Why You’ll Love This Recipe
Chuck roast is an excellent choice for the slow cooker because the long, gentle cooking process helps break down its connective tissue, resulting in tender beef that can easily be shredded with a fork.
The French onion soup mix provides savory onion flavor throughout the roast, while the sweet potatoes become soft and naturally sweet as they cook in the flavorful broth.
Since the beef and potatoes cook together, you get both the main course and a hearty side dish in one pot.
Ingredients
- 3–4 lbs raw beef chuck roast
- 2 large sweet potatoes, peeled and cut into 1-inch-thick rounds
- 1 packet dry French onion soup mix
- 1 cup beef broth
How to Make Slow Cooker French Onion Beef Roast
1. Add the Beef
Place the raw beef chuck roast directly into the bottom of the slow cooker insert.
Try to position the roast in the center so the sweet potatoes can be arranged around it.
2. Add the Sweet Potatoes
Arrange the sweet potato rounds evenly around the sides of the roast.
Cutting the potatoes into thick, approximately 1-inch rounds helps them hold their shape during the long cooking process while becoming tender.
3. Season Everything
Sprinkle the dry French onion soup mix evenly over the top of the beef and potatoes.
As the roast cooks, the seasoning combines with the beef juices and broth to create a flavorful pan sauce.
4. Add the Beef Broth
Carefully pour the beef broth around the edges of the slow cooker insert.
Try not to wash the seasoning completely off the top of the roast.
5. Slow Cook
Cover and cook on LOW for about 8 hours, or on HIGH for 4 to 5 hours, until the beef is fully cooked and tender enough to shred easily with a fork.
The sweet potatoes should also be soft and tender when pierced with a fork.
6. Shred and Serve
Once the beef is tender, shred it directly in the slow cooker using two forks.
Gently toss the shredded beef with the rich pan juices and serve hot alongside the tender sweet potatoes.
What Makes This Combination So Good?
Beef and sweet potatoes create a naturally satisfying balance. The chuck roast provides rich, savory flavor, while sweet potatoes add mild sweetness and a soft, creamy texture.
French onion seasoning ties everything together with its savory onion flavor. As the ingredients slowly cook, the broth becomes infused with the beef’s natural juices and seasoning, creating flavorful juices to spoon over the finished meal.
Helpful Tips for the Best Results
Cut the sweet potatoes evenly: Similar-sized pieces will cook more consistently.
Don’t cut the potatoes too thin: Thick rounds are better suited to the long cooking time and are less likely to become overly soft.
Use chuck roast for shredding: Its marbling and connective tissue make it particularly well suited for slow cooking.
Cook on LOW when possible: The longer cooking process is ideal for transforming chuck roast into tender, shreddable beef.
Check before serving: Cooking times can vary between slow cookers. The beef should be fully cooked and easily pull apart with a fork, while the potatoes should be tender.
How to Serve It
This meal is already hearty enough to serve on its own, but you can add a few simple sides if you’re feeding a crowd.
Try serving it with:
- Steamed green beans
- Roasted broccoli
- Dinner rolls
- Simple green salad
- Corn
- Sautéed vegetables
The flavorful pan juices can be spooned over both the beef and sweet potatoes for extra moisture and flavor.
Easy Leftover Ideas
Store leftover beef and sweet potatoes in airtight containers in the refrigerator and reheat until hot.
The shredded beef can also be used in sandwiches, wraps, rice bowls, or loaded baked potatoes. Leftover sweet potatoes make an easy side dish and can be reheated alongside the beef.
For the best texture, add some of the reserved pan juices when reheating the beef so it stays moist and flavorful.
