Cooking Chicken Florentine Panini: The Process

Step 1: Prepare the Garlic Mayonnaise
In a small bowl, combine the mayonnaise and minced garlic. Mix until well combined, then set aside. This will be the creamy spread that ties all the flavors together.
Step 2: Cook the Onions
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Once hot, add the sliced red onion and sprinkle with granulated sugar. Cook, stirring occasionally, until the onions are soft and caramelized, about 8-10 minutes. Add in the balsamic vinegar and crushed red pepper flakes, stirring to combine. Remove from heat and set aside.
Step 3: Cook the Chicken
In the same skillet, add the remaining 1/2 tablespoon of olive oil. Season the chicken breasts with salt, pepper, and dried thyme. Once the oil is hot, add the chicken to the skillet. Cook for about 6-7 minutes on each side, or until the chicken is cooked through and has a nice golden color. Remove from the skillet and let it rest for a few minutes before slicing.
Step 4: Prepare the Spinach
While the chicken is resting, take the thawed spinach and squeeze out as much liquid as possible. This helps prevent the panini from becoming soggy.
Step 5: 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 it into rectangles that will fit your press or pan. On one half of the dough, spread a generous layer of the garlic mayonnaise. Layer on the sliced chicken, caramelized onions, spinach, and a few slices of provolone cheese. Top with the other half of the dough and seal the edges gently.
Step 6: Grill the Panini
Place the panini in the preheated panini press or grill pan. Cook until the crust is golden brown and the cheese has melted, about 3-5 minutes. If using a grill pan, you may want to use a heavy skillet on top to press down the panini for an even cook.
Step 7: Serve and Enjoy
Once cooked, remove the panini from the heat and let it rest for a moment before slicing. This allows the cheese to set slightly, making it easier to handle. Serve warm with your favorite side, like a crisp salad or some potato chips.
Make It Fit Your Plan

- Vegetarian Option: Replace chicken with grilled portobello mushrooms or additional spinach and cheese.
- Low-Carb Version: Use lettuce wraps instead of pizza crust for a lighter option.
- Spicy Kick: Add jalapeƱos or pepper jack cheese for an extra heat boost.
- Meal Prep: Prepare the ingredients ahead of time and assemble right before grilling for a quick meal.
Pro Perspective
This Chicken Florentine Panini is a versatile recipe that can easily be personalized. Donāt hesitate to experiment with different cheeses, such as mozzarella or cheddar, depending on your preference. The key to a great panini is ensuring the filling is well-seasoned and balanced. Also, remember that pressing the panini down while cooking aids in the melty cheese factor, which is crucial for that satisfying bite we all crave.
Prep Ahead & Store
If you want to make this Chicken Florentine Panini ahead of time, you can prepare the chicken and caramelized onions in advance and store them in the refrigerator for up to 3 days. When youāre ready to eat, simply assemble the panini and grill. If you have leftovers, they can be stored in an airtight container in the fridge.
