Recipe Overview

Prep time: 15 minutes
Cook time: 10-12 minutes
Servings: 4 paninis

Difficulty level: Easy

Equipment needed:

A panini press or grill pan. If you don’t have a panini press, a heavy skillet and a foil-wrapped brick or another heavy pot can act as a substitute.

Make-ahead options:

The pesto can be made up to 3 days in advance and stored in an airtight container in the refrigerator. The grilled chicken can be cooked and sliced 1 day ahead. Assemble the paninis just before cooking for the best texture.

Ingredients

Main Ingredients

• 8 slices sourdough bread – about 1/2 inch thick, sturdy enough to hold fillings
• 8 ounces fresh mozzarella cheese – sliced into 1/4 inch thick rounds, or shredded
• 1 cup cooked chicken breast – thinly sliced or shredded, perfectly seasoned
• 1/2 cup sun-dried tomatoes – packed in oil, drained and roughly chopped for bursts of intense flavor

For the Basil Pesto

• 2 cups fresh basil leaves – packed, vibrant green for the best aroma
• 1/2 cup pine nuts – lightly toasted for depth, or use walnuts for a richer flavor
• 1/2 cup grated Parmesan-style cheese – adds a salty, umami punch
• 3 cloves garlic – peeled, for a pungent kick
• 1/2 cup extra virgin olive oil – high quality, to emulsify and add fruitiness
• 1/4 teaspoon salt – or to taste
• Pinch black pepper – freshly ground

Pro Tips

1. Toasting the Pine Nuts: Don’t skip this step! Lightly toasting the pine nuts in a dry skillet over medium-low heat for 2-3 minutes until fragrant brings out their nutty flavor. It adds an incredible depth to your pesto. Watch them closely, they can burn quickly.
2. Room Temperature Cheese: Allow your mozzarella to come to room temperature for about 15 minutes before assembling. This helps it melt more evenly and quickly, preventing a cold center in your panini.
3. Don’t Overfill: It’s tempting to load up a panini, but overfilling can cause ingredients to spill out and the bread to become soggy. Aim for a balanced layer of fillings so the panini can press evenly and cook thoroughly. A perfectly filled panini is a joy.
4. Butter the Outside: While some recipes call for brushing the inside, buttering the outside of the bread before pressing ensures a beautifully golden-brown, crispy crust. It’s that rich, inviting crunch you want.

Instructions

Step 1: Prepare the Pesto

Start by making your vibrant basil pesto. In a food processor, combine the fresh basil leaves, toasted pine nuts, grated Parmesan-style cheese, and garlic cloves. Pulse several times until the mixture is finely chopped. With the food processor running, slowly drizzle in the extra virgin olive oil until the pesto is smooth and well combined. Season with salt and black pepper to taste. This aromatic sauce is the heart of your panini.

Step 2: Prepare the Chicken and Sun-Dried Tomatoes

If your chicken isn’t already cooked, grill or pan-fry a chicken breast until fully cooked and juicy. Let it rest for a few minutes, then thinly slice or shred it. Drain the sun-dried tomatoes from their oil and roughly chop them. These steps can be done ahead of time, saving you precious minutes.

Step 3: Assemble the Paninis

Lay out your sourdough bread slices on a clean surface. Spread a generous layer of the homemade pesto on one side of each of the 8 slices. On 4 of the slices, layer the sliced mozzarella cheese, followed by the thinly sliced chicken, and then the chopped sun-dried tomatoes. Top with another layer of mozzarella cheese. Place the remaining 4 slices of pesto-spread bread on top, pesto-side down, to complete your sandwiches.

Step 4: Grill the Paninis

Lightly butter the outside of each assembled panini. Preheat your panini press to medium-high heat. If using a grill pan, heat it over medium heat and add a touch of butter or oil. Place the buttered paninis onto the hot press or pan. Close the panini press or place a heavy, foil-wrapped brick on top of the sandwiches in the grill pan. Cook for 4-6 minutes, or until the bread is golden brown and crispy, and the cheese is beautifully melted and gooey. The exact time will depend on your press or pan.

Step 5: Serve Immediately

Carefully remove the hot paninis from the press or pan. Allow them to rest for 1-2 minutes before slicing diagonally. This brief rest helps the cheese set slightly and prevents all the delicious fillings from oozing out immediately. Serve warm and enjoy the delightful flavors!

Variations & Customization

Dietary Modifications

• Gluten-Free: Simply swap the sourdough bread for your favorite gluten-free bread that is robust enough to hold up to pressing. Ensure the bread is thick enough to prevent crumbling.
• Dairy-Free/Vegan: Use a high-quality dairy-free mozzarella alternative that melts well. For the pesto, substitute the Parmesan-style cheese with nutritional yeast for a cheesy flavor, or a dairy-free Parmesan alternative. Ensure your bread is also dairy-free.

Flavor Variations

• Spicy Version: Add a pinch of red pepper flakes to your pesto for a subtle heat. You could also thinly slice some jalapeño or serrano peppers and add them to the filling for a bolder kick.
• Seasonal Twists:
• Autumn Harvest: Incorporate thinly sliced roasted butternut squash and a sprinkle of fresh sage leaves with the chicken.
• Mediterranean Flair: Add sliced Kalamata olives and crumbled plant-based feta-style cheese to the filling for a briny, tangy note.
• Smoky Twist: Use turkey bacon or beef bacon strips, cooked until crispy, in place of or in addition to the chicken.

Serving & Storage

Serving Suggestions

Serve these golden paninis immediately, while the cheese is still wonderfully melted and the bread is crisp. For a beautiful presentation, slice them diagonally, showing off those delicious layers. They pair beautifully with a simple side salad dressed with a light vinaigrette, a warm bowl of tomato soup, or some crispy sweet potato fries.

For beverages, consider a refreshing glass of sparkling apple cider, a vibrant berry mocktail, or a soothing cup of iced hibiscus tea. These non-alcoholic options complement the rich flavors of the panini without overwhelming them.

Storage Instructions

• Refrigerator: Leftover cooked paninis can be stored in an airtight container in the refrigerator for up to 2 days. The bread will soften, but the flavors will still be good.
• Freezer: Freezing assembled but uncooked paninis is not recommended, as the bread and fresh mozzarella may become soggy upon thawing. Cooked paninis can be frozen, wrapped tightly in foil and then placed in a freezer-safe bag, for up to 1 month.
• Reheating: To reheat refrigerated paninis, the best method is to use a panini press or a dry skillet over medium heat until they are warmed through and crispy again, about 5-7 minutes. If reheating from frozen, thaw in the refrigerator overnight, then reheat as described. Avoid the microwave, as it will make the panini soggy.

Frequently Asked Questions

1. Can I use store-bought pesto for this recipe?

Absolutely! While homemade pesto offers unparalleled freshness and flavor, a good quality store-bought pesto is a convenient alternative. Just be sure to check the ingredients list to ensure it meets your dietary preferences and quality standards. Look for one made with extra virgin olive oil and fresh basil for the best results. You might want to add a tiny squeeze of fresh lemon juice to brighten up store-bought versions.

2. What kind of bread works best for paninis?

Sourdough is fantastic for paninis because its crust gets wonderfully crispy and its chewy interior holds up well to pressing. Other excellent choices include ciabatta, focaccia, or a good country-style white bread. The key is to choose a bread that is sturdy, not too thin, and has a good crumb structure that won’t compress into a flat, dense disc. Avoid very soft or airy breads.

3. How can I prevent my panini from getting soggy?

The primary culprits for soggy paninis are too much moisture in the filling or overfilling. Ensure your sun-dried tomatoes are well-drained. If using fresh tomatoes, remove the seeds and excess liquid. Also, buttering the outside of the bread creates a barrier against moisture and helps achieve that desirable crispy crust. Don’t press the panini for too long, as this can also lead to a dense, soggy texture.

4. Can I make this panini vegetarian?

Yes, easily! Simply omit the chicken. You can replace it with additional sun-dried tomatoes, roasted red peppers, grilled zucchini, or even some thinly sliced grilled portobello mushrooms for a hearty, flavorful vegetarian option. A layer of fresh spinach or arugula added after cooking can also provide a nice peppery contrast.

5. What’s the best way to clean a panini press?

Always allow your panini press to cool completely before cleaning. Once cool, use a damp cloth or paper towel to wipe down the non-stick plates. For stubborn stuck-on bits, dampen a paper towel with a little cooking oil and gently rub. Avoid abrasive scrubbers or harsh detergents, as these can damage the non-stick coating. Some presses have removable plates that can be washed in the sink or dishwasher.

Final Thoughts

There’s something incredibly satisfying about crafting a meal that brings so much joy with such simple steps. This pesto panini recipe is a testament to that. It’s warm, comforting, and packed with layers of delightful flavor and texture.
