Halloween, Pumpkin, Flatbread, Mozzarella, Grilled Pizza, Black Olives

Best for: A savory Halloween appetizer to slice and share.

Pumpkin makes a creamy, savory base for sweet onions and mozzarella on crisp grilled dough. Thin cheese strips form a spiderweb, with black olive spiders added at the end.

Grill: Two-zone, 400–425°F. Equipment: Grill-safe skillet, rolling pin, tongs, large spatula or pizza peel. Course: Appetizer.

Ingredients

Servings: 2 flatbreads (8 appetizer servings).Prep: 20 minutes

30–35 minutes Cooling: 2 minutes. Total: 52–57 minutes.

  • 1 pound prepared pizza dough, at room temperature
  • 1 tablespoon all-purpose flour, for rolling
  • 2 tablespoons olive oil, divided
  • 1 large yellow onion, thinly sliced
  • ¼ teaspoon fine sea salt, for onions
  • 1–2 tablespoons water, as needed for onions
  • ¾ cup plain canned pumpkin puree (not pie filling)
  • 2 tablespoons heavy cream
  • ½ teaspoon garlic powder
  • ½ teaspoon finely chopped fresh sage
  • ¼ teaspoon fine sea salt, for sauce
  • ⅛ teaspoon black pepper
  • 4 ounces low-moisture mozzarella, cut into thin strips
  • 8 large pitted black olives

Directions

Preheat the grill. Heat 1 tablespoon oil in a skillet over moderate direct heat. Cook onions with their salt for 20–25 minutes, stirring often, until softened and golden. Add a splash of water if sticking and shift to cooler heat as needed.

Stir pumpkin, cream, garlic powder, sage, sauce salt, and pepper together. Halve olives lengthwise; reserve 8 halves as spider bodies and slice the remaining halves into thin legs.

Divide dough in two. Roll on the floured surface into two roughly 10-inch thin ovals. Brush both sides with remaining tablespoon oil.

Grill dough over direct heat for 2–3 minutes until marked and firm enough to lift. Turn onto a board, grilled side up.

Spread each grilled surface with half the pumpkin sauce and onions. Arrange mozzarella strips into spokes and connecting rings to suggest a web. Return ungrilled side down over indirect heat; cover and cook 6–8 minutes until the bottom is crisp, dough cooked through, and cheese melted.

Transfer to a board. Arrange olive bodies and thin legs into spiders on top. Cool 2 minutes, then slice each flatbread into 4 portions.

Grilling tip: Keep the cheese strips thin and leave space between web strands; they spread as they melt.

Allergens: Wheat, milk; check dough.
