Belgian Recipes for Dinner: Flemish Beef Stew Recipe

Carbonnade flamande is a Belgian Flemish beef stew braised with onions and dark beer until the meat is tender and the sauce is rich and gently sweet-sour. A slice of mustard-spread bread thickens the gravy as it simmers, making this a comforting dinner that pairs naturally with fries, potatoes, or crusty bread.

Ingredients

3 lb (1.36 kg) beef chuck, cut into 1½-inch (4 cm) cubes
1 tsp (6 g) fine salt, plus more to taste
½ tsp (1 g) black pepper, plus more to taste
2 tbsp (30 ml) neutral oil, such as canola
2 tbsp (28 g) unsalted butter
5 medium yellow onions, about 6 cups (900 g), thinly sliced
2 tbsp (16 g) all-purpose flour
1 bottle Belgian dark ale, 11.2 fl oz (330 ml); choose a malty, not strongly bitter beer
1½ cups (360 ml) beef stock, preferably low-sodium
2 tbsp (30 ml) apple cider vinegar
2 tsp (8 g) packed brown sugar
2 bay leaves
4 fresh thyme sprigs, or 1 tsp (1 g) dried thyme
1 slice firm country bread or rye bread, about 1 oz (28 g)
1 tbsp (15 g) Dijon mustard
2 tbsp (8 g) chopped fresh parsley, optional, for serving

Instructions

Prepare the beef and onions, 30 minutes. Pat the beef cubes dry with paper towels; dry surfaces brown more effectively than damp ones. Season them all over with the salt and pepper. Peel and thinly slice the onions, measure the remaining ingredients, and set out a heavy Dutch oven or other large, heavy-based pot with a lid. Keeping the cubes close to the same size helps them become tender at roughly the same time.
Brown the beef, about 15 minutes. Heat the oil in the pot over medium-high heat until it shimmers. Brown the beef in batches, turning the cubes so several sides develop a deep brown crust. Avoid crowding the pot: meat packed tightly together releases moisture and steams instead of browning. Transfer each browned batch to a plate. If the pot looks dry between batches, add a small splash of oil rather than letting the browned bits scorch.
Soften the onions, about 12 minutes. Reduce the heat to medium and add the butter and sliced onions. Stir often, scraping up the browned fond on the bottom of the pot as the onions release moisture. Cook until the onions are soft and golden at the edges, not deeply crisped. Sprinkle in the flour and stir for about 1 minute so it coats the onions and loses its raw taste.
Build the braising liquid, about 8 minutes. Pour in the beer gradually, scraping the base of the pot to loosen any browned bits. Add the stock, vinegar, brown sugar, bay leaves, and thyme, then return the beef and any juices on the plate to the pot. Bring the liquid to a gentle simmer. Spread the mustard over one side of the bread and place it mustard-side down on top of the stew; it will gradually dissolve and help thicken the sauce. If the bread is very crusty, tear it into a few pieces first.
Braise until tender, 2 hours 2 minutes. Cover the pot, reduce the heat to low, and keep the stew at a very gentle simmer for 2 hours and 2 minutes. Check occasionally that it is not boiling hard or sticking; stir carefully once or twice, keeping the beef mostly submerged. If the liquid is bubbling vigorously, lower the heat. The beef should be easy to pierce with a fork. Tough cubes need more time, so continue simmering in 15-minute increments if necessary.
Thicken and finish, about 8 minutes. Remove the lid and simmer gently for about 8 minutes, stirring once or twice, until the sauce clings lightly to the beef. Take a large cube from the stew and check its center with a food thermometer: USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of beef; this long braise should make the meat tender as well. Rest the checked piece for 3 minutes before tasting. Remove the bay leaves and thyme stems, then taste the sauce and adjust salt, pepper, or vinegar to balance it. Serve hot, with parsley if you like.

Tips

Choose the beer for its malt, not its strength. A dark Belgian ale gives the stew its characteristic roasted, malty depth. Very hoppy or sharply bitter beers can make the sauce taste harsh after a long simmer. If Belgian ale is unavailable, use another malty brown or amber ale. For an alcohol-free option, use extra beef stock with 1 tablespoon (15 ml) additional cider vinegar; the result is less malty but still savory.
Keep the simmer gentle. A hard boil can make the meat tighten and the sauce reduce too quickly before the beef softens. A few lazy bubbles are enough. If the sauce becomes too thick while the beef is still firm, stir in stock or water a few tablespoons at a time.
Balance the sauce at the end. Beer, onions, and sugar bring sweetness, while vinegar provides contrast. Taste only after the stew has reduced, then add vinegar in small amounts if it tastes heavy or sweet. If it seems too sharp, simmer a little longer or add a small splash of stock rather than adding more sugar immediately.
Use a suitable pot and cut. A heavy Dutch oven holds steady heat, and chuck has enough connective tissue to become succulent during a long braise. Lean steak cuts may cook faster but are more likely to turn dry or firm. If using a slow cooker, brown the beef and onions first; the texture and sauce reduction will differ, so reduce the stock and finish the sauce on the stove if it is thin.

Serving Suggestions

Serve carbonnade flamande in warm shallow bowls with Belgian-style fries, often called frites, so they can be dipped into the gravy. Mashed potatoes, boiled baby potatoes, or buttered egg noodles are practical alternatives that also catch the sauce. A slice of crusty bread is useful for wiping the bowl clean, especially if you want a simple dinner without another starch on the side.

To balance the rich stew, add a crisp green salad dressed with a sharp vinaigrette, or serve a vegetable such as green beans, roasted carrots, or braised endive. Keep extra salt off the table until the stew is tasted, since stock and beer brands vary in saltiness. If serving family-style, bring the pot to the table and offer the fries or potatoes separately so they stay crisp.

Variations

There are regional and household variations of this Flemish dish; no single version represents every Belgian cook. Some cooks use a spoonful of mustard directly in the sauce, while others rely on the mustard bread. For a more pronounced tang, spread 2 teaspoons (10 g) extra Dijon on the bread. For a milder flavor, use country bread and reduce the vinegar to 1 tablespoon (15 ml), then adjust after the stew cooks.

If you cannot find Belgian dark ale, a malty brown ale or amber ale is a useful substitute, though the flavor will be less specifically Belgian. Traditional recipes may use a slice of pain d’épices, a spiced sweet bread, in place of plain bread. It can be hard to find; use country bread with the measured brown sugar and a small pinch of ground cinnamon instead, understanding that this gives a simpler, less aromatic sweetness. For a gluten-free version, omit the flour and bread, then thicken the finished sauce with a cornstarch slurry made from 1 tablespoon (8 g) cornstarch and 1 tablespoon (15 ml) cold water. Stir it in and simmer until glossy.

You can also add 8 oz (225 g) sliced mushrooms with the onions for an earthier stew. They release moisture, so cook them until that liquid has mostly evaporated before adding the flour. For a slightly lighter sauce, replace up to half of the beef stock with water, but avoid removing all the stock because it contributes savory depth.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking in a covered, shallow container. The stew keeps for 3 to 4 days in the refrigerator. Its flavor often becomes more rounded by the next day, and the sauce may thicken as it chills. If it seems gelled or very thick when cold, that is normal; it loosens as it warms.

For longer storage, freeze the cooled stew in meal-size airtight containers for up to 3 months for best quality. Thaw it overnight in the refrigerator, not on the counter. Reheat on the stove over low to medium-low heat, stirring occasionally and adding a splash of stock or water if needed. Heat leftovers to 165°F (74°C), checking the center with a food thermometer. You can also microwave individual portions in a covered, microwave-safe dish, stirring partway through so the heat spreads evenly.

Frequently Asked Questions

What is carbonnade flamande?
It is a Flemish Belgian beef-and-onion stew braised with beer. The beer, onions, and mustard bread create a deep, savory sauce with a gently sweet and tangy finish. Recipes vary by region and household, particularly in the choice of beer and bread.

Does the alcohol cook out of the stew?
Some alcohol evaporates during cooking, but a long simmer does not guarantee that every trace is gone. If you need to avoid alcohol, use extra beef stock and a little more cider vinegar instead of beer. The flavor will be less malty, but the stew will still be satisfying.

Can I make this stew a day ahead?
Yes. Cool it promptly, refrigerate it within 2 hours, and reheat it the next day to 165°F (74°C). The sauce may thicken overnight, so add a little stock or water as it warms. Keep fries or other crisp accompaniments separate until serving.

Why is my beef still tough after two hours?
Beef chuck can vary in size and tenderness, and a strong simmer or crowded pot can affect how it cooks. Keep the pot covered at a gentle simmer and continue cooking in 15-minute increments until a fork slips into the cubes easily. Add a little liquid if the sauce is reducing too quickly.

What can I use instead of mustard bread?
Use a small piece of plain country or rye bread and spread it with Dijon mustard as directed. For a gluten-free stew, omit the bread and flour and thicken the sauce with a cornstarch slurry at the end. The texture will be smooth rather than having the traditional bread-thickened body.

Can I make carbonnade in a slow cooker?
Yes, but brown the beef and soften the onions in a skillet first for better flavor. Transfer them to the slow cooker with the other ingredients and cook on low until the beef is fork-tender, usually about 7 to 8 hours depending on the appliance. Use less stock because a slow cooker loses little moisture, and thicken the sauce on the stove if it needs it.
