This 5-ingredient slow cooker homestyle steak supper is the kind of comforting meal that feels especially welcome on a busy day, because the slow cooker does most of the work while the steak turns tender in a rich, savory gravy. Using a whole flat iron steak keeps the prep simple, and with just a few pantry staples, you get a hearty, family-style dinner that tastes like it took much more effort than it did.
Serve this steak supper over mashed potatoes, buttered egg noodles, or fluffy rice so none of that savory gravy goes to waste. A simple side of green beans, glazed carrots, corn, or a crisp salad rounds it out nicely, and warm rolls or sliced bread are always a good idea for mopping up the last bit from the plate.
5-Ingredient Slow Cooker Homestyle Steak Supper
Servings: 4 to 6
Ingredients
1 whole flat iron steak, about 1 1/2 to 2 pounds
1 packet onion soup mix, about 1 ounce
1 can cream of mushroom soup, 10 1/2 ounces
1 cup beef broth
2 tablespoons Worcestershire sauce
Directions
1. Place the whole flat iron steak in the bottom of your slow cooker insert.
2. In a medium bowl, stir together the onion soup mix, cream of mushroom soup, beef broth, and Worcestershire sauce until well combined.
3. Pour the mixture over the steak, covering as much of the meat as possible. Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours, until the steak is very tender.
4. Once cooked, transfer the steak to a cutting board and slice or shred it into serving pieces. Spoon some of the gravy from the slow cooker over the top before serving.
Variations & Tips
For extra onion flavor: Add a sliced onion under or over the steak before cooking. It melts right into the gravy and makes the whole dish taste even more homestyle.
For a thicker gravy: If you like a more spoon-coating sauce, remove the cooked steak and whisk 1 tablespoon cornstarch with 1 tablespoon cold water, then stir it into the hot liquid in the slow cooker. Cover and cook on high for about 10 to 15 minutes until thickened.
For picky eaters: Slice the steak into bite-size pieces before serving and spoon the gravy lightly over just part of it. That way everyone can add as much sauce as they like on their own plate.
For easy serving: This recipe is especially good over mashed potatoes or egg noodles because they catch every bit of gravy. If your flat iron steak is on the larger side, you can trim it into a couple of big pieces so it fits comfortably in the cooker without overlapping too much.
