I love this recipe because it’s as easy as it is impressive. Everything goes right into the slow cooker, and after a few hours, I get a hearty, flavorful roast that practically falls apart. The combination of French onion soup, onion soup mix, and garlic gives the sauce incredible depth, while the potatoes and carrots soak up all that delicious flavor. It’s one of those hands-off meals that makes the whole house smell amazing and always feels like a special occasion dinner.
Ingredients
(Note: All ingredient amounts are listed in the recipe card below.) 2 onions, sliced 3-pound chuck roast 1 pound baby potatoes, halved 3 large carrots, sliced 1 (10.5 oz) can French onion soup 1 envelope beefy onion soup mix 2 cloves garlic, minced 1 cup water Parsley, for garnish
Directions
I start by layering the sliced onions, halved potatoes, and carrots in the bottom of my slow cooker to create a flavorful base.
I place the chuck roast directly on top of the vegetables.
In a separate bowl, I whisk together the French onion soup, beefy onion soup mix, minced garlic, and water until everything is well combined.
I pour the mixture evenly over the roast and vegetables, making sure the meat is well coated.
I cover the slow cooker with the lid and cook on LOW for 8 hours or HIGH for 6 hours, until the beef is fork-tender and falling apart.
Once cooked, I garnish with freshly chopped parsley and serve it hot over mashed potatoes to soak up that flavorful gravy.
Servings and Timing
This recipe serves about 6 people and takes around 8 hours total when cooked on LOW, or 6 hours on HIGH. Prep time is only about 10 minutes, making it a perfect set-it-and-forget-it dinner.
Variations
Sometimes I like to add a splash of red wine or Worcestershire sauce to the broth for extra richness. For a thicker gravy, I remove the roast and whisk 1 tablespoon of cornstarch with 2 tablespoons of cold water, then stir it into the crockpot juices and let it cook for 10–15 minutes. When I want to switch things up, I use sweet potatoes instead of baby potatoes or toss in mushrooms for a deeper umami flavor.
Storage/Reheating
I store any leftovers in an airtight container in the refrigerator for up to 4 days. When reheating, I warm it gently on the stovetop or in the microwave, adding a splash of water or broth to loosen the gravy if needed. This dish also freezes beautifully—I let it cool completely, then freeze it (with the gravy) for up to 3 months. I thaw it overnight in the fridge before reheating.
FAQs
Can I sear the roast before slow cooking?
Yes, I sometimes brown the roast in a skillet first—it adds an extra layer of flavor and gives the gravy a deeper, richer taste.
Can I use a different cut of beef?
Definitely. Brisket or bottom round roast also work well, though chuck roast gives the most tender results.
Do I need to peel the potatoes?
No, I leave the skins on baby potatoes for texture and convenience—they hold up well during slow cooking.
Can I make this recipe in the oven?
Yes, I bake it covered in a Dutch oven at 325°F for about 3 hours or until the beef is tender.
How can I make the gravy thicker?
After cooking, I mix a cornstarch slurry (1 tablespoon cornstarch + 2 tablespoons water) into the liquid and cook for about 10 minutes on HIGH.
What can I serve it with besides mashed potatoes?
I love it with buttered egg noodles, roasted vegetables, or creamy polenta—it’s great with anything that soaks up the sauce.
Can I add more vegetables?
Yes, I often add mushrooms, celery, or parsnips for extra heartiness.
How do I keep the beef from drying out?
I make sure the roast is partially submerged in the liquid and cook it low and slow—it stays perfectly tender that way.
Can I use homemade French onion soup?
Absolutely. If I have homemade on hand, I use it instead of canned for a richer flavor.
Does it work with frozen beef?
It’s best to thaw the roast first for even cooking, but if I’m short on time, I add an extra hour to the cook time on LOW.
