Ingredients

Scale

Main Protein:

  • 4 boneless, skinless chicken breasts (about 1.5 lbs / 680 grams)

Vegetables and Base:

  • 4 cups fresh spinach
  • 1 medium yellow onion, diced
  • 3 cloves garlic, minced

Dairy and Seasonings:

  • 1 cup heavy cream (240 milliliters)
  • 1 cup grated Parmesan cheese
  • 1 cup low-sodium chicken broth (240 milliliters)
  • 2 cups short pasta (such as penne)
  • 2 tablespoons olive oil
  • Salt and pepper to taste

Instructions

  1. Preheat your oven to 375°F (190°C). Spray a 9×13-inch baking dish with nonstick cooking spray to prevent sticking.
  2. Sprinkle 1 teaspoon salt and ½ teaspoon black pepper evenly over 4 chicken breasts, ensuring complete seasoning coverage.
  3. Heat 2 tablespoons olive oil in a large skillet over medium heat. Sauté 1 diced onion until soft and translucent, approximately 4-5 minutes.
  4. Add 3 minced garlic cloves to the skillet. Cook for 45-60 seconds until fragrant, stirring constantly to prevent burning.
  5. Toss 4 cups fresh spinach into the skillet. Stir until spinach wilts completely, about 2-3 minutes.
  6. Pour 1 cup heavy cream, 1 cup chicken broth, and 1 cup grated Parmesan into the skillet. Whisk until sauce becomes smooth and slightly thickened.
  7. Arrange seasoned chicken breasts in the prepared baking dish. Pour cream mixture evenly over the chicken, coating each piece.
  8. Optional: Scatter 2 cups cooked penne pasta around the chicken if desired for additional texture.
  9. Cover the dish tightly with aluminum foil. Bake at 375°F for 30 minutes to ensure chicken cooks through.
  10. Remove foil and continue baking 15-20 minutes until sauce bubbles and chicken turns golden brown.
  11. Remove from oven and let casserole rest 10 minutes before serving, allowing sauce to set and flavors to meld.

Notes

  • Chicken cooks more evenly when you pound the breasts to a uniform thickness before seasoning.
  • Frozen spinach works perfectly if fresh isn’t available, just squeeze out excess moisture before adding.
  • For a lighter version, swap heavy cream with half-and-half or Greek yogurt to reduce calories.
  • Add shredded cheese on top during the final uncovered baking time for extra crispy, golden edges.
