Get Your Vegan Comfort Food Fix with this Creamy Vegan Pasta Recipe

There are few foods that check the comfort food box like Fettuccini Alfredo. It’s creamy and carb-y – the perfect food for when the weather is gloomy. One notch above classic Fettuccini Alfredo is Pasta Carbonara, which adds the decadence of eggs and bacon to the perfection of chewy, al dente pasta.

As a plant-based eater, you may have thought that you had to say goodbye to these tasty combinations, but that’s not the case at all. These classic dishes are quite easily and deliciously replicated as vegan-friendly meals with the help of creamy cashew alfredo sauce and vegan pancetta.

How to Make Non-Dairy Alfredo Sauce

Traditional alfredo sauce is a rich combination of butter, heavy whipping cream and parmesan cheese. And while all that dairy may seem hard to substitute, a simple combination of soaked cashews and water, creates the creamy vegan equivalent to a heavy cream sauce.

In lieu of parmesan cheese, a tablespoon of nutritional yeast and fresh lemon juice lend this vegan pasta dish the same notably satisfying tang. Add a little garlic and salt and – Viola! – you have yourself an outstanding creamy cashew alfredo sauce.

What is Pancetta?

When veganizing a recipe, it helps a lot to know what it is you’re looking to substitute with a plant-based ingredient. In the case of this Creamy Cashew Alfredo recipe, I needed to come up with a satisfying pancetta substitute.

If you haven’t come across it before, pancetta is very similar to bacon. It’s pork belly cured with salt and it’s often served in cubes that are pan-fried before being added to a dish. As such, I knew I was after a salty with a hefty dose of creamy fat. And, because my best memories of bacon are of the maple-smoked kind, I wanted to add a little sweetness as well.  

Vegan Pancetta: Mushrooms Make the Best Pancetta Substitute

If you’ve been following my recipes lately, you know that I have access to some pretty interesting mushroom varieties. I’ve had the good fortune of connecting with a local mushroom grower / hunter and they hook me up every week with some really fun mushrooms.

In the past month, I’ve played with King Oyster mushrooms, Chestnut mushrooms, Grey Dove mushrooms, Shiitakes and Lion’s Mane mushrooms. I’ve even taken a crack at cooking Morels and Porcini mushrooms.

As I get a handle on the different tastes, textures and cooking techniques for each variety, I’ve been trying them out in different recipes. For example, a couple of weeks ago I used Lion’s Mane mushrooms to create really tasty, texturely accurate Vegan Crab Cakes.

I was so impressed by the meatiness of the Lion’s Mane mushrooms that I decided to try them out as a pancetta substitute in this Creamy Cashew Alfredo vegan pasta dish. They result was pretty divine.

I know that access to specialty mushrooms isn’t readily available for everyone, so rest assured that this tasty vegan pancetta substitute will work equally well with different mushrooms, like button mushrooms or shiitakes. Chopped Portobello mushrooms would also work very well, I think.

Getting the Maple-Smoked Flavor into Your Vegan Pancetta

Whatever mushroom you decide to work with, you’ll get the bacon flavor from a combination of tamari, maple syrup, balsamic vinegar and smoked paprika. To thicken the sauce, I add a cornstarch slurry. When cooked, this sauce becomes thick and sticky. Add that to the crispy exterior of the mushrooms and you’ve got a really tasty pancetta substitute to work with.

How to Serve this Creamy Cashew Alfredo with Vegan Pancetta and Peas

When serving this dish, I like to time it so that the pasta and peas are hot when they’re tossed together. Given that I only have two hands, I will already have the mushrooms cooked and the cashew alfredo sauce made.

The best way to reheat the cashew alfredo sauce is to re-blend it in a high-speed blender. This keeps it from becoming dry, as it will on the stovetop or in the microwave. After 1-2 minutes in the blender, the cashew alfredo sauce will be creamy and hot and ready to be added to the pasta and peas.

To keep the crispy exterior of the vegan pancetta, I recommend reheating the mushrooms in a skillet. As soon as they’re hot, add them to the pasta and serve it immediately with fresh ground pepper.

Vegan Pancetta

  • ~4 oz Lion's Mane mushrooms wiped clean of dirt and roughly chopped; see Recipe Notes
  • 1/4 cup tamari
  • 2 tbsp pure maple syrup
  • 1 tsp balsamic vinegar
  • 1/2 tsp smoked paprika
  • 1 tbsp cornstarch
  • 1 tbsp water
  • 1 tbsp safflower oil or other high-heat tolerant cooking oil

Creamy Cashew Alfredo Sauce

  • 1 cup cashew pieces soaked in hot water for at least 30 minutes
  • 3/4 cup water
  • 1 tbsp nutritional yeast
  • 1 tbsp fresh lemon juice
  • 1 tsp salt

Pasta & Peas

  • 1 lb fettuccini cooked in accordance with the package directions
  • 1 cup frozen peas defrostedin hot water
  • fresh ground pepper


  • Prepare the sauce for the vegan pancetta by combining the tamari, maple syrup, balsamic vinegar & smoked paprika in a small bowl.
  • Make a cornstarch slurry, by combining the cornstarch and water in a separate bowl. Mix thoroughly and add the slurry to the pancetta marinade.
  • Heat the safflower oil in a large skillet until hot. Add the Lion’s Mane mushrooms and pan fry until golden brown. 2-3 minutes.
  • Add the vegan pancetta sauce and cook on high heat until the sauce is reduced. The mushrooms should be sticky and crispy. Set aside.
  • Add the cooked fettuccini and cooked peas to a large bowl.
  • Combine the soaked cashews,¾ cup water, garlic, nutritional yeast, fresh lemon juice and salt in a high-speed blender and blend until creamy and hot. See Recipe Notes.
  • Add the cashew alfredo sauce to the pasta and peas and gently toss the pasta to coat.
  • Plate the pasta and peas and then top with the vegan pancetta. Season with fresh ground pepper and serve immediately.


  • Lately, I’ve been having a blast trying out new mushroom varietals. I picked Lion’s Mane mushrooms for this recipe because they have a meaty texture, which I thought would be a great pancetta substitute.  Feel free to swap Lion’s Mane mushrooms out for a different variety. I have also tried this with simple buttons mushrooms as well as shiitake mushrooms. Just note that the cook time for a different type of mushroom may vary.
  • The best way to heat up cashew alfredo sauce is to blend it in a high-speed blender. This will make the sauce hot and help to avoid it becoming dried out, as it might in a saucepan and definitely would in the microwave.
  • If you’re not planning on serving this dish immediately, don’t add the cashew alfredo sauce. Wait until just before serving and reheat the cashew alfredo sauce in a high-speed blender and then serve as described in the Directions.
