How to make cheesy vegetable bake

  1. Roast the vegetables: Slice the cauliflower into florets, halve the mushrooms (or slice if using large mushrooms), chop the peppers and onions. Place all the vegetables in a roasting dish and drizzle with olive oil. Season with salt and pepper and toss to coat the vegetables in the seasoning. Place in a hot oven and roast for 30 minutes until golden brown.
  2. Combine with sauce and bake: Pour the cheese sauce over the vegetables, top with the mozzarella and Parmesan then place back in the oven and bake until bubbling and golden on top. Remove from the oven, allow to rest for 5 minutes then serve.

Can I make this ahead?

Yes! The vegetables can be roasted and combined with the sauce then refrigerated for up to 3 days before baking with the cheese. You could freeze the bake too (unbaked). Bake from frozen until hot throughout.

  1. This, and variations on this recipe, have become a favourite in our household.
    If using broccoli I don’t roast it with the other veg, I just put it into the dish raw. If you want the broccoli a bit softer microwaving or steaming it for a short time before works better than roasting it.
    If you want to add some meat I recommend chunks of chorizo which flavours the cheese, or smoked sausage also works very well.

      1. Do you mean up to the point of roasting the vegetables or can you refrigerate the roasted vegetables with the cheese sauce on overnight and finish cooking the next day?

  2. I make this all the time and it’s SO good. Everyone always asks me for the recipe, which is thankfully quite simple. A real winner.

      1. This is one of my favourite recipes. I modify it to the tastes of whomever is eating, and it’s the only way to get vegetables into a few of them.

  3. This was just the ticket on a comfort food mandatory night. The vegetarians loved it as a main and the omnivores as a side dish. So simple, and so adaptable too. Thanks so much!

  4. Hi Alida,

    Like as you, most of all experience the same while opening the fridge, but it is really good that you can find out the way how to make it delectable!

    We will give it a try & if it meets to our standard, we will include in our club restaurant list.

    Thank you for sharing here.
