Instructions
1. Prepare the Roast

- This helps the seasoning stick and gives better browning.

- Sear the roast for 3–4 minutes per side until nicely browned.
- Transfer it to your slow cooker.
3. Add Vegetables

- Sprinkle the onion soup mix over the top.
4. Add Liquid
- Pour beef broth (or red wine) around the sides of the meat.
- Add a bay leaf for flavor.
5. Cook
- On Low: 8–9 hours
- On High: 4–5 hours
- The roast is ready when it’s easy to pull apart with a fork.
6. Make Gravy (Optional)
- Remove the roast and vegetables and keep warm.
- Skim excess fat from the liquid.
- Mix 1 tablespoon cornstarch with 2 tablespoons water and stir into the slow cooker juices.
- Cook on high for 5–10 minutes until thickened.

Pro Tips & Notes
- Choose the right cut: A chuck roast with marbling gives the best flavor and texture.
- Don’t rush the cook time: Low and slow gives you that fall-apart tenderness.
- Layer wisely: Vegetables go on the bottom; meat goes on top to keep it juicy.
- Let it rest: After cooking, let the roast sit for 10 minutes before slicing.
- Use leftovers: Shred any leftover beef for sandwiches or stews the next day.
