Preheat oven to 350ºF. Spray a 2.5 quart casserole dish with cooking spray.
Cook macaroni according to package directions. Drain and set aside.
Meanwhile, cook bacon until crispy - in the oven, microwave or stove top. Drain and when cool, crush or chop into small pieces.
Quickly steam the kale for a couple minutes, until slightly wilted and crisp-tender.
In a large mixing bowl, combine cottage cheese, sour cream, cheddar, egg, salt, pepper, garlic powder. Pour in cooked macaroni, kale and bacon. Stir to combine.
Pour into prepared casserole dish, smoothing top down.
In a microwave bowl, melt the butter. Add in crushed crackers and stir. Pour oven the top of the casserole, evenly.
Place in preheated oven for 40 minutes, or until top is golden brown and everything is heated through.
Scoop into bowls or on plates and enjoy!
