Ingredients
Instructions
- Preheat the oven to 375°F and place a tray on the bottom rack. Boil at least 2 cups of water. Prepare a round pan by spraying it with non-stick spray or greasing it with 1 tablespoon butter. I love to use a springform pan for crustless quiches!
- Over medium to low heat, melt the butter and saute the 1 red onion until translucent and fragrant. Season them with a pinch of salt. The slower you saute, the sweeter they will become.
- While the onions cook, add everything else, except the 1 cup button mushroom, to a blender and blend till smooth. In the preheat oven, on the lower rack (make sure you have 2 racks set), place a pan and pour int he boiling water.
- Place the mushrooms and caramelized onions in your prepared circular pan or springform, and then pour the egg mixture over them. Stir as needed to distribute the ingredients evenly. Bake on the rack above the boiling water one for 40-45 minutes, then let cool for at least another 20 before slicing. It’ll continue to set up.Baking with a pan of boiling water creates a steamy environment for the best texture! Just don't forget to take it out when you're done.

Notes
Storage: You can store this in the fridge in an airtight container for up to 6 days or freeze it for up to 3 months. It can be reheated from frozen or thawed in the fridge overnight.
What are some more cheese options?
Any cheddar cheese will work and any flavored Boursin cheese will work. You can find Boursin in any grocery store near the specialty cheeses. How do I know when it's fully cooked?
The quiche is done when the edges are set but the center still has a little bit of wobble - similar to a cheesecake. A knife stabbed into the center should come out clean, and the top should be lightly golden brown. What if I can't find Boursin cheese?
While Boursin gives this quiche its distinct flavor, you can substitute it with a mixture of cream cheese and herbs (garlic powder, dried herbs, and a pinch of salt) or use goat cheese mixed with fresh herbs.
