Creating your Spaghetti Squash Chorizo Bake is a breeze if you follow these simple steps:

1. Preheat the oven: Preheat your oven to 400°F (200°C).
2. Prepare the spaghetti squash: Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle with olive oil, and season with salt and pepper. Place cut-side down on a baking sheet lined with parchment paper.
3. Roast the squash: Roast in the preheated oven for 30-35 minutes, or until tender. Once cooked, set aside to cool slightly, then use a fork to scrape out the strands and place in a large mixing bowl.
4. Cook the chorizo and veggies: In a skillet over medium heat, add the chorizo and cook until browned and fully cooked. Drain excess grease. Add the diced bell peppers and onions to the skillet, sautéing until softened. Stir in the minced garlic, smoked paprika, cumin, salt, and pepper. Cook for an additional 2-3 minutes.
5. Combine ingredients: In the bowl with the spaghetti squash, add the chorizo mixture and marinara sauce. Stir until well combined.
6. Assemble the bake: Transfer the mixture to a greased 9×13 inch baking dish. Spread evenly and top with shredded mozzarella and grated Parmesan cheese.
7. Bake: Place in the oven and bake for 15-20 minutes, or until the cheese is golden and bubbling.
8. Garnish and serve: Once done, remove from the oven and let it cool for a few minutes. Garnish with chopped parsley or basil before serving.

By following these steps, your Spaghetti Squash Chorizo Bake will transform from simple ingredients into a culinary masterpiece.
