Blend the Sauce: Add the cottage cheese, Parmesan cheese, unsalted butter, garlic, salt, and black pepper to a high-speed blender. Process until smooth to create a creamy, alfredo-like sauce that’s simply irresistible.

Boil the Pasta: Bring a large pot of salted water to a rolling boil. Add the linguine and cook until al dente, about 8-10 minutes.

Combine Pasta and Sauce: Drain the linguine but reserve about 1 cup of the starchy cooking liquid. Return the pasta to the pot and stir in the blended Alfredo sauce along with about ½ cup of the reserved pasta water. Set over low heat and cook, stirring constantly for about 3 minutes, until warmed through and slightly thickened.

Serve It Up: Remove from heat and garnish your comforting Cottage Cheese Alfredo Pasta Bake with chopped parsley and extra grated Parmesan cheese if desired. Serve immediately.
