Step-by-Step Guide to Irresistible Sliders

Follow these simple, personalized steps to build the best pastrami sliders you’ve ever had. We’ve included tips to ensure they come out of the oven perfectly gooey and delicious.

1. Prep Your Pan and Rolls

First things first, preheat your oven to a cozy 350°F (175°C). Line a 9×13-inch baking dish with foil, leaving some overhang to make cleanup a breeze. Lightly spray the foil with cooking spray. Now for the rolls: without separating them, use a long serrated knife to slice the entire sheet of Hawaiian rolls in half horizontally, creating a top bun slab and a bottom bun slab. Place the bottom slab into your prepared dish.

2. Mix and Spread the Sauce

In a small bowl, whisk together the mayonnaise and ketchup until you have a smooth, pinkish sauce. It’s like a simplified Russian dressing. Spread this mixture evenly over the cut side of the bottom layer of rolls, getting all the way to the edges.

3. Layer on the Goodness

Now for the fun part—building your sliders! Quarter your cheese slices for easier distribution. Arrange two quartered slices of provolone cheese onto each individual roll section of the bottom bun slab. Next, pile on the pastrami, dividing the full pound evenly across the rolls. Follow this with two quartered slices of Swiss cheese on each, and top with two dill pickle slices per slider. Pro Tip: Don’t be shy with the pastrami! A generous pile is what makes these sliders truly satisfying.

4. Top and Butter the Buns

Place the top slab of Hawaiian rolls back on, lining it up with the bottom. In a separate small bowl, mix together the melted butter, poppy seeds, and garlic powder. Using a pastry brush, generously brush this savory butter mixture all over the tops of the slider buns. Make sure to cover every nook and cranny.

5. Bake to Golden, Melty Perfection

Cover the baking dish tightly with another piece of foil. This initial covered bake is crucial—it traps steam, which melts the cheese into a gloriously gooey state. Bake for 15-20 minutes, or until the sliders are heated through and the cheese is completely melted. For an extra golden, toasty top, remove the foil and place the sliders under the broiler for 2-3 minutes. Watch them like a hawk during this step, as they can go from golden to burnt in seconds! Serve immediately and enjoy the cheesy pulls.

Healthier Alternatives for the Recipe

• Better Buns: Swap the sweet Hawaiian rolls for whole wheat slider buns to add fiber.
• Sauce Swap: Use a light mayonnaise or even a Greek yogurt-based sauce for a healthier creamy element.

Serving Suggestions

These pastrami sliders are the star of any food spread. Pair them with classic sides to create a complete and satisfying meal.

• Game Day Feast: Serve alongside a big bowl of crispy potato chips, creamy coleslaw, and a tangy potato salad.
• Easy Dinner: Turn these into a weeknight meal by serving them with a simple side salad or some roasted broccoli.
• Party Platter: Arrange them on a platter with other easy appetizers, like our “Spicy Jalapeño Poppers” or “Crispy Baked Chicken Wings.”

Common Mistakes to Avoid

Based on data from hundreds of slider recipes, these are the most common pitfalls. Here’s how to ensure your sliders are flawless.

1. Soggy Bottoms: This happens from using too much sauce or not lining the pan. Stick to the recipe’s sauce amounts and always use a foil liner to create a barrier.
2. Burnt Tops: The broiler is powerful. If you choose to broil the sliders for that final toast, do not walk away. Two minutes is usually plenty.
3. Unevenly Melted Cheese: Covering the sliders with foil for the first part of the bake is essential. It traps heat and steam, ensuring the cheese melts evenly from the center to the edges.
4. Skimping on the Topping: The garlic butter topping isn’t just for show; it adds a ton of flavor and keeps the buns from drying out. Be generous when you brush it on.

Storing Tips for the Recipe

While these sliders are undeniably best when fresh from the oven, leftovers are still a treat if handled correctly.

• Storing Leftovers: Store any cooled, leftover sliders in an airtight container in the refrigerator for up to 2 days.
• The Best Way to Reheat: The microwave will make them soggy. To reheat, wrap the sliders in foil and bake in a 350°F (175°C) oven for 10-15 minutes, or until warmed through. This helps re-melt the cheese and keeps the buns soft.
• Make-Ahead Tip: You can fully assemble the sliders (without the butter topping) up to 4 hours in advance. Cover and refrigerate. When ready to bake, add the butter topping and bake as directed, possibly adding a few extra minutes to the bake time.

FAQs

Q1: Can I assemble these sliders ahead of time?

Yes! You can assemble the sliders completely, cover them tightly, and refrigerate them for up to 4 hours before baking. Just hold off on adding the melted butter topping until right before they go into the oven.

Q2: Can I use different kinds of cheese?

Absolutely. While the provolone-Swiss combo is classic, feel free to experiment. Muenster, cheddar, or Monterey Jack would all be delicious and melt well in these sliders.

Q3: What if I don’t have poppy seeds?

No problem! The poppy seeds are mostly for aesthetics. You can substitute them with sesame seeds for a similar look, or simply omit them. The garlic butter topping will still be delicious.

Q4: How do I prevent the bottoms of the rolls from getting soggy?

The best way is to not go overboard with the mayo-ketchup sauce. Spread a thin, even layer. Additionally, lining the pan with foil helps create a slight barrier, and baking them right after assembly prevents the sauce from soaking in for too long.

Q5: Can I freeze these sliders?

It’s not highly recommended, as the texture of the rolls and pickles can change upon thawing. They are best made fresh or refrigerated for a day or two. If you must freeze, it’s better to freeze them baked and wrapped tightly, then reheat from frozen in a covered, oven-safe dish.
