How to Make Tuscan Chicken Pasta Casserole
This casserole is really easy to make. Just follow these simple steps, and you’ll have an amazing dinner ready!
Step 1: Cook the Pasta
Fill your big pot with 4 quarts of salted water. Bring it to a boil. Add 1 pound of penne pasta. Cook for 8-9 minutes until it’s just tender. Drain it well and set it aside.
Step 2: Season and Cook the Chicken
Sprinkle 1 teaspoon salt and ½ teaspoon black pepper on 1.5 pounds of diced chicken. Heat 2 tablespoons of olive oil in your skillet. Cook the seasoned chicken for 6-7 minutes until it’s golden brown.
Step 3: Sauté the Aromatics
Toss 4 minced garlic cloves into the pan with the chicken. Cook for 1 minute. The garlic smells amazing and makes your whole kitchen smell like an Italian restaurant right away!
Step 4: Add Sun-Dried Tomatoes and Spinach
Add ½ cup chopped sun-dried tomatoes and 3 cups fresh spinach to your pan. Cook for 2-3 minutes. Watch the spinach shrink down as it cooks. Mix everything together really well.
Step 5: Create the Creamy Sauce
Pour in 2 cups heavy cream and ½ cup chicken broth. Add 1 teaspoon Italian seasoning and ½ teaspoon red pepper flakes. Let it bubble gently for 3-4 minutes. The sauce will get a bit thicker.
Step 6: Combine with Cheese
Take the pan off the heat. Stir in 1 cup grated Parmesan cheese. Keep stirring until it melts. Your creamy cheese sauce should be smooth and coat everything nicely.
Step 7: Mix Everything Together
Put the cooked pasta into your skillet. Toss it all together. Make sure every piece of pasta gets covered with that delicious creamy sauce. This is where the magic happens!
Step 8: Transfer to Baking Dish
Pour everything into your greased 9×13 baking dish. Spread it out evenly. Sprinkle 2 cups shredded mozzarella cheese all over the top. Cover every spot for the best golden finish!
Step 9: Bake Until Bubbly
Heat your oven to 375°F. Bake for 20-25 minutes without a cover. The cheese gets melty and turns golden brown on top. The edges will bubble and look SO good!
Take it out of the oven. Let it sit for 5 minutes. This helps the sauce settle down a bit. Then it’s easier to scoop out portions without making a mess.

Tips for the Best Tuscan Chicken Pasta Casserole
- Don’t cook the pasta too much when you boil it because it keeps cooking in the oven later.
- Use sun-dried tomatoes packed in oil for way more flavor and moisture.
- Shred your own cheese from a block because it melts better and tastes creamier.
- Go easy on red pepper flakes if kids are eating this dinner tonight.
- Put foil on top if the cheese starts browning too fast while it bakes.
Variations and Substitutions
Want to change things up? This recipe is super flexible! Here are some easy swaps you can try:
- Grab rotisserie chicken from the store to save time on busy nights when you’re rushing around.
- Try kale instead of spinach for thicker greens with more bite and earthy taste, like my Ground Turkey Pasta Bake.
- Switch up the pasta and use rigatoni, fusilli, or bow ties for fun different shapes.
- Make it lighter by using half-and-half instead of heavy cream and adding less cheese overall.

Frequently Asked Questions
Can I make this Tuscan chicken pasta ahead of time?
Yes! Put everything together in the dish. Cover it with foil. Keep it in the fridge for up to 24 hours. Then bake it when you’re ready to eat.
How do I store leftover Tuscan chicken pasta casserole?
Let it cool down first. Put leftovers in a sealed container. Store in your fridge for 3-4 days. Heat up single servings in the microwave when you want some.
Can I freeze this casserole?
You totally can! Wrap the unbaked casserole really well. Freeze for up to 3 months. Take it out the night before and let it thaw in your fridge. Then bake normally.
What should I serve with this dish?
This goes great with garlic bread, Caesar salad, roasted veggies, or simple arugula salad. Any of these will balance out the rich creamy pasta perfectly.
Can I use chicken thighs instead of breasts?
Yep! Boneless skinless thighs work great. They add more flavor and stay juicier. Just know they might need a little more time to cook through.
How do I prevent the casserole from drying out?
Don’t overcook your pasta at first. Don’t leave it in the oven too long. If it looks thick, add more cream before baking. These tips really help!
Can I make this without sun-dried tomatoes?
Sure thing! Use cherry tomatoes or roasted red peppers instead. The flavor will be different but still yummy. You’ll just lose that classic Tuscan vibe a bit.

Notes
- Oil-packed sun-dried tomatoes work best here, so don’t drain all the oil off before you chop them.
- Shred mozzarella yourself from a block for better melting and skip the pre-shredded bags with weird additives.
- Don’t overcook pasta at first, since it cooks more in the oven and can get too soft otherwise.
- Cover with foil if the top browns too fast during baking, so you don’t burn the cheese layer.
- Leftovers taste even better the next day after all the flavors get to know each other overnight!
