Prep Talk: Getting Your Ducks (and Chicken) in a Row
Don’t worry, this isn’t rocket science! Just a little chopping and measuring. Do this first, and the rest is smooth sailing:
- Chop the Chicken: Pat those chicken breasts dry with paper towels (helps it brown better!). Cut them into roughly 1-inch cubes. Season lightly with a pinch of salt and pepper. Set aside.
- Chop the Aromatics: Peel and finely chop the onion. Smash, peel, and mince the garlic cloves. Drain the sun-dried tomatoes (saving that precious tablespoon of oil!) and give them a rough chop.
- Prep the Spinach: No chopping needed! Just have your bag or container of baby spinach ready to go.
- Cheese Please!: Measure out your mozzarella and Parmesan cheese. Keep them separate for now.
- Measure Liquids & Spices: Get your cream cheese (let it soften on the counter while you chop!), heavy cream, and chicken broth measured. Combine all the dried herbs (Italian seasoning, basil, oregano), onion powder, salt, pepper, and red pepper flakes (if using) in a little bowl. This is your flavor bomb!

Let’s Get Baking! Your Step-by-Step Oven Adventure
Preheat your oven to 375°F (190°C). Grab a large (9×13 inch is perfect) baking dish. No need to grease it yet.
- Brown the Chicken (The Flavor Starter!): Heat the olive oil plus that reserved tablespoon of sun-dried tomato oil in a large skillet or Dutch oven over medium-high heat. Add the chicken cubes in a single layer (don’t overcrowd – do it in batches if needed). Cook for about 4-5 minutes, stirring occasionally, until the chicken is lightly browned on all sides but not cooked through completely. It will finish in the oven! Use tongs to transfer the browned chicken to a clean plate. Set aside.
- Sauté the Aromatics: In the same skillet (with all those yummy chicken bits!), add the chopped onion. Cook for about 3-4 minutes over medium heat until softened. Add the minced garlic and cook for just 1 more minute, until fragrant (don’t let it burn!). Stir in the chopped sun-dried tomatoes and cook for another minute.
- Wilt the Spinach: Add the massive handful of baby spinach to the skillet. Stir constantly for about 1-2 minutes, just until it wilts down dramatically. Remove the skillet from the heat.
- Create the Creamy Sauce: Back to the skillet off the heat. Add the softened cream cheese, heavy cream, chicken broth, and ALL of your pre-mixed dried herbs and spices. Stir, stir, stir! It might look a little lumpy at first from the cream cheese, but keep stirring over low heat until it melts into a smooth, beautiful sauce. This is the heart of the dish! Taste it – does it need a touch more salt or pepper? Adjust now.
- Combine Everything (The Grand Mix!): Add the uncooked penne pasta and the browned chicken cubes (with any juices!) to the creamy sauce in the skillet. Stir everything together really well, ensuring the pasta and chicken are coated.
- Bake Time!: Pour this glorious mixture into your 9×13 inch baking dish. Spread it out evenly. Sprinkle the shredded mozzarella cheese evenly over the top, followed by the grated Parmesan.
- Into the Oven: Cover the baking dish tightly with aluminum foil. Pop it into your preheated 375°F oven.
- Bake Covered: Bake for 20 minutes. This steams the pasta and gets everything hot.
- Bake Uncovered (Get That Golden Top!): Carefully remove the foil. Return the dish to the oven, uncovered, for another 15-20 minutes. You’re looking for the pasta to be tender (test a piece!), the sauce to be bubbly around the edges, and the cheese on top to be melted and beautifully golden.
- The Crucial Rest: This is my secret weapon against soupy casseroles! Take the dish out of the oven. Let it rest for 10-15 minutes before serving. Seriously, don’t skip this! The sauce will thicken up perfectly as it sits.

Serving Up Sunshine: How to Plate Your Masterpiece
- Spoon it Out: Use a large serving spoon to scoop generous portions into shallow bowls or onto plates. You want to get all those layers!
- Garnish Glory: Sprinkle generously with fresh chopped basil. That pop of green and fresh flavor is chef’s kiss. For extra color and tang, a few extra chopped sun-dried tomatoes on top look gorgeous.
- Perfect Partners: This casserole is rich and satisfying on its own, but here are some killer sides:
- Crusty Bread: Essential for mopping up every last drop of that creamy sauce! A warm baguette or garlic bread is perfect.
- Simple Green Salad: A light, crisp salad with a simple vinaigrette (like lemon or balsamic) cuts through the richness beautifully.
- Roasted Veggies: Simple roasted asparagus, broccoli, or green beans add a healthy and colorful touch.

Insider Tips & Tweaks: Level Up Your Tuscan Game
- Pasta Perfection: Undercook your pasta? No way! Using it uncooked is the trick here. It absorbs the flavorful sauce as it bakes, becoming perfectly al dente. Trust the process!
- Chicken Swap: Thighs work great too! Use 1.5 lbs boneless, skinless thighs, cubed. They might need an extra minute or two of browning.
- Flavor Boosters:
- Stir in 1/4 cup chopped fresh basil or parsley right before baking for a brighter herb flavor.
- Add 1/2 cup sliced mushrooms when sautéing the onions.
- Use 1 cup of grated Fontina cheese mixed with the mozzarella for extra melty richness.
- Dietary Tweaks:
- Gluten-Free: Use your favorite GF penne pasta. Check broth labels too!
- Dairy-Free: Swap cream cheese for dairy-free cream cheese (Kite Hill or Miyoko’s work well). Use full-fat coconut milk instead of heavy cream. Use vegan mozzarella and Parmesan shreds (Violife is popular). Note: The flavor profile will change slightly.
- Lighter: Use half-and-half instead of heavy cream, and low-fat cream cheese. Reduce the mozzarella slightly. It’ll still be delicious, just less decadent.
- Make Ahead Magic: Assemble the casserole (through step 6) up to a day ahead. Cover tightly and refrigerate. When ready, bake covered at 375°F for 30 minutes, then uncover and bake for 20-25 minutes or until hot, bubbly, and golden. You might need to add 5-10 minutes total.

FAQ: Your Tuscan Chicken Casserole Questions Answered
- Q: Can I use cooked pasta?
- A: You can, but it often ends up mushy. The uncooked pasta absorbing the sauce is key to the texture! If you must, par-cook it (very al dente, about 2-3 minutes less than package directions), rinse in cold water, and reduce the initial covered bake time by 5-10 minutes.
- Q: My sauce seems too thick before baking. Help!
- A: No worries! Just stir in a splash more chicken broth (2-4 tablespoons) until it loosens up. It will thicken as it bakes and rests.
- Q: My sauce is too thin after baking! What happened?
- A: Did you let it rest? That rest time is CRUCIAL for thickening. If it’s still too thin after resting, pop it back in the oven uncovered for 5-10 more minutes. Also, ensure you used full-fat cream and cream cheese – lower fat versions release more water.
- Q: Can I freeze this casserole?
- A: Yes! Assemble completely (through step 6), cover very tightly with foil and plastic wrap, and freeze for up to 2 months. Thaw overnight in the fridge before baking as directed (covered 30 min, uncovered 20-25 min, or until hot throughout). Creamy sauces can sometimes separate slightly upon reheating from frozen, but the flavor is still great.
- Q: What can I use instead of sun-dried tomatoes?
- A: While they add signature flavor, you can substitute with 1 (14.5 oz) can of diced tomatoes, well-drained. The flavor will be different but still tasty. Or, try roasted red peppers, chopped.
- Q: Can I add other vegetables?
- A: Absolutely! Sliced zucchini, bell peppers, or mushrooms added when sautéing the onions work well. Just don’t overload the dish.
