What You’ll Need for These Ritz Cracker Party Sandwiches
- Ritz crackers – Buttery, crisp, and slightly salty, these make the perfect sandwich base and top.
- Deli ham – Thinly sliced and torn into bite-sized pieces, ham adds a savory, meaty center.
- Swiss cheese – Melts beautifully and pairs well with ham, lending mild creaminess.
- Butter – Melted to coat the sandwiches, enhancing their rich flavor and helping them toast to perfection.
- Dijon mustard – Brings a tangy depth that cuts through the richness and keeps things interesting.
- Worcestershire sauce – Adds a savory, umami undertone to the glaze.
- Garlic powder – Subtle but essential, it builds flavor throughout.
- Poppy seeds – Sprinkled on top for texture and a slight nuttiness.
- Dried minced onion – Adds aromatic crunch and savory lift when baked.
Quick & Delicious: How to Make Ritz Cracker Party Sandwiches
Start by arranging half the crackers in a baking dish, then layer on torn ham and a small square of Swiss cheese. Top with another cracker to form a mini sandwich.
Whisk together the melted butter, Dijon mustard, Worcestershire sauce, and garlic powder, then pour it over the sandwiches, coating each one evenly.
Sprinkle with poppy seeds and minced onion, then bake until golden brown and melty. Serve them warm for best results—they’re gooey, crunchy, and absolutely addictive.
Easy Entertaining Tips for Ritz Cracker Party Sandwiches
These little sandwiches are endlessly adaptable. Swap the Swiss for cheddar or provolone, or use turkey or roast beef in place of ham. For a spicy kick, mix a dash of hot sauce into the butter glaze.
Make them your own by adding a slice of pickle, a dab of honey mustard, or a touch of cranberry sauce for seasonal flair. You can also prep them in advance and refrigerate before baking—just add a couple of extra minutes in the oven.

Storing & Reheating Leftovers with Style
If you happen to have leftovers (which is rare!), let them cool completely before storing in an airtight container in the fridge. Reheat in a 300°F oven for 5–7 minutes to restore their crispness and melt.
Freezing isn’t recommended for these, as the crackers tend to lose their texture. For the best results, enjoy these warm and fresh from the oven—just the way they’re meant to be.

Ritz Cracker Party Sandwiches
Ingredients
- 8 slices Swiss cheese
- 1/2 teaspoon garlic powder
- 1 teaspoon Worcestershire sauce
- 4 tablespoons butter melted
- 8 slices deli ham
- 1/2 teaspoon dried minced onion
- 2 teaspoons Dijon mustard
- 1 teaspoon poppy seeds
- 48 Ritz crackers
Instructions
- Preheat your oven to 350°F. Arrange 24 Ritz crackers, flat side down, in a 9×13-inch baking dish. Tear the deli ham into strips and fold a piece onto each cracker. Cut the Swiss cheese into roughly 1-inch squares and set a slice atop the ham-covered crackers. Cover each with a second cracker to create small sandwiches. In a small bowl, combine the melted butter with Dijon mustard, Worcestershire sauce, and garlic powder, whisking until uniform. Drizzle this mixture evenly over the sandwiches. Finish by sprinkling poppy seeds and minced onion across the tops. Bake for 10–12 minutes, or until the cheese is melted and the cracker tops are golden. Serve warm.
