Green Bean Casserole

Green Bean CasseroleSome of the holiday dishes can be made ahead and Green Bean Casserole is definitely one that works well being made a day or two ahead. Have you tried Green Bean Cassrole? What are your thoughts on this mushroom and saucy dish?

You could prep the mushroom and sauce portions two days ahead and refrigerate making prepping this a breeze on the day. Or you could make the entire dish except for that topping a whole day ahead and heat in your oven with the toppings just before serving.

This entire dish relies on homemade meaning you control every ingredient and element in it and that means if you like a different hardy herb, toss that in or double the mushrooms if you want it to be super mushroom heavy, work to your palate and this will still be a stellar dish!

Why you’ll love this

Easy prep

Overall, despite homemaking the béchamel and roasting the mushrooms, this is still pretty low on prep when you consider you’re making the entire dish from scratch.

Fresh bean flavor

Despite cooking the beans and tossing with all the flavors together, the crunchy fresh green beans will still have a strong and perfect crunch that we love with our beans.

How to prepare Green Bean Casserole

  • Roast em: Roast your mushrooms and garlic.
  • Blanche your beans: Blanche em until lightly cooked.
  • Béch-a-mel: Make your béchamel.
  • Toss: Toss the beans, mushrooms and béchamel together in your baking dish.
  • Cover and bake: Cover your baking dish with aluminum foil and bake.
  • Finish: Remove the foil, toss over the onions and cheese and bake until golden.
  • Serve up: Serve up and dig in!

Tips for the best Green Bean Casserole

Homemade crispy onions: Shallots are best here and for the quantity you need in this recipe, you’ll want to peel 2 large shallots and slice into half moons.

Pour 1 cup neutral oil (sunflower is best) into a small saucepan on medium high heat until you see ripples across the oil.

Toss in 1 handful of the onions where they should be simmering in the oil and stir to cook evenly for 1 1/2 – 2 minutes until lightly golden.

Remove and place on paper towels to drain.

Repeat with the remaining shallots in handfuls until all are crispy.

These are best covered and consumed within 1 day of being made.

Make ahead elements of this dish: You can absolutely oven roast the mushrooms 2-3 days ahead of assembling, simply cover and refrigerate until you need them.
