Cook the pasta according to package directions and reserve one cup of pasta water. (You will likely only need 1/2 cup but you may want a little extra to thin the sauce.)

In a large saucepan, add the olive oil and garlic and sauté over medium-low heat for 3 minutes.

Add the tomatoes and lemon juice. Simmer over medium-high heat for 10-12 minutes or until most of the juices have evaporated.

In a blender, carefully add the cooked tomatoes, cottage cheese, and 1/2 cup pasta water, and blend until smooth. Be sure to allow steam to escape from the blender if the pasta water and tomatoes are hot. Add an additional splash of pasta water, if needed.

Combine the pasta with the sauce. Season with salt, if needed.
