Jump to Recipe
Slow Cooker Pot Roast is the classic Sunday dinner made easy. A chuck roast cooks low and slow with carrots, potatoes and onions until it is so tender it falls apart with a fork.
The cooking juices turn into a rich gravy, and the whole house smells wonderful while it cooks.
Why You’ll Love This Slow Cooker Pot Roast
- Fork-tender beef every time
- Dinner cooks while you go about your day
- One pot for meat, vegetables and gravy
- Perfect for Sunday suppers and holidays
Ingredients You’ll Need
Choose a 3 to 4 pound chuck roast, which has the marbling needed for tender results. Baby potatoes and whole carrots hold their shape during the long cook.
How to Make Slow Cooker Pot Roast
Season and sear the roast, place it on onions in the slow cooker, add broth and seasonings, and top with carrots and potatoes. Cook on low for 8 hours, then thicken the juices into gravy.
Tips for the Best Slow Cooker Pot Roast
- Searing the roast adds deep flavor
- Do not trim all the fat, because it keeps the meat juicy
- Add the vegetables on top so they do not get mushy
- Cook until the meat shreds easily
Variations
- Add a splash of red wine to the broth
- Use sweet potatoes in place of baby potatoes
- Add mushrooms for extra savory flavor
How to Store and Reheat
Refrigerate in the juices for up to 4 days. Reheat gently. Freeze for up to 3 months.
Why This Slow Cooker Pot Roast Works
Slow Cooker Pot Roast works because chuck roast is full of connective tissue, which is tough when cooked quickly but turns tender and silky after hours of gentle heat. The low, steady temperature slowly breaks that tissue down into gelatin, which is why the meat shreds with a fork and the juices turn rich and glossy.
Searing the roast first adds deep, roasted flavor, and the broth and Worcestershire sauce give the cooking liquid a savory depth. Vegetables on top cook in the steam and soak up all those juices without turning to mush.
Ingredient Notes and Substitutions
- Beef: A 3 to 4 pound chuck roast is ideal. Bottom round or brisket flat also work, but may be less tender
- Vegetables: Baby potatoes and thick carrot pieces hold their shape. Parsnips, celery and mushrooms are good additions
- Liquid: Beef broth works best. A splash of red wine, about 1/2 cup, adds depth
- Herbs: Fresh thyme and a bay leaf are lovely. Use 1 teaspoon of dried thyme if that is what you have
- Gravy: Whisk 2 tablespoons of cornstarch with cold water and simmer it into the juices until thick, or use a flour and butter roux
Common Mistakes to Avoid
- Using a lean cut, like eye of round, which can turn dry and stringy
- Cutting vegetables too small, so they turn mushy after hours of cooking
- Cooking on high when you have time, since low gives more tender meat
- Filling the slow cooker with too much liquid, which dilutes the flavor
What to Serve With Slow Cooker Pot Roast
Pot roast is a complete meal with its vegetables, but a few extras make it feel like a Sunday supper. Serve it with creamy mashed potatoes, buttered egg noodles or warm dinner rolls to catch the gravy. Green beans, roasted Brussels sprouts or a simple side salad add freshness, and leftovers make excellent sandwiches the next day.
Frequently Asked Questions
What cut of beef is best?
Chuck roast is best, because its connective tissue melts into tender, juicy meat when slow cooked.
Should I cook pot roast on low or high?
Low for 8 to 10 hours gives the most tender results. High for 4 to 5 hours also works.
How do I make gravy?
Whisk 2 tablespoons of cornstarch with cold water, stir it into the hot juices and simmer until thick.
Why is my pot roast tough?
It usually needs more time. Chuck roast gets tender after it passes the tough stage, so keep cooking until it shreds easily with a fork.
Can I put frozen roast in the slow cooker?
For food safety, thaw the roast in the refrigerator first. A frozen roast can stay too long in the temperature range where bacteria grow.
