So this recipe requires a little extra effort just because of the Crispy Fried Onions, but it’s totally worth it if you’re a green bean casserole fanatic and want to see it on your keto/low carb holiday dinner table.
I could have stopped with the Low Carb, Keto Crispy Fried Onions (and eaten them all then and there), but I forged onward for my husband’s sake and for Green Bean Casserole lovers everywhere.
The onions are a little tricky because they’re coated with coconut flour and parmesan cheese, so you don’t get that pretty golden color that you would from a can of French’s artificially-colored and -preserved fried onions. That’s totally okay with me though. I’ll take healthy over pretty, and the melted cheddar cheese on top helps too.
