Ingredients
- 1 flat iron steak
- 1 cup beef broth
- 1 packet dry onion soup mix
- 1 can cream of mushroom soup
- 1 small onion, sliced
- 2 cloves garlic, minced
- 1 tablespoon Worcestershire sauce
- ½ teaspoon black pepper
Instructions
Place the flat iron steak directly into the slow cooker.
Add the sliced onion and minced garlic around the steak. Pour the beef broth over and around the meat.
Add the cream of mushroom soup, dry onion soup mix, Worcestershire sauce, and black pepper. Gently spread the ingredients around the steak so the flavors can combine as everything cooks.
Cover the slow cooker and cook on LOW for 6–8 hours, or until the beef is tender and cooked to your desired texture.
Once the steak is ready, carefully remove it from the slow cooker and allow it to rest for a few minutes. Slice the beef against the grain and spoon some of the flavorful cooking juices over the top before serving.
What Makes This Recipe So Flavorful?
The combination of beef broth, onion soup mix, garlic, and Worcestershire sauce creates a savory base that complements the natural flavor of the steak. The cream of mushroom soup adds richness and helps create a creamy, flavorful sauce.
As the ingredients slowly cook together, the steak absorbs the surrounding flavors while the onions and garlic become tender. The cooking juices can then be spooned over the sliced beef for an extra boost of flavor.
What to Serve With Slow Cooker Flat Iron Steak
This tender beef is incredibly versatile and can be served with many classic sides. Mashed potatoes are an especially good choice because they soak up the rich sauce.
You can also serve it with roasted potatoes, steamed vegetables, green beans, rice, or crusty bread. For a lighter dinner, pair the steak with a simple green salad or your favorite roasted vegetables.
Tips for the Best Results
For the best texture, allow the steak to cook until it is tender rather than relying only on a specific cooking time. Slow cookers can vary in temperature, so the exact cooking time may differ slightly.
When slicing the steak, cut against the grain. This shortens the muscle fibers and makes each bite easier to chew.
You can also let the sliced beef sit in the cooking juices for a few minutes before serving. This helps keep the meat moist and allows it to absorb even more of the savory sauce.
An Easy Family Dinner
The beauty of this slow cooker recipe is that it transforms simple ingredients into a satisfying meal with very little effort. Once everything is added to the slow cooker, you can let it cook while you take care of the rest of your day.
Tender beef, savory onions, garlic, and a rich creamy sauce make this a comforting dinner that feels much more complicated than it really is.
If you’re always looking for simple slow cooker meals that the family will actually get excited about, this Flat Iron Steak recipe deserves a spot in your dinner rotation.
