Common Mistakes to Avoid
When preparing stuffed spaghetti squash, it’s easy to make a few common errors. Here’s how to avoid them:
Skipping the seasoning: Not seasoning your squash and filling can lead to bland flavors. Always season generously with salt and pepper before baking.
Overcooking the squash: Cooking the spaghetti squash for too long can result in mushy strands. Aim for about 35 minutes at 400°F for perfect texture.
Using low-quality marinara sauce: A poor-quality sauce can ruin the dish. Choose a tasty marinara that enhances your filling instead of overpowering it.
Not draining excess moisture: If there’s too much liquid, your filling may become soggy. Drain off any extra liquid from the cooked squash before adding your ingredients.
Ignoring cheese options: Sticking only to one type of cheese can limit flavor. Experiment with different cheeses like mozzarella or feta for added depth.
