Green bean casserole

[azurelunatic]

Taken from a magazine page that's been stuck to the refrigerator for a while, but I don't think we've actually made it. This is going in here so I can toss the paper.

1 onion, thinly sliced
butter / etc
2 lbs green beans in their final form
(1 lb button mushrooms, cleaned and sliced)
3 tablespoons starch (arrowroot, tapioca)
1 1/2 cups chicken or vegetable stock
1 1/2 cups heavy cream
salt & seasonings to taste

Preheat oven to 425F, rack in the middle
Toss onion with grease and seasonings/salt
spread onions on baking sheet and roast 20 mins
stir onions
roast another 15 minutes or until onions lose most of their moisture and start browning
Remove from oven and set aside
Reduce oven heat to 375F
Meanwhile, steam the green beans until tender
Drain and rinse with cold water
Set aside

If you're going to do mushrooms, knock yourself out - cook until juicy

If not, start heating a small amount of stock
Slowly add your thickener and stir until incorporated

Gradually add the rest of the stock and then the cream, stirring the fuck out of any lumps if they threaten to form

Reduce heat and simmer until thickened

Mix with green beans and pour into baking dish (this specifies 13x9 inches).
Put the onions on top.
Bake until bubbling (20-25 minutes)

This is gluten free and pepper free unless you add something containing those; it's not allium free.
