Equipment

  • Large oven-safe skillet (12-inch)
  • Oven
  • Cutting board
  • Chef's knife
  • Small bowl
  • Measuring cups and spoons
  • Whisk
  • Tongs
  • Meat thermometer
  • Cheese grater

Ingredients
  

  • 4 medium boneless, skinless chicken breasts about 1.5 lbs total
  • 1 teaspoon salt
  • 1 teaspoon garlic powder
  • 1 teaspoon paprika
  • ½ teaspoon black pepper
  • 1 tablespoon olive oil
  • 2 tablespoons unsalted butter, divided
  • 1 medium yellow onion, diced
  • 8 ounces cremini mushrooms, sliced
  • 3 cloves garlic, minced
  • 2 tablespoons all-purpose flour
  • 1 cup chicken broth
  • 1 cup full-fat sour cream
  • 2 cups shredded cheese blend Monterey Jack and cheddar
  • 2 tablespoons fresh parsley, chopped, for garnish

Instructions
 

  • Preheat your oven to 400°F (200°C). Pat the chicken breasts completely dry with paper towels. In a small bowl, mix together the salt, garlic powder, paprika, and black pepper. Season the chicken generously on all sides.
  • Heat the olive oil and 1 tablespoon of butter in a large, oven-safe skillet over medium-high heat. Once sizzling, place the chicken in the skillet and sear for 4-5 minutes per side, until a deep golden-brown crust forms. The chicken will not be fully cooked. Remove it from the skillet and set aside on a plate.
  • Reduce the heat to medium and add the remaining tablespoon of butter to the skillet. Add the diced onion and sliced mushrooms. Sauté for 6-8 minutes, until the onions are soft and the mushrooms have browned. Add the minced garlic and cook for one more minute until fragrant.
  • Sprinkle the all-purpose flour over the vegetables and stir constantly for one minute to cook off the raw taste. Slowly pour in the chicken broth while whisking continuously to prevent lumps. Bring the sauce to a simmer and let it cook for 2-3 minutes to thicken.
  • Remove the skillet from the heat. Let it cool for a moment, then stir in the full-fat sour cream until the sauce is smooth and creamy. Taste and adjust seasoning if needed. Nestle the seared chicken breasts back into the sauce.
  • Top each chicken breast generously with the shredded cheese blend. Transfer the entire skillet to the preheated oven.
  • Bake for 15-20 minutes, or until the chicken is cooked through (internal temperature reaches 165°F or 74°C) and the cheese is melted, bubbly, and golden brown. Let the dish rest for 5 minutes before garnishing with fresh parsley and serving.

Notes

For best results, use full-fat sour cream and shred your own cheese from a block to avoid grainy sauces. To prevent the sour cream from curdling, always remove the skillet from the heat before stirring it in. For variations, try adding crumbled bacon, a teaspoon of fresh thyme, or a pinch of red pepper flakes for some heat. This dish is excellent served over mashed potatoes, egg noodles, or rice with a side of roasted asparagus or steamed green beans.
