Spaghetti Squash Lasagna

Introduction

This spaghetti squash lasagna gives you all the comfort of the classic Italian dish with a delicious, veggie-packed twist. By using roasted spaghetti squash instead of noodles, you get a wonderfully light and flavorful base that perfectly soaks up the rich, cheesy layers. It’s a satisfying meal that feels indulgent but is surprisingly simple to make.

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).
2. Slice the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the cut sides with a little olive oil or water and season with 1/2 tsp of the garlic salt. Place the halves cut-side down on a baking sheet and roast for 30-40 minutes, or until the flesh is tender and easily shreds with a fork. Let it cool slightly, then use a fork to scrape all the “spaghetti” strands into a large bowl.
3. While the squash roasts, brown the ground turkey in a large skillet over medium-high heat, breaking it up with a spoon as it cooks. Once fully cooked, drain any excess fat. Stir in the marinara sauce and the remaining 1/2 tsp of garlic salt. Reduce heat to low and let it simmer for 5 minutes.
4. In a 9×13 inch baking dish, begin assembling the lasagna. Spread half of the cooked spaghetti squash evenly in the bottom of the dish.
5. Spread the entire 15 oz container of ricotta cheese over the squash layer.
6. If using, sprinkle the 3 cups of baby spinach evenly over the ricotta.
7. Pour the entire turkey and marinara sauce mixture over the spinach/ricotta layer, spreading it out evenly.
8. Top with the remaining half of the spaghetti squash.
9. Tear or slice the 6 oz of fresh mozzarella and distribute it evenly over the top layer of squash.
10. Bake uncovered in the preheated oven for 20-25 minutes, or until the cheese is melted, bubbly, and starting to brown. Let the lasagna rest for 10 minutes before serving to allow it to set.

Variations

• Meatless Version: Simply omit the ground turkey and add a layer of sautéed mushrooms or bell peppers with the spinach for a vegetarian meal.
• Crispy Top: For a golden, crispier cheese topping, broil the lasagna for the final 2-3 minutes of cooking.
• Individual Servings: Assemble the lasagna in small, oven-safe ramekins or baking dishes for perfect single-serving portions, reducing the bake time slightly.
• Flavor Boost: Add a pinch of red pepper flakes to the turkey marinara mixture or mix a tablespoon of Italian seasoning into the ricotta for an extra flavor punch.

Tips for Success

• Dry the Squash: After scraping the squash, place the strands in a clean kitchen towel or paper towels and gently press to remove excess moisture. This prevents a watery lasagna.
• Prep Ahead: Roast the spaghetti squash and cook the turkey sauce up to two days in advance. Simply assemble and bake when ready.
• Rest Before Serving: Allowing the lasagna to rest for a full 10 minutes after baking is crucial—it helps the layers set so you get neat slices instead of a runny casserole.
• Fresh vs. Pre-Shredded: Fresh mozzarella melts beautifully and creates those classic, gooey cheese pulls. Pre-shredded cheese often contains anti-caking agents that can make it melt less smoothly.

Storage & Reheating

Store any leftover lasagna in an airtight container in the refrigerator for up to 4 days. To reheat, cover a portion with foil and warm in a 350°F oven until heated through, or microwave individual servings in 30-second intervals.

FAQ

Can I use a different type of meat?

Yes, the recipe works well with ground beef, chicken, or Italian sausage as a direct substitute for the ground turkey.

How do I easily cut a spaghetti squash?

Poke the whole squash a few times with a knife, microwave it for 3-5 minutes to soften the skin slightly, then carefully slice it in half. Always use a sharp, sturdy knife on a stable surface.

Is the spinach necessary?

No, the spinach is entirely optional. It adds color, nutrients, and a mild flavor, but the lasagna is still delicious without it.

Can I freeze this lasagna?

My lasagna is watery. What happened?

This is usually due to excess moisture in the spaghetti squash. Be sure to press the cooked squash strands in a towel before assembling. Also, letting the lasagna rest before serving allows excess liquid to be absorbed.

What can I serve with this lasagna?

It’s a complete meal on its own! A simple side salad with a light vinaigrette or some garlic bread are classic, complementary choices.
