This oven baked 4-ingredient chicken commodore is the kind of retro dinner that earns a permanent spot in the weekly rotation because it turns a handful of pantry staples into something that tastes far more special than the effort suggests. With its glossy savory glaze and soft, sweet onions, it has that comforting mid-century casserole charm that makes sense coming from an old church cookbook, and it is especially handy on busy nights when you want a hearty homemade meal without a long ingredient list.

Serve this chicken with mashed potatoes, buttered egg noodles, or simple white rice to catch all of the rich brown sauce. A side of green beans, peas, or a crisp salad helps balance the sweetness of the onions, and warm dinner rolls are perfect if you want to lean into the full old-fashioned supper feel.

Directions

1. Preheat the oven to 375°F and lightly grease a vintage-style ceramic or glass baking dish large enough to hold the chicken in a single layer.

2. Spread the sliced onions across the bottom of the dish, then nestle the chicken thighs on top.

Variations & Tips

Use chicken breasts: If you prefer white meat, use bone-in split chicken breasts and start checking for doneness around 40 to 45 minutes so they do not dry out.

Make it ahead: You can assemble the dish a few hours in advance, cover it, and refrigerate it until dinnertime, which is especially helpful on busy workdays.

Add extra onion: If your family loves soft baked onions as much as mine does, add a second sliced onion so there is more of that sweet savory layer under the chicken.

Serve over starches: The sauce is too good to waste, so this recipe is especially nice over rice, noodles, or mashed potatoes that can soak up every bit from the pan.
