Ingredients

• 4 cups milk
• 2 teaspoons butter
• 1 tablespoon Worcestershire sauce
• 1 cup Italian seasoned bread crumbs
• 1 tablespoon mustard powder
• 2 heads cauliflower
• 1 pinch paprika, or to taste

• 0.5 teaspoon ground black pepper
• 0.5 cup all-purpose flour
• 0.25 cup extra-virgin olive oil

Recipe Instructions

Step 1

Core and cut cauliflower into large florets. Cut broccoli into large florets; peel and quarter broccoli stalks.

Step 2

Bring a large stockpot of water to a boil; add cauliflower and boil until tender but still firm, 8 to 10 minutes. Transfer cauliflower to strainer using a slotted spoon; run under cold water to stop cooking. Add broccoli stalks to stockpot and boil 3 minutes; add broccoli florets to stockpot and boil until stalks and florets are tender but still firm, about 5 minutes more. Transfer broccoli to strainer and run under cold water to stop cooking. Dry cauliflower and broccoli with paper towels and place in prepared baking dish.

Step 3

Melt 1/2 cup butter in saucepan over medium heat. Whisk in flour to form a thick paste. Continue whisking constantly until flour begins to brown, about 4 minutes. Add milk and bring to a boil, whisking constantly, until sauce thickens, 2 to 4 minutes more. Remove sauce from heat; whisk in mustard, Worcestershire sauce, and pepper. Whisk in Cheddar cheese until melted and fully incorporated. Pour cheese sauce over cauliflower and broccoli. Rap baking dish on counter a few times to remove air bubbles.

Step 4

Mix bread crumbs and olive oil together in a small bowl. Top vegetable and sauce mixture with bread crumb mixture. Sprinkle paprika over bread crumb mixture.

Step 5

Bake in the preheated oven until bubbly and golden brown, about 30 minutes.

Step 6

Preheat the oven to 375 degrees F (190 degrees C). Grease a baking dish with 2 teaspoons butter.
