Whip up this delicious stuffed spaghetti squash recipe bursting with veggies, herbs, and gooey mozzarella in no time. It's quick, flavorful and a perfect main for any occasion.
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped onion and cook for 2-3 minutes until it becomes translucent. Stir in the minced garlic and cook for another 30 seconds.
Add the diced tomatoes, red bell pepper and zucchini to the skillet. Cook for 5-7 minutes, or until the vegetables start to soften.
Mix in the cooked quinoa (or rice), dried Italian seasoning, salt, and black pepper to the skillet. Stir well and cook for an additional 2-3 minutes.
Divide the vegetable and quinoa mixture evenly between the two spaghetti squash halves, pressing down gently to pack the filling.
Sprinkle shredded mozzarella cheese evenly over the stuffed squash halves.
Place the stuffed squash in the oven and bake for 15-20 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let it cool for a few minutes. Garnish with fresh basil leaves if desired. Serve and enjoy!
Notes
Prepare the filling in advance by making the sauce ahead (freeze or chill), cooking the squash the day before, and baking it on the day of your special gathering.
Check the squash for doneness after 15 minutes of baking, and every two to three minutes thereafter. The strands should easily pull away from the skin with a fork.
When sautéing vegetables, lower the temperature and cook until they release water. Allow water to evaporate before adding the next ingredient to reduce moisture.
Avoid overstuffing the squash halves. A moderate amount of filling ensures a balance between the spaghetti squash noodles and the sauce, promoting even cooking.
