Spinach: 6 oz frozen chopped spinach (thawed and squeezed dry) or 2 cups fresh baby spinach
Sun-Dried Tomatoes: 1 jar (8 oz), drained and chopped (reserve 1–2 tbsp oil if available)
Creamy Sauce & Cheeses
Cream Cheese: 3–4 oz, softened
Heavy Cream: 1/3 to 3/4 cup
Mozzarella Cheese: 3/4 to 1 cup, shredded (divided)
Parmesan Cheese: 1/3 to 1/2 cup, grated
Seasonings & Aromatics
Garlic: 3–4 cloves, minced
Italian Seasoning: 1–2 teaspoons
Onion Powder: 1/2 to 1 teaspoon
Paprika: 1/2 teaspoon
Chili Powder: 1/4–1/2 teaspoon (optional heat)
Salt and black pepper to taste
Fresh parsley or basil for garnish
Instructions
Preheat your oven to 190°C (375°F). Lightly grease a casserole or baking dish.
Season the chicken fillets with salt, pepper, paprika, and a sprinkle of Italian seasoning.
Heat a skillet over medium heat and lightly sear the chicken for 2–3 minutes per side until lightly golden (it does not need to be fully cooked). Set aside.
In the same skillet, add garlic and sauté for about 30 seconds until fragrant.
Lower the heat and add cream cheese, stirring until it begins to melt. Slowly pour in the heavy cream, whisking until smooth and creamy.
Add Italian seasoning, onion powder, chili powder (if using), salt, and pepper. Stir well to combine.
Mix in spinach and sun-dried tomatoes, allowing everything to warm through and blend into the sauce.
Stir in half of the mozzarella and parmesan cheese until melted and smooth.
Place the seared chicken in the baking dish and pour the creamy Tuscan sauce evenly over the top.
Sprinkle the remaining mozzarella and parmesan over the casserole.
Bake for 25–30 minutes, or until the chicken is fully cooked and the top is bubbling and golden.
Remove from the oven and let it rest for 5–10 minutes. Garnish with fresh parsley or basil before serving.
Tips
Slice chicken evenly so it cooks at the same rate.
Searing the chicken first adds extra flavor and texture.
Always squeeze excess moisture from spinach to avoid a watery sauce.
Use full-fat cream cheese for the creamiest texture.
Let the sauce simmer gently to prevent splitting.
Reserve sun-dried tomato oil for extra depth of flavor.
Don’t overbake or the chicken may become dry.
Allow the casserole to rest before serving so the sauce thickens.
Use freshly grated parmesan for better melting and flavor.
Adjust seasoning at the end after tasting the sauce.
Variations
Add mushrooms or zucchini for extra vegetables.
Swap chicken with shrimp for a seafood version.
Use turkey breast instead of chicken for a leaner option.
Replace heavy cream with half-and-half for a lighter sauce.
Add spinach and ricotta for an even creamier texture.
Include red pepper flakes for a spicier kick.
Top with breadcrumbs for a crispy baked crust.
Use kale instead of spinach for a heartier green.
Add pasta or gnocchi to turn it into a complete one-pan meal.
Swap mozzarella with provolone or fontina for deeper flavor.
