This mouthwatering tart blends woodsy mushrooms with fresh spinach in a rich, velvety egg base. It works for any occasion - from fancy brunch centerpiece to quick dinner with a side salad, making every forkful something special.
I've tried making this dozens of ways, and I can tell you that cooking those mushrooms till they're nice and golden really brings out amazing flavors you won't forget.
Premium Ingredients Key

Mom always told me to cook mushrooms in smaller amounts so they brown nicely instead of steaming. This little trick totally changes how they taste.
Perfect Pairings
Try this tart with a simple green salad and light champagne dressing. For morning meals, add some fresh fruit and crusty bread on the side.
Tasty Twists
Switch things up by adding sweet roasted red peppers, slow-cooked onions, or trying different cheeses. If you eat seafood, smoked salmon makes a fantastic addition.
Storage Smarts
Let the tart cool all the way before putting it in the fridge. Wrap it up good in foil and eat within three days. Warm single pieces in a low oven until they're heated through.
I've made this tart for years, and I've learned that taking your time really pays off. When you properly cook the veggies and get that egg mix just right, people won't stop talking about it.
More Serving Ideas
Cut leftover tart into tiny squares for fancy finger food. Serve cool at parties or take to work functions. Make a pretty brunch spread with tart slices, berries, mixed nuts, and special breads.
Heat Know-How
Getting temperatures right makes all the difference. Let your stuff sit out before mixing. Cool your tart on a rack so it doesn't get wet underneath. When warming up leftovers, go slow at 325°F for about 15 minutes to keep it nice.
Prep-Ahead Tricks
Do the parts separately to save time later. Cook your veggies up to two days early and keep in the fridge. Bake the crust a day before. Put it all together right before baking for the freshest taste.

Party Planning Strategies
Make twice as much for bigger groups using two pie pans. Try mini versions in muffin tins for cute party bites. Set up a build-your-own bar with different fillings for special brunches.
Year-Round Variations
Try tender asparagus and herbs in spring. Summer calls for juicy garden tomatoes and basil. Fall is perfect for sweet roasted squash. Winter works great with slowly browned onions and hearty root veggies.
Quick Fixes
Stop crust from pulling back by chilling it well. Avoid lumpy filling by keeping oven heat medium. Fix watery issues by making sure veggies are fully cooked first.
I first learned this dish in cooking school but really got it right through years of making it for family brunches and friend get-togethers. It's become my go-to recipe because it's so flexible and reliable. You can serve it cool at garden parties or warm for cozy dinners, and it always gets compliments while being super practical.
