Directions

  • 1.

    Preheat oven to 400° F.

  • 2.

    In a food processor, pulse nuts until coarsely chopped. Add flour, Truvía Original Sweetener and salt and pulse to combine. Add butter and pulse until the mixture resembles a coarse meal. Add egg whites and pulse just until dough comes together and forms a ball. Add a tablespoon of ice water if mixture needs more liquid to come together. Press dough with wet hands into a 9-inch tart pan with removable bottom into an even layer and up the sides. Refrigerate for 1 hour.

  • 3.

    On a sheet pan, combine onions, balsamic, oil and 13⁄4 tsp Truvía Original Sweetener (or 2 packets) and toss to coat. Roast for 20 minutes, turning onions over halfway.

  • 4.

    In a small bowl combine ricotta, egg, salt, pepper and 3⁄4 tsp Truvía Original Sweetener (or 1 packet) and stir. Evenly spread filling on bottom of the tart shell. Carefully arrange roasted onions in a rosette pattern, saving the smaller pieces for the middle. Sprinkle with thyme and bake for 20–25 minutes or until crust is golden and filling is set.

  • 5.

    Let cool 10 minutes before cutting into wedges.

Rated 5 out of 5 by from OMG LOVE IT ! Never in a million years did I think I would like - much less love - this dish! My mom would be amazed that I actually like something with onion in the title. But I made it for my partner and the young adults in the house and they all loved it. I finally gave in and took a taste and I now have a new favorite favorite food. The Truvia gives it just the right amount of 'sweet' to make the dish work. Try it - you will be amazed!
