Step-by-Step Instructions
Preparing the Sheet Pan
Before you begin assembling your s’mores casserole, it’s important to prepare your sheet pan. Start by lining a large sheet pan with parchment paper, ensuring it covers the entire surface. This will prevent the ingredients from sticking and make cleanup easier.
Layering the Ingredients
Begin by arranging the graham crackers in a single layer on the prepared sheet pan. Next, sprinkle half of the mini marshmallows evenly over the graham crackers, followed by half of the chocolate chips. Drizzle melted butter over the top to enhance the flavor and help everything meld together.
Repeat with another layer of graham crackers, marshmallows, and chocolate chips, ensuring that every corner of the sheet pan is covered.
Baking to Perfection
Preheat your oven to 350°F (175°C). Place the sheet pan in the oven and bake for 10 to 12 minutes, or until the marshmallows are golden brown and the chocolate is melted. Keep a close eye to avoid burning the marshmallows.
Remove from the oven and let cool slightly before serving. This will allow the casserole to set and make it easier to cut into portions.

Pro Tips
Crafting the perfect sheet pan s’mores casserole requires a few insider tips to ensure gooey success every time.
- For the ultimate gooey texture, slightly underbake the casserole and let it finish setting outside the oven.
- Serve the casserole warm for the best gooey marshmallow and melty chocolate experience.
- Store leftovers in an airtight container at room temperature for up to two days.
- If reheating, use a low oven temperature to avoid scorching the marshmallows.
The most important tip is to enjoy the process and have fun experimenting with different ingredients and flavors. After all, cooking is about creativity and enjoyment!
