Directions

Step-by-Step Instructions

  1. Peel and thinly slice the yellow and sweet onions into rings. Mince the garlic.
  2. Turn 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. (If preferred, you can sauté the onions in a skillet for about 10 minutes before adding to the crock pot.)
  3. Pat your chuck roast dry and season with salt and pepper. In a skillet, heat olive oil over medium-high heat and sear the roast for 2–3 minutes per side until deep brown (this step is optional but adds flavor).
  4. Once the onions are caramelized, nestle the roast on top in your crock pot. Sprinkle the thyme and bay leaves over it.
  5. Pour in the beef broth, white wine, and Worcestershire sauce. Make sure the roast is partially submerged; if it’s not, add more broth.
  6. Cover and set the crock pot to low for 8–9 hours or high for 5–6 hours, until the roast becomes fork-tender. Check around the 7-hour mark.
  7. Remove the roast and tent it with foil. Skim excess fat from the cooking liquid.
  8. Mix the cornstarch with cold water and stir it into the crock pot. Cook on high, uncovered, for about 10–15 minutes until the gravy thickens.
  9. Let the roast rest for 10 minutes before slicing or shredding. Return to the pot and spoon the onion gravy over it.
  10. For a decadent touch, sprinkle with shredded cheese and garnish with chopped parsley. Serve hot, either straight from the crock pot or on a serving platter.

Helpful Cooking Tips
