Chicken Sun Dried Tomato Casserole - Creamy, Comforting, and Weeknight Friendly
Ingredients
Method
- Prep the oven and pan. Heat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
- Season the chicken. Pat the chicken dry. Season generously with salt, pepper, and half the Italian seasoning.
- Sear for flavor. Warm 1–2 tablespoons olive oil in a large skillet over medium-high heat. Sear the chicken in two batches until lightly browned, about 2–3 minutes per side. It doesn’t need to be fully cooked. Transfer to the baking dish.
- Sauté aromatics. In the same skillet, lower heat to medium. Add butter, then onion. Cook until soft and translucent, 3–4 minutes. Add garlic and cook 30 seconds until fragrant.
- Build the sauce. Stir in flour and cook 30 seconds to make a quick roux (skip if you prefer a thinner sauce). Whisk in chicken stock, scraping up any browned bits. Stir in cream, remaining Italian seasoning, red pepper flakes, and a pinch of salt and pepper. Simmer 2–3 minutes until lightly thickened.
- Add the good stuff. Stir in chopped sun dried tomatoes and half the Parmesan. Fold in spinach just until it wilts (if using frozen, squeeze very dry first). Taste and adjust seasoning.
- Assemble. Pour the sauce over the chicken in the baking dish. Top evenly with mozzarella and the remaining Parmesan.
- Bake. Bake uncovered for 18–22 minutes, until the chicken is cooked through (165°F/74°C) and the top is bubbly and lightly golden.
- Rest and garnish. Let it rest 5 minutes so the sauce settles. Sprinkle with chopped basil or parsley.
- Serve. Spoon over pasta, rice, or alongside roasted vegetables and crusty bread.
What Makes This Special
This casserole balances richness and brightness in a way that keeps every bite interesting. The cream sauce is silky and comforting, but the sun dried tomatoes bring tangy depth that cuts through it perfectly.
Fresh herbs and garlic lift the whole dish, and a layer of melted cheese gives it that irresistible finish. It’s also flexible—you can swap greens, switch the cheese, or use chicken thighs instead of breasts. And best of all, it’s a one-pan bake that reheats beautifully.

Keeping It Fresh
Leftovers keep well for up to 3–4 days in the fridge in an airtight container.
Reheat gently on the stovetop over low heat or in the microwave at 50% power, adding a splash of stock or cream if the sauce tightens up. You can freeze it for up to 2 months; thaw overnight in the fridge before reheating. If you plan to freeze, underbake by a few minutes so the chicken doesn’t overcook when reheated.
Why This is Good for You
Chicken brings lean protein that keeps you full and supports muscle recovery.
Spinach adds iron, folate, and vitamin K, while sun dried tomatoes offer lycopene, an antioxidant linked to heart health. Using a mix of cream and stock keeps the sauce rich without going overboard. You’re getting a balanced plate when you pair it with greens or a side salad.
What Not to Do
- Don’t skip seasoning. Underseasoned sauce makes the whole dish fall flat.
Taste and tweak before baking.
- Don’t overcook the chicken on the stove. A quick sear is enough. It will finish in the oven.
- Don’t use watery spinach. If using frozen, squeeze it well. Excess water will thin the sauce.
- Don’t crowd the skillet. Sear in batches to get good color; steam won’t give you flavor.
- Don’t forget acidity. Sun dried tomatoes add necessary brightness.
If your sauce tastes heavy, a squeeze of lemon at the end helps.
Alternatives
- Lighter version: Use half-and-half instead of heavy cream and reduce cheese by a third. Thicken with a bit of flour as directed.
- Low-carb: Serve with cauliflower rice or zucchini noodles. Skip the flour and rely on gentle reduction to thicken.
- Thighs instead of breasts: Chicken thighs stay extra juicy and are more forgiving if slightly overcooked.
- Different greens: Swap spinach for kale (chopped and sautéed first) or Swiss chard.
- Cheese swap: Try provolone or fontina for a meltier top, or crumble in a bit of goat cheese for tang.
- Dairy-free: Use full-fat coconut milk and a dairy-free mozzarella.
Add 1 teaspoon lemon juice to balance richness.
- Gluten-free: Skip the flour or use a 1:1 gluten-free blend; the sauce will still thicken slightly as it bakes.
- Add-ins: Sautéed mushrooms, artichoke hearts, or roasted red peppers all play nicely with sun dried tomatoes.
FAQ
Can I make this ahead?
Yes. Assemble the casserole up to the point of baking, cover, and refrigerate for up to 24 hours. Add 5–8 extra minutes to the bake time if it’s going into the oven cold.
Do I need to rehydrate dry sun dried tomatoes?
If they’re not packed in oil, soak them in hot water for 10–15 minutes until pliable, then pat dry.
If they’re in oil, just drain and chop—bonus flavor if you use some of that oil to sauté.
How can I thicken the sauce without flour?
Let the cream simmer a bit longer to reduce before assembling. You can also stir in extra Parmesan for body, or whisk in a teaspoon of cornstarch slurry.
What pasta pairs best?
Short shapes like penne, fusilli, or rigatoni grab the sauce nicely. Egg noodles also work well if you want extra comfort vibes.
Can I use rotisserie chicken?
Yes.
Skip the searing step and fold in 3–4 cups of shredded rotisserie chicken when you add the spinach and sun dried tomatoes. Bake for a shorter time, about 12–15 minutes, just to heat through and melt the cheese.
How do I prevent the cheese from getting greasy?
Use low-moisture part-skim mozzarella and grate Parmesan fresh. Avoid overbaking; pull it when the top is just bubbling and lightly golden.
Is there a non-cream option?
Use 1 cup evaporated milk instead of cream for a lighter but still silky texture.
You can also blend 1/2 cup ricotta with stock and Parmesan for a creamy base.
What if my sauce tastes flat?
Add a pinch of salt, a squeeze of lemon, or another tablespoon of Parmesan. A few cracks of black pepper can also sharpen the flavors.
