This 4-ingredient slow cooker 1960s ruby chicken is one of those set-it-and-forget-it dinners that feels like it came straight out of a retro church cookbook. You literally toss raw boneless skinless chicken breasts into the slow cooker, pour three simple pantry staples over the top, and let it bubble away into tender, sweet-tangy, ruby-red chicken that my husband always goes back for seconds on. The bright red color and fruity glaze are very much in the spirit of those fun 1960s “party chicken” recipes that used jams and sauces to make weeknights feel special, but this version keeps things streamlined and family-friendly.
This ruby chicken is lovely served over fluffy white rice, buttered egg noodles, or mashed potatoes so all that glossy red sauce has something to soak into. Add a simple green side like steamed green beans, roasted broccoli, or a tossed salad to balance the sweetness. If your family likes a little crunch, serve with buttered peas and some warm dinner rolls to mop up the extra sauce. Leftovers are great tucked into soft rolls for sandwiches or spooned into a bowl with rice and a handful of shredded lettuce for an easy lunch the next day.
4-Ingredient Slow Cooker Ruby Chicken
Servings: 4

Ingredients
2 pounds raw boneless skinless chicken breasts
1 cup seedless red raspberry jam or preserves (ruby red, slightly chunky)
1/2 cup ketchup
2 tablespoons reduced-sodium soy sauce
Directions
Place the raw boneless skinless chicken breasts in a single layer in the bottom of a 4- to 6-quart slow cooker. It’s fine if they overlap slightly, but try not to stack them too high so they cook evenly.
In a medium bowl, whisk together the red raspberry jam, ketchup, and soy sauce until the mixture is mostly smooth and well combined. The jam can stay a little chunky; that gives you those pretty ruby fruit bits on top.
Pour the ruby red sauce evenly over the chicken breasts, making sure each piece is coated. Use a spatula to scrape out every bit of sauce so it all ends up in the slow cooker.
Cover the slow cooker with the lid. Cook on LOW for 4 to 5 hours, or on HIGH for 2 to 3 hours, until the chicken breasts are cooked through and reach an internal temperature of 165°F (74°C) in the thickest part.
Once cooked, carefully remove the chicken breasts to a cutting board. If you like neat slices, let them rest for 5 minutes, then slice or leave them whole. If your family prefers shredded chicken, use two forks to shred the chicken right in the slow cooker.
Stir the sauce in the slow cooker so it’s smooth and glossy. Return the sliced or shredded chicken to the slow cooker and toss gently to coat in the ruby sauce. Let it sit on WARM for 5 to 10 minutes so the chicken soaks up some of the flavor.
Taste the sauce and adjust if needed: add a pinch of salt for more savoriness or a spoonful of extra jam if you want it sweeter. Serve the ruby chicken hot with plenty of sauce spooned over each portion.
Variations & Tips
For picky eaters, you can swap the raspberry jam for strawberry or grape jelly if that’s what your family prefers; just keep the bright red color so you still get that fun ruby look. If someone in your house isn’t a fan of strong soy sauce flavor, use 1 tablespoon soy sauce plus 1 tablespoon water to keep it milder. For a little kick, stir in 1/4 teaspoon red pepper flakes or a few dashes of hot sauce into the sauce mixture before pouring over the chicken. To make it slightly less sweet, reduce the jam to 3/4 cup and add 2 extra tablespoons ketchup. If you like a thicker, stickier glaze, remove the cooked chicken at the end and simmer the sauce in a small saucepan on the stove for 5 to 8 minutes until it reduces, then pour it back over the chicken. For a freezer-friendly version, place the raw chicken breasts and the mixed sauce together in a freezer bag, lay it flat to freeze, then thaw in the fridge overnight and dump everything into the slow cooker in the morning.
Food safety tips: Always start with raw chicken that has been kept refrigerated at or below 40°F (4°C) and never leave it out at room temperature for more than 2 hours (or 1 hour if your kitchen is very warm). Use a clean cutting board and knife just for the raw chicken, and wash your hands, utensils, and any surfaces that touched the raw meat with hot, soapy water before moving on to other tasks. Make sure the chicken reaches an internal temperature of 165°F (74°C) before serving; a simple instant-read thermometer is very helpful here. Do not cook this recipe from frozen chicken in the slow cooker, as it can stay too long in the temperature “danger zone” while thawing. Thaw frozen chicken in the refrigerator overnight before using. Store leftovers in a covered container in the refrigerator and use within 3 to 4 days, reheating until steaming hot before serving.
