Method
Heat avocado oil in a large pot on the stovetop over medium heat.
Add red onion and cook, without stirring, for about 3-4 minutes. Then, stir occasionally until onions are slightly brown and caramelized.
To the pot, add garlic and stir for one minute.
Next, add broth, squash, nutritional yeast, coconut aminos, lemon juice, salt, thyme, and pepper. Stir.
Reduce heat to low and let slow simmer for about 10 minutes, stirring a few times.
Stir in cashew milk, turn the heat off, and let mixture cool.
Using an immersion blender (or food processor or powerful blender), mix everything together until it’s well combined and becomes completely smooth.
Cook pasta according to package directions.
Stir together sauce and pasta in a large bowl. Garnish with chopped fresh parsley. Serve immediately and enjoy!
