Ingredients You’ll Need
This Spinach Stuffed Spaghetti Squash Recipe requires simple, clean ingredients that come together to create a rich blend of flavors and textures. Each element plays an important role—from the nutty, roasted spaghetti squash base to the creamy ricotta filling and the melty mozzarella topping, every ingredient brings something special to the table.
- 1 large spaghetti squash: The star of this dish offering a delicate, noodle-like texture perfect for stuffing.
- 1 tablespoon olive oil: Used to coat the squash inside for even roasting and a touch of richness.
- Salt and freshly ground black pepper (to taste): Essential for seasoning and bringing out the natural flavors.
- 2 cups fresh spinach leaves, chopped: Adds vibrant green color and a fresh, slightly earthy taste.
- 1 tablespoon butter: Helps sauté the garlic and spinach, adding a silky texture.
- 2 cloves garlic, minced: Brings wonderful aroma and depth to the filling.
- 1/2 cup ricotta cheese: Offers creamy richness that binds the filling perfectly.
- 1/4 cup grated Parmesan cheese: Adds a sharp, nutty flavor for extra complexity.
- 1/4 teaspoon crushed red pepper flakes (optional): Gives a subtle spicy kick for warmth and enhanced flavor.
- 1 cup shredded mozzarella cheese: Melts beautifully on top, creating a golden, bubbly crust.
How to Make Spinach Stuffed Spaghetti Squash Recipe
Step 1: Prepare and Roast the Squash
Start by preheating your oven to 400°F (200°C). Slice your spaghetti squash carefully in half lengthwise and scoop out the seeds. Drizzle the inside of each half with olive oil and season generously with salt and freshly ground black pepper. Placing the squash cut-side down on a parchment-lined baking sheet helps it roast evenly and develop that tender texture needed for scraping later.
Step 2: Roast Until Tender
The magic happens in the oven. Roast your squash for about 40 minutes. You’ll know it’s done when the flesh is tender and the strands easily separate with a fork. This step is crucial as it forms the base “noodles” of the dish, offering a mild, slightly sweet foundation that’s gluten-free and naturally low-carb.
Step 3: Cook the Spinach Filling
While the squash roasts, melt butter in a medium skillet over medium heat. Add minced garlic and cook just until fragrant – around 1 minute. Next, toss in the chopped spinach. It wilts quickly, only taking about 3 to 4 minutes to turn bright green and tender. This spinach mixture forms the heart of the filling, bringing freshness and vibrant flavor.
Step 4: Mix the Cheesy Filling
In a large bowl, combine the sautéed spinach, ricotta cheese for creaminess, Parmesan cheese for tangy depth, and optional crushed red pepper flakes to add a subtle heat. Stir everything gently to blend all those lovely flavors into a luscious filling that perfectly complements the roasted squash.
Step 5: Assemble and Bake
Once your spaghetti squash halves are cool enough to handle, use a fork to scrape out the strands gently from the inside. This creates the “spaghetti” strands that are the foundation of the dish. Divide your cheesy spinach mixture evenly between the two halves, stuffing each one generously. Top with shredded mozzarella cheese, which will melt into a gorgeous golden crust as you return the squash to the oven. Bake for an additional 10 minutes until the cheese is melted and bubbly, signaling it’s ready to enjoy.
How to Serve Spinach Stuffed Spaghetti Squash Recipe

Garnishes
To take this Spinach Stuffed Spaghetti Squash Recipe to the next level, sprinkle freshly chopped herbs like basil or parsley on top just before serving. A light drizzle of extra virgin olive oil or a squeeze of fresh lemon juice can brighten the dish wonderfully. For those who love a bit of crunch, toasted pine nuts add texture and a nutty flavor that pairs beautifully with the creamy filling.
Side Dishes
This recipe shines as a main dish but pairs perfectly with fresh, crisp salads, such as a simple arugula and cherry tomato mix with a balsamic vinaigrette. Roasted root vegetables or garlic butter green beans are great warm sides that complement the cheesy, rich flavors of the stuffed squash. If you prefer something heartier, a crusty whole wheat bread works well to mop up any cheesy, spinachy goodness.
Creative Ways to Present
For a fun twist, serve the stuffed spaghetti squash halves on individual plates for a rustic but elegant look. You can also scoop out the spaghetti strands mixed with the filling to create stuffed squash “boats” in smaller portions, which are perfect for entertaining. Another idea is to sprinkle some extra Parmesan or indulge with crispy breadcrumbs on top before the final bake for a crunchy topping that contrasts the creamy interior delightfully.
Make Ahead and Storage
Storing Leftovers
Spinach Stuffed Spaghetti Squash Recipe leftovers can be stored in an airtight container in the refrigerator for up to 3 days. As the flavors meld, the dish actually becomes even more flavorful. Just be sure to cool it completely before refrigerating to maintain texture and freshness.
Freezing
If you want to enjoy this Spinach Stuffed Spaghetti Squash Recipe later, you can freeze individual portions wrapped tightly in plastic wrap and placed inside a freezer-safe container or bag. It stays delicious for up to 2 months. Thaw in the refrigerator overnight before reheating to keep the filling creamy and avoid watery squash.
Reheating
To reheat, pop the stuffed squash halves in a preheated oven at 350°F (175°C) for about 15-20 minutes or until warmed through and the cheese softly bubbles again. Avoid microwaving if possible, as this can sometimes make the squash watery. Using the oven helps preserve the texture and brings back that freshly baked feel.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! If you have only frozen spinach on hand, just make sure to thaw it fully and squeeze out excess moisture before sautéing. This prevents the filling from becoming too watery and ensures the texture stays just right in the Spinach Stuffed Spaghetti Squash Recipe.
Is there a way to make this recipe vegan?
Yes! To veganize this dish, substitute butter with olive oil or vegan margarine, use vegan ricotta and mozzarella alternatives, and opt for nutritional yeast instead of Parmesan. The essence and heartiness of the Spinach Stuffed Spaghetti Squash Recipe remain intact with these simple swaps.
How do I know when the spaghetti squash is fully cooked?
The best test is to poke a fork into the squash strands; they should come apart easily like al dente pasta without being mushy. The flesh should also feel tender when pierced. If it resists or is crunchy, it needs more roasting time.
Can I add other vegetables or proteins to the filling?
Definitely! This recipe is versatile. You can mix in sautéed mushrooms, caramelized onions, or even cooked ground turkey or Italian sausage for a heartier meal. Just adjust the seasoning accordingly and enjoy a personalized Spinach Stuffed Spaghetti Squash Recipe every time.
What if I don’t have Parmesan cheese?
If you’re out of Parmesan, Pecorino Romano or Asiago are great substitutes for a similar sharp, salty flavor. If you prefer a milder taste, you can leave it out or add a little extra mozzarella for creaminess. The filling will stay delicious and full of character.
