Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the pasta and cook until al dente according to the package instructions. Drain and set aside.

Step 2: Blend the Cottage Cheese Sauce

In a high-speed blender or food processor, combine the cottage cheese, milk, garlic powder, onion powder, salt, and pepper. Blend until smooth and creamy.

Step 3: Heat the Sauce

Transfer the blended sauce to a large saucepan over medium heat. Stir gently and bring it to a light simmer. Add in the shredded cheddar cheese and stir until melted and fully incorporated.

Step 4: Combine Pasta and Sauce

Add the cooked pasta to the saucepan and gently fold it into the cheesy mixture until everything is evenly coated. Add butter if desired for extra richness.

Step 5: Serve or Bake

Serve immediately for a creamy stovetop version, or transfer to a baking dish, sprinkle with Parmesan, and bake at 375°F (190°C) for 15 minutes for a crispy top.
