Test Kitchen Tip

Instead of using processed cheese, make a sauce with strong-flavored cheeses like Gouda and Emmental.


Preheat oven to 375°.

Blanch broccoli and cauliflower in a pot of boiling salted water, 3 minutes. Drain and immediately shock in ice water; set aside.

Combine crumbs with melted butter in a bowl until coated, then season with salt and pepper.

Melt 3 Tbsp. butter in a large saucepan over medium heat. Add shallots and caraway seeds; cook until seeds are toasted, 3 minutes.

Whisk in flour, coating shallots; cook 1 minute. Whisk in milk and Dijon, cooking until sauce slightly thickens, 8 minutes (do not boil). Add Gouda; stir until melted. Add Emmental; stir until melted. Season sauce with salt and pepper.

Stir broccoli, cauliflower, and rice into sauce. Transfer mixture to a 2-quart baking dish.

Sprinkle crumb topping over casserole, and bake casserole until bubbly, about 35 minutes. Let casserole rest 10 minutes before serving.


After blanching the vegetables, shock in ice water to stop cooking and retain the broccoli’s color.


Stir the rice and vegetables into the cheese sauce to coat thoroughly before transferring to baking dish.
