Ingredients You’ll Need
A handful of ingredients, slow-cooked to perfection, make this dish taste like it’s been simmering in grandma’s kitchen all day.
Main Ingredients
- 2 lbs beef chuck roast, trimmed
- 1 large onion, sliced
- 2 cups beef broth
- 1 packet brown gravy mix (about 1 oz)
- 1 tablespoon Worcestershire sauce
- 3 cups mashed potatoes, prepared
- 1 teaspoon garlic powder
- Salt and black pepper, to taste
- 2 tablespoons cornstarch (optional, for thickening)
Optional Add-Ons or Substitutes
- Add sliced mushrooms for umami depth.
- Swap mashed potatoes for buttered egg noodles.
- Use onion soup mix for a bolder flavor.
- Substitute chuck roast with top round if preferred.
- Add fresh thyme or rosemary for extra aroma.
- Use low-sodium broth if watching salt intake.
Step-by-Step Instructions
Let your slow cooker do all the heavy lifting — this meal practically makes itself.
- Prepare the Beef:
Season the chuck roast with salt, pepper, and garlic powder. Place in the slow cooker. (I like to sear mine in a skillet first for a richer flavor, but it’s optional.) - Add the Flavor Base:
Add sliced onions on top of the beef. In a small bowl, whisk together beef broth, gravy mix, and Worcestershire sauce. Pour over the roast. - Slow Cook to Tender Perfection:
Cover and cook on Low for 7–8 hours or High for 4–5 hours, until the beef is fork-tender. - Thicken the Gravy (Optional):
Remove beef and shred it slightly. Mix 2 tablespoons cornstarch with ¼ cup water and stir into the cooking liquid. Cook for 15 minutes more until thickened. - Serve It Up:
Spoon mashed potatoes onto plates, top with beef and rich gravy, and serve warm.
Quick Reminders:
- Trim excess fat before cooking to prevent greasy gravy.
- Stir halfway through if you can — it helps flavors mix.
- Add more broth if gravy thickens too much.
- Don’t rush the slow cook — low and slow equals tender!
Expert Tips for Success
Slow cooker recipes are all about patience and layering flavor.
- Sear the beef first for deeper flavor and color.
- Use real mashed potatoes — the texture pairs beautifully with the gravy.
- Deglaze the pan after searing with broth to grab all those caramelized bits.
- If too salty, add a splash of cream or more water to balance.
- Pair it with Garlic Parmesan Dinner Rolls to soak up every drop of gravy.
- Serve alongside Hearty Cabbage Beef Bake for a true homestyle dinner.
- For a complete cozy meal, try it with Zuppa Toscana Casserole.
With just a few ingredients, this recipe turns into a dinner that feels like a warm hug.
