Herb-Infused Chicken Casserole is a comforting dish that brings together fresh herbs, tender chicken, and melty cheese. Perfect for a cozy dinner, this dish makes great use of simple ingredients to create something special and satisfying.
Chicken breasts are the protein base, providing a lean and tender meat that absorbs the flavors of the herbs beautifully. Olive oil is used for sautéing, adding a subtle richness. Salt and black pepper are essential seasonings that enhance the natural flavors. Fresh rosemary and thyme bring an aromatic herbaceousness that lifts the dish. Baby potatoes add heartiness and soak up the creamy sauce. Cherry tomatoes offer a burst of sweetness and acidity. Chicken broth forms the base of the sauce, while heavy cream adds a luxurious texture. Mozzarella and Parmesan cheese create a gooey, cheesy topping. All-purpose flour is used to thicken the sauce. Garlic and onion provide foundational flavors that deepen the overall taste.
This casserole pairs beautifully with a crisp green salad or steamed vegetables for a complete meal. If you're feeling indulgent, serve it with a warm, crusty bread to soak up the creamy sauce.
First, let’s get that oven preheated to 375°F (190°C) so it’s ready when you are. Grab a large skillet and heat up the olive oil over medium heat. Toss in the diced onion and minced garlic, giving it a good stir until they’re translucent and fragrant.
While that’s cooking, season the chicken breasts with salt, pepper, rosemary, and thyme. Once the onions and garlic are ready, add the chicken to the skillet. Sear the chicken for about 3 minutes on each side to lock in those flavors. After searing, set the chicken aside for later.
In the same skillet, add your halved baby potatoes and cherry tomatoes. Let them cook for about 5 minutes, stirring occasionally. Sprinkle the all-purpose flour over the veggies and stir to coat everything evenly.
Now, slowly pour in the chicken broth and heavy cream, stirring continuously. You’ll notice the mixture will start to thicken – that’s what you want. Once it’s smooth, place the seared chicken back in the skillet and sprinkle the mozzarella and Parmesan cheese over the top.
Transfer the skillet to your preheated oven and let it bake for about 25 minutes. You'll know it's done when the chicken is cooked through and the cheese is golden and bubbly. Let it rest for a good 5 minutes before serving – this helps the flavors to meld together.
