Begin by cooking the pasta. In a large pot, boil salted water and add the pasta. Cook according to package instructions until al dente. Reserve ½ cup of pasta water and then drain the rest.
While the pasta is cooking, heat olive oil in a saucepan over medium heat. Add the minced garlic and sauté for about 1-2 minutes until fragrant, but do not let it brown.
In a mixing bowl, combine the cottage cheese, vegetable or chicken broth, cooked garlic, salt, black pepper, and red pepper flakes (if using).
Blend the mixture using a blender or food processor until smooth and creamy.
Return the drained pasta to the pot and add the cottage cheese sauce. Toss well to combine, adding reserved pasta water as needed to reach your desired sauce consistency.
Stir in the grated Parmesan cheese until well incorporated. Adjust seasoning to taste.
Serve immediately, garnished with fresh basil leaves if desired.
