This spring allium onion tart with leeks, green garlic, and manchego cheese is a light dinner or appetizer perfect for a spring evening.
I love reusable silicone baking mats (<-affiliate)! They’re awesome for roasting vegetables, and you can use one to line your baking sheet for this onion tart instead of parchment paper.
I recommend this all purpose gluten free flour mix (<-affiliate) for your baking needs. And it will work great for this onion tart.
While this recipe means to use all the oniony things exclusively, it would be excellent with precooked, sliced potatoes. Asparagus and spinach would be nice additions. You can use parmesan cheese instead of manchego, or even swiss or gruyere cheese. A few mushrooms and even cooked white beans (whole or as a puree) would be lovely in this onion tart to serve as a meal.
