A blanquette is a classic French stew of veal, chicken or lamb with mushrooms in a velvety sauce. This concept has been adapted to the slow cooker to make a lightened-up version using chicken thighs. Just a little whipping cream (which is less inclined to break down than lighter creams and gives more density to the sauce) adds richness. This is delightful over egg noodles.
Make Ahead Tip: Prepare through Step 4 up to adding the peas and parsley. Cover and refrigerate for up to 2 days or freeze for up to 3 months. Thaw in the refrigerator, if necessary, and reheat on the stovetop, in a microwave or in the oven; just before serving, stir in peas and parsley.
