This oven baked 4-ingredient chicken tivoli is the kind of retro dinner that earns a permanent spot in the weeknight rotation because it delivers big flavor with barely any prep. Recipes like this were popular in the 1960s for a reason: a handful of pantry staples, a baking dish, and the oven did most of the work. It has that nostalgic, company-worthy feel my grandmother loved, with tender chicken, sweet onions, and a glossy baked-on sauce that tastes like you fussed far more than you actually did.
Serve this chicken with buttered egg noodles, fluffy rice, or mashed potatoes to catch every bit of the savory sauce. For summer-company vibes, add a simple green salad, steamed green beans, or corn on the cob, and if you want to lean into the vintage supper-club feel, a chilled glass of iced tea or crisp white wine fits right in.
Oven Baked 4-Ingredient Chicken Tivoli
Servings: 6
Ingredients
2 1/2 to 3 pounds bone-in, skin-on chicken thighs
2 large yellow onions, thinly sliced
1 cup bottled French dressing
1 packet dry onion soup mix
Directions
1. Preheat the oven to 350°F and lightly grease a rectangular Pyrex baking dish. Spread the sliced onions evenly across the bottom of the dish.
2. Arrange the chicken thighs skin-side up over the onions in a single layer.
3. In a small bowl, stir together the French dressing and dry onion soup mix until combined, then spoon the mixture evenly over the chicken.
4. Bake uncovered for 55 to 70 minutes, or until the chicken is deeply glazed, the onions are tender and caramelized, and the chicken reaches 165°F in the thickest part.
5. Let the dish rest for 5 minutes before serving, then spoon some of the pan sauce and onions over each piece.
Variations & Tips
Use boneless chicken: Boneless skinless thighs work well if that is what you have on hand. Start checking for doneness around 35 to 45 minutes so they stay juicy.
Add a little freshness: A sprinkle of chopped parsley or a squeeze of lemon right before serving brightens the rich, sweet-savory sauce and makes the finished dish feel a little lighter.
Make it ahead: You can assemble the onions, chicken, and sauce in the baking dish a few hours in advance and refrigerate it until dinner. That makes this especially handy for busy workdays or when you are expecting guests.
Prevent over-browning: If the top starts getting too dark before the chicken is done, loosely tent the dish with foil for the remainder of the baking time.
Turn it into a fuller meal: Tuck small potatoes or thick-cut carrots around the chicken before baking if you want a one-dish dinner. They will soak up the flavorful juices as everything cooks.
