Spray the slow cooker with nonstick cooking spray. Place all ingredients into the slow cooker EXCEPT the cornstarch. Cover and cook on low for 6 to 8 hours.
6 cube steaks, 20 ounces cream of mushroom soup, 1 ounce onion soup mix, ½ cup water
Stir together the cornstarch and water. Remove the lid and add the slurry to the slow cooker. Stir to combine then re-cover and continue cooking for 30 minutes or until the gravy is thickened.
2 tablespoons cornstarch
Notes
You can use beef broth instead of water for even more depth of flavor.
While not required, some people like to sear the cube steak in a hot skillet with a bit of oil before placing it in the slow cooker. This can add a nice color and flavor to the meat.
To cook on the high setting, allow 3-4 hours.
Serve with mashed potatoes, rice, noodles, or warm crusty bread. These sides can soak up the flavorful gravy.
Garnish with chopped fresh parsley or green onions for a pop of color and freshness.
