How to make French Onion Beef Stew with Cheesy Bread Topping

Making French Onion Beef Stew is straightforward and rewarding. Here’s a simple guide to crafting this delightful dish in your own kitchen.

Ingredients:

1 ½ lbs (680 g) beef chuck, cut into cubes
2 tsp coarse sea salt
1 tsp black pepper
2–3 tbsp olive oil (as needed)
2 tbsp unsalted butter
5 large onions, thinly sliced
1 tsp brown sugar
1 tbsp fresh thyme leaves
4 garlic cloves, minced
1 tbsp Worcestershire sauce
1 tbsp Dijon mustard
1 tbsp tomato paste (optional)
1 tbsp all-purpose flour
2 ½ cups (620 ml) beef broth or stock
2 bay leaves
1 white baguette, sliced
Olive oil (for brushing)
2 tbsp Dijon mustard
1 ½ cups (150 g) shredded Gruyère cheese
3 tbsp grated Parmesan cheese
½ tbsp fresh thyme, for garnish

Directions:

Prepare the Onions: Start by peeling the onions, keeping the root ends intact. This helps them stay together while slicing. Thinly slice the onions using a sharp knife or a mandoline. Keep tissues handy for any tears!
Brown the Beef: Pat the beef cubes dry and season them well with salt and pepper. Heat olive oil in a large Dutch oven over medium-high heat. Add the beef in batches, browning it on all sides. Once seared, remove the beef and set it aside.
Cook the Onions: Lower the heat to medium. Add butter to the same pot and let it melt. Add the sliced onions, brown sugar, and a pinch of salt. Cook for about 15 minutes, stirring occasionally, until the onions become soft and golden brown.
Combine Ingredients: After the onions are ready, add minced garlic and fresh thyme. Cook for an additional 5 minutes until fragrant. Sprinkle flour over the onions and stir for 1 minute. If using, add tomato paste, Dijon mustard, and Worcestershire sauce to the mix.
Add Broth and Beef: Gradually pour in the beef broth while stirring and scraping up any browned bits from the bottom of the pot. Return the browned beef to the pot and add bay leaves. Bring the mixture to a simmer.
Bake the Stew: Cover the pot and carefully transfer it to a preheated oven set at 320°F (160°C). Cook for roughly 1½ hours until the beef is tender and the sauce has thickened. Once done, discard the bay leaves and taste. Adjust the seasoning if necessary.
Prep the Cheesy Bread Topping: Preheat your oven to 375°F (190°C). Slice the baguette and brush both sides of each slice with olive oil. Arrange them on a baking tray and toast for about 15 minutes, flipping halfway through, until they are golden and crisp.
Assemble the Stew: Spread each toasted baguette slice with Dijon mustard. Top them with a mix of shredded Gruyère cheese and grated Parmesan cheese. Ladle the hot stew into ovenproof bowls and arrange the cheesy toasts on top.
Broil for Perfection: Place the assembled bowls in the oven and broil for 2-3 minutes until the cheese melts and turns a lovely golden brown.
Garnish and Serve: Finish the stew with a sprinkle of fresh thyme and any reserved caramelized onions. Serve hot, and enjoy the amazing mix of flavors and textures!
