This 5-Ingredient Slow Cooker 1960s Star-Spangled Casserole is the kind of comforting supper that feels right at home on a busy weeknight or a casual family gathering. Using raw skin-on chicken pieces and a handful of pantry staples, it cooks low and slow into a rich, savory meal with that old-fashioned casserole charm people have loved for generations. It has a nostalgic, budget-friendly feel that makes it especially appealing when you want something hearty, simple, and satisfying without a lot of fuss.
This casserole is wonderful served with fluffy mashed potatoes, buttered egg noodles, or steamed white rice to soak up the flavorful sauce. For a brighter plate, add green beans, glazed carrots, or a crisp side salad, and if you want to lean into the retro comfort-food feel, a warm dinner roll on the side makes the meal even more inviting.
5-Ingredient Slow Cooker 1960s Star-Spangled Casserole
Servings: 6
Ingredients
6 raw skin-on chicken pieces, such as thighs or drumsticks
1 can condensed cream of mushroom soup (10.5 ounces)
1 cup ketchup
1/4 cup prepared yellow mustard
1 small onion, thinly sliced
Directions
1. Lightly coat the inside of your slow cooker with cooking spray or a little oil if desired for easier cleanup. Arrange the raw skin-on chicken pieces in an even layer in the bottom of the slow cooker, skin side up when possible.
2. Scatter the sliced onion over the chicken so it cooks down into the sauce and adds a gentle sweetness.
3. In a medium bowl, stir together the condensed cream of mushroom soup, ketchup, and yellow mustard until smooth and evenly combined.
4. Pour the sauce over the chicken and onions, covering the pieces as evenly as you can. Place the lid on the slow cooker and cook on low for 6 to 7 hours or on high for 3 1/2 to 4 1/2 hours, until the chicken is fully cooked and very tender.
5. Once cooked, spoon some of the sauce over the chicken before serving. If you like, skim a little extra fat from the top of the sauce first. Serve hot with mashed potatoes, noodles, or rice.
Variations & Tips
For a milder flavor: If you are serving little ones or anyone who prefers gentler flavors, use a little less mustard and add an extra spoonful of condensed soup to keep the sauce creamy and balanced.
Add a vegetable: Sliced mushrooms or a layer of carrots can go right into the slow cooker with the onions, making this an even fuller one-pot meal without much extra work.
Crispier chicken skin: Slow cookers keep chicken wonderfully moist, but the skin stays soft. If you want a crisper finish, place the cooked chicken pieces on a baking sheet and broil them for 2 to 4 minutes before serving, then spoon the sauce over the top.
Make the sauce smoother: For a sauce with a more uniform texture, whisk the soup, ketchup, and mustard very thoroughly before pouring it over the chicken, and stir the finished sauce gently before serving.
Best chicken choices: Bone-in thighs and drumsticks hold up especially well in the slow cooker and stay juicy. Try to use similarly sized pieces so everything finishes cooking at about the same time.
