Step 1 – Set your 5-7 quart cast iron Dutch oven and on medium heat (or a bit higher) over one burner. Use the lid or a bowl nearby the Dutch oven (and not over any heat) to "receive" the seared beef. We'll sear only part of the beef at a time.
Step 2 – Render the fat from the Lardons. Once they are a bit brown but not too crispy, transfer them to the upside-down lid or (right-side up) bowl; leave the rendered fat in the pot.
Step 3 – Increase the temperature from medium heat to medium-high heat and wait for the rendered bacon fat to just start smoking. For you folks with a surface thermometer 400-450°F (205-235°C) is the temperature we are shooting for.
Step 4 – Add SOME of the beef to the hot, slightly smoking pot. SIZZLE!! But, don’t add to much at once. We’re going to sear in batches.Sear each side of the beef chunks by searing-and-turning each as they brown. Use the thongs; they’ll make life easier. When each are seared and browned on all sides, transfer them to the nearby lid and start a new batch.Render the fat from more lardons or add a bit of oil as you need. Step 5 – Now, all the beef is seared and the bottom of that pot is covered with all that flavor. Leave it there! Reduce the heat to medium, add the onions (not the pearl onions) and the garlic, and deglaze the bottom of the cast iron Dutch oven.
Step 6 – Add the chunks of carrots at this point and, using the wooden spatula, mix everything all about and let things cook just a bit…not too long.We’re about to “get busy” adding most of the remaining ingredients. Turn the heat down a bit to keep from burning anything while we add the ingredients. Step 7 – Add the flour mixture to the pot, the tomato paste, all the beef, and however many browned bacon lardons you want to add back. Mix everything together and level off the ingredients.
Step 8 – Slowly pour in the room-temperature beer. It will “head up” but that’s okay. Mix everything in well and level off again.
Step 9 – Slowly pour in the beef broth BUT NOT ALL OF IT. Take your time to fill just to a bit over the top of the meat and vegetables. We want the end result to be a stew with the ingredients level and sticking out of the final stew.
Step 10 – Add the bay leaves and the herb Bouquet (or chopped / dried) and the salt and pepper. Keep in mind that there’ll be ingredients that you will use from time-to-time that have salt. We have plenty of time to test the saltiness and add salt as we cook.
Step 11 – Turn the heat down to medium low or even low. Cover the Dutch oven, and let it simmer for a few hours and stir things up a bit form time to time to avoid sticking as the stew thickens.
Step 12 – Okay, everything is in the pot except for the pearl onions and the mushrooms. We’ll tend to those in a bit. Let everything cook until the meat is tender and not chewy. We are looking for the consistency of an all-day-cooked roast and not the chewiness of a grilled steak. Once you have reached this point or are very close to it (2-3 hours), it’s time to do the pearl onions and the mushrooms.Go ahead and pull out the pearl onions and mushrooms to reach room temperature for later. Step 13 – After simmering for 30 minutes, check the saltiness. Use a spoon and dip out just some of the broth / liquid. Taste it. Do you need to add any salt? Do this again after 1 hour and you should have it spot on.
Step 14 – Using the Cast Iron Skillet (10.25” to 12”) (we are going to be braising the pearl onions and the mushrooms here at the end of the cook). Place the skillet on a medium high heat and add a bit of oil, remaining fat, or even more bacon lardons’ rendered fat. Add the room-temperature pearl onions and mushrooms to the hot, oiled skillet and add (slowly) about ¼ cup of liquid (beer, broth, stock, or even water). STEAM!!
Step 15 – Sauté the pearl onions and the mushrooms until they go from braising to searing and just at the caramelization “event” takes place. They should (the pearl onions will show this the most) have some areas that are “toasted” looking but not cooked to the mushy, soft stage.
Step 16 – Remove the cooked herb Bouquet and the bay leaves. We are about to “ordain” and garnish this pot of stew with the onions and the mushrooms; we don’t want to mess up our masterpiece by trying to fish-out the bay leaves and the herb Bouquet.
Step 17 – Open the stew pot and add the mushroom / pearl onion mixture to the top of the stew and let settle in. I don’t stir the mushrooms and pearl onions in. However, it’s perfectly A-OK to do so.
