02 - 1 cup sun-dried tomatoes, drained and chopped
03 - 2 cups baby spinach, roughly chopped
04 - 1 small yellow onion, finely diced
05 - 3 cloves garlic, minced

→ Dairy

06 - 1 cup heavy cream
07 - 1 cup low-sodium chicken broth
08 - 1 cup shredded mozzarella cheese
09 - ½ cup grated Parmesan cheese
10 - 4 oz cream cheese, softened

→ Pantry

11 - 1 teaspoon dried Italian herbs
12 - ½ teaspoon crushed red pepper flakes (optional)
13 - ½ teaspoon kosher salt
14 - ½ teaspoon freshly ground black pepper
15 - 2 tablespoons olive oil

→ Topping

16 - 1 ½ cups Ritz cracker crumbs (about 1 sleeve, crushed)
17 - 4 tablespoons unsalted butter, melted
18 - 2 tablespoons chopped fresh parsley (optional, for garnish)

# Directions:

01 - Preheat oven to 375°F. Lightly grease a 9x13-inch baking dish.
02 - Heat olive oil in a large skillet over medium heat. Cook diced onion until softened, about 3 minutes. Add minced garlic and cook for 1 minute more.
03 - Stir in chopped sun-dried tomatoes and baby spinach. Cook until spinach wilts, approximately 2 minutes.
04 - Reduce heat to low. Add softened cream cheese and stir until fully melted and smooth.
05 - Pour in heavy cream and chicken broth. Add dried Italian herbs, red pepper flakes if using, kosher salt, and ground black pepper. Simmer gently for 2 minutes to combine flavors.
06 - Stir in shredded mozzarella and grated Parmesan cheese until melted and the sauce reaches a creamy consistency.
07 - Add shredded cooked chicken to the sauce, mixing until everything is coated evenly. Remove from heat.
08 - Spread the mixture evenly into the prepared baking dish.
09 - In a small bowl, mix Ritz cracker crumbs with melted unsalted butter. Sprinkle the crumb mixture evenly over the casserole.
10 - Bake uncovered for 25 to 30 minutes until the dish is hot and bubbly and the topping is golden brown.
11 - Allow to rest for 5 minutes before serving. Optionally, sprinkle with chopped fresh parsley.

# Additional Tips::

01 -
  • It comes together in under an hour, and most of that is just the oven doing the work for you.
  • You can assemble it the night before and bake it when guests arrive, so there's barely any stress.
  • The buttery Ritz topping adds this nostalgic crunch that somehow makes everyone fall in love with it.
02 -
  • Don't skip the resting time on the stovetop before baking; rushed sauce that's too thin will pool at the bottom instead of creating that cohesive casserole texture.
  • If your casserole looks watery after baking, it means your chicken was too wet or your sauce was added before it had a chance to set slightly; next time, let the sauce cool a tiny bit in the pan before adding the chicken.
03 -
  • Always taste your sauce before it goes into the casserole dish; this is your chance to adjust seasoning and make sure it tastes bold enough to carry through the baking.
  • If you're short on time, rotisserie chicken plus pre-shredded cheese cuts your prep work in half and still delivers that same wow-factor comfort.
