Coat 20 oz boneless thighs in 1 tsp paprika.
Heat a non-stick skillet over medium heat, add 1 tbsp olive oil, and sear the chicken for about 5 minutes, skin-side down. Set aside.
Add 2 oz chopped onions and sauté for about a minute or so.
Add 6 oz mushrooms, 6 oz carrots, 4 oz green peas, and 2 oz celery. Sauté for 2 minutes.
Deglaze the skillet with 1/4 cup white wine.
Add 2 tbsp flour, 2 tsp lemon juice, 2 tsp Dijon mustard, 1 tsp thyme, 1/2 tsp salt, and 1/2 tsp pepper. Stir to incorporate.
Add the chicken back. Pour in 2 cups unsalted broth, 1/4 cup whole milk, and 3 tbsp heavy cream. Stir to incorporate. Add 1 bay leaf, and turn the heat on high. As soon as it bubbles, turn it to low and leave to simmer for 25 minutes, uncovered.
Remove from the heat. Garnish with 2 tbsp parsley and enjoy.
