Before diving into cooking, it's essential to set up your space for a smooth experience. Start by gathering all your 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

Sauté the onions
In a large pot over medium heat, melt the butter and add the diced onions. Sauté for about 5 minutes until they are softened and fragrant. This step doesn’t just bring out the flavor of the onions; it sets a lovely aromatic foundation for your vegetable casserole. For more guidance on sautéing, check out this useful guide.
Create the creamy base
Next, let’s build that luscious creamy base. Stir in the cream of mushroom soup, milk, sour cream, and the seasonings: garlic salt, mustard powder, Italian seasoning, and a pinch of pepper. Blend thoroughly until well combined. Then, add 1 cup of the shredded cheddar cheese, stirring until it melts into that wonderful gooey mixture.
Add veggies and rice
Now it's time for the star players! Add the frozen broccoli and mixed vegetables to the creamy concoction, letting them heat through just enough. Once they’re warmed, remove the pot from the heat and let it cool slightly. Then, gently fold in the whisked eggs and cooked rice until well mixed. This mixture is the heart of your vegetable casserole—a beautiful medley of flavor, nutrition, and comfort.
Assemble and bake the casserole
Transfer the mixture into your lightly greased casserole dish, smoothing it to ensure even cooking. Top it off with the remaining cheddar cheese. Cover the dish with foil and bake for 20 minutes. Meanwhile, combine the crushed Ritz crackers with the melted butter in a bowl. After the initial baking, remove the foil and sprinkle the cracker mixture on top. Bake uncovered for an additional 10 minutes until golden and bubbly.
Now, your vegetable casserole is ready! Let it cool slightly before serving. This dish not only makes a delightful meal but also fills your home with a warm, inviting aroma. Enjoy!

FAQs about Vegetable Casserole
Can I use fresh vegetables instead of frozen?
Absolutely! While frozen vegetables are convenient and often retain their nutrients, you can use fresh ones to add a delightful crunch and flavor to your vegetable casserole. Just be sure to steam or cook them until they're about 90% done before mixing them in. This helps keep them tender and prevents them from becoming mushy during baking.
How can I make this dish vegetarian or vegan?
To make this vegetable casserole vegetarian, simply replace the sour cream with a plant-based alternative like coconut cream or cashew cream. For a vegan option, use a dairy-free cream soup alternative and omit the eggs; you can replace them with a flaxseed or chia seed mixture (1 tablespoon of seeds mixed with 2.5 tablespoons of water equals one egg).
What can I serve this casserole with?
This comforting dish pairs wonderfully with a variety of sides! Consider serving it with a fresh green salad, crusty bread, or roasted vegetables for a balanced meal. You can also enjoy it with a side of protein like grilled chicken or turkey bacon to make it a heartier option.
