Preparation

Step 1

Preheat oven to 450°F.

Place cauliflower florets on a cookie sheet, drizzle with olive, and season with salt & pepper.

Roast in oven for 20 to 25 minutes until browned on edges. Shake cookie sheet occasionally to turn over cauliflower (or use tongs) so evenly roasted.

Meanwhile, slice onions thin and saute onions in olive oil over low/medium heat

Season with salt & pepper. Cook onions until caramelized and brown. After about 15 minutes, add garlic and continue to cook until onions are translucent and brown

In a sauce pan, melt butter. Whisk in flour to make a roux, when all combined and cooked a little, whisk in milk until sauce has nice consistency. Add most of the cheese and continue to stir until smooth and creamy. Save some cheese for the top.

Add cauliflower to cheese sauce and stir. Add caramelized onions and mix well. Turn out into large pie dish or other casserole. Top with cheese and bake at 350°F until top is browned.
