Amy Chaplin's Gluten-Free Savory Tart Recipe

A main course for spring, or almost spring, that's gluten-free, vegan, and topped with fresh green vegetables. You'll love the buckwheat-oat crust.


Sweet or savory, tarts are one of my favorite things to make. I love to experiment with unusual flours in the crust and new combinations of vegetables in the filling. Tarts like this one are the perfect vessel for highlighting seasonal produce and they’re perfect dish to make ahead as they usually taste better served at room temperature. Since this is a made without dairy or eggs I needed to create a nice creamy and flavorful filling that would set up once baked and compliment the vegetables. I decided on a combination of caramelized onions and white beans with some added some flax to help it set. The turmeric gives a golden hew and the nutritional yeast lends an umami flavor that you would get from adding grated cheese. If you don’t have nutritional yeast add a little more tamari and taste for seasoning -- the raw flavor of the flax is removed by baking. Enjoy with a soup or simple salad for a great lunch or light dinner.

Green vegetable tart with buckwheat oat crust

Makes one 10-inch tart



Tart crust:

½ cup toasted sunflower seeds
½ cup rolled oats, gluten free if necessary
¼ cup brown rice flour
½ cup oat flour, gluten free if necessary
½ cup buckwheat flour
1 tablespoon arrowroot powder
½ teaspoon aluminum free baking powder
¾ teaspoon sea salt
4 tablespoons extra virgin olive oil, plus more to oil pan
4 to 5 tablespoons plain almond or soymilk




3 tablespoons extra virgin olive oil, divided
1 yellow onion, chopped
¾ teaspoon sea salt
4 teaspoons white balsamic vinegar
¾ cup plain almond or soymilk
1 14oz can white beans (butter beans, cannellini or navy beans), drained and rinsed well
1 tablespoon nutritional yeast
1 tablespoon ground golden flax seeds
1/8th teaspoon turmeric
½ teaspoon tamari
Pinch black pepper




1 tablespoon extra virgin olive oil
1 leek, cut into ½-inch slices
3 cups broccolini florets
3 cups baby spinach
½ cup frozen peas
Black pepper

Make the crust:

Preheat oven to 350 degrees Fahrenheit. Oil a 10-inch tart pan and set aside. Add sunflower seeds and oats to a food processor and blend until fine. Add, rice flour, oat flour, buckwheat flour, arrowroot, baking powder, and sea salt and blend again. Drizzle in oil while the motor is running. Scrape sides and blend again. Drizzle in soymilk and blend until mixture comes together when squeezed. Press into prepared pan, you will probably have a little left over.
Prink bottom of crust with a fork and bake for 15 minutes. Remove from oven and set aside. Leave the oven on.

Make the filling:

Warm a skillet over medium heat, add 1 tablespoon olive oil and onion and sauté for 15 to 20 minutes or until soft and caramelized. Add sea salt and white balsamic vinegar, stir and remove from heat. Transfer onion mixture to an upright blender (don’t wash the pan) and add remaining olive oil, almond milk, beans, nutritional yeast, flax, turmeric, tamari and pepper. Blend until completely smooth, scraping sides as necessary. Transfer to a bowl and set aside.

Make the vegetables:

In the same skillet warm olive oil over medium heat, add leek and sauté for 3 to 4 minutes. Stir in broccolini along with 2 tablespoons water, cover and cook for two minutes or until bright green and tender. Spread spinach over the top of the broccoli and then add peas, cover again for another minute and then stir to combine. Remove from heat as soon as the spinach is wilted. Roughly chop half of the vegetable mixture and stir it into filling. Transfer to prebaked crust, spread out evenly and bake for 25 minutes. Top with remaining vegetables and bake another 20 minutes. Remove from oven and allow to cool completely before removing from pan and serving.
