Another reason to love chuck roast
Chuck roast is one of the most versatile and budget-friendly cuts of beef. When braised low and slow it becomes tender and shreddable, making it ideal for sandwiches, stews, and hearty dinners.
This recipe is perfect for making ahead: braise the beef, shred it, and keep it refrigerated to assemble quick sandwiches throughout the week. It pairs especially well with a creamy tomato or broccoli-cheddar soup for a comforting meal.
Recipe Ingredients
Below is a photo of the main ingredients and a short list of notes to help you choose the right components for this sandwich.

- Chuck roast: Use a 2 1/2 pound chuck roast cut into large chunks to make shredding easy.
- Stock: Low-sodium beef stock is preferred for braising so you can control the final seasoning.
- Bread: Soft bread such as a large Italian loaf, ciabatta, or soft rolls works best — it soaks up the juices and stays tender when you bite through the sandwich.
- Cheese: Mild American muenster melts beautifully; mozzarella or mild provolone are good alternatives.
- Barbecue sauce: The recipe includes a simple homemade sauce made from ketchup, brown sugar, honey, vinegar, and Worcestershire, but a favorite store-bought sauce can be used instead.

Units: US Customary (Metric equivalents may be used as desired).
Instructions
Make the barbecue sauce
- Combine the ketchup, vinegar, brown sugar, honey, and Worcestershire sauce in a saucepan. Bring to a gentle simmer, stirring frequently. Taste and adjust with salt and pepper. Remove from heat and set aside.
Braise the chuck roast and prepare the onions
- Preheat the oven to 300°F and arrange a rack to accommodate a large Dutch oven.
- Season the chuck roast pieces generously with salt and pepper on all sides.
- Heat a large Dutch oven over medium heat with 3 tablespoons olive oil. Sear the chuck roast pieces on all sides until browned, then transfer them to a plate.
- Add the beef stock to the pot, bring to a boil, and scrape up any browned bits from the bottom with a wooden spoon. Turn off the heat, stir in 1 cup of the prepared barbecue sauce, return the beef to the pot, and cover.
- Place the covered pot in the preheated oven and braise until the beef is fork-tender and easily shreds, about 3 hours. Oven times vary—continue cooking until shreddable.
- While the beef braises, toss the sliced onions with the cornstarch and let them sit for about 10 minutes so the coating adheres.
- Pour oil into a high-walled pan to about 1″ depth and heat to approximately 370°F (or until a piece of onion sizzles and crisps). Fry the onions in batches until golden brown and crisp. Use a slotted spoon to transfer them to a paper towel-lined tray to drain and season lightly with salt.
- When the beef is done, remove the pieces and place them in a bowl. Shred with two forks or your hands, then mix in 1/2 cup of the reserved braising liquid and 1/2 cup of the barbecue sauce to moisten and flavor the meat.
- Slice the loaf of bread open and place it on a baking sheet. Layer the shredded beef over the bottom half, top with slices of muenster cheese, and warm in the oven a few minutes to melt the cheese.
- Remove from the oven, spread a layer of barbecue sauce on the top half of the bread, add arugula, and sprinkle generously with the crispy onions. Close the sandwich, slice into portions, and serve immediately.
Notes
- Servings: Makes 4 large sandwiches or 6 smaller sandwiches.
- Bread choice: A softer bread is recommended so it soaks up juices and remains easy to bite through. Save crusty loaves for sandwiches where a firmer crust is preferred.
- Doneness: The 3-hour braise time is an estimate. Cook until the roast is fall-apart tender and easily shredded with a fork; if it’s not done at 3 hours, continue cooking and check periodically.
- Slow cooker option: You can braise the chuck roast in a slow cooker — expect about 8–9 hours on low or 4–5 hours on high until shreddable.
- Make-ahead and storage: Braised beef can be refrigerated for up to 3 days and reheats well. Crispy onions keep best in a sealed container for up to 3 days; re-crisp them briefly in the oven if needed. Leftover barbecue sauce will keep in the refrigerator for up to 2 weeks.
- Cheese substitutions: Use mozzarella or a mild provolone if you prefer a different melting cheese.

Top tips
- Make ahead: Braise the beef in advance and refrigerate. Reheat the shredded beef gently with a splash of braising liquid or barbecue sauce before assembling sandwiches.
- Check tenderness: Test the roast by shredding a piece; if it resists, return it to the oven and continue cooking until fork-tender.
- Frying onions: Fry in small batches to avoid overcrowding and maintain oil temperature for the crispiest onions.
- Serving: These sandwiches pair nicely with a simple green salad, a bowl of soup, or classic sides like coleslaw or potato chips.
