Copycat Costco Pepperoni Pizza Slice Recipe – Giant, Cheesy, and Crispy at Home

If you’ve ever grabbed a massive, foldable slice from the Costco food court and thought, “I wish I could make this at home,” you’re in the right place. This recipe brings you that signature chewy crust, tangy-sweet sauce, bubbly cheese, and crispy pepperoni edges. It’s simple, big, and totally satisfying.

You don’t need fancy tools—just a hot oven and a large baking sheet or pizza stone. Whether you’re feeding a crowd or craving a late-night slice, this is the pizza you want.

Why This Recipe Works

• High hydration dough gives you a chewy, airy crust that stays tender in the middle and crisp at the edges.
• Low-moisture mozzarella plus a touch of provolone nails that stretchy, bubbly cheese pull you expect from a food court slice.
• Simple, no-cook sauce keeps the flavors bright and balanced without weighing down the crust.
• Heavy on the pepperoni delivers those crispy, cupped edges and savory drips that season the cheese as it bakes.
• Hot bake on a preheated surface ensures fast oven spring and a golden underside, just like the big slices you remember.

Ingredients

• For the dough (makes two 16-inch pizzas or four oversized slices each):
  • 3 1/4 cups (400 g) bread flour
  • 1 cup + 3 tbsp (285 g) warm water, about 100–105°F
  • 2 tsp (8 g) fine sea salt
  • 1 1/2 tsp (5 g) instant yeast
  • 1 tbsp (12 g) sugar
  • 1 tbsp (15 g) olive oil, plus more for the bowl
• For the sauce:
  • 1 can (14–15 oz) crushed tomatoes or tomato puree
  • 1 1/2 tsp sugar
  • 1 tsp kosher salt
  • 1 tsp dried oregano
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1 tbsp olive oil
• For the toppings:
  • 12–14 oz low-moisture whole milk mozzarella, shredded
  • 3–4 oz provolone, shredded (optional but recommended)
  • 5–6 oz pepperoni, sliced (about 45–55 slices)
  • 2–3 tbsp grated Parmesan
  • Cornmeal or semolina for dusting (optional)

Instructions

1. Make the dough. In a large bowl, whisk flour, salt, yeast, and sugar. Add warm water and olive oil. Stir with a spoon until a shaggy dough forms. Switch to a damp hand and fold the dough over itself for 1–2 minutes until mostly smooth.
2. Rest and develop gluten. Cover and rest 10 minutes. Perform 3–4 stretch-and-folds around the bowl. Rest 10 more minutes and repeat once. The dough should feel tighter and smoother.
3. First rise. Lightly oil the bowl, cover, and let rise at room temp until doubled, about 60–90 minutes depending on your kitchen.
4. Divide and cold proof. Turn dough onto a lightly oiled surface. Divide into two equal balls (about 345–360 g each). Tighten into smooth rounds. Place in oiled containers, cover, and refrigerate at least 8 hours, up to 48 hours. This improves flavor and texture.
5. Make the sauce. Stir tomatoes, sugar, salt, oregano, garlic powder, onion powder, and olive oil in a bowl. Taste and adjust salt or sugar. No cooking needed.
6. Preheat the oven. Place a pizza stone, steel, or inverted heavy baking sheet on the middle rack. Preheat to 500–525°F for at least 45 minutes so the surface is blazing hot.
7. Prep cheese and pepperoni. Shred mozzarella and provolone.Pat pepperoni dry with a paper towel to help it crisp.
8. Shape the dough. Remove one dough ball from the fridge and let it warm 30–45 minutes. Dust a peel or parchment with a little semolina or cornmeal. Gently press the dough into a 12–16 inch round, leaving a slightly thicker rim. Avoid using a rolling pin to preserve air bubbles.
9. Sauce it right. Spread 1/2 to 2/3 cup sauce in a thin, even layer. You should see some dough through the sauce—too much will make it soggy.
10. Cheese then pepperoni. Sprinkle an even layer of mozzarella and provolone, going almost to the edge. Top generously with pepperoni, slightly overlapping so it cups and crisps.Finish with a light dusting of Parmesan.
11. Bake. Slide the pizza onto the hot stone/steel (use parchment if needed). Bake 8–12 minutes until the crust is deeply golden, cheese is blistered, and pepperoni edges are crisp. Rotate once for even browning.
12. Finish and slice. Let rest 2–3 minutes. If you like that food-court sheen, brush the rim lightly with olive oil. Cut into large triangular slices—four oversized slices per pie nails the Costco vibe.
13. Repeat. Shape and bake the second dough ball with the remaining toppings, or refrigerate the dough up to 24 more hours.

Keeping It Fresh

• Short-term storage: Cool slices completely, then wrap individually in foil or store in airtight containers for up to 3 days in the fridge.
• Freezing: Freeze slices on a sheet pan until solid, then transfer to freezer bags. Keeps well for up to 2 months.
• Reheating: For best results, reheat slices on a hot skillet over medium heat 3–5 minutes, then tent with a lid for 1–2 minutes to melt the cheese. Or bake at 450°F for 6–8 minutes on a preheated sheet.
• Avoid the microwave unless you’re in a rush—it makes the crust rubbery.

Benefits of This Recipe

• Big-slice payoff: You get that oversize, foldable slice without leaving home.
• Budget-friendly: Pantry staples and basic cheese deliver maximum flavor without premium ingredients.
• Make-ahead friendly: Dough improves in the fridge, letting you plan for parties or weeknights.
• Customizable: Adjust sauce sweetness, cheese blend, or pepperoni amount to match your memory of the original.
• Consistent results: The method focuses on dough hydration, preheating, and layering—key steps that are easy to repeat.

Common Mistakes to Avoid

• Over-saucing: Too much sauce leads to soggy centers. Use a thin, even layer.
• Skipping the preheat: A hot stone or sheet is essential for a crisp underside.
• Rolling pin shaping: It crushes gas bubbles and flattens the rim. Use your hands.
• Wet cheese or pepperoni: Excess moisture prevents browning.Pat them dry if needed.
• Baking too low or too long: High heat gives rapid oven spring and that classic pizzeria finish.

Alternatives

• No stone or steel? Use an inverted heavy baking sheet that’s been preheated. It’s the next best thing.
• Rapid dough: If you’re short on time, let the dough rise at room temp until doubled (about 90 minutes), then shape and bake. Flavor won’t be as developed, but it still works.
• Cheese options: Substitute part-skim mozzarella if needed, or add a small handful of Monterey Jack for extra melt.
• Turkey pepperoni: Works fine—brush lightly with oil to help it crisp.
• Gluten-free route: Use a high-quality gluten-free pizza flour blend and follow package hydration guidance; par-bake the crust 5–7 minutes before saucing.

FAQ

How do I get those crispy, cupped pepperoni edges?

Pat the slices dry, use a brand known for cupping (often labeled “old world” or natural casing), and bake on high heat.

Slight overlap helps them curl and render nicely.

Can I use fresh mozzarella?

You can, but it’s higher in moisture and can make the pizza watery. If using it, slice and blot it well, and combine with low-moisture mozzarella for structure.

What if my dough keeps snapping back when I stretch it?

It needs more rest. Cover and let it relax for 10–15 minutes, then try again.

Cold dough resists stretching; give it time to warm slightly.

Is a pizza stone or steel really necessary?

Not strictly, but it makes a big difference. A preheated stone or steel stores heat and browns the bottom fast. An inverted preheated baking sheet is a solid backup.

How much sauce should I use per pizza?

Aim for 1/2 to 2/3 cup for a 14–16 inch pie.

You want coverage without puddles. Seeing a faint bit of dough through the sauce is perfect.

Why add a little sugar to the dough and sauce?

Sugar balances the acidity of the tomatoes and helps browning. It won’t make the pizza sweet; it just rounds out the flavor.

Can I make the dough ahead and freeze it?

Yes.

After the first rise and dividing into balls, oil and freeze them in bags. Thaw overnight in the fridge, then let sit at room temp 60–90 minutes before shaping.
