Ingredients You’ll Need
- 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)
How to Make (Step-by-Step)
Season the beef
Season the beef chuck roast generously with salt, black pepper, and garlic powder. Rub the seasoning in so every bite gets flavor. I brown it quickly in a hot pan when I have time; it adds depth, but you can skip browning if you’re rushed.
Layer the slow cooker
Place the sliced onion in the bottom of a slow cooker, then lay the beef roast on top. The onions act like a little flavor bed and help the meat stay moist. I like to tuck some onions under the roast for maximum flavor.
Mix the gravy
In a bowl, whisk together the beef broth, brown gravy mix, and Worcestershire sauce. Pour the mixture over the beef. The packet does a lot of the work here, so don’t guilt-trip it — convenience has its place.
Cook low and slow
Cover and cook on low for 8 hours, or until the beef is fork-tender. Yes, eight hours sounds long, but patience turns cheap chuck into melt-apart goodness. If you only have a few hours, cook on high for 4–5 hours instead.
Thicken the gravy (optional)
Optional: Remove beef and whisk in a cornstarch slurry to thicken the gravy. Shred beef and return to the gravy. I usually mix 2 tablespoons of cornstarch with cold water, pour it in, and let the slow cooker simmer for a few minutes with the lid off.
Serve it up
To serve, place a scoop of mashed potatoes on each plate, top with shredded beef and ladle over plenty of rich gravy. Want to be fancy? Make a little well in the potatoes to cradle the gravy. Your guests will think you planned it.
Pro Tips for the Best Results
- Brown the roast first if you can. I do this about 50% of the time and always notice the difference. Browning adds caramelized flavor.
- Use low and slow for fork-tender beef. Don’t rush the process unless you like chewy surprises.
- Season gradually. Taste the gravy near the end and adjust salt and pepper. The gravy mix can be salty, so be cautious.
- Keep the lid on. Resist peeking; every time you lift the lid you add cooking time.
- Thicken wisely. Mix cornstarch in cold water first to avoid lumps. Add small amounts until you reach the thickness you like.
- Double the batch for company. The slow cooker loves leftovers and so will your future self.
Fun Variations & Topping Ideas
Variations:
- Swap brown gravy mix for mushroom gravy mix for an earthy twist.
- Add carrots and potatoes to the slow cooker for an all-in-one pot meal.
- Use red wine (½ cup) in the gravy mixture for richer flavor — I say this like I’m fancy, but it’s an easy upgrade.
Toppings:
- Fresh parsley for color and brightness.
- Sliced green onions for crunch.
- Shredded cheddar cheese if you want to go rogue and creamy.
- A dollop of sour cream to make it feel decadently smooth.
Storing and Reheating
- Refrigerate leftovers in an airtight container within two hours of cooking.
- Store for up to 4 days in the fridge. I rarely keep it past day two because I snack my way through it.
- To reheat: warm gently in a pot over medium-low heat, stirring occasionally. Add a splash of beef broth if the gravy looks stiff.
- For microwave reheating: cover loosely and heat in 60-second bursts, stirring between intervals to distribute heat.
- Freeze portions for up to 3 months. Thaw overnight in the fridge before reheating.
Frequently Asked Questions (FAQ)
How do I prevent dry beef in the slow cooker?
I sear the roast and keep the lid on. Also, check the liquid level and use beef broth generously. Low heat and ample moisture stop dryness every time.
Can I make this without a packet mix?
Yes. Combine 2 cups beef broth with 2 tablespoons tomato paste, 1 tablespoon soy sauce, 1 tablespoon cornstarch slurry, and seasonings to create a similar gravy. It tastes homemade and honestly, not that hard.
Can I pressure cook this instead?
Absolutely. Cook on high pressure for about 60 minutes with a natural release for tender results. Use caution when switching methods and check your pressure cooker manual.
Will this work with other cuts of beef?
Yes. Use any cut that breaks down with long, moist cooking, such as chuck roast, brisket, or even short ribs. I stick with chuck because it balances flavor and price.
Can I use instant mashed potatoes?
Yes, use prepared mashed potatoes or instant — whatever your pantry gods allow. I keep a bag of instant in the pantry as a backup. FYI: real mashed potatoes taste better, but instant does the job.

This Hearty Comfort Slow Cooker Beef Manhattan hits the sweet spot between easy and soulful. You get tender shredded beef, cozy gravy, and mashed potatoes with minimal effort and maximal payoff.
