Sarah’s Tips & Variations

  • Gravy Swap: Use onion gravy mix for even more onion flavor.
  • Add Mushrooms: 2 cups of sliced mushrooms will make the dish more heartier
  • Swap the steak: Use chuck, round steak, or even cube steak.
  • Make it creamy: Stir in a dollop of sour cream or cream cheese at the end.

My Serving Suggestions

Choose a hearty carb-loaded side like steamed white rice, mashed potatoes, or egg noodles to serve the steak and onions over. We also love to eat this with baked potatoes (such an easy side).

Add an easy vegetable, such as slow cooker baby carrots or green bean casserole.
