Why You’ll Love It
Something magical happens when you turn eggbites into these delicious makeahead fluffy egg breakfast sandwiches.
This is the kind of meal prep recipe that feels like a gift from your past self.

One pan of baked eggs makes 12 sliders, so you can knock out nearly two weeks of breakfasts in one go.
It’s also incredibly adaptable. Keep it simple with melty American cheese for the littles, or dress it up with Gruyère, bacon, and caramelized onion jam for a grown-up twist that feels borderline fancy.
These eggbite sandwiches freeze beautifully and reheat like a dream, which makes them perfect for meal prep, road trips, postpartum snacks, or just those mornings when the coffee hasn’t quite kicked in yet.
No need for drive-thru eggs when you’ve got these golden, cheesy beauties ready to roll. So whether you’re planning ahead for back-to-school chaos or just trying to make your mornings easier, this recipe will earn a permanent spot in your breakfast rotation.
Ingredients & Substitutions
These breakfast sandwiches are made with simple ingredients that pack in flavor, texture, and cheesy comfort. Here’s what you need and a few ideas if you want to switch things up.
The beauty of this recipe is that the base egg bake is super versatile — and the sliders can be tailored to your family’s preferences. It’s a great way to use what’s in your fridge while still delivering a satisfying, protein-packed breakfast.
FOR THE SANDWICHES
- Eggs: The base of the bake — I used 10 large eggs, but you could do 12 if they’re on the smaller side.
- Cottage cheese: This is the magic ingredient for fluffy, cloud-like eggs. Use full-fat for richness or low-fat if preferred.
- Cheddar cheese: Adds sharpness and meltiness. You can swap in Colby jack, Monterey jack, or mozzarella if needed.
- Kosher salt & hot sauce: The salt enhances everything, and the hot sauce gives it a subtle kick. Totally optional but highly recommended.
- Nonstick spray: Helps the egg bake release easily from the parchment-lined dish. You could also brush the parchment with butter or olive oil.
- King’s Hawaiian Original Sweet Rolls: These sweet, soft rolls are perfect for breakfast sandwiches. Any slider bun will work, but Hawaiian rolls bring that signature touch.
TOPPINGS
- American cheese (for the kids): Classic, creamy, and melts like a dream — this is kid-friendly comfort food at its finest.
- Caramelized onion jam, bacon, Gruyère (for the adults): This combo adds salty, sweet, and savory flavors that elevate these sandwiches into something special. Don’t have onion jam? A little Dijon mustard or fig spread works too.
How to Make It
You’ll start by blending and baking the eggs, then assemble your sandwiches with a half-for-the-kids, half-for-the-adults method. It’s all done in one baking dish and makes breakfast prep feel like a breeze.
- PREHEAT THE OVEN: Preheat your oven to 350°F and prep a small oven-safe dish with a cup of water — this helps create steam which helps keep the eggs moist and fluffy as they bake.
- BLEND THE EGGS: In a tall bowl, add the eggs, cottage cheese, cheddar, kosher salt, and hot sauce (if using). Use an immersion blender to mix everything until smooth and airy.
- BAKE THE EGG MIXTURE: Line a 7x10.5-inch baking dish with parchment paper and spray it with nonstick spray. Pour in the egg mixture and place in the oven along with your water dish. Bake for 45 minutes.
- SLICE THE ROLLS: While the eggs bake, carefully slice the King’s Hawaiian rolls in half horizontally and set aside.
- BUILD THE SANDWICHES: Once the eggs are done and slightly cooled, place the entire slab on the bottom half of the rolls. Score the eggs so each sandwich can pull apart easily. On one half, layer on American cheese for the kids. On the other half, add Gruyère, caramelized onion jam, and crumbled bacon.
- TOP & CUT: Add the top half of the rolls, press gently, and cut the sandwiches into 12 portions using a sharp knife or bench scraper.
- FREEZE OR SERVE: Serve warm or wrap each sandwich in foil and pop them in the freezer. To reheat, just unwrap and warm in a toaster oven or microwave until heated through.
Reheating Tips
These sandwiches are made for busy mornings, which means reheating should be as simple as possible. Whether you’re pulling one from the freezer or the fridge, here’s how to get that melty, fluffy, just-made texture every time.
- From the fridge: These fluffy egg sandwich sliders reheat best when they're thawed in the fridge first. If you're starting from the freezer, just transfer them to the fridge the night before so they’re ready to go in the morning. When you’re ready to eat, place the foil-wrapped sandwich in the oven before preheating it to 350°F — this way they warm up together gradually. Check after 25–30 minutes. Alternatively, unwrap the sandwich, wrap it in a damp paper towel, and microwave on a plate for 30–45 seconds at a time until heated through.
- From the freezer: You can bake them straight from frozen at 350°F for about 45 minutes to an hour with the foil on, then uncover for the last 2–3 minutes to let the tops toast up. You can also microwave them by wrapping in a damp paper towel and heating for 1–1.5 minutes, but this method is definitely best saved for busy mornings when you're short on time as the sandwiches could get rubbery and chewy from the microwave.
- Pro tip: Reheating for the whole crew? Place a few foil-wrapped sandwiches on a baking sheet and warm them all together in the oven. Easy batch breakfast = unlocked.
What to Serve It With
These sandwiches are super filling on their own, but here are a few things you can serve with them for an easy breakfast spread:
- Fresh fruit or a fruit cup
- Hash browns or breakfast potatoes
- Yogurt with granola
- Cold brew or a smoothie
- Bonus: They make a great addition to brunch boards for hosting!
