This oven baked 3-ingredient chicken commodore is the kind of old-fashioned dinner that earns a permanent place in the family recipe box. It’s wonderfully simple, relying on just a few pantry-friendly ingredients to create tender chicken, deeply savory onion flavor, and a glossy brown sauce that tastes like it took far more effort than it actually did. Recipes like this became popular in mid-century home kitchens for a reason: they were affordable, dependable, and perfect for a busy Sunday dinner that still felt special.
Serve this chicken over mashed potatoes, buttered egg noodles, or fluffy white rice so none of the sauce goes to waste. On the side, simple green beans, roasted carrots, or a crisp salad balance the richness nicely, and warm dinner rolls are always a good idea for soaking up every last bit from the casserole dish.
Oven Baked 3-Ingredient Chicken Commodore
Servings: 6
Ingredients
3 pounds bone-in, skin-on chicken pieces
2 large sweet onions, sliced into rings
1 cup bottled French dressing
Directions
1. Preheat the oven to 350°F and lightly grease a white ceramic casserole dish large enough to hold the chicken in a single layer.
2. Spread half of the onion rings in the bottom of the casserole dish, then arrange the chicken pieces on top with the skin side up.
3. Scatter the remaining onion rings over the chicken, then pour the French dressing evenly over everything, making sure each piece gets coated.
4. Cover the dish tightly with foil and bake for 45 minutes.
5. Remove the foil, spoon some of the pan sauce over the chicken, and continue baking uncovered for 30 to 40 minutes, or until the chicken is fully cooked, tender, and nicely glazed, and the onions are soft and caramelized around the edges.
6. Let the chicken rest for 5 to 10 minutes before serving so the sauce settles slightly. Spoon the onions and sauce over each piece when plating.
Variations & Tips
Use boneless chicken: If you want a slightly quicker weeknight version, boneless skinless chicken thighs work well. Start checking for doneness earlier since they usually cook faster than bone-in pieces.
Make it ahead: You can assemble the chicken, onions, and dressing in the casserole dish a few hours ahead and refrigerate it until dinner time. That little bit of prep in advance is especially helpful on busy Sundays or work nights.
Add a pantry boost: Even though the classic version keeps it to three ingredients, a sprinkle of black pepper, paprika, or garlic powder can add a little extra depth without changing the spirit of the recipe.
Best onion choice: Sweet onions give the finished dish that mellow, almost jammy flavor that makes the sauce so memorable. Yellow onions also work, but they’ll bring a slightly sharper bite.
Serving tip: This is one of those dinners that tastes even better with something starchy underneath it. If I’m trying to stretch the meal for my family, I serve it over rice or noodles and make sure every spoonful of sauce gets used.
