Mediterranean 30-Minute Cheesy Spaghetti Squash Casserole Magic
This Mediterranean 30-Minute Cheesy Spaghetti Squash Casserole Magic is proof that comfort food does not have to be heavy or time-consuming. It takes the cozy appeal of a cheesy baked casserole and gives it a lighter Mediterranean touch using olive oil, herbs, vegetables, and spaghetti squash instead of pasta. The result is rich, satisfying, and surprisingly fresh.
Spaghetti squash is the quiet hero here. When cooked, it separates into tender strands that soak up flavor beautifully. Combined with cheese, herbs, and a quick stovetop sauce, it turns into a dish that feels indulgent but still balanced. This casserole works well as a weeknight dinner, a meal-prep option, or a crowd-pleasing side dish.
