Baked Stuffed Acorn Squash

Baking acorn squash is pretty easy. The hardest part is cutting the raw squash. Make sure you’re using a good, sharp knife and fresh acorn squash.

After cutting, you need to remove the seeds. I like to save squash and pumpkin seeds to bake for snacks.

Before baking, we brush the inside of the squash with olive oil and spices. You can get creative here. I usually use a simple olive oil, garlic, salt, and pepper mixture. Autumn spices like nutmeg can be fun to sprinkle in too.

Vegan Stuffed Acorn Squash

The cheesy Alfredo-like sauce for the vegan mac and cheese is relatively easy to make! There are two key things I suggest to make this vegan cheese 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 if you have the time (about 12 hours). But for the sake of making this recipe quickly, you can soak the cashews in boiling water for 30 minutes instead.

Vegan Stuffed Acorn Squash Thanksgiving Side

You can stuff acorn squash with many different things, but if you ask me, baked acorn squash stuffed with mac and cheese is the best.

The creamy flavor and smooth texture of the cheese pair so well with the nutty flavor of baked squash.

You can use any pasta shape, but I enjoy the traditional elbow macaroni shape in this recipe. Pictured here is Jovial brown rice pasta, but you can use regular wheat pasta too.

  8. In a pot over medium heat, add the oil shallots and garlic. Cook until the garlic starts to brown.
  9. Reduce the heat to low and add the blended sauce to the oil. Stir continuously until the sauce is heated. (You can add a bit more milk if you feel the sauce is too thick).
  10. Add the pasta to the sauce and toss to combine.
