My Semi-Homemade Alfredo Sauce Recipe (2024)

FAQs

Why did my homemade Alfredo sauce separate? ›

This happens when there's too much fat or liquid in the mixture. This can happen when there are not enough emulsifiers (which help keep your ingredients together). Sauces are usually made from multiple ingredients that include both oil and water. Oils and water will naturally separate.

The key ingredient in Alfredo sauce is cheese—generally Parmigiano Reggiano—and lots of it. To thicken Alfredo sauce, simply add more cheese than the amount called for in a recipe until you achieve the consistency you want.

Try a simple mix of chopped chicken, carrots, and sliced Cayenne pepper, or add ground beef browned with onions. Some people also add fresh broccoli, but that's not among my personal favorites. Seasonings, spices, and fresh herbs: this is definitely a great way to give your Alfredo sauce a more personal flavor.

Fresh parmesan cheese grated off the block is one of those key ingredients. This will create a smooth textured sauce rather than a grainy one. Butter: Both unsalted or salted work for this alfredo sauce recipe. If using salted butter, then just adjust the extra salt you use or omit it entirely.

The Fix Is Simple—Add Water Back.

Here's how fix a broken sauce: Add about ¼ cup of water to the pan and reheat the sauce to a vigorous simmer, whisking constantly. The bubbling action will help re-emulsify the butter and bring back that thick, glossy sauce.

Your fat and water are separating. Adding the hot pasta water should help bring it back together.

Bring the butter-cream mixture to a boil, then reduce the heat and simmer gently, uncovered about 3 to 5 minutes. Cook the sauce gently until it begins to thicken, stirring frequently with a wooden spoon. You'll know the Alfredo sauce recipe is thick enough when it coats the back of your spoon.

After 12 ounces of fettuccine pasta noodles are finished cooking, reserve 2 cups of the pasta water to include in your sauce. The starchy water is essential to creating a thick, creamy sauce consistency.

Flours can be used to make a bit of a slurry and add to the sauce to make it thicker. 1 part flour to 2 parts liquid and then adding it to your sauce should thicken it nicely. Just make sure that when you make the slurry, there are no lumps in your mixture.

Mix together a little cornstarch in a small bowl with some cold water (or other liquid) until the mixture is smooth to form a slurry. Slowly, whisk the slurry into the simmering sauce in a pan over medium to medium-high heat. Whisk the slurry slowly into the hot sauce until you get the desired thickness.

What is authentic Alfredo made of? ›

Real alfredo sauce is made with 3 simple ingredients: butter, Parmesan cheese and fresh fettuccine pasta. There is absolutely no cream in this dish (cream is common in most American-style alfredo sauce recipes). Make this dish with my fresh homemade pasta, fresh sourdough pasta or store-bought fresh pasta.

If it's still gritty, either it's curdling or you need to use a better cheese. Cheap grated cheese is LOADED with anti-caking agents that make it pour out of the container easily.

It really needs to be sauced as close to service as possible for best results. Starches in the sauce will continue to swell, and gain friends from the pasta. If you just need to thin out a batch you have already made, you could season the milk with recipe seasonings before adding it to thick sauce.

A cheese sauce usually splits because it has been overheated and oil separates from the cheese. Remove it from the heat, add a little cream and whisk it until it is smooth again.

You can try to stir the sauce from time to time while heating, so that the sauces do not separate during heating. You can also try adding some water or stock to the sauce to maintain its consistency. Finally, slow and gentle heating of sauces over low heat can also prevent separation.
