Ingredients

Gather these basic ingredients to make your delicious vegetable casserole:

  • 1 (16 ounce) bag frozen broccoli florets (see Note 1 below)
  • 1 (16 ounce) bag frozen sliced carrots
  • 1 (16 ounce) bag frozen cauliflower florets

Many studies confirm the comparable nutritional benefits of frozen vegetables to fresh varieties, offering a convenient and healthy option.

  • 1 (16 ounce) package Velveeta, sliced (see Note 2 below)
  • 1 roll Ritz crackers, crushed (about 1.5 cups) (see Note 3 below)
  • 1/4 cup (1/2 stick) unsalted butter, melted

Notes & Substitutions

You can easily adjust the types of frozen vegetables. Aim for a total of 9 cups. If using fresh vegetables, blanch them until tender-crisp before use, then drain thoroughly. Substitute Velveeta with a ready-made cheddar cheese sauce or shredded cheddar cheese mixed with a little cream of mushroom soup for a similar creamy texture. For the topping, replace Ritz crackers with plain breadcrumbs, Panko, or a gluten-free cracker alternative.

Equipment

You won’t need many specialized tools for this easy vegetable casserole:

  • 9×13 inch baking dish
  • Large microwave-safe mixing bowl
  • Medium mixing bowl
  • Measuring cups and spoons

Instructions

Follow these simple steps to create your perfect vegetable casserole:

  1. Preheat Oven: First, preheat your oven to 350°F (175°C).
  2. Warm Vegetables: In a large microwave-safe bowl, combine the frozen broccoli, carrots, and cauliflower. Stir them together. Microwave the vegetables uncovered on high power until they are warm throughout, which typically takes about 12 to 15 minutes. This step ensures even cooking in the oven.
  3. Transfer to Dish: Carefully transfer the warm vegetables into your 9×13 inch baking dish. Spread them out evenly across the bottom.
  4. Add Cheese Layer: Evenly arrange the sliced Velveeta cheese over the entire layer of vegetables. The cheese will melt beautifully, creating a rich sauce.
  5. Prepare Topping: In a separate medium bowl, add the crushed Ritz crackers and the melted butter. Toss these together gently until the cracker crumbs are fully coated with butter.
  6. Add Cracker Topping: Sprinkle the buttery cracker mixture evenly over the Velveeta cheese layer in the baking dish. This creates a wonderful crispy crust.
  7. Bake Casserole: Place the baking dish in the preheated oven. Bake for approximately 30 to 45 minutes, or until the cheese is completely melted and bubbly, and the cracker topping turns a beautiful golden brown.
  8. Serve Warm: Remove the classic vegetable casserole from the oven and let it stand for a few minutes before serving. Enjoy your delicious, comforting side dish!

Pro Tips & Troubleshooting

  • Thaw Vegetables: Ensure your frozen vegetables are mostly thawed or warm before baking. This prevents a watery casserole and promotes even cooking.
  • Don’t Over-Microwave: Be careful not to over-microwave the vegetables initially. They should be warm, not mushy.
  • Crispy Topping: For an extra crispy, golden-brown topping, you can briefly broil the casserole for 1-2 minutes at the very end. Watch it carefully to prevent burning.
  • Seasoning: Season the vegetables lightly with salt and pepper after microwaving but before adding the cheese and cracker layers.
  • Prevent Soggy Topping: Do not cover the casserole while baking. This allows the cracker topping to crisp up properly.

Serving, Storage, & Variations

Serve this delightful vegetable casserole warm as a beloved holiday side dish or as an easy addition to any family meal. It pairs perfectly with roasted chicken, ham, or other comfort foods like meatloaf.

Store any leftover casserole in an airtight container in the refrigerator for up to 4 days. For best texture, reheat individual portions in the oven at 350°F (175°C) until warmed through, covering with foil to prevent drying. Microwaving also works, though the topping might lose some crispness. Freezing this casserole is not recommended as it can alter the texture of the vegetables and cheese sauce.

Flavor Variations

  • Different Veggies: Feel free to add other frozen vegetables such as peas, green beans, or corn.
  • Aromatic Boost: Incorporate sautéed diced onions, shallots, or bell peppers with your frozen vegetables.
  • Cheese Please: Experiment with other cheeses like sharp cheddar, Colby Jack, or even a smoked Gouda for different flavor profiles.
  • Herby Topping: Mix fresh or dried herbs like parsley, thyme, or chives into your buttery cracker topping for an aromatic twist.
  • Make It a Main: Transform this side dish into a main course by adding 1-2 cups of cooked shredded chicken or ham to the vegetable layer before baking. This makes a hearty and complete meal.
