I love spaghetti squash because it’s a great low-carb option. You can find it at most grocery stores. Olive oil adds richness and helps cook the veggies nicely. Use fresh vegetables for the best taste and texture. Onions and garlic give a strong base flavor. Carrots, celery, bell peppers, and zucchini add sweetness and crunch. Each bite is a burst of flavor.

The sauce is the heart of this dish. Crushed tomatoes make a tasty base, while tomato paste thickens it up. Oregano and basil bring classic Italian flavors. If you want heat, add red pepper flakes. Don’t forget salt and pepper to enhance all of this goodness.
Garnishes

Garnishes make your dish pop! Fresh basil adds a bright taste and a nice look. Grated Parmesan cheese is a tasty and creamy finish. These touches make the dish feel special.

Step-by-Step Instructions
Preparing the Spaghetti Squash
Preheating the oven and cutting the squash First, turn your oven to 400°F (200°C). This will help cook the squash evenly. Then, take your medium-sized spaghetti squash and carefully cut it in half lengthwise. Use a spoon to scoop out the seeds.
Drizzling oil and seasoning Now, drizzle a bit of olive oil inside each half. Sprinkle some salt and pepper to season it. Place the squash cut side down on a baking sheet lined with parchment paper. This makes for easy cleanup later.
Making the Bolognese Sauce
Sautéing the vegetables While the squash roasts, heat a tablespoon of olive oil in a large skillet over medium heat. Add the chopped onion, minced garlic, diced carrot, diced celery, and diced bell pepper. Sauté these for 5 to 7 minutes until they become tender and smell great.
Adding tomatoes and spices Next, stir in the diced zucchini and cook for 3 to 4 minutes. Then, pour in the crushed tomatoes and tomato paste. Add your dried oregano, dried basil, and red pepper flakes if you want a little heat. Mix everything well. Reduce the heat and let the sauce simmer for 15 to 20 minutes. Stir it occasionally and season with salt and pepper to taste.
Combining and Serving
Shredding the squash When the spaghetti squash is cooked, let it cool a bit. Use a fork to scrape the inside, creating spaghetti-like strands. Place these strands in a large bowl.
Topping with sauce and garnishing Generously pour your Bolognese sauce over the squash strands. For a nice touch, garnish with torn fresh basil leaves. If you like, sprinkle some grated Parmesan cheese on top for added flavor. Enjoy your meal!
Tips & Tricks
Cooking Tips
- Perfect roasting time: Roast the spaghetti squash for 30 to 40 minutes. Check for tenderness. It should easily shred with a fork.

Common Mistakes to Avoid

- Make It Ahead: The Bolognese sauce can be made in advance and stored in the refrigerator for up to three days, making meal prep a breeze.
