- 4 cloves garlic, minced For flavor enhancement.
- 2 tablespoons balsamic vinegar Promotes caramelization.

Instructions
Preparation
- Peel and slice the yellow and sweet onions into thin rings and mince the garlic.
- Set the crock pot to high.
- Add the butter, sliced onions, minced garlic, brown sugar, and balsamic vinegar to the crock pot and stir to combine.
- Cover and cook on high for 20–30 minutes until the onions soften and just begin to caramelize.
- Pro Tip: Onions are ready when they turn translucent and edges deepen to light amber.
Searing (Optional)
- Pat the chuck roast dry with paper towels and season all over with kosher salt and black pepper.
- Heat olive oil in a skillet over medium-high heat. Sear the roast for 2–3 minutes per side until you achieve a deep brown crust.
- Transfer to the crock pot and nestle on top of the caramelized onions.
- Pro Tip: Searing adds flavor through the Maillard reaction.
Assembly
- Sprinkle the roast and onions with thyme and tuck in the bay leaves.
- Pour in the beef broth, white wine, and Worcestershire sauce until the roast is partially submerged.
- Pro Tip: Liquid should come up to the midpoint of the roast.
Cooking
- Set the crock pot to low and cook for 8–9 hours, or set to high for 5–6 hours.
- Check tenderness after about 7 hours; the roast should shred easily.
- Pro Tip: The roast is done when an internal thermometer reads around 195–205°F.
Thickening the Gravy
- Mix the cornstarch with cold water until smooth and stir into the crock pot.
- Cook uncovered on high for 10–15 minutes until the gravy thickens.
Serving
- Sprinkle shredded cheese and chopped parsley over the roast if using.
- Serve hot, straight from the crock pot or on a serving platter.
Notes
Make-ahead tips: Caramelize the onions a day ahead and refrigerate. Reheat gently before serving. For a richer flavor, consider using a dry red wine instead of white.
