👩🏽‍🍳 Top tips for the best stuffed spaghetti squash

While this is an easy recipe, following these tips will make sure you have a perfect stuffed spaghetti squash every time! Then, prep the squash. Cut the squash in half and remove the seeds. I pierce the skin with a fork a few times and then pop it in the microwave to soften the skin before I slice the squash. Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add 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. ⭐ Make the filling in advance. This recipe can be a lot easier to prepare when you make the sauce in advance (freeze or chill the refrigerator), cook the squash the day before, and then bake it on the day of your special gathering.

Check the oven for doneness. After 15 minutes of baking, check the squash every two to three minutes to ensure the right texture. To check for doneness, the strands of the squash should easily pull away from the skin using a fork. Lessen moisture. When sautéing vegetables, lower the temperature and cook them until they release water. Allow water to evaporate before adding the next ingredient. Don’t overstuff the squash. Be mindful not to overstuff the spaghetti squash halves. A moderate amount of filling ensures balance between the spaghetti squash noodles and the sauce, and allows the squash to cook evenly.
