    This post was first published in January 2016 and has been updated with new photos and an improved recipe.

    One of my first ever cooking classes at school was learning how to make an apple crumble.  The first week we made the crumble, the second week we made the filling and finally, in the third week, we put it altogether.  No wonder I hated cooking if I thought it took three weeks to make an apple crumble!  

    Well, luckily times have changed and I thought I'd take a little trip down crumble memory lane, here is my savory roasted vegetable crumble, which I promise will not take three weeks to make!

    It packs in loads of seasonal roasted veggies, and is covered in a rich cheese sauce and topped with a crunchy parmesan topping.  It makes for a great veggie side dish for the holidays and is hearty enough to serve up as a main. It's perfect to serve up as part of a weekend feast and the leftovers are ideal for an easy weeknight meal.

    Making the perfect cheese sauce

    The cheese sauce in this vegetable crumble is silky smooth and it is dead easy to make! Rather than having a floury base, I have used a stock base meaning it is less stodgy than usual.  I came across this when cooking Heston Blumenthal's Mac & Cheese, which you should definitely make! It's such a nicer way of making a rich sauce with zero chance that it will turn out lumpy!

    Frequently Asked Questions

    Can you make it ahead of time?

    Yes! This is a great make ahead side dish. You can make the whole dish the night before and keep it covered in the fridge until you are ready to cook it. Leftovers will keep well for 4 to 5 days and can be reheated in the oven at 350F/180c for 20 minutes until warmed through.

    Can you add other veggies?

    This is a great dish to incorporate all of your favorite vegetables, and any that you have laying around in the fridge! Any kinds of squash work great in this dish. If there are any veggies I've included that you don't like, just swap them out!

    What size dish do you need to cook the crumble?

    I used a 13.5 x 9.5 inch glass casserole dish for this recipe and one like this will work well. This will make enough for eight servings and you can easily half it if you prefer, although the leftovers do taste delicious!

    Recipe Notes and Tips

    • I roasted the vegetables for about 30 minutes so that they still have a good amount of texture. If you prefer a softer crumble filling, just roast them to your preference.
    • I didn't peel any of the veggies other than the carrots as it helps to give the crumble a nice texture. Feel free to peel if you prefer!
    • I've made this crumble with both pre grated and freshly grated cheese. Freshly grated is a bit more effort, but the flavor is much richer and fresher.
    • To get the top nice and golden brown, pop it under the broiler for 5 minutes just before serving.

    Ingredients

    For the veg filling

    • 2 tablespoons olive oil
    • 3 tablespoons Italian seasoning
    • 1 teaspoon salt
    • 1 teaspoon pepper
    • 2 carrots
    • 2 onions
    • 1 eggplant
    • 1 yellow pepper
    • 1 orange pepper
    • 1 leek
    • 1 zucchini
    • 8 ounces cremini mushrooms (mini portobellos) (227g)
    • 5 garlic cloves
    • shredded cheese for topping

    For the crumble

    • 1 cup plain flour (120g)
    • 1 stick softened butter cubed (½ cup / 4oz/ 110g)
    • ¼ cup grated parmesan (60g)

    For the cheese sauce

    • 2 cups vegetable stock (500ml)
    • 1 ¼ cups strong cheddar (5 oz / 160g)
    • 2 tbsp cornstarch (cornflour in the UK)

    Instructions

    • Pre-heat the oven to 220º.
    • In a large bowl, pour in the oil and add the herbs and salt and pepper. Chop up the veg into large chunks and peel the garlic cloves.  Put all of the veg, along with the garlic into the oil and herbs and mix well so that all of the veg is coated.
    • Spread out on a baking tray and pop in the oven for 30 minutes, until the edges of the veg are browning.
    • While you are waiting for the veg, you can make the crumble.  Put all the ingredients in to a large bowl and rub the butter in with your hands.  After about 10 minutes you should have a breadcrumb like consistency. Leave to one side.
    • Once the veg is done, take out of the oven and transfer into a large oven proof dish and leave to one side.
    • Turn the oven down to 180º.
    • Finely grate the cheddar, then add the cornstarch to it.  Mix well with your hands so that the strands of cheese are covered.  
    • Over a medium flame, heat the stock, once warm add a handful of grated cheese and stir until it has dissolved, continue until you have used all of the cheese and you have a shiny sauce.
    • Place the roasted vegetables into an oven proof dish (I used a 13.5 x 9.5 inch glass casserole dish)
    • Pour the sauce over the vegetables and then top with the crumble.  Sprinkle over a little black pepper and pop in the oven for 15 minutes.  Finish off under the broiler to brown the top for a couple of minutes before serving.

    • I roasted the vegetables for about 30 minutes so that they still have a good amount of texture. If you prefer a softer crumble filling, just roast them to your preference.
