Make It Your Own

Sometimes I sneak in crispy bacon bits or a handful of sharp cheddar. Try cream of celery soup for a change or sprinkle some toasted almonds on top instead of onions. Your kitchen your rules.

Frequently Asked Questions

→ Can I make this ahead of time?

Yes, assemble without onion topping, refrigerate, then add onions and bake when ready.

→ Which green beans work best?

Fresh (blanched), frozen, or canned all work well. Fresh gives best texture but takes more prep.

→ How do I keep the onions crispy?

Add them only in the last few minutes of cooking. They'll brown nicely without getting soggy.

→ Does this need extra salt?

Usually not, as the soup and soy sauce provide plenty. Taste before adding any.

→ Can I make this in an air fryer?

Yes, cook at 350°F for 10 minutes, add onions, then 2 more minutes to brown.
