Preheat your oven to 350°F and spray a 9x13 casserole dish with nonstick spray.
In a large bowl, use a wooden spoon to stir together the cream of chicken soup, half of the bacon, cream cheese, sour cream, garlic and onion powder. The cream cheese may remain slightly chunky, this is ok, it will melt when baked.
Add the pasta to the mixture and fold in carefully so you don’t break the noodles up too much.
Add the mixture to your casserole dish and top with the mozzarella and the remaining Monterey Colby jack cheese.
In a small bowl, combine the crackers and butter, folding lightly until you have a fluffy mixture and all crackers are lightly coated in butter and sprinkle over the cheese.
Bake uncovered for 30 minutes or until the crackers are golden and the edges are bubbly.
Garnish with the green onion and remaining bacon and serve warm.
