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!

Delicious. Used fresh chopped spinach. Precooked the sausage. Added hot pepper flakes and Italian seasonings. Substituted 1/2 cup water for the almond milk. Baked in a 9 x 13 pan. Started checking for doneness at 30 minutes. Ended up with a total cooking time of 40 minutes (instead of 50).

Could you sub bacon for sausage in this recipe??
Yes, I don’t see why not!
This recipe is EASY and DELICIOUS. Made in the casserole, you get 12 perfect breakfast sized servings. I made it on a Sunday and the family and I ate it all week long. They liked it warm or cold. Even my sons liked it! I liked how UN-fussy this recipe was – you literally toss everything in the casserole, pop it in the oven, and forget it until it’s done.
This is a wonderful breakfast when you want eggs!

I make something similar but never thought of including sausage. I love egg, feta & spinach together. Sometimes I also substitute the feta for goat cheese.
Can you please tell me of a brand of sausage that is sugar free? I have searched high and low.
Hi Heather,
It’s REALLY difficult to find any that have zero sugars. My stores don’t carry any anywhere here. It seems most are going to have 1g or the mysterious <1g that I've found. I've had plenty of success with food items like those, as long as you look through the ingredients and see that there are no *added sugars. Another thing you can look for is the notice at the bottom of the nutrition label that says "Not a significant source of calories from x,y,z" – if sugar is mentioned there, you're good.
This is a delicious easy recipe that even tastes great quickly reheated throughout the week. The feta is a very subtle flavor with the sausage and spinach playing a starring role. My family said they’d eat this even if not eating Keto.

You don’t cook the sausage first??
I just made this last night and have added to my menu rotation. It is great for a quick meal on days your running late. Love the flavor. My husband even likes it!

Great recipe, the family likes it hot and cold.

Can anyone help please? Cups are not a very scientific measurement and so I have no idea how much cheese to add. Thanks in advance…
I would guess 2 ounces. A lot of cheeses are roughly 1/4 C per ounce.
I have an almond allergy in the house. All other nuts are fine though. can soy milk or cashew milk be substituted in the recipes that call for almond milk?
yes!
I made this today and it was awesome. I will be making this again.
This is an AMAZING dish!! I didn’t have nutmeg so I substituted allspice and it was awesome! Great recipe. I’ll definitely be making this again!

Just wanted to let you know how happy I was to find someone like you willing to help people get healthy without asking for any payment. Today is Friday and Monday I will be starting keto along with intermittent fasting I will keep you posted because your recipes are very helpful along with the shopping list I am so grateful to you because believe it or not this is so hard for me to do and you have done it for me loving it ………..will definitely keep you posted on my success thank you so much Gigi
Several people asked, but I didn’t see a response, so I figured I would! I didn’t read the recipe thoroughly when making my shopping list and wrote down that I needed 10 oz of spinach (forgot to write down “frozen”). I actually didn’t realize I bought the wrong kind until the directions said to squeeze the remaining liquid from the spinach. Long story to say that fresh spinach, chopped up, works great in the casserole form of this recipe! It is delicious. Thank you for the recipe!

I had this exact question so thank you for posting!!
So I have a question. In terms of mayonnaise, breakfast sausage, and bacon, do we need to be looking for items with no added sugar or sweeteners? Almost all breakfast sausage and bacon have sugar, normally maple syrup or brown sugar. I have done Whole30 and wanting to try a less restrictive diet and something I can maintain. I resorted to having to buy plain ground pork and add sausage herbs and seasonings to make my own because I had such a hard time finding breakfast sausage with no sugar(s). Any feedback is appreciated!!
I was having the same problem with breakfast sausage, but I found ONE brand at my local grocery store that had no sugar in only one of its sausage products. It’s the Jones Dairy Farm Sausage Roll. Hope this helps!

Loved this. Just made casserole dish cut into squares and am delighted. Just wondering how do I go about freezing. Should I put in individual freezer bags or lunch boxes and how do I reheat after-or can I just defrost and eat cold or should I defrost overnight & oven bake etc?
Baggies work and I microwave it for 30 seconds before eating!
This is a great menu plan, however was wonderingwhat is the easies way to go about substituting something in the meal for something else. For instance I don’t care for the sausage and spinach frittata,
Just found your website, starting today. Made the frittata with broccoli and sharp cheddar- terrific, thanks

Can fresh spinach be used in this recipe? I don’t see a response to this question raised earlier
Of course fresh spinach can be used it’s the same thing as Frozen
