My Vegan Take on Trader Joe’s Pumpkin Alfredo Sauce

Every Autumn I see so many people post about the pumpkin alfredo sauce from Trader Joe’s. I tried it once and it’s great, but when I was eating dairy-free a few years ago I needed a vegan option. I tried a lot of Alfredo sauce recipes on the internet, with everything from potatoes to cauliflower in the sauce. None of these sauces ever taste like creamy, cheesy pumpkin Alfredo, though. Well, the secret to vegan cheese sauce is simple, it’s sauerkraut brine! Cheese is fermented, so the secret ingredient for this vegan pasta with pumpkin alfredo sauce makes sense. Here’s what you’ll need to make this delicious vegan Alfredo sauce:

  • Cashews
  • Pumpkin puree
  • Nutritional Yeast
  • Garlic
  • Sauerkraut brine
  • Nutmeg
  • Black Pepper
  • Salt
  • Plant-Based Milk

Vegan Pumpkin Alfredo

This cheesy Alfredo pasta sauce is relatively easy to make! There are two key things I suggest to make this vegan Alfredo sauce perfectly. First, I recommend using a high-speed blender like a Vitamix to ensure the sauce is smooth. Don’t forget to stop the blender and scrape down any pieces stuck to the side. Second, make sure to soak the cashews for a long enough time, and ensure you are using raw cashews. I suggest soaking the cashews overnight in cool water (about 12 hours). If you are in a hurry and want to make this recipe quickly, you can soak the cashews in boiling water for 30 minutes instead.

Vegan Fettuccini Alfredo with Pumpkin Alfredo Sauce

You can use any pasta shape, but I enjoy fettuccini or linguine pasta for this recipe. Pictured here is organic linguine. I think bucatini pasta or rice pasta (if you are GF) would work great here too.
