Warm the olive oil in a deep saucepan over medium heat until it shimmers. Toss in the minced garlic and let it sizzle for about 1-2 minutes until fragrant but not browned. Your kitchen should start smelling amazing right about now.

Sprinkle the cornstarch over the garlic and oil, then stir constantly for a minute. This quick cooking prevents any raw cornstarch taste while creating the thickening base for your sauce.

Pour in the broth and milk in a steady stream while whisking like crazy to avoid any lumps. Once everything's smoothly combined, crank the heat up to medium-high and bring the mixture to a gentle simmer, whisking often.

Let the sauce bubble gently for about 2 minutes, whisking constantly so it doesn't stick to the bottom. You'll notice it starting to thicken up – you want it slightly thinner than the final sauce as we'll be adding more ingredients.

Pull the pan off the heat and little by little, whisk in your blended cottage cheese and Greek yogurt until completely smooth. This off-heat addition prevents the proteins from seizing up and keeps your sauce silky.

Return the pan to medium heat and fold in the Parmesan cheese, salt, pepper, and Italian seasoning. Let the sauce come back to a gentle simmer for about 2 more minutes, whisking frequently, until everything is melted and your sauce is gloriously smooth and coats the back of a spoon.
