Step‑by‑Step Instructions for Vegetable Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, lightly grease a 9×13-inch casserole dish with butter or cooking spray to prevent sticking. This ensures your creamy Vegetable Casserole slides right out when served, showcasing its delightful layers and bright colors.
Step 2: Sauté the Onions
In a large pot over medium heat, melt 2 tablespoons of butter. Add a diced yellow onion and sauté for about 5 minutes, stirring occasionally, until the onion is soft and translucent. This step is crucial for building flavor, as it releases the aromatic goodness of the onion into your base for the casserole.
Step 3: Combine the Creamy Base
To the softened onions, stir in a can of condensed cream of mushroom soup, 1 cup of milk, and 1 cup of sour cream. Sprinkle in garlic salt, mustard powder, Italian seasoning, and black pepper to taste. Mix thoroughly and cook for another 2–3 minutes until the mixture is smooth and slightly bubbly. This creamy base is the heart of your Vegetable Casserole.
Step 4: Add the Vegetables
Next, fold in 1 cup of frozen broccoli and 2 cups of frozen mixed vegetables. Allow everything to heat through for about 5 minutes, stirring gently to combine. Then, incorporate 2 whisked eggs and 3 cups of cooked white long grain rice, mixing until everything is evenly distributed. This step ensures a hearty and nutritious dish filled with vibrant colors.
Step 5: Transfer to Casserole Dish
Once your mixture is uniformly combined, carefully pour it into the prepared casserole dish, spreading it evenly. With the base established, sprinkle 1 cup of shredded cheddar cheese on top, allowing it to create a rich, melty layer when baked. This is what brings that satisfying cheesy goodness to your vegetable casserole.
Step 6: Bake with Foil
Cover the casserole dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes, allowing the flavors to meld and the casserole to heat through. Covering the dish will help retain moisture, ensuring your Vegetable Casserole turns out creamy and delicious.
Step 7: Add the Crunchy Topping
After 20 minutes, carefully remove the foil and prepare the crunchy topping. In a small bowl, combine crushed Ritz crackers with 2 tablespoons of melted butter. Sprinkle this mixture evenly over the casserole. Return it to the oven for an additional 10 minutes, until the topping is golden brown and crisp.
Step 8: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for about 5 minutes before serving. This allows the layers to settle, making it easier to serve up portions that showcase the creamy layers of vegetables and rice. Garnish with fresh parsley if desired, and enjoy this delightful Vegetable Casserole with family and friends!
How to Store and Freeze Vegetable Casserole

Creamy Vegetable Casserole Recipe FAQs
What is the best way to select vegetables for the casserole?
Absolutely! When picking vegetables, choose fresh, vibrant ones without dark spots or blemishes. For frozen veggies, opt for those without any ice crystals, as this indicates they've been kept at the right temperature. Seasonal vegetables are always a great choice for best flavor!
How should I store leftover Vegetable Casserole?
Very! Store your leftover Vegetable Casserole in an airtight container in the fridge for up to 3 days. Ensure the casserole is cool before sealing to avoid condensation, which can make it soggy! This makes it perfect for quick reheats throughout the week.
Can I freeze this casserole for later use?
Absolutely! You can freeze the Vegetable Casserole for up to 3 months. To store, use airtight containers or heavy-duty freezer bags. I recommend wrapping it tightly with plastic wrap before placing it in a container to prevent freezer burn. For reheating, thaw in the fridge overnight and bake at 350°F (175°C) until heated through.
What can I do if my casserole turns out too watery?
No worries! If your casserole ends up too watery, mix in a tablespoon or two of cornstarch dissolved in a little water to thicken it up. Another alternative is to pour the mixture into a shallow baking dish, which helps excess moisture evaporate during cooking. Remember, cooking the vegetables less before adding them can also help retain their crunch.
Are there any dietary considerations I should be aware of?
Very! This casserole is meatless and can be easily adapted for different diets. For dairy-free needs, substitute with plant-based milk and cheese alternatives. If anyone has egg allergies, try using a mixture of 1 tablespoon of flaxseed meal with 2.5 tablespoons of water for each egg to act as a binder. Always check labels for any potential allergens!
How long can I prepare this dish in advance?
Definitely! You can assemble the casserole up to 2 days in advance without the topping. Just cover it well and refrigerate. When you’re ready to bake, remove it from the fridge and add the crunchy topping before putting it in the oven. This keeps it fresh and delicious!
