Breakfast Sandwich Wellington
This is a breakfast sandwich wrapped in golden, flaky puff pastry. Two sausage patties, marble cheddar, burger sauce, and a whole egg baked inside so it sets into a rich, jammy center. Finished with everything bagel seasoning. It eats like the best breakfast sandwich you've ever had, just in a format that makes people stop and stare before you slice it open.
Most breakfast sandwiches are good. A few are great (hint: my Potato Waffle Breakfast Burger is among the "great" crew, in my opinion). This one is in a different category entirely. Puff pastry wrapped around a full breakfast stack, baked until deeply golden, sliced open at the table to reveal a jammy whole egg in the center. It's the kind of thing that looks like it took serious skill and actually just takes patience and a good seal.
The idea came from the Cheeseburger Wellington, which already lives on this site and gets made in my kitchen more than I expected. This is that same concept applied to breakfast. Sausage patties instead of burger patties, marble cheddar, burger sauce, and then the move that makes this one its own thing: a whole raw egg cracked directly into the stack before sealing. It bakes into a set, jammy center that turns every slice into something genuinely special.
The everything bagel seasoning on the outside is not an afterthought. It gives the pastry a savory, seeded crust that ties the whole thing back to a classic breakfast sandwich flavor profile. If you're cooking this for people, plan for the moment you slice it. That's the whole payoff.

Why this Wellington works
The raw egg bakes perfectly inside the pastry. The key is keeping the stack centered and tight so the egg doesn't run before the pastry seals. A slight well pressed into the top sausage patty holds the egg in place. At 400°F for 25 to 30 minutes, the egg whites set fully and the yolk stays rich and jammy. It's the same principle as a baked egg in any enclosed vessel, just wrapped in butter-laminated pastry.
Two sausage patties create a stable structure. One patty is never enough to hold the stack upright and give the Wellington its shape. Two patties with the fillings sandwiched in between create a self-supporting column the pastry can wrap around cleanly. The cheddar on both sides of the filling acts as a moisture barrier, the same way it does in the Cheeseburger Wellington.
Everything bagel seasoning changes the whole experience. Applied generously to the egg-washed exterior before baking, it toasts into the pastry surface and gives you sesame, garlic, onion, and poppy seed in every bite of crust. It also signals immediately what this is: a breakfast sandwich, just in an unexpected format.
Resting before cutting is not optional. The egg continues to set in the residual heat after the Wellington comes out of the oven. Cut it too early and the yolk spills. Five to ten minutes of rest is the difference between a clean, impressive cross-section and a mess.

Ingredients
Method
- Cook the Sausage: Cook sausage patties in a skillet over medium heat until browned and fully cooked through. Set aside to cool slightly.
- Build the Base: Roll out puff pastry slightly if needed. Place one sausage patty in the center and layer with one slice of cheddar and a spoonful of burger sauce.
- Add the Egg: Gently press a slight well into the top of the sauce layer to help contain the egg. Crack one raw egg directly into the well. Season lightly with salt and pepper. Work carefully here to keep everything centered and contained.
- Finish the Stack: Lay a second slice of cheddar over the egg, then top with the second sausage patty. Press gently to stabilize.
- Wrap: Bring the puff pastry up and over the stack, folding and sealing tightly on all sides. Take your time here, any gap will let the egg escape. Flip seam-side down onto a parchment-lined baking sheet.
- Finish: Brush generously all over with egg wash. Coat the entire surface with everything bagel seasoning.
- Bake: Bake at 350°F for 30 to 35 minutes until deeply golden and cooked through.
- Rest and Serve: Rest for at least 5 to 10 minutes before slicing. This is the most important step. The egg finishes setting in the residual heat and the layers hold together cleanly when you cut.
Notes
- The sealing step is where most people run into trouble. The egg makes the stack slippery and the pastry wants to gap at the corners. Work slowly, use enough pastry to have real overlap at every seam, and pinch firmly. If a gap forms, press it closed with wet fingers before it goes in the oven.
- On the egg: the goal is a set white and a jammy yolk. At 400°F for 25 to 30 minutes, that's exactly what you get if the Wellington is properly sealed and the stack is compact. A looser stack with too much sauce or a thin pastry seal will let steam escape and the egg can overcook. Keep the fillings controlled.
- Burger sauce is worth making from scratch if you have 5 minutes. The version on this site is what I use here and it makes a real difference over store-bought. Just don't overdo the amount inside the Wellington... too much sauce and you'll get a soggy layer between the patties that works against the structure.
- If you want to make these ahead, build and seal the Wellingtons the night before and refrigerate unbaked. Pull them out 15 minutes before baking and apply the egg wash and seasoning right before they go in. Do not freeze them unbaked with a raw egg inside.

A breakfast wellington is a full breakfast stack wrapped in puff pastry and baked until golden. This version layers two sausage patties with marble cheddar, burger sauce, and a whole raw egg that sets into a jammy center during the bake. It's the breakfast sandwich format taken somewhere more impressive, without being significantly harder to make.
Yes, and it works better than you'd expect. The key is keeping the egg centered and contained inside the stack before sealing the pastry tightly. At 350°F for 30 to 35 minutes, the whites set fully and the yolk stays rich and just slightly jammy. Resting the Wellington for 5 to 10 minutes after baking lets the egg finish setting before you cut.
Two things matter most. First, cook your sausage patties fully before building so they don't release excess moisture inside the pastry. Second, keep the burger sauce amount controlled. Too much sauce creates a wet layer that steams the pastry from the inside. The cheddar on both sides of the filling acts as a barrier and helps protect the pastry walls.
At 400°F, plan for 25 to 30 minutes. The pastry should be deeply golden all over, not just lightly colored. The internal temperature should reach at least 165°F if you're checking. Rest it for at least 5 minutes before slicing so the egg sets cleanly.
Yes. Build and seal the Wellingtons the night before and refrigerate unbaked. Apply the egg wash and everything bagel seasoning right before baking. Don't apply the egg wash ahead of time or it will absorb into the pastry and you'll lose the shine and color. Do not freeze these unbaked since the raw egg inside doesn't freeze and thaw well.
