Preheat the oven to 350 degrees F (175 degrees C).
Fill a large pot with water and add garlic salt; bring to a boil. Cook spaghetti in the boiling water, stirring occasionally, until tender yet firm to the bite, about 12 minutes. Drain and transfer to a large bowl.
While the pasta is cooking, melt butter in a skillet over medium heat. Add onion and saute until lightly browned, 5 to 7 minutes. Add to the pasta.
Add condensed soup, broccoli, Cheddar cheese, cooked chicken, milk, salt, and pepper to the pasta-onion mixture; mix to combine and transfer to a 9x13-inch baking dish.
Bake in the preheated oven for 20 minutes. Sprinkle onions on top and bake another 5 minutes.
