Ingredients

For the Base

1 tablespoon Cooking Spray Prevents sticking; any non-stick spray or butter works.
2 tablespoons Unsalted Butter Adds richness and flavor; substitute with olive oil for dairy-free.
1 medium Yellow Onion Provides sweetness and depth; shallots can be used if preferred.
2 cloves Garlic Offers robust aromatic flavor; use garlic powder (1/2 teaspoon for every clove) if unavailable.

For the Sauce

1/4 cup All-Purpose Flour Thickens the sauce; cornstarch is a gluten-free option.
2 cups Whole Milk Contributes creaminess; low-fat or dairy-free milk alternatives can be used.
8 oz Chive and Onion Cream Cheese Adds creaminess and flavor; substitute with plain cream cheese mixed with chopped chives.
1/2 teaspoon Dried Italian Seasoning Adds herbal flavor; a mix of dried basil, oregano, and thyme works well if needed.
1/2 teaspoon Kosher Salt Enhances flavors; use table salt in smaller quantities due to its finer grain.
1/4 teaspoon Crushed Red Pepper Provides heat; omit or reduce for a milder option.

For the Casserole

2 cups Shredded Rotisserie Chicken Offers protein and convenience; any shredded cooked chicken works perfectly.
1 cup Long-Grain White Rice Adds substance; substitute with brown rice or quinoa for a whole grain option.
10 oz Frozen Chopped Spinach Nutritional bulk; you can also use fresh spinach (cooked and drained).
1 tablespoon Fresh Lemon Juice Adds brightness; bottled juice works in a pinch, but fresh is best.
1 teaspoon Fresh Lemon Zest Additives brightness; best used fresh.

For the Topping

1 cup Part-Skim Mozzarella Cheese Melts beautifully for a delicious topping; any melting cheese like cheddar can be substituted.
1/4 cup Grated Parmesan Cheese Enhances flavor with a salty note; nutritional yeast can be a great substitute for dairy-free options.

Method

Steps

Preheat your oven to 350°F (175°C) and coat a 9×13-inch baking dish with cooking spray.
Melt 2 tablespoons of unsalted butter in a large skillet over medium heat. Add in one finely chopped yellow onion and two minced garlic cloves and sauté for about 4 minutes until the onions are translucent.
Sprinkle in 1/4 cup of all-purpose flour, stirring constantly for about 1 minute to form a roux. Gradually add 2 cups of whole milk while whisking until thickened, about 3 minutes. Mix in 8 oz of chive and onion cream cheese and 1/2 teaspoon of kosher salt, stirring until smooth.
Remove from heat and fold in 2 cups of shredded rotisserie chicken, 1 cup of long-grain white rice, 10 oz of drained frozen chopped spinach, and the juice and zest of one fresh lemon. Stir until well combined.
Transfer the mixture into the prepared baking dish, spread evenly, and top with 1 cup of shredded mozzarella cheese and 1/4 cup of grated Parmesan cheese. Bake for 15 minutes.
Switch the oven to broil and broil for an additional 2-3 minutes until the cheese turns golden brown. Watch closely to prevent burning.
