Scrub the potatoes and prick them all over with a fork. Microwave on high (800–900W) for 6–8 minutes, turning halfway, until partially tender.
Brush with olive oil and season with salt and pepper. Place the potatoes in a baking dish. Bake at 400°F (200°C) for 20–25 minutes, until a knife slides in easily and the skins are crisp. Leave the oven on.
Cook the Chicken
Season the chicken breast with the salt, smoked paprika, cayenne, Italian seasoning, and garlic powder.
Heat the oil in a pan over medium heat. Sear the chicken for 5–7 minutes per side, until golden and cooked through (165°F / 74°C). Rest for 5 minutes, then cut into small cubes.
Make the Alfredo Sauce
Melt the butter in a saucepan over medium heat. Add the garlic and cook for 30 seconds, then stir in the flour and cook for 1 minute.
Slowly whisk in the cream until smooth. Add the salt, pepper, chicken bouillon powder, Italian seasoning, and red pepper flakes.
Simmer for 2–3 minutes, stirring often, until slightly thickened. Stir in the Parmesan until melted and smooth. If the sauce gets too thick, loosen it with a splash of milk.
Assemble and Bake
Cut a deep cross into each potato and squeeze the ends to open it up. Fluff the insides with a fork, then mix in the butter, mozzarella, and a pinch of salt and pepper.
Top with the chicken, spoon the Alfredo sauce over, and sprinkle with the mozzarella and Parmesan.
Bake at 400°F (200°C) for 10–15 minutes, until the cheese is golden and the sauce is bubbling. Garnish with chives or parsley and serve.

Notes
Air fryer shortcut: After microwaving, air fry the oiled and seasoned potatoes at 400°F (200°C) for 12–18 minutes, turning halfway, until tender and crisp.
No microwave: Bake the potatoes at 400°F (200°C) for 50–60 minutes, until tender.
