This creamy cottage cheese pasta sauce recipe also known as Alfredo sauce delivers all the cheesy and satisfying flavors of classic alfredo while offering a healthier twist.
Blend cottage cheese, parmesan, milk, cornstarch, garlic powder, oregano, basil, salt, and pepper until smooth (1-2 mins).
Heat blended sauce in large pan over medium heat, stirring until thickened (3-5 mins).
Drain pasta, reserve ½ cup pasta water.
Toss pasta with sauce, add reserved water if needed to thin then garnish with parmesan and pepper if desired.
Notes
The sauce will look alarmingly thin when first blended and poured into the pan – resist the urge to add more thickener! It will thicken significantly as it heats up, so trust the process. If you add more flour or cornstarch at this stage, you'll end up with a gluey, overly thick sauce.
Don't skip preheating the pan before adding the sauce – adding the blended mixture to a cold pan can cause uneven cooking and lead to lumps forming. Your pan should be at medium heat before the sauce goes in, and keep stirring frequently as it thickens.
Blend the sauce ingredients until COMPLETELY smooth – any remaining cottage cheese curds will prevent you from achieving that silky alfredo texture. If you spot any lumps after blending, keep going until the mixture is perfectly smooth like heavy cream.
If you want to add even more protein you can use a protein pasta like chickpea or lentil pasta, or grilled chicken breast (about 31g protein per cup) along with a generous sprinkle of parmesan cheese (10g protein per ounce). I also recommend adding some white beans ( 15 g per cup).
