Step 1: Prep the Beef (5 minutes)
Pat the beef chunks dry with paper towels—this is important for good browning. Season all sides generously with the salt, pepper, smoked paprika, and garlic powder. I like to do this on a large plate so I can turn the pieces easily.
Step 2: Brown the Beef (Optional but Recommended, 8 minutes)
Heat the olive oil in a large skillet over medium-high heat. When it's shimmering, add half the beef chunks (don't crowd the pan or they'll steam instead of brown). Sear for 2-3 minutes per side until you get a nice golden-brown crust. Transfer to your slow cooker and repeat with the remaining beef.
Jessica's Tip: Yes, you can skip this step when you're really pressed for time. I've done it plenty of Wednesday mornings when I'm running late. The dish will still be delicious, just with slightly less depth of flavor.
Step 3: Layer the Vegetables (5 minutes)
If you browned the beef, there should be some browned bits in your skillet. Add the minced garlic to the hot pan and stir for 30 seconds until fragrant, then scrape everything into the slow cooker—that's pure flavor you don't want to waste.
Now, arrange the onion wedges around the beef in the slow cooker. Nestle the carrot pieces in between. Finally, arrange the cabbage wedges on top, fitting them in like puzzle pieces. It's okay if they're sitting high—they'll shrink down significantly as they cook.
Step 4: Make the Braising Liquid (2 minutes)
In a medium bowl or large measuring cup, whisk together the beef broth, tomato sauce, apple cider vinegar, brown sugar, bay leaves, thyme, and red pepper flakes (if using). The vinegar might seem like an odd addition, but trust me—it brightens everything up and helps tenderize the meat.
Step 5: Pour and Start Cooking
Pour the braising liquid over everything in the slow cooker. It won't completely cover the cabbage at first, and that's fine. Give the slow cooker a gentle shake to distribute the liquid, then cover with the lid.
Cook on LOW for 7-8 hours or HIGH for 4-5 hours. The beef should be fork-tender and the cabbage should be soft but still hold its shape in wedges.
Step 6: Check and Adjust (2 minutes)
When the cooking time is up, carefully remove the bay leaves. Taste the broth and adjust seasoning if needed—I usually add a pinch more salt and some black pepper. If the broth seems too thin (this happens sometimes depending on how much moisture your cabbage releases), you can leave the lid off for 20-30 minutes on HIGH to reduce it slightly.
Step 7: Serve (3 minutes)
Use a slotted spoon to carefully transfer the cabbage wedges to serving bowls, followed by the beef and carrots. Ladle the broth over everything. Sprinkle with fresh chopped parsley and serve with a dollop of whole grain mustard on the side if you like.
