- Place the chuck roast in a slow cooker (crock pot).
- In a bowl, combine the brown gravy seasoning mix, ranch seasoning mix, Italian seasoning mix, and water. Stir well to combine.
- Pour the seasoning mixture over the chuck roast.
- Cover the slow cooker and cook on low for 10 hours.
- Once cooked, remove the roast from the slow cooker and set aside.
- Pour the cooking liquid from the slow cooker into a saucepan.
- In a separate bowl, mix a small amount of flour with cold water to create a slurry (this will prevent lumps in your gravy).
- Bring the cooking liquid in the saucepan to a simmer over medium heat.
- Slowly pour the flour slurry into the simmering liquid, whisking constantly to prevent lumps.
- Continue to simmer and whisk until the gravy has thickened to your desired consistency.
- Serve the gravy over the chuck roast.
Enjoy your delicious and easy crock pot roast!
