Eating seasonally is one of the best parts about home cooking. I don’t know about you, but when I think about autumn and winter, I think of warm, comforting casseroles.
Too often, though, casseroles are recipes packed with heavy, refined carbs and few, if any, vegetables. While they may taste good, you won’t feel too great after a serving. That’s what makes this healthy spaghetti squash casserole such a stellar cold-weather meal.
Here, spaghetti squash replaces the pasta you typically find in casseroles. You’ll add a colorful medley of vegetables, but with both mozzarella and raw goat cheese, this easy-to-make spaghetti squash casserole feels indulgent — it’s the best of both worlds!
What Makes This Spaghetti Squash Casserole So Healthy?

Best of all, spaghetti sauces is packed with nutrients you just won’t find in pasta. Its bright hue is thanks to the beta-carotene. This cartenoid is one of the reasons why spaghetti squash is full of antioxidants and great for your skin, eyes and respiratory health.

When the squash is done, turn the oven heat down to 350 F. We’re not finished with it just yet.
Once the spaghetti squash has cooled off, scrape the flesh into a cast-iron skillet.

Use a wooden spatula to combine all of the ingredients.
Now it’s cheese time! Top the casserole with the buffalo mozzarella and bake for 25–30 minutes.
