Ingredients

3 pounds beef chuck roast or round roast
1 ounce onion soup mix 1 envelope
¾ cup beef stock
1 ½ teaspoons ground garlic
¼ cup red wine optional, or just use all beef stock.
3 medium onions sliced
fresh thyme optional
2 tablespoons cornstarch optional

Instructions

Spray the inside of the slow cooker with non-stick cooking spray.
Put the sliced onions in the bottom.
Cover with beef broth.
Sprinkle with garlic.
Rub chuck roast on all sides with onion soup mix and place on top of onions. If there is any additional soup mix pour over the top of the roast.
Add a few springs of fresh thyme to the top if desired.
Cook on low for 8 hours, or up to 12.
Once done, shred the roast, removing any larger pieces of fat, and mix with the onions and broth.

Thicken the gravy - optional

After cooking, combine 1-2 tablespoon cornstarch and 1-2 tablespoon of the broth in a small bowl. Whisk into a paste. Add the remaining broth and cornstarch mixture into a saucepan and simmer, whisking to thicken it into gravy.

Notes

Storage:

Let the leftover pot roast cool a little bit, then transfer it to an airtight container. It'll keep in the fridge for three to four days or the freezer for up to three months.

Tips:

Use paper towels to blot off any extra moisture from the beef. This'll help the onion soup mix stick better, resulting in a more flavorful roast.
Your grocery store might call round roast by another name: rump roast.
