Directions
Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch glass casserole dish with a little olive oil or nonstick spray.
Pat the chicken breasts dry with paper towels. Place them in a single layer in the glass casserole dish. Sprinkle 1/2 teaspoon of the salt and 1/4 teaspoon of the black pepper evenly over both sides of the chicken.
In a medium mixing bowl or large measuring cup, whisk together the heavy cream, chopped sun-dried tomatoes, grated Parmesan, Italian seasoning, minced garlic, olive oil, remaining 1/2 teaspoon salt, remaining 1/4 teaspoon black pepper, and crushed red pepper flakes if using. The mixture will be thick and creamy with little bits of tomato and cheese throughout.
Hold the bowl over the glass casserole dish and slowly pour this one creamy mixture all over the raw chicken breasts, making sure each piece is well coated and there’s sauce pooling around them. Use a spatula to scrape out any remaining sauce and spread it evenly.
Cover the dish loosely with foil and bake for 15 minutes. Remove the foil and continue baking for another 15–20 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C). The sauce should be bubbling and slightly thickened around the edges.
