FAQs
Can I use fresh onions instead of French fried onions?
Yes, but the classic crispy topping will be missing. If using fresh onions, sauté them first until caramelized to get a similar flavor and sweetness.
Is it possible to make this recipe gluten-free?
To make it gluten-free, choose gluten-free cream of chicken soup and substitute the French fried onions with gluten-free crispy onion toppings or crushed gluten-free crackers.
