I love how quickly this comes together—just a handful of ingredients and a hot skillet and I’ve got something sweet, satisfying, and nostalgic. It’s like a dessert for breakfast, but still wholesome and just the right amount of indulgent.

ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

2 slices sturdy sandwich bread
2 tablespoons smooth or crunchy peanut butter
½ ripe banana, sliced
butter for grilling (or mayo for a golden crust)

directions

I spread peanut butter evenly on one slice of bread.
I layer the banana slices on top.
I close the sandwich with the other bread slice.
I butter the outside of both slices (or spread a thin layer of mayo).
I heat a skillet over medium heat.
I grill the sandwich until golden brown, about 2–3 minutes per side, using gentle pressure for an even sear.

Servings and timing

Servings: 1 sandwich (double the ingredients for more servings)
Prep time: 5 minutes
Cook time: 5 minutes
Total time: ~10 minutes

Variations

I mash the banana lightly into the peanut butter for a smooth texture.
I add a drizzle of honey or spread jelly for extra sweetness.
I try crunchy peanut butter or swap in Nutella for a chocolate twist.
I cook thin banana slices in butter before assembling to boost caramel flavors.

storage/reheating

I store leftover sandwiches in an airtight container at room temperature for up to a day.
To reheat, I pop it in a skillet over medium-low heat for a few minutes on each side until warmed and crisp again (microwave tends to make it soggy).

FAQs

What kind of bread works best?

I like sturdy sandwich bread (whole wheat or white) that crisps well without getting soggy. Brioche or sourdough also make it extra indulgent.

Can I make this ahead of time?

I can assemble it and keep it ungrilled in the fridge for a few hours. Just grill it fresh later for the best taste and texture.

Is it healthy?

I see it as a treat—peanut butter and banana bring protein and fiber, but it’s still a comfort food best enjoyed occasionally, especially if I use butter.

Can I freeze this?

I don’t usually freeze it—grilled sandwiches soften too much. But I could pre-assemble ungrilled, freeze it, and grill it from frozen (adding a bit of cook time) for convenience later.

How can I make it vegan?

I swap butter for plant-based margarine (or mayo alternative) and use a nut butter of choice. I check that the bread is vegan. Then it’s a plant-powered treat!

Conclusion

I love this grilled peanut butter banana sandwich because it’s so satisfying with minimal effort. Whether I keep it classic or fancy it up with honey, it’s a warm, nostalgic treat that hits the spot any time of day.
