These Giardiniera Chicken Melts take simple grilled chicken to a new level—saucy, cheesy, and tangy with a satisfying crunch from the giardiniera. They’re an easy, flavor-forward weeknight dinner that also shines at weekend gatherings.
Giardiniera is a classically Italian relish of pickled vegetables preserved in oil or vinegar. It comes mild or hot—if you like heat, use the hot variety for a bold, peppery kick. The pickled vegetables add a bright, acidic counterpoint to the rich marinara and melted mozzarella, giving each bite balance and complexity.
This recipe is straightforward: make a simple herb-and-lemon marinade, pound and marinate butterflied chicken breasts, and grill the chicken alongside zucchini and mini peppers. Near the end of grilling, top each chicken breast with marinara, shredded mozzarella, and giardiniera, then cover briefly until the cheese melts. Serve immediately with the grilled vegetables for a colorful, satisfying plate.
Ingredients:
- 6 garlic cloves, minced
- 2 tablespoons minced fresh oregano
- ¼ cup minced fresh parsley
- 1/3 cup extra virgin olive oil (for the marinade)
- 2 teaspoons kosher salt
- 1 teaspoon freshly ground black pepper
- Zest of ½ lemon
- 2 tablespoons freshly squeezed lemon juice
- 2 tablespoons red wine vinegar
- 4 boneless, skinless chicken breasts, butterflied
- 1 pound mini bell peppers
- 2 medium zucchini, sliced ¼-inch thick on the diagonal
- 3 tablespoons extra virgin olive oil (for the veggies)
- 1 cup marinara sauce
- ½ cup shredded mozzarella cheese
- ¾ cup mild or hot giardiniera, drained slightly
- Fresh parsley for garnish
Recipe Step-by-Step:
Step One: Make the Chicken Marinade
In a large bowl, whisk together the minced garlic, minced oregano, minced parsley, 1/3 cup extra virgin olive oil, kosher salt, freshly ground black pepper, lemon zest, lemon juice, and red wine vinegar until combined. This bright, herb-forward mixture will both flavor and tenderize the chicken.
Step Two: Prep the Chicken
Place each chicken breast on a cutting board and butterfly by slicing lengthwise almost through, then open like a book. Cover the chicken with plastic wrap and, using a meat mallet or rolling pin, pound to an even ¼-inch thickness. Transfer the butterflied breasts into the bowl with the marinade and toss to coat. Let rest at room temperature for at least 30 minutes, or refrigerate for up to 4 hours for deeper flavor.
Step Three: Prep the Veggies
On a large sheet pan, arrange the mini bell peppers and the sliced zucchini in a single layer. Drizzle with 3 tablespoons extra virgin olive oil and season lightly with salt and pepper. Keep the vegetables ready to move directly to the grill so they cook while the chicken is grilling.
Step Four: Prep the Grill
Preheat your grill to medium-high, about 350–400°F. Oil the grates to prevent sticking: dip a scrunched paper towel in a small amount of neutral oil (such as avocado oil) and, using tongs, wipe the grates carefully. Use only a little oil to avoid flare-ups.
Step Five: Start the Chicken
Place the marinated chicken on one half of the grill and close the lid. Cook about 4 minutes per side until the chicken is golden and marked by the grill. Keep the lid closed to maintain even heat.
Step Six: Grill the Veggies
While the chicken cooks, place the prepared mini peppers and zucchini on the other half of the grill in a single layer. Grill for about 6 minutes total, turning once halfway through, until the zucchini is tender and both vegetables show good char. Transfer the veggies to a platter and keep warm.
Step Seven: Finish the Chicken
Lower the grill temperature to medium-low. Spoon about 1/4 cup of marinara onto each chicken breast (or divide 1 cup total among the four pieces), sprinkle evenly with shredded mozzarella (about ½ cup total), and top with a generous layer of giardiniera (about ¾ cup divided). Close the lid and cook 3–4 minutes more, until the cheese is melted and bubbly and the giardiniera is warmed through.
Step Eight: Serve and Enjoy!
Transfer the finished chicken to a serving platter and garnish with chopped fresh parsley. Plate with the grilled zucchini and mini peppers alongside. These melts are best served hot so the cheese remains gooey and the giardiniera keeps its bright, pickled bite.
Tips, Variations, and Storage
- Giardiniera heat level: choose mild if you prefer subtle tang, or hot for a spicier finish. You can always start with mild and add a few hot pepper pieces to taste.
- Substitutions: provolone or fontina can be used instead of mozzarella for a different melting profile and flavor.
- Make-ahead: marinate the chicken up to 4 hours ahead to save time. Keep vegetables prepped in the fridge until ready to grill.
- Storage: refrigerate leftovers in an airtight container for up to 3–4 days. Reheat gently in a low oven or in a skillet over medium heat so the chicken stays moist and the cheese reheats evenly.
- Serving ideas: these chicken melts pair well with a simple green salad, crusty bread, or a bed of mixed grains to soak up extra juices and marinara.
