Preheat your oven to 375°F (190°C).
Season the chicken breasts with salt, pepper, and any additional seasonings you prefer.
In a large skillet, heat olive oil over medium-high heat. Add the seasoned chicken breasts and cook for about 5-6 minutes on each side until browned and cooked through. Remove from skillet and set aside.
In the same skillet, add the minced garlic and cook for about 1 minute until fragrant.
Add the broccoli florets to the skillet and sauté for 3-4 minutes until slightly tender.
Return the cooked chicken breasts to the skillet, placing them on top of the broccoli.
Sprinkle the shredded pepper jack cheese evenly over the chicken and broccoli.
Transfer the skillet to the preheated oven and bake for about 10-15 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let it cool slightly before serving.
Enjoy!
