Vegetable Bake is a medley of oven-baked vegetables in a creamy white sauce. It is an all-time classic continental style vegetarian main course. The crusty layer of cheese on top make baked vegetable in white sauce my absolute favorite.

Vegetable Bake Nostalgia
Creamy Baked Vegetables was the only continental dish in my Indian household while I was growing up.
In other words, vegetable bake in a thick white sauce was the only continental dish in my mother’s cooking repertoire.
She got the recipe from an American cookbook and changed it to suit our Indian tastebuds.
Hence, the dish holds a special place in my food memoirs.
Over the years I have made my additions and subtractions to the recipe, like regular béchamel sauce is been replaced with whole wheat white sauce. And off-course more of vegetables and cheese is added.

What You Need To Make Vegetable Bake
There are three key components in the making of baked vegetables.
creamy white sauce
sauteed vegetables
crusty topping

1) Creamy White Sauce: This is my multi-purpose whole wheat white sauce for everything. From pasta, creamy mushroom to vegetarian casseroles, I use it for all.
The USP of this white sauce is it does not have any cream or all-purpose flour. It is made with whole wheat flour and milk.
The first step in the making of baked vegetable casserole is the white sauce. The sauce only adds creaminess and flavor to the vegetables.
2) Sauteed Vegetables: The best part of this vegetarian casserole is the truckload of veggies. It is one of those fridge forage meals where you can use all the leftover vegetables.
A few vegetables that work well in this baked casserole:
- zucchini
- mushrooms
- green beans
- cauliflower or broccoli
- pumpkin or squash
- potato or sweet potato
- baby corn or sweet corn
- bell peppers or capsicum
The second step in this recipe is to saute vegetables. Sauteeing makes them crunchy and when baked they do not leech water.
Hence, it is highly recommended to saute vegetables before combining them in the white sauce.
3) Crusty Topping: The most delicious part of a vegetable bake is the golden, cheesy, crusty layer on top. And that my friend, you can achieve by adding a generous layer of cheese.
I use a mix of cheddar and parmesan for the topping. You can combine bread crumbs and cheese to make the top layer more crusty.
This is the third and the final step before baking the casserole.

Serving Suggestions
To serve vegetable bake as a main-course you can complement it with focaccia bread, any other artisanal bread, a bowl of soup, roasted potatoes, or a hearty salad.
Vegetable Casserole can also work as a side dish for steak or meat dinners.

Ohh yes. If you want to make this vegetarian casserole more hearty, go ahead, and add – shredded chicken, roasted chicken, bacon, ham, salami, or even shrimps. The meat should be cooked like vegetables before baking.
