How To Make caramelized onion and roasted cauliflower tart

  • 1
    Preheat oven to 450F. Toss the cauliflower in the oil. Spread out onto a non stick baking sheet. Season with salt and pepper. Cook for 15, then flip. Cook 15 minutes more and remove from oven.
  • Caramelized Onions

    In a good skillet, bring 1 1/2 tbps of good olive oil to a shimmer. Add thin sliced Vidalia onions, add in a pinch or two of salt and pepper and stir, stir, stir...for about 30 minutes until they turn a beautiful golden brown. Don't ignore those fronds.
  • My crust.  I like it but I am not a huge fan of dijon mustard

    MAKE UP THAT DOUGH: I really hate working with pastry, but this was pretty harmless.
  • This is really decadent!

    I used a whisk: Flour, cornstarch, salt and butter. Then add in the egg. I lost my pastry blender in the move to the lower 48 and had to use a fork....gave that up quick and used my grandma's fingers to get the pea sized effect I needed.

    Smash that dough all together and roll it thin. Yes, I cheated and used plastic wrap as a medium. Transfer the dough to the tart pan and press in. Now lightly coat the dough with 1 TBSP Dijon mustard, bottom and sides.

    Layering the Stuff: After pressing in the tart dough and brushing the bottom and sides with dijon, add in the onions. Top with cauliflower.
  • 7
    In a bowl, mix the eggs, marscapone, cream, white pepper, nutmeg and Guyere. Pour over the top of the tart. I had to use my hands to redistribute the cheesiness.
  • Dang, but that is the icing on the cake.....shut the door and come to the table.

    Top with 1/3 cup Parmesan cheese. Bake 350F for 40 minutes.
