Ingredients
- 6 boneless, skinless chicken thighs
- 1 cup heavy cream
- 1/2 cup chicken broth
- 1/2 cup sun-dried tomatoes, chopped
- 3 cups fresh baby spinach
- 1/2 cup grated Parmesan cheese
- 1/2 cup shredded mozzarella cheese
- 4 cloves garlic, minced
- 2 tablespoons olive oil
- 1 tablespoon Italian seasoning
- 1 teaspoon paprika
- 1/2 teaspoon red pepper flakes (optional)
- Salt and pepper to taste
- Fresh basil for garnish
How to Make Baked Tuscan Chicken Casserole Step by Step
Step 1: Preheat your oven to 375°F (190°C). Season the chicken thighs generously on both sides with Italian seasoning, paprika, salt, and pepper.
Step 2: Heat olive oil in a large oven-safe skillet or Dutch oven over medium-high heat. Sear the chicken thighs for about 3 minutes per side until golden brown. They don’t need to be cooked through — just get that beautiful crust. Remove and set aside.
Step 3: In the same skillet, lower the heat to medium. Add the minced garlic and stir for about 30 seconds until fragrant. Toss in the sun-dried tomatoes and cook for another minute.
Step 4: Pour in the heavy cream and chicken broth. Stir everything together and let it simmer for 2–3 minutes. The sauce will start to thicken slightly and turn a gorgeous creamy color from the sun-dried tomatoes.
Step 5: Add the baby spinach in handfuls, stirring as it wilts down into the sauce. This only takes about a minute. Then stir in the grated Parmesan cheese and red pepper flakes if you want a little heat.
Step 6: Nestle the seared chicken thighs back into the sauce, spooning some of it over the top of each piece. Sprinkle the shredded mozzarella cheese evenly over everything.
Step 7: Transfer the skillet to the oven and bake for 20–25 minutes until the chicken is fully cooked through, the sauce is bubbling, and the mozzarella on top is melted and golden. Garnish with fresh basil and serve straight from the skillet.
This casserole is the kind of meal your whole family will beg you to make again. And there are dozens more just like it inside my complete recipe collection — easy dinners that look and taste like you spent hours in the kitchen.
Frequently Asked Questions
Can I use chicken breasts instead of thighs? You can, but chicken thighs stay juicier and more tender during baking. If you prefer breasts, pound them to an even thickness so they cook evenly and don’t dry out.
What can I serve with Tuscan Chicken Casserole? It’s amazing over pasta, rice, or with a piece of warm crusty bread to soak up every drop of that Tuscan cream sauce. A simple side salad rounds it out perfectly. For more easy pairing ideas, my 90+ recipe digital cookbook has plenty of sides and mains that go together beautifully.
Can I make this casserole ahead of time? Yes. Assemble everything up to the baking step, cover tightly, and refrigerate for up to 24 hours. When you’re ready, just pop it in the oven and add a few extra minutes to the bake time.
Is there a lighter version of this recipe? Swap the heavy cream for half-and-half and use reduced-fat mozzarella. The sauce will be slightly thinner, but the Tuscan flavors will still shine through.
Can I add other vegetables? Absolutely. Artichoke hearts, roasted red peppers, or sliced mushrooms all work wonderfully in this casserole without changing the cooking time.
