Boil a large pot of salted water and cook the high-protein pasta according to package directions until al dente.
While pasta cooks, place cottage cheese, grated Parmesan, and chicken broth into a high-speed blender.
Process the mixture on high until the texture is completely smooth and aerated.
Heat olive oil in a large skillet over medium-low heat and add minced garlic, sautéing for 60 seconds until fragrant.
Lower the heat to the lowest setting and pour the blended sauce into the skillet.
Season with salt, black pepper, and nutmeg, stirring continuously for 2 to 3 minutes until heated through. Do not allow the sauce to boil to prevent protein separation.
Drain the pasta, reserving 1/4 cup of pasta water.
Toss the pasta directly into the skillet with the sauce, adding reserved water if needed to reach desired consistency.
