    Ingredients for veggie casserole

    You can pick from a wide variety of vegetable combination like carrots, green beans, corn, cauliflower, broccoli, spinach, mushrooms, or any other favorite veggies of your choice.

    Avoid using vegetables (like eggplant, and tomatoes) that release too much water else the veggie casserole may turn out to be runny.

    You will need milk, all-purpose flour, and butter for the white sauce, and some grated cheese for the topping. Garlic and spicy pepper can be used as per taste for enhancing the flavor.

    Yes, you can use frozen vegetables or a mix of fresh and frozen vegetables in a casserole. You can also chop and freeze fresh vegetables and then use them.

    Steps to making a veggie casserole recipe

    The veg casserole can be made in three easy and quick steps. Instant pot cooks the veggies to perfection in just a few minutes.

    The white sauce can be made while the veggies are cooking. Finally, bake the mixed vegetables, sauce, and cheese in a baking dish in the oven.

    How to cook mixed vegetables in instant pot?

    In the instant pot container, add about half a cup of water. I am using 6 qt. instant pot. Add all the vegetables to a steamer basket. Pressure cook the vegetables for zero, yes "zero" minutes.

    As soon as the instant pot comes to full pressure and turns off, do a quick release manually and release all the pressure, but carefully. Quick-release ensures that vegetables are cooked to perfection.

    How to make white sauce?

    While the veggies are cooking in the instant pot, prepare the white sauce on the cooktop. In a pan, heat and melt butter. Optionally add some garlic and green chili paste, chopped ones work well too. Mix well.

    Check out my recipe to make garlic paste at home.

    Add little all-purpose flour and cook for about 30 seconds until it is well incorporated into the butter.

    Add milk, and salt and once it gets bubbly, add some shredded cheese, I like to use cheddar or pepper jack, but you can use cheese of your choice. Once the sauce thickens, turn off the flame.

    How to make vegetable casserole in oven?

    Preheat the oven to 400 °F. Mix the steamed vegetables and white sauce gently and pour into a casserole dish.

    Sprinkle some shredded cheese on top of it, a hand grater comes in handy while grating cheese. I like sharp cheddar cheese, swiss cheese, or pepper-jack but you can use any cheese of your choice.

    Bake the casserole dish in the oven for about 20 minutes until the cheese melts and becomes golden brown.
