Bring a large pot of water to a boil. Add in the Elbow Macaroni and cook until al dente. Drain the water from the pasta and set the pasta aside.
Add to the jar of a blender, the milk, cottage cheese, Greek yogurt corn starch, spices, and grated cheddar. Blend with a stick blender until smooth.
Transfer the cheese sauce to the same pot you boiled the pasta in. Heat the sauce on medium heat, stirring constantly, until it starts to simmer.
Return the cooked macaroni to the pot with the sauce and stir to coat. Stir in the finely chopped fresh dill and serve.
Heat a frying pan on medium heat. Melt the butter in the pan and then add in the panko crumbs. Move the crumbs constantly with a spatula, until golden brown. Remove the toasted crumbs from the pan and use them as a topping for the macaroni.
