Homemade Alfredo Sauce recipe – the best pasta sauce made with half and half, Parmesan cheese, garlic and butter. Perfect sauce with fettuccine pasta, chicken or white pizza!
Use this pasta sauce to serve with fettuccine, like my Bacon Mushroom Chicken Alfredo or my Cheesy Chicken Alfredo Pasta Bake.
One of the most popular pasta sauces happens to be super easy to make completely from scratch right in my own kitchen. You can make it right before serving or ahead of time and store in the fridge. Add pasta of your choice, vegetables, meat and you have dinner on the table in under 30 minutes.
If there is one from-scratch recipe that you try this week, it has to be this one! It will make you fall in love with cooking at home and cooking from scratch.  I make this sauce every week and serve with fettuccine, chicken, bacon (and sometimes ham) for a decadent pasta dinner OR mix with penne, broccoli and mozzarella and bake to perfection.
Ingredients
- butter
- garlic
- half and half
- Parmesan cheese
- cornstarch
- Italian seasoning
- dried oregano
- salt and pepper
Instructions
- Melt butter in a saucepan. Add garlic and cook until golden and fragrant.
-
Whisk together half and half, cornstarch, salt, pepper, Italian seasoning and oregano. Add to garlic. Cook, stirring often until thick. Add Parmesan cheese and stir it in to melt.
-
Remove from heat and use immediately OR cool completely and store in the fridge for up to 3 days.
Storing and freezing
You can store homemade Alfredo sauce in a jar with lid for up to 6 days.
Yes, you can freeze Alfredo sauce. After cooking, cool the sauce completely. Place in freezer-safe bags or containers, date and name it and store in the freezer for up to 6 months. When ready to use, reheat over medium-low heat, stirring constantly. Often times, frozen creamy sauces tend to curdle, so stirring it over lower heat is essential.
Canning
While you can find recipes for canned Alfredo sauce, it is not recommended to can dairy sauces. Besides, this recipe is quick and easy to make ahead of time, up to 6 days.
Expert tips
- cornstarch: I’ve been experimenting with this sauce recipe for years and finally settled on the perfect amount of garlic and Parmesan cheese that makes this sauce. I stopped using flour in my sauces years ago, when I learned that cornstarch never clumps and creates the smoothest textures. I highly recommend trying it.
- garlic: I always saute garlic in butter for this recipe but if you want to skip this step, you can add all of the ingredients into a blender, blend for 20 seconds until smooth and add to chicken in a saucepan and cook until it thickens. If you don’t have fresh garlic on hand, use 2 teaspoons of garlic powder. If you have any questions, please leave them in the comment section below and I will be happy to answer them! 😀
- Parmesan: try to avoid pre-shredded Parmesan cheese as it is often coated with starch to prevent sticking. I highly recommend buying Parmesan cheese in wedges and grating it at home.

Flavor was good! I did find that 2 tbsp of thickener was too much though, so I added more liquid.
Denise McCarthy says
Made today as I needed a small amount of alfredo to top some beef manicotti. So easy & delicious! Thanks for sharing.

Thank you so much for posting this recipe. The sauce tastes amazing – just like restaurant Alfredo. I plan to make chicken Alfredo calzones – pretty sure they’ll be a big hit! Looking forward to checking out your other recipes 🙂
Anna says
That’s fantastic! I am so glad it was a hit!
Rhonda says
This is easy and very delicious! I recommend this sauce.
I did add onion powder and 1 oz. of cream cheese and salad shrimp to go with Farfalle pasta.
Next time I would try adding small bacon pieces or mushrooms peices and cut in half spinch leaves.
Anna says
Thank you so much, Rhonda! I am so glad you like the sauce. I love the idea of adding bacon and veggies!

Hi. At the beginning of the article you say it can be stored in a jar with a lid for up to six days and then at the end of the recipe you say only three days. Which one is it? I’m hoping it’s the 6 days!

We love alfredo sauce here! I actually made one from scratch this week and used bacon grease instead of butter and chopped up the crispy bacon and tossed it in with the alfredo sauce and chicken. Your sauce looks so thick and creamy and delicious!
