Italian Cauliflower al Forno

Italian Cauliflower al Forno

I’ve always loved cauliflower — it’s one of those vegetables that doesn’t get nearly enough credit. Too often it’s overlooked, but with a little Italian flair, it turns into something truly special. This Cauliflower al Forno is proof that simple ingredients can make magic. Roasted until golden, then baked in layers of rich marinara, creamy béchamel, and melted cheese, it’s cozy, comforting, and completely irresistible. Whether you serve it as a side or a vegetarian main, this dish will make anyone rethink how delicious cauliflower can be.

Things to know about this Italian Cauliflower al Forno

  • Make ahead: You can roast the cauliflower and even assemble the dish a day in advance. Just cover and refrigerate, then bake when ready to serve.

  • Reheating: Warm leftovers in the oven at 350°F until bubbly, or reheat individual portions in the air fryer for a crisp top.

  • Serving idea: Pair it with a simple green salad, crusty bread, or even over a scoop of creamy polenta for a full meal.

  • Storage: Keeps well up to 3 days in the fridge — the flavors get even better as they mingle.

  • Variations

    • Add Italian sausage: Brown mild or spicy Italian sausage and scatter it over the roasted cauliflower before baking for extra heartiness.

    • Use other veggies: Try mixing in roasted zucchini, bell peppers, or mushrooms for more texture and flavor.

    • Make it spicy: Add a pinch of red pepper flakes to your Easy Marinara Sauce for a little kick.

    • Go cheesy: Add a layer of ricotta or burrata before topping with mozzarella for an extra creamy version.

    • Lighter option: Skip the béchamel and just use Easy Marinara Sauce — it’s still delicious and a bit lighter.
