Equipment Needed:

• Grill pan or panini press (a stovetop grill or electric sandwich press)

• Basting brush (optional)

Step-by-Step Instructions

Step 1: Preparing the Chicken Marinade

Marinating is essential for flavor and tenderness. Here’s how to prepare and marinate the chicken properly.

1. Clean and trim the chicken breasts.
   Use a sharp knife to remove any excess fat or sinew. You may also butterfly the breasts for quicker and more even grilling or pound them to an even thickness using a meat mallet or rolling pin.

2. Combine the marinade ingredients.
   In a medium bowl, whisk together the olive oil, lemon juice, minced garlic, Dijon mustard, oregano, smoked paprika, salt, pepper, and (if using) red pepper flakes. The lemon adds acidity, tenderizing the meat, while the spices add depth.

3. Marinate the chicken.
   Place the chicken breasts in a resealable plastic bag or a shallow dish. Pour the marinade over them, making sure each piece is well-coated. Seal or cover and refrigerate for at least 30 minutes—ideally 2 to 4 hours. Avoid marinating overnight, as the acid in the lemon can begin to break down the protein excessively, resulting in a mushy texture.

4. Bring to room temperature before grilling.
   Remove the chicken from the fridge about 15 minutes before cooking. This ensures even cooking and helps prevent the exterior from burning while the interior is still cold.

Step 2: Grilling the Chicken

1. Preheat your grill or grill pan.
   Heat your pan or grill press over medium-high heat for 5 minutes. If you’re using a stovetop grill, brush it lightly with olive oil to prevent sticking.

2. Grill the chicken breasts.
   Place the chicken on the hot grill. Cook for 5 to 7 minutes per side, depending on the thickness. Do not move the chicken around unnecessarily—this ensures nice grill marks and even cooking.

3. Check doneness.
   The chicken is done when the internal temperature reaches 165°F (74°C). Use a meat thermometer for accuracy. The juices should run clear, not pink.

4. Rest the chicken.
   Transfer the grilled chicken to a clean plate. Tent loosely with foil and let it rest for 5 to 10 minutes. This allows the juices to redistribute throughout the meat, ensuring moist, flavorful bites.

5. Slice the chicken.
   Once rested, slice the chicken breasts thinly against the grain for the most tender texture. Set aside.

Step 3: Preparing the Sandwich Ingredients

While the chicken is grilling or resting, prepare the other components of your panini.

1. Slice the bread.
   Cut your ciabatta or focaccia horizontally if not already sliced. If using sourdough or baguette, slice into even sections that match your chicken cuts.

2. Prep the veggies.

   • Slice the tomato into thin rounds.

   • Peel and slice the red onion into thin rings.

   • Wash and dry the spinach or arugula.
     These ingredients will provide freshness, crunch, and a contrast to the warm, melty center of the panini.

3. Optional spreads.

   • Mix mayonnaise with a touch of garlic or herbs if you prefer a creamy base.

   • Use pesto for a rich, herby note.

   • Other spread ideas: sun-dried tomato spread, aioli, chipotle mayo, or honey mustard.

Step 4: Assembling the Panini

Now comes the fun part—layering your sandwich for maximum flavor and balance.

1. Lay out the bread slices.
   On the inside of each bottom slice, spread a thin layer of mayonnaise or pesto. This acts as a moisture barrier and adds richness.

2. Add the sliced grilled chicken.
   Place a generous portion of sliced chicken on the bottom slice. Try not to overload it, or the sandwich may fall apart during grilling.

3. Layer the cheese.
   Place one or two slices of provolone (or your chosen cheese) on top of the chicken. If you’re a cheese lover, feel free to double up.

4. Add vegetables.

   • Top with a few tomato slices.

   • Add a few onion rings (red onion gives a mild bite).

   • Place a handful of spinach or arugula for color and freshness.

5. Close the sandwich.
   Place the top half of the bread on the sandwich and press down gently.

Step 5: Grilling the Panini

You have two main options: using a panini press or a grill pan with a weight. Both methods can produce excellent results.

Using a Panini Press:

1. Preheat the press according to the manufacturer’s instructions (usually medium-high).

2. Brush the outside of the bread lightly with olive oil or softened butter. This creates that golden, crispy crust.

3. Place the sandwich in the press and lower the lid.

4. Grill for 4 to 6 minutes, or until the bread is crisp and golden, and the cheese is fully melted.

5. Remove and let rest for a minute before slicing.

Using a Grill Pan or Skillet:

1. Preheat the pan over medium heat.

2. Add a bit of butter or oil to the surface if your pan isn’t non-stick.

3. Place the sandwich in the pan, and then place a heavy skillet, a foil-wrapped brick, or another weighted object on top.

4. Cook for 3 to 5 minutes per side, checking frequently to prevent burning.

5. Flip and repeat, pressing gently with the weight to ensure even contact.

Step 6: Serving the Grilled Chicken Panini

Once the sandwich is grilled to perfection:

1. Let it rest for a minute so the cheese doesn’t ooze out when you cut it.

2. Slice diagonally or straight across, depending on your presentation style.

3. Serve hot, optionally with a side of:

   • Mixed greens or Caesar salad

   • Sweet potato fries or kettle chips

   • Pickles or olives

   • A small cup of tomato soup for dipping
