Instructions
Step 1: Prepare the Beef
Pat the chuck roast dry using paper towels. Season generously with salt, pepper, smoked paprika, garlic powder, and onion powder on every side.
Step 2: Sear the Roast
Heat olive oil in a large skillet or Dutch oven over medium-high heat.
Sear the roast for about 4–5 minutes on each side until a deep golden crust develops. This locks in flavor and creates a rich base for the gravy.

Step 5: Slow Cook
Cook:
- Low: 8–10 hours
- High: 5–6 hours
The meat should easily pull apart with a fork.
Step 6: Prepare the Mashed Potatoes
Peel and chop potatoes into evenly sized chunks.
Boil in salted water for about 20 minutes until fork tender.
Drain thoroughly.
Mash while hot.
Mix in:
- Butter
- Warm milk
- Heavy cream
- Garlic powder
- Salt
- Pepper
Beat until creamy and fluffy.
Step 7: Make the Gravy
Remove the roast.
Strain the cooking liquid if desired.
Mix cornstarch with cold water.
Whisk into the hot broth.
Simmer 3–5 minutes until thickened into a rich gravy.
Step 8: Assemble
