- 3 cloves garlic, minced
- 1 tsp Italian seasoning
- Salt and pepper, to taste
- 1/2 cup sun-dried tomatoes, chopped (oil-packed, drained)
- 3 cups fresh spinach (or 1 cup frozen, squeezed dry)
For the sauce:
- 2 tbsp butter
- 2 tbsp all-purpose flour (or GF flour blend)
- 1 1/2 cups milk
- 1/2 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 1/4 tsp red pepper flakes (optional, for heat)

Step-by-Step Instructions
1. Sauté the Chicken and Veggies
- Preheat your oven to 375°F (190°C).
- In a large skillet, heat 1 tbsp olive oil over medium heat.
- Add chicken, season with salt, pepper, and Italian seasoning, and cook for 5–6 minutes until lightly browned.
- Add onions and cook another 2 minutes.
- Stir in garlic and cook 30 seconds until fragrant.
- Mix in sun-dried tomatoes and spinach, and cook just until spinach wilts.
Don’t overcook the chicken—it will finish baking in the oven.
2. Make the Creamy Sauce
- In a separate saucepan (or clean out your skillet), melt 2 tbsp butter.
- Whisk in 2 tbsp flour and cook for 1 minute to create a roux.
- Slowly whisk in milk and cream, stirring constantly until smooth.
- Add Parmesan, red pepper flakes, and a pinch of salt and pepper.
- Simmer for 2–3 minutes until slightly thickened.
Don’t boil the sauce—keep it low and slow so it stays creamy and smooth.
3. Assemble the Casserole
- Pour the chicken mixture into a 9×13″ baking dish.
- Pour the cream sauce evenly over the top.
- Sprinkle with shredded mozzarella.
4. Bake Until Golden and Bubbly
- Bake uncovered for 25–30 minutes, or until cheese is melted and lightly golden.
- Optional: Broil for the last 2–3 minutes for a golden top.
5. Garnish and Serve
- Let rest 5 minutes, then sprinkle with fresh chopped basil or parsley.
- Serve hot and cheesy with your favorite sides!
How to Serve
This casserole is rich and satisfying on its own, but it also plays well with others:
Perfect Pairings:
- Garlic bread or crusty baguette
- Caesar salad or lemon vinaigrette greens
- Mashed potatoes or cauliflower mash
- Pasta or egg noodles
- Rice, quinoa, or farro
Hosting guests? Serve in individual ramekins for an elegant dinner-party twist.
Want to keep it low-carb? It’s perfect with a big pile of roasted broccoli or zucchini noodles.
Tips for Success
- Use cooked chicken to speed things up: Rotisserie chicken works great!
- Drain your sun-dried tomatoes: Oil adds flavor, but too much will make your sauce greasy.
- Add the cheese gradually: For a silky sauce, stir the Parmesan in once the milk mixture is hot—but not boiling.
- Use fresh spinach if you can: It adds brightness and wilts beautifully into the casserole.
- Broil to finish: Want that golden cheesy top? Broil the last 2–3 minutes—watch closely!
Bonus idea: Add mushrooms or roasted red peppers for extra veggie action.
