Step-By-Step Instructions
The best part of this casserole recipe is that it really could not be any easier to make. Actually, the best part is the incredible flavor. Regardless, you’ll love this hearty vegetable stew.
I recommend that before you begin, you get cheddar cheese and shred it yourself. It melts better when it’s freshly shredded. If you already have a bag of pre-shredded cheddar, you can use that.

When you’re ready to make this slow cooker recipe, simply pour all the ingredients into your Crock Pot at once. Give it a good stir, cover it, and set it to cook on low for three to four hours.
You can use whatever kind of bag of mixed frozen veggies you want. Mine had green beans, corn, carrots, and peas.
There are so many different varieties that you can try, so just pick the ones with your favorite vegetables.
You can also make variations of this slow cooker vegetable stew by using root vegetables like sweet potatoes or by adding white beans and butternut squash.

It’s a tasty vegetarian stew that can be served as a side or main dish.
If you want to make it a vegan recipe, you’ll need to change the type of condensed soup and swap the chicken broth for vegetable broth. You will also want to use vegan cheese to make it a fully meatless meal.
You can also add some meat and make it a beef stew recipe or shred chicken and add it to the pot for a super healthy meal.
Dishes and Optional Ingredients to Serve With the Veggies
- Crusty bread or dinner rolls
- Add some diced bell peppers on top after cooking to add a crunchy topping.
- Sprinkle your favorite fresh herbs right on top.
- Throw on a crispy topping like French Fried onions.




Do you recommend any particular frozen vegetable blend?
Tried this with walmart brand frozen mix and was very dissatisfied.
All I seem to find is typical store veggies with big chunks of broccoli and Cauliflower. The pieces that I’d throw away if working with whole heads of each of above.
Do you recommend putting whole kernel corn into this?
Thank You,

Hi Les,
I bought mine at Publix. They are the Publix brand mixed vegetables. They had carrots, green beans, corn, peas, and lima beans. And then you can add some broccoli to the mix. The bag I bought had whole kernel corn in it, but if you buy a bag that doesn’t have corn you can definitely add it. Hope that helps!
