Spring is here and we can finally enjoy delicious—and healthy—fresh vegetable delicacies, like this Italian-inspired Spring Onion and Asparagus Crostata. What makes it really stand out is its crust—made from a rich cream cheese dough traditionally used in rugelach, the famous Jewish curled-up cookie. You’ll love this savory twist… with spring herbs and caramelized onions.
Spring Onion and Asparagus Crostata
Makes 2 tarts (crostatas), serves 12 as a main course or 20 as an appetizer
1. Begin by caramelizing the onions. Slice your 2 yellow onions thinly. In a pan over medium heat, cook the sliced onions until they become translucent. Then, put the onions on low and cook for 30-40 minutes stirring occasionally. While the onions cook, prepare your crust.
2. In a mixer, blend cream cheese and butter. Add in the sugar, 1/2 tsp. of salt and 2 Tbsp. of Parmesan. While this is blending, use scissors to snip the chives until you have 1/2 cup of minced chives. Add the all purpose flour and whole wheat flour to the mixer and stir on low so the flour stays in the mixing bowl. When the dough begins to come together, add in the chives. Once the dough forms a ball, take it out of the mixer and wrap it in plastic wrap to make 1 large disc of dough. Refrigerate for at least 30 minutes. You can also make the dough a day in advance if you prefer.
3. Preheat your oven to 350°F. Remove your caramelized onions from the pan and let them cool. With a mandolin, a sharp knife or the slicer on your box grater, thinly slice 2 spring onions. Set the onion aside.
4. In a separate bowl, mix the ricotta, 1/2 cup of grated Parmesan, 1/2 tsp. of salt and pepper. Take the dough out of the fridge. If you have chilled the dough overnight, it may need about 30 minutes on the counter before it is workable.
5. Trim the asparagus by snapping off the thick bottoms. They should snap naturally at the beginning of the tender part of the stalk. Cut the asparagus in half horizontally and then in half again vertically.
6. Cut the dough in half. Roll out one half of the dough into a circle. It does not have to be a perfect circle since a crostata is a rustic dish. The dough should be between 1/8 to 1/4 inch thick. Spread 1/2 of the caramelized onions around the edge of the dough. Curl the dough over and tuck it into the base of the crostata crust. With scissors, snip little vents along the curled crust. Repeat with the second half of the dough and caramelized onions.
7. Top the crust with 1/2 of the ricotta filling. Layer 1/2 of the spring onion slices on top of the ricotta filling. Carefully arrange the asparagus over the onions. Repeat with the second crust and the other 1/2 of the ricotta filling, spring onion slices and asparagus.
8. Bake on a cookie sheet lined with parchment paper for 45-55 minutes. The crust will become golden brown along the edges.
9. Serve with a spring salad. If you have leftover asparagus, you can shave the raw asparagus with a vegetable peeler and top with a homemade salad dressing or whatever dressing you have in your fridge. Look for pea shoots at the grocery store or farmer’s market; they make great spring salads as well.
