ROASTED CAULIFLOWER WITH CARAMELIZED ONION GRATIN RECIPE - (4.3/5)



Roasted Cauliflower with Caramelized Onion Gratin Recipe - (4.3/5) image

Provided by DWatkins23

Number Of Ingredients 11

1 head cauliflower, broken up into florets
2 tablespoons olive oil
Salt and pepper
1 1/2 large sweet yellow onions
1 1/2 tablespoons garlic, minced
1 tablespoon olive oil
1/4 cup butter
3/4 cup flour
3/4 cup milk
1 1/2 cups cheese, grated (white cheddar and parmesan is good mix use something that's "sharp" Asiago or aged cheddar).
Pepper

Steps:

  • 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.

Tips:

  • For the best caramelized onions, use a large skillet and cook them low and slow. This will allow them to develop a deep, rich flavor without burning.
  • If you don't have a food processor, you can grate the cauliflower by hand using a box grater or a cheese grater with large holes.
  • Be sure to press the excess moisture out of the cauliflower before adding it to the tart crust. This will help to prevent the crust from becoming soggy.
  • If you don't have any thyme on hand, you can substitute another herb, such as rosemary or oregano.
  • For a vegetarian version of this tart, omit the Parmesan cheese.

Conclusion:

This caramelized onion and roasted cauliflower tart is an easy and delicious weeknight dinner that's perfect for any occasion. It's also a great way to use up leftover roasted cauliflower. The tart is flavorful, satisfying, and sure to be a hit with your family and friends. So next time you're looking for a quick and easy meal, give this recipe a try. You won't be disappointed!
