Ingredients for Lasagna Stuffed Squash
See full recipe card below this post for ingredient quantities and full instructions.
- Olive oil – You can also use coconut oil if preferred.
- Spaghetti squash – Cut this in half, or slice it in wedges, and serve if you want to make a smaller portion.
- Grated mozzarella cheese – Freshly grated cheese has the best flavor and texture! Pre-grated varieties contain anti-caking agents that prevent them from melting.
- Ricotta cheese – Cottage cheese could be an option in a pinch.
- Baby spinach – I’ve also used frozen spinach. Just be sure to drain any excess water well before adding.
- Marinara sauce – You can use homemade or store-bought.
- Parmesan cheese – Again, fresh tastes so good!
- Salt and pepper to taste
Variations
Here are a few variations that you could try to tweak or easily change this low-carb lasagna recipe:
- Add meat. Adding cooked ground pork, ground chicken, or ground beef can be a great way to add protein and flavor.
- Change the type of cheese. Mozzarella is the typical cheese used with lasagna, but feel free to switch it up! Cheddar cheese or Colby Jack cheese also tastes great.
- Make it spicy. Adding a bit of cayenne pepper or red pepper flakes can really change the flavor profile adding a dash of heat!
How To Make Stuffed Lasagna Spaghetti Squash
- Preheat: Preheat the oven to 400 degrees.
- Cut the squash: Half the squash, remove the seeds, and place both halves on a baking sheet cut side up.
- Bake: Transfer the squash to the oven, and cook for 20 minutes or until tender.
- Cook the spinach: While the squash is baking, add the olive oil and the spinach to a saucepan over medium heat. Cook for 10 minutes.
- Drain the spinach: Let the spinach cool, and transfer it to a paper towel. Press out as much water as possible, and chop it into pieces.
- Mix: Add the spinach to a bowl with the ricotta cheese. Mix well.
- Scrape: Remove the cooked squash from the oven, and let it cool. Scrape the insides of the squash with a fork, and place the flesh of the squash into a bowl.
- Garnish: Add 3-5 tablespoons of the spaghetti squash strands to the bottom of the squash shell. Then, add the marinara followed by the ricotta mixture, and top with the grated cheese. Repeat the steps for a second layer.
- Broil: Place the squash in the broiler to melt the cheese.
Quick Tip
If you don’t want to make this mixture inside of the spaghetti squash shell, you can cook the squash. Then, follow the directions layering the mixture in a casserole dish or heat-safe bowl.
How to Store Stuffed Squash
Store leftovers in an airtight container in the refrigerator for up to 3 days.
When you want to reheat the dish, I recommend warming the spaghetti squash lasagna for 1-2 minutes in the microwave. You can also reheat low and slow in the oven. Just be careful not to let it burn!
Serving Suggestions
To keep with the low-carb theme, serve this with a delicious summer salad or a side of roasted veggies.
You can also serve this as a side dish and pair it with something delicious, like these Grilled Chicken Kabobs or Garlic Parmesan Wings!
FAQs
It is! Not only is it low-carb, but this stuffed lasagna spaghetti squash recipe is gluten-free as well. You can also make it dairy-free easily by using a dairy-free cheese blend if needed.
Freezing is not recommended for this squash dish. It changes the texture of the squash, and it will cause it to become too runny from excess water being released as it thaws. Fresh is best!
If you want to do a bit of prep work ahead of time, go for it! You can cook the spinach ahead of time, prep and slice the squash, and even make the ricotta mixture as well. Then, just layer everything together, and bake when you’re ready to serve.
