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!

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.
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
I am over the moon with this recipe YUUUUUMMMMY!!!!!
★★★★★
Do you think it would be okay to use fresh spinach, instead of frozen?
That’s what I was wondering. I have a bag in the fridge.
First let me thank you for all of the wonderful information you’ve chosen to share with us!! I plan to attempt the keto diet soon. I do hope this is not a question that will bother you but I’d just like to know if I may substitute all of the sausage/pork contained in your menus with like beef link sausage. I do not eat pork. Secondly, is there a maximum time to stay on the keto diet?
Thanks,
Tosha Meadows
You can absolutely substitute beef for pork – or even turkey sausage if you like. There are countless people who maintain a keto diet for years at a time for optimal health. Each person is different, you’ll just have to see what works best for you!
I made half your recipe, in muffin form, and I made a mistake of using just 5 eggs instead of 6. But they still tasted great! Thanks for sharing low carb recipes. What you do is very helpful. :)
Thank you Lott!
I just wanted to let any fellow low-carb vegetarians out there know that I tried this with Morningstar Farms’s Sausage Patties instead of real sausage and it was delicious! Even my Hungry Carnivore spouse loved them (I made them in a muffin tin). If your carb total allows, a thin slice of tomato, blotted, on top is delicious.
For the muffin version..did you use a silicone pan or something? My regular muffin tin was very hard to get clean afterwards! I sprayed with Pam…finally let it soak all day and with Vrillo got it clean. Thanks for any ideas!
I put the silicone muffin cups in my pans, they peel right off.
Hi, and Thank you, I was wondering how many squares you are cutting that 13×9 pan into?
12 squares, as stated in the recipe yield Christy. Enjoy!
Hi I’m new to this and love this idea. Just wondering if you have any thoughts on an alternative cheese? I can’t do feta.
Thank you!
You can use cheddar or even parmesan to give it that salty tang that you’d get by using feta. Pretty much any cheese will work though – it just changes the flavor slightly. Enjoy!
hi, this looks great! we have nut allergies, would I just add more heavy cream when I eliminate the almond milk?
nevermind I just saw you answered it above by adding some water..sorry!!
I have made this twice now and I love it. A batch in the fridge is great to be able to turn to at either breakfast, lunch or dinner.
Hi. Ok, I must have not squeezed the frozen spinach enough bc my frittata, though delicious is a little too moist. Almost spongy…kind of, watery. Any thoughts how I can fix it? I’m wondering if I put it on 200 for a little bit maybe the water will evaporate? Any thoughts would be appreciated.
think I am adding mushrooms to mine tomorrow morning!
I love mushrooms, so I’m down with it! ;)
I’m in Arizona, there are no JONES products available here. The only sausage they sell online are $75 worth of links! Perhaps you can pull some strings and encourage them to widen their horizons and have their products available in more locations.
I’m still going to try the recipe… ugh, but I know all sausage has either sugar or corn syrup. I didn’t want to add any sugars to the keto! Maybe I’ll try to make homemade sausage.
Sorry Melanie, they don’t sell it where I live either so I’m thrilled that they send me product for the recipes. There are a few other brands that don’t use sugar, sometimes the smaller local brands – keep searching and hopefully you’ll find something you can use!
AllRecipes.com has a spice combo under their “Turkey Breakfast Sausage” recipe. It makes turkey taste like pork sausage, if you use something besides ground breast (have to have a little fat in it). Good luck!

Hi! I’m trying to order the Jones sausage but I’m not having success with their website. Recipe looks great though- can’t wait to try it!
The Jones sausage is really great Stephanie, but if you can’t get it you can substitute another sausage as long as it’s got 1g carbs or less per serving!
Is it possible to make this without the almond milk and use more heavy cream (and some water) instead?
Yes Audrey – definitely. About 2 Tbsp of heavy whipping cream to 6 Tbsp of water should do it.
I would love to see more beef recipes. :)
I’m always excited about recipes that incorporate a bit of protein with veggies.
More bacon recipes please! I always have bacon to use.
I would like to see more egg dishes. Thanks
I love love love the little muffin tin idea for this, better portion control
This one is a hit with us! It browned beautifully around the edges and looked as good as it tastes. Yummy! Thanks! Keep up the good work.
mmmm I love fritata’s or quiches.
It would make a great addition to the pans I have. Love it.
I would love to win that pan!
Going to make these !
Something with sausage… and cheese… and perhaps an apple… or maybe apple sausage!
I need to move. And eat this once I settle in to my new American digs. Right out of the pan I just won. *giggles*
Maybe a recipe for low carb stuffed mushrooms?
This is a great recipe and giveaway. Can’t wait to make it and I surely hope I win. Thanks!!
And as far as recipes go, I miss my Poppy’s S.O.S. (sausage gravy over biscuits). Maybe that request is too easy, but I’d be most grateful. Thanks!
How about some low carb DIY bacon, by DIY I mean brine, smoke, slice yourself. Seems most bacon recipes I’ve found have a butt load of sugar in the brine which increases the carbs in the meat…
Sounds so good. would love to have this cast iron skillet.. to cook HAM
I would love to see some additional appetizers using Jones Dairy Farm products :)
I love bacon and sweet items together. While I don’t eat much bacon due to a missing gallbladder, I have had low carb, gluten free pastries with bacon added and it was delicious.
This looks fantastic! Would make great party bites for the holidays!
I would love to see some recipes to use for Christmas morning with my family. I love, love cooking in cast iron!!
Great recipes! This one sounds DELICIOUS and I’m going to make it this week!
I love sausage!
Love your recipes. I also love cooking in cast iron. Thanks for sharing Melissa.
Melissa I love all your recipes and your blog. I love Jones Sausage and will be making the Frittata you posted today.
congrats Melissa what an awesome opportunity. This looks awesome and so easy can’t wait to try it
Omg! This looks awesome! Can’t wait to make it! Thank you for all the amazing recipes and all your hard work!
This look yum delish. Thanks for the opportunity.
How about all three! YUM
I like your style Patti! ha ha! :)
I would love to see more lunch and dinner recipes using “traditional” breakfast meats, especially suasage.
Me too Erin, I’ll be working on that for sure!
I’d like to see some low carb pizza recipes!
Absolutely! I’ve got some great projects going featuring pizza coming up so stay tuned!
I am going to use some chicken apple sausage, I like a little sweetness in my savory, this recipe is very simple, love it!
I love to mix sweet and savory too Margarita – enjoy! :)
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 would love to see a anything with bacon!!
Yes to bacon IN ALL THE THINGS! ;)
This looks like a great opportunity! I love the idea of freezing them for later!
Thanks CC, I’m excited about it! And yes, it’s SO super convenient to freeze these for later! Hope you like them!
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!
