Tools & Equipment Needed

• Large Dutch oven or heavy-bottomed pot
• Skillet or frying pan
• Baking tray for toasting bread
• Ovenproof bowls or ramekins
• Wooden spoon or spatula
• Sharp knife or mandoline
• Measuring spoons and cups
• Whisk
• Aluminum foil

Step-by-Step Instructions

1. Prepare the Onions

• Peel the onions and cut off the tops, keeping the root ends intact. This helps hold the slices together during cooking.
• Slice thinly using a sharp knife or mandoline. Keep a tissue handy — onion fumes can sting the eyes!

2. Sear the Beef

• Pat beef cubes dry with paper towels to ensure proper browning.
• Season generously with sea salt and black pepper.
• Heat 2–3 tbsp olive oil in a Dutch oven over medium-high heat.
• Sear the beef in batches until all sides are browned. Avoid overcrowding the pan.
• Remove beef and set aside.

Browning the meat creates a deep, savory base and enhances the stew’s flavor.

3. Caramelize the Onions

• Reduce heat to medium, melt 2 tbsp butter in the pot.
• Add sliced onions, brown sugar, and a pinch of salt.
• Cook for about 15 minutes, stirring occasionally, until onions turn golden and soft.
• Add garlic and thyme, cooking another 5 minutes until fragrant.

This step is critical — caramelized onions bring sweetness and complexity to the stew.

4. Build the Stew

• Sprinkle flour over the onions, stirring for 1 minute to remove the raw taste.
• Add tomato paste (optional), Dijon mustard, and Worcestershire sauce.
• Gradually pour in beef broth, stirring constantly and scraping up browned bits from the pan.
• Return seared beef to the pot, add bay leaves, and bring to a gentle simmer.

5. Slow Cook

• Cover the Dutch oven and transfer to a preheated oven at 320°F (160°C).
• Cook for 1½ hours, or until beef is tender and sauce thickens.
• Discard bay leaves and adjust seasoning as needed.

Slow cooking allows flavors to meld and the beef to become melt-in-your-mouth tender.

6. Prepare the Bread

• Preheat oven to 375°F (190°C).
• Slice the baguette and brush each slice with olive oil.
• Arrange on a baking tray and toast for 15 minutes, flipping halfway, until golden brown.

This step creates the perfect base for the cheesy topping — crispy yet soft enough to soak up the stew.

7. Assemble and Broil

• Spread each toasted slice with a thin layer of Dijon mustard.
• Top with a mixture of shredded Gruyère and Parmesan.
• Ladle hot beef stew into ovenproof bowls and place cheesy toasts on top to cover.
• Broil for 2–3 minutes until cheese melts and turns golden brown.

8. Garnish and Serve

• Sprinkle with fresh thyme and a few reserved caramelized onions for an elegant finish.
• Serve immediately, enjoying the rich flavors and the gooey, crunchy topping.

Tips & Variations

• Extra richness: Add a splash of beef stock while reheating leftovers.
• Air fryer bread: Toast baguette slices at 350°F (180°C) for 8–10 minutes for a quicker method.
• Cheese alternatives: Swap Gruyère for Swiss or fontina, or use a blend for different flavors.
• Side serving option: Serve cheesy bread separately for a lighter presentation.
• Vegetable additions: Add diced carrots or mushrooms to the stew for more depth and texture.
