Cook the pasta according to the package directions in a large pot of salted boiling water.
Once the pasta is cooked, rinse it with cold water and drain it in a colander.
Add the cottage cheese, milk, onion powder, garlic powder, salt, and cheddar cheese powder to a blender or food processor.
Blend the ingredients until smooth.
Add the drained cooked pasta to a large bowl. Then, add the blended sauce and shredded cheddar cheese to the bowl. You can add all the shredded cheese now or save some to sprinkle on top before baking.
Thoroughly mix the ingredients in the bowl to evenly coat the pasta.
Transfer the mac and cheese mixture to a baking dish. Top the baking dish with the optional remaining shredded cheese.
Bake the mac and cheese in a preheated oven at 350°F (175°C) for 10-12 minutes, or until warmed through and bubbly. Once done, carefully remove it from the oven, serve this mac and cheese warm, and enjoy!
