You can garnish the top of the quiche with additional shredded cheese, a sprinkling of smoked paprika, and/or thinly sliced tomato rounds before baking if you like.

To make a crustless quiche, simply omit the crust. It works great. You can stir the mustard into the custard mixture or omit it entirely.

Can I use veggies other than zucchini? That should work! 1) Use only non starchy veggies. 2) Use them in place of the same quantity of zucchini. 3) Sauté until tender and drain excess liquid as directed before stirring into the custard mixture.

Oat fiber: This versatile low carb flour can usually only be found online. Not all brands are created equal, but I like LifeSource oat fiber. Use gluten free oat fiber for a gluten free option. Oat fiber and oat flour are different and are not interchangeable.

I made this zucchini quiche about 5 times before getting it perfect. The pictures in this post are actually from Take 3 or 4 and the recipe as written may come out looking slightly different. I didn’t feel like rephotographing it, sorry. If you want the quiche to look like the pictures here, you can put part of the cheese on top of the quiche before baking instead of mixing it all into the custard.

Allergy info: Gluten free (use gluten free oat fiber). Nut free.
