Mini Grilled Cheese Hawaiian Rolls

The scent of Hawaiian rolls always pulls me back to a game day gathering where my friend Sarah set down a tray of these golden little sandwiches. Within five minutes, they had vanished, and I spent the rest of the party tracking down who made them. Now they are my go-to when I need something that disappears just as quickly.

Last summer I made these for my nieces who usually complain about grilled cheese being boring. They watched through the oven door as the cheese bubbled up through the seams, and now whenever I visit they ask if the special little sandwiches are coming. That is how I know this recipe is a keeper.

Ingredients

• 1 package (12-count) Hawaiian sweet rolls: The sweetness in these rolls is what makes this recipe sing, so do not swap them for plain dinner rolls.
• 8 oz (225 g) cheddar cheese, sliced: Sharp cheddar cuts through the sweet rolls beautifully, though I have used pepper jack when craving extra heat.
• 2 tbsp (30 g) unsalted butter, melted: Brushing the tops with butter creates that gorgeous golden crunch everyone fights over.
• 1 tbsp (15 g) Dijon mustard: This optional addition adds just enough tang to wake up all the flavors without overwhelming the cheese.
• 1 tbsp (15 g) mayonnaise: Combined with mustard, it creates a creamy spread that keeps the rolls from getting soggy.
• 1 tsp garlic powder: Sprinkled on top, it gives these a savory note that makes people wonder what your secret ingredient is.
• 1 tsp dried parsley: Mostly for making them look restaurant pretty, though it does add a subtle fresh note.

Instructions

Get your oven ready:

Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper for easy cleanup later.

Prep the rolls:

Keep the rolls connected and slice the entire block horizontally to create one giant sandwich base.

Add flavor:

Whisk Dijon and mayo together if using, then spread evenly across both cut sides of the rolls.

Layer the cheese:

Arrange cheddar slices over the bottom half, then place the top half back on like you are reassembling a puzzle.

Butter and season:

Set the assembled block on your baking sheet, brush generously with melted butter, and sprinkle with garlic powder and parsley.

Bake covered:

Cover loosely with foil and bake for 10 minutes so the cheese melts without burning the tops.

Get them golden:

Remove foil and bake another 5 minutes until the tops turn golden brown and cheese is bubbling through the seams.

Finish and serve:

Let them rest 2 minutes before cutting into individual mini sandwiches, then serve warm.

Save

These little sandwiches have become my emergency contribution for everything from potlucks to unexpected guests. The best part is watching people hesitate, then reach for seconds and thirds when they realize just how good the combination is.

Making Them Your Own

The basic formula is incredibly forgiving. I have tucked cooked bacon or thin ham slices between the cheese layers, and once during tomato season I slipped in thin slices that made the whole thing feel gourmet. The sweet roll base handles almost any addition beautifully.

Serving Suggestions

While these hold their own as party appetizers, they also shine alongside a steaming bowl of tomato soup for a comfort meal. I have served them with a simple green salad for weeknight dinners when nobody wants to cook anything elaborate.

Make Ahead Strategy

You can assemble the entire sandwich block up to a day ahead, wrap it tightly in foil, and store it in the refrigerator. Just add a couple extra minutes to the baking time since everything will be cold going into the oven.

• Let the assembled block sit at room temperature for 15 minutes before baking if you have time.
• Wrap extras in foil and reheat at 300°F for 10 minutes to bring back that just baked texture.
• The baked sandwiches freeze beautifully for up to a month and reheat surprisingly well.

Save

Whether for a party or just a Tuesday night treat, these mini sandwiches have a way of making any meal feel special.

Recipe Q&A

→ Can I make these ahead of time?

Assemble the rolls up to 24 hours in advance, wrap tightly in plastic, and refrigerate. Add the butter coating just before baking.

→ What other cheeses work well?

Mozzarella creates extra meltiness, Swiss adds nutty depth, pepper jack brings spice, or try mixing multiple cheeses for complex flavor.

→ How do I store leftovers?

Keep refrigerated in an airtight container for 2-3 days. Reheat in a 350°F oven for 5-7 minutes to restore crispness and meltiness.

→ Can I freeze these before baking?

Yes, assemble completely with butter coating, wrap tightly in foil then freezer bags. Freeze up to 1 month. Bake from frozen, adding 5-10 minutes.

→ What can I add inside for more variety?

Cooked bacon, ham slices, tomato, spinach, caramelized onions, or jalapeños all complement the sweet-savory profile beautifully.
