Cook the pasta in a large pot of boiling salt water until al dente. Drain and set aside.
In a blender, combine the cottage cheese, cheddar cheese, milk, cornstarch, and seasonings. Blend until smooth. (I like to use my immersion blender for this).
Pour the cheese sauce into a non-stick pot and cook over medium heat, stirring regularly. Let the sauce gently simmer for about 8 minute, or until it has thickened slightly.
Add the cooked pasta and stir well to coat every piece in creamy, cheesy goodness. Cook for another minute or two to ensure everything is heated through. Season to taste with salt and pepper.
Serve immediately in bowls & enjoy!
Notes
Store & Reheat Properly: Store leftovers in an airtight container in the fridge for up to 3 days. Warm on the stovetop over low heat with a splash of milk or water to restore creaminess, or reheat in the microwave.
