You hollow out a bagel, pour a cheesy egg mixture into the hole, and let the oven do everything else. That’s it, that’s the breakfast. These quiche stuffed bagels are about five minutes of actual work, they fill you up properly, and you can customize them a hundred different ways 🤯 I’m throwing these into my morning rotation for sure, because the only thing I want to do before coffee kicks in is pour something into something else.

What Makes These Quiche Stuffed Bagels So Good

You get the whole quiche experience without touching pie crust, a tart pan, or any of that. The bagel IS the crust. It goes crispy and chewy around the edge while the middle bakes into a soft, custardy egg full of melty mozzarella. Plus, because you scoop out some of the bready center, there’s room for a real amount of filling, so every bite’s got egg and cheese and bacon in it instead of just bread!

The texture is the sneaky-good part. That toasted bagel edge against pillowy baked egg is SO good, and then sriracha and fresh chives over the top cut through all of it. Is it a breakfast sandwich or is it a quiche? Both, and I’m not picking!

What Can You Put Inside a Quiche Stuffed Bagel?

Pretty much anything you’d put in an omelette. Picture your favorite egg dish and build a version of it right in the bagel. I went with bacon, bell pepper and mozzarella, but diced ham, sausage, spinach, mushrooms or a totally different cheese all work the same way. If you want another fun way to show off eggs, my tornado omelette drapes silky egg over furikake rice, though fair warning, that one is way trickier than pouring a filling into a bagel.

Tips for Making Quiche Stuffed Bagels

1. Leave a little bread in the base

When you hollow the bagel out, don’t dig all the way down to the crust. Leave a thin layer of bread in the bottom so the egg has something to sit on. Go gentle around the center hole because it gets flimsy fast, and if it cracks a bit it’s usually still fine, just pinch any tears shut before you pour.

2. Whisk the eggs properly

Whisk the eggs, milk and fillings until it’s one even mixture, so the filling bakes fluffy instead of dense. A spouted measuring cup makes pouring so much cleaner. If you’re an egg nerd like me, I go a lot deeper on this in my 15-second scrambled eggs, where a potato starch slurry is doing most of the work, but here a splash of milk is honestly all you need!

3. Do not overfill them

Fill each bagel to the top and no further. The custard puffs as it bakes, so an overfilled one will spill down the sides and weld itself to your pan. Two to three tablespoons per hole is about right, depending on how deep you dug.

4. Keep the egg and dairy balanced

If you want that classic quiche wobble, the ratio matters. The Kitchn’s quiche ratio guide puts it at about one egg per half cup of dairy for a silky custard. I lean this one eggier on purpose so the filling sets firm enough to pick up and eat with one hand!

Storage and Leftovers

These are great for meal prep. Let them cool, then keep them in an airtight container in the fridge for up to 3 days. Reheat at 350F in the oven or air fryer for a few minutes to bring the crispy edge back, or microwave one for about 30 seconds if you’re already halfway out the door!

You can also build them the night before, keep the filled bagels covered in the fridge, and bake them fresh in the morning. When I want a cold make-ahead egg breakfast instead, I go for my King’s Hawaiian tamago sando, which is a Japanese egg salad sandwich you can put together the night before. For a hot breakfast though, these bagels win every time.

Equipment

• Baking pan
• Spouted measuring cups
• Whisk
• Chef knife

Ingredients

• 2 bagels
• 4 Eggs
• 2 tablespoons whole milk
• 2 tablespoons bacon bits
• 3 tablespoons Shredded Mozzarella
• 2 tablespoons chopped bell pepper
• Salt and pepper, to taste
• Sriracha, to taste
• Chopped chives, to taste

Substitutions and Swaps

• The bagel. Plain, everything and asiago all work, and everything bagels are my pick because the seasoning toasts up and does half the flavoring for you! What I’d avoid is a soft, thin supermarket bagel, since it can’t hold the custard and collapses on you.
• The bacon bits. Diced ham, crumbled sausage or leftover chopped bacon all slot straight in. If you go with raw sausage, cook it first, because 20 minutes in the oven inside a custard isn’t enough to cook it through.
• The mozzarella. Any melty cheese is fine here, so cheddar, gruyere or provolone all pull their weight. Feta and goat cheese work too, they just won’t give you that stretchy pull.
• Going meat-free. Spinach, mushrooms and diced onion make a great version, but cook off the water first. Raw mushrooms or spinach release liquid into the custard and you end up with a soggy bagel bottom.
• The dairy. Half-and-half makes it richer and more custardy, and any unsweetened non-dairy version works fine. You only need 2 tablespoons, so this one barely moves the needle either way.

Instructions

1. Preheat the oven to 375F. Slice about 1/4 inch off the top of each bagel, then use a fork to carefully hollow out the middle, leaving a thin layer of bread in the bottom. Go gentle around the center hole so it doesn’t tear.
2. In a spouted measuring cup, whisk together the eggs, milk, bacon bits, cheese and chopped bell pepper, plus salt and pepper to taste.
3. Pour the mixture evenly into each bagel, filling to the top but not over.
4. Set the bagels on a small baking pan and bake for 20 minutes, until the egg is puffed and set in the middle.
5. While they bake, chop the chives.
6. Take them out, top with sriracha and chopped chives, and eat them hot.

What sells me on these is that they actually hold you until lunch. A lot of fast breakfasts don’t, and there’s enough egg and cheese packed into that bagel to do the job without asking anything of you.

It’s a good Sunday night move if your mornings are rough, since you can knock a few out at once and stop thinking about breakfast for a bit. 🙌

If you make these, leave a star rating on the recipe card and tell me in the comments what you stuffed yours with. It really helps other people find the recipe, and I’m always looking for a new combo to try!
