Muffaletta sandwiches have always had a spot in my heart (and stomach). There’s just something about that New Orleans combination of zesty olive salad, layers of ham, salami, mortadella, and melty provolone.

What Ingredients You Will Need

This Muffaletta Sandwich Slab Pie uses simple, flavorful ingredients that bring the bold, briny, and savory flavors of the classic New Orleans muffaletta into an easy-to-share slab pie. Most of these are pantry or deli staples, and you can swap a few things if needed!

• For the crust:
  • 2 sheets refrigerated puff pastry (thawed, about 450g total) – (or use homemade pie dough for a flakier finish)
  • 1 egg, beaten (for egg wash, gives a golden crust)
• For the olive salad:
  • 1 cup (150g) mixed green and black olives, pitted and roughly chopped
  • 1/4 cup (40g) roasted red bell peppers, diced
  • 2 tablespoons (30ml) capers, drained
  • 2 tablespoons (30ml) pepperoncini, chopped (for a little heat)
  • 1/4 cup (60ml) extra-virgin olive oil
  • 2 teaspoons (10ml) red wine vinegar
  • 1 garlic clove, minced
  • 1/2 teaspoon dried oregano
  • Salt and black pepper, to taste
• For the filling:
  • 6 oz (170g) sliced provolone cheese – (or mozzarella, for a milder flavor)
  • 6 oz (170g) sliced salami
  • 6 oz (170g) sliced ham
  • 4 oz (115g) sliced mortadella – (can sub with more ham or turkey if needed)
  • 6 oz (170g) sliced Swiss cheese
  • 1/4 cup (15g) chopped fresh parsley (optional, for freshness)

Ingredient Tips: I like to use small-batch Italian olives for the best briny punch—Mezzetta is a good brand. If you’re not a mortadella fan, just sub in extra ham or even turkey for the same savory effect. For a lighter version, you can use part-skim cheese and low-sodium deli meats. The olive salad is really what makes this Muffaletta Sandwich Slab Pie pop, so don’t skimp on it! If you’re in a rush, some stores sell premade muffaletta olive salad in jars—no shame in that shortcut.

Equipment Needed

• Baking sheet (13×9-inch or similar): The slab pie needs space to spread out. I use a rimmed sheet to catch any cheesy bubbles.
• Parchment paper: Makes removing and slicing the pie so much easier (and cleanup is a breeze).
• Sharp knife or pizza cutter: For neat, even slices. I’ve found a pizza wheel actually works best for this!
• Mixing bowls: You’ll want one for the olive salad and one for the egg wash.
• Measuring cups & spoons: For accuracy, especially with the olive salad.
• Pastry brush: For the egg wash—if you don’t have one, just use clean fingers or a small spoon.

No fancy equipment here—just basic kitchen tools. If you don’t have parchment, generously grease your baking sheet. For the crust, I’ve used both store-bought and homemade dough; both work great. If you’re on a budget, Aldi’s puff pastry and deli meats deliver solid results without breaking the bank. Just be sure to keep your puff pastry cold until you’re ready to assemble for the flakiest layers!

How to Make Muffaletta Sandwich Slab Pie

1. Preheat and prepare your baking sheet:
   Preheat your oven to 400°F (200°C). Line a 13×9-inch baking sheet with parchment paper. If you don’t have parchment, lightly grease the sheet.
2. Make the olive salad:
   In a medium bowl, combine 1 cup (150g) chopped olives, 1/4 cup (40g) roasted red peppers, 2 tablespoons (30ml) capers, 2 tablespoons (30ml) chopped pepperoncini, 1/4 cup (60ml) olive oil, 2 teaspoons (10ml) red wine vinegar, 1 minced garlic clove, and 1/2 teaspoon oregano. Season with salt and black pepper to taste. Stir well, then set aside to let the flavors mingle.
3. Roll out the pastry:
   On a lightly floured surface, gently roll out one sheet of puff pastry into a rectangle (about 13×9 inches/33x23cm) to fit your baking sheet. Lay it on the prepared sheet. Keep the second sheet chilled until ready to use.
4. Layer the fillings:
   Spread half the olive salad across the bottom crust, leaving a 1/2-inch (1.25cm) border around the edges. Next, layer half the provolone, salami, ham, mortadella, and Swiss cheese, then scatter half the parsley. Repeat with the remaining olive salad and meats/cheeses, ending with parsley on top.
5. Top with second crust:
   Roll out the second sheet of puff pastry to the same size as the first. Carefully place it over the filling. Press the edges together and crimp with a fork to seal. Don’t worry if it’s not perfect—it’ll bake up beautifully!
6. Egg wash and vent:
   Brush the top crust with the beaten egg. Cut a few small slits in the top to let steam escape. This helps prevent a soggy crust.
7. Bake:
   Bake on the middle rack for 25-30 minutes, or until the crust is deep golden brown. Rotate the pan halfway through for even browning.
8. Cool slightly and slice:
   Let the pie cool on the sheet for 10-15 minutes before slicing. This helps the cheese set a bit and makes for cleaner cuts. Use a pizza cutter for best results.
9. Troubleshooting tips:
   If the crust browns too fast, tent loosely with foil. If the filling leaks, don’t stress—it just means extra crispy edges! If using homemade dough, bake a few extra minutes to get that deep golden color.

Pro tip: Assemble the pie up to a day ahead, cover tightly, and refrigerate. When ready to serve, bake as directed—no one will guess it was made in advance!

Cooking Tips & Techniques

• Keep pastry cold: Work quickly with puff pastry so it stays cold and puffs up beautifully. If it gets too soft, pop it in the fridge for 10 minutes before baking.
• Layer evenly: Spread the fillings in even layers to avoid soggy or empty spots. I’ve learned the hard way that bunching meats in one spot leads to uneven baking.
• Egg wash matters: Don’t skip the egg wash—it gives that irresistible golden crust. I once forgot, and the pie looked pale and sad (still tasty, but not Pinterest-worthy).
• Don’t overfill: Resist the urge to pile on too much filling, or you’ll have trouble sealing the edges. If a little leaks out, it’s okay—those crispy bits are chef’s treat!
• Use a pizza cutter for slicing: Seriously, this makes serving so much easier and keeps the layers intact.
• Multitasking tip: While the pie bakes, set out drinks or prep a quick salad. The Muffaletta Sandwich Slab Pie is the main event, but it’s nice to have something fresh on the side.

In my early slab pie days, I packed in too much olive salad and the bottom crust got soggy. Now, I drain the olive salad a bit before spreading and keep the layers balanced. Don’t be afraid to experiment—this recipe is forgiving. If you follow these little tricks, you’ll get a pie that’s crispy, cheesy, and packed with big, bold flavor every single time.

Variations & Adaptations

• Gluten-Free: Use a gluten-free pie dough or puff pastry. Most major grocery stores carry one now. Just watch the baking time—GF crusts can brown a little faster.
• Vegetarian: Swap the meats for layers of grilled eggplant, zucchini, and roasted red peppers. Add extra cheese or a smear of pesto for richness. My cousin is veggie, and she swears this version is even better than the original!
• Spicy Muffaletta: Add hot soppressata or spicy capicola in place of regular salami and ham. Toss in extra pepperoncini to kick up the heat. We love this for game day.
• Low-Carb: Use a low-carb wrap or dough as the crust. The filling is already pretty protein-rich, so it’s easy to adapt for keto or low-carb diets.
• Mini Muffalettas: Cut the pastry into squares and make individual hand pies. Bake for 18-20 minutes. These are great for grab-and-go parties or lunchboxes.

For a fun twist, I sometimes add a thin layer of grainy mustard between the meats and cheese. If you’re avoiding certain allergens, swap out cheeses or use turkey for the meats. Don’t be shy—make this Muffaletta Sandwich Slab Pie your own!

Serving & Storage Suggestions

This Muffaletta Sandwich Slab Pie is best served slightly warm or at room temperature—perfect for buffet tables or laid-back gatherings. Slice into squares or rectangles for easy serving. I love to pile the pieces high on a rustic wooden board for that cozy, shareable vibe.

If you want to go all-out, serve with a crisp green salad, a bowl of kettle chips, and cold lemonade or a light beer. For a fancier spread, pair with sparkling water and a charcuterie board.

Leftovers? No worries! Store slices in an airtight container in the fridge for up to 4 days. To reheat, just pop a piece in a 350°F (175°C) oven for about 10 minutes or until warmed through. You can also freeze individual slices—just wrap tightly and reheat as needed. Honestly, I think the flavors get even better the next day as everything melds together.
