Ingredients for Cheesy Broccoli Cauliflower Casserole with Herb Crumble

The star players here are the broccoli and cauliflower florets, providing a hearty base that's rich in vitamins. We’re using sharp cheddar cheese for its robust flavor and Parmesan cheese for a salty kick. The heavy cream makes the sauce irresistibly creamy, while garlic powder, onion powder, and a hint of nutmeg add depth and warmth. The gluten-free bread crumbs combine with butter, parsley, and thyme for a perfectly crispy, aromatic topping.

Tips & Tricks

  • For extra flavor, try roasting the veggies instead of steaming them.
  • Use freshly grated cheese for a smoother sauce — it melts better than pre-shredded options.
  • If you prefer a richer dish, substitute half of the cheddar with Gruyère cheese for a nutty twist.

Serving Suggestions

This casserole pairs wonderfully with a simple green salad dressed in lemon vinaigrette for a fresh contrast. It's also a great side dish for roasted chicken or grilled salmon, adding a comforting, creamy element to your meal.

Frequently Asked Questions

Can I use frozen vegetables?
Yes, just make sure to thaw and drain them well to prevent excess moisture in the casserole.
Is there a dairy-free option?
Try using coconut cream and dairy-free cheeses, though the flavor will vary slightly.

Cheesy Broccoli Cauliflower Casserole with Herb Crumble Recipe Walkthrough

First, preheat your oven to 375°F. This ensures the casserole will bake evenly. While the oven heats, steam the broccoli and cauliflower florets until they’re tender — about 5-7 minutes should do it. You want them soft but not mushy, maintaining a bit of bite.

Next, in a saucepan over medium heat, pour in the heavy cream. As it warms, stir in the sharp cheddar and Parmesan cheeses, followed by the garlic powder, onion powder, nutmeg, and a pinch of salt and pepper. Stir until the cheeses melt and the sauce is smooth and velvety.

Once your sauce is ready, combine it with the cooked broccoli and cauliflower in a large bowl. Make sure everything is well-coated, then transfer the mixture into a greased baking dish.

For the topping, mix the gluten-free bread crumbs with melted butter, parsley, and thyme in a separate bowl. Sprinkle this herb crumble over the casserole, covering it evenly.

Pop the dish into your preheated oven and bake for 20-25 minutes. You'll know it's ready when the top is golden brown and irresistibly crispy. Let it cool for a few minutes before serving to allow the flavors to settle.
