Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish and set it aside.
Cook the spaghetti according to the package directions in a large pot of salted boiling water until al dente. Drain and set aside.
While the spaghetti cooks, heat 1 tablespoon of olive oil in a large skillet over medium heat. Season the chicken breasts with half of the salt, black pepper, and garlic powder. Cook the chicken until golden brown and fully cooked (about 4-5 minutes per side). Remove from the skillet, let it rest for 5 minutes, then chop into bite-sized pieces.
Cut the avocados in half, remove the pit, and scoop the flesh into a small bowl. Add the lemon juice and mash with a fork until smooth. Set aside.
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until it forms a paste without browning. Gradually whisk in the milk and stir constantly until the mixture thickens, about 3-4 minutes.
Reduce the heat to low and stir in 1 3/4 cups of cheddar cheese, the parmesan cheese, paprika, and the remaining salt and pepper until the cheese is fully melted and the sauce is smooth.
In a large mixing bowl, combine the cooked spaghetti, chopped chicken, mashed avocado, and cheese sauce. Mix well to coat all ingredients evenly.
Transfer the mixture to the prepared baking dish, spreading it out in an even layer. Sprinkle the remaining 1/4 cup of cheddar cheese over the top.
Bake in the preheated oven for 20 minutes until the cheese is melted and bubbling.
Remove from the oven and let rest for 5 minutes. Garnish with chopped parsley if desired. Serve hot and enjoy!
