How to make Alfredo sauce thinner? ›

The key is to add a little bit of liquid. The most common thinner for any creamy sauce is milk, however, you can also use other liquids like water, broth, or cream. Note that the liquid has to contain moisture so it can actually work, which is why melted butter won't do.

Heartier herbs like thyme or oregano can be added in to simmer with the sauce. Add delicate herbs like parsley, basil, or chervil at the end to maintain their delicate, aromatic flavor. Quick tip: Swirl in a bit of leftover pesto to add another herbaceous twist to your Alfredo sauce.

Use Flour and Water

Combine 2 tablespoons flour with every 1/4 cup cold water and whisk until smooth. Add the mixture to your sauce over medium heat, and continue to stir and cook until you've reached your desired consistency. Test with a spoon.

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.

If you find that your sauce is too thick, this is where you can add some of the reserved pasta water, little dribbles at a time. If you over-water and the sauce becomes too thin, just let some of the liquid cook off and you'll see the sauce thicken up again. It's pretty resilient to fumbles at this stage.

The sauce is too thick

Cause: Ratios are wrong (too much flour) or sauce is cooked too long and too much liquid evaporated. Solution: Whisk more warm milk or stock into the sauce, starting with just a little. Also, add more seasoning if necessary.

Add heavy whipping cream, a little at a time, whisking to smooth out lumps. Stir in Parmesan and pepper. Remove from heat when sauce reaches desired consistency. Sauce will thicken rapidly, thin with milk if cooked too long.

Add starchy pasta water to thin the sauce, if needed. The starch in the water also helps the sauce coat the pasta instead of clumping up or pooling on the plate. I use the pasta cooking water as the base of my alfredo sauce, as done in the recipe below. Pasta water, butter and Parmesan cheese form the sauce.

Use the pasta water to create a creamy Alfredo sauce

This water (which Bon Appetit calls “LIQUID GOLD”) is what emulsifies with the fat in your sauce (oil, butter, cheese, etc) and creates that incredibly smooth sauce. My #1 tip with pasta water is DO NOT ADD IT DIRECTLY FROM THE POT.

Will cream cheese thicken alfredo sauce? ›

Cream Cheese

Keep in mind, it is best to use the full fat version of cream cheese as this melts the best and incorporates into the sauce. You can cut the brick of cream cheese into smaller cubes and then add it to your sauce and it will melt and create a thick cheesy and tangy alfredo.

The Fix Is Simple—Add Water Back.

A generous splash of water is all it takes. 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.

Generally, you'll need 1/4 to 1/2 a cup of alfredo sauce per single serving. Cook the pasta as you would normally. Then, heat your sauce over medium heat and add your pasta in the same pan. Stir and cook the pasta and sauce for 3 minutes.

Extra seasonings and spices will go a long way in adding flavor to a boring jar of sauce. Some of my personal favorites include salt, pepper, Italian seasoning, dried basil, oregano, onion powder or seasoned salt. Start with small amounts (1/2 teaspoon at a time) and add as needed, in order to avoid over-spicing.

Once melted, pour in your jar of sauce. Pour the milk into the jar and give a good shake. Start with 1/4 cup of milk and if more is desired, add another 1/4 cup. Pour the jar into the pan, add in the spices and let simmer on low.

Just add a little bit of heavy cream to that, then place it in the microwave.

Cornstarch: Make a slurry of half water, half cornstarch and whisk until smooth. Cornstarch is a powerful thickener, so start by whisking in no more than 1 tablespoon of the mixture per 2 cups of simmering sauce; stir and simmer for 2 minutes, check the thickness, and repeat with more slurry as needed.
