How to make Perfect Olive Garden Alfredo Sauce
It’s fitting that white Alfredo sauce — an American invention — is one of the most popular dishes at the quintessential American Italian restaurant. Scoff all you want, but Olive Garden’s Alfredo sauce is delicious and addictive. It’s also incredibly easy to make — even though you might be trying a few cooking steps you haven’t done before. Olive Garden’s Alfredo sauce is a great beginners course into the wonderful world of pan sauces, and one you can undoubtedly create at home.
Gather Your Ingredients
Here’s what you need to make your own Olive Garden Alfredo sauce: Butter, garlic, flour, milk, heavy cream, Parmesan cheese, and Romano cheese. And that’s it! The full ingredients list is at the end of this article, along with a step-by-step recipe.
What are we getting into?
So, what’s the deal with Olive Garden’s Alfredo? The flavor is more garlic and butter than cream — but that’s not exactly a bad thing. It’s a bit thicker than you think, and sticks well to pasta. It’s really the butter that gives it the savory taste, but there are actually a lot of flavors going on — which is why the idea of the Alfredo seems complicated when it’s actually not.
You need a lot of Butter
As I mentioned before, a traditional Italian Alfredo is nothing like what we know and love today. The original Italian Alfredo was simply butter and Parmesan — and you’d end up with a nutty, buttery, and not especially thick sauce. Butter still plays heavily into the American Alfredo, so we’ll need 3 ounces of butter. As I often suggest, feel free to useunsalted butter, because the end dish will have a ton of salt in it from all the cheese anyway.
We’re using the Real Garlic
Powdered garlic is more of a flavor enhancer, but fresh garlic brings the flavor — which is why we’re using it here. We’ll need about a tablespoon of garlic, which is roughly one garlic clove.
If you don’t know the magic trick to getting garlic peeled easily, here’s the gist. As pictured above, lay a large flat knife on the garlic clove and press down firmly on the side of the blade to “crush” the garlic — only you’re not literally crushing the garlic, but simply putting enough force to crack the skin. After that, it will peel right off, and from there you can finely mince the garlic.
If you’re tempted to just buy some pre-minced garlic, don’t. Why? Well, there are a plethora of reasons, but the main ones we’ll focus on is the brine will sap away a lot of the garlic flavor. Plus, it’s a lot cheaper to buy a clove and do it yourself.
You’ll Need a Thickener
In order to make any sauce, you need to thicken it up. The easiest way is to add flour to a fat. We’ll need two tablespoons of flour — the basic formula is equal parts flour and fat, but this recipe has a little more fat in the form of butter, for flavor. The end dish needs to maintain some butter flavor, so it’ll be fine.
If you have a gluten issue, or just want to keep your gluten count down a bit, feel free to substitute gluten-free flour in here; it’ll work just fine.
Skip the Skim
Alfredo sauce is white. Milk is white. Seems like a no-brainer. This is the base — the dairy and the coloring comes from our good friend the cow. We’ll need 1 ½ cups. Use whole milk, none of that skim stuff.
Add the Cream
The heavy cream will bring a bit more volume than good old milk. There are subtle differences between heavy cream and heavy whipping cream — the latter is much easier to find at your local grocery store. The reality is that regardless of the word “whipping,” they both contain enough air to make the white stuff thicker, and that’s what we want for the final Alfredo sauce — volume. We’ll need 1 ½ cups of heavy cream.
Next add the cheeses. Add the Parmesan and Romano, then break out a whisk and give that cheese a nice twirl or 30. Just keep working the cheese until it starts to break down — it doesn’t have to be completely gone but let’s at least help it get where it needs to be.
A little Garnish
Why do we put parsley on our dishes? Is it so they look pretty? Originally, the leaf was a palate cleanser after a meal. Today, it’s that thing you pluck out of the middle of your food and put it as far away from your eating area as possible. So can you eat it? You bet you can. Parsley goes great with pasta, so instead of tossing it off to the side, take that parsley and eat it. Olive Garden actually cuts up their parsley so it looks nice and pretty on the plate — that contrast of green on white. I kinda like the traditional way of just sticking a leaf in the middle. You can eat it either way.
How close are we?
There are three flavors you pick up immediately; the nutty flavor of the Parmesan cheese, the garlic, and the butter. And remarkably, this tastes just like Olive Garden’s Alfredo. If you look at the images, besides the obvious difference in pasta (I went with gluten-free spaghetti), the sauce looks the same. Olive Garden really piled it on in that photo — I was a bit more delicate with the portion.
You can add salt and pepper to taste, but you don’t need any salt at all. This thing is already clocking in at somewhere close to 25 percent of your daily recommended allowance of sodium — give or take a bit — and adding salt will make this Dead Sea-like in salinity.
If you can make this Alfredo sauce you can make any sauce out there. They all need a roux, they all add liquid, and they all thicken. Just swap out the milk for Marsala and you’ve got a great steak sauce. White wine and it’s excellent on chicken. All the steps are right there, now go make a sauce or two!
