My neighbor learned this from her grandmother who survived the depression. The onions turn into the most incredible sweet sauce

This Slow Cooker 3-Ingredient Chicken and Onions recipe is a simple, hands-off way to create tender, flavorful meat using just a few basic ingredients. As the dish cooks, the onions soften and release their natural moisture, creating a rich, savory sauce that keeps the chicken juicy and full of flavor. The result is fall-apart tender chicken with a naturally sweet, onion-rich base.
Slow Cooker 3-Ingredient Chicken and Onions
Ingredients:
- 3–3½ lbs chicken pieces (bone-in, legs or thighs)
- 3 large yellow onions, thinly sliced
- 1 tbsp kosher salt, divided
Step-by-Step Directions:
Step 1: Base Layer
Spread one-third of the sliced onions across the bottom of the slow cooker and sprinkle lightly with salt.
Tip: This layer helps keep the chicken from sticking and adds flavor as it cooks.
Step 2: Layer the Ingredients
Pat the chicken dry and place half of the pieces on top of the onions, skin-side up. Sprinkle with salt. Add another layer of onions, followed by the remaining chicken and salt, then finish with the rest of the onions on top.
Tip: Layering helps the chicken cook evenly while the onions release moisture and flavor throughout the dish.
Step 3: Cook
Cover and cook on LOW for 6–8 hours or on HIGH for 3½–4 hours. No extra liquid is needed.
Step 4: Finish the Dish
Carefully remove the chicken and stir the softened onions and juices until combined into a rich sauce. Serve the chicken with the onions spooned over the top.
