Ingredients You’ll Need

Most of these items are likely already in your pantry or fridge. Using fresh onions and garlic makes a huge difference in the final taste.

3.5 lbs beef chuck roast
2 large yellow onions, thinly sliced
2 packets (1 oz each) dry onion soup mix
1 can (10.5 oz) condensed French onion soup
1 cup low-sodium beef broth
3 cloves garlic, minced
2 tablespoons unsalted butter
1 teaspoon dried thyme
0.5 teaspoon cracked black pepper
0.25 teaspoon kosher salt

Step-by-Step Directions

Pat the beef chuck roast dry with paper towels and season surfaces with salt and black pepper.
In a large skillet over medium-high heat, melt the butter and sear the roast on all sides until a deep brown crust forms, approximately 4 minutes per side.
Place the sliced yellow onions in an even layer at the bottom of the slow cooker crock.
Transfer the seared beef roast into the slow cooker, resting it on top of the onions.
In a separate bowl, whisk together the beef broth, condensed French onion soup, dry onion soup mix, minced garlic, and thyme until combined.
Pour the liquid mixture over the beef in the slow cooker.
Cover with the lid and cook on the ‘Low’ setting for 8 to 10 hours (or ‘High’ for 5 to 6 hours) until the internal temperature reaches 202°F (94°C) and the meat is fork-tender.
Remove the roast from the cooker and allow it to rest for 10 minutes before shredding or slicing.
Skim excess fat from the cooking liquid and serve the remaining onion gravy over the meat.

Best Ways to Enjoy It

Serve this roast warm with a big scoop of creamy mashed potatoes. The savory onion gravy is perfect for drizzling over everything. You can also pair it with some crusty French bread for dipping. A side of roasted carrots or green beans adds a fresh touch. Set the table, light a candle, and enjoy this comforting winter meal with your family.

Storage & Reheating

Store any leftovers in an airtight container in the fridge for 3-4 days. This dish actually tastes even better the next day as flavors meld. You can also freeze the cooked beef and gravy for up to three months. To reheat, simply place it in a 350°F oven for about 15 minutes. You can also use the microwave for a quick and easy lunch the next day. Always keep the meat covered in gravy to keep it moist.

Recipe Tips for Best Results

Don’t skip the sear because it adds so much depth and color to the meat.
Always slice your onions thinly so they melt into the gravy beautifully.
Use low-sodium beef broth to keep the salt levels perfectly balanced.
Cook on the low setting whenever possible for the most tender results.
For a winter gathering, double the onions for extra savory goodness.
Skim the fat from the top of the gravy before serving for a cleaner taste.
Let the roast rest before slicing to keep all the juices inside.
Add a splash of balsamic vinegar at the end to brighten the flavors.

What if I don’t have a slow cooker?

You can easily make this in a heavy Dutch oven instead. Follow the searing steps, then cover and bake at 300°F for about 3-4 hours. Check the meat periodically to ensure it is becoming fork-tender. It will taste just as delicious as the slow cooker version.
