I’ve stopped looking at my recipe (from Buvette in New York), but pretty sure it was something like this (feeds 8):
soak 16 chicken legs and thighs (so 8 pieces each), bone in skin removed, about 8 pieces of smashed garlic, and two rosemary stems, in a bottle of wine overnight (I use Chablis, Riesling common as well)
Take out chicken and garlic from wine, discard rosemary, and reserve your wine. Slice the garlic if you want. pat chicken dry, salt and pepper.
Cook down 1/2 pound bacon cut into little pieces in 1/4 cup olive oil. Remove with slotted spoon.
Brown chicken in batches in the bacon fat. Set aside
add something like 10-16 mushrooms of your choosing, along with the garlic and a couple pinches salt, and cook over medium until it looks good.
Add chicken and bacon back to pot. Add the reserved wine and enough water to mostly cover chicken (about a cup or so), and another couple pinches salt. Bring to boil and reduce, cover pot and simmer for about 40 mins.
Now add about a cup of pearl onions, and a pinch or two of salt. Simmer for another 10-15 until everything is tender.
Here is where I take out the chicken and pull it, and add back in. Some people would leave bone in.
With your finger, whisk equal parts room temp butter and flour, 2-4TB of each depending upon how thick you want the stew. Add a cup or so of the cooking liquid and whisk. Mix into stew and continue to simmer on low until desired thickness. Check for more salt.
Serve along side favorite potato dish.
Note 1: the above is obviously very fatty. You could lighten by pouring out quite a bit of the bacon fat. Won’t be as great, but your cardiologist would thank you.
Note 2: just replace white wine with burgundy or cote du Rhône, and you have the heavier classic coq.
Note 3: I peel fresh pearl onions, but it takes forever and frozen works too. I find there is a weird bite to frozen, but might just be in my head.
