This Keto Sausage, Spinach & Feta Frittata is super easy to throw together and reheats well all week long. It’s even delicious cold, making it perfect for back to school or for a quick low carb meal on the go between work and the gym!

This super easy Keto Sausage, Spinach & Feta Frittata is comforting to eat and simple to make. You’re basically throwing everything together and baking it until set. The subtle, herby flavor of the sausage pairs nicely with the salty feta and earthy spinach. You can bake this as a keto casserole to cut into slices for a crowd, or in muffin tins for a more portable breakfast or snack.

I made both styles this time, and threw the muffins in the freezer where they will keep for up to a month. Now I can just pop them out and nuke them for 30 seconds when I’m in a hurry and need something I can eat quickly.
Mr. Hungry and I both love this Keto Sausage, Spinach & Feta Frittata recipe and I hope that you will too!

arlene lawson says
great idea – was just thinking how to change this for my daughter who doesn’t eat pork.
as for me, I’ll probably go the bacon route, as I don’t usually like the flavor of the herby stuff, altho I use many of the Jones products.

Hi, I know this is an old post, but I wanted to answer this question for anyone who might see it and wonder the same thing. We don’t eat pork in our family either, so I make my own ground chicken sausage and it is delicious! I got the recipe from Kitchen Stewardship, http://www.kitchenstewardship.com/2012/10/03/how-to-make-homemade-sausage-seasoning/.
Brown 1lb of ground chicken and season with 1tsp fennel, 1 tsp Real Salt, 1/2 tsp black pepper, and 1/4 tsp cayenne. I always taste my meat after it’s fully cooked (and “spiced!”) and adjust, if necessary, according to my preference.

I don’t really know how to write a new so replying to your post. I just made these Sausage, Spinach & Feta Frittita and they are wonderful. OMG I love them so much. And it’s nice they freeze well to eat later since I’m the only person eating them. Thank you!
