Juicy French Onion Pot Roast
Equipment
- 1 Dutch oven
- 1 Slow cooker (optional)
Ingredients
Pot Roast
- 3.5 lb beef chuck roast 3 to 4 pounds; sub: blade roast or brisket
- Kosher salt to taste
- Black pepper to taste
- 2 tbsp neutral oil for searing
- 4 yellow onions large, thinly sliced
- 4 cloves garlic minced
- 3 cups low-sodium beef broth
- 1 tbsp apple cider vinegar or red grape juice for brightness

- 5 sprigs fresh thyme
- 1 bay leaf
- 1 tbsp tomato paste optional
To Finish the Gravy (optional)
- 1 tbsp cornstarch or all-purpose flour to thicken, optional
- 1 tbsp butter or a splash of oil, optional
Instructions
Make the Pot Roast
- Pat the chuck roast dry. Season all over with salt and pepper. Slice the onions and mince the garlic so everything is ready to go.
- Heat a large Dutch oven over medium-high with a film of oil. Sear the beef 3 to 4 minutes per side until deeply browned. Transfer to a plate.
- Lower heat to medium. Add a bit more oil if needed and the sliced onions with a pinch of salt. Cook, stirring occasionally, 15 to 20 minutes until golden and jammy. Stir in garlic for 30 seconds.
- Stir in tomato paste and cook 1 minute. Pour in 1/2 cup broth, scraping up browned bits. Add remaining broth, vinegar or grape juice, Worcestershire or soy, thyme, and bay leaf. Return the roast and any juices to the pot.
- Oven method: Cover and cook at 325°F for 3 to 3 1/2 hours, until the roast is tender and shreds easily. Slow cooker method: Transfer onions, liquid, and roast to a slow cooker. Cook on Low 8 to 9 hours or High 4 to 5 hours.
- Set the roast on a board to rest 10 minutes. Skim excess fat from the pot. For a thicker gravy, simmer and whisk in a cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon water) until glossy. Whisk in a knob of butter or a splash of oil for sheen, if you like. Adjust salt and pepper.
- Slice or shred the beef against the grain. Spoon over plenty of onions and gravy.

Step-by-Step Instructions to Make Juicy French Onion Pot Roast
1. Season and Prep
Pat the chuck roast dry. Season all over with salt and pepper. Slice the onions and mince the garlic so everything is ready to go.
2. Sear the Roast
Heat a large Dutch oven over medium-high with a film of oil. Sear the beef 3 to 4 minutes per side until deeply browned. Transfer to a plate.
3. Caramelize the Onions
Lower heat to medium. Add a bit more oil if needed and the sliced onions with a pinch of salt. Cook, stirring occasionally, 15 to 20 minutes until golden and jammy. Stir in garlic for 30 seconds.
4. Deglaze and Build the Braising Liquid
Stir in tomato paste and cook 1 minute. Pour in 1/2 cup broth, scraping up browned bits. Add remaining broth, vinegar or grape juice, Worcestershire or soy, thyme, and bay leaf. Return the roast and any juices to the pot.
5. Braise Low and Slow
Oven method: Cover and cook at 325°F for 3 to 3 1/2 hours, until the roast is tender and shreds easily. Slow cooker method: Transfer onions, liquid, and roast to a slow cooker. Cook on Low 8 to 9 hours or High 4 to 5 hours.
6. Finish the Gravy
Set the roast on a board to rest 10 minutes. Skim excess fat from the pot. For a thicker gravy, simmer and whisk in a cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon water) until glossy. Whisk in a knob of butter or a splash of oil for sheen, if you like. Adjust salt and pepper.
7. Slice and Serve
Slice or shred the beef against the grain. Spoon over plenty of onions and gravy.
Tips for Success
- Take time to sear. A dark crust adds big flavor to the gravy.
- Slice onions evenly so they caramelize, not burn.
- Keep it gentle. Low heat and patience make the roast tender.
- Taste and balance. A tiny splash of vinegar or grape juice at the end can brighten rich flavors.
- Rest before slicing to keep the juices in the meat.
Variations of Juicy French Onion Pot Roast
- Mushroom twist: Add 8 ounces sliced cremini with the onions.
- Smoky savor: Stir in 1/2 teaspoon smoked paprika or crisp a little turkey bacon to crumble over the top.
- Herb-forward: Finish with chopped parsley and a little extra thyme.
- Creamy onion gravy: Stir in a spoonful of sour cream off the heat.
Serving Suggestions: What to Pair with Juicy French Onion Pot Roast
- Buttery mashed potatoes or creamy polenta to catch every drop of gravy.
- Buttered egg noodles or garlic mashed cauliflower.
- Roasted carrots, green beans, or a simple arugula salad with lemon.
- Crusty bread for swiping the pan clean.
Storage & Reheating Instructions
- Cool completely, then refrigerate in an airtight container up to 4 days.
- Freeze in gravy up to 3 months. Thaw overnight in the fridge.
- Reheat gently on the stove over low, adding a splash of broth to loosen the sauce, or warm in a 300°F oven, covered, until hot.
- Gravy too thick after chilling? Loosen with broth. Too thin? Simmer to reduce or whisk in a little slurry.

FAQs
Can I use a different cut of beef? Yes. Brisket and bottom round both work. They may take a little longer and slice better than they shred.
Can I make this in an Instant Pot? Yes. Sear on Sauté, caramelize onions, add liquids, then pressure cook on High for 60 to 70 minutes with natural release 15 minutes. Thicken on Sauté if needed.
How do I keep the onions from burning? Use medium heat, stir occasionally, and add a small splash of broth if the pan looks dry before they turn golden.
How do I thicken the gravy? Simmer to reduce, or whisk in a cornstarch slurry and cook until glossy. Taste and season.
