THE CROCKPOT SUPPER CLUB • SEPTEMBER 22, 2026

By late September, the slow cooker begins to feel less like a convenience and more like an invitation to autumn. Beef, mushrooms, onions and carrots spend the day gently braising in a savory balsamic broth until everything is deeply flavored and wonderfully tender. Come evening, there is little left to do but finish the sauce and decide whether supper wants mashed potatoes, creamy polenta or simply a good piece of bread alongside.

Ingredients

For the slow cooker

• 2 pounds beef chuck roast, cut into 1½-inch pieces
• 1 tablespoon olive oil
• 1 large yellow onion, sliced
• 3 cloves garlic, minced
• 2 cups baby carrots
• 2 cups cremini mushrooms, halved
• 1 cup low-sodium beef broth
• ⅓ cup balsamic vinegar
• 2 tablespoons tomato paste
• 1 teaspoon dried thyme
• 1 bay leaf
• 1 teaspoon kosher salt, plus more to taste
• ½ teaspoon freshly ground black pepper

For the finish

• 1 tablespoon unsalted butter
• 1 tablespoon chopped fresh parsley

For serving

• Creamy mashed potatoes or soft polenta
• Buttered noodles, if you prefer
• Crusty bread

☀ 1 • In the Morning

1. Brown the beef. Heat the olive oil in a skillet over medium-high heat. Season the beef with salt and pepper and brown it in batches, taking care not to crowd the pan. Transfer the browned pieces to the slow cooker.
2. Add the vegetables. Add the sliced onion, garlic, carrots and mushrooms to the slow cooker with the beef.
3. Make the braising liquid. Whisk together the beef broth, balsamic vinegar, tomato paste and thyme until the tomato paste is incorporated.
4. Fill the slow cooker. Pour the balsamic mixture over the beef and vegetables and tuck in the bay leaf.

Cover and cook on LOW for 7–8 hours, until the beef is very tender.

◷ 2 • While You’re Away

The beef slowly braises until fork-tender while the onions soften, the mushrooms become savory and the carrots take on the rich balsamic cooking juices. By evening, the broth has become a deeply flavored sauce and the kitchen smells unmistakably like supper.

LOW • 7–8 HOURS

⌂ 3 • When You Get Home

1. Remove the bay leaf. Discard the bay leaf and skim away any excess fat from the surface of the cooking liquid if needed.
2. Finish the sauce. Stir the butter into the hot cooking liquid until melted. This rounds out the balsamic sauce and gives it a silky finish.
3. Finish and serve. Taste and adjust the salt and pepper, then sprinkle with chopped parsley and spoon the beef, vegetables and plenty of sauce over your chosen accompaniment.

A Little Flexibility

No mushrooms? Simply leave them out and add another carrot or two, or use parsnips for an autumn variation. If balsamic vinegar isn’t in the pantry, red wine vinegar can stand in with a small pinch of brown sugar to soften its sharper edge. Mashed potatoes make this particularly comforting, but polenta, buttered noodles or even a thick slice of toasted bread will happily catch the sauce.

To Serve

Spoon the balsamic beef and vegetables over creamy mashed potatoes or soft polenta, letting some of the rich cooking juices settle underneath. Buttered noodles make an easy alternative. Add a green salad and crusty bread if you’d like to stretch the supper a little farther.

Cook’s Note

Chuck roast is particularly well suited to this kind of long, gentle cooking. The connective tissue has time to soften during the slow braise, giving you tender beef and a richer cooking liquid. For an even deeper flavor, season the cubed beef and refrigerate it overnight before assembling the slow cooker the following morning.
