This crust is my new favorite thing, for Pesach and all year round! Feel free to get creative with fillings — it would be perfect with a milchig quiche or frittata, too.
Preheat oven to 425 degrees Fahrenheit (220 degrees Celsius).
Peel the sweet potatoes and, using a very sharp knife, cut into one eighth of an inch (.3-cm) rounds. Spray a round baking dish or tart pan with cooking spray and lay some of the sweet potatoes on the bottom of the pan, overlapping somewhat so there are no gaps. The sweet potatoes will shrink while cooking, so make sure the slices overlap enough. Take additional slices and stand them up around the edge of the pan, overlapping by about quarter inch (.6-cm), creating a crust. Spray again and season with 1/2 teaspoon salt and a pinch of pepper.
Bake for 25 minutes or until the top edges are starting to brown. Remove from oven and let cool. Lower oven heat to 350 degrees Fahrenheit (180 degrees Celsius).
Choose sweet potatoes that are not too wide, so they can be easily sliced. You’ll most likely have some extra sweet potato slices when you’re done.
Meanwhile, heat olive oil in a large frying pan and sauté the onions and garlic until they’re lightly golden. Remove from heat and add the eggs, remaining teaspoon of salt, and 1/2 cup panko crumbs. Pour into prepared crust and sprinkle with the remaining panko. Bake for one hour or until set.
This was really good fresh out of the oven but did not perform well rewarmed.
Panko Crumbs Substitute Would either almond flour or tapioca starch work instead of the panko crumbs?
I would use almond flour or regular breadcrumbs or matza meal.
Make in advance Does this freeze well?
This recipe is on repeat! Just wanted to let you know that I’ve made onion tart with sweet potato crust last year Pesach and this year, and it’s gotten rave reviews!! I adjusted the recipe slightly (substituted potato flour in place of panko crumbs and omitted garlic as we don’t use either on Pesach) and its been eaten soon after emerging from the oven! whoever I gave the recipe to has repeated and written down for posterity. Thanks for great recipes!!
Yum. Sounds great.
Thank you for the kind words! I’m so glad you enjoy it.
