Tips for the Best Creamy Chicken Spaghetti Texture and Flavor

• Use freshly shredded cheese: It melts better than pre-packaged varieties.
• Don’t overcook the spaghetti before baking—it will continue to soften in the oven.
• Add spice with a pinch of cayenne or a splash of hot sauce for grown-up heat.
• For creamier results, add a dollop of sour cream or cream cheese to the mixture.

This is also a perfect recipe to sneak in some veggies—just sauté bell peppers, mushrooms, or spinach with the onions!
