Basic Recipe: Ingredients and Instructions
Ingredients
To Make The Spaghetti Squash with Ground Beef Bolognese, you’ll need:
For the Bolognese Sauce:
- 1 lb ground beef (preferably lean)
- 1 tablespoon olive oil
- 1 medium onion, diced
- 2 cloves garlic, minced
- 1 medium carrot, finely chopped
- 1 celery stalk, finely chopped
- 1 can (14 oz) crushed tomatoes
- 1/4 cup tomato paste
- 1/2 cup beef broth (or vegetable broth)
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- Salt and black pepper, to taste
- 1/4 teaspoon red pepper flakes (optional for a bit of heat)
For the Spaghetti Squash:
- 1 medium spaghetti squash
- 1 tablespoon olive oil
- Salt and black pepper, to taste
- Fresh parmesan cheese (optional, for topping)
Instructions
- Prepare the spaghetti squash: Preheat your oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the flesh with olive oil, and season with salt and pepper. Place the squash halves, cut side down, on a baking sheet lined with parchment paper. Roast in the oven for 30-40 minutes or until the flesh is tender and easily shredded with a fork. Once cooked, set aside to cool slightly, then use a fork to scrape out the strands of squash.
- Make the Bolognese sauce: While the squash is roasting, heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the ground beef and cook, breaking it up with a spoon, until browned and fully cooked. Remove any excess fat. Add the diced onion, garlic, carrot, and celery to the pan and sauté for 5-7 minutes until the vegetables are softened.
- Simmer the sauce: Stir in the crushed tomatoes, tomato paste, beef broth, oregano, basil, salt, pepper, and red pepper flakes (if using). Bring the mixture to a simmer, reduce the heat to low, and let it cook for 15-20 minutes, stirring occasionally. The sauce should thicken and develop a rich flavor.
- Assemble the dish: Once the spaghetti squash is ready, fluff the squash strands with a fork. Divide the squash among plates and top with a generous amount of Bolognese sauce. Sprinkle with fresh parmesan cheese if desired.
- Serve and enjoy: Serve hot and enjoy your low-carb, comforting meal of Spaghetti Squash with Ground Beef Bolognese!
Advanced Techniques
1. Slow Cooker Bolognese
For an even richer flavor, you can cook the Bolognese sauce in a slow cooker. Brown the ground beef in a skillet and then transfer it to the slow cooker along with the remaining ingredients for the sauce. Set the slow cooker on low for 4-6 hours or high for 2-3 hours. This will allow the flavors to meld and deepen, creating an even more flavorful sauce.
2. Adding More Veggies to the Sauce
Feel free to add more vegetables to the Bolognese sauce. Mushrooms, bell peppers, zucchini, or spinach are great additions that will not only boost the nutrient content but also add additional flavor and texture to the sauce.
3. Spice it Up
If you enjoy spicy dishes, consider adding a diced jalapeño or extra red pepper flakes to the sauce while it simmers. This will provide a nice heat that complements the savory richness of the beef Bolognese.
