Bring a large pot of lightly salted water to a boil. Add 2 cups of elbow macaroni (any variety) and cook according to the package directions until just al dente. Drain and set aside.
While the pasta cooks, finely chop ½ white onion, 1 yellow zucchini, and 3 cloves garlic. Heat 1 tablespoon light olive oil in a large skillet over medium heat. Add the onion, zucchini, and garlic and sauté for 5–7 minutes, until softened and fragrant. Remove from the heat.
Add the sautéed vegetables to a blender or food processor along with ⅔ cup cottage cheese, 2 cups shredded cheese, 2 tablespoons butter, 1 cup almond milk, 2 ounces cream cheese, ½ teaspoon paprika, and 1 teaspoon salt. Blend until completely smooth, stopping to scrape down the sides as needed.
Pour the blended cheese sauce over the cooked pasta. Warm everything together over low heat, stirring gently until the pasta is evenly coated and the sauce is heated through. Avoid boiling—gentle heat keeps the sauce smooth and creamy.
