Cheesy Mixed Vegetable Casserole Recipe
Cheesy mixed vegetable casserole is a classic side dish that is easy and delicious.
This is a quick and delicious mixed vegetable casserole even the pickiest non-vegetable eaters will gobble up.
I don’t make any complicated recipes especially during the week. Use frozen mixed vegetables, store bought shredded cheese and topped with Ritz crackers for an easy side dish.
This is a good recipe to use up any leftovers. I use whatever leftover cheese from other meals. You could also use leftover vegetables.
Who doesn’t like cheese and crackers which is in the vegetable casserole.

All you need is a bag of frozen mixed vegetables thawed in the microwave in a casserole dish. Then you are going to make a roux which is simply butter and flour to thicken the cheese sauce.
A roux is a mixture of butter and flour used to thicken sauces. It has an equal ratio of fat to flour. Besides butter, other fats can be used.

How To Make A Roux
To start the roux, melt two tablespoons of butter in a saucepan. Then add two tablespoons of flour. I used whole wheat flour. It’s what I had on hand. All purpose flour is the better choice. Use what is in your pantry.
Stir until mixture begins to bubble. You want to cook out the raw flour taste.

Then add salt and pepper to taste. I just sprinkle some in. Not too much. Then add 1 cup of milk. I use 2% milk.

Stir continually until mixture comes to a slow boil. Keep stirring or you will have scalded milk in the bottom of your pan. Yes, I know I have left the milk cooking on the stove. Live and learn. Then start over. Just kidding.
Then add the shredded cheddar cheese. Stir till the cheese is melted.

See how pretty it looks. Tastes wonderful, too.
Pour this cheese sauce over your mixed vegetables that you already thawed in the casserole dish. Add crushed Ritz crackers to the top. Oh, go ahead and use lots of crackers.
Then place in a preheated oven to 350℉ and let bake for 30 minutes.

There you have a tasty side dish. I served mine with baked bbq chicken for this meal. I never seem to have leftovers with mixed vegetable casserole. I am so glad to have found a vegetable dish that everyone loves. Yes, everyone. Even my picky eaters.
If you love casseroles, you should try this sweet potato casserole. Absolutely delicious!
