Let’s get into what you need to make this healthier homemade Alfredo sauce.

Ingredient list

1. Plain Greek yogurt: Plain Greek yogurt is the perfect creamy high protein base for this sauce- it’s a great substitute for heavy cream in a sauce like this because plain yogurt tends to mimic sour cream. I recommend using full-fat Greek yogurt (5%) or your sauce is more likely to break up, and won’t be as creamy or flavorful.
2. Milk: I recommend using 2% or whole milk for this recipe because skim milk or 1% will be a lot less creamy. I like to opt for Fairlife milk because it’s ultra-filtered and a lot creamier than regular milk.
3. Parmesan cheese: You can’t have Alfredo sauce without parmesan cheese! I like to use grated cheese so that it melts into the sauce a little quicker, but you can also use shredded parmesan cheese.
4. Butter: You’ll need just a little of butter for that classic buttery Alfredo flavor- to keep things lighter this sauce uses less than traditional recipes but still has plenty of flavor! If you prefer, you can sub the butter for olive oil.
5. Flour: One tablespoon of flour helps the sauce to thicken up and avoid separating.
6. Spices: You’ll need garlic powder, salt and black pepper to season this easy Alfredo sauce. You can also add fresh garlic or even pre-minced garlic- I like to use garlic powder to keep the sauce smooth and save time.

How to make Greek yogurt Alfredo sauce

1. In a medium saucepan (my favorite!), melt butter on low-medium heat. When butter is melted, add flour and cook for about 2 minutes until bubbly and flour begins to turn golden.
2. Add milk and garlic powder and heat milk for 1-2 minutes, stirring regularly.

3. Remove from heat, then whisk in Greek yogurt ~¼ cup at a time. Once milk and yogurt are smooth, put the pan back on low heat and add the salt and pepper. If needed, you can add a splash of milk or pasta water to thin the sauce.

4. Add parmesan cheese gradually, stirring to melt before adding more. Add any additional salt and pepper to taste.

5. Toss your creamy Alfredo sauce with your favorite noodles, top with more parmesan and fresh parsley if desired and serve with roasted veggies or a side salad.

How to store

Store leftover Greek yogurt sauce in an airtight container in the fridge for up to 4 days. I recommend reheating the sauce slowly in a pan over low-medium heat to minimize the sauce separating.
