Mixed Vegetable Casserole

March 7, 2013Teresa

Mixed Vegetable Casserole is a comforting side dish that’s great to make up for company, potlucks, or holiday dinners. It’s fairly easy to put together and it has a sumptuous taste. You can use almost any kind of frozen veggie combinations.

The original recipe called for canned mixed vegetables but I never buy those so I’ve always used frozen veggies instead. I’ve used lots of different combinations including stir-fry type frozen veggies and no matter the combination everything turns out great.

If you need to clean out your refrigerator this is a great recipe to do that with! If you need to use up garden produce, again, this is a great recipe to use up all that extra zucchini, tomatoes, squash, and any other veggies you need to use so they don’t go to waste. You almost can’t kill this recipe. Any combination of veggies will work. If you want to have a lively color add diced red pepper. Leeks, garlic, and mushrooms are other veggies you can include for a richer, fuller taste.

I got this recipe from Lynda Jackson, a coworker of mine when we both worked at Dallas Baptist University. She had been a pastor’s wife for years and she could sure cook! During the years I worked at Dallas Baptist trying to get my kids through college, Lynda was known as the premiere teacher for the Portfolio class where adult students could gain classroom credit for work experience.

In order to get credit for that class the student had to write petitions showing why they had sufficient “book knowledge” in a certain subject citing textbooks that actually covered a particular petition’s topic. In other words, to gain credit you had to prove you had learned the theory behind the textbooks in addition to simple work experience. Lynda gave me a lot of sage advice during the time I took the class.

I was one of the few students who achieved a full 33 credit hours taking the Portfolio class during the shortened summer term of 9 weeks (rather than 15). (Yes, I’m an over-achiever). 🙂 Even though Lynda wasn’t the teacher for my particular section, she provided a lot of counsel that helped me along the way to getting complete credit for each of my petitions. Taking that summer class provided enough credits as if I’d worked the whole year!

While we worked together at DBU, Lynda gave me several wonderful recipes and this is one of them. This Mixed Vegetable Casserole has lots of veggies in a creamy sauce of cheddar cheese, sour cream, and cream of celery soup. Then it’s topped with buttered Ritz cracker crumbs. It’s spectacular.

It’s also quick and easy. I don’t even bother to pre-cook the veggies. I just mix them with all the other ingredients and plop them into the casserole dish and bake. Voila! Out comes one of the most delicious casseroles you will ever eat!

When I initially posted this recipe in March 2013, I made it for someone I was taking a meal to. Since the casserole was baked in a foil pan, the light didn’t show it well. Plus, I was still using an iPhone for a camera so the pictures weren’t as sharp as I would have liked.

I recently remade this recipe (October 2016) for a potluck at our church where I was bringing several side dishes including Roasted Italian Tomatoes. I froze the leftovers and served them again about a month later. It’s truly a tasty and versatile casserole that’s an excellent choice for the holidays. I highly recommend it.

NOTE: Ritz crackers has reduced the amount of their boxes from 16 ounces to 13 ounces. You may need to use 1 1/3 sleeves of crackers to get the same amount as the original recipe.

NOTE: Even though this mixture seems dry before you make it, avoid the temptation of adding milk or other ingredients to make it creamier. The cheese melts with the soup and the texture becomes deliciously creamy while baking.

    Can this be made a day ahead? If so, would you wait to add topping? Thanks!

      Hi, Amy. I’ve actually made up the casserole but not baked it before the next day. (Yes, I would wait to add the topping right before baking.) I don’t know if I would bake it ahead and then reheat it. I think that would overcook the veggies.

    How would I convert this recipe for the slow cooker or crock pot?

    1. Teresa

      October 31, 2019 at 7:38 am

      Hi, Dorothea. I would do it this way: Mix the ingredients as recommended and put into a crockpot that’s been sprayed with cooking spray. Cook on a high heat for about 2 to 3 hours. It should be bubbly but not boiling. Add the topping and heat through. That part will probably take about 20 to 30 minutes. Then change heat setting to “keep warm” until needed to serve.

    Did you add water to the cream of celery soup before adding it to the mixture?

      Hi, Bev. No water added.

    Delicious and so easy. Used Panko breadcrumbs instead of crackers. Husband loved it.

      Hi, Karen. So glad you and hubby loved this easy recipe. We’ve always enjoyed it too. I think Panko crumbs would make it perfect!

    Loved this, I only made two slight changes. I used soya sauce in place of the salt and “Durkee’s” french fried onions(the kind you use in green bean casserole). My frozen veg of choice was whole green beans, wax beans and carrots. Definitely a keeper, thank you.
