Notes from my kitchen

This beef shoulder roast was one of the most popular dinners at our meal assembly stores, and I think the distinctive gravy had a lot to do with it.

The sauce ingredients may sound like an unusual combination. But red wine, ketchup, Dijon mustard, Worcestershire sauce, and mushrooms cook down into an incredibly rich and tangy sauce.

I always have plenty of cauliflower mash on hand to soak up every last drop of the gravy, which becomes silky smooth once it thickens in the crock-pot.

Ingredients

Here's what you'll need to make this slow cooker beef shoulder roast recipe:

Of special note:

Boneless beef shoulder roast - This relatively lean cut becomes tender in a slow cooker but still holds together well for slicing. Look for a boneless shoulder roast, shoulder clod roast, or English roast. Chuck roast also works, but it has more fat and tends to fall apart more easily.
Mushrooms - I often use white mushrooms because they are readily available, but shiitake mushrooms, with a deep, slightly smoky flavor, are one of my favorites for a special occasion. Cremini or baby bella mushrooms work well too. Use up to 16 ounces if you really love mushrooms.
Red wine - I used Merlot wine. But Cabernet Sauvignon or Pinot Noir also work well. Choose a dry red wine you enjoy drinking, not a sweet one.

Brown the shoulder roast

Add the shoulder roast, mushrooms, and onions to the slow cooker, then pour the sauce on top. Cook on low for 4-6 hours or on high for 3-4 hours. It should be fork-tender and easy to slice.

Thicken the sauce

FAQ

Is it better to cook beef shoulder roast on high or low in a crockpot?

I prefer low heat because the roast cooks more gently and stays tender while still holding together for slicing. Check for doneness at the beginning of the range.

Why is my beef shoulder roast tough?

If the roast is still tough, it usually needs more time. Continue cooking until a fork or sharp knife slides in easily. However, because shoulder roast is leaner than chuck, avoid cooking it much longer than needed once it becomes tender.

What to serve with beef shoulder roast

For an everyday dinner, I like to keep the sides simple and let the red wine mushroom gravy do the heavy lifting. Roasted cauliflower rice is a lighter option that works especially well with the rich sauce, while crispy green beans or Parmesan broccoli bites add a green vegetable.

For a special occasion, I usually make crock-pot mashed potatoes with cream cheese and serve rolls to sop up the gravy.

And if I’m turning it into a full celebration dinner, flourless chocolate cake with ganache is a decadent finish.
