• 1 small yellow onion, finely chopped (optional but recommended)
• 2 cloves garlic, minced
• 1/2 cup low-sodium chicken broth
• 1 teaspoon Dijon mustard
• 1/2 cup heavy cream or half-and-half
• 1 teaspoon Worcestershire sauce
• 1 tablespoon fresh thyme leaves or 1/2 teaspoon dried thyme
• 6–8 slices Swiss cheese (or about 1 1/2 cups shredded)
• 1/4 cup grated Parmesan (optional, for extra savoriness)
• Fresh parsley, chopped, for garnish
• Cooking spray or a light brush of oil for the baking dish

Step-by-Step Instructions

1. Prep the oven and dish: Preheat to 400°F (200°C). Lightly oil a 9×13-inch baking dish so nothing sticks.
2. Season the chicken: Pat the chicken breasts dry.

   Sprinkle evenly with salt, pepper, and garlic powder on both sides.

3. Brown the chicken: Heat the olive oil in a large skillet over medium-high. Sear chicken 2–3 minutes per side until lightly golden. You’re not cooking it through—just getting color.

   Transfer to the baking dish.

4. Sauté the mushrooms and aromatics: In the same skillet, reduce heat to medium and add the butter. Toss in mushrooms and onion with a pinch of salt. Cook 5–7 minutes, stirring occasionally, until the mushrooms give off their moisture and brown around the edges.

   Add minced garlic and cook 30 seconds more.

5. Build the sauce: Pour in chicken broth, scraping up any browned bits. Stir in Dijon, Worcestershire, thyme, and cream. Simmer 2–3 minutes until slightly thickened.

   Taste and adjust salt and pepper. For extra depth, stir in Parmesan.

6. Assemble the bake: Spoon the mushroom mixture evenly over the chicken. Lay Swiss cheese slices on top so each breast is covered.
7. Bake: Place the dish on the center rack and bake 18–22 minutes, or until the chicken reaches 165°F (74°C) in the thickest part.

   The cheese should be melted and bubbling.

8. Rest and garnish: Let it sit 5 minutes so the juices settle. Scatter with chopped parsley for a fresh finish.
9. Serve: Spoon extra mushroom sauce over each piece. It’s great with rice, mashed potatoes, buttered noodles, or roasted green beans.

Keeping It Fresh

• Storage: Cool completely, then refrigerate in an airtight container for up to 4 days.
• Reheat: Warm covered at 325°F (165°C) for 12–15 minutes, or microwave in short bursts so the chicken stays juicy.
• Freezing: Freeze tightly wrapped portions for up to 2 months.

  Thaw overnight in the fridge and reheat gently.

• Make-ahead tips: Sauté the mushrooms and mix the sauce up to 2 days ahead. Store separately and assemble just before baking.

Why This is Good for You

• Protein-rich: Chicken breast delivers lean protein to keep you satisfied.
• Mushrooms matter: They bring fiber, antioxidants, and umami without many calories.
• Balanced fats: A modest amount of cream and cheese adds richness, helping with fullness and flavor.
• Lower-sodium option: Use low-sodium broth and taste as you go to keep salt in check.

Pitfalls to Watch Out For

• Dry chicken: Overbaking is the main culprit. Use a thermometer and pull at 165°F.
• Watery mushrooms: Don’t crowd the pan.

  Let them brown so the sauce isn’t thin.

• Bland sauce: Season in layers—salt the mushrooms, taste the sauce, and adjust before baking.
• Rubbery cheese: Swiss melts well, but avoid broiling too long. Gentle heat keeps it creamy.

Alternatives

• Cheese swaps: Try provolone, Gruyère, or mozzarella for different melt and flavor.
• Dairy-light: Use half-and-half or evaporated milk. For a lighter sauce, stir in a splash of milk and skip Parmesan.
• Gluten-free: This recipe is naturally GF if your broth and Worcestershire are certified gluten-free.
• Herb variations: Rosemary, tarragon, or Italian seasoning all work.

  Add a squeeze of lemon for brightness.

• Veg boosts: Add spinach to the sauce at the end, or layer in sliced zucchini for extra veg.
• Protein swap: Use boneless, skinless thighs (adjust bake time) or turkey cutlets.

FAQ

Can I use canned cream of mushroom soup instead of making the sauce?

Yes. Use one 10.5-ounce can plus 1/3 to 1/2 cup milk or broth to loosen it. Season to taste and proceed with assembling and baking.

How can I tell when the chicken is done if I don’t have a thermometer?

Cut into the thickest part; the juices should run clear and the meat should be opaque, not pink.

Aim for a total bake time of 18–22 minutes after searing, depending on thickness.

What’s the best way to slice mushrooms for this?

About 1/4-inch thick. Thin enough to cook quickly, but thick enough to keep a meaty bite in the sauce.

Can I make this in a skillet instead of a baking dish?

If your skillet is oven-safe and large enough, yes. Sear the chicken, make the sauce, top with Swiss, and transfer the skillet straight to the oven.

How do I prevent the sauce from getting too salty?

Use low-sodium broth, taste after reducing, and remember Swiss can be salty.

Add salt at the very end if needed.

What sides go best with this?

Mashed potatoes, buttered egg noodles, rice pilaf, roasted asparagus, or a simple green salad all pair nicely with the creamy sauce.

Can I add white wine?

Absolutely. Replace 1/4 cup of the broth with dry white wine and let it simmer for a minute to cook off the alcohol before adding cream.
