While the squash roasts, heat olive oil up in your dutch oven over medium-high heat. Add the bacon and cook, stirring, until browned and fat is rendered, 4 to 5 minutes. Add the onions, carrots, celery, and garlic and cook until soft, 4 to 5 minutes.
Add ground venison, and cook, stirring, until no longer pink, about 5 minutes. Add in bay leaves, thyme, oregeno, cinnamon, nutmeg, salt and pepper. Cook for 1 minute to toast the spices. Add the tomato paste and cook for another 1-2 minutes.
Pour in beef broth, marinara sauce, and coconut milk. Bring to a boil while stirring occasionally, then lower the heat and simmer for 10 minutes to thicken the sauce.
Discard the bay leaves and season with salt and pepper too taste.
Use a fork to scrape the spaghetti strands from the squash and place in a serving bowl. Serve topped with Ragu sauce and garnish with fresh chopped parsley.
