Tender chicken breast and Yukon Gold potatoes cooked in a rich creamy garlic sauce with melted cheddar and mozzarella cheese. A complete one-pan meal with over 42 grams of protein per serving, perfect for busy weeknight dinners.
Heat olive oil in a large 12-inch oven-safe skillet or Dutch oven over medium-high heat until shimmering. Add chicken pieces and season with salt, pepper, paprika, garlic powder, and onion powder. Cook for 5 to 6 minutes until golden brown on the outside. Remove to a plate and set aside – chicken will finish cooking in the oven.
In the same skillet, add diced onion and cook for 3 to 4 minutes until softened. Add minced garlic and cook for 1 minute, stirring constantly, until fragrant.
Add cubed potatoes and stir to coat in the garlicky oil. Let sit undisturbed for 30 seconds to pick up light color.
Pour in chicken broth and bring to a simmer. Reduce heat to medium-low, cover, and cook for 10 to 12 minutes until potatoes are slightly tender but still hold slight resistance when pierced with a fork.
Stir in heavy cream and return the browned chicken to the skillet. Stir gently to combine. Taste and adjust salt and pepper. If sauce is too thick, add a splash of broth. If too thin, simmer uncovered 2 to 3 minutes.
Sprinkle shredded cheddar and mozzarella evenly over the top without stirring.
Transfer skillet to preheated oven and bake for 15 to 20 minutes until cheese is fully melted, bubbly, and golden at the edges. For a crispier top, broil for the final 2 minutes – watch carefully.
Remove from oven, rest 5 minutes, garnish with fresh parsley, and serve hot directly from the skillet.
Notes
Use Yukon Gold potatoes for best texture – they hold their shape better than Russets in this creamy sauce.
Always shred cheese fresh from a block. Pre-shredded cheese contains anti-caking agents that prevent smooth melting.
A 12-inch skillet minimum is required – this recipe produces generous volume and will overcrowd a smaller pan.
For extra protein, stir in cooked crumbled bacon before adding the cheese topping.
This dish tastes even better the next day after flavors meld overnight in the refrigerator.
