Hairy Bikers Healthy Chicken Casserole

Hairy Bikers Healthy Chicken Casserole
Print Recipe

A lighter version of the classic comfort dish, this chicken casserole features tender chicken thighs simmered in a rich, creamy sauce flavored with leeks, carrots, and fresh thyme. The sauce is thickened naturally with a reduction of stock and a touch of cornstarch, keeping it low in fat but high in savory depth.

Ingredients

Scale
  • 1 1/2 lbs boneless skinless chicken thighs (about 6 thighs), trimmed of visible fat
  • 1 tbsp olive oil
  • 1 medium leek (about 8 oz), white and light green parts only, halved lengthwise and sliced 1/4-inch thick
  • 2 medium carrots (about 6 oz total), peeled and sliced into 1/2-inch rounds
  • 2 cloves garlic, minced
  • 1 1/2 tbsp all-purpose flour
  • 2 cups low-sodium chicken broth
  • 1/2 cup whole milk (2% or whole, not skim)
  • 1 tbsp cornstarch
  • 1 tbsp cold water
  • 1 tsp fresh thyme leaves, or 1/2 tsp dried thyme
  • 1/2 tsp kosher salt, plus more to taste
  • 1/4 tsp freshly ground black pepper, plus more to taste
  • 1 tbsp unsalted butter (optional, for richer finish)
  • 1 tbsp fresh parsley, chopped (for garnish)

Instructions

  1. Pat the chicken thighs dry with paper towels and season both sides with 1/4 teaspoon of the salt and a pinch of pepper. This step removes moisture and ensures a good sear rather than steaming the meat.
  2. Heat olive oil in a large, heavy-bottomed pot or Dutch oven (at least 5-quart) over medium-high heat until the oil shimmers. Place the chicken thighs in a single layer (work in two batches if needed) and cook without moving for 4 minutes, until the underside is deep golden brown. Flip and cook another 3 minutes. Transfer the thighs to a plate and set aside. The browned bits stuck to the pot (fond) are essential for flavor.
  3. Reduce the heat to medium. Add the sliced leek and carrots to the pot. Cook, stirring occasionally, for 5 minutes until the leek softens and begins to turn translucent. If the pot looks dry, add 1 tablespoon of water to release the fond and continue scraping with a wooden spoon.
  4. Add the minced garlic and cook, stirring constantly, for 30 seconds until fragrant. Do not let the garlic brown or it will become bitter.
  5. Sprinkle the flour over the vegetables and stir well to coat. Cook for 1 minute, stirring constantly, to cook out the raw flour taste. The mixture will look dry and pasty.
  6. Slowly pour in the chicken broth while whisking vigorously to prevent lumps. Add the milk and continue whisking until the sauce is smooth and simmering. The sauce will thicken slightly as it heats.
  7. In a small bowl, whisk the cornstarch with the cold water to form a slurry. Pour the slurry into the simmering sauce while stirring. The sauce will thicken more in the next few minutes. Stir in the thyme, remaining 1/4 teaspoon salt, and 1/4 teaspoon pepper.
  8. Return the browned chicken thighs to the pot along with any juices that have accumulated on the plate. Nestle them into the sauce so they are mostly submerged. Bring the liquid back to a gentle simmer (small bubbles breaking the surface), then reduce the heat to medium-low.
  9. Cover the pot with a lid and let the casserole cook gently for 25 minutes. Check halfway through: the sauce should be at a low simmer, not a vigorous boil. After 25 minutes, the chicken should be tender and cooked through (internal temperature 165°F / 74°C when checked with an instant-read thermometer).
  10. Remove the lid and increase the heat to medium. Cook uncovered for 5 minutes to let the sauce reduce slightly and concentrate flavors. If a richer finish is desired, stir in the butter until melted. Taste and adjust salt and pepper as needed.
  11. Remove from heat and let rest 5 minutes before serving. This allows the sauce to settle and the flavors to meld. Garnish with fresh parsley.
  12. Serve over steamed rice, mashed potatoes, or with crusty bread to soak up the sauce. The casserole can also be served with a side of steamed green vegetables.

Notes

Storage: Refrigerate leftovers in an airtight container for up to 3 days. To freeze, cool the casserole completely, transfer to a freezer-safe container, and freeze for up to 3 months. Thaw overnight in the refrigerator. Reheat gently on the stovetop over medium-low heat, adding a splash of broth or water if the sauce is too thick, until the chicken reaches 165°F / 74°C. Alternatively, reheat in a 350°F / 177°C oven for about 20 minutes if the casserole is in an oven-safe dish. Avoid boiling the sauce when reheating or the cornstarch-thickened sauce may break.
