Labour Day Grilled Antipasto Skewers with Charred Ciabatta Crostini
A crowd-ready Labour Day appetizer: marinated bocconcini, folded salami, charred bell peppers, blistered cherry tomatoes and mixed olives threaded on skewers. Served with quick grilled ciabatta crostini and a bright lemon‑herb olive oil for dipping, this recipe includes make-ahead marinades, exact grill timing for each component, and assembly tips so you can feed a backyard crowd without missing the party.
Ingredient Spotlight
Bocconcini (small mozzarella balls)
Bocconcini are small balls of fresh mozzarella cheese from Italy (traditionally Campania), soft and stored in brine. They have a delicate, milky flavor and a springy, tender texture that melts slightly when warm. Find them at supermarket deli/cheese counters, specialty Italian markets, or in the refrigerated cheese aisle; substitute with sliced fresh mozzarella, ciliegine (smaller fresh mozzarellas), or burrata for a richer option.
Ingredient Spotlight
Pitted mixed olives (e.g., Castelvetrano + Kalamata)
This indicates a mix of specific Mediterranean olives: Castelvetrano (an Italian green olive, buttery, crisp, and mild) and Kalamata (a Greek dark purple olive, meaty, tangy, and fruity). They provide contrasting textures and briny-sweet flavors that are common in Mediterranean dishes. You can find them in the olive/antipasti section or at olive bars in grocery stores and Mediterranean markets; if unavailable, substitute with a mix of green Manzanilla or Niçoise and a briny black olive (or use a single variety you prefer).
Ingredient Spotlight
Ciabatta loaf (large), sliced 1/2" thick
Ciabatta is an Italian rustic white bread with a thin, crisp crust and an open, chewy crumb produced from a high-hydration dough (originated in the Veneto region). Its porous interior soaks up olive oil and juices well, making it ideal for toasting or serving alongside salads and antipasti. You can buy it at bakeries, supermarket artisan bread sections, or make at home; good substitutes are country-style sourdough or a crusty baguette (though crumb and chew will differ).
Author's Note
"Perfect for backyard gatherings — assemble ahead or build a self-serve platter so guests can graze. The lemony marinade and grilled ciabatta keep these skewers bright and irresistible."
Labour Day Grilled Antipasto Skewers with Charred Ciabatta Crostini
Labour Day Grilled Antipasto Skewers are the kind of appetizer that lets you be social and practical at once: everything can be prepped, partially cooked, and then finished on the grill while you pour another drink. The backbone of the skewers is a play of textures and temperatures — creamy, lemony bocconcini that soak up a bright garlic‑oregano oil; smoky, silky strips of charred bell pepper; poppable, blistered cherry tomatoes; salty mixed olives; and thinly folded salami that adds a savory chew. A charred ciabatta crostini and a lemon‑herb dipping oil turn these bites into a shared, hands‑on experience that travels easily around a backyard party.
What makes this version work is the choreography: whole peppers go on the hottest part of the grill for quick blackening then steam in a bowl so peeling is effortless, while tomatoes only need a minute or two to blister and release sweetness. Marinating the bocconcini ahead concentrates flavor without turning them mushy if you reserve some oil and drain them briefly before threading. The recipe is forgiving — swap proportions, double up favorites, or pre‑assemble dozens on platters — but the small, intentional steps (char, steam, drain, skewer) are what keep each bite bright and balanced.

Tips from the kitchen
Dry Bocconcini Briefly
After marinating, let the bocconcini drain in a sieve for 5–10 minutes and blot gently with paper towel so they don't make skewers soggy.
Steam Peppers to Peel
Cover charred peppers immediately after grilling to steam; the trapped steam will loosen skins so you can peel them without losing flesh.
Use Grill Basket For Tomatoes
A grill basket or short skewers keeps cherry tomatoes from falling through the grates and makes it easy to turn them all at once.
Thread For Balance
Place heavier items like bocconcini and folded salami toward the middle of the skewer and an olive at the tip so skewers lie flat on a platter.
Reheat Crostini Fast
Keep crostini warm in a foil tent and refresh for 30–60 seconds on a hot grill if they soften before serving.
Variations & substitutions
Vegetarian Swap
Replace salami with grilled zucchini ribbons or marinated artichoke hearts and add a sprinkle of toasted pine nuts for more texture.
Spicy Calabrian Twist
Stir 1–2 tsp chopped Calabrian chile into the bocconcini marinade and brush crostini with a little chili‑infused oil for heat.
Vegan Version
Use firm tofu cubes or a store‑bought almond mozzarella substitute marinated the same way; skip the salami and swap in roasted mushrooms for umami.
Herbed Burrata Option
For a luxe finish, swap every other bocconcino for small quenelles of burrata just before serving so guests get a soft, creamy contrast.
Storage & make-ahead
Store marinated bocconcini in an airtight container in the fridge for up to 24 hours; reserve some marinade separately for the dipping oil. Assembled skewers are best eaten within 2 hours — moisture from the cheese and peppers makes them lose their crunch if refrigerated longer. Keep crostini in an airtight container at room temperature for up to 48 hours and re‑toast briefly before serving.
What to serve with it
Serve these skewers on large platters with shallow bowls of the lemon‑herb oil and extra lemon wedges for squeezing. Pair with a simple grilled corn salad or an arugula fennel slaw and a crisp white wine like Vermentino or a citrusy sparkling; for cocktails, an Aperol Spritz or dry gin and tonic complements the salty, smoky flavors. Arrange some extra marinated olives and a small bowl of caponata to stretch the platter for a larger crowd.
Frequently asked questions
Can I marinate the bocconcini longer than 24 hours?
I don’t recommend more than 24 hours; the cheese will absorb too much oil and lemon and become mushy and overly salty. If you need to plan further ahead, keep the bocconcini and marinade separate and combine them the day before.
How can I prevent the skewers from falling apart on the platter?
Thread ingredients snugly and place heavier items near the center of the skewer; lay skewers flat on a large board or use a shallow rimmed tray to keep them from rolling.
Can I make everything on a gas stove instead of a grill?
Yes — char peppers over a gas burner or under a broiler, blister tomatoes in a heavy skillet, and grill the ciabatta in a cast‑iron pan; the timing remains similar but watch closely to avoid burning.
Will the reserved marinade be safe for dipping?
Reserve a portion of the fresh oil before it contacts the cheese for the dipping oil; marinade that has been in contact with bocconcini should not be used for dipping unless boiled briefly to kill bacteria.
How do I scale this for a larger party?
Multiply ingredients and pre‑skewer as many as possible an hour before serving, keeping bocconcini chilled until 10 minutes prior; set up a serve‑yourself station so guests can grab skewers, crostini and oil while you mingle.
