A note from Taryn: Sometimes it even takes a village to have a blog. I had surgery last week, and I'll be completely fine, but my recovery is going slowly. So, I asked some blogging friends to join me here at Joy Filled Eats! I'm excited to share that I'm going to have a bunch of guest posts over the next month or two. I'm hoping to be back in the kitchen soon because I need Christmas cookies, but all their recipe ideas sound amazing. I can't wait to share them with you! My first guest is Jenny from A Thing Shared. She has created a delicious sheet pan Spaghetti Squash Lasagna that I know will be a hit with my kids and yours. If you've enjoyed this spaghetti squash lasagna recipe make sure to pop on over to her blog for some more yumminess.

I’m grateful to Taryn for letting me share this Spaghetti Squash Lasagna with you today! I hope you enjoy it -- my family certainly does. It has all of the satisfying richness of a classic lasagna so it’s perfect for these wintery nights when you’re craving comfort food. But the spaghetti squash lightens up the meal quite a bit, leaving you feeling good when the meal is over.
Sometimes my kids, pasta-lovers aged 2, 5, and 6, protest if I use spaghetti squash in lieu of regular pasta, so I usually scoop some noodles separately onto their plate too (my favorite types of pasta for my kids are from the Banza brand, which is made from chickpeas). So everyone leaves the table happy.

The Best Way to Cook Spaghetti Squash
If you’ve tried spaghetti squash before, and either found it too time-consuming to prepare or too bland for your tastes, give it another shot with my method. The preparation I recommend cuts the cooking time in half and leaves you with long, caramelized, flavorful noodles that taste nothing like the soggy, tasteless spaghetti squash you may have had in the past.
- 1 3-4 lbs spaghetti squash
- 1 lb ground turkey
- 2 cups marinara sauce no sugar added
- 15 oz ricotta
- 6 oz fresh mozzarella
- 3 cups baby spinach optional
- Preheat oven to 450 to cook the spaghetti squash. This high temperature will significantly reduce the cooking time as well as eliminate excess moisture and help caramelize the squash.
- Cut the spaghetti squash into thirds crosswise through the middle (not from base to stem) so you end up with three rounds. This enables you to get longer “spaghetti” strands from the squash after cooking, because the strands naturally run around the middle of the squash, rather than from stem to base.
- Remove the seeds by using a knife or spoon to separate them from the flesh of the squash. Place squash rounds on a greased baking sheet and sprinkle with salt. You can trim a portion from the base and the stem, too, so you can lay the pieces flat.
- Place baking sheet in the oven on the middle rack and roast for 30-40 minutes, until squash is tender when pierced with a knife. Let cool.
- While squash cools, cook the turkey in saute pan over medium-high heat until browned and cooked through. Add marinara to pan and mix.
- When squash cools enough to handle it, use a fork to remove strands from the rind. Separate stands so they become “spaghetti-like” and then transfer them to the greased casserole dish, spreading to cover the bottom. Top with meat sauce. Drop spoonfuls over ricotta over the dish, and alternate with rounds of mozzarella so most of the casserole is covered with cheese.
- You can store the casserole at this point to be baked later, or you can bake immediately. When you’re ready to bake, preheat oven to broil. Place casserole under the broiler for 5-10 minutes until cheese begins to brown. Remove casserole from oven and tuck baby spinach leaves into the casserole between cheese (if spinach is added earlier, it will wilt too much). Return casserole to broiler for one more minute until spinach softens.
- Remove casserole from oven and let cool for 15 minutes. Enjoy! The lasagna is great leftover too.
