In a large dutch oven or heavy based pot, sauté the bacon over medium heat in 1 tablespoon of oil 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 and return the bacon and beef back into the pot; season with 1/2 teaspoon coarse salt and 1/4 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, bullion and herbs. Cover and bring to a boil, then reduce heat to low and simmer for 1 1/2 to 2 hours, stirring occasionally, until the meat is falling apart.

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.

Add browned mushrooms to the pot, let simmer for an additional 3 to 5 minutes, stirring occasionally, to combine.

Garnish with parsley and serve with mashed potatoes, rice or noodles.
