Cheesy Broccoli and Cauliflower Gratin

Instructions

Step 1: Prepare the Vegetables

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Blanch the Veggies: In a large pot of boiling salted water, add the broccoli and cauliflower florets. Blanch for about 3-4 minutes until just tender but still crisp. Drain and transfer to an ice bath to stop the cooking process. Once cooled, drain again and set aside.

Step 2: Make the Cheese Sauce

1. Melt the Butter: In a medium saucepan, melt the butter over medium heat.
2. Add Flour: Whisk in the flour and cook for about 1-2 minutes, stirring constantly, until it forms a roux and turns slightly golden.
3. Add Milk: Gradually whisk in the milk, ensuring there are no lumps. Continue to cook, stirring frequently, until the sauce thickens (about 5-7 minutes).
4. Season the Sauce: Stir in garlic powder, onion powder, Dijon mustard (if using), salt, and pepper. Remove from heat and mix in 1 cup of shredded cheddar cheese until melted and smooth.

Step 3: Assemble the Gratin

1. Combine Veggies and Sauce: In a large mixing bowl, combine the blanched broccoli and cauliflower with the cheese sauce, mixing until the vegetables are well coated.
2. Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish, spreading it evenly.

Step 4: Add Toppings

1. Top with Cheese and Breadcrumbs: Sprinkle the remaining ½ cup of shredded cheddar cheese and the grated Parmesan cheese over the vegetable mixture. Then, sprinkle the breadcrumbs evenly on top for a crispy finish.

Step 5: Bake

1. Bake in the Oven: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden and bubbly.
2. Cool and Serve: Once baked, remove from the oven and let it cool for a few minutes before serving.
