Preparation

Step 1

1:
Olive Oil
1 medium Yellow Onion (diced)
1 tablespoon Chili Powder
Salt
Preheat oven to 400 F. In a medium sauté pan, heat a few tablespoons of olive oil over medium. Sauté the onions until translucent, about 3 minutes. Season with salt and chili powder. Remove from heat and set aside.

2:
1/2 Cup Unsalted Butter (divided; plus more as needed)
4 tablespoons All-Purpose Flour
1 cup Milk
1 cup Heavy Cream
1/2 pound Gruyere Cheese (shredded)
1/2 pound Cheddar Cheese (shredded)
1/4 cup freshly grated Parmesan Cheese
freshly cracked Black Pepper
Melt 4 tablespoons of butter with flour in a sauce pot over medium heat. Stir together to form a dry paste and cook for 2 minutes. Slowly whisk in the milk and cream. Cook over medium heat for 5 minutes or until slightly thickened. Remove the sauce from the heat, and stir in the cheeses until melted. Add the cooked onions and adjust seasoning to taste.

3:
1 head Broccoli (chopped)
1 head Cauliflower (chopped)
Toss the broccoli and cauliflower in an oval baking dish, making sure vegetables are mixed evenly. Pour the cheese sauce evenly over the vegetables.

4:
1 1/2 cups Breadcrumbs (1/2-1 inch cubes
Salt
freshly cracked Black Pepper
Red Chili Flake
In a large bowl toss together the breadcrumbs and a splash of olive oil until bread is evenly coated. Season with chili flakes, salt and pepper.

5:
Top the vegetable mix with the breadcrumbs and bake for 30 to 35 minutes or until topping is rich golden in color. Remove from oven and allow to cool for 5 to 10 minutes before serving.


Helpful Tip:
1. The roux should become a nice golden brown before adding the milk and cream.
