This 5-ingredient slow cooker July Fourth feast is built around a raw beef flat iron steak and a handful of pantry staples, transforming an affordable cut into something tender, saucy, and worthy of a backyard gathering. Flat iron, cut from the shoulder, is well-marbled and holds up beautifully to low-and-slow cooking, soaking in bold flavors without drying out.
Here it’s nestled into a slow cooker with a tangy barbecue sauce, sweet-tart cherry preserves, a splash of cola, and bright pops of tricolor cherry tomatoes that echo the festive colors of the holiday. The result is a set-it-and-forget-it main dish so good your friends will absolutely ask how you made it.
Serve the shredded flat iron over soft brioche or potato buns with a crunchy slaw—classic cabbage, vinegar-based, or even a simple bagged coleslaw dressed up with extra black pepper and celery seed. On the side, think traditional July Fourth staples: grilled corn on the cob, a simple green salad, or a chilled pasta salad.
The sauce is slightly sweet and smoky, so it pairs nicely with something bright and acidic like pickles or quick-pickled onions. For drinks, a cold lager, iced tea with lemon, or a cherry-lime spritzer will echo the flavors in the pot without overwhelming them.
5-Ingredient Slow Cooker July Fourth Flat Iron Feast
Servings: 6

Ingredients
2 to 2 1/2 pounds raw beef flat iron steak, excess surface fat trimmed
1 1/2 cups thick barbecue sauce (smoky or hickory style)
3/4 cup cherry preserves (or seedless cherry jam)
1 cup cola (not diet)
1 1/2 cups tricolor cherry or grape tomatoes, whole
Directions
Place the raw beef flat iron steak flat in the bottom of a 5- to 6-quart slow cooker. If the steak is very long, you can fold it slightly so it fits, but keep it in a single layer as much as possible. You should see the steak centered with space around it for the other ingredients.
Scatter the whole cherry or grape tomatoes all around the steak in the bottom of the slow cooker. They should form a loose ring or cluster of small, brightly colored spheres around the meat. Leaving them whole lets them soften gently and burst into the sauce as they cook.
In a medium bowl, whisk together the barbecue sauce, cherry preserves, and cola until smooth and evenly combined. This mixture should be pourable but still a bit thick; the cola thins the sauce and helps with caramelization during the long cook.
Pour the barbecue-cherry-cola mixture evenly over the steak and tomatoes, making sure the beef is mostly coated and the tomatoes are nestled in the sauce. Use a spoon to nudge any exposed spots of steak down into the liquid so everything cooks evenly.
Cover the slow cooker with the lid and cook on LOW for 7 to 8 hours, or on HIGH for 3 1/2 to 4 hours, until the flat iron steak is very tender and easily pulls apart with a fork. Avoid opening the lid during the first few hours so the cooker maintains a steady temperature.
Once the steak is tender, use tongs to transfer it to a cutting board. Let it rest for about 5 minutes, then use two forks to shred the meat into bite-size pieces, pulling along the natural grain of the steak. Skim any excess fat from the surface of the sauce in the slow cooker if you like.
Return the shredded beef to the slow cooker, stirring it into the sauce and softened tomatoes until everything is well coated. Taste and adjust the seasoning with a pinch of salt or a splash of additional barbecue sauce if you prefer a smokier or sweeter finish.
Turn the slow cooker to WARM and let the shredded beef sit in the sauce for 10 to 15 minutes to absorb more flavor. Serve the saucy beef straight from the slow cooker, spooned over buns, rice, or roasted potatoes, making sure to include some of the burst tomatoes and extra sauce in each serving.
Variations & Tips
For a spicier version, stir 1 to 2 teaspoons of crushed red pepper flakes or a few dashes of your favorite hot sauce into the barbecue-cherry-cola mixture before pouring it over the steak (this would technically add another ingredient, so treat it as optional rather than part of the core five).
If you prefer a more savory, less sweet profile, choose a tangy, vinegar-forward barbecue sauce and reduce the cherry preserves to 1/2 cup, adding a splash of apple cider vinegar at the end of cooking to brighten the flavor. You can also swap the cola for a dark cherry soda or a non-diet root beer for a slightly different but still holiday-friendly twist.
For a richer, more concentrated sauce, remove the shredded beef at the end of cooking and simmer the sauce in a saucepan on the stove for 5 to 10 minutes to thicken before returning the meat to the pot. Leftovers keep well: cool quickly, store in a shallow container, and refrigerate within 2 hours; use within 3 to 4 days or freeze for up to 3 months.
Reheat gently on the stovetop or in the microwave until steaming hot (165°F/74°C). As with any slow-cooked beef dish, start with a fully thawed flat iron steak for even cooking and food safety, and avoid lifting the lid repeatedly during cooking to maintain a safe, steady temperature. Use a clean cutting board and knife for the cooked meat, separate from any surfaces that touched the raw steak, and wash your hands and utensils thoroughly after handling the raw beef.
