Ingredients for French Onion Beef Stew
To bring this savory mashup to life, you’ll need:
- 2.5–3 lbs beef chuck or braising steak, cut into cubes
- Salt & pepper, to season
- 2 tablespoons olive oil + 2 tablespoons butter
- 4–5 large onions, thinly sliced
- 1 teaspoon sugar (optional, to aid caramelization)
- 4 cloves garlic, minced
- 1 cup dry Marsala, white wine, or sherry
- 2 tablespoons Dijon mustard
- 1 tablespoon Worcestershire sauce
- 1 tablespoon flour
- 4 cups beef broth (use high-quality stock for best flavor)
- 2 bay leaves + 3–4 sprigs fresh thyme

How to Make French Onion Beef Stew
1. Caramelize the onions
Melt butter in a large Dutch oven over medium-high heat. Add sliced onions, a generous pinch of salt, and optional sugar. Cook, stirring frequently, until deep golden brown—about 30 minutes. Stir in garlic and cook 1–2 minutes longer. Reserve a few tablespoons of onions for garnish.
2. Brown the beef
Season the beef cubes generously with salt and pepper. In batches, sear them in olive oil until nicely browned on all sides. Do not overcrowd the pan. Transfer beef to a plate and set aside.
3. Deglaze the pan
Pour in the Marsala or wine to deglaze the pan. Scrape up all the browned bits (the fond) with a wooden spoon. Let the wine simmer for 3–5 minutes to reduce slightly.
4. Build the stew
Stir in the Dijon mustard, Worcestershire sauce, and flour. Slowly add the beef broth while stirring to prevent lumps. Return the browned beef (and any juices) to the pot. Add bay leaves and thyme. Bring to a simmer.
5. Bake the stew
Preheat oven to 320°F (160°C). Cover the Dutch oven and bake for 1.5 to 2 hours, or until the beef is fork-tender.
6. Prepare the cheesy bread
Toast the baguette slices at 375°F (190°C) until golden, about 10–15 minutes. Top with Dijon (optional), then pile on Gruyère and Parmesan.
7. Assemble and broil
Ladle the French Onion Beef Stew into oven-safe bowls. Top each with a cheesy bread slice and broil until the cheese is bubbling and golden. Garnish with reserved onions and a sprinkle of fresh thyme.
Tips for Perfect French Onion Beef Stew
- Don’t rush the onions: Deep caramelization adds incredible depth—be patient.
- Sear in batches: Crowding the pan leads to steaming, not browning.
- Use quality cheese: Gruyère and Parmesan melt beautifully and bring nutty, salty contrast.
- Make ahead: The stew tastes even better the next day. Just add the bread topping before serving.
- Fan-forced oven? Lower the temperature by 15–20°F to avoid overcooking.
Storage & Reheating
- Refrigerate leftover stew (without bread topping) in an airtight container for up to 3 days.
- Freeze stew for up to 3 months. Thaw in the fridge before reheating.
- Reheat gently on the stove or in the oven. Add fresh cheesy bread topping just before serving.
Serving Suggestions
- Serve with a green salad dressed in Dijon vinaigrette.
- Pair with a glass of dry red or white wine like Pinot Noir or Sauvignon Blanc.
- Offer additional toasted cheesy baguette slices on the side for dipping.
