Mushroom, Chard, and Cheddar Tart

Filled with meaty golden sautéed mushrooms and vitamin-rich chard, this mushroom, chard, and cheddar tart is mostly all veggies, with a couple of eggs and a smattering of cheese to hold everything together. It’s baked in a flaky whole wheat oatmeal crust and finished with a sprinkle of crunchy roasted sunflower seeds.

At play here is what I call the amazing shrinking greens phenomenon. This time a big leafy bunch of chard greens reduces into a green tangle. When chard is your green leafy, be sure to use the stems, just pan-fry those colorful tasty stems along with the onions. When they’re soft, add the chopped chard leaves and cook until they’ve wilted and shrunk–into just enough to fill a 9-inch tart.

Mushrooms, sautéed to a dark golden color, add umami-rich flavor to the whole mix. They too shrink when cooked—so much that you can hardly tell they’re there. Except for a certain deeper flavor—mushroom umami, which highlights the sweetness and lessens the bitterness in chard.

Bake your mushroom, chard, and cheddar tart in a 9-inch tart pan with a fluted ring and removable bottom. If you don’t have one, use a small pie pan. The slices might not come out as easy, but promise, this tart/pie satisfies no matter how you present it.

I’m going to argue for the shorter-sided tart pan. Fluted tart pans with removable bottoms are inexpensive and really show off your food. Tarts, especially this mushroom, chard, and cheddar tart, are generally sturdy enough to pick up with your fingers—for enticing appetizers, cut into smaller wedges. For a light dinner, serve larger wedges along with a simple baby lettuce salad.

You’ll find quite a few mouthwatering tarts on this bloggity blog, both dessert sweet and veggie savory tarts. Like this decadent chocolate walnut tart, or this easy persimmon with its gluten-free pecan crust. For another savory tart, try this herbed goat cheese and caramelized onion tart.

I lined the pan with my dependable butter crust with whole wheat and oats. Feel free to use your favorite pie dough—or even one of those store-boughts. Shhhh—did I write that? Yeah. Well, make this tart in any pan, with any crust—this ones a keeper.
