  • Brown the remaining canister of French fried onions in a skillet on the stove top. Set the skillet to medium high heat, stir the onions around until brown (about 3 minutes).

Notes

Frozen or Fresh Green Bean Instructions:
  • Use 10 cups fresh (trimmed and cut) or frozen green beans instead of canned.
  • Cook for 3.5 hours on high or until the green beans are tender.
Browning the onions in the oven:
If your slow cooker is oven safe (check your manual), sprinkle the remaining canister of French fried onions to the top of the casserole.
  • Remove the slow cooker insert from the heating element and place it in the oven WITHOUT the lid.
  • Cook for 10 minutes at 350°F or until the onions are browned.
  • OR place the onions in a small dish in the oven for 10 minutes or until browned, then sprinkle over the casserole.
Halving the recipe:
You can cut this recipe in half. You will only need to cook for 2 hours on high before adding the remaining onions.
