Ingredients :

• Braising beef — chuck roast or shank — Get chuck roast if you can find it. It’s the cut with the most collagen — the one that gives that melt-in-the-mouth texture you can’t get from a lean cut. Cut into about 4 cm cubes. Don’t look for something too clean or trimmed: a bit of fat and connective tissue is what will feed the sauce.
• Cremini mushrooms — These are just brown button mushrooms, more flavorful than the classic white ones. If you can’t find them, white ones work just fine. Don’t chop them too thin — in quarters, they keep their body after the long cook and don’t completely melt into the sauce.
• Dry onion soup mix — Lipton is the gold standard, but any brand will do. This packet replaces chopped onion, garlic, salt, and spices in a single step. It’s the real engine of the recipe — don’t underestimate it.
• Beef broth — Just half a cup. The goal isn’t to drown the meat but to prime the sauce. A good boxed broth or a bouillon cube dissolved in hot water. The meat will release its own juices during the hours of cooking — there’s much more than you’d think.
