The beauty of this slow cooker cube steak is in how it transforms over hours of gentle simmering. The beef becomes so tender it practically melts in your mouth, while the rich, savory gravy—packed with the earthy flavors of mushrooms, onions, and garlic—elevates every bite. It’s a dish that doesn’t just taste good—it delivers a depth of flavor that makes you want to savor every last spoonful.

What You Should Know Before Making This Recipe

Main Ingredients: Cube steak, onions, mushrooms, onion soup mix, cream of mushroom soup, water, garlic, cornstarch.
Quick Steps: Layer vegetables and steak in the slow cooker, mix soup and seasonings, pour over steak, and cook for 6-8 hours.
Total Time & Yield: 8 hours for 4 servings.

Why This Recipe

Our recipe includes sliced fresh onions and mushrooms, which add a rich, earthy depth of flavor.

Many other recipes skip this step, using only canned ingredients, which can result in a less fresh, more one-note flavor.

Additionally, the use of garlic in our recipe adds a more dynamic flavor layer. Garlic enhances the savory profile and pairs beautifully with the onion and mushroom base.

Many other cube steak recipes overlook garlic as a key ingredient, resulting in a dish that can feel a bit one-dimensional.

This recipe’s flexibility also sets it apart. Whether you prefer serving it over egg noodles, rice, or mashed potatoes, the gravy clings perfectly to any base, making it a versatile family favorite.

Ingredients

1 large onion, sliced
8 ounces cremini or baby bella mushrooms, sliced
1½ to 2 pounds cube steak
1 ounce onion soup mix
1 can cream of mushroom soup
1 cup water
½ teaspoon black pepper
½ teaspoon seasoned salt
2 teaspoons minced garlic
1 tablespoon cornstarch, dissolved in 1 tablespoon water

Instructions

In a 6-quart slow cooker, arrange the onion and mushroom pieces. Place the cube steak over the top of the vegetables. You can layer the steak pieces if needed.
In a separate bowl, whisk together onion soup mix, cream of mushroom soup, water, black pepper, seasoned salt, and minced garlic.
Pour soup mixture over the cube steak.
Cover and cook on high for 6 hours or on low for 8 hours.
During the last hour of cooking, whisk together the cornstarch and water and stir into the gravy mixture in the crockpot. Continue cooking (turning the slow cooker up to high if cooking on low) and cook for another 30 minutes to 1 hour, until the gravy thickens.
Serve over egg noodles, rice, or mashed potatoes.

Notes

The onions will take a while to cook down into nice soft caramelized onions, so adding them at the start of slow cooking is the perfect timing.
Because we’re adding the onion soup mix, do not add more salt to the recipe than the specified ½ teaspoon seasoned salt.
The longer you cook cube steak in the slow cooker, the more tender it will be. We found it was quite tender at the 6-hour mark.
