Pat the cube steaks dry using paper towels.

Season both sides with:

  • Salt
  • Black pepper
  • Garlic powder
  • Onion powder
  • Smoked paprika

Lightly coat each piece with flour.

The flour helps create a better texture and contributes to a thicker gravy.

Step 2: Brown The Cube Steak

Heat olive oil in a large skillet over medium-high heat.

Sear the cube steaks for:

2–3 minutes per side

until lightly browned.

They do not need to be fully cooked because they will finish in the slow cooker.

Transfer the steaks to the slow cooker.

Step 3: Cook The Onions and Mushrooms

Using the same skillet, add:

  • Sliced onions
  • Mushrooms

Cook for:

5–7 minutes

until softened and lightly golden.

Add garlic and cook for another:

30 seconds

until fragrant.

The browned bits from the steak add extra flavor.

Step 4: Prepare The Gravy

In a bowl, combine:

  • Beef broth
  • Cream of mushroom soup
  • Worcestershire sauce
  • Soy sauce
  • Melted butter

Whisk until smooth.

Pour the gravy mixture into the skillet with the mushrooms and onions.

Stir to combine.

Step 5: Slow Cook The Cube Steak

Pour the mushroom onion gravy over the cube steaks in the slow cooker.

Add:

  • Fresh thyme
  • Bay leaf

Cover and cook:

Low setting: 6–8 hours
High setting: 3–4 hours

The cube steak is ready when it is tender and easily cuts with a fork.

Step 6: Finish The Gravy

Remove the cube steaks carefully.

Stir the gravy well.

If you prefer a thicker consistency:

Mix:

  • Cornstarch
  • Cold water

to create a slurry.

Add it to the gravy and cook for another:

10–15 minutes

until smooth and thick.

  • Mashed potatoes
  • Rice
  • Egg noodles

Spoon plenty of onion mushroom gravy over the top.
