The Ultimate 5-Ingredient Slow Cooker July Fourth Flat Iron Feast

How to Make It: Step-by-Step

Step 1: Build the Flavor Base

Take your sliced sweet onion and scatter the rings evenly across the bottom of your slow cooker insert. This acts as a natural trivet for the meat, keeping it elevated and infusing the cooking juices with a savory, caramelized onion flavor.

Step 2: Season the Beef

Pat your flat iron steak dry with a paper towel. Generously rub the Montreal steak seasoning on all sides of the meat, pressing it firmly into the flesh so it forms a nice crust. Place the seasoned steak directly on top of the bed of onions.

Step 3: Pour and Glaze

In a small bowl, whisk together the bourbon BBQ sauce and the cherry cola until smooth. Pour the mixture directly over the steak, ensuring the meat is fully coated in the liquid.

Step 4: Cook Low and Slow

Cover the slow cooker with its lid. For the absolute best results, cook on LOW for 6 to 7 hours. If you are in a pinch for time, you can cook it on HIGH for 4 hours, but the low-and-slow method yields that classic, fall-apart texture that makes this a true "feast."

Step 5: Shred and Serve

Once the timer goes off, transfer the beef to a cutting board. You can either slice it into thick, juicy medallions or use two forks to shred it into a succulent pulled beef. Toss the meat back into the slow cooker for 10 minutes to let it soak up all the remaining caramelized barbecue juices.

How to Serve Your Feast

This flat iron feast is incredibly versatile for a July Fourth backyard bash. Pile the shredded beef high on toasted brioche buns topped with a scoop of crisp coleslaw for the ultimate holiday sandwich. Alternatively, serve the slices alongside classic summer sides like grilled corn on the cob, potato salad, and a cold slice of watermelon.

With only five ingredients and zero effort required on the day of the party, this recipe guarantees you can kick back, enjoy a cold drink, and celebrate freedom the right way—away from the stove
