Preheat the oven to 400 degrees F. Cut the squash in half removing the seeds with a spoon.

Lay squash cut side down on a parchment lined baking sheet. Bake for 20 minutes, remove from oven and let cool for about 10 minutes before using a fork to scrape out the "noodles" from both halves of the squashes.

In a sauté pan over medium-low add the butter and olive oil, then add the minced garlic and sauté until fragrant careful not to burn (about 2 minutes).

Add the spaghetti squash noodles and still together, coating the noodles.

Next stir in both cheeses and salt and pepper. Feel free to add more pepper.

Add spinach and continue stirring until spinach is mostly wilted.

Plate and serve with additional parmesan cheese and black pepper on top.
