This 5-ingredient oven chicken is the kind of dependable supper that feels right at home on a busy weeknight or a cozy Sunday table. Inspired by the practical, make-do spirit of 1940s ration-book cooking, it turns a package of bone-in chicken thighs and a few pantry staples into a rich, savory baked meal with hardly any fuss. Everything goes straight into one glass casserole dish, and the oven does the heavy lifting while the sauce thickens around the chicken.
Serve this chicken with mashed potatoes, buttered noodles, rice, or a slice of simple bread to catch every bit of the sweet-and-savory sauce. For vegetables, green beans, peas, glazed carrots, or a crisp cabbage slaw all work nicely and help round out the plate with a little freshness.
5-Ingredient Oven 1940s Ration Book Chicken
Servings: 6
Ingredients
6 raw bone-in chicken thighs, skin-on
Directions
1. Preheat the oven to 375°F. Lightly grease a 9x13-inch glass casserole dish, then arrange the raw chicken thighs in a single layer, skin side up.
2. In a medium bowl, stir together the ketchup, dry onion soup mix, brown sugar, and water until well combined.
3. Pour the sauce evenly over the chicken thighs, making sure each piece is well coated.
4. Bake uncovered for 50 to 60 minutes, or until the chicken is cooked through and reaches 165°F in the thickest part. Spoon some of the sauce over the chicken halfway through baking for extra color and flavor.
5. Let the chicken rest for 5 minutes before serving. Spoon the pan sauce over the top and serve hot with your favorite sides.
Variations & Tips
For a less sweet sauce: If your family prefers a more savory finish, reduce the brown sugar to 2 tablespoons. The sauce will still glaze nicely but taste a little more old-fashioned and tangy.
For picky eaters: Trim away any extra skin before baking if your table prefers a less rich bite. You can also spoon a little extra sauce over rice or noodles so every plate gets plenty of flavor.
For easy cleanup: Let the casserole dish soak in warm water after dinner since the baked-on sauce can cling around the edges. A glass dish works especially well here because you can keep an eye on how the sauce is bubbling and thickening.
For food safety: Because you are starting with raw bone-in chicken thighs, always check doneness with a meat thermometer instead of relying on color alone. If the sauce is getting too dark before the chicken is done, loosely tent the dish with foil for the last part of baking.
