Preheat your 12-inch cast iron camp Dutch oven over 30-40 charcoal briquettes (or equivalent heat source). Keep a 2nd Dutch oven nearby (not on or over the heat but near the heat) as a warming pot (optional).
Add just enough oil to coat the bottom of the Dutch oven.
Gather all your prepared ingredients and perform any fireside preparations. Set out your 6-8 pieces of prepared chicken on a cutting board or other surface and season with poultry seasoning first, then do a light dusting of cornstarch.
Once the oil in the cast iron Dutch oven is hot and fry-ready (you’ll see wisps of smoke rising from the surface), pan fry 3-4 pieces at a time until golden brown on both sides. They do NOT have to be fully cooked at this point (better to remain a little raw). Store the pan fried chicken in a separate Dutch oven to keep warm.
We are about to start baking and need to have a full, fresh set of charcoal briquettes ready. Start a new batch of charcoal briquettes for baking. Set 24 - 26 briquettes in the charcoal chimney and get them fired up.
Remove any excess oil from the Dutch oven (a paper towel does quick work of this…don’t wipe…just pat the excess oil from the pan) and leave enough oil to saute the onions and garlic. Add the onions and garlic to the pot and sauté until translucent(ish).
Add your chopped green bell pepper, diced celery, and rice. Stir it all about for a few minutes to sauté and deglaze that pot.
Add the can of Cream of Mushroom Soup, the can of Cream of Chicken Soup. Fill both cans with beer (20 ounces of beer) and pour the beer in the pot. Then, add the Sour Cream and a tablespoon of Worcestershire Sauce.
Make sure all the ingredients except for the chicken are thoroughly blended. Then taste for saltiness. Add salt and pepper only if you need to. Your chicken has been brined and should be perfectly salty. Take a taste of the mixture in the pot and add salt and pepper as you enjoy a dish to taste. You may need to add some pepper but the soups that you added may have enough salt to “carry” this recipe.
If you added salt and/or pepper, thoroughly blend the mixture again. Make sure there are no grains of rice stuck to the sides of the Dutch oven. Any grains of rice outside the liquid will not cook. Level off all the ingredients in the pot at this point.
Add the chicken to the top and let the chicken rest on the top of the mixture. If, while sitting in the warming pot, any broth was created by the “waiting” chicken (the container or the Dutch oven you held the chicken in, pour that into the pot with the chicken and rice; just pour it in on the top; don’t worry about mixing it in.
Place the Dutch oven lid on the pot. Start with a fresh set of 24 charcoal briquettes. Arrange them for baking. Place 8 briquettes under the oven and 16 on the lid. Turn the pot and then the lid every 10 minutes.
Let the recipe cook until the chicken is 165°F / 75°C and the rice is completely cooked. If the rice is going to be underdone, it will be the rice closest to the top. Add beer and keep cooking if the rice needs more time.
Remove the pot from the heat and serve the chicken and rice hot straight from the camp cast iron Dutch oven.
