Keto Egg Cups

Three ingredients, 15 minutes, and breakfast is handled for the week. I meal prep these low-carb egg cups every Sunday and my kids grab them straight from the fridge before school.
I don’t remember if I first tried one of these at Starbucks or Costco, but I do remember thinking: I can do this better at home with three ingredients. And I was right.
These keto egg cups are the breakfast I come back to when I want something high in protein and ready in 15 minutes. I make 16 at a time, stack them in a glass container, and my family grabs them all week. My 8-year-old checks the fridge before school to see if there are any left. That tells you everything.
The concept is dead simple. Half a slice of deli ham goes into a greased muffin tin, shredded cheddar on top, then crack in an egg. Season with salt and pepper and bake at 400 degrees. No mixing bowls, no whisking, no cleanup beyond the muffin tin.
Here’s what I’ve figured out after making hundreds of these: the bake time depends entirely on how full you fill the cups. Large eggs with a generous cheese layer need 12-13 minutes. If you’re lighter on cheese or using medium eggs, 10-11 works. I pull mine when the whites are set but the yolk still has a tiny bit of give, not runny but not rubbery either. Overbaked yolks turn chalky and the texture goes wrong. If you’re using an air fryer instead, I’ve tested that too: 350 degrees for 10-12 minutes in a silicone mold.
If you want a crispier, almost lacy edge on the meat, swap the deli ham for prosciutto. Prosciutto is paper thin, so it crisps like bacon at the edges. Ham holds more moisture, which is why it doesn’t do that. I use two slices of prosciutto per cup instead of one half-slice of ham, and skip the salt entirely (prosciutto brings plenty on its own). Reader CJ tried this with gruyere instead of cheddar and got rave reviews from her chef niece.
For variety, I rotate through different builds depending on what’s in the fridge. Crumbled bacon (cooked first), salami with feta, or a handful of spinach all work. For more batch-friendly breakfast ideas, try my sheet pan eggs, mini frittatas, or a full keto ham frittata when you’re feeding a crowd.
These store well and freeze beautifully (I cover the details below). Pair them with keto hash browns for a full plate, or just grab two on the way out the door.
How to make egg cups
Three ingredients and one muffin tin. That’s the whole setup. But here’s where it gets fun: I use this recipe as a starting point and change up the fillings constantly.
Make these your own
Variations I’ve tested:
- Bacon: crumble it on top of the cheese. Make sure it’s cooked first.
- Prosciutto: two thin slices per cup. The edges crisp up almost lacy. Skip the salt.
- Salami with feta: this combo surprised me with how well it works.
- Ground sausage: brown it first, then press into each cup.
- Spinach: squeeze out the moisture first or you’ll end up with soggy bottoms.
- Different cheeses: pepper jack for heat, gruyere for nuttiness, gouda for a smoky note.
If you want a bigger batch breakfast, my keto sausage breakfast casserole uses the same hands-off approach for feeding a crowd.

Can I make these in an air fryer?
I've done this and it works. Get a silicone muffin mold or a small metal pan that fits inside your air fryer basket, set it to 350 degrees, and cook for 10-12 minutes. I prefer silicone molds because nothing sticks. Check at 10 minutes since every air fryer runs a little differently. If you already use your air fryer for hard boiled eggs, the process feels the same.
Why did mine stick to the pan?
Not enough cooking spray. I use avocado oil spray and coat every cup generously, including up the sides. If sticking is a recurring problem, switch to a silicone muffin pan. I've never had anything stick to silicone, and you can skip the spray entirely.
Can I use scrambled eggs instead of whole eggs?
I've made both versions. Whisking the eggs first gives you a more uniform texture and makes them easier to eat on the go since there's no runny yolk situation. I still prefer cracking in a whole egg because I like the yolk intact, but the scrambled version is great for kids or for packing in a bag. Reader Joy does it this way and says they travel better.
How long do these keep in the fridge and freezer?
Mine last 5 days in the fridge stored in a glass container with a lid. For freezing, wrap each one individually in plastic wrap, put them in a freezer bag, and they keep for up to 3 months. I reheat from the fridge in 45 seconds and from frozen in about 90 seconds. The texture holds up well either way.
Should I skip the salt when using prosciutto instead of ham?
Yes. I learned this after oversalting my first prosciutto batch. Prosciutto is already very salty on its own, so adding more makes the whole thing too much. With regular deli ham, season normally. But with prosciutto, I skip salt entirely and just add a crack of pepper.
Can I use a silicone muffin pan instead of metal?
I actually prefer silicone for this recipe. Nothing sticks, you don't need cooking spray, and they pop right out. The one thing to know is that silicone is floppy, so set it on a baking sheet before you start filling it. Otherwise you're trying to carry a wobbly tray of raw eggs to the oven, and that never ends well.
What cheese works best besides cheddar?
I rotate cheeses constantly. Pepper jack adds a little heat, gruyere gets nuttier when it melts, and gouda has a slightly smoky flavor that pairs well with ham. My reader CJ tried gruyere with prosciutto and her chef niece loved the combo. I'd avoid using feta as the only cheese since it crumbles too much, but feta on top of mozzarella is a good pairing.
How many net carbs are in each one?
Each cup lands around 1 to 1.5 net carbs with almost 12 grams of protein, depending on your ham and how much cheese you use. I stick to a deli ham with zero added sugar, which keeps mine closer to 1. Pile on extra cheese and you'll nudge it a little higher, but it stays low either way. That macro split is the main reason I lean on these for weekday breakfasts.
Honey ham versus black forest, that's what took me three batches to figure out. Honey ham sweetens the cup in a way that fights the egg. Black forest is salt-forward and gets out of the way. Been on black forest ever since. Sunday routine now: tins in at 400, 10-minute pull, four cups at breakfast and I'm covered on protein until noon. The yolk window is maybe 90 seconds. Pull at 10 and you're in range, push to 12 and the batch goes firm. That's the one knock.
I pulled at 11 minutes and the yolks were already set solid, which wasn't what I was going for. First attempt at anything like this and I'll push to 9 minutes next time. The ham curls up and crisps along the edges in a way I didn't expect. Surprised three ingredients could pull that off.
Switched the cheddar for goat cheese two weeks ago and the tang against the salty ham works better than the original, at least for me. It goes almost creamy in the oven rather than melting flat, so you get these richer little pockets under the egg. Ten minutes at 400, pull when the yolks have just a hint of give. Holds up fine cold the next morning. Tried feta the week after out of curiosity. Worked, but a bit intense for 7am. Going back to goat cheese as my default and keeping feta on the list for lunches.
That tang against the salty ham is what I'm missing with plain cheddar. Goat cheese is next batch.
Been on a huge air fryer kick and I'm wondering if these translate. I have a silicone muffin mold that fits in my basket so I could probably do a batch of 6-7 at a time, but I have no idea how to adjust the temp and time from 400°F for 10-12 minutes. Last thing I want is a rubbery white but still-runny yolk situation when I'm trying to get my kid out the door on a Monday morning.
Drop it to 350, not 400. I've done these in the air fryer with a silicone mold and 10-12 minutes at that temp works. Start checking at 10. By 12 the whites are set and the yolk is just firm, no runny middle.
350 for 11 minutes and the whites were fully set. Monday saved.
Pull the ham tight up the sides of each cup before you crack the egg in. My first batch I skipped that step. Whites leaked underneath and stuck to the tin. Second batch came out clean and held together in the fridge all week.
Brian, I know better than to skip that step now. I press the ham flat against the sides and fold the top edge just over the rim. That fold is the seal. First time I rushed it, same mess. Now I do the full tuck before I crack a single egg, and they hold through the whole week in the fridge.
Crack the eggs directly over the ham cup, not into a bowl first (I tried to be careful and lost two yolks to the counter before I gave up on that plan). First time making these and 11 minutes hit the sweet spot in my oven, whites fully set with no rubbery texture anywhere. 1.1 net carbs and almost 12g of protein per cup felt borderline criminal. Do you go the full 12 minutes to firm up the yolks, or is there a way to pull them just shy of that and keep a little softness in there?
Pull at 9-10 minutes if you want softness. The whites will look a tiny bit underdone when you open the oven but they finish in the pan. Once the whites fully lose that shine, the yolk is already going firm.
Six batches in and I still get a little excited pulling these out of the oven. Ham crisps at the edges, cheddar goes golden and bubbly right at 10 minutes. Cold out of the fridge Tuesday morning hits the same as fresh.
Cold from the fridge is how my kids eat them too. Never wait for warm. The ham gets a little chewier after a day in there and I think it's better.
I started making these on Sundays three weeks ago to stay ahead of school mornings, and the thing that got me was my youngest asking where they were on the one day I forgot to prep. This kid does not notice breakfast. He grabs a granola bar and is out the door before I've had coffee. Him noticing the missing muffin tin said more about how filling these are than anything. I run two batches now, 32 total, and they're gone by Thursday. The one adjustment I've made is letting the cheddar go a little golden, maybe a minute past when the eggs look set. Makes a difference.
That granola bar kid noticing the missing muffin tin is the best review this recipe's ever gotten. And yeah, that extra minute on the cheddar is real - the edges get almost crispy.
My mom used to press deli ham into a muffin tin and crack an egg on top every Sunday morning. I hadn't thought about that in probably fifteen years. Made this yesterday and it all came back.
Your mom had the method exactly right. This is basically just that with cheese. I still make a batch every Sunday too.
I kept seeing egg cups everywhere and always assumed they'd be one of those things that sounds clever in theory but disappoints in practice, like cauliflower pizza from a bag. Made these last Sunday as a test and the ham does something I genuinely didn't see coming. It crisps up around the edges into almost a little shell while the egg inside stays soft and custardy. I've tried the bell pepper ring version, the silicone mold version, paper liners, and they all had this same flat, slightly rubbery thing going on. These don't have that problem. Reheated three of them Monday morning in 45 seconds and they held up. Going to make a double batch this week and see if the freezer situation works out.
Silicone just doesn't get the sides hot enough. It's the tin. For freezing, wrap each one individually in plastic wrap and into a freezer bag. I've had them keep 3 months that way, same 45-second reheat.
Brought these to a work potluck last weekend. People picked them up expecting catered appetizers, and someone asked which bakery I'd ordered from. Funny, for three ingredients and 12 minutes in the oven. What really got me was a coworker who avoids eggs on principle, grabbed one to be polite, then came back for another without saying a word. The cups held their shape after 30 minutes sitting out, which is what actually matters when you're bringing food somewhere. I've switched to silicone because the release is cleaner and you can just peel the sides away. Four stars. I think cream cheese stirred into the egg before baking would push these over the top, but as written they're solid.
The egg-avoider coming back for seconds without saying a word is honestly the best possible outcome. On the cream cheese idea, I've stirred it into whisked eggs before and it works really well, haven't tried it with whole eggs cracked in but that's worth testing.
My daughter renamed these 'ham cups' after the first batch and that was apparently that. She is not a breakfast person, but she's been pulling two from the fridge before school every morning this week. The ham folded around the egg is what sold her, I think.
Ham cups is a better name. A non-breakfast kid pulling two before school every morning is my favorite kind of feedback.
Brought these to a spring brunch and the question I kept getting was 'what are those little ham cups?' They were gone before I even made it through the buffet line.
Hide a few before you set them out next time. I've lost my own food at too many potlucks to not do that now.
I've made probably four or five different keto egg cup recipes before landing on this one and most of them came out with that rubbery white-on-top situation where you can tell they weren't quite right. The ham lining is what I kept skipping in other versions thinking it was optional. It's not. The whole structure is different when it's actually there. Mine had these little crisped-up edges where the ham hit the muffin tin, and the egg set into the cup instead of puffing up weird. The cheese melted down through everything instead of just sitting on top, which sounds minor but it changed the whole bite. I pulled two from the fridge Tuesday morning before I'd even had coffee and that's when I knew this replaced my old standby. Three ingredients actually filling you up? Had to see it.
Yeah that crispy edge where the ham hits the tin is the best part. The whole thing collapses without it.
New to meal prepping, planning to try these this weekend. Quick question: when you say bake until the egg is set, does the yolk need to be fully solid or is a soft center fine? I'm reheating from the fridge each morning and wasn't sure if that changes things.
For meal prep, go fully set. A soft yolk reheats weird and can get rubbery before the whites are even warm. I pull mine when there's no jiggle at all.
