Can I Use Any Type of Spaghetti Squash?

Spaghetti squash can vary in size and shape, but any golden yellow squash will work. Choose one that feels firm and heavy for its size. Avoid green or overly soft ones, as they might be underripe or past their prime. If you’re feeding a crowd, opt for a larger squash or use two smaller ones to ensure everyone gets a generous helping.

Ingredients for the Cheesy Garlic and Herb Spaghetti Squash with Meat Sauce

The beauty of this dish lies in its simplicity. Each ingredient adds flavor, texture, or richness to make every bite satisfying.

Spaghetti squash: This is the star of the dish. Once roasted, its flesh turns into tender, noodle-like strands that soak up all the flavors.
Olive oil: Used to roast the squash and sauté the aromatics. It adds richness and helps caramelize the garlic and onions.
Ground beef: Provides the heartiness and protein for the meat sauce.
Yellow onion: Adds a subtle sweetness and savory depth to the sauce.
Garlic: A must for the robust flavor base.
Crushed tomatoes: Forms the base of the meat sauce, rich and tangy.
Italian seasoning: A mix of herbs that enhances every layer of the dish.
Salt and pepper: To bring balance and round out the flavors.
Fresh basil or parsley: For a burst of color and freshness at the end.
Mozzarella cheese: Melts beautifully over the hot squash and sauce.
Parmesan cheese: Adds a nutty, salty finish.

How To Make the Cheesy Garlic and Herb Spaghetti Squash with Meat Sauce

Step 1: Roast the Squash

Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle with olive oil, season with salt and pepper, and roast cut-side down at 400°F for 35-40 minutes until tender. Once cool enough to handle, use a fork to scrape the flesh into spaghetti-like strands.

Step 2: Prepare the Meat Sauce

In a large skillet, heat olive oil over medium heat. Sauté the diced onion until translucent, then add minced garlic and cook for another minute. Add the ground beef and cook until browned, breaking it up as it cooks. Drain excess fat if needed. Stir in crushed tomatoes, Italian seasoning, salt, and pepper. Simmer for 10-15 minutes.

Step 3: Assemble the Dish

Place the squash strands back into the squash shells or into a baking dish. Spoon the meat sauce generously over the top. Sprinkle with mozzarella and Parmesan cheese.

Step 4: Bake Until Bubbly

Return to the oven and bake at 375°F for 10-15 minutes until the cheese is melted and bubbly. Broil for 2 minutes if you want a golden brown top.

Step 5: Garnish and Serve

Finish with chopped fresh basil or parsley and serve hot.
