This oven baked 3-ingredient chicken diplomat is the kind of old-school dinner that earns a permanent spot in the family rotation because it is easy, dependable, and somehow tastes bigger than the effort involved. It has that classic church-supper, Sunday-dinner feel: chicken baked until the skin turns glossy and caramelized under a sweet-tangy sauce, with plenty of pan juices for spooning over the plate. For busy weeks, it is exactly the sort of recipe that feels like a little gift from an earlier generation of practical home cooks.

Serve this chicken with simple sides that can soak up the sauce, like mashed potatoes, white rice, buttered egg noodles, or baked potatoes. I also like it with green beans, corn, roasted carrots, or a crisp salad to balance the richness. If you are taking it to a potluck, a pan of dinner rolls on the side makes it especially easy to turn into a full meal.

Oven Baked 3-Ingredient Chicken Diplomat

Servings: 6

Ingredients

6 bone-in, skin-on chicken thighs

1 cup Russian dressing
1 envelope dry onion soup mix

Directions

1. Preheat the oven to 375°F and lightly grease a rectangular Pyrex baking dish. Pat the chicken thighs dry with paper towels and arrange them skin-side up in a single layer.

2. In a medium bowl, stir together the Russian dressing and dry onion soup mix until fully combined into a thick, tangy sauce.

3. Spoon the sauce evenly over the chicken thighs, coating the tops well. Bake uncovered for 45 to 55 minutes, or until the chicken is cooked through and the skin is browned and glossy.

4. Let the chicken rest for 5 minutes before serving, then spoon some of the pan sauce over each piece.

5. Serve hot with mashed potatoes, rice, or noodles and a green vegetable on the side.

Variations & Tips

Use different chicken pieces: Drumsticks or a mix of thighs and legs work well here too. Just keep the pieces similar in size so they cook at the same rate, and always check that the thickest piece reaches a safe internal temperature of 165°F.

Add a little extra sauce: If you love having plenty of sauce for rice or potatoes, use 1 1/2 cups of Russian dressing instead of 1 cup. The onion soup mix still brings enough seasoning, and the extra sauce keeps the dish especially potluck-friendly.

Make it ahead: You can assemble the chicken and sauce in the baking dish a few hours ahead and refrigerate it until dinnertime. That is one of my favorite tricks on a busy Sunday, because all that is left to do is slide it into the oven.

Try a sweeter variation: For a more old-fashioned sweet-and-tangy flavor, stir a spoonful of apricot preserves into the dressing before coating the chicken. It melts right into the sauce and gives the finished dish a deeper glaze.

Broil for extra color: If the chicken is fully cooked but you want a little more browning on top, place the dish under the broiler for 1 to 2 minutes at the end. Watch it closely so the sugars in the dressing do not burn.
