Chef’s Pro Tips for Perfect Results

- Let the dish rest for 5 minutes before serving so the sauce thickens slightly.
Ingredients
For the Chicken:
- 4 boneless, skinless chicken breasts
- 2 tbsp olive oil
- Salt and black pepper, to taste
- 1 tsp paprika
For the Sauce:
- 2 tbsp butter
- 2 cups mushrooms, sliced
- 4 garlic cloves, minced
- 1 cup chicken broth
- 1 cup heavy cream
- 1 tsp Dijon mustard
- ½ tsp dried thyme (or 1 tsp fresh)
- 1 cup shredded mozzarella cheese

Instructions
- Prep the oven: Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
- Season the chicken: Sprinkle chicken breasts with salt, pepper, and paprika.
- Sear the chicken: In a large skillet over medium-high heat, add olive oil and brown chicken on both sides (about 2–3 minutes per side). Transfer to the baking dish.
- Make the sauce: In the same skillet, melt butter. Add mushrooms and cook until golden, about 5 minutes. Stir in garlic and cook for 1 minute.

FAQs

2. Can I lighten it up? Use half-and-half or evaporated milk instead of heavy cream.
3. What cheese works best? Mozzarella for meltiness, Parmesan for flavor—combine both for the win.
4. Can I add veggies? Spinach, peas, or asparagus work beautifully here.
5. How do I prevent dry chicken? Don’t overbake—check internal temperature at 20 minutes.
