Vegetable Casserole Ingredients

Family dinners and holiday meals in our family always include this cheesy casserole on the menu. Easy to make and loaded with hearty vegetables, rice, and a rich sauce, it’s sure to become a family favorite for your gang, too.

This is ideal for Thanksgiving dinner, Easter, Christmas, or birthday celebrations. It’s also an easy weeknight meal when you add diced ham or serve it along with chicken.

You’ll need:

1 large onion
1 cup Oleo (margarine) or butter, divided in half
1 can of cream of mushroom soup
1 jar of Cheez Whiz
1 cup of Minute Rice
1 (12-ounce) package of frozen California blend vegetables
1 cup of breadcrumbs

Creamy Vegetable Casserole Substitutions And Additions

This versatile and comforting side dish recipe offers a lot of customization options. It’s the perfect way to enjoy your favorite veggies. Here are some good ideas to try:

VEGETABLES: I always like to add a little bit of creativity and make this veggie casserole a little different every time.

You can replace the California blend frozen vegetables with your favorite vegetable mixture or any leftover veggies from your fridge. This would be delicious with green beans, sweet corn, Brussels sprouts, water chestnuts, yellow pepper, or red pepper.

You may need to adjust the baking time if you use fresh vegetables.

MEAT: Add protein to your delicious casserole by adding chunks of leftover chicken breast or diced ham.

BREADCRUMBS: I have various herb breadcrumb mixes I like to rotate through when I’m making this casserole. You could also use crushed Ritz crackers instead of bread crumbs or panko crumbs.

CHEESE: Cheese is also a top choice to elevate this dish. Shredded cheddar cheese or parmesan cheese adds flavor to the casserole crust.

TOPPINGS: Garnishes really add an extra flair to this creamy casserole. You can serve it with French fried onions, bacon bits, sesame seeds, chopped green onions, or just more shredded cheese sprinkled on top.

HERBS: Herbs like fresh thyme, basil, parsley, or rosemary will elevate your casserole with an added aroma. Season with black pepper to your taste.

OLEO: You can use butter in this recipe in place of the Oleo, which is a more old-fashioned product.

CREAM SOUP: You can use another kind of cream soup if you prefer, such as cream of chicken or cream of celery.
