There’s a solid trick I’ll be sure to mention in the recipe below to give you a rich, creamy sauce to pour over your noodles every time. This popular recipe is also keto friendly and gluten-free, so it’s appropriate to serve for even the biggest of gatherings.

Following the instructions for my classic Alfredo sauce will yield enough for one pound of pasta, which equates to 2 cups of sauce. As far as noodles go, the wider they are, the better it is because they will really soak in that elegant Alfredo sauce, but I like to switch it up and use spaghetti noodles. Feel free to use the pasta of your choice, of course– fettuccine noodles and penne pasta are popular choices!

Tips For The Best Alfredo Sauce

Making something as useful and flavorful as authentic alfredo sauce to make this recipe for chicken alfredo requires patience, as you’re not going to want to boil or overcook this elegant sauce.

Always use a whisk instead of a spatula and add your dairy ingredients slowly over a low heat to avoid any separation and clumping. Doing this also helps to create an even thickness and enhance the flavor of this delicious recipe that you’ll certainly want to keep in the dish.

For best results, don’t use powder or pre-shredded parmesan cheese; alternatively, the most classic choice here would be to use one cup of grated cheese from a block of fresh parmesan. Adhere to these easy steps and you’ll get the best Alfredo sauce that’ll give your Alfredo pasta recipe that “wow” factor.

What Other Ingredients Are Added?

Strictly speaking of the Alfredo cream sauce, there’s a few more key ingredients other than parmesan that you’ll want to add that will make for the most creamy Alfredo sauce to throw in any great recipe.

Heavy whipping cream is used over whipping cream, and you’re going to need 2 cups of it.

A majority of the thickness will come from utilizing half a cup of cream cheese cut into small cubes. The last remaining dairy product to add to achieve a silky sauce is a half cup of butter; either salted or unsalted butter will make due.

Furthermore, other main ingredients for my favorite recipe for alfredo sauce are going to include fresh garlic, roughly ½ teaspoon of it to be exact, and it should be minced.

One teaspoon of garlic powder is also called for in this recipe, as well as ¼ teaspoon each of both salt and black pepper.

A whole teaspoon of Italian seasoning will top off this meal and help give you the taste of the essence that comes with each bite when dining at an Italian restaurant.

Once you’ve got your sauce made, everything else falls into place to complete this spaghetti with Alfredo sauce recipe.

Other Ways To Make An Alfredo Sauce

The last time I made this family favorite, I was sure to make multiple servings to store in jars for up to 5 days in the refrigerator, but we were already busting into the weekday stash the very next day because it’s so good, it’s irresistible!

Your jarred variety can be made during the weekend or at the beginning of the week to add to other dinner recipes, like chicken bacon roll-ups or Alfredo pizza. Since the consistency of your Alfredo sauce depends on the type of cream you use, I’ll run through a couple substitutes for heavy cream for you to try next time if you’d like to.

In the mood for a thinner sauce? Whole milk in this recipe certainly makes it a light cream, as there’s less thickness to it than that of an Alfredo sauce made using heavy cream.

Half and half is also fine to use here and can be thickened with approximately 2 teaspoons of flour, but do watch for curdling as half and half contains a low milk fat content.

Dairy-free substitutions are also a good option for making Alfredo sauce and they obtain the authentic Italian pasta taste of any Alfredo when cooking liquid ingredients like lemon juice or veggie broth instead of heavy cream or chicken broth.

I love using Not Chick’N bouillon cubes because they bring out that chicken flavor of your Alfredo sauce dish if that’s your goal.

Nevertheless, for a new take on one of the world’s most beloved cheese sauces, swap the measurement of parmesan for half grated Romano cheese and half grated asiago.

How Long Do I Cook My Noodles?

Soggy or crunchy pasta is a major fumble in the kitchen and can ruin an entire dish no matter how scrumptious the sauce is, but luckily there’s guidelines out there to help you attain al dente for all your pasta dishes.

My favorite paste noodle, spaghetti, typically will cook to perfection in a large pot within 8 to 12 minutes. Fettuccine Alfredo pasta is done in 8 to 13 minutes and the penne noodles finish in 10 to 13 minutes.

Always be sure to salt your water and add the noodles only when the water is boiling. Reserve a little pasta water before straining to add to your dish later for an extra boost of creamy, yummy goodness.

Even though I previously mentioned time approximates for noodles, you’re going to want to time whatever kind of pasta you’ll be working with to be ready around the time your Alfredo sauce will be done. Whether you’re making fettuccine Alfredo or tagliatelle Alfredo, you’re gonna want hot pasta.

Due to the fact that there’s no garlic in an authentic Italian Alfredo sauce, we’ll be making an American-style Alfredo sauce that calls for minced garlic, just to clarify.

How Do I Cook Chicken Breast?

Specifically, I believe the best part of my pasta Alfredo is the moist chicken breast, and I assure they hold their flavor while cooking evenly by first slicing them into thinner cutlets.

  1. After washing and drying the cut breasts, they can be seasoned with salt and pepper; some cooks add a little bit of crushed red pepper flakes for a gorgeous finish on the meat.
  2. Nonstick and cast iron pans are operational to sear the cutlets, but I typically use a stainless steel, large skillet over medium-high heat.
  3. Start by warming a drizzle of olive oil in the skillet and adding the breasts when the pan is hot, not moving them again until a brown crust begins to form that also works as the indicator that they’re ready to flip.
  4. This process that takes 5 to 7 minutes on each side.
  5. Do not remove the chicken off of medium heat until it has reached the safe-to-eat internal temperature of 165 degrees Fahrenheit, or 75 degrees Celsius, and allow the breasts to rest, covered, until you’re ready to slice and serve.

Make The Sauce

  1. Now, take a small saucepan and a little less butter than one tablespoon can hold and melt it. Sauté the minced garlic in the melted butter, stirring frequently, until fragrant, so about four minutes.
  2. To fire up that creamy white sauce in a medium saucepan over medium heat, add heavy cream, butter, and the cream cheese, whisking until melted. This will give you a thicker sauce.
  3. Add minced garlic, garlic powder, salt, pepper, and Italian seasoning and continue whisking until the mixture becomes smooth.
  4. Taking one minute to gently whisk in the grated Parmesan cheese will do so much for your dish! Taking the pan off the heated burner to stir in the cheese isn’t unheard of either.
  5. As soon as you’ve got your cheese melted, it’s a good time to drop your pasta! Into boiling water the noodles go, and while your pasta cooks, begin the next step.
  6. Return the pan containing the Alfredo sauce to heat and simmer until your sauce begins to thicken; if this is your first time, you’ll want to wait 5 to 10 minutes and be whisking continuously. Don’t forget to reserve some of that pasta cooking water when you strain your noodles!
  7. Toss the sauce with your spaghetti noodles and serve with your sliced chicken breast! Add a teaspoon of pasta water to the pan and stir, adding one teaspoon increments until you’ve reached a desired consistency, then enjoy!
