Instructions
Preheat oven to 400˚F. Drizzle a little olive oil on the bottom of a square baking dish; spread it around and set aside.
In a large skillet, bring 1/2 inch of salted water to a boil. Add the broccoli and cauliflower; cover and cook over high heat until crisp-tender, about 4 minutes. Drain the vegetables in a colander and set aside.
Wipe out the skillet, add 2 tablespoons olive oil, and heat over medium-high heat. Add onions and cook for 2 to 3 minutes or until softened.
Stir in the minced garlic and continue to stir and cook for 1 minute. Add broccoli and cauliflower to the skillet. Season with salt and pepper and continue to cook for about 2 minutes, or until lightly golden.
Remove from heat and transfer the vegetables to the baking dish; set aside.
Wipe the skillet and add 1 tablespoon olive oil, 3/4 cup shredded cheddar cheese, cornstarch, evaporated milk, mustard, salt, pepper, and paprika.
Cook over low heat, stirring constantly with a whisk, until melted and thickened, about 2 minutes.
Pour the cheese sauce over the broccoli and cauliflower; stir to combine. Sprinkle the remaining cheeses over the top.
Bake for 20 minutes or until lightly browned and bubbly.
Remove from oven and let stand 5 to 8 minutes, then serve.
Notes
Prep ahead. This casserole can be assembled up to one day in advance, then baked just before serving.
Use different vegetables. Swap out the cauliflower for another veggie. Brussels sprouts and green beans will work.
Fork tender veggies. Aim for crunchy, not soggy, veggies in the first steaming step.
Control the flame. For a velvety cheese sauce, keep your heat low and keep stirring.
Cheese options. Mix up your cheese game – consider a mix of cheddar and gruyere or a dash of parmesan.
Want to make it a main course? Throw in some cooked chicken, crispy bacon, or even canned tuna.
Season. Don't forget to season your veggies when frying them.
