Prep & Cook Time
- Prep Time: 15 minutes
- Cook Time: 45 minutes
- Total Time: 60 minutes
- 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
- 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 and roast for 25-30 minutes, or until the flesh is tender and easily shreds with a fork. Let cool slightly, then use a fork to scrape all the flesh into “noodles.” Place the noodles in a clean kitchen towel or paper towels and gently press to remove excess moisture.
- While the squash roasts, cook the ground turkey in a large skillet over medium heat until no pink remains, breaking it up as it cooks. Drain any excess fat. Stir in the marinara sauce and 1/2 teaspoon of the garlic salt. Set aside.
- In a medium bowl, mix the ricotta cheese with the remaining 1/2 teaspoon of garlic salt.
- Assemble the lasagna in a 9×13 inch baking dish. Start by spreading half of the turkey marinara mixture evenly on the bottom. Next, create a layer with all of the shredded spaghetti squash. Spread the seasoned ricotta evenly over the squash. If using, scatter the baby spinach over the ricotta. Top with the remaining turkey marinara mixture.
- Tear or slice the fresh mozzarella and distribute it evenly over the top layer.
- Bake in the preheated 400°F (200°C) oven for 20-25 minutes, or until the cheese is melted, bubbly, and slightly golden. Let the lasagna rest for 5-10 minutes before slicing and serving.
Variations
- Individual Portions: Assemble the lasagna in smaller oven-safe dishes or ramekins for perfect personal servings and easier portion control.
- Crispy Top: For a more browned, crispy cheese top, place the dish under the broiler for the final 1-2 minutes of baking (watch closely!).
- No-Ricotta Layer: Mix the ricotta directly into the cooked spaghetti squash “noodles” before layering for a more integrated, creamy texture throughout.
- Herb Boost: Stir a handful of chopped fresh basil or parsley into the ricotta mixture or sprinkle it between the layers for a burst of fresh flavor.
Tips for Success
- Dry the Squash: The most crucial step is thoroughly draining the cooked spaghetti squash. Excess moisture will make your lasagna watery.
- Season in Stages: Dividing the garlic salt between the meat sauce and the ricotta ensures every layer is perfectly seasoned.
- Rest Before Serving: Letting the baked lasagna sit for 5-10 minutes allows the layers to set, making it much easier to slice into clean portions.
- Brown the Turkey: Let the ground turkey get a little caramelized in the pan before adding the sauce for a deeper, richer flavor base.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave until hot, or cover the baking dish with foil and reheat in a 350°F oven for 15-20 minutes.
FAQ
Can I make this ahead of time?
Yes, you can assemble the lasagna completely, cover it tightly, and refrigerate it for up to 24 hours before baking. You may need to add 5-10 minutes to the bake time if starting from cold.
Is the spinach necessary?
No, the spinach is optional. It adds color, nutrients, and a bit of texture, but the lasagna is still delicious without it.
Can I use a different meat?
Yes, the recipe instructions work perfectly with ground beef, chicken, or Italian sausage as a substitute for the ground turkey. Just ensure it’s fully cooked before assembling.
My lasagna is watery. What happened?
This is almost always due to not removing enough moisture from the roasted spaghetti squash. Next time, be sure to press the shredded squash firmly in a towel or colander before layering.
Can I freeze Spaghetti Squash Lasagna?
Yes. Assemble and bake it, then let it cool completely. Wrap tightly or store in a freezer-safe container for up to 3 months. Thaw in the refrigerator overnight before reheating.
What can I serve with this?
A simple green salad with a light vinaigrette or some roasted garlic bread (for those not avoiding carbs) makes a perfect, easy side.
