Step-by-Step: Chicken Florentine Panini

Step 1: Prepare the Chicken
Start by seasoning the chicken breasts with salt, pepper, and dried thyme. Heat 1 tablespoon of olive oil in a large skillet over medium heat. Once hot, add the chicken breasts and cook for about 6-7 minutes on each side or until the internal temperature reaches 165°F. Remove from the skillet and let them rest for a few minutes before slicing.
Step 2: Sauté the Onions
In the same skillet, add the remaining 1/2 tablespoon of olive oil. Add the sliced red onions and sprinkle with granulated sugar. Sauté for about 5-7 minutes, stirring occasionally, until the onions are caramelized and golden brown. Add the minced garlic and crushed red pepper flakes, cooking for an additional minute until fragrant. Stir in the balsamic vinegar and cook for another minute to combine. Remove from heat.
Step 3: Prepare the Spinach Mixture
In a mixing bowl, combine the thawed spinach with mayonnaise. Mix well until smooth and creamy. This will serve as a delicious spread on the panini.
Step 4: Assemble the Panini
Preheat your panini press or grill pan. Roll out the refrigerated pizza crust on a lightly floured surface to your desired thickness. Cut the dough into rectangular pieces that will fit your press or pan. Spread a generous layer of the spinach mixture on one side of each rectangle. Layer the sliced chicken on top, followed by the caramelized onions and provolone cheese. Top with another piece of dough, spinach side down.
Step 5: Cook the Panini
Place the assembled panini in the press or grill pan. If using a grill pan, you may need to use a heavy skillet on top to press down the sandwich. Cook for about 4-5 minutes, or until the crust is golden brown and the cheese has melted. Carefully flip halfway through if using a grill pan.
Step 6: Serve & Enjoy!
Once the panini is done, remove it from the heat and let it cool for a minute. Cut it in half and serve warm. Enjoy your Chicken Florentine Panini with a side of your favorite salad or chips for a complete meal!
Warm & Cool Weather Spins

This Chicken Florentine Panini is versatile enough to be enjoyed in any season. Here are some ideas on how to adapt it:
- Warm Weather: Serve it cold as a chicken salad panini by skipping the heating step and using cold chicken and fresh spinach.
- Cool Weather: Add roasted red peppers or sun-dried tomatoes for a heartier version.
- For a Grilled Version: Grill the chicken instead of sautéing for a smoky flavor.
- Add More Veggies: Incorporate roasted zucchini or bell peppers for added nutrition and taste.
Recipe Notes & Chef’s Commentary
This Chicken Florentine Panini is ideal for meal prep. You can easily cook the chicken and prepare the spinach mixture ahead of time, allowing for quick assembly on busy weeknights. Also, don’t hesitate to experiment with different cheeses or spreads based on what you have on hand. The key to a perfect panini is a good balance of flavors, so feel free to adjust to your taste!
Refrigerate, Freeze, Reheat
If you have leftovers (though they rarely last long!), you can store them in an airtight container in the refrigerator for up to three days. If you’d like to freeze them, wrap each panini tightly in plastic wrap and aluminum foil. They can be frozen for up to three months. To reheat, simply pop them in the oven or toaster oven until warmed through and crispy.
