Ingredients

  

Main Ingredients

• 3–4 lb chuck roast well-marbled is best
• 4 large yellow onions, thinly sliced for deep caramel flavor
• 3 cloves garlic, smashed
• 2 cups beef broth low sodium helps control salt
• 1 cup dry red wine or additional broth optional
• 2 tbsp Worcestershire sauce adds umami
• 2 tbsp tomato paste for richness, optional
• 2 tsp salt plus extra to taste
• 1 tsp black pepper
• 2 tbsp olive oil or vegetable oil for searing
• 2 sprigs fresh thyme or 1 tsp dried thyme
• 2 tbsp butter helps caramelize onions
• 1–2 tbsp cornstarch mixed with cold water optional, for thickening sauce

Method

 

Preparation

1. Heat 1 tbsp oil and 1 tbsp butter in the Dutch oven over medium heat. Add onions and a pinch of salt. Cook, stirring often, until deep golden brown and sweet, about 30-40 minutes. Reduce heat if they brown too quickly.

Searing the Roast

1. Pat roast dry and season with salt and pepper. Heat remaining oil over medium-high heat. Sear roast on all sides until deeply browned, 3-4 minutes per side. Remove roast and set aside.

Braising Liquid

1. Add garlic to the pot for 30 seconds, then stir in tomato paste. Deglaze with wine or a cup of broth, scraping up browned bits. Add remaining broth, Worcestershire, thyme, and bay leaf. Return onions to pot.

Braising

1. Nestle the seared roast into the onion mixture. Bring to a simmer, cover, and transfer to a 300°F oven. Cook 3-4 hours until fork-tender.

Finishing the Sauce

1. Remove roast and tent with foil. Skim excess fat from sauce. For a thicker gravy, simmer on stovetop and add cornstarch slurry until desired thickness. Adjust salt and pepper.

Serving

1. Slice or shred roast and spoon rich onion gravy over the top. Garnish with fresh thyme if desired.

Notes

Brown the onions low and slow for best sweetness; high heat gives bitter bits. Don’t skip searing the roast; browning adds crucial flavor. Leftover roast slices reheat better with a splash of broth to keep moist. Refrigerate cooled leftovers in an airtight container for up to 4 days.

3. Build the braising liquid

Pro Tips & Troubleshooting

• Brown the onions low and slow for best sweetness; high heat gives bitter bits.
• Don’t skip searing the roast; browning adds crucial flavor.
• If sauce is thin, reduce on stovetop or use a cornstarch slurry to thicken.
• Use a meat thermometer; roast is done when fork-tender, not by temp.
• Substitute beef broth with mushroom broth for extra umami.
• Over-salted broth can ruin the dish; taste and adjust before adding salt.
• If onions stick, add a splash of water or broth and scrape up fond.
• Leftover roast slices reheat better with a splash of broth to keep moist.

Serving Suggestions

• Serve with creamy mashed potatoes, buttered noodles, or crusty bread to soak up sauce.
• Pair with roasted root vegetables or a simple green salad for balance.
• Turn leftovers into sandwiches with provolone and extra caramelized onions. Try a different spin by pairing flavors from French Onion Meatloaf for a quick weekday lunch idea.
• For a lighter meal, serve over cauliflower mash or steamed green beans.

Storage & Leftovers

• Refrigerate cooled leftovers in an airtight container for up to 4 days.
• Freeze portions in freezer-safe containers for up to 3 months. Thaw overnight before reheating.
• Reheat gently on the stovetop with a splash of broth over low heat to preserve juiciness.

Nutrition Notes

This dish provides protein and iron from the beef and vitamin C plus fiber from onions. Using leaner cuts reduces saturated fat, while slow cooking retains nutrients. Choosing low-sodium broth and limiting added salt helps control sodium without sacrificing flavor.

Food Safety

• Always thaw frozen roast in the refrigerator, not at room temperature.
• Use a food thermometer if cutting time is uncertain; cooked beef should be properly reheated to steaming.
• Discard any leftovers left out over two hours at room temperature.
