Can I use canned green beans for green bean casserole?

Yes, but the texture and flavor won’t be as vibrant. Fresh or frozen green beans give a much better result.

Can I make green bean casserole the day before?

Absolutely. Assemble it ahead without the topping, then bake with onions added fresh.

How do I make green bean casserole gluten-free?

Use gluten-free flour in your sauce and buy gluten-free crispy onions (or make your own).

What can I use instead of French fried onions?

Try toasted panko breadcrumbs, crushed crackers, or caramelized onions.

Is this recipe suitable for vegetarians?

Yes! Just use vegetable broth and ensure your fried onions are meat-free.

Instructions

Blanch green beans in salted boiling water until bright green, then transfer to ice water to stop cooking.
In a skillet, sauté mushrooms, garlic, and shallots in butter until soft and aromatic.
Add flour to the skillet to form a roux, then gradually whisk in milk and broth to create a thick sauce.
Season the sauce with salt, pepper, and a touch of nutmeg.
Combine the green beans with the sauce and transfer to a greased baking dish.
Top evenly with crispy fried onions.
Bake at 375°F for 20–25 minutes until bubbly and golden brown.

Notes

Use frozen green beans if fresh aren’t available—just thaw and dry them well first.
For extra indulgence, add shredded Parmesan or Gruyère before baking.
To make ahead, assemble without onions and refrigerate for up to 2 days.
Use gluten-free flour and toppings for a gluten-free version.
Not ideal for freezing—topping may become soggy.
