Vegetable Au Gratin– a continental delicacy made with mixed vegetables and spinach cheese sauce as a base. Vegetable au gratin or veg au gratin has all the vegetables drowned in white sauce with lots of cheese, its creamy with a crusty top. It can be served with toasted bread.

Baking is fun, you can create so many things with little effort, this particular au gratin is so healthy and tasty that nobody can say no to it. And this can be included easily with any continental menu, this is very simple to make and looks are very tempting to impress anybody.

How To Prep Vegetables For au Gratin

We’ve used fresh beans, carrots, cauliflower, potatoes, and peas. The veggies should all be chopped into approximately the same size so that they cook evenly. You can chop the veggies by hand or use a veggie cutter. The cooking time for each veggie is different and is detailed in the recipe card below. In one big pot of boiling water, we cooked the potatoes, carrots, cauliflower florets, beans, and peas, in that order. They cook evenly and are just right.

How To Make Spinach Cheese Sauce

The base of spinach cheese sauce is béchamel sauce or white sauce. To get the béchamel sauce right, you need to get the mixture of flour, butter and milk exactly right. So make sure you refer to the recipe card and measure these ingredients out. It’s important to cook the flour for a minute or two in butter so that the flour is not raw anymore. Before you add milk Should do the sniff test of the roux (flour and butter) should smell slightly nutty.

The only pressure point with a béchamel sauce is to keep it lump-free which can sometimes be difficult to achieve. The idea is to incorporate milk in a steady stream as you whisk it with the flour. Do this in batches so that milk gets fully incorporated before you add the next batch. This will ensure you have a lump-free, smooth sauce. We love classic French flavours so some garlic, minced onions, rosemary and nutmeg also go in the sauce. Later we added chopped spinach and lots of shredded cheese to give a smooth creamy green look.

The Cheese Layer

The veggies and spinach cheese sauce are creamy and smooth while the top layer is cheesy and crunchy. To get that golden brown top, there are two steps:

  • The cheese layer: there’s a layer of cheese that goes on top of veggies in spinach and cheese sauce. I’ve made this layer with grated processed cheese and parmesan shavings. 
  • The layer of bread crumbs: I’ve used bread crumbs they get super crisp and take on a beautiful colour when baked. If you don’t have Bread crumbs you can Toast bread and make bread crumbs by grinding them in a mixer. Generously sprinkle the breadcrumbs on top of the cheese to get that golden baked layer on top of the au gratin!
