Beef slowly braised in dry red wine, with caramelized onions, fennel and a touch of rhubarb, without flour or starch.
Marbled beef turns tender over several hours in dry red wine, while the onions brown and thyme, sage and a touch of fennel infuse the Dutch oven with their aromas. Rhubarb adds a bright acidity at the end of cooking. For two servings, allow 15 minutes of preparation and around 4 hours 30 minutes of cooking, for a sauce that coats the back of a spoon without flour or starch. One to file alongside my keto main dishes.
What is slow-braised beef in red wine?
Braising means cooking slowly over steady heat, with the lid on. In beef braised in red wine, the wine is the main braising liquid: it simmers just enough to tenderize the meat and concentrate the juices.
During this long cooking process, collagen gradually turns into gelatin. The juices thicken enough to coat the back of a spoon without flour or starch, keeping the dish low in carbohydrates.

The tradition of dishes braised in red wine
Dishes braised in red wine are part of French home cooking. They call for slow cooking, controlled heat and a cut of meat that becomes tender rather than drying out.
This version keeps the spirit of a classic wine-braised dish, with a more pronounced aromatic profile: fennel brings an anise note, rhubarb adds acidity, and paprika and sage give the sauce more character. Fresh rhubarb is mainly available in spring and early summer, and only its stalks are used in cooking.
The main ingredients
Two generous, well-marbled pieces of chuck or braising beef stand up to the long cooking time and release the gelatin that thickens the sauce. A cut that is too lean would lose tenderness. Two sliced red onions, sautéed and then caramelized over low heat, balance the acidity of the wine, balsamic vinegar and rhubarb.

The fennel, thinly sliced and added about an hour before the end, becomes tender without falling apart. Four rhubarb stalks bring a fruity acidity to the cooking juices, balancing the richness of the wine and beef. For seasoning, use two teaspoons of paprika for gentle warmth and color, two of dried thyme, one of dried sage and one of fennel seeds ground in a mortar.
The red wine, half a small bottle, preferably dry, serves as the braising liquid and loosens the browned bits stuck to the Dutch oven. A splash of balsamic vinegar adds depth. For cooking, avocado oil, mild olive oil or high-oleic sunflower oil stands up to the heat; butter, especially from grass-fed cows, adds color and a creamy richness.

Cooking tips and serving suggestions
Let the chuck steaks come to room temperature, then sear them to brown the meat without burning it, pushing the onions to one side of the Dutch oven. Cooking the onions slowly for 15 to 30 minutes matters just as much as the braising: it gives the sauce its sweetness. Pour in the wine to deglaze, almost covering the meat, add a splash of vinegar, then cover and cook at the gentlest simmer, keeping an eye on the liquid level.

The total time is around 4 hours 30 minutes, with at least 3 hours of simmering: go by the texture, a fork should slide in without resistance and the fibers should pull apart. The fennel goes into the Dutch oven an hour before the end, and the rhubarb only 10 to 15 minutes before serving, so it does not fall apart. To keep the meal low in carbohydrates, serve with cauliflower mash, air fryer zucchini or green vegetables such as stir-fried bok choy.
