How many net carbs are in this keto breakfast casserole?
There are only 1.6g net carbs in this low-carb breakfast casserole. Breakfast casseroles tend to be low in carbohydrates as they are primarily made of eggs, cheese, meat, and low-carb vegetables.
Keep in mind, that if you add certain items to this dish, such as extra tomatoes, your carb count may be slightly higher than you want if you are following a low-carb diet or a keto diet.
If you don’t mind a few extra carbs and would prefer to have a pie crust, you can make a keto almond flour pie crust or a keto coconut flour pie crust.
Ingredients you need
Part of the fun of this keto breakfast casserole is that you can swap out ingredients to make it perfect for you. You can make so many variations the whole family will love.
That being said, I know it’s helpful to have a recipe, so this is what I put in my breakfast casserole. All quantities, instructions, and prep time are in the recipe card below.:
- eggs – fresh medium eggs or large eggs.
- heavy cream or milk – make sure to choose full fat as it will give this breakfast casserole that extra creamy texture without too many added sugars.
- green onion – sliced green onion (spring onion) adds colour and flavour.
- bacon – in this basic recipe, I use diced bacon. However, I’ve also made this with cooked sausage or ham and it’s fantastic.
- shredded cheese – I usually use shredded cheddar cheese since I almost always have it, but use whatever grated or shredded cheese you have on hand. Shredded mozzarella cheese is also fantastic.
- cherry tomatoes – I love the juicy pop these tomatoes add, but you can swap this out for other veggies like broccoli or spinach.
- salt and pepper – add to your liking.

💭 Variations

You can even add your favourite herbs such as basil, chili, rosemary, or maybe a pinch of curry powder. The fun part of keto breakfast recipes like this is that the egg mixture and bacon go so well with a large variety of flavours.
That being said, I also like this dish with breakfast sausage. It’s truly one of my favourite gluten-free low-carb family-friendly recipes!
You can truly change the entire compensation and taste of this dish just by swapping out the seasoning and veg!

🥗 Serving
When serving a breakfast casserole, it can be served hot or cold. If you’re in a hurry you can even eat a cold slice in your morning rush while on the move.
Serve with sour cream, keto BBQ sauce, hot sauce, mustard, cooked breakfast sausage, or mushroom sauce. It really is the easiest healthy low-carb breakfast for a family.
I like to enjoy this warm out of the oven for a weekend brunch. I typically pair it with a side salad that is tossed in a nice vinaigrette or my magic 1-minute mayonnaise. The flavours play very well together with the creamy eggs.
I also have eaten this crustless egg and bacon pie cold at work or sent it with my kids as a healthy packed school lunch. I have even taken this dish with me on a picnic—it’s quite lovely.
I love making breakfast casserole (or some may say crustless quiche or frittata) because you can simply throw anything in from your vegetable drawer, or leftover cooked meat, and voila. You have a high-protein breakfast or lunch.
🌡️ Storage
How long can will bacon and egg pie last in the fridge?
If you keep it well covered, or in an airtight container, your pie should last about 2-3 days in the fridge. Since this is a crustless recipe, you don’t have to worry about a soggy pastry base.
How to serve leftovers
This keto breakfast casserole makes the perfect leftover! It can be served for any meal. A crustless quiche is sturdy enough to survive the school lunch box and adaptable enough to suit even the pickiest child.
Can you freeze extras?
Yes. Either as a whole or as individual slices with baking parchment in between each slice. Always store in an airtight container to avoid “freezer burn” and to prevent it from absorbing other food odours.
FAQs About Keto Breakfast Casserole
Much like a typical baked quiche, you can tell when it’s done cooking by inserting a toothpick, or a knife into the center of the casserole. If it comes out clean, it’s done baking. If it’s still wet, keep it in the oven!
Honestly, this recipe is so simple that it takes only 5 minutes to prep. So really it’s not worth prepping ahead of time.
Yes, you may omit the milk and cherry tomatoes.
It is a high-protein low-carb breakfast casserole already, but to add more protein, add your favourite breakfast meat such as spicy sausage, Italian sausage, ground sausage, or and leftover meat.
The milk is in the recipe to make a lighter and fluffy breakfast casserole (quiche). However, it may omited but you will get a smaller breakfast casserole.
If your bacon pieces are small, you can add them raw and they will cook at the same time as the raw eggs. If your bacon pieces are large, I would suggest cooking them first just to make sure the bacon is safe and cooked.
Yes, allow the breakfast quiche to cool completely in the baking dish then slice and store in an airtight container. Store in the freezer for up to 2 months. Defrost by removing your slices and leaving them covered on your kitchen benchtop for 1-2 hours. Reheat by placing in a warm oven, in a skillet over medium-high heat, or microwave.
Yes. Place the sausage meat in the bottom of oiled (with cooking spray) muffin tins and pour the egg mixture over the sausage for an easy breakfast casserole with sausage.

AND More Stinkin B.A.C.O.N. lol
Thank you for this recipe. Now I know what to have for lunch.
I will also add mushrooms to this recipe.
+++ more bacon!
Excellent recipe and so versatile – thank you!
This is so delicious, made it last night – yummy! 🙂
The bacon goes into this uncooked?
Yes. I skip every step possible when making dinners. With 3 children, I’m not going to do anything unless absolutely necessary. I also try and make my recipes as easy as possible then there is more chance for people new to LCHF giving it a go. I find too many people overcomplicate things. “Real Food, Real Easy” is my motto 🙂
american bacon is mostly fat and english bacon is more meaty. So, for US, i would cook bacon first or use bacon bits!!
How long do you bake it for?
The top of each recipe panel shows cooking times. For this it is 30 minutes
Mine took at least 30 min……used ham….was great!
Made this last night and it was delicious! I didn’t add any extra veggie as to keep the carbs down. Yum!
Do you Think it would freeze?
Yes it does. I always wrap it in baking paper then in an airtight container in the freezer.
Hey can I just substitute the full fat milk for low fat as full makes me sick or do I need to add something else
Sure. I would decrease the milk from 150ml to say 100ml as the low fat milk will be a bit more watery and so may make the egg mixture a bit too sloppy when baked.
Libby, thank you so much for including the American metric equivalents. I have NO idea how to convert ANYthing. Very considerate of you!
Courtney

Thank you Courtney, this really means a lot.
Do you think this would work without milk?
Yes, it would just be more ‘solid’. The milk lightens up the texture a little.
can you use cottage cheese instead of cheese?
Cottage cheese may have a bit more liquid, so as long as you drain that off, it should be a nice change to use it here. Great suggestion.
I have a mess of chickens and too many eggs sometimes in the winter, so- needed a crustless quiche recipe. This is superb, easy and filled with good ingredients. Thank you much for sharing and I will continue to make this time and again.
Terry you are so lucky to haven chickens and an endless supply of eggs. I cant believe how many we get through as a family in a week (guessing about 30-40 between 5 of us). If you want to muse up even more eggs, these recipes can be frozen – salmon and cream cheese bites, ham and egg cups, spinach and feta pie. Enjoy 🙂
Thanks again!
I added a couple small home grown sliced zucchini and garnish on top with asparagus. Yum.
I might be a bit late but is the sugar in the nutritional panel from the tomatoes? I am trying to go sugar free and still a little confused!
Yes that is the sugar in the tomatoes. You could omit them if you like.
Such a good honest recipe. I use it often but with changes as I have ingredients. Today it was onion, green pepper, leftover asparagus and leftover shredded mozzarella. Last week I had a quarter cup of ricotta that I added to the scramble. I’ve also used breakfast sausage, feta crumbles, and sliced Apple. Always so good. Thank you!
Do you think this would work if it was baked in a muffin pan? Then you’d have neat little yummy muffins!
Absolutely!!! Go for it. They would be amazing low carb snacks, lunch or dinner. They could even be frozen too.
Im vegetarian so thinking i might dice up some halloumi cheese
This very nice but how do you stop the bottom from being soggy?
Make sure you choose bacon which isn’t pumped up with water. The bacon and egg pie cooks throughout to be a solid and sturdy dish. If you are still concerned, you could omit the milk to make it even thicker. I only add milk so it is light and fluffy.
When preparing the dish, do I oil the dish first and then the paper or paper first and then oil?
Oil the dish, then line with baking parchment. It allows the baking parchment to stay put.
I have just tried this & used ham instead of bacon – it is absolutely fabulous. Will definitely be making it again.
I like sausage, browned and crumbled in mine. I mix hot and mild sausage for a little kick. Could add jalapenos too. Or some Rotel.
Just wondering if it would still hold if I omit the cheese for a dairy free version
It might just have a looser texture but it would still work.
Can it be frozen?? love you have the recipes in grams for those of us from the uk and have no idea what an american cup equates to- first site I’ve found that has the conversion AND can alter the portion size so thank you! great and easy recipes for my aunt with type 2 who keeps blood sugar under control purely through low carb 🙂
I am so glad you are finding that useful, I cannot tell you how many hours it took me (and cups of coffee). Well done to your aunt for keeping her diabetes under control through low carb. Fabulous.
This looks so tasty – I just made one and put it in the oven – how do i know if its done if there is a 10 minute variation in the cooking time as it says in the last paragraph. The cooking time at the top is 30 mins.
Thanks!
I have to give a variable cooking time as everyones oven will differ, and mine does too, even on a daily basis depending on what other items I have in the oven at the same time. Simply push a fork into the centre, if it comes out clean with no uncooked raw egg, it will be cooked. Don’t over cook it, no one wants rubbery eggs 😉
You can mix all your dry ingredients and put them in your baking dish or muffin tins to make sure that you get a uniform result. Then pour the liquid over the top.
As for ingredients, I like mine pizza flavored, so it’s tomatoes, pepperoni, and anything else I’d put on a pizza.
Can I sub the cream? All out… Maybe cream cheese or sour cream (too runny?)
Sure thing. You may omit it or substitute for cream cheese or sour cream.
Why does my egg ‘split’ or look curdled ???
Hmm, not sure. What else did you add I there? Is your bacon got some extras that may have made it curdle?
Thank you Libby for this recipe. We are always looking for low carb snacks for our T1 child and this is just perfect.
Hi Libby – I love this recipe but wondered whether you had ever tried to microwave?
I tend to leave the microwave just for preparing my Fat Head pizza dough or mug cakes.
Hi Libby,
I am looking forward to making this for breakfast tomorrow and thinking that adding a few chillies would be really good.
Absolutely, go for it. Chilli is good in almost everything to pimp up the flavours.
I have made this for a couple years. Only I called it “oven omelet”. I will also add some sour cream to my beaten eggs and that adds a little zip. I will cut them into squares and take them in my lunch along with a low carb biscuit. Thanks for always giving us some good recipes.
I second this even though I’m in the states. I use grams for anything not liquid and cups for milk, cream etc. But only because I still haven’t figured out how to measure ml on my scale. I’m sure it’s easy but I think that’s what happened w the ice cream I tried to make. Too little cream. Any hints?? I also love all details you put above the actual recipe. And I don’t mind the advertisements like some others do. It’s far less than other sites have.
Thank you Marsha. I do try to cover everyone and their preferences. I love cooking by weight, it’s so much easier and so little washing up to be done as I zero the scales between each addition. And thank you for your vote for the ads, I do set them to the minimum level to cover ever-escalating costs with running my site. Not many people know I refuse sponsored content so I can remain independent and trusted. Not a very good financial choice but a moral and ethical one, hence the ads are necessary.
Use a measuring cup with markers up the side showing 1/4, 1/2, 3/4 and full cup. Also has mls going up by 50s up to 250ml. Or a measuring jug. You can buy 2 sizes, one up to 500ml and the larger one up to a litre .
Thank you for another awesome recipe Libby. Another that deserves more than 5 stars. So easy and I love that you can add whatever veggies you like. I added leftover spinach and was going to use it as my crust but didn’t have quite enough so I just added it into the mix. I like the looks of the result. Although mines not as cheesy looking on top. Guess I need more cheese next time, LOL. Seriously, everyone who likes eggs should try this. I’ll be making it almost weekly. Funny as I was having dinner I realized I need to make the cheeseburger casserole again (it uses the same pan).
Hi thanks for posting this recipe. I’ve made it a couple of time now and it works well as a quick breakfast, lunch with salad or evening meal with naughty fries. These are easy meals when looking after the G.kid.
Was acc so awesome loved it thanks
I just had to tell you that this is my favourite recipe for my work lunch. I make a big batch and freeze half for the second part of the week. My daughter is gluten-free so she often enjoys it at school too.
This is brilliant Cheryl. I love how easy making a crustless quiche is and how well they store in the freezer for quick and easy meal prep.
