  • 10.5 ounce condensed cream of mushroom soup
  • 1/2 cup milk

  • 8 ounce sliced mushrooms (optional)
  • 1.5 cups French fried onions


Instructions

  2. Cover and cook on low for 4 to 5 hours or until the green beans are tender.
  3. Stir the casserole and taste, adjusting seasoning with salt and pepper if desired.
  4. Sprinkle French fried onions over the top, cover, and cook on high for 15 to 20 minutes until the onions are crisp.
