Preheat your oven to 375 degrees Fahrenheit. Spray a 9-by-13-inch baking dish with cooking spray and set aside.
Steam the broccoli and cauliflower together until the broccoli turns bright green and is tender-crisp, about five to seven minutes. Drain well to remove excess moisture.
1 head broccoli, 1 head cauliflower
While they steam, melt the butter in a large skillet. Add the onion and the garlic. Season with salt and pepper. Cook until the onion is soft and translucent, about five minutes.
3 tablespoons unsalted butter, 1 small yellow onion, 2 garlic cloves, 1 teaspoon kosher salt, dash freshly ground black pepper
Whisk in the flour until the onion is coated and you can't see streaks of white. Slowly whisk in the milk and bring the mixture to a simmer. Cook for about one minute.
3 tablespoons all-purpose flour, 2 cups milk
Add the broccoli and cauliflower to the baking dish. Then pour the creamy mixture over the top. Top with cheese and breadcrumbs.
2 cups shredded cheddar cheese, 1/3 cup breadcrumbs
Bake for 25 minutes, uncovered, or until the cheese is bubbling and begins to turn brown.

Milk: I used skim milk for this recipe, but milk with a higher fat content would also work great here.
