Quiches are so forgiving, you can add ingredients you love like sausage or roasted sunchokes,and sub out things you’re not into, like mushrooms or chard. This quiche could easily have some smoked salmon, spinach, sun dried tomatoes or even bacon. I love this as a make ahead recipe; if you want to have it done the day before it’s easy to warm up. If you want to do all the prep work the day before you can throw it together in a few minutes and pop it into the oven before people arrive. This quiche also travels well so it’s great for a potluck! Let me know what ingredients you would add in the comments!
OK so I’m calling this a cheese and onion quiche but it is packed with TONS of veggies. Beautiful Swiss chard, delicious mushrooms and zucchini. This was so good that immediately regretted sharing….
This might sound crazy but my favorite part of the quiche might be the crust! The lemon zest I added made a monumental difference, you’ve got to try a lemony pate brisee if nothing else.
I want to say a bit about the baking. It’s going to depend on the size of your quiche. I made a VERY deep one and it took about an hour in the oven. I will say that as it cools the filling sets up more so don’t be afraid of a bit of wobble. You can also tent your crust for part of the baking to prevent burning but it’s kinda optional depending on the bake time you’ll need.

Feel free to modify this recipe and use whichever vegetables to you love! Just cook them down first to keep the water content low.
