How to Make Alfredo Sauce
Making this 3-ingredient Alfredo sauce is so ridiculously easy, you’ll wonder why you ever bothered with anything else—just melt, mix, and indulge in creamy perfection!
- Grate the Parmesan cheese.
- Heat a saucepan to medium and add the stick of butter to the pan.
- Stir occasionally while the butter is melting. Once the butter is melted, add cream and whisk. Allow the cream/butter mixture to come to a boil slowly. Watch out, once the boiling point is reached this mixture will overflow your pan quickly!
- Once the cream starts to bubble, take the pan off the heat and whisk in the Parmesan cheese until melted and combined. Add salt and pepper to taste. Voila!!! Serve and enjoy.
Hint: This sauce is best enjoyed immediately, but I have had success keeping it on a very low burner and whisking every couple of minutes if the rest of my dinner needs a little more time.
Substitutions
With such a short list of ingredients, every one of them is absolutely necessary to create Alfredo perfection. There is no room to fake it here--get yourself the right ingredients if you want to reap the reward of THE BEST SAUCE YOU'VE EVER HAD.
Variations
This decadent Alfredo sauce is amazing as is, but feel free to tweak it to your taste. Here are some ideas:
- Garlic: Add minced garlic or garlic powder for that savory punch. You can sauté fresh garlic in the butter for extra flavor.
- Lemon: A squeeze of lemon juice or a zest adds a refreshing, bright contrast to the creamy richness.
- Spices: A pinch of nutmeg or red pepper flakes can bring a subtle warmth or spice to the sauce.
Equipment
You'll need a saucepan, cheese grater, and whisk. That's it.
Storage and Reheating
I would recommend eating this sauce immediately (and if you're anything like me you'll be licking the plate), but if you do have leftovers they can be stored in an airtight container in the fridge for 2-3 days. The texture will never be as perfect as freshly made, but I've had success reheating the sauce over a low heat, whisking to recombine anything that has separated during refrigeration, and adding small amounts of heavy cream if the sauce is too thick. If I just want a quick Alfredo snack (no judgement here), I've also thrown the refrigerated sauce directly onto leftover pasta and nuked everything in the microwave for a minute.
What kind of Parmesan cheese should I use for Alfredo sauce?
Okay, listen up — if you’re going to make this Alfredo sauce perfect, you absolutely need to use freshly grated Parmesan. I’m talking about the good stuff you buy in a wedge, not the pre-grated green can (I'm not a green can hater, just not for this recipe!). Please don't be tempted to buy anything but the wedge; even the real Parmesan that comes pre-shredded is treated with non-caking agents to keep it from clumping, and it will NOT melt properly in this sauce. The difference is real, people! Freshly grated Parmesan melts into the sauce like a dream, giving it that smooth, velvety texture we all crave. Plus, it adds so much more flavor—sharp, nutty, and super decadent. Trust me, you deserve it. So get yourself a wedge, grab your grater, and let that cheese work its magic. You’ll never go back.
FAQ
The secret here is freshly grated Parmesan cheese. Get the real Parmesan in the wedge--not the powdered green can or even the pre-shredded Parmesan. Neither of those will melt properly into the sauce. Grate the Parmesan directly before making the sauce and it will be fresh and ready to melt into a creamy, dreamy sauce.
A splash of fresh lemon juice adds a burst of acidity that balances the richness of the sauce. Sautéing fresh minced garlic in the butter before adding the cream adds a rich, savory flavor that enhances the sauce. Add a pinch of cayenne pepper or red pepper flakes to introduce a bit of heat. Freshly cracked black pepper will intensify the flavor and give a subtle spiciness.
