10 oz Frozen Spinach, thawed and strained really well
2 cloves Garlic, minced
16 oz Sour Cream
1 cup French Fried Onions (divided)
1 pound Spaghetti, cooked to al dente

Instructions

Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the casserole.
Mix Ingredients: In a large bowl, combine the shredded rotisserie chicken, cream of chicken soups, 1 cup of shredded Monterey Jack cheese, thawed and well-drained spinach, minced garlic, sour cream, and 1/2 cup of French fried onions. Stir in the cooked al dente spaghetti, mixing thoroughly until evenly combined.
Assemble Casserole: Grease a 9 x 13-inch baking dish and transfer the chicken and spaghetti mixture into it. Spread the mixture out evenly and smoothly to create an even layer. Sprinkle the remaining 1/2 cup Monterey Jack cheese and remaining French fried onions uniformly over the top.
Bake: Place the baking dish on the center rack of the preheated oven and bake for 45 minutes, or until the cheese topping is melted, bubbly, and golden brown.
Garnish and Serve: Remove the casserole from the oven and optionally garnish with fresh parsley for color and freshness. Serve warm and enjoy your hearty baked chicken spaghetti!

Notes

Make sure to drain the thawed spinach very well to prevent excess moisture in the casserole.
You can substitute Monterey Jack cheese with mozzarella or cheddar for a different flavor profile.
Use freshly minced garlic for best flavor; garlic powder can be a substitute if needed.
This dish can be prepared a day ahead and refrigerated before baking to save time.
For a gluten-free version, use gluten-free spaghetti and ensure cream soups are gluten-free.
French fried onions add a nice crunch; however, you can omit or substitute with breadcrumbs for a different topping texture.
