Preheat your [oven] to $400^circtext{F}$. Pat the [chicken breasts] dry, this is important for browning! Then, little Olivia takes over seasoning both sides with [salt], [black pepper], [paprika], [garlic powder], and [Italian seasoning].
Cut your [baby potatoes] in half and let's get them coated! Toss them in a bowl with $1$ [tablespoon] of [olive oil], [salt], and [pepper]. We use a large bowl here so nothing escapes.
Heat the remaining [olive oil] in your [oven-safe skillet] over medium-high heat. When it shimmers, add the [chicken breasts] and cook for 4-5 minutes per side until they're golden brown. Remove the [chicken] and set it aside on a plate.
Add the halved [potatoes] to the same skillet, cut-side down. Let them cook for 5-6 minutes until they start getting those beautiful, crispy golden edges. This little step is what makes them taste better than fries!
While the [potatoes] are browning, melt the [unsalted butter] in a [small saucepan] over medium heat. Add the minced [garlic] and cook for just 1 minute, we don't want it to burn! Then, pour in the [heavy cream], [grated Parmesan cheese], [Italian seasoning], [salt], and [pepper]. Stir until it’s smooth and slightly thickened, about 3-4 minutes.
Return the seared [chicken breasts] to the skillet among the [potatoes]. Pour that gorgeous, creamy [Garlic Parmesan Sauce] right over everything. Our favorite part? Sprinkle the entire top with [shredded mozzarella cheese]!
Carefully transfer the whole [skillet] to the preheated [oven] and bake for 15 to 18 minutes. The [chicken] is done when it hits $165^circtext{F}$ and the [cheese] is melted and bubbly. Garnish with fresh [parsley] before serving!
