Ingredients:

1 small yellow onion (finely diced)

1 tablespoon butter

10.5 oz. condensed cream of mushroom Soup

½ cup milk

½ cup sour cream

8 oz. shredded cheddar cheese (divided)

2 heaping cups frozen broccoli

3 cups frozen mixed vegetables

2 large eggs (whisked)

2 cups cooked rice (I use white long grain rice. See notes.)

½ teaspoon garlic salt

½ teaspoon salt

½ teaspoon mustard powder

½ teaspoon Italian seasoning

¼ teaspoon pepper

Preparing Your Casserole: Step-by-Step

This recipe is designed to be straightforward, even for beginner cooks. The use of frozen vegetables means minimal prep work, and the assembly is quick and easy. The baking time allows the flavors to meld and the casserole to become wonderfully tender and bubbly.

1. Sauté the Aromatics: Begin by preparing your flavor base. In a medium skillet, melt the tablespoon of butter over medium heat. Once the butter is melted and slightly shimmering, add the finely diced yellow onion. Cook the onion, stirring occasionally, until it becomes translucent and slightly softened, which usually takes about 5-7 minutes. You don’t want the onions to brown significantly; we’re just looking to release their sweet flavor. This step is crucial for building depth in the casserole.

2. Create the Creamy Sauce: In a large mixing bowl, combine the condensed cream of mushroom soup, ½ cup of milk, and ½ cup of sour cream. Whisk these ingredients together until they are smooth and well incorporated. This mixture will form the creamy, luscious sauce that binds all the ingredients in the casserole. Next, stir in half of the shredded cheddar cheese (4 oz.) into the creamy mixture. Reserve the remaining 4 oz. of cheese for the topping.

3. Incorporate the Vegetables and Rice: Add the two heaping cups of frozen broccoli and three cups of frozen mixed vegetables directly into the large mixing bowl with the creamy sauce. Don’t worry about thawing the vegetables; they will cook beautifully in the oven. Next, gently fold in the two cups of cooked rice. Ensure that all the ingredients are evenly distributed within the creamy mixture. This is where the bulk of the casserole comes from.

4. Season and Bind: Now it’s time to add the seasonings and bind everything together. Stir in the two large, whisked eggs. The eggs act as a binder, helping to hold the casserole together as it bakes and adding a touch of richness. Next, add the ½ teaspoon of garlic salt, ½ teaspoon of salt, ½ teaspoon of mustard powder, ½ teaspoon of Italian seasoning, and ¼ teaspoon of pepper. Mix everything gently until all the ingredients are thoroughly combined. Taste a tiny bit of the mixture (raw egg notwithstanding, just for seasoning balance) and adjust salt and pepper if you feel it needs it.

5. Assemble and Bake: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish or a similar sized casserole dish. Pour the entire mixture from the bowl into the prepared baking dish, spreading it evenly. Sprinkle the remaining 4 oz. of shredded cheddar cheese evenly over the top of the casserole. This creates a wonderful cheesy crust as it bakes. Cover the baking dish tightly with aluminum foil. Bake for 30 minutes. After 30 minutes, carefully remove the foil and continue baking for another 20-25 minutes, or until the casserole is hot, bubbly, and the cheese on top is melted and golden brown. The foil helps to steam the vegetables and cook the inside without drying out the top too quickly. Removing it at the end allows for that irresistible cheesy, browned topping.

Notes on Rice:

For this casserole, I find that plain white long-grain rice works best. It has a neutral flavor that doesn’t compete with the vegetables and creamy sauce, and its texture holds up well in the casserole. To prepare it, simply cook your rice according to package directions, ensuring it’s fully cooked before adding it to the casserole mixture. You’ll need about 2 cups of cooked rice. If you have leftover rice from another meal, that’s perfect!

Enjoy this wonderfully comforting and easy-to-make vegetable casserole. It’s a dish that truly warms the soul.

Frequently Asked Questions:

Can I make this casserole ahead of time?

Absolutely! This Vegetable Casserole is an excellent candidate for make-ahead meals. You can assemble it completely, cover it tightly, and refrigerate it for up to 24 hours before baking. You might need to add a few extra minutes to the baking time if cooking directly from the refrigerator.

What are some good vegetable substitutions?

The beauty of this casserole is its adaptability! Feel free to substitute any vegetables you have on hand or prefer. Broccoli, cauliflower, zucchini, bell peppers, green beans, corn, and spinach are all fantastic additions. Just ensure they are cut into bite-sized pieces and consider pre-cooking any harder vegetables like large chunks of broccoli or cauliflower if you want them extra tender.

How can I make this casserole richer and more decadent?

To elevate the richness, consider adding a layer of crumbled cooked beef bacon or sausage to the casserole, or stir in some grated Parmesan cheese into the sauce. For an extra creamy texture, you can also incorporate a dollop of sour cream or a touch of heavy cream into the sauce before baking.
