I’m honestly a little embarrassed to admit this.
A few months ago, while chatting with Gianna and Chuck on Slack, I realized something surprising: I had never tasted Alfredo sauce. Not even once.
At first, I didn’t think it was a big deal. I knew what it was and had read about it, but I’d never been curious enough to try it. After all, none of my relatives or close friends used it, and I never heard people in my town talk about it.
And then it hit me—how weird is that?
Rome is only a three-hour drive from here, yet it’s almost like this sauce doesn’t exist for us. And I don’t think it’s just a regional thing.
Sure, Italy’s major food blogs cover it, but my impression is that, aside from cuisine enthusiasts, most everyday people barely know it. Some might not even consider it a native Italian recipe.
And that’s wild, considering it was created in our capital city decades before Carbonara—a dish we debate online and in real life all the time.
In a way, we’re quietly overlooking a world-famous Roman recipe simply out of disinterest.
With that new perspective, I couldn’t keep ignoring it. So I asked Chuck what recipe he uses at Mortadella Head and did some research to better understand it—including practical tips like how to thicken up alfredo sauce when the texture isn’t quite right.
This article is for both you and me. We’ll look at two ways to make Alfredo sauce from scratch, how to fix and improve it, how to make store-bought versions better, and how to store it properly.
Here’s everything we should know about this creamy white sauce.
A Bit of History
Alfredo sauce is a pasta dressing derived from fettuccine Alfredo, a dish created in Rome by chef Alfredo di Lelio.
If we want to be picky, it seems that the use of dressing fettuccine with an emulsion of butter and parmesan cheese (oops, spoiler) was a centuries-old Roman tradition that had been lost during history. However, Alfredo deserves credit for bringing it back to life and making it famous.
Legend has it that he created the first fettuccine Alfredo to provide nourishment for his wife, who was expecting a baby and had lost her appetite.
This was confirmed by Ines di Lelio, Alfredo’s granddaughter, who told Mortadella Head the full story some time ago. We transcribed it in our post “Easy Meatballs & Alfredo Sauce.“
Later on, an American customer liked Alfredo’s fettuccine so much that he begged him to include it as a regular course on his menu.
With time and word of mouth, Alfredo’s restaurant became famous among American tourists passing through Rome. This culminated in 1927 with the visit of famous actors Mary Pickford and Douglas Fairbanks, who gave Alfredo a golden fork and spoon in gratitude for his hospitality.
Now, the sauce used to season fettuccine Alfredo has become a recipe in its own right. It often involves some extra ingredients and can be used to make so many dishes! Not only pasta but also appetizers, white pizza, sandwiches, and some meat dishes.
If you’re curious about how to thicken Alfredo sauce for these versatile dishes, let’s dive deeper into the process and techniques.
How the Original Alfredo Sauce Was Made
The traditional Alfredo sauce, created by Mr. di Lelio, was incredibly simple: ½ lb of butter and ½ lb of grated Parmesan cheese. Here’s the full recipe:
- Boil 1 lb of fettuccine pasta in salted water until al dente.
- Melt butter in a non-stick skillet or saucepan.
- Add Parmesan cheese and stir gently to create a creamy consistency.
While the original recipe has evolved over time, it remains a timeless classic.
How to Thicken Alfredo Sauce
Thickening Alfredo sauce can take it from ordinary to extraordinary. Here are tried-and-true methods to achieve the perfect texture:
1. Add More Cheese
Parmesan or cream cheese works wonders for thickening. Stir grated cheese into the sauce over medium heat until fully incorporated.
2. Use Cornstarch or Arrowroot
Mix cornstarch with cold water to create a slurry. Add this to your simmering sauce while stirring constantly for a smooth, thick consistency.
3. Incorporate Egg Yolks
Whisking in tempered egg yolks adds a rich, custard-like thickness. Be sure to temper the yolks by adding a bit of warm sauce first to avoid curdling.
4. Use Pasta Water
Cook the pasta in the sauce with 2–3 ladles of pasta water. The starch in the water binds with the dairy to naturally thicken the sauce while enhancing its flavor.
How to Make Jarred Alfredo Sauce Better
If you’re using a store-bought jar of Alfredo sauce, here are ways to improve its flavor and texture:
- Add Dairy: Incorporate heavy cream, sour cream, or even milk for extra creaminess.
- Enhance with Broth: Add chicken broth for a richer flavor and let it reduce slightly.
- Include Vegetables or Proteins: Try steamed broccoli, grilled chicken, or sautéed shrimp for a heartier meal.
- Experiment with Seasonings: Use garlic, black pepper, or fresh herbs like parsley to elevate the flavor.
Alfredo Sauce Expert Tips
- Use High-Quality Parmesan: Parmigiano-Reggiano provides a richer flavor.
- Cook Low and Slow: Prevent curdling by cooking over low heat and stirring constantly.
- Save Pasta Water: Reserve starchy water to thin or adjust the sauce’s consistency.
- Season Last: Parmesan adds saltiness, so taste before adding extra salt.
Troubleshooting Common Alfredo Sauce Mistakes
Why Is My Alfredo Sauce Grainy?
This happens when cheese is added at high heat. Always stir cheese into the sauce over low heat to prevent curdling.
Why Did My Sauce Separate?
Overheating or adding cream too quickly can cause separation. Stir constantly and keep the heat low.
How to Fix Thick Sauce
If the sauce is too thick, add reserved pasta water, milk, or cream in small amounts to loosen it up.
How to Store and Reheat Alfredo Sauce
Storage Tips
- Refrigeration: Store Alfredo sauce in an airtight container for up to 3–4 days.
- Freezing: Freeze in a resealable bag for up to 3 months. Thaw slowly in the fridge before reheating.
Reheating Alfredo Sauce
Warm the sauce over low heat, stirring constantly. Add a splash of milk or cream to restore its creamy consistency.
Pair Alfredo sauce with:
- Proteins: Grilled chicken, sautéed shrimp, or baked salmon.
- Veggies: Steamed asparagus, roasted red peppers, or broccoli.
- Breads: Garlic bread, focaccia, or a fresh baguette.
- Salads: Caesar salad or bruschetta to balance the richness.
For a sweet finish, try desserts like tiramisu or fruit sorbet.

Fettuccine Alfredo sauce recipe
Hi Melvin. Our recipe is shown in the paragraph “Mortadella Head’s recipe”.
There is no PARM or SPICES in the ingredients of the recipe at the bottom of the post but the instructions say, “When it starts to bubble, toss in the parmesan and the spices, and mix until you get a nice cream.”
How much Parm & what spices, please? TIA
