This oven-baked creamy leek chicken is one of those low-effort, high-reward weekend dishes that feels celebratory without keeping you in the kitchen all day. Bone-in chicken thighs stay wonderfully juicy while sliced raw leeks soften and sweeten in the oven, soaking up the pan juices and cream. The method is as simple as it sounds: scatter the leeks around the raw chicken, add three more pantry-friendly ingredients, and slide the ceramic baking dish into the oven. The result is a cozy, Midwestern-style comfort meal with a French-leaning flavor profile that disappears from the table faster than just about anything else I make.
Serve the creamy leeks and chicken spooned over a starch that can catch all the sauce—mashed potatoes, buttered egg noodles, or simple steamed rice are perfect. Add a bright, crunchy side like a lemony green salad, roasted green beans, or steamed broccoli to balance the richness. A dry white wine or sparkling water with a squeeze of lemon works nicely alongside, and if you have crusty bread on hand, it’s ideal for mopping up the last of the cream and pan juices.
Oven-Baked 5-Ingredient Creamy Leek Chicken
Servings: 4

Ingredients
6 bone-in, skin-on chicken thighs (about 2 1/2 to 3 pounds total)
3 large leeks, white and light green parts only, thinly sliced and well rinsed
1 cup heavy cream
2 tablespoons olive oil
1 1/2 teaspoons kosher salt, plus more to taste
1 teaspoon freshly ground black pepper
Directions
Preheat your oven to 400°F (200°C). Place a medium-to-large ceramic baking dish (about 9x13 inches) on the counter so it’s ready to go.
Prep the leeks: Trim off the dark green tops and root ends. Slice the white and light green parts into thin rounds. Place the slices in a bowl of cool water, swish well to loosen any grit, then lift them out with your hands or a slotted spoon and drain thoroughly on a clean kitchen towel or in a colander.
Pat the chicken thighs dry on all sides with paper towels. This helps the skin brown and keeps the sauce from getting watery.
Drizzle 1 tablespoon of the olive oil over the bottom of the ceramic baking dish. Scatter the sliced raw leeks evenly around the dish, creating a loose bed that mostly covers the bottom.
Nestle the raw bone-in chicken thighs, skin-side up, directly on top of and among the leeks, leaving a little space between each piece so the heat can circulate.
Drizzle the remaining 1 tablespoon olive oil over the chicken thighs. Sprinkle the kosher salt and black pepper evenly over both the chicken and the exposed leeks.
Pour the heavy cream gently around the chicken into the leeks, avoiding pouring directly over the chicken skin so it can brown. The cream should pool around the leeks and come about halfway up the sides of the thighs, not submerge them.
Transfer the ceramic baking dish to the preheated oven and bake, uncovered, for 40 to 50 minutes, or until the chicken skin is deep golden, the leeks are very tender, and the cream has thickened into a sauce. The internal temperature of the thickest part of the thighs should reach at least 165°F (74°C).
If the chicken is cooked through but you’d like more color on the skin, move the dish to the upper third of the oven and broil on high for 2 to 3 minutes, watching closely to prevent burning.
Remove the dish from the oven and let the chicken rest for about 5 to 10 minutes. During this time, the sauce will thicken slightly more. Taste a bit of the creamy leeks and adjust seasoning with a pinch more salt or pepper if needed, then serve the chicken with plenty of leeks and sauce spooned over each portion.
Variations & Tips
For extra flavor without adding more core ingredients, you can tuck a few peeled garlic cloves or a sprig of fresh thyme or rosemary between the leeks and chicken before baking. A squeeze of lemon over the finished dish brightens the richness of the cream and leeks. If you prefer a lighter version, you can replace half of the heavy cream with chicken broth; the sauce will be thinner but still flavorful. Boneless, skinless thighs can be used, but they’ll cook faster (start checking around 25 minutes) and won’t develop the same crispy top. If using breasts, choose bone-in, skin-on and watch closely to avoid overcooking. For a slightly smoky note, add a small pinch of smoked paprika over the chicken with the salt and pepper. Food safety tips: Always wash leeks thoroughly, as they often trap grit between layers. Keep raw chicken separate from other ingredients and wash your hands, cutting boards, and knives with hot, soapy water after handling it. Use a food thermometer to ensure the chicken reaches at least 165°F (74°C) at the thickest part, not touching the bone. Refrigerate leftovers within 2 hours and reheat until piping hot before serving again.
