Ingredients
The foundation of this recipe is a medium‑size spaghetti squash, which provides a naturally sweet, slightly nutty flavor and a strand‑like texture once cooked. Complementing the squash are three cheeses—Parmesan for sharp depth, mozzarella for melt, and ricotta for a light creaminess. A simple sauce of olive oil, garlic, and fresh herbs ties everything together, while a dash of lemon zest lifts the dish. Optional add‑ins like sautéed spinach or cooked chicken let you tailor the meal to your dietary needs.
Main Ingredients
- 1 large spaghetti squash (about 3‑4 lbs)
- 2 tablespoons olive oil
- 1 cup ricotta cheese
Cheese Blend
- ½ cup grated Parmesan cheese
- 1 cup shredded mozzarella cheese
Sauce & Flavorings
- 3 cloves garlic, minced
- 1 tablespoon fresh lemon zest
- 2 tablespoons fresh parsley, chopped
- Salt and freshly ground black pepper, to taste
Optional Add‑Ins
- 1 cup fresh spinach, wilted
- 8 oz cooked chicken breast, diced
Each component plays a role: the squash provides the hearty “noodle” base, the ricotta adds moisture, while Parmesan and mozzarella give a savory, golden crust. Garlic and lemon zest brighten the sauce, and parsley finishes the dish with a fresh pop. Optional spinach or chicken let you boost protein and greens without altering the core flavor profile.
Step-by-Step Instructions

Preparing the Squash
Start by preheating your oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise and scoop out the seeds with a spoon. Drizzle each half with 1 tablespoon of olive oil, then season with salt and pepper. Place the halves cut‑side down on a parchment‑lined baking sheet. Roast for 35‑40 minutes, or until the flesh is fork‑tender and easily separates into strands.
Creating the Cheese Sauce
While the squash roasts, heat the remaining 1 tablespoon of olive oil in a small skillet over medium heat. Add the minced garlic and sauté for 30‑45 seconds until fragrant, being careful not to let it brown. Remove from heat and stir in the ricotta, lemon zest, and half of the Parmesan. Season with a pinch of salt and pepper; the mixture should be creamy yet spreadable.
Assembling the Boats
- Shred the Squash. Using a fork, gently scrape the roasted flesh to create spaghetti‑like strands. Transfer the strands to a large mixing bowl, keeping the skins in the bowl for later use as a garnish if desired.
- Mix with Sauce. Fold the ricotta‑Parmesan mixture into the squash strands until evenly coated. If you’re adding spinach or chicken, stir them in now so they heat through while the squash finishes baking.
- Fill the Boats. Spoon the cheesy squash mixture back into each roasted squash shell, packing it gently but firmly. The shells act as natural bowls, holding the sauce and cheese inside.
- Add Toppings. Sprinkle the remaining Parmesan and the shredded mozzarella over the tops of each boat. This layer will melt and turn a beautiful golden brown under the broiler.
- Broil to Finish. Switch the oven to broil and place the baking sheet on the top rack. Broil for 3‑5 minutes, watching closely, until the cheese bubbles and the edges turn a deep caramel color. Remove and let rest for 2 minutes.
Plating & Serving
Slide each boat onto a plate, drizzle with a little extra olive oil, and scatter the chopped parsley over the top for a burst of color. Serve immediately while the cheese is still gooey. Pair with a simple arugula salad or a slice of crusty whole‑grain bread for a complete meal.
Tips & Tricks
Perfecting the Recipe
Dry the Squash Flesh. After shredding, pat the strands with a paper towel to remove excess moisture. This prevents a soggy boat and helps the cheese adhere.
Use Fresh Parmesan. Grate Parmesan yourself rather than using pre‑grated. Freshly grated cheese melts more evenly and provides a richer flavor.
Broil with Care. Keep the oven door slightly ajar while broiling; this lets heat escape and prevents the cheese from burning before the tops brown.
Season Early. Salt the squash strands right after shredding so the seasoning penetrates the fibers and balances the richness of the cheese.
Flavor Enhancements
Add a splash of white wine to the garlic skillet for a subtle acidity, or stir in a pinch of red‑pepper flakes for gentle heat. A drizzle of truffle oil just before serving elevates the dish to restaurant quality.
Common Mistakes to Avoid
Avoid over‑roasting the squash; mushy strands lose their bite. Also, don’t skip the resting time after broiling—cutting too soon releases steam that makes the cheese slide off the boat.
Pro Tips
Use a Food Processor. For a quicker shred, pulse the roasted squash in a food processor with the “pulse” setting; this creates uniform strands in seconds.
Season the Broiling Pan. Lightly dust the broiling pan with flour or cornmeal; this prevents the cheese from sticking and adds a tiny crunch.
Finish with Citrus. A final squeeze of lemon juice brightens the heavy cheese and balances the earthy squash.
Batch Cook. Roast multiple squash halves at once and freeze the cooked flesh. This speeds up future meals and reduces prep time.
Variations
Ingredient Swaps
Swap mozzarella for provolone or smoked gouda for a deeper flavor profile. Replace ricotta with Greek yogurt for extra protein and a tangier taste. If you’re avoiding dairy, use a vegan cheese blend and nutritional yeast to mimic Parmesan’s sharpness.
Dietary Adjustments
For a gluten‑free version, ensure any added sauces are certified gluten‑free. To keep it paleo, omit the cheese and replace it with a cashew‑based “cheese” sauce. Keto dieters can double the cheese ratio and serve the boats with a side of cauliflower rice.
Serving Suggestions
Pair the boats with a crisp Caesar salad, roasted cherry tomatoes, or a simple lemon‑garlic quinoa. For a festive touch, drizzle a balsamic reduction over the top just before serving.
Storage Info
Leftover Storage
Allow the boats to cool to room temperature, then transfer each half to a separate airtight container. Refrigerate for up to 4 days. For longer keeping, wrap tightly in plastic wrap, then foil, and freeze for up to 3 months. The squash retains its texture best when stored without the cheese topping, which you can add fresh when reheating.
Reheating Instructions
Reheat in a preheated 350°F oven, covered with foil, for 15‑20 minutes until warmed through. Uncover for the last 3‑4 minutes to melt any added cheese. In a microwave, heat a single boat on medium power for 2‑3 minutes, stirring the interior halfway, and add a splash of broth or water to keep it moist.
