Batch Egg-White Muffins
One tray, twelve little muffins, a whole week of breakfast handled. Egg whites, soft veg and a touch of cheese baked into grab-and-go bites you box up on a Sunday and reach for half-asleep on a Wednesday. Two muffins land at about 120 calories and 18 grams of protein — a steady, honest start to the day with nothing to do at the counter when you’re tired.
Prep 01 / Batch of 12
For years my mornings were a small war I kept losing. I’d be up before the sun, kettle on, and somewhere between the first coffee and getting out the door I’d realise I hadn’t actually eaten anything with protein in it. A banana on the way to the gym, maybe. Then by ten o’clock I’m starving and grumpy and reaching for whatever’s nearest, which is never the thing I’d have chosen with a clear head. I don’t think I’m alone in that, love. Mornings are when good intentions go to die.
So one quiet Sunday I sat down and worked out how to take the decision out of it entirely. I wanted breakfast to be a thing I lifted off a shelf, not a thing I made. Eggs were the obvious answer — cheap, sturdy, full of good protein — but a fried egg doesn’t travel and it doesn’t keep. Baked into little muffins, though? They keep beautifully, they reheat in a flash, and a tray of twelve covers most of a working week. I leaned on the whites to keep the calories low and the protein high, kept a little cheese in for the flavour, and folded through whatever veg I had to hand.
Now I make a batch most Sundays without even thinking about it. I grab two on my way out, eat them warm or cold, and the morning war is just over. I’ve made these for tired parents, for shift workers, for a friend who swore she “couldn’t do breakfast” — and every one of them came back asking how I keep them from going rubbery. I’ll tell you that too. Make the tray once and you’ll see what I mean: a scary, scattered morning turns into lifting a lid. I’ve got you.
01Who it’s for & when to eat it
This is for the person who skips breakfast not because they want to, but because mornings are chaos. Bake one tray, box it, and the protein’s handled before the week even starts. Here’s how I steer the same twelve muffins depending on what you’re chasing.
Keep them lean
The base recipe is already a cut’s best friend — mostly egg whites and veg, very low calorie, very high protein for the count. Two muffins at 120 calories is a real breakfast you can build a deficit around. Load in extra veg for more volume and you’ll feel even fuller for the same numbers.
Fold in whole eggs
Swap a few of the whites for whole eggs and add a heavier hand of cheese. The protein climbs, the calories climb sensibly, and you get richer muffins that carry more energy into a busy morning. Eat three or four instead of two.
Steady morning fuel
A couple of these with a slice of wholegrain toast is a calm, dependable start — lean protein early, a little carb beside it, full energy without a heavy breakfast sitting on you. Even, repeatable, no fuss.
Timing: I eat mine first thing, two on the way out the door, but they’re not just a breakfast. A couple make a tidy mid-afternoon hit when the biscuit tin is calling, and they sit well before or after a session without weighing you down.
02Ingredients
Makes one tray — 12 muffins, 6 servings of 2. Each serving lands near 120 calories and 18g protein. Doubling up for a bigger crew? Run two trays and keep the proportions the same.

Swaps I actually use: any soft veg works — mushrooms, courgette, leftover roasted veg, all welcome, just chop them small and don’t overload the tin. No cheddar? Feta or a little parmesan brings the same savoury lift. Want it leaner still, drop the two whole eggs and the muffins hold fine, just a touch softer. For a dairy-free tray, leave the cheese out and lean on the smoked paprika and garlic to carry the flavour. Carton egg whites are perfect here and save you a pile of yolks.
03Step by step
Oven on, tin greased
Set the oven to 180°C (350°F). Brush a 12-hole muffin tin well with the olive oil — into every corner of every hole — or drop in silicone liners. Egg loves to stick, so this is the one step you don’t rush. Chop all your veg small while the oven comes up to heat.
Magnus says: grease like you mean it. A stuck muffin is a sad muffin.
Whisk the eggs and season
Pour the egg whites and the two whole eggs into a big jug or bowl. Add the grated garlic, smoked paprika, black pepper and a light pinch of salt, then whisk until it’s smooth and just a little frothy. A jug makes the pouring easy in a minute, so use one if you’ve got it.
Magnus says: a jug, not a bowl. You’ll thank me when you’re filling twelve holes.
Share out the fillings
Scatter the spinach, pepper, spring onion and cheese evenly across the twelve holes — about a tablespoon of filling in each. Top a few with a halved cherry tomato if you’re using them. Doing the veg first, then pouring the egg over, gives you an even spread instead of it all sinking to the bottom.
Pour the egg over
Pour the egg mixture over the fillings, leaving a little gap at the top of each hole — they puff as they bake. Give each one a quick poke with a fork so the egg settles around the veg. Twelve even pours means twelve even muffins, so take your time across the tray.
Into the oven until just set
Bake at 180°C for 18–22 minutes, until the tops are set and a touch golden and a knife comes out clean. Don’t push them too far — egg whites turn rubbery if you overbake them, so pull the tray the moment the centres stop wobbling.
Magnus says: just set is the goal. A minute too long and the bounce goes out of them.
Cool the tray, then fill your containers
Let the muffins sit in the tin for five minutes, then run a knife round each and lift them onto a rack to cool fully. Once they’re properly cold — not warm — pack them into containers in twos, lids on, into the fridge. Cooling first is what keeps them from sweating and going soggy in the box.
Magnus says: cold before the lid goes on. Trapped steam is the enemy of a good batch.
04The spec sheet
Real numbers, calculated — not guessed. The tray makes 12 muffins; a serving is 2, weighing roughly 120g. Here’s what one serving and a flat 100g actually give you. The headline is that protein-per-calorie number — it’s about as good as breakfast gets.
| Nutrient | Per serving | Per 100g |
|---|---|---|
| Energy | 120 kcal | 100 kcal |
| Protein | 18.0 g | 15.0 g |
| Carbohydrate | 3.2 g | 2.7 g |
| — of which sugars | 2.0 g | 1.7 g |
| Fat | 3.8 g | 3.2 g |
| — of which saturates | 1.8 g | 1.5 g |
| Fibre | 1.0 g | 0.8 g |
| Sodium | ~0.28 g | ~0.23 g |
Genuinely low. That’s what egg whites and veg do for you — a real, savoury breakfast that fills you up for a modest count. Perfect when you’re holding or losing and still want to feel fed in the morning.
This is the whole reason I make these. Fifteen grams of protein for every hundred calories is exceptional — almost everything you’re eating is doing protein’s job. For a grab-and-go breakfast, you won’t find much better.

05Bulk / Cut / TRT variations
One tray, three jobs. The egg-white base stays the same — you move the whole eggs, the cheese and the count around it. Macros below are per serving of 2 muffins, adjusted for each goal.
The lean default
All whites, light on the cheese, heavy on the veg. About as much protein as you can get for the calories, with extra volume from the vegetables to keep you full all morning. This is the version I lean on when the scale’s the priority.
Build it up
Swap half the whites for whole eggs and add a generous hand of cheese. Richer muffins, more energy, more protein. Eat three or four of these instead of two and you’ve a proper breakfast that pushes the day’s numbers up cleanly.
Steady & balanced
The standard tray, two muffins with a slice of wholegrain toast beside them. Lean protein early, a little carb to go with it, even energy through the morning without anything heavy sitting on you.
06Meal prep & storage
These were built to be made ahead, so storage is the main event. Cool them fully before they go anywhere near a lid, box them in twos so a serving’s already counted, and you’ve a week of grab-and-go breakfast sorted from a single tray.
Cooled and sealed, the muffins hold for a good five days. Bake a Sunday tray and you’re covered through Friday — two on the way out each morning, no thinking required.
They freeze brilliantly. Cool fully, freeze on a tray so they don’t clump, then bag them up. Pull out what you need the night before and thaw in the fridge, or reheat from frozen.
Microwave two muffins for 30–40 seconds, no more — egg goes rubbery if you blast it. They’re also genuinely good cold, straight from the box, if you’re truly out the door.
A small word on grab-and-go, because it’s the whole point: wrap a pair in a bit of foil or drop them in a small container the night before and leave it by your keys. The decision’s made while you sleep. That’s how a scattered morning becomes a calm one — the food is already waiting for you.

07Common questions
Why do my egg-white muffins go rubbery? +
Almost always overbaking. Egg whites firm up fast and then keep tightening, so the moment the centres stop wobbling and a knife comes out clean, the tray comes out. The same goes for reheating — 30 to 40 seconds in the microwave, no longer. Treated gently, they stay soft and tender; pushed too far, they bounce. Pull them early and you’ll never have a rubbery muffin again.
Can I use whole eggs instead of just whites? +
Absolutely. Whole eggs make a richer, softer muffin with more flavour and more fat — lovely if you’re not chasing the lowest calorie count. The reason I lean on whites is the numbers: you get nearly all the protein for far fewer calories, which is what makes these such a strong breakfast on a cut. Mix and match to suit your goal; the method doesn’t change a bit.
Do they freeze well? +
Really well — this is one of the best things about them. Cool them fully, freeze them spread on a tray so they don’t stick together, then bag them up for up to three months. Thaw a couple overnight in the fridge, or reheat straight from frozen for a minute or so. A full freezer of these means breakfast is sorted weeks ahead.
How do I stop them sticking to the tin? +
Egg is sticky stuff, so grease generously — brush oil into every corner of every hole, or use silicone liners, which lift out clean every time. Let the muffins rest in the tin for five minutes after baking, then run a knife around the edge of each before you lift them. Do that and they’ll come away whole.
Can I prep the mix the night before? +
You can. Whisk the eggs and seasoning, cover and keep in the fridge overnight, then chop your veg fresh in the morning or the night before too. Give the mix a quick stir before you pour, since it settles. That said, baking the whole tray takes barely half an hour, so I usually just do it all on a Sunday and box the finished muffins instead.
Do I have to eat them warm? +
Not at all — they’re genuinely good cold, straight from the box, which is half the appeal on a rushed morning. Warm them for half a minute if you’ve a moment and like them that way, but don’t feel you have to. Cold or warm, the protein’s the same; eat them however gets you out the door fed.
This prep is the backbone of a full week of meals.
