Preheat your oven to 375º F. This ensures that the chicken cooks evenly and at the right temperature, sealing in the juices and flavors.
Spray a 9×13-inch baking dish with nonstick cooking spray. This step is crucial to prevent the chicken from sticking and makes for easy cleanup later.
Season the chicken tenderloins with the garlic and herb seasoning. Make sure to coat them well, so each piece is flavorful. This is where the magic starts!
In a large skillet over medium-high heat, heat the olive oil. Once hot, add the seasoned chicken and cook for around 2 minutes per side until golden brown. You want a nice sear on the outside to lock in those juices.
After browning, transfer the chicken to the prepared baking dish. This forms the base layer of your delicious meal.
In a small bowl, stir together the sour cream and grated parmesan cheese. This mixture will be spread over the chicken, creating that creamy layer we all love.
Season the sour cream mixture with salt and black pepper to taste. Taste is key here! It should be flavorful but not overwhelming.
Spread the sour cream mixture evenly over the chicken in the baking dish. Make sure every piece is coated for maximum flavor.
Next, sprinkle the crushed croutons evenly over the chicken. This will add a delightful crunch that contrasts with the creaminess.
Finally, dot the top with cubed butter. As it bakes, the butter will melt and flavor the entire dish.
Bake in your preheated oven for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165º F. Keep an eye on it; you want it perfectly cooked, juicy, and full of flavor.
Once baked, remove from the oven and garnish with parsley if desired. This adds a beautiful touch and a fresh flavor!
