What Kind of Spaghetti Squash Should I Use?

Look for medium-sized spaghetti squash that feel heavy for their size and have a firm, unblemished skin. Smaller squash may cook faster but won’t yield as much “spaghetti” inside. If you can, pick squash that have a bright, golden hue—a sign they’re ripe and sweet.

Options for Substitutions

There are plenty of ways to make this dish your own:

• Ground Meat: Swap ground beef for turkey, chicken, or even plant-based crumbles for a vegetarian version.
• Cheese: Use a mix of mozzarella and provolone or even add a touch of parmesan for extra umami.
• Herbs: Don’t have fresh parsley? Dried Italian seasoning or fresh basil work wonderfully.
• Tomato Sauce: Use store-bought marinara or homemade sauce with crushed tomatoes, garlic, and herbs.

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

• Spaghetti Squash: This is the star of the dish and serves as the perfect low-carb substitute for pasta. Once roasted, its flesh separates into tender, noodle-like strands that soak up the sauce beautifully.
• Olive Oil: Used for roasting the squash and sautéing the meat. It adds richness and helps carry the garlic and herb flavors.
• Garlic: Infuses the meat sauce with deep, aromatic flavor and enhances the overall taste of the dish.
• Ground Beef: Provides hearty, savory depth to the meat sauce. You can substitute with leaner meats or plant-based alternatives.
• Onion: Adds sweetness and texture to the sauce, complementing the acidity of the tomatoes.
• Crushed Tomatoes or Marinara Sauce: Forms the base of the meat sauce and blends perfectly with garlic, onion, and herbs.
• Italian Seasoning: A balanced mix of herbs like oregano, basil, and thyme that enhances the sauce’s flavor.
• Salt and Pepper: Essential for seasoning both the squash and the sauce.
• Mozzarella Cheese: Melts into a bubbly, golden topping that gives this dish its irresistible cheesy finish.

Step 1: Prepare the Spaghetti Squash

Slice the squash in half lengthwise and scoop out the seeds. Brush the inside with olive oil and season with salt and pepper. Place cut-side down on a baking sheet and roast at 400°F (200°C) for about 35-40 minutes, until the squash is tender and the edges are lightly golden.

---

Step 2: Cook the Meat Sauce

While the squash is roasting, heat a skillet over medium heat. Add olive oil, then sauté diced onion until translucent. Add minced garlic and cook for 30 seconds until fragrant. Stir in the ground beef and cook until browned. Drain excess fat if needed.

---

Step 3: Add Tomatoes and Seasoning

Once the beef is cooked, stir in crushed tomatoes or marinara sauce. Add Italian seasoning, salt, and pepper. Let the sauce simmer for 10-15 minutes, stirring occasionally, to deepen the flavor.

---

Step 4: Scrape the Squash

Once the squash has cooled slightly, use a fork to gently scrape the flesh, creating spaghetti-like strands. Leave the strands inside the shell to form a natural bowl.

---

Step 5: Assemble and Top with Cheese

Divide the meat sauce between the two squash halves, layering it on top of the strands. Sprinkle generously with shredded mozzarella cheese.

---

Step 6: Bake Until Bubbly

Place the filled squash halves back in the oven and bake for another 10-15 minutes, or until the cheese is melted and golden-brown.

---

Step 7: Garnish and Serve

Remove from the oven, let cool slightly, and sprinkle with fresh parsley before serving. Enjoy your perfectly cheesy, garlicky, and hearty spaghetti squash creation.

Tips for Perfect Cheesy Garlic and Herb Spaghetti Squash with Meat Sauce

• Roast the squash until it gives easily when pierced with a fork to ensure tender, strand-like flesh.
• Don’t overcook the meat; just brown it until no longer pink to avoid dryness.
• Let the meat sauce simmer long enough to deepen the flavor and thicken slightly.
• Use freshly shredded mozzarella for better melting and texture.
• Broil the dish for the last minute or two if you want a perfectly golden cheesy top.

---

Watch Out for These Mistakes While Cooking

• Undercooking the Squash: If the squash is too firm, the strands won’t separate properly.
• Overcrowding the Pan: When cooking the meat, give it space to brown rather than steam.
• Watery Sauce: If your marinara is thin, let it reduce until it’s thick enough to cling to the squash strands.
• Skipping Seasoning: Salt and pepper are essential to bring out all the flavors.
• Using Pre-Shredded Cheese: These often contain anti-caking agents that affect melting.
