- 1/2 teaspoon black pepper
- 1 teaspoon dried thyme (or 2 teaspoons fresh thyme)
- 2 bay leaves
For the Onions
- 3 large yellow onions, thinly sliced (about 4 cups)
- 1 large sweet onion, thinly sliced
- 4 cloves garlic, minced
For the Gravy
- 2 tablespoons balsamic vinegar
- 1 tablespoon brown sugar
- 2 tablespoons unsalted butter
- 1 1/2 cups beef broth (low-sodium preferred)
- 1/2 cup dry white apple vinegar (or more broth)
- 2 tablespoons Worcestershire sauce
For Thickening (Optional)
- 2 tablespoons cornstarch + 3 tablespoons cold water
For Serving (Optional)
- 1 cup shredded Gruyère or Swiss cheese
- Chopped fresh parsley (for garnish)
How to Make Crock Pot French Onion Pot Roast
Step 1: Prepare the Onions
Peel and slice yellow and sweet onions into thin rings. Mince garlic.
Step 2: Caramelize the Onions
Set crock pot to high. Add butter, onions, garlic, brown sugar, and balsamic vinegar. Stir well. Cover and cook for 20–30 minutes until onions soften and start to caramelize. Alternatively, sauté onions in a skillet for 10 minutes before transferring them to the crock pot.
Step 3: Season the Roast
Pat chuck roast dry with paper towels. Season generously with kosher salt and black pepper on all sides.
Step 4: Brown the Roast (Optional)
Heat olive oil in a skillet over medium-high heat. Sear roast for 2–3 minutes on each side until deeply browned.
Step 5: Combine Ingredients in Crock Pot
Once onions are caramelized, nestle the roast on top in the crock pot. Sprinkle thyme and bay leaves over everything.
Step 6: Add Liquids
Pour in beef broth, white apple vinegar, and Worcestershire sauce. Ensure that roast is partially submerged; add more broth if needed.
Step 7: Slow Cook
Set crock pot to low and cook for 8–9 hours or high for 5–6 hours until roast is fork-tender. Check after about 7 hours for doneness.
Step 8: Thicken Gravy
Remove roast from crock pot and tent with foil to keep warm. Skim excess fat from liquid in crock pot. Mix cornstarch with cold water until smooth; stir into liquid in crock pot. Cook on high without lid for 10–15 minutes until gravy thickens.
Step 9: Serve
Let roast rest for about 10 minutes before slicing or shredding. Return meat to crock pot; spoon onion gravy over top. If desired, sprinkle shredded cheese and chopped parsley before serving hot from the crock pot or transfer to a serving platter.

Common Mistakes to Avoid
When preparing your Crock Pot French Onion Pot Roast, avoiding common errors can enhance the final dish.
- Bold seasoning: Failing to season the meat adequately can lead to bland results. Always remember to season your roast with salt and pepper before cooking.
- Overcrowding the pot: Adding too many ingredients can prevent proper cooking. Make sure there is enough space for the roast and onions to cook evenly.
- Skipping the browning step: Not searing the roast may result in less flavor. Take a moment to brown the meat in a skillet for deeper flavors.
- Ignoring cooking times: Cooking for too long or too short can affect tenderness. Stick to recommended cooking times based on your crock pot setting.
- Neglecting rest time: Cutting into the roast immediately after cooking can cause juices to escape. Allow it to rest for at least 10 minutes before slicing or shredding.
