Learn how to make delicious Easy Slow Cooker French Onion Roast. Easy recipe with step-by-step instructions.

  • Total Time: 45 minutes
  • Yield: 4 servings 1x

Ingredients

Scale

  • 3 pounds (about 1.4 kg) beef chuck roast, trimmed of excess fat (substitute with pork shoulder or lamb shoulder if preferred)
  • 4 large onions, thinly sliced (yellow onions work best for sweetness)
  • 4 cloves garlic, minced
  • 2 tablespoons unsalted butter (or olive oil for a lighter option)
  • 1 cup beef broth (or vegetable broth for a lighter taste)
  • 1 cup dry white wine or dry sherry (optional, can substitute with extra broth)
  • 2 tablespoons Worcestershire sauce
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
  • 1 bay leaf
  • Salt and freshly ground black pepper, to taste
  • 2 tablespoons all-purpose flour (to thicken the sauce)
  • Fresh parsley, chopped, for garnish (optional)

Instructions

  1. Start by slicing your onions thinly. I remember my mum telling me that caramelising onions properly is the heart of any good French onion dish. In a large skillet or frying pan, melt the butter over medium heat.
  2. Add the onions and a pinch of salt to the pan. Cook slowly, stirring occasionally, until they turn a deep golden brown and become sweet and soft. This usually takes about 25 to 30 minutes. The smell will transport you straight back to my mum’s kitchen on a crisp Devon morning.
  3. Once the onions are beautifully caramelised, add the minced garlic and cook for another minute until fragrant.
  4. Sprinkle the flour over the onions and garlic, stirring well to coat. This will help thicken the sauce later on. Cook for an additional 2 minutes to remove the raw flour taste.
  5. Deglaze the pan with the white wine or sherry, scraping up any browned bits from the bottom. Let it simmer for 2 to 3 minutes so the alcohol cooks off and the liquid reduces slightly.
  6. Transfer the onion mixture to the slow cooker. Place the roast on top of the onions.
  7. Pour the beef broth and Worcestershire sauce over the roast. Sprinkle with thyme leaves, add the bay leaf, and season generously with salt and pepper.
  8. Cover and cook on low for 8 to 10 hours, or on high for about 4 to 5 hours. The meat should be fork-tender and infused with the rich onion sauce.
  9. Once cooked, remove the roast and let it rest for about 10 minutes before slicing. Meanwhile, give the sauce a good stir. If it’s too thin, you can thicken it by transferring it back to the pan and simmering gently, or stirring in a little more flour mixed with cold water.
  10. Slice the roast against the grain and spoon the luscious onion sauce over the top. Garnish with fresh parsley if you like a splash of colour and freshness.
