What You Need for Penne Alfredo

Let’s get into cooking this cozy Alfredo; here’s what to gather up:

Alfredo Sauce with Penne Pasta Ingredients

Ingredients 

These are the basics to gather for your penne Alfredo:

  • Minced garlic: Fresh garlic adds a rich and pungent flavor to the sauce. 
  • Heavy cream: 35% milkfat, a.k.a. whipping cream or double cream.
  • Black pepper and kosher salt: Don’t skip the seasoning – your sauce needs to be well-seasoned.
  • Finely-grated Parmesan cheese: Grate it finely to ensure it melts smoothly into the sauce, creating a creamy texture and adding a savory, nutty taste. While freshly grated cheese is preferred for its flavor and texture, you can substitute it with pre-grated Parmesan cheese if needed. However, the pre-grated cheese may not melt as smoothly into the sauce.
  • Dry penne pasta: Penne pasta works well with Alfredo sauce, as its shape holds the creamy sauce nicely.
  • Minced parsley for garnish: Fresh parsley adds color and freshness to the dish. You can use other fresh herbs if you like. 
  • Butter: For sauteing the garlic.

Substitutions and Variations

This recipe is perfect as is, but here are a few twists and turns you could take with it:

Substitutions

  • Evaporated Milk: If you prefer a lighter sauce, try evaporated milk. It’s thicker than regular milk and less likely to curdle under heat. You can use it as a one-to-one substitute for heavy cream.
  • Garlic powder: If fresh garlic is not on hand, you can substitute it with garlic powder. Use about 1/2 teaspoon of garlic powder for every clove of garlic called for in the recipe.
  • Other pasta shapes: Feel free to use different pasta shapes instead of penne noodles. Fettuccine, linguine, or spaghetti are classic choices for Alfredo sauce.
  • Herby infusion: Infuse other fresh herbs like thyme, fresh basil, oregano or rosemary. You could even use a little italian seasoning, if you like. Simmer the herbs in the sauce for a few minutes to release their aroma before serving.
  • Vegetable additions: Add vegetables like broccoli, spinach, peas, or sun-dried tomatoes. Sauté or steam the vegetables before adding them to the sauce.

Tools to Grab

You’ll need to set aside the following:

  • Large pot: To cook the pasta in.
  • Saucepan: To make the sauce in.
  • Whisk

How to Make Alfredo Sauce with Penne Pasta: An Easy Guide

Here’s a blow-by-blow to the perfect Alfredo sauce with penne pasta:

Cook pasta and melt butter in pan

Cook the pasta

  • Start by cooking the pasta in boiling water with a teaspoon salt until it is al dente. Just follow the package instructions to cook the penne pasta (usually 8-10 minutes).
  • Drain the pasta in a colander.

Make the sauce base 

  • While the pasta is boiling, add the butter to a saucepan and melt it over medium-high heat.
  • Add in the fresh garlic and saute it for about 1 minute. Keep an eye out so it doesn’t overcook. 
  • Lastly, stir in the heavy cream and season with salt and pepper. Simmer gently over a low heat.

Make Ahead and Storage Notes

Want to make this alfredo pasta sauce and pasta in advance and store it? No problem, here’s the story:

Make ahead

  • You can make the Alfredo sauce ahead of time and store it in jars or an airtight container in the refrigerator for up to 2 days.
  • When ready to serve, reheat the Alfredo sauce in a saucepan over low heat until warmed through. You may need to add a splash of milk or cream to loosen the sauce if it has thickened in the refrigerator. Once the sauce is heated, add the cooked penne pasta and toss gently until the pasta is coated and heated through.

Storing Alfredo Sauce with Penne Pasta

  • Leftover Alfredo sauce with penne pasta can be stored in an airtight container in the fridge for up to 3-4 days. 
  • Allow the pasta to cool completely before transferring it to the container. When reheating, you may need to add a little extra cream or milk to the sauce to prevent it from drying out.
  • You can reheat it on the stovetop in a skillet or in the microwave.

While Alfredo sauce can be frozen, it may lose its texture when frozen and reheated.

  • To Freeze: Transfer the cooled Alfredo sauce to a freezer-safe container, leaving some room for expansion, and store it in the freezer for up to 2-3 months.

How to Serve this Alfredo Sauce with Penne Pasta

To lighten the meal a little, serve a crunchy green salad or a strawberry spinach salad with almonds. 

3 Common Mistakes When Making Alfredo Sauce

Steer clear of these issues, here are 5 typical trip ups:

  1. Overcooking the garlic: Guys, this is a no-no. Overcooked garlic will turn your sauce bitter. Make sure to sauté the minced garlic just until fragrant, usually for about 1 minute, being careful not to let it brown.
  2. Boiling the sauce: Adding cheese to a boiling sauce can cause it to clump and become grainy. Remove the saucepan from the heat before adding the cheese, and stir continuously until the cheese is fully melted and the sauce is smooth. Don’t let the sauce boil again once the cheese has been added.
  3. Not seasoning enough: Taste the sauce as you season it, and adjust the amount of salt and pepper. Remember that the Parmesan cheese also adds saltiness, so be cautious not to oversalt.

Final Notes, Pro Tips + Science-Based Secrets

As a food scientist, I’ve got to share my secrets and tips with you:

  • Grate cheese finely: Grate the Parmesan cheese finely to ensure it melts smoothly into the sauce, creating a creamy texture. Pre-grated cheese often contains anti-caking agents that can affect the texture of the sauce.
  • Adjust consistency: If the sauce is too thick, add a splash of pasta water or cream to thin it out. If it seems too thin, let it stand for a few minutes. It thickens right up as it rests a bit.
  • Serve immediately:Alfredo sauce is best served immediately after tossing with the pasta to prevent the sauce from thickening up too much or the pasta from becoming mushy.
  • Cheese melting: Cheese contains proteins and fats that change when heated. When making Alfredo sauce, melting the cheese slowly and gradually over low heat helps prevent it from becoming grainy or stringy.

  6. Emma_T says:

    Looks yummy but gotta find a way to cut down those calories, any ideas?

    1. Jennifer Pallian BSc, RD says:

      You could use evaporated milk in place of the heavy cream! It is more stable than regular milk so it won’t curdle. It also has a thicker, creamier texture.

  7. Gary_N says:

    are you sure about the cheese quantity, seems a lot?

    1. Jennifer Pallian BSc, RD says:

      Oh yes, my friend. Very sure. Enjoy!

  8. Kathy S. says:

    Can i use pre grated cheese for this or is it better to grate it myself? not good with cooking but this seems easy.

    1. Jennifer Pallian BSc, RD says:

      I generally always recommend grating yourself but sometimes I sneak in grated parmigiano reggiano and it’s ok 🙂 Just not the powdery Kraft kind that doesn’t have to be refrigerated.
