Cut the squash in half, lengthwise. Scrape out the pulp and seeds. (I run a knife all the way around it then scoop it out with a spoon.)
1 medium spaghetti squash
Place the squash flesh side down on a baking sheet for 45 minutes, or until a knife is easily inserted through the outer skin.
Let squash cool for 10 minutes.
Use a fork to scrape the squash out of each half to get the "spaghetti" strands.
Heat a large sauté pan, add the butter and heat over medium-low heat until melted. Then add garlic and cook the garlic for 2-3 minutes, stirring often until fragrant.
2 cloves garlic, 2 tablespoons butter
Add the spaghetti squash strands to the garlic butter sauce and toss well.
Sprinkle the grated parmesan cheese over the top
¼ cup parmesan cheese, Salt and pepper to taste
Notes
Add some protein: Mix in cooked chicken, shrimp, or tofu
Use different cheeses: Substitute Parmesan with Pecorino Romano or Gruyère, feta or goat cheese.
Spicy kick: Add a pinch of red pepper flakes or sriracha sauce for some heat.
Herb twist: Mix in some fresh basil, rosemary, thyme or parsley.
