How to Make Cheesy Onion Bake

  1. Preheat oven to 350°F (175°C).
  2. Thinly slice 3 large Vidalia onions (about 3 cups sliced).

  5. Whisk in 1/4 cup all-purpose flour until smooth. Cook for 1 minute, stirring constantly.

  8. Pour the cheese sauce evenly over the onions in the casserole dish.
  9. Bake uncovered for 60-70 minutes, or until the onions are tender and the topping is lightly golden brown.
