Deliciously cheesy rice and vegetable casserole. A great go to casserole dish to feed a crowd! You can’t go wrong with this classic favorite vegetable side dish.
The week before Easter years ago, I did a test run on this creamy vegetable and rice casserole that I planned to make.
It has since become a staple recipe in our house, and I make it often throughout the year!
It’s one of my favorite vegetarian comfort food recipes along with this creamy vegetable soup and broccoli cheese soup.
This casserole has all the amazing flavor of casseroles I used to make, but uses more wholesome ingredients.
Since first making this recipe, it has now become my go to whenever I am asked to bring a dish to a meal.
It makes a huge amount and everyone asks for seconds!
Everyone always raves about the flavor, and there are rarely any leftovers!
How to make rice and vegetable casserole
First, you will start with diced up garlic, onion, and carrots as a base.
I love tons of fresh garlic and onion, and this casserole is so big that we use lots of it to add flavor.
Carrots are the only fresh vegetable that you will need to chop, everything else is just dump it in from the freezer.
So simple!
While these are cooking, you will measure 3 cups of dry instant brown rice and cook it according to package instructions.
If you want to use a rice cooker with normal rice, just adjust for serving sizes accordingly.
You will need a very large skillet for this recipe.
The one I am using for this recipe is called a Jumbo Cooker, which I purchased from Walmart.
I am now on my 3rd Jumbo Cooker in the last 10 years, and I can tell you that it is one of my most used kitchen tools!
It isn’t expensive and is my go to for cooking so many meals.
I highly recommend investing in one!
If you don’t have a big one like this, the last step of mixing the casserole together can just be done in your baking dish.
Once the carrot/onion/garlic mixture cooks down a bit, you will add in the cream of mushroom soup, frozen peas, frozen broccoli, 1 ½ cups of freshly grated parmesan, and 1 cup of freshly grated sharp cheddar cheese.
It’s very important to not skip the step of grating the cheese fresh from a block.
This adds tons of flavor, and it definitely will not be the same if you just buy packaged pre shredded cheese.
Just trust me on this!
Freshly grated cheese is better than pre grated cheese any day.
Once your mixture heats up, add in the cooked rice and the chopped up fresh parsley and stir until everything is all mixed up.
Your skillet should look like this – all creamy, cheesy, and ready for the oven!
Taste a bit and see if you want to adjust the salt or pepper if necessary.
After that it’s ready to bake!
Next up, transfer your casserole to a large 13 X 9 casserole dish.
This makes a huge amount, so be sure to use a big dish, as anything smaller will not fit it all.
This casserole will easily feed 10 or more people as a side dish, it really makes a ton!
Top your casserole with the remaining 1 cup each of sharp cheddar and parmesan cheese.
Bake at 400 degrees for 10 – 15 minutes, or until the cheese is bubbly and beginning to brown.
That’s when you can tell that it’s ready to eat!
If you want, towards the end of cook time you can broil the casserole for a minute or two to really get that cheese nice and brown.
I love to do this!
Those browned cheesy bits are the best.
Just a few minutes of broiling will get those delicious crispy edges that everyone loves.
I made this tonight for dinner. My teenage daughter, who turns her nose up at everything, LOVED IT. in fact she made sure I kept the pin and said to rate it 5 stars – Tammi
This serves 6 – 8 people as a main dish, and way more as a side.
Perfect for large gatherings, and I’ve even made it as a Thanksgiving side dish before!
Whether you just want a great side dish, or something vegetarian friendly for everyone to enjoy, this rice and vegetable casserole is it.
I have made this countless times over the years and it comes out perfect every time.
It’s my signature casserole dish and I want your family to enjoy it as much as we do!

The problems people seem to be having with proportions are because they haven’t taken into account the different yields of instant rice and traditional rice. For instant rice, 1 cup dry yields 2 cups cooked. For traditional rice, 1 cup dry yields 3 cups cooked. To get the right proportions with traditional rice you only need 2 cups of dry rice. It works great once you realize this and the amounts of stuff are perfect. I added some cubed and cooked chicken thighs and the family liked this.

I’ve made a half recipe of this twice and it’s delicious. I generally use 2 cups frozen mixed veg and 1 c frozen broccoli because that’s what I have on hand. I also throw a can of drained chickpeas in for protein and we eat this as a main dish! Amazing! Thank you!
