Here’s everything that goes into this creamy, tangy appetizer and why each ingredient earns its place.

For the Stuffed Pepperoncini

• 20–24 whole pepperoncini peppers, drained — These mild, tangy peppers form the base of the recipe and provide the perfect vessel for the rich, creamy filling.
• 8 oz cream cheese, softened — The rich, smooth base of the filling that creates that classic creamy texture.
• ½ cup grated Parmesan cheese — Adds a salty, nutty, umami-rich depth to the filling.
• 1 cup shredded mozzarella cheese — Contributes a mild, stretchy quality that rounds out the texture of the filling.
• 2 cloves garlic, minced — Infuses the filling with bold, aromatic garlic flavor.
• 2 tbsp chopped fresh parsley — Adds fresh, herbal brightness to the rich cheese mixture.
• 1 tbsp chopped fresh chives — Contributes a mild, oniony bite that complements the garlic beautifully.
• 1 tsp Italian seasoning — A classic herb blend that ties the filling together.
• ½ tsp garlic powder — Reinforces the garlic flavor alongside the fresh minced cloves.
• ¼ tsp onion powder — Adds subtle savory depth to the filling.
• ¼ tsp freshly ground black pepper — Adds a subtle, warm bite.

For the Italian Marinade

• ⅓ cup extra virgin olive oil — Forms the rich, flavorful base of the marinade.
• 2 tbsp pepperoncini brine — This key ingredient intensifies the tangy pepperoncini flavor throughout the marinade.
• 2 tbsp red wine vinegar — Adds the essential tangy backbone to the marinade.
• 1 tbsp fresh lemon juice — Contributes bright acidity that balances the richness of the cream cheese filling.
• 2 cloves garlic, thinly sliced — Infuses the marinade with even more aromatic garlic flavor.
• 1 tsp dried oregano — Adds classic Italian herb flavor to the marinade.
• ½ tsp crushed red pepper flakes (optional) — For those who enjoy a subtle kick of heat.
• ½ tsp kosher salt — Enhances all the other flavors in the marinade.
• ¼ tsp freshly ground black pepper — Adds a subtle peppery finish.
