Reuben Bagel with Corned Beef and Cheese

Warm corned beef, tangy sauerkraut and melted Swiss cheese give this Reuben bagel plenty of character. Creamy dressing brings the layers together inside toasted bread with crisp edges and a chewy center. It is a sandwich worth sitting down for, especially while the cheese is still soft.

Savory beef, tangy cabbage and a creamy finish

Use fully cooked, ready-to-eat corned beef in thin slices for this bagel. Check the label when buying: raw corned beef needs a separate, complete cooking process before it can become this filling. Warm the cooked slices gently according to the package instructions, keeping them loose enough to heat evenly.

Sauerkraut brings acidity and texture. Let it drain well, then press out excess liquid gently so it will not soak the bread. Swiss-style cheese, such as Emmental, adds a mild, nutty flavor and a soft melted layer. Thin slices melt more readily than a thick slab.

Russian dressing or Thousand Island dressing gives the sandwich its creamy finish; a prepared dressing works well. Taste a little with the sauerkraut before filling, since the sweetness and sharpness vary between products. Spread enough to moisten the layers without letting sauce pool beneath them.

Warm the filling without drying the bagel

Toast the bagel halves until the edges are crisp, then arrange the cheese, warmed beef, drained sauerkraut and dressing in an even layer. Fold long meat slices back inside the ring. A manageable stack makes the sandwich easier to warm and bite through.

Finish warming gently until the cheese softens and melts, watching the bread so the edges do not become hard. If using a pan, a lid can help warm the top while you keep the heat modest. Serve hot. For pregnant people, adults 65 or older and anyone with a weakened immune system, heat deli meat to 165°F (74°C) or until steaming hot before serving.

Keep perishable filling ingredients at 40°F (4°C) or below until needed and refrigerate leftovers promptly. Discard food left unrefrigerated for more than 2 hours in total, or 1 hour above 90°F (32°C). If reheating properly chilled leftovers, check that the filling reaches 165°F (74°C) throughout with a food thermometer.

A hot sandwich with something crisp beside it

Homemade Bagels make a chewy base for the filling. That recipe shapes, briefly boils and bakes the rings; let them cool before slicing, then toast the cut sides for this sandwich.

Serve a Mixed Green Salad on the side for cool romaine, cucumber, pepper and corn against the warm beef and cheese. Its yogurt and white balsamic dressing adds a fresh tang. A pickle alongside is another simple choice if you want a smaller accompaniment.

Two useful finishing touches

• Shorten long cabbage strands: A few cuts through drained sauerkraut make it easier to bite through without pulling out the whole layer.
• Give the cheese room to melt: Tear the slices to fit around the bagel hole. Cheese hanging far over the edge can run into the pan before the center has softened.

An optional pastrami version

For a different meat filling, use fully cooked, ready-to-eat pastrami in place of the corned beef. Its seasoning changes the flavor, so taste it with the dressing before adding any extra pepper. Keep the drained sauerkraut and melting cheese for the same tangy, creamy combination.

Prepare the parts, assemble close to eating

Portion the cheese and cooked beef into covered containers in the refrigerator. Drain the sauerkraut ahead and store it separately from the dressing. With the filling organized, you can toast and assemble only the bagels you need. Store any leftover filling separately from the bread when practical; an assembled bagel softens as it sits.

Frequently asked questions

Why is the cheese still firm when the bread is already crisp?
The heat may be too high, or the cheese too thick. Use thin slices and warmed beef, then finish over gentler heat. A pan lid helps heat reach the upper layers.

Do I have to make the dressing myself?
No. Prepared Russian or Thousand Island dressing fits this sandwich. Taste the product with a little sauerkraut so you can judge how much you want in the filling.

Why does the bottom of my bagel turn soggy?
Excess sauerkraut liquid or too much dressing can collect underneath. Drain and gently press the cabbage before layering, use dressing sparingly at first and serve soon after warming.
