Do you call these ham and cheese sliders or a ham and cheese sandwich casserole? I always think of sliders as mini-burgers but after the popularity of our Pizza Sliders recipe, I’m not so sure anymore.
Whatever you call it, this recipe is one of the most delicious things you can bring to a potluck or make for a crowd of hungry kids. I brought it to Miss G’s year end school celebration last year and the was the first one cleared!
Oh my gosh, just looking at those pictures now makes me want to stop everything and whip up a batch… but I’ll stick around long enough to give you the recipe… barely.
This recipe is a little bit different than most sandwich casserole recipes I’ve seen because while I’m all for butter, I think a recipe needs a bit more than just a generous coating of melted golden butter to achieve ultimate deliciousness. (Feel free to debate me in the comments!)
So, instead of just butter, I like to double-down on my fats with half butter and half olive oil, and bring in some savoury flavour with a bit of Worcestershire sauce and dijon mustard. (PS – I love that British tradition of adding a silent “shire” to the end of things. It’s like a good joke they play to see who the tourists are. You have to wonder how that goes down at spelling bees.)
You can definitely just use butter, but since listening to Gabrielle Hamilton’s Blood, Bones & Butter: The Inadvertant Education of a Reluctant Chef, I always hear her voice reminding me that two or three fats are better than one. (And in this case, the cheese can serve as the third fat.) This is a recipe that does well with slight modifications to make it better suit your personal tastes.
Ingredients for a Ham & Cheese Sandwich Casserole
- 1/3 butter
- 1/3 cup olive oil
- 2 Tablespoons Dijon mustard
- 2 teaspoon Worcestershire sauce
- 12 pack sandwich rolls
- 1lb sliced or shaved ham
- 1-2 cups mozzarella cheese, grated
- 2 teaspoons Italian seasoning
Tip: Substitute butter for the olive oil if desired, and swap out the spices and herbs however you’d prefer – maybe cajun seasoning or just salt & pepper. Use as little or as much cheese as you prefer.

How to Make Ham & Cheese Sliders
Preheat oven to 350F.
Place the butter, olive oil, mustard and Worcestershire sauce in a small saucepan over medium-low heat to melt as you prepare the sandwich casserole. Stir or whisk occasionally.
Slice the sheet of bread rolls in half across their middles so that the entire sheet opens like two big pieces of bread.
Spread a generous layer of shaved or sliced ham over the bottom half of the sliced bread rolls, covering them completely.
Then cover that ham with a complete layer of shredded cheese – you can be as sparse or as generous as you like.
Place the top half of the rolls overtop of the cheese and when the butter is completely melted, pour the melted mixture evenly overtop of the sandwich casserole.
You may need to brush the butter into place – or be prepared to melt a bit more butter to ensure the whole casserole gets covered. You don’t want any burnt sliders!
Sprinkle on the Italian seasoning and then cover and cook for 25-30 minutes.
