Place the cottage cheese, parmesan cheese, milk, oregano, salt, and black pepper into a high-speed blender.
Process the mixture on high until the texture is completely smooth and no curds remain.
Heat olive oil in a large skillet over medium-low heat and sauté the minced garlic for approximately 1 minute until fragrant.
Reduce heat to low and pour the blended cheese mixture into the skillet.
Whisk or stir the sauce continuously for 2-3 minutes until heated through, ensuring the sauce does not reach a boil to prevent curdling.
Immediately toss with hot cooked pasta, adding a splash of pasta water if a thinner consistency is desired.
