Ingredients

Here’s what you’ll need to create this masterpiece:

For the Beef:

• 900 g of bavette de bœuf or paleron, sliced into portions
• 2-3 tablespoons olive oil
• 450 ml beef broth
• 4 large onions, thinly sliced
• 50 g unsalted butter
• 4 garlic cloves, minced
• 2 tablespoons brown sugar
• 1 tablespoon fresh thyme, chopped (plus extra for garnish)
• 2 tablespoons all-purpose flour
• 300 ml additional beef broth (if needed)
• 2 bay leaves

For the Crust:

• 1 pre-baked baguette
• 2 tablespoons olive oil
• 2 large eggs, beaten
• 1 tablespoon Dijon mustard
• 3 tablespoons heavy cream
• 175 g grated Gruyère cheese

Substitution Options

Don’t stress if you’re missing an ingredient! Here are some swaps:

• Use chuck roast instead of bavette or paleron.
• Swap Gruyère for Comté or Parmesan if needed.
• Replace heavy cream with sour cream or crème fraîche.
• If you don’t have fresh thyme, dried thyme works fine (use half the amount).

Preparation Section

Let’s dive into the steps! Follow along, and soon you’ll have a bubbling pot of deliciousness ready to serve.

Step 1: Sear the Beef

Start by seasoning your beef generously with salt and pepper. Heat a tablespoon of olive oil in a large Dutch oven over medium-high heat. Add half of the beef slices and sear them for about 2 minutes per side until golden brown. Remove and set aside. Deglaze the pan with a splash of beef broth, scraping up any browned bits, then pour this liquid over the reserved beef. Repeat with the remaining beef. Pro tip: Don’t overcrowd the pan—this ensures a good sear.

Step 2: Caramelize the Onions

In the same pot, melt the butter and add the sliced onions with a pinch of salt. Cook them over medium heat for 8-10 minutes until they start to soften and turn golden. Stir in the garlic, brown sugar, and thyme, then lower the heat. Let the onions caramelize slowly for 30 minutes, stirring occasionally. They should be soft, sticky, and deeply golden. Chef’s tip: Patience is key here—the slower you cook, the sweeter they’ll taste.

Step 3: Prepare the Croûtes

Preheat your oven to 190°C (170°C fan). Slice the baguette into thick rounds, brush both sides with olive oil, and season lightly. Bake for 20 minutes, flipping halfway through, until crisp. Lower the oven temperature to 140°C (120°C fan) once done. These crunchy croûtes will form the base of our cheesy topping.

Step 4: Make the Sauce and Braise the Beef

Set aside a spoonful of caramelized onions for garnish. Stir the flour into the remaining onions and cook for a minute. Pour in the wine (optional) and let it simmer briefly before adding the beef broth, bay leaves, and reserved beef. Bring everything to a boil, cover, and transfer to the oven. Braise for 2 hours, allowing the flavors to meld and the meat to become fork-tender.

Step 5: Assemble and Finish

Mix the beaten eggs, mustard, cream, and Gruyère in a bowl. Spread this mixture onto the toasted croûtes. Arrange them on top of the beef, overlapping slightly. Increase the oven temperature to 200°C (180°C fan) and bake for 20 minutes until golden and bubbly. Garnish with reserved onions and fresh thyme before serving.

Timing

This recipe requires a bit of patience, but trust me—it’s worth it!

• Prep time: 30 minutes
• Cooking time: 3 hours
• Total time: 3 hours 30 minutes

Chef’s Secret

To elevate the flavor, deglaze the pot with a splash of red wine after searing the beef. The acidity brightens the dish and adds depth to the sauce.

Extra Info

Did you know that caramelizing onions takes longer than most people think? Many recipes claim it can be done in 10 minutes, but true caramelization requires low, slow heat to break down the sugars naturally. Trust the process!

Necessary Equipment

You’ll need:

• A large Dutch oven or heavy-bottomed pot
• A sharp knife for slicing onions and beef
• A baking sheet for toasting croûtes
• A whisk for mixing the egg and cheese topping

Storage

Leftovers? Lucky you! Store the beef and sauce separately from the croûtes to keep the latter crispy. Refrigerate in airtight containers for up to 3 days. Reheat gently on the stovetop or in the microwave. For longer storage, freeze the beef mixture for up to 3 months. Thaw overnight in the fridge before reheating.

If you want to re-crisp the croûtes, pop them back in the oven for 5 minutes at 180°C (160°C fan).

Finally, avoid freezing the assembled dish as the texture may suffer. Instead, prep components ahead and assemble just before baking.

Tips and Advice

– Use high-quality beef for the best results.
– Taste as you go—adjust seasoning as needed.
– If the sauce thickens too much, thin it out with a little broth.
– Serve with mashed potatoes or roasted veggies for a complete meal.

Presentation Tips

Sprinkle extra thyme leaves on top for a pop of color. Serve in individual ramekins for a rustic touch, or present the entire dish family-style for a cozy vibe.

Healthier Alternatives

Want to lighten things up? Try these variations:

1. Leaner Protein: Substitute beef with chicken thighs or turkey breast.
2. Low-Carb Option: Skip the croûtes and sprinkle the cheese directly on the beef.
3. Veggie-Packed Version: Add mushrooms or carrots to the braise.
4. Dairy-Free Twist: Swap Gruyère for a plant-based cheese alternative.
5. Gluten-Free Friendly: Use gluten-free flour for thickening the sauce.
6. Herbaceous Boost: Add rosemary or sage for a different flavor profile.

Common Mistakes to Avoid

Mistake 1: Rushing the Onions

Caramelizing onions isn’t a quick task. Cooking them too fast can lead to burnt edges rather than sweet, golden goodness. Keep the heat low and stir often for the best results.

Mistake 2: Overcrowding the Pan

When searing the beef, resist the urge to cram everything in at once. Overcrowding causes steaming instead of browning, which means less flavor. Work in batches for a proper sear.

Mistake 3: Skipping the Resting Step

After braising, let the dish rest for 10 minutes before serving. This allows the flavors to settle and the sauce to thicken slightly. Patience pays off!

FAQ

Can I use a slow cooker?

Absolutely! After searing the beef and caramelizing the onions, transfer everything to a slow cooker and cook on low for 6-8 hours.

What type of wine should I use?

A dry red wine like Cabernet Sauvignon or Merlot works beautifully. Avoid anything too sweet or oaky.

Can I make this ahead?

Yes! Prepare the beef and sauce a day in advance, then refrigerate. Assemble and bake just before serving for maximum freshness.

Is this dish gluten-free?

Not entirely, due to the flour used in the sauce. However, you can substitute cornstarch mixed with water for thickening.

How do I prevent the croûtes from getting soggy?

Keep the croûtes separate from the beef until the last minute. Assemble right before baking to maintain their crunch.

Can I double the recipe?

Definitely! Just ensure your pot is large enough to accommodate the increased volume. Adjust cooking times slightly if needed.

What’s the best way to reheat leftovers?

Reheat gently on the stovetop or in the microwave. Add a splash of broth to keep the sauce moist.

Can I skip the wine?

Yes, though it adds depth. Simply replace it with additional beef broth.

What side dishes pair well?

Mashed potatoes, roasted vegetables, or a simple green salad complement the richness of the dish perfectly.

How do I know when the beef is tender?

The meat should easily pull apart with a fork. If it feels tough, give it more time in the oven.
