The Ultimate Twice Baked Spaghetti Squash: Healthy, Hearty, and Delicious with Turkey Sausage
This Twice Baked Spaghetti Squash recipe is a game-changer for healthy eating, offering a delightful combination of rich, homemade turkey sauce and generous amounts of melted mozzarella cheese. It’s the perfect dish for those seeking a meal that is genuinely healthy, incredibly hearty, and surprisingly easy to prepare. Say goodbye to carb-heavy pasta and hello to a vibrant, flavorful alternative that will satisfy your cravings without any guilt.

Like many home cooks, I confess to having a rather unfortunate habit of impulsively buying beautiful squash varieties at the farmer’s market, only to let them sit on my kitchen counter for what feels like an eternity. I am not exaggerating when I say months! It’s a recurring cycle of good intentions meeting a busy schedule, and the squash often loses the battle.
I still remember a specific incident when my husband and I were living in Cleveland. I spotted a magnificent butternut squash and, filled with ambitious culinary plans, envisioned creating a comforting soup. That poor squash, however, ended up being a permanent fixture on our counter for a staggering eight months! It became a running joke between us, a testament to my procrastination. Who does that? Apparently, I do.

This habit persisted. Several months later, captivated by its unique appearance, I picked up a Delicata Squash. Despite its charming stripes, I found myself utterly clueless about how to prepare it. It sat there, a decorative but unused addition to my kitchen, until its fate was sealed – another forgotten squash.

And just when I thought I might finally conquer my squash procrastination, after finally giving up on the languishing Delicata, I did it again. I acquired not one, but several spaghetti squash! Clearly, I had learned absolutely nothing from my previous wasteful and slightly embarrassing experiences. My counter was once again home to a collection of potential meals waiting for inspiration to strike.

Fortunately, inspiration arrived just in time. I was watching Martha’s Cooking School, and lo and behold, Martha Stewart herself demonstrated how to roast spaghetti squash perfectly. This was the nudge I needed! That very same week, Tieghan from the incredibly talented Half Baked Harvest (she’s truly amazing, by the way!) posted her recipe for Roasted Garlic Spaghetti Squash Lasagna Boats. That was it; I was completely sold on the idea of incorporating spaghetti squash into my cooking. The combination of these two culinary giants finally motivated me to embrace this versatile vegetable.

This Twice Baked Spaghetti Squash recipe, much like my zucchini lasagna, offers a truly guilt-free way to enjoy two of my absolute favorite comfort foods: a rich, savory red meat sauce and, of course, an abundance of gooey, melted cheese. It’s the perfect solution for satisfying those deep cravings for hearty, cheesy meals without compromising on your healthy eating goals. The spaghetti squash acts as a fantastic, low-carb base, providing a satisfying texture that mimics traditional pasta.

Mmmmm, just look at that melty, cheesy goodness! The sight of bubbling, golden-brown mozzarella covering a vibrant, rich turkey sauce truly makes this dish irresistible. It’s not just a meal; it’s an experience for your taste buds, promising warmth and comfort in every single bite. The blend of savory sauce and creamy cheese makes it an instant classic in any home.

Why Spaghetti Squash is a Healthy Superfood
Spaghetti squash is, quite frankly, shockingly good! When seasoned simply with a drizzle of olive oil, a pinch of salt, a dash of freshly ground pepper, and a hint of fresh nutmeg, it develops a nutty, subtly sweet, and incredibly comforting flavor. I often find myself snacking on it straight from the baking sheet, even before adding any accoutrements. And the best part? It boasts a mere 31 calories per cup, making it an incredibly light yet satisfying alternative to traditional pasta. Who can argue with such fantastic nutritional benefits? I certainly would not!
Its unique texture, separating into pasta-like strands when cooked, is what makes it so popular. It’s a fantastic low-carb, gluten-free option for anyone looking to lighten up their meals without sacrificing flavor or volume. Spaghetti squash is also packed with vitamins, including Vitamin C and B vitamins, as well as minerals like manganese and potassium, contributing to overall well-being. This incredible versatility and nutritional profile make it a star ingredient in any healthy kitchen.
The Magic of the Twice Baked Method
The “twice baked” method for this spaghetti squash recipe elevates it from a simple side dish to a gourmet experience. The first bake perfectly cooks the squash, allowing its strands to tenderize and develop their signature texture. But the magic truly happens during the second bake. After the squash is scooped out, mixed with the delectable turkey sausage sauce, and generously topped with cheese, it’s returned to the oven (or broiler). This second round of heat allows the flavors to meld beautifully, the sauce to warm through thoroughly, and most importantly, the mozzarella to melt into a glorious, bubbly, golden-brown crust. This process ensures every forkful is infused with flavor and offers that irresistible cheesy pull, transforming a simple vegetable into a truly indulgent yet healthy meal.
Crafting the Perfect Turkey Sausage Meat Sauce
The heart of this Twice Baked Spaghetti Squash lies in its rich, homemade turkey sausage meat sauce. Using mild turkey sausage offers a leaner protein option without sacrificing flavor. When browned, the turkey sausage releases savory juices that form the base of a deeply flavorful sauce. Combining this with your favorite pasta sauce creates a robust and satisfying filling. You can enhance the sauce further by adding finely diced onions, garlic, or a touch of red wine during the browning process for an even deeper flavor profile. The key is to let the sauce simmer gently, allowing all the flavors to marry and create that comforting, homemade taste that pairs so beautifully with the delicate strands of spaghetti squash.
The Essential Role of Mozzarella Cheese
While any cheese can be used, I highly recommend using freshly grated mozzarella cheese for this recipe. The difference in overall flavor and melt factor is truly substantial. Pre-shredded cheeses often contain anti-caking agents that can hinder a smooth, creamy melt and sometimes alter the taste. Fresh mozzarella, on the other hand, melts into a beautifully gooey, stretchy, and richly flavored topping that makes every bite of this Twice Baked Spaghetti Squash a luxurious experience. Its mild, milky flavor perfectly complements the robust turkey sauce without overpowering the delicate taste of the squash. In a pinch, of course, pre-grated will work, but for the ultimate indulgence, go fresh!
I loved this recipe so much that I’m already planning to incorporate more spaghetti squash into my cooking this week! I’ll be using some for a delightful Vegetarian Chili and a hearty Spaghetti Squash Lasagna. It’s truly a testament to how versatile and delicious this humble vegetable can be, opening up a world of healthy meal possibilities. If I’m eating this healthy, it probably means I can justify more dessert, like this decadent chocolate zucchini cake. No? A girl can dream!

This dish isn’t just a casual meal; it quickly became a personal obsession. When my husband was out of town last month, I made a large batch of this Twice Baked Spaghetti Squash, and I’m not ashamed to admit, I ate it every single night for an entire week. Every. Single. Night. It’s that good, that comforting, and that easy to reheat, making it the ultimate healthy weeknight dinner for one (or more!). It perfectly encapsulates the balance of satisfying flavor and nourishing ingredients.
So, without any further delay, make your next grocery run an opportunity to pick up some beautiful spaghetti squash. Don’t let them sit on your counter! Instead, whip up these incredibly healthy, utterly delicious, and deeply satisfying Twice Baked Spaghetti Squash boats. You won’t regret it.

FULL DISCLOSURE: As I type this, there is, in fact, another butternut squash sitting patiently on my counter. I purchased it several weeks ago with renewed determination to finally make that butternut squash soup I’ve been dreaming of for years. Perhaps publicly divulging my perpetual squash problem will finally force me to actually MAKE IT! Here’s to hoping I break the cycle!


Twice Baked Spaghetti Squash with Turkey Sausage

Ingredients
- 2 medium spaghetti squash
- ¾ pound mild turkey sausage
- 2 cups pasta sauce
- 8 oz fresh mozzarella cheese grated [this makes a HUGE difference in overall flavor, but you can also use the pre-grated type in a pinch]
- Freshly cracked pepper
- Kosher salt
- Freshly ground nutmeg
Instructions
-
Preheat oven to 425°. Line a rimmed baking sheet with parchment paper (this will save your baking sheets and also you a lot of cleanup!)
-
Halve your spaghetti squash lengthwise, scoop out the seeds and stringy bits from the center, and place the halves face up on your prepared baking sheet; drizzle generously with olive oil and coarse kosher salt. Flip them over and drizzle with more olive oil and salt. Be sure to set aside the insides of the squash to roast the seeds later for a crunchy snack!
-
Bake in your preheated oven until the skin easily gives when you poke it with a fork. It will feel soft and will indent, indicating it’s perfectly cooked. This baking time will vary drastically by the size of your squash; typically, it takes between 30-60 minutes.
-
While the spaghetti squash bakes, prepare your delicious filling. Brown some mild turkey sausage in a skillet over medium heat, breaking it up with a spoon as it cooks. Once browned, drain any excess fat, then combine the cooked turkey sausage with your favorite pasta sauce. Heat gently in a medium saucepan until warmed through and flavors are well blended.
-
Once the squash is cooked and cooled enough to handle, grip one half with tongs or a clean kitchen towel and use a fork to scrape out the spaghetti-like strands into a medium bowl.
-
Repeat this process with all remaining squash halves until all the tender strands are collected in the bowl.
-
Season the spaghetti squash strands generously with additional olive oil, kosher salt, freshly ground black pepper, and fresh ground nutmeg. The fresh nutmeg makes a significant difference; leave this out if you only have the pre-ground type, as it’s just not the same! I like to season the squash in batches, fluffing it with a fork to toss and coat each strand evenly.
-
Now, it’s time to assemble your Twice Baked Spaghetti Squash! You can either fill the empty squash skins (creating beautiful “boats”) or use individual ovenproof ramekins or one larger baking dish. Divide the seasoned spaghetti squash evenly among your chosen vessels. Top each with approximately ¼ of the turkey sausage pasta sauce, then liberally sprinkle freshly grated mozzarella cheese over the top.
-
Place the filled squash boats or dish under the broiler for a few minutes until the cheese melts, becomes bubbly, and achieves a beautiful golden-brown color. Watch carefully to prevent burning. Serve immediately and enjoy!
