Have you noticed that casseroles are making a comeback? If you’ve been following me for a while, this will be no secret to you. I’ve shared tons of my favorite casserole recipes over the years.
After all, what’s not to love? They’re relatively easy to prep, and you usually end up with plenty of leftovers! I don’t always have the time to put into cooking. So it’s always nice to know that a dish is going to last for a few meals.
However. Let me warn you about this casserole. It may not last as long as a more basic ham and cheese egg bake.
Based on the ingredients, this keto breakfast bake should last a typical family of four for a full week. But the first time I made it, my family loved it so much that they devoured it in one sitting!
Thankfully, the recipe for this keto breakfast casserole is pretty simple to make. So I took their hearty appetites as a compliment and happily baked another.
In most cases, low carb breakfast casserole will yield plenty of leftovers. It’s a great option to make ahead so you have breakfast ready for the family throughout the week. I also especially love making this dish around the holidays when we have guests in the house!
The secret faux-potato ingredient
This dish will satisfy even non-keto friends and family. So what’s the secret behind this make ahead low carb breakfast casserole?
Most traditional American breakfast casseroles rely on a carb or starch filler of some kind. Otherwise, it’s just a quiche. That’s why I wanted to mimic the texture of potatoes, but without all the added carbs. Which brings me to my secret ingredient: shredded radishes.
If you’re worried about the overwhelming taste of raw radishes, let me put your fears to rest. Cooking the radishes drastically reduces their signature bite of flavor. And in this recipe, you can’t even detect the radishes with all the cheese.
They are an excellent replacement for potatoes to add density and texture to this low carb breakfast casserole.
Substituting the radishes
There are a few options for substitutes if the sound of shredded radishes doesn’t appeal to you. Or, maybe you simply want to make the casserole with ingredients you already have on hand.
A few people have noted swapping the shredded radishes for riced cauliflower. This is a nice texture substitute that also saves time if you purchased the cauliflower pre-riced.
I also recommend shredded turnips. I use them often as a low carb potato substitute.
If you don’t have those ingredients, don’t worry. You can always turn to shredded zucchini or another veggie you happen to have on hand.
This keto breakfast casserole is very versatile, so don’t be afraid to give it a try with other veggies!
How to make keto breakfast casserole
First, prep all the ingredients. Chop the raw bacon, onion, and swiss cheese, then shred the cheddar and radishes.
Note that there is no need to peel red radishes, and you will not need to pre-cook the radish shreddings. They will cook while baking in the casserole.
Finally, beat the dozen eggs in a large bowl.
After you’ve finished prepping, add the bacon and onion to a frying pan over medium-high heat. Once the bacon is fully cooked, drain the grease, then use a paper towel to pat the bacon and onion dry.
In a large bowl, combine the cooked bacon, cooked onion, shredded radishes, beaten eggs, shredded cheddar, ricotta, and chopped swiss cheese.
Grease a 9 x 13 inch casserole pan, then pour the mixture into the pan. Bake at 350°F until the eggs are set, about 45-50 minutes.
Serve warm or store for later!
Making keto breakfast casserole ahead of time
The great thing about this keto breakfast casserole is that you can make it right before you plan to serve it. Or you can bake it ahead of time so it’s ready to serve any time!
It’s a recipe that’s perfect to make ahead of time. I recommend fully cooking the casserole before chilling or freezing. That way, it just needs reheating before serving.
Storage and freezing
Want to prep this casserole for an easy breakfast throughout the week? I recommend cutting it into servings before storing. You can store in the fridge if you plan to eat it right away. Or store in the freezer for a longer shelf life.
When you’re ready to eat, reheat the servings one at a time. You can reheat each one in the microwave or at a low temperature in the oven.

Laura
Do you peel the radishes? This sounds great
Toni Jabben
Have you ever shredded the radishes in advance, as in the day before, and keeping it in the fridge to use later? I’d like to try this recipe, but will need to “sneak” the radishes in the first time I try it.
Lisa MarcAurele
Yes! You can pre-shred them and keep them in an airtight container in the refrigerator.
Mary reeves
Surprisingly good! My husband, an avid gardener responded to my request for a few radishes by presenting me with several gallons of them. I was relieved to find this recipe, made it and can't praise it enough! Tasty, filling and satisfying! Noone believes the "surprise" ingredient!
Bonnie
Do you measure the 4 cups of radishes before or after shredding? I prefer to go by weight so it's more universal but I'd love to try this with my garden full of radishes!
Lisa MarcAurele
The radishes are measured before shredding. But the amount isn't essential so a little more or less is fine.
Judy
how do you shred the radish?
Lisa MarcAurele
I put them through the grating blade on my food processor.
Louise Vail
Love it! I used 1/4 radishes and 3/4 riced cauliflower because that's what I had available. Also added fresh mushrooms to the onion and bacon saute and fresh rosemary and pepper to the whole mix. Turned out great!
Louise
I made this recipe over the holidays and it was amazing! I substituted turnip for radish and diced up a ham instead of bacon. I also didn’t have enough ricotta so I used ricotta and cottage cheese. I saved some cheddar and Swiss for the top. It was a hit! I will definitely make this again!
Kristy
Can you be more specific on the serving size what is the ounces or grams per serving? A square could be any size haha. Thanks
Lisa MarcAurele
If you use a rectangular pan and cut 3 rows on the width and 5 rows on the length, you get 15 pieces. I calculated the data based on 15 somewhat equal sized squares.
Jeanette
I didn't have any radishes so I grated some white sweet potatoes which are probably a bit higher in carbs but I only grated 4 for the whole recipe and it turned out scrumptious❣
Dorothy
When giving the calories for each recipe,is it for the whole dish or per portion. Thanks
Lisa MarcAurele
It's per serving.
Maureen ledgerwood
What can I use instead of radishes hate them thanksj
Lisa MarcAurele
You can leave them out or use cauliflower, turnip, or another veggie.
Debra A Mathre
Could I use zucchini in place of radishes and sour cream in place of ricotta?
Lisa MarcAurele
Those substitutes should be fine.
Georgieanna Harp
This is awesome and with great flavor. Radishes surely give it a “hash-brown” like texture!! We loved it!!!❤️?
STACEY CRAWFORD
Great recipe! I love that you used radishes instead of potatoes! My family will love this 🙂
Hope
This is perfect timing for me, we have a houseful of guests this weekend so will be making this for brunch! Looks so good!
jennifer
radishes! I can't wait to try it
Hezekiah
I wonder if this could be instapot cooked. I might have to look into trying that.
Lisa MarcAurele
It could definitely be adjusted to a pressure cooker. I'd cut it in half and cook it like a frittata.
Rachel Cisneros
I was wondering if I could use quark instead of ricotta or cottage?
Lisa MarcAurele
Using quark should be fine in the recipe.
Kristina
Is it 4 cups after you shred the radishes or 4 cups before?
Lisa MarcAurele
It's about 4 cups after shredding.
Kristie
What is the best way to reheat this? I tried a half recipe this morning and as promised it's very filling so we have leftovers. Next time I plan to try the bake ahead suggestion.
Lisa MarcAurele
I just put it in the microwave, but you can also reheat in a low temp oven.
John
Finally made this today and it’s wonderful! Wish I had added some mushrooms too. Next time.
Jim
Maybe I missed it; can you bake it, cut it into servings, freeze the servings and reheat one serving at a time???
Lisa MarcAurele
Yes! That works great as I typically have to much so I save the cooked pieces for quick meals later.
Ruth BLoesl
Love it, but we halve the recipe or it gets too many meals for breakfast in a row for three people. Stores great!
Lisa MarcAurele
It does make a lot so halving the recipe is a great tip!
Chez-Maree
I just made this for dinner (not breakfast), and served it with a garden salad. I didn't have the cheeses recommended, so I used wasabi, cheddar, and parmesan. I also didn't have radishes, so I used tomatoes & garlic (that I'd roasted for another purpose). Quite dissimilar to the original recipe, I know, but it just shows that it works even when you change it up. I cooked it for 40mins on 180°C (in NSW, Australia) and enjoyed it on my verandah on this warm summer evening. Thanks for the recipe.
Lisa MarcAurele
The recipe is very versatile so you can really change it up with whatever you happen to have on hand.
Ernestine Johnson
Can you use broccoli in place of the radishes?
Lisa MarcAurele
I don't see why not.
Paula Daniel
Should I peel the radishes before I shred them?
Lisa MarcAurele
There's no need to peel red radishes so I don't peel them.
Debbie
I made this for an early Christmas family breakfast. Everyone loved it. I replaced the radish with a bag of frozen "cauliflower rice" and jalapeno peppers chopped. I was asked to share the recipe with everyone. Thanks for sharing.
Lisa MarcAurele
Using the cauliflower rice in the breakfast casserole sounds like a great time saver! Thanks for sharing.
Donna
Is there a certain kind of radish you can use? My grocery store only carries the little round ones?
Lisa MarcAurele
I use either the little round ones or daikon. Any radish should work.
Jennifer B.
I will be pressed for time in the morning before heading off to the football game. Can I refrigerate this mixture (or in parts) and then bake in the AM, and if so, do I need to add time and temp to the baking?
Lisa
I usually bake it before and reheat. But you could put it in ramekins for cooking in smaller servings.
Shan
Do you have to cook the radishes prior to shredding?
Lisa
I don't cook them before adding. They cook while baking the casserole.
Terri Iverson
I couldn't find anything that makes it a "make ahead" casserole. Can it be put together the night before and baked the next morning? Or would that make it soggy?
Lisa
I usually bake it ahead and then reheat.
Gayle
Does it taste like radishes?
Lisa
My family couldn't detect them with all the cheese.
Chris
Replacement for radishes?
Lisa
You can try cauliflower rice or shredded turnips.
Barbara J Meddy
Sounds great
Mary Frances
How many radishes yield 4 cups shredded? This sounds delicious.
Lisa
I believe each cup is about 2 ounces so it's about 8 ounces but I'd need to weigh it myself. Also, the amount doesn't need to be exact.
Katherine Hackworthy
I can see why this would make a great breakfast for a hungry family. Perfect for cold Fall mornings, and would certainly keep you satisfied until lunchtime.
Lisa
It is a filling meal!
Demeter
What a great breakfast to have ready to go to feed your family! It definitely would make mornings so much easier!
Lisa
Yes it does!
Kelly Anthony
I love that this low carb casserole is quick and simple but will also feed my family breakfast all week.
Lisa
We get lots of leftovers for the week. 🙂
Heidy L. McCallum
I love a sound low carb recipe! This looks like the perfect low carb breakfast for me. I love how you have made the recipe so simple yet hearty. Can't wait to make this one morning soon. Pinning.
Lisa
Thanks for the pin!
kim
This looks so delicious! I will definitely come in handy around the holidays when hosting guests. Can't wait to try it!
Lisa
