How to Make Spaghetti Squash Bolognese

Prepare the Squash: Wash the outside of the spaghetti squash thoroughly. With a sharp knife, carefully slice it in half and scoop out the seeds and stringy flesh inside.
Bake the Squash: Drizzle oil, salt, and pepper on the cut side of the squash. On a baking sheet lined with parchment paper or sprayed with nonstick cooking spray, place the squash cut-side down. Bake at 400°F for 40-45 minutes, until the inside is golden brown and soft.
Extract the Spaghetti: Once baked, let the squash cool for 10-15 minutes. Turn it over, then use a fork to scrape the flesh to create spaghetti-like strands. Transfer these to a bowl and set aside.
Cook the Aromatics: In a skillet over medium heat, add a bit of cooking oil, then toss in the diced onion and minced garlic. Sauté them for about 1-2 minutes until the onion becomes translucent and fragrant.
Brown the Beef: Add the extra lean ground beef to the skillet, using a wooden spoon to break it apart. Cook until browned and no longer pink, which should take around 3-4 minutes.
Incorporate the Vinegar: Pour in the balsamic vinegar and stir well to combine, letting the ingredients meld together for a moment.
Simmer the Sauce: Next, add the drained diced tomatoes, crushed tomatoes, Italian seasoning, sea salt, and ground black pepper. Mix everything together and let it simmer for about 10 minutes, stirring occasionally to prevent sticking.
Combine and Serve: Take the cooked spaghetti squash and mix it with the Bolognese sauce, seasoning with additional salt and pepper to taste. Serve hot and enjoy the delightful flavors of this healthy twist on a classic dish!

Optional: Garnish with fresh basil for a pop of flavor.
