How to Make Crock Pot French Onion Pot Roast

Ingredients:

3–4 lb chuck roast (well-marbled)
2 tablespoons olive oil (for browning, optional)
1 teaspoon kosher salt
1/2 teaspoon black pepper
1 teaspoon dried thyme (or 2 teaspoons fresh thyme)
2 bay leaves
3 large yellow onions, thinly sliced (about 4 cups)
1 large sweet onion, thinly sliced
4 cloves garlic, minced
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 wine (or more broth)
2 tablespoons Worcestershire sauce
2 tablespoons cornstarch + 3 tablespoons cold water (for thickening, optional)
1 cup shredded Gruyère or Swiss cheese (optional)
Chopped fresh parsley (for garnish)

Directions:

Peel and slice the yellow and sweet onions into thin rings. Mince the garlic.
Set the crock pot to high. Add the butter, onions, garlic, brown sugar, and balsamic vinegar. Stir, cover, and cook for 20–30 minutes until the onions soften and start to caramelize. (Alternatively, sauté onions in a skillet for 10 minutes and transfer them to the crock pot.)
Pat the chuck roast dry and season with salt and pepper. Heat olive oil in a skillet over medium-high heat and sear the roast for 2–3 minutes per side until deep brown (optional).
Once the onions are caramelized, nestle the roast on top in the crock pot. Sprinkle thyme and bay leaves over everything.
Pour in the beef broth, white wine, and Worcestershire sauce. Ensure the roast is partially submerged; add more broth if needed.
Set the crock pot to low and cook for 8–9 hours, or high for 5–6 hours, until the roast is fork-tender and shreds easily. Check after 7 hours.
Remove the roast and tent with foil. Skim excess fat from the liquid. Mix cornstarch with cold water and stir into the crock pot. Cook on high, uncovered, for 10–15 minutes until the gravy thickens.
Let the roast rest for 10 minutes before slicing or shredding. Return to the crock pot and spoon onion gravy over the top.
Sprinkle with shredded cheese and chopped parsley. Serve hot, straight from the crock pot or on a serving platter.
