How to Prepare the Perfect Vegetable Casserole: Step-by-Step Guide

This recipe comes together in about an hour, making it ideal for weeknight dinners or when you’re feeding a crowd of 12.
First, if using frozen veggies, microwave the 16 ounces each of broccoli, carrots, and cauliflower in a large microwave-safe bowl on high for 12 to 15 minutes until they’re warm and ready to go. If you prefer fresh, blanch them in boiling water until tender, then drain and dry to get about 9 cups total. This step ensures your vegetables are just the right texture without becoming mushy.
Next, transfer the warmed vegetables to a 9×13 inch baking dish and spread them out evenly. Layer on the 16 ounces of sliced cheese, like Velveeta or cheddar, for that gooey, melty goodness. In a separate bowl, mix the crushed crackers with 1/4 cup of melted butter until well combined, then sprinkle this topping over the cheese layer.
Now, pop the dish into your preheated oven and bake for 30 to 45 minutes, until the cheese is fully melted and the topping turns a beautiful golden brown. Once it’s done, let it cool for a few minutes before serving to avoid any burns it’s worth the wait for that perfect bite.
