This Roasted Garlic Alfredo Sauce is a rich, creamy and flavor packed concoction perfect for all garlic lovers out there.
Featuring my favorite air fried garlic cloves, this is a total step up over the classic Alfredo sauce.
Roasting garlic brings out its natural sweetness and umami goodness, and when it forms the base of the Alfredo sauce, it transforms this mildly creamy and simple sauce into an absolute flavor bomb.
Plus, it's super easy to make, and is finger licking delicious!

I recently tried a vegan cashew Alfredo sauce recently, and was amazed at how beautiful the flavors turned out.
When making homemade pasta, I love using a creamy sauce, simply because it tastes and feels so elegant. Take my Marry me pasta for example.
And that’s when I thought of lending my classic Alfredo sauce a bit of a twist- with some roasted garlic cloves, and created this genius sauce that I’m regretting not trying out earlier.

What's So Great About the Recipe?
The flavor profile of this creamy roasted garlic sauce is insane.
The char and slight smokiness of the garlic really compliments the classic cream sauce and takes it to the next level.
You’re gonna love using it for all of your favorite recipes, and if you love a good chicken Alfredo pasta, you’ll use this version of the recipe every single time- it is a promise!
Ingredients For the Roasted Garlic Alfredo Sauce Recipe
To make this homemade roasted garlic sauce, here’s what you’ll need.

Garlic: Roasted garlic makes everything better, and it is quite literally the hero ingredient here. You’ll need a whole head of garlic for this recipe.
Butter: I used salted butter, but you could totally use unsalted butter if you want to.
All purpose flour: I used AP flour to make the roux for the sauce.
Milk: A dash of milk helps loosen up the sauce and gets it to the perfect consistency.
Cream: I used heavy cream to lend the Alfredo sauce some extra creaminess. You can also use low fat cream.
Cheese: You can use any kind of cheese to add a bit of saltiness and depth of flavor to the sauce. I used shredded cheddar cheese, but you can also use some freshly grated Parmesan cheese if you want to.
Oregano: I used dried oregano, but you could also add any other dried herb of your choice. In fact, I think you could also use some Italian seasoning or my homemade garlic bread seasoning if you want an extra layer of flavor.
Seasonings: I kept the seasonings simple and just used some salt and black pepper

How to Store Leftover Alfredo Sauce
The best way to store your leftover Alfredo sauce is to transfer it to an airtight container and refrigerate it for up to a week.
If you want the sauce to last longer, you can freeze it too. Just make sure you use a freezer bag or a freezer safe container to keep away the freezer burn.

Remember that the consistency of the sauce will thicken up as it cools down, but it should loosen up as you warm it up. If you still want the sauce to be thinner, you can add a dash of milk into it while you’re reheating it.
I would recommend reheating the leftover sauce in the microwave, stirring it at every 20 second interval.
You can also reheat it in a saucepan over the stove top if you want to. Just make sure you do it on low heat to keep it from burning.
