Corned Beef On Rye Bagel + Schmear Box Recipe

Prepare bagels

Preheat a toaster or oven to medium heat (350°F / 175°C). Split the rye bagels in half. Lightly butter the cut sides of each bagel.

Toast bagels cut-side down in the toaster or on a sheet pan in the oven until golden and slightly crisp, 3–6 minutes. Remove and keep warm.

Cream cheese base

Place the cream cheese in a small bowl and soften with a spoon or rubber spatula until smooth and spreadable, about 1–2 minutes.

Make two spread options: For Classic Cream Cheese Schmear, keep half of the softened cream cheese plain (4 oz). For a zesty schmear, to the remaining 4 oz cream cheese add 1 tbsp Dijon mustard and 1 tsp prepared horseradish; mix until uniform.

Combine the whole-grain mustard and mayonnaise in a separate small container to create a mustard-mayo spread; stir until smooth. If you like sweeter notes, whisk in 1 tsp honey to a portion of the mixture.

If the corned beef is cold from the fridge, fold or pile slices and warm gently: place the sliced corned beef in a microwave-safe dish, cover loosely with a damp paper towel, and microwave in 20–30 second bursts until just warm (do not overcook). Alternatively, warm in a skillet over medium-low heat for 1–2 minutes, pressing lightly to heat through.

If using cheese, place a slice on the warm corned beef for 10–20 seconds to soften/melt slightly.

While bagels toast, arrange the thinly sliced red onion, sliced tomato, lettuce leaves, and pickles on a small tray or container for easy box packing.

Season tomato slices lightly with a pinch of coarse black pepper if using.

On each toasted bagel bottom, spread a generous layer (about 1 tbsp) of the plain cream cheese schmear. On each bagel top, spread the mustard-mayo mixture or the zesty cream cheese schmear—offer variety by alternating spreads between sandwiches.

Pile approximately 4 oz (about 1/4 lb) of sliced corned beef onto each bagel bottom (for 4 bagels total use the full 1 lb); if using cheese, place cheese on top of the corned beef. Add lettuce, 2–3 rings of red onion, and 1–2 tomato slices per sandwich as desired. Add 1 dill pickle spear or several slices on the side or inside the sandwich.

Cap sandwiches with bagel tops. Press lightly to compact.

If assembling as a box for later eating, pack sandwiches in a lined food box or container separated by parchment paper to keep pieces from sticking. Place extra small containers (2–3 oz) of the remaining plain cream cheese, zesty schmear, and mustard-mayo on the side for dipping or extra spreading.

Include the remaining pickles, extra onion rings, and any additional condiments in separate small containers. Add a small napkin and utensils if required. For best quality, consume within 4–6 hours refrigerated; if packing for longer, keep chilled with an ice pack.

Serve immediately if possible. Leftover components (extra schmear and corned beef) can be refrigerated up to 3–4 days; reheat corned beef gently before serving.
