Beef Fajita Crustless Quiche


As of midnight tonight, we here in Austin (and surrounding areas) are on official lock down with a ‘shelter in place’ until April 13th. This comes after being under a quarantine mandate for a week or so as well. Being as times are tough for everyone, I’m trying to be super creative in how I use up leftovers and the few pantry staples that I have been able to get my hands on.

Being as we had beef fajitas a few nights ago, I had some leftover cooked beef and peppers and onions. So I thought I’d use them up in a quiche because when growing up, quiche was one of the few ways that my family would repurpose leftovers. It’s simple, easy, and delicious every time.


This crustless quiche is low in calories and carbs while being gluten-free and keto-friendly! I served mine with a spiced up tomato soup and topped the quiche off with green onions and just a touch of salsa. All in all it was a yummy and guilt free dinner that allowed me to stretch one meal into two!

This quiche would also be good to pair with some sort of Tex-Mex style salad on the side.

Got chicken or veggies fajita leftovers instead? Feel free to use that instead. I only used beef just because that’s what we had on hand at the time. But any sort of fajita leftovers will work just the same and be delicious.


One of my favorite things about quiche too, is that it’s perfect with being used for any meal time; breakfast, brunch, lunch, or even dinner! This time around for us, it was dinner.
