Air Fryer Canadian Bacon Egg Cups (Keto)

Canadian bacon makes a better egg cup than regular bacon, and it took me a few messy batches to work out why. Regular bacon shrinks and slumps as the fat renders, so the cup collapses before the egg sets. Canadian bacon is lean and already cooked through — it holds its shape the entire time, which means you get a clean-edged cup with a properly set white and whatever yolk you like.

These are about 1 gram of carbs each and take roughly twenty minutes start to finish.

Why Canadian Bacon Instead Of Regular Bacon

This is the question I get most, so it’s worth answering properly.

Regular streaky bacon needs par-cooking before you shape it, or it won’t crisp in time. It also renders a lot of fat into the bottom of the cup. It works — I have a whole recipe for air fryer bacon and egg cups built around it — but it’s a different technique and a different result. Crispier, richer, more work.

Canadian bacon is cured pork loin, not belly. It’s lean, mildly sweet, and pre-cooked, so it goes into the tin raw-side-out and just warms through while the egg cooks. No par-cooking, no rendered fat, no shrinkage. If you’ve ever pulled a soggy-bottomed egg cup out of the air fryer, this is the fix.

One practical note: Canadian bacon will not get crisp the way streaky bacon does. It browns at the edges and firms up. That’s the ceiling, and it’s fine — it’s a ham, not a bacon, whatever the label says.

What You’ll Need

Full measurements are in the recipe card below.

• Canadian bacon — [note here how many slices per muffin well you needed, and the brand you buy]. Thickness matters more than you’d think; around ¼ inch is the sweet spot.
• Large eggs — one per cup.
• Salt and pepper — a pinch each. Canadian bacon is already well salted, so go light.
• Cooking spray — the eggs will stick without it.

Optional, and genuinely optional: a tablespoon of shredded cheese, or finely chopped spinach, peppers, or onion tucked under the egg. Keep additions small or they’ll release water and loosen the white.

For equipment you need a muffin tin that actually fits your basket. I use this one, that fits my 5 quart air fryer, I have been using it for years.

Silicone muffin cups also work and release more easily.

How To Make Air Fryer Canadian Bacon Egg Cups

Step 1: Grease the tin. Spray every well you’re using, including the sides.

Step 2: Line the wells. Press a slice of Canadian bacon into each one, working it down so it lines the bottom and comes up the sides. If a slice tears, overlap a second piece over the gap.

Step 3: Add the eggs. Crack one egg into each lined cup. Go slowly if you want the yolk intact.

Step 4: Season. A pinch of salt and pepper. Add cheese or vegetables now if you’re using them.

Step 5: Air fry at 300°F for 12–14 minutes. Preheat first — it matters for how evenly the whites set. Start checking at 10 minutes, because air fryers vary more than ovens do. (I used the Cosori Air Fryer and it took about 12 minutes)

Step 6: Rest for a few minutes before lifting them out. They firm up as they cool and release much more cleanly. Run a knife around the edge if they’re stubborn. Done is when the whites are opaque and set all the way to the center. The yolk is your call.

Getting The Yolk Right

Pull them at 10–11 minutes for a runny yolk that breaks over the bacon. Go the full 14 minutes for a firm, sliceable yolk that travels well.

If you like yolks handled precisely, the same logic drives my air fryer poached eggs and air fryer soft boiled eggs — it’s all about pulling them a minute or two before you think you should.

Are These Keto?

Yes. At roughly 1 gram of carbohydrate and 7 grams of protein per cup, these fit comfortably into keto, low-carb, and most low-calorie plans. The carbs come from the sugar in the cure on the Canadian bacon, so check your brand’s label if you’re counting closely — some are cured with more sugar than others.

For a whole-day approach, they slot nicely into my weekly meal plan.

Storing And Reheating

Refrigerate in an airtight container for up to 4 days. Reheat in the air fryer at 300°F for 2–3 minutes — the microwave works but makes the whites rubbery.

They freeze for up to 2 months. Freeze them in a single layer first, then bag them, and reheat from frozen for 5–6 minutes.

If you’re making breakfast for a crowd rather than for the week, my air fryer breakfast casserole scales better than these do.

Questions I Get Asked

Can I use regular bacon? Yes, but par-cook it first or the cup won’t hold. The bacon and egg cups recipe walks through that method.

Do I have to preheat? Yes. Without it the whites set unevenly and the edges overcook before the center is done.

My eggs came out watery. Usually too much added vegetable. Chop finer, use less, or sauté first.

Can I make these in the oven? 350°F for 15–18 minutes in the same muffin tin.

What do I do with the leftover Canadian bacon? It’s the same cut used in air fryer eggs Benedict and in a copycat Egg McMuffin, so a pack rarely goes to waste here.

How do I serve them? On their own, or alongside air fryer breakfast biscuits if you want something more substantial.
