Sandwich Pull-Apart Bread is basically a cheesy ham and mustard sandwich baked into a crusty sourdough loaf. It’s warm, savory, and a little sharp from the mustard in a way that keeps it from tasting flat.

I like this version because it has a creamy mustard spread inside the cuts and a garlic-butter glaze brushed over the top. You get crisp edges, melty cheese, and those little pockets where the bread soaks up all the good stuff.

For me, it’s best as a snacky dinner with a salad, or set out as a party appetizer when I want something that doesn’t need plates and forks. It’s also easy to tweak depending on what deli meat and cheese you already have.

Why You’ll Love This Recipe

Fast to throw together: Once the loaf is sliced, the rest is just spreading, tucking, and sprinkling. It’s the kind of recipe that fits into real life.

That deli-sandwich flavor: Ham, Swiss, Dijon, and mayo taste familiar in the best way, especially with the buttery crust.

Melty and crisp: The foil keeps the inside soft and hot, and the quick uncovered time gives you browned cheese and crisp corners.

Easy to customize: You can swap the meat and cheeses without changing the method. It’s a great “use what you’ve got” recipe.

Simple to serve: No slicing into neat pieces—people just grab what they want. It’s low effort once it hits the table.

Ingredients You’ll Need

Bread and fillings

Round sourdough loaf: I like a sturdy, crusty boule here so it holds its shape after all the cutting and filling. Softer sandwich bread tends to tear instead of making nice pockets.

Deli ham: Thin slices are easiest to tuck into the cuts. Honey ham is great too if you like a slightly sweeter bite.
Swiss cheese: Swiss is classic with ham and mustard, and it melts nicely without getting greasy. If you’re not a Swiss person, provolone works the same way.
Shredded mozzarella: This is the “glue” cheese that helps everything melt together. Pre-shredded is totally fine.

Dijon mustard: Dijon gives it that sharp sandwich flavor. If your Dijon is extra strong, use a lighter hand and add more mayo.
Mayonnaise: Mayo keeps the inside creamy and helps the mustard spread easily into the cuts. Plain, regular mayo is what I use.
Green onions: These add a little fresh bite without taking over. Slice them small so they don’t pop out when people pull pieces off.

Fresh parsley: It’s mostly for a fresh, herby finish. If you only have dried, I’d skip it and lean on the Italian seasoning in the butter.

Butter glaze

Unsalted butter: Butter is what makes the crust taste like garlic bread. Unsalted lets you control the salt, especially with salty deli meat.
Olive oil: A little olive oil keeps the butter from firming up too fast and helps it seep into the cuts. Any mild olive oil works.

Garlic: Fresh minced garlic is best here. Jarred garlic works, but it can taste a bit sharp, so I use a little less.
Italian seasoning: This keeps it simple and familiar—like a baked sub meets garlic bread. Use whatever blend you like.
Kosher salt: Just enough to season the bread. If your ham is very salty, you can cut this back.

Black pepper: A little pepper makes the cheese and mustard taste more “sandwich shop.” Freshly ground is nice, but not required.

Recipe Instructions

Preheat the oven: Heat the oven to 375°F and line a baking sheet with foil.
Cut the loaf: Cut the sourdough into a 1-inch crosshatch pattern, but don’t cut through the bottom crust. You want it to hold together like a loaf.

Spread the condiments: Spread the Dijon and mayonnaise down into the cuts using a small spatula or brush, so you get some in as many gaps as possible.
Add the fillings: Tuck the ham and Swiss into the cuts, then sprinkle the mozzarella over the top and into any open spaces. Finish with the green onions and parsley.
Mix the butter glaze: Stir the melted butter, olive oil, garlic, Italian seasoning, salt, and pepper together in a small bowl.

Glaze the bread: Drizzle and brush the butter mixture all over the loaf, letting it run into the cuts. Take a minute here so the top gets evenly coated.
Bake covered: Wrap the loaf loosely in foil and bake for 15 minutes.

Bake uncovered: Uncover and bake for about 5 minutes more, until the cheese is fully melted and the top is lightly crisped.

Rest and serve: Let it rest for 5 minutes, then pull apart and serve warm.

Some of my tips!

This is the part that really makes a difference. If you only read one section, make it this one because this is where I share the little trick that helps the recipe turn out so well.

Recipe Tips & Tricks

Use a crusty, sturdy boule. Softer loaves can collapse once they’re cut. A good sourdough round holds the fillings and stays chewy inside.

Don’t cut through the bottom. If the loaf gets sliced all the way down, it turns into a pile of cubes on the pan. I stop a little short and use a gentle sawing motion.

Spread the mustard and mayo deep. Getting the condiments down into the cuts is what makes it taste like a real sandwich instead of just cheesy bread. A small spatula or pastry brush makes it easier.

Go a little lighter on the fillings than you think. Big stacks of ham and cheese can force the cuts open and make the top bake unevenly. If your slices are thick, fold them and tuck smaller amounts into more gaps.

Keep an eye on dense loaves. Some sourdough rounds are tight and heavy, and they just need a bit longer covered so the heat gets into the center. If the cheese isn’t fully melted inside, cover it again and give it a few more minutes.

Make some touches!

There are plenty of easy ways to serve this depending on the occasion. Keep it simple, or add a few small touches to make it feel a little more special.

Serving Suggestions

Salad: I usually serve this with a chopped romaine salad or a simple arugula salad with lemon and olive oil. Something crisp is nice next to the cheesy bread.

Soup: A cup of tomato soup or roasted red pepper soup turns it into an easy dinner. The mustard and Swiss taste really good with a tomato-based soup.
Pickles: Dill pickles on the side (or sliced pickles added after baking) give it that deli-sandwich crunch. Banana peppers work too if you like a little heat.
Dips: A little extra Dijon, honey mustard, or even ranch on the side is great for dipping. I keep it simple and just put a small bowl next to the loaf.

Save it for later

This section covers how to store leftovers and what parts of the recipe you can prepare ahead of time.

Storage and Make Ahead

Store leftovers covered in the fridge for up to 4 days. I usually wrap the loaf (or the pieces) in foil so it doesn’t dry out as fast.

To reheat, warm it wrapped in foil at 350°F until it’s heated through. If you want the top crisp again, uncover for the last couple of minutes.

You can also assemble it ahead, wrap it well, and refrigerate it overnight. Bake it the next day, and plan on adding a few extra minutes to the covered bake time since it’s starting cold.

If you want it to last longer, freeze portions wrapped tightly in foil and tucked into a freezer bag. Thaw in the fridge overnight, then reheat in the oven until warm.

Recipe FAQs

What’s the best bread to use for pull-apart sandwich bread?

A crusty round sourdough boule is my favorite because it stays sturdy and doesn’t tear when you cut the crosshatch. Anything similar works too—just look for a loaf with a strong crust and a soft middle.

Can I swap the ham and Swiss?

Yes. Turkey, salami, or roast beef all work, and provolone, pepper jack, or cheddar are easy cheese swaps. I’d just stick with a good melting cheese so it doesn’t turn greasy.

Can I add pickles or peppers inside before baking?

I usually add them after baking, especially pickles, so they stay crunchy. If you bake them inside, they’ll soften and can make the bread a little wet in spots.

How do I know it’s done?

The top should look lightly crisped and the cheese should be fully melted down in the cuts, not just on the surface. If the inside still looks a little cool, cover it again and bake a few more minutes.

Before you go, take a look at a few other recipes below the recipe card. They use similar ingredients in a different way and are worth saving too.
