Ingredients That Make It Special
- Thinly sliced chicken breasts – Using thin, boneless, skinless chicken ensures quick cooking and keeps the meat juicy.
- Heavy cream – Adds a rich, silky texture to the sauce without adding carbs.
- Chicken broth – Gives the sauce a savory foundation and balances the creaminess.
- Xanthan gum (optional) – Helps thicken the sauce, but you can skip it if you prefer a slightly thinner consistency.
- Cheese – Freshly grated mozzarella and parmesan create a smooth, melty topping.
- Mushrooms – Even if you’re not a fan of whole mushrooms, they add flavor to the sauce.
- Butter – Adds richness and helps sear the chicken and vegetables perfectly.
- Simple seasonings, onion, and garlic – Essential for a flavorful, well-rounded dish.
Step-by-Step Instructions
Step 1: Sauté the vegetables
In a large nonstick or cast-iron skillet, melt 2 tablespoons of butter over medium-high heat. Add the mushrooms, finely diced onion, and minced garlic. Sauté for 8–10 minutes, until the mushrooms are tender and the onions turn translucent. Remove the vegetables from the skillet and set aside.
Step 2: Sear the chicken
Using the same skillet, add the remaining 2 tablespoons of butter. Sear the thin chicken breasts for 2–3 minutes per side until lightly golden. The chicken does not need to be cooked through at this stage, as it will finish in the oven.
Step 3: Make the creamy sauce
Return the sautéed vegetables to the skillet. Add the chicken broth, heavy cream, salt, and pepper. Cook over medium heat for 5 minutes, stirring constantly to incorporate all the flavors.
Step 4: Thicken the sauce (optional)
Sprinkle the xanthan gum evenly over the sauce and stir. Let it sit for 5–10 minutes to reach the desired thickness. The sauce should remain creamy but slightly pourable.
Step 5: Assemble the casserole
Place the seared chicken in a greased 9×13-inch casserole dish. Pour the creamy mushroom sauce evenly over the chicken. Sprinkle freshly grated parmesan cheese over the top, then cover with mozzarella. Finish with a pinch of Italian seasoning for added flavor.
Step 6: Bake to perfection
Cover the dish loosely with foil and bake at 400°F for 10 minutes. Remove the foil and continue baking for an additional 8–10 minutes, or until the cheese is melted, bubbly, and the chicken reaches an internal temperature of 165°F. For a golden top, move the dish to the upper rack and broil for 1–2 minutes while keeping a close eye on it.
Tips for the Best Chicken
- Choosing the right chicken: Thinly sliced chicken breasts or cutlets work best. If you only have thicker breasts, slice them lengthwise or pound them to about ¼ inch thick. This ensures even cooking and keeps the meat tender.
- Using chicken thighs: Boneless, skinless thighs are a great alternative. They stay juicier and require slightly longer baking time at 400°F for 20–22 minutes.
- Oil alternatives: Butter gives a rich flavor, but olive or avocado oil can be used if preferred.
- Avoid overcooking: Over-searing or baking too long can make the chicken tough. Lightly sear and finish gently in the oven for optimal tenderness.
Serving Suggestions
This creamy chicken dish pairs beautifully with roasted vegetables like asparagus or Brussels sprouts. A simple green salad on the side rounds out the meal without taking away from the richness of the main dish.
Make-Ahead & Storage
Chicken Lombardy is best served fresh out of the oven but also reheats well. Store leftovers in the refrigerator for up to 3 days. Reheat gently in the oven or microwave to maintain the sauce’s creaminess and keep the chicken tender.
This version of Chicken Lombardy delivers restaurant-quality flavor with minimal effort. The combination of creamy mushroom sauce, melted cheese, and tender chicken makes it a family-friendly favorite, perfect for busy weeknights or casual gatherings.

Creamy Keto Chicken Lombardy – Easy Low-Carb Family Dinner
- Total Time: 55 min
Ingredients
2 lbs boneless, skinless chicken breasts, thinly sliced
½ small onion, finely diced
2 cloves garlic, minced
8 oz mushrooms, sliced
4 tablespoons butter, divided
1½ cups chicken broth
¼ cup heavy whipping cream
½ teaspoon salt
½ teaspoon black pepper
⅛ teaspoon xanthan gum (optional, for thickening)
1½ cups mozzarella cheese, freshly grated
½ cup parmesan cheese, freshly grated
1 teaspoon Italian seasoning
Instructions
- Preheat the oven to 400°F. Grease a 9×13-inch casserole dish.
- In a large cast-iron or nonstick skillet, melt 2 tablespoons butter over medium-high heat. Add mushrooms, onion, and garlic. Sauté 8–10 minutes until mushrooms are tender and onions are translucent. Remove vegetables and set aside.
- Add remaining 2 tablespoons butter to the skillet. Sear chicken for 2–3 minutes per side, just until lightly golden. Do not cook through. Transfer chicken to the prepared casserole dish.
- Return vegetables to the skillet. Stir in chicken broth, heavy cream, salt, and pepper. Cook over medium heat for 5 minutes, stirring constantly.
- Turn off the heat and sprinkle xanthan gum over the sauce if using. Let thicken for 5–10 minutes.
- Pour the sauce over the chicken in the casserole dish. Sprinkle parmesan cheese first, then mozzarella. Top with Italian seasoning.
- Cover loosely with foil and bake for 10 minutes. Remove foil and bake another 8–10 minutes, or until cheese is melted and bubbly and chicken reaches 165°F. Broil 1–2 minutes for a golden finish, if desired.
- Let rest for 5 minutes before serving.
Notes
- Chicken Thighs: Boneless, skinless thighs are an excellent alternative. Bake uncovered at 400°F for 20–22 minutes after searing, then broil briefly if desired.
- Cheese Tips: Freshly grated cheese melts better than pre-shredded and creates a smoother sauce.
- Thickening the Sauce: Xanthan gum is optional. The sauce will still be creamy and flavorful without it.
- Avoid Overcooking: Lightly sear the chicken and finish in the oven to keep it tender.
- Make-Ahead: Store leftovers in the fridge up to 3 days. Reheat gently to prevent the sauce from separating.
