Making this Olive Garden Alfredo sauce

When I say this sauce is ridiculously easy to make, I’m not kidding! All the prep work you need to do is mince the garlic and (perhaps) shred the cheese. Then it’s just a matter of adding the ingredients to the pot at the right time!

This recipe calls for two different kinds of real cheese: Parmesan and Romano. This recipe calls for freshly grated cheese, which is not the dried, powdered kind that comes in a sprinkle can.

You can either buy a block of fresh Parmesan cheese and grate it yourself, or opt for freshly grated Parmesan cheese from the supermarket’s cheese section. Both will work grate (get it?) in this recipe! Romano cheese is less commonly available pre-shredded, so you’ll probably have to start with a block of cheese and grate it yourself.

Cooking this Alfredo sauce

Once you have all your ingredients ready, melt the butter in the pot then stir in the garlic. Add the flour, and cook it till it starts bubbling. This roux will help to thicken the sauce as it cooks.

Once the roux starts bubbling, you can add the salt and pepper, and then both the heavy whipping cream and whole milk, whisking constantly while doing this to prevent lumps.

Then you will bring the sauce to a boil. Don’t forget to keep whisking! Once it’s boiling, you can bring down the heat and cook it for a few minutes. Add the cheeses and mix them in immediately.

Wanna make this meal gluten-free?

Good news! Making this meal gluten-free is so simple! Instead of using all-purpose flour in the sauce, substitute it with an 1:1 gluten-free flour substitute. You can also use organic buckwheat noodles which are naturally gluten-free!
