Broccoli 3-Cheese Impossible Quiche is one of those super-simple and super delicious recipes. If you love quiche but are tired of the same old ham and cheese, this modernized version is for you! It’s loaded with broccoli and sharp cheese, and because it’s impossible quiche, there’s no pie crust to worry about!
It’s impossible to describe to you how good and how easy impossible quiche is, but I’ll give it a shot! This Broccoli 3-Cheese Impossible Quiche is a quick and easy quiche that doesn’t need any pie crust. The secret ingredient is Bisquick, and while the quiche is baking, the Bisquick falls to the bottom of the quiche to form a custardy-biscuit-like bottom.
The rest of the quiche, the eggy custard, broccoli, and miles of cheese stays on the top of the quiche, so you can really see the different layers.
And boy oh boy, is this quiche ever good! All the best broccoli and cheese flavors are in this quiche which is perfect for breakfast, brunch, or even dinner! You can eat it hot from the oven, cold from the fridge, or pop a slice into your lunch and enjoy it for your midday meal.

Chef Jenn’s Tips
- Bake your quiche on a baking sheet with raised sides in case it spills on the way into the oven or in case it spills a bit while cooking.
- Don’t overfill your pie dish!
- If the top of your quiche gets too brown while baking, cover the top loosely with a sheet of foil.
- You can use some broccoli stem in this recipe, just chop them smaller than the florets.

We loved this quiche for brunch this weekend! And thanks for the tip about chopping up the broccoli stems and using them too. For some reason, I had been tossing them. Love the added veggies and less waste.
I love how cheesy AND easy this is. I’ll be making this quiche on repeat!
I have always loved broccoli and cheddar but adding that mozzarella really put this over the top! So meaty and cheesy and delicious. Thank you for a fantastic recipe!
I always thought quiche was hard to make, but this was so easy! And it tasted amazing.
I love that you use the broccoli stems in this too – it made it feel much better about not wasting any part of the veggie! And the crustless quiche was perfect for me.
This was a very good way to start the day. This was made for Sunday brunch and everyone loved it. We also added some pepper jack cheese and it turned out great.
Can this be ‘assembled’, covered night before and cooked in morning?
I don’t know. I would worry about the baking mix getting too gluey or gloopy or something. I’ve never tried this. Let me know how it works out if you try it!
