How to make pastrami sliders
These slices are all about easy layering and baking until everything is warm and gooey.
- Preheat the oven to 350 degrees Fahrenheit. Line a 9 x 13-inch baking pan or dish with aluminum foil and spray with cooking spray.
- Keeping the buns together in one large piece, cut the rolls in half horizontally and place the bottom half in the pan.
- Spread the Russian sauce on the rolls. Layer of havarti slices, pastrami, swiss, and pickles.
- Add the top half of the rolls.
- Mix the melted butter with the poppy seeds and onion powder, then brush the surface.
- Cover with aluminum foil and bake for about 20 minutes, until warm and thawed.
- If you want browned tops, uncover and grill briefly. Warm service!

Recipe tips
- Use delicious pastrami, it is the main flavor here.
- Don’t overdo the pickles—just enough to add flavor without making the sliders slippery.
- Covering with foil helps everything heat evenly and keeps the surfaces from browning too quickly.
- Want crisper tops? Grill at the end for 30 to 60 seconds (watch closely to avoid burning).
- Refrigerate leftovers in an airtight container for up to 2 days. To reheat, heat in the oven at 325°F until heated through (best to keep cakes from getting soggy).
- The microwave works a little, but the cakes will cook.
- Use any leftover pastrami to prepare it Reuben hot sauce!

Easy differences
- Use provolone instead of Havarti for a milder melt.
- Replace Russian dressing with Thousand Island dressing or creamy French dressing.
- Use rye slider buns if you can find them (deli style!)
- Add a layer of sauerkraut to Robin– Slider inspired.
- Add spicy mustard for extra bite.

Cover brush (Spread the topping on the slices)
Preheat the oven to 350 degrees Fahrenheit. Line a large 9×13-inch baking pan or casserole dish with aluminum foil and spray the bottom with cooking spray.
As a single unit, cut rolls in half horizontally. Place the bottom half of the rolls in the prepared tray.
Spread the Russian sauce on the rolls. Arrange the Havarti slices on top, then arrange the pastrami slices on top of the Havarti, then arrange the Swiss cheese on top of the pastrami, and finally arrange the pickle slices on top of the Swiss. Place the top half of the rolls on top.
In a small bowl, mix together the melted butter, poppy seeds, and onion powder, then spread over the rolls.
Cover the rolls with aluminum foil and bake until warm throughout and the cheese has melted, about 20 minutes. If necessary, remove foil and broil after baking to brown the surfaces. Serve warm.
- Cover with aluminum foil while baking so the slices heat evenly and the cheese melts without over-browning the surfaces.
- For extra golden peaks, grill them briefly at the end (watch closely!).
- Leftovers are best reheated in the oven so the cakes remain soft but not soggy.
- Thousand Island dressing or creamy French dressing can be substituted for the Russian dressing, if necessary.
