  • 1 (14 oz) rotel tomatoes with green chilies
  • 2 ½ cups chicken (cooked and shredded)

Instructions

  • Preheat the oven to 350°F. Lightly grease a 13x9-inch baking dish with nonstick cooking spray.

  • In a large pot over medium-high heat, melt butter and cook onions, garlic, and bell pepper until tender. about 5-6 minutes. Then, add Italian seasoning, paprika, black pepper, salt, cream of mushroom soup, and 1¼ cups of cheese. Cook until the cheese is completely melted. Remove from heat.

Notes

  • Cook and shred your chicken ahead of time or use leftover rotisserie chicken!
  • You can use cheddar, Monterey Jack, or Mexican cheese (or a mix of them) in this dish.
  • Cook your spaghetti al dente. It will finish cooking in the oven, keeping the casserole from getting mushy.
  • If you want a creamier sauce, add extra condensed soup or a splash of heavy cream.
  • Add toppings like fresh parsley, crispy bacon bits, or extra cheese.
