Cook the 8 ounces thin spaghetti in a large pot of salted boiling water until al dente. Drain and set aside.
In a blender, combine the 1 1/2 cups cottage cheese, 1/2 cup milk, and 1/2 cup grated parmesan cheese. Blend until smooth.
Heat 1 tablespoon olive oil in a skillet over medium heat. Add the minced 5-6 garlic cloves and sauté for a few minutes until fragrant, then pour in the blended cottage cheese mixture.
In a small bowl or jug, whisk together the 2 tbsp cornstarch and 4 tbsp water until smooth. Pour the slurry into the sauce and stir well. Simmer for 4-5 minutes until the sauce thickens. If you want your sauce to be extra creamy, you can blend it again for 15 seconds.
Add the cooked spaghetti to the sauce and toss until every strand is evenly coated. Taste and add some Kosher salt and pepper to taste. Serve warm and garnish with parmesan if you like!
Notes
Any type of pasta works - use what you love or what’s in your pantry.
Unsweetened almond, oat, or dairy milk all work in place of regular milk.
Swap parmesan for pecorino romano or nutritional yeast if needed.
Garlic paste can be used instead of fresh garlic in a pinch.
Arrowroot or tapioca starch can be used in place of cornstarch.
If the sauce gets too thick, stir in a bit of pasta water or milk to loosen it.
For extra creaminess, blend the sauce again just before serving.
Add chicken, shrimp, or veggies like broccoli to make it a full meal.
