What You’ll Need to Make This Recipe
This recipe uses easy grocery-store ingredients, which is one reason it’s such a favorite when you need something quick and dependable.
Ritz Crackers
Ritz crackers are the perfect base here because they’re buttery, crisp, and just sturdy enough to hold the filling once warmed through.
Deli Ham
The ham brings that savory, slightly salty flavor that makes these sandwich bites feel hearty and satisfying.
Swiss Cheese
Swiss melts beautifully and adds a mild, creamy flavor that pairs especially well with ham and buttery crackers.
Butter, Dijon, and Worcestershire
This mixture gives the sandwiches that classic warm party-food flavor. It’s buttery, tangy, and full of savory depth.
Poppy Seeds and Dried Onion
These simple finishing touches add texture and flavor and give the tops that familiar, old-fashioned party sandwich look.

How to Make Ritz Cracker Party Sandwiches Step by Step
Step 1: Preheat the oven
Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish or line it for easier cleanup.
Step 2: Arrange the bottom crackers
Place half of the Ritz crackers in the baking dish, flat side down, creating the bottom layer for your mini sandwiches.
Step 3: Add the ham and cheese
Tear the deli ham into small strips and place some on top of each cracker. Cut the Swiss cheese into small squares or pieces and place one on each ham-covered cracker.
Step 4: Add the top crackers
Place another Ritz cracker on top of each one to make little sandwich stacks.
Step 5: Make the buttery topping
In a small bowl, stir together the melted butter, Dijon mustard, Worcestershire sauce, and garlic powder until smooth.
Step 6: Drizzle and finish
Drizzle the butter mixture evenly over the cracker sandwiches. Sprinkle the poppy seeds and dried minced onion over the top.
Step 7: Bake until warm and melty
Bake for about 15 minutes, or until the cheese is melted and the sandwiches are warm all the way through. Keep an eye on them so the crackers don’t get too dark.
Step 8: Cool slightly and serve
Let them rest for a couple of minutes before serving so they hold together a little better. Serve warm while the cheese is still soft and melty.
Expert Tips
- Don’t overload the filling or the crackers can slide apart.
- Cut the cheese small so it melts neatly without spilling everywhere.
- Drizzle evenly so all the sandwiches get that buttery flavor.
- Watch closely near the end because crackers can brown quickly.
- Serve warm for the best texture and flavor.
How to Store and Reheat Them
Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat in a low oven or toaster oven for a few minutes until warmed through and lightly crisp again.
They’re best fresh, but they can absolutely be made ahead and rewarmed for a party tray.
What to Serve With
- Pickles or a pickle tray
- Fresh veggies and ranch dip
- Fruit platter for contrast
- Hot soup for a cozy lunch plate
- Party snacks like chips, olives, or deviled eggs
Frequently Asked Questions
Can I use a different cheese?
Yes. Swiss gives that classic ham-and-cheese flavor, but cheddar, provolone, or mozzarella can also work.
Can I make these ahead of time?
Yes. You can assemble them in advance, cover, and refrigerate until ready to bake.
Will the crackers get soggy?
If they sit too long after baking, they can soften a little, which is why they’re best served warm not too long after coming out of the oven.
Can I use turkey instead of ham?
Absolutely. Turkey works well if you want a milder flavor.
Do I have to use poppy seeds?
No. They add a nice little finish, but you can leave them out if you prefer.
