Ingredients

For this Classic French Onion Pot Roast, you’ll need well-marbled beef and plenty of onions for maximum flavor.

3 lb chuck roast (1.4 kg), boneless, for tenderness
2 tbsp olive oil (30 ml), for searing
4 large yellow onions, thinly sliced
4 cloves garlic, minced
2 cups beef broth (480 ml), low sodium preferred
1 cup dry beef broth or stock concentrate (240 ml equivalent)
2 tbsp Worcestershire sauce (30 ml)
2 tbsp all-purpose flour (16 g), for thickening
1 tsp salt (5 g), adjust to taste
1 tsp black pepper (2 g), freshly ground
2 sprigs fresh thyme or 1 tsp dried thyme

Each ingredient plays a role in building the signature flavor of Classic French Onion Pot Roast.

Pro Tips

Pat the chuck roast completely dry before seasoning. This step ensures a deep, flavorful sear that locks in juices. Take your time caramelizing the onions; low heat and patience bring out their natural sweetness, which defines the dish. Deglaze the pot thoroughly after searing to capture every browned bit, as those bits enrich the sauce. Finally, keep the roast mostly submerged but not drowned, so it braises instead of boiling. These techniques elevate your Classic French Onion Pot Roast from good to unforgettable.

Instructions

Step 1
Season the chuck roast generously with salt and black pepper on all sides. Heat olive oil in a large Dutch oven over medium-high heat.

Step 2
Sear the roast for 4 to 5 minutes per side until a deep brown crust forms. Remove the beef and set it aside.

Step 3
Reduce heat to medium and add sliced onions to the same pot. Cook slowly, stirring often, until they turn golden and caramelized, about 20 minutes.

Step 4
Stir in minced garlic and cook for 30 seconds until fragrant. Sprinkle flour over the onions and stir to coat evenly.

Step 5
Deglaze with beef broth, scraping up browned bits from the bottom. Add Worcestershire sauce and thyme.

Step 6
Return the roast to the pot, nestling it into the onion mixture. Spoon some onions over the top.

Step 7
Cover and cook on low heat for 3 to 3.5 hours, or until the beef becomes fork-tender.

Step 8
Taste the sauce and adjust seasoning. Serve hot with onions and gravy spooned generously over the beef.

Variations

Transform this Classic French Onion Pot Roast with easy adaptations. For a slow cooker onion pot roast, follow the same searing steps, then transfer everything to a slow cooker and cook on low for 8 hours. For a French onion beef roast with mushrooms, add 8 oz sliced mushrooms during onion cooking. For a lighter version, use leaner beef and reduce onions slightly while maintaining flavor depth.

Storage and Serving

Store leftover Classic French Onion Pot Roast in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop to preserve tenderness. Serve over mashed potatoes, buttered egg noodles, or crusty bread to soak up the sauce. It also pairs beautifully with roasted vegetables or a simple green salad.
