How to Make Chicken Florentine Panini

Making a Chicken Florentine Panini is as enjoyable as eating it! You’ll love the process of layering these flavors and then grilling the sandwich until it’s perfectly crispy. Let’s dive into the steps!
Start by preparing the mayonnaise spread. In a small bowl, stir together mayonnaise and garlic. Cover and refrigerate this mixture until you’re ready to use it, allowing the flavors to meld together beautifully.
Preheat your oven to 375 degrees. While the oven heats, grab a large nonstick skillet. Add 1 tablespoon of olive oil and place it over medium heat. Once hot, add the red onion. Sauté for about 3 minutes until the onions become translucent and fragrant.
Now, sprinkle in granulated sugar, balsamic vinegar, and crushed red pepper flakes. Continue to sauté the mixture for another 5 minutes, letting the onions caramelize slightly. Once they’re done, remove the skillet from heat and set the onions aside.
When your oven is preheated, take the tube of refrigerated pizza crust and unroll it onto a jellyroll pan, pressing it into a 15×10-inch rectangle. Bake for 10 minutes until lightly golden. Once baked, let it cool for a few minutes, then cut it into 4 rectangles.
After the onions are cooked, transfer them to a bowl. In the same skillet, wipe it clean and prepare to cook the chicken breasts. Using a meat mallet or a rolling pin, flatten the chicken to about 1/4-inch thickness. Season both sides with salt, pepper, and dried thyme.
Heat the remaining 1/2 tablespoon of olive oil in the skillet over medium-high heat. Add the seasoned chicken breasts and cook for 4 to 5 minutes on each side or until they’re cooked through and reach an internal temperature of 165 degrees. Once cooked, remove them from the skillet and let them rest for about 5 minutes before slicing.
To assemble your panini, take 2 of the pizza rectangles and spread the mayonnaise mixture on one side of each. On the other 2 rectangles, layer the sliced chicken, thawed spinach, and sautéed onions. Top everything off with provolone cheese slices. Place the remaining rectangles on top, mayonnaise side down, creating sandwiches.
Next, lightly grease your cast iron skillet with olive oil and heat it over medium-high heat. Carefully place the sandwiches in the skillet. Cook until the bottoms are golden brown, pressing down on them with a spatula to ensure even cooking.
Once the first side is golden, flip the sandwiches and cook until they are equally golden on the other side. This should take another few minutes.
Finally, cut each sandwich in half, and serve hot. Enjoy your delicious homemade Chicken Florentine Panini!
Things Worth Knowing
- Cooking chicken: Ensure the chicken is cooked to an internal temperature of 165 degrees for safety.
- Thickness matters: Flattening the chicken breasts helps them cook evenly and quickly.
- Don’t rush the onions: Allowing the onions to caramelize fully enhances their natural sweetness.
- Grilling technique: Pressing the sandwiches down while cooking ensures a crispy texture.
Tips for Success

To ensure your Chicken Florentine Panini turns out perfectly every time, here are some helpful tips:
- Storage: Store any leftover sandwiches in an airtight container in the fridge. They can last up to 3 days.
- Freezing: You can freeze assembled but uncooked sandwiches. Just wrap them tightly in plastic wrap and foil.
- Pairing: Serve with a fresh salad or a bowl of soup for a complete meal.
- Variations: Add roasted red peppers or avocado for an extra kick of flavor.
- Grilling alternatives: If you don’t have a cast iron skillet, use a panini press for an even easier cooking method!
