Instructions

Prepare the Chicken:

1. Slice the chicken breasts into 2-3 thinner pieces. Place each slice between layers of plastic wrap and pound them to ¼-inch thickness. (Pro Tip: Using the textured side of a meat tenderizer speeds up the process.)
2. Pat the chicken dry and season both sides with salt, pepper, garlic powder, and Italian seasoning. Mix the flour with Parmesan cheese and dredge the chicken in this mixture.
3. Heat 3 Tablespoons of olive oil and 1 Tablespoon of butter in a skillet over medium-high heat. Sear the chicken for about 3 minutes on each side until golden brown. (Pro Tip: Adjust the heat as needed to avoid burning and add more olive oil if necessary.)
4. Remove the chicken from the skillet, tent with foil, and set aside. (It will finish cooking in the oven.)

Caramelize the Onions:

1. Slice the onions into ¼-inch rings. (Avoid slicing them too thin as they will shrink while cooking.)
2. In the same skillet, melt 2 Tablespoons of butter with 1 Tablespoon of olive oil over medium heat. Use a spatula to scrape up any browned bits from the chicken (“fond”) for added flavor.
3. Add the onions to the skillet, tossing to coat them evenly. Cook for 5 minutes to soften.
4. Stir in soy sauce, rosemary, thyme, and sage. Cover the skillet, reduce the heat to low, and cook for 30 minutes, stirring occasionally.
5. Remove the cover and increase the heat to medium. Continue cooking, stirring frequently, for another 10 minutes.

Make the Sauce:

1. Preheat your oven to 475°F (245°C).
2. Add the minced garlic and white wine to the skillet. Cook uncovered until the wine has reduced almost completely, about 10 minutes.
3. Stir in the flour and cook for 1-2 minutes until the raw flour smell dissipates.
4. Gradually add the beef broth, chicken broth, and beef bouillon cube. Increase the heat to medium-high and bring the mixture to a gentle boil. Let it simmer and thicken for 3-5 minutes. Remove the skillet from heat.

Bake:

1. If your skillet isn’t oven-safe, transfer the contents to a casserole dish.
2. Nestle the seared chicken into the skillet or casserole dish and top with mozzarella cheese.
3. Bake for 15-20 minutes, or until the cheese is melted, golden, and bubbling.
4. Garnish with fresh thyme if desired. Serve hot and enjoy!

FAQs

Can I make this dish ahead of time?
Yes! Prepare and sear the chicken and caramelize the onions in advance. Store them separately in the refrigerator and assemble the dish just before baking.

What can I use instead of beef bouillon?
You can use a teaspoon of Worcestershire sauce or an extra ½ teaspoon of soy sauce.

Can I freeze leftovers?
Absolutely. Store in an airtight container for up to 3 months. Reheat in the oven or microwave until warmed through.

Serving Suggestions

• Pair with creamy mashed potatoes or buttery egg noodles for a complete meal.
• Serve alongside a crisp green salad or roasted vegetables.
• Add a slice of toasted baguette to soak up the flavorful sauce.
