Spaghetti Squash Lasagna

Introduction

This healthier take on lasagna swaps traditional noodles for tender strands of spaghetti squash, creating a naturally low-carb and gluten-free meal. You’ll love how the rich turkey marinara layer and creamy cheeses create a satisfying, comforting dish without the heaviness. It’s a fantastic way to enjoy classic Italian flavors in a nutritious package.

Prep & Cook Time

• Prep Time: 15 minutes
• Cook Time: 45 minutes
• Total Time: 1 hour
• Servings: 8

Ingredients

• 1 2-3 lbs spaghetti squash
• 1 lb ground turkey
• 1.5 cups marinara sauce (no sugar added)
• 1 tsp garlic salt (divided)
• 15 oz ricotta
• 6 oz fresh mozzarella
• 3 cups baby spinach (optional)

Instructions

1. Preheat your oven to 400°F (200°C). Carefully cut the spaghetti squash in half lengthwise and scoop out the seeds. Place the halves cut-side down on a baking sheet. Bake for 30-35 minutes, or until the flesh is tender and easily shreds with a fork. Once cool enough to handle, use a fork to scrape all the flesh into strands. Set aside.
2. While the squash bakes, cook the ground turkey in a large skillet over medium heat, breaking it up with a spoon, until no longer pink. Drain any excess fat. Stir in the marinara sauce and 1/2 teaspoon of the garlic salt. Simmer for 5 minutes, then remove from heat.
3. In a medium bowl, mix the ricotta cheese with the remaining 1/2 teaspoon of garlic salt.
4. Reduce the oven temperature to 375°F (190°C). In a 9×13 inch baking dish, begin assembling the lasagna: Spread the cooked spaghetti squash strands evenly on the bottom as your first “noodle” layer.
5. If using, distribute the baby spinach over the squash. Next, dollop the seasoned ricotta mixture over the layer and spread it gently.
6. Pour the turkey marinara mixture evenly over the ricotta layer.
7. Tear or slice the fresh mozzarella and distribute it evenly over the top.
8. Bake at 375°F for 20-25 minutes, or until the cheese is melted and bubbly. Let the lasagna stand for 5-10 minutes before slicing and serving.

Variations

• Single-Serve Style: For easy portion control, assemble the layers in individual oven-safe ramekins.
• Extra Crispy Top: Place the baking dish under the broiler for the final 2-3 minutes of cooking to get a beautifully browned, bubbly cheese crust.
• Herb Infusion: Stir a tablespoon of Italian seasoning or fresh chopped basil into the ricotta mixture for an extra flavor boost.
• Deconstructed Bowl: Serve the components separately for a “lasagna bowl”—layer hot spaghetti squash, turkey sauce, and dollops of ricotta and mozzarella in individual bowls.

Tips for Success

• Dry the Squash: After scraping the squash, place the strands in a clean kitchen towel and gently squeeze to remove excess moisture. This prevents a watery final dish.
• Brown the Turkey Well: Let the ground turkey get a nice sear and develop color in the skillet before adding the sauce; it builds a deeper, richer flavor.
• Prep Ahead: Bake and shred the spaghetti squash up to 2 days in advance to significantly cut down on active prep time on the day you cook.
• Fresh vs. Shredded Mozzarella: Using fresh mozzarella as listed gives superior melt and flavor, but if using pre-shredded, add it in the last 10 minutes of baking to prevent it from burning.

Storage & Reheating

Store leftover lasagna in an airtight container in the refrigerator for up to 4 days. To reheat, place a portion in an oven-safe dish, cover with foil, and bake at 350°F until warmed through (about 15-20 minutes). You can also reheat individual servings in the microwave for 1-2 minutes.

FAQ

Can I use a different meat?

While the recipe specifies ground turkey, the method works perfectly with ground beef, chicken, or Italian sausage. Keep the weight at 1 lb.

My lasagna is watery. What happened?

The most common cause is not removing enough moisture from the spaghetti squash. Always squeeze the shredded squash in a towel before assembling.

Is the spinach necessary?

No, the spinach is listed as optional. It adds color, fiber, and nutrients, but the recipe is complete without it.

Can I make this recipe dairy-free?

This recipe is not designed to be dairy-free as written, as ricotta and mozzarella are core components. Removing them would fundamentally change the dish.

Can I freeze spaghetti squash lasagna?

Yes. Assemble and bake completely, then let it cool. Wrap the dish tightly or portion into freezer-safe containers. Freeze for up to 3 months. Thaw in the refrigerator overnight before reheating.

How do I know when the spaghetti squash is fully cooked?

The squash is done when the skin gives slightly to pressure and the flesh shreds easily into spaghetti-like strands when scraped with a fork.
