Traditional Oven Method

• Preheat oven to 350°F (175°C).
• Heat the oil in a large dutch oven or heavy based pot. Sauté the bacon over medium heat for about 3 minutes, until crisp and browned. Transfer with a slotted spoon to a large dish and set aside.
• Pat dry beef with paper towel; sear in batches in the hot oil/bacon fat until browned on all sides. Remove to the dish with the bacon.
• In the remaining oil/bacon fat, sauté the carrots and diced onions until softened (about 3 minutes), then add 4 cloves minced garlic and cook for 1 minute. Drain excess fat (leave about 1 tablespoon in the pan) and return the bacon and beef back into the pot; season with ½ teaspoon coarse salt and ¼ teaspoon ground pepper. Sprinkle with flour, toss well and cook for 4-5 minutes to brown.
• Add the pearl onions, wine, and enough stock so that the meat is barely covered. Then add the tomato paste, bouillon, and herbs. Bring to a simmer on the stove.
• Cover, transfer to the lower part of the oven and simmer for 2 to 3 hours, or until the meat is fall apart tender (adjust the heat so that the liquid simmers very slowly).
• In the last 5 minutes of cooking time, prepare your mushrooms: Heat the butter in a medium-sized skillet/pan over heat. When the foam subsides, add the remaining 2 cloves garlic and cook until fragrant (about 30 seconds), then add in the mushrooms. Cook for about 5 minutes, while shaking the pan occasionally to coat with the butter. Season with salt and pepper, if desired. Once they are browned, set aside.
• Place a colander over a large pot. Remove the casserole from the oven and carefully empty its contents into the colander (you want to collect the sauce only). Discard the herbs.
• Return the beef mixture back into the dutch oven or pot. Add the mushrooms over the meat.
• Remove any fat off the sauce(if any) and simmer for a minute or two, skimming off any additional fat which rises to the surface.
• You should be left with about 2 ½ cups of sauce thick enough to coat the back of a spoon lightly. If the sauce is too thick, add a few tablespoons of stock. If the sauce is too thin, boil it over medium heat for about 10 minutes, or until reduced to the right consistency.
• Taste for seasoning and adjust salt and pepper, if desired. Pour the sauce over the meat and vegetables.
• If you are serving immediately, simmer the beef bourguignon for 2 to 3 minutes to heat through. Garnish with parsley and serve with mashed potatoes, rice, or noodles.
• To serve the following day, allow the casserole to cool completely, cover and refrigerate. The day of serving, remove from refrigerator for at least an hour before reheating. Place over medium-low heat and let simmer gently for about 10 minutes, basting the meat and vegetables with the sauce.
