Ingredients
3 lb boneless chuck roast
1 1/2 tsp kosher salt
1 tsp black pepper
3 large onions, thinly sliced
8 oz cremini mushrooms, sliced
4 garlic cloves, minced
1 1/2 cups low-sodium beef broth
1 tbsp Worcestershire sauce
1 tbsp sherry vinegar
1 tsp dried thyme
2 tbsp butter
1 tbsp cornstarch mixed with 2 tbsp cold water
1 cup crispy fried onions, for topping
Directions
- Season the roast with the salt and pepper.
- Spread the onions, mushrooms and garlic across the bottom of the slow cooker.
- Set the roast on top of the vegetables.
- Whisk the broth, Worcestershire, vinegar and thyme and pour it over.
- Dot the roast with the butter.
- Cover and cook on LOW for 7 to 9 hours, until the roast shreds.
- Lift out the roast and break it into large pieces.
- Stir the cornstarch mixture into the juices on HIGH for 10 minutes until it coats a spoon.
- Return the beef to the gravy.
- Serve over noodles with crispy onions on top.
Notes
- If the gravy is too salty, thin it with a splash of water. Leftovers keep 4 days and freeze for 3 months in the gravy.
Why Crockpot French Onion and Mushroom Roast tastes sweet and tasty
Three onions cook down under the meat and turn sweet. Mushrooms add earthy depth. The sherry vinegar keeps it from tasting flat. The cornstarch finish gives the juices a gravy body.
The onions are sliced thin so they collapse into the juices. Mushrooms release liquid, and sherry vinegar adds a light, bright note. Crispy fried onions on top bring crunch, which is a nice contrast to the soft meat and gravy.
Swaps
Beef stock can replace part of the broth. Red wine instead of vinegar works too. Do not use a very lean roast. It will not shred. Skip pre-sliced bagged onions, which cook unevenly.
What to serve
Mashed potatoes, buttered noodles or toasted bread. Cheese on top, broiled for a few minutes, nods to the soup.
Leftovers and the usual slip
Keeps 4 days and freezes up to 3 months in the gravy. Salt the roast, but taste before adding more, since broth and Worcestershire carry plenty. Use cremini rather than white button mushrooms if you can. They hold their shape better and taste deeper after eight hours.
