Make a lengthwise outline around the squash with a small, sharp paring knife. Pierce the knife in multiple places on the outline. Continue making small slices around the squash until you can easily pull it apart.
Scoop seeds out of each half.
Brush each half with olive oil and sprinkle with salt.
Bake for 45 minutes, or until edges are slightly burned.
Let cool for at least 20 minutes then shred into noodles using a fork.
Mushroom Soup
While noodles are cooling, heat oil in a large pot over medium-high heat. Add garlic and shallots, stirring occasionally, until fragrant (~2-3 minutes).
Add mushrooms and cook down until they've turned a deep golden brown (~15 minutes). Stir every few minutes and wait until they've released their liquid.
Add water, coconut aminos, vinegar, cilantro, parsley & salt. Simmer for 15 minutes, until flavors have combined. Add cooked spaghetti squash noodles and simmer for another 3-5 minutes. Serve immediately.
Notes
Make sure to completely cook the mushrooms down so they have released all liquid and are a golden brown color. The flavor can't be beaten.
Prepare the noodles ahead of time for an easier weeknight meal.
