Casserole

Instructions 

Gluten-Free Fried Onions Step

  • Thinly slice onions.
  • Add milk (or dairy-free milk) and vinegar to make buttermilk to a pie pan or shallow dish and allow to sit for 2-3 minutes.
  • Add the onions to the buttermilk and soak for 5-10 minutes.
  • In a plastic storage bag add the gluten-free flour, cornstarch, seasoned salt, and mix well.
  • In a large pan heat vegetable oil to 190°C degrees.
  • Add the buttermilk soaked onions to the flour mixture in the plastic bag and turn the bag over and over until the onions are well coated.
  • Add the battered onions to oil, frying in batches, until golden brown.
  • Remove the onions from oil with a slotted spoon and drain on a paper towel-lined plate.

Casserole

  • Pre-Heat your oven to 175°C and spray a casserole dish with cooking spray.
  • In a small bowl mix together the gluten-free cream of mushroom soup (or gluten-free and dairy-free soup), Worcestershire sauce, milk (or dairy-free milk) and pepper until smooth.
  • Add the drained canned green beans to the casserole dish.
  • Pour the soup mixture over the green beans.
  • Sprinkle 1 cup of the gluten-free fried onions over the soup and gently stir to mix the ingredients together.
  • Place on the middle rack and bake for 25 minutes.
  • Sprinkle with the remaining gluten-free fried onions and bake for another 10-15 minutes until bubbly and the sides of the casserole start to brown.
  • Store leftovers in an air-tight container and refrigerate.
  • Leftovers can be re-heated the microwave or oven.

Notes

  • If you do not want to make your own gluten-free fried onions, and you can’t find them at the grocery store you could use crushed Funyuns instead. Funyuns are gluten-free, but they are not dairy-free.
  • If you’re using fresh green beans, trim, cut, and briefly boil or microwave them. For frozen green beans, cook them until tender-crips, about 5 minutes.
  • You can make it dairy-free/ vegan by substituting milk for the cream of mushroom soup recipe and the onion toppings. You may have to make a homemade dairy-free soup.
  • Store leftovers in an airtight container in the refrigerator for up to 3-4 days.
