Cook the lardons in the casserole for 4 minutes without added fat, then set them aside. Add 1 tablespoon of neutral oil and sear the beef in batches for 2–3 minutes on each of two sides.
Keep the cubes in one layer and let the casserole regain its heat between batches.
Set the beef aside with the lardons and keep the browned bits in the casserole.
Look for this: Each batch has a brown crust and no liquid is pooling in the casserole.
Lower to medium heat and cook the carrots and pearl onions for 5 minutes, then add the chopped garlic for 30 seconds. Stir in 2 tablespoons of flour for 1 minute, then add the wine and stock while scraping the base.
Return the beef and lardons, add the bouquet garni, remaining salt and pepper; the liquid should almost cover the cubes.
Wait for a gentle simmer before moving to the next step.
Look for this: The sauce is smooth and every browned bit has lifted from the casserole base.
Simmer
2 hr 30 then 15 min rest
Braise until tender
2 hr 30 then 15 min restvery low heat; mushrooms over medium-high heat
Cover and simmer the beef over very low heat, stirring every 45 minutes. After 1 hour 55 minutes, quarter the mushrooms and brown them in a dry frying pan over medium-high heat for 6–8 minutes. Once the beef has simmered for 2 hours 5 minutes, stir in the browned mushrooms and simmer for 25 more minutes, for a total of 2 hours 30 minutes.
Keep only a few small bubbles rising at a time; vigorous boiling will toughen the beef.
After the full 2 hours 30 minutes of simmering, take the casserole off the heat and rest it, covered, for 15 minutes before serving.
Look for this: The beef pulls apart under a fork without feeling dry, and the mushrooms are browned rather than watery.
Storage and reheating
Refrigerator
Keep in the fridge for up to 3 days; the flavour often improves after a night.

Freeze for up to 3 months without a potato garnish.
Reheating
Reheat very gently, covered, until the sauce is simmering evenly and the beef is piping hot.
