When it comes to party buffets, the easiest win is the DIY sandwich bar, hands-down. It works for summer parties when the weather is too hot for grilling, and it’s just as good for holiday gatherings when you don’t want to cook. Everyone assembles their own food, and you get to enjoy the company of your guests.
This buffet setup is also extremely customizable, so you can cater to a range of different dietary needs. Even a vegan sandwich bar is pretty easy to set up (just as long as you read labels carefully and talk to your vegan guests ahead of time to make sure you are buying the right products). Everyone assembles their own meals, so they get exactly what they want.
Here’s everything you need to know before setting up your DIY sandwich bar (plus, there are a few serving suggestions to go along with the guide too).
A Selection of Breads for the Sandwich Bar
The bread might be the single most important part of your spread, so be sure there’s some variety for your guests. Ciabatta rolls are a favorite because they can support lots of condiments and pickles without getting soggy. Croissants add a little fancy touch to a simple ham and cheese, and slider rolls are essential for kids and picky eaters. You can also add tortillas and large lettuce leaves for anyone who wants to create a lighter wrap for their meal.
Plan for about two pieces per person and make sure the slider rolls are clearly separate from the rest. You will want those for the kid-friendly station later.
The DIY Sandwich Bar: Proteins and Cheeses
Three to four deli meats is the sweet spot. Turkey and ham are always crowd pleasers. Add salami or pepperoni for the guests who want something with a little more flavor, and roast beef if your budget can allow it. Figure about three to four ounces of protein per person total, spread across however many varieties you put out.
For cheese, provolone, Swiss, and cheddar cover most preferences. If you want one thing that feels a little elevated without any extra effort, add fresh mozzarella. It pairs well with the Italian combo and it adds some extra visual interest to the spread.
Set Up a Signature Sandwich Display
If you want to be a little bit extra for your party, consider setting up a signature sandwich tray. This is a display that gives people some inspiration for the types of sandwiches they can build. Put two or three pre-made sandwiches with all the fixings on a serving tray, and label each one. Think of it like a dessert cart, where guests can see the possibilities before they start piecing together their sandwiches.
These combinations that work well for your signature sandwich display are:
The Italian: Salami, provolone, roasted red pepper, arugula, olive oil, and red wine vinegar on ciabatta.
The Club: Turkey, ham, cheddar, romaine, tomato, and mayo on a croissant.
The Classic: Ham, Swiss, mustard, and pickle on a ciabatta roll.
The Mediterranean: Turkey or salami, provolone, roasted red pepper, arugula, and a drizzle of pesto wrapped up in a flour tortilla.
Of course, be prepared for someone to grab one and eat it! This is totally fine. You can remake it or just let it slide.
The Sandwich Bar Toppings Station
Keep the main toppings bar full and clearly laid out so guests are not reaching over each other. Romaine or arugula, tomato slices, roasted red peppers, pepperoncini, red onion, pickles, and avocado or guacamole cover most preferences. An elegant tiered tray works great for this setup. You can keep meats on one tier, cheeses on a second, and then veggies on the third.
For spreads, set out mayo, yellow mustard, Dijon, pesto, Italian dressing, and olive oil with red wine vinegar. A chic condiment jar set keeps everything looking neat and elevated.
Think about the flow of the table before you set everything out. Breads first, then proteins and cheeses, then toppings and spreads at the end. That way guests move through the line without creating a bottleneck at the condiment station.

The Kid-Friendly Sandwich Station
A kid-friendly sandwich station is a great addition. Having some “safe” food options for kids who aren’t that adventurous when it comes to eating is something parents will thank you for. Here are just a few setup tips for the kids’ station.
Set up a separate, clearly labeled spot with slider rolls, plain turkey, plain ham, American cheese, plain lettuce, plain tomato, mayo, and yellow mustard. Plain white bread, creamy peanut butter, and jelly are welcome options for the pickiest eaters (but check with parents ahead of time in case there is a nut allergy that needs to be avoided). It’s also a good idea to have an extra package of slider rolls; some kids will only eat bread, and that’s okay too.
Label it something low-key like "Kids-Only Sandwiches" so kids know exactly where to go without it feeling like a separate kids table situation.
Simple Sides for Your Sandwich Bar
The sandwich bar handles the main event. For sides, the goal is the same: no cooking, minimal effort, maximum payoff. A few well-chosen additions make the whole spread feel complete without adding a single thing to your to-do list the day of the party.
Make-Ahead Pasta Salads
Pasta salad is the MVP of the make-ahead side dish world. You cook the pasta the night before, toss everything together, stick it in the fridge, and pull it out when guests arrive. It actually gets better overnight as everything marinates together, which means the one side dish that requires any real effort is already done before the party even starts.
A classic Italian pasta salad with rotini, salami, olives, pepperoncini, and Italian dressing is always a crowd pleaser and pairs naturally with the sandwich spread. If you want something a little different, a BLT pasta salad with bacon, cherry tomatoes, romaine, and a creamy dressing hits differently on a hot day.
And then there is the kid-friendly version, which deserves its own mention. Pasta, cubed cheddar, pepperoni, and Italian dressing. That’s it. No vegetables, no surprises, nothing to pick around. Kids go back for seconds and parents do not have to negotiate a single bite. Make a big bowl of it and watch it disappear.
No-Cook Dishes Worth Putting on the Table
Not everything needs a recipe. Some of the best party side dishes are fresh fruits, veggies, and cheeses with a few seasonings. This is as true for summer parties as it is for holiday celebrations.
Watermelon and feta: Cube the watermelon, crumble the feta, add a handful of fresh mint if you have it. This is more of a summer treat, but you can also pair feta with other fruits, including strawberries, peaches, pears, and figs.
Caprese skewers: Thread cherry tomatoes, fresh mozzarella, and basil onto small skewers, drizzle with olive oil, and arrange on a platter. They look like you spent actual time on them, even if you didn’t.
Fruit salad with honey-lime drizzle: Any combination of melon, berries, and stone fruit works here. A quick drizzle of honey and a squeeze of lime over the top adds a slight gourmet twist. Make it a few hours ahead and let it chill.
Coleslaw: Store-bought coleslaw mix dressed with a little apple cider vinegar, a spoonful of honey, mayo, and salt pulls together in five minutes and tastes like you made it from scratch.
Chips and dip: Hummus, guacamole, salsa, alongside a few bags of chips make a legitimate side dish at any party.
How Much Food to Buy for a Sandwich Bar
Scale everything per person and you can use this for a party of 8 or 25 without doing complicated math. Plan for two pieces of bread (or one roll) per person, three to four ounces of protein total across all varieties, and one to two ounces of cheese. For pasta salad, about half a cup per person as a side is a safe starting point, though if it is the kid-friendly version you might want to make more.
Toppings and condiments are harder to scale precisely, but a good rule of thumb is to buy one container or bunch of each and have a backup of anything you know your crowd goes heavy on. Get everything sliced at the deli counter, and ask for a thin slice. This makes the presentation prettier and makes it easier for everyone to build a perfect sandwich.
Why a DIY Sandwich Bar Works for Any Party
Once the spread is set up, the only thing you need to do is replenish some ingredients every once in a while and clear the table at the end of the party. I love the idea of a DIY sandwich bar for backyard parties, but it also works for football watch parties, Christmas lunches, and so many other events that require a slight catering touch.
