- 1 teaspoon crushed red pepper flakes: Gives a gentle kick, but you can adjust based on your heat tolerance.
- 1 teaspoon black pepper: Adds a slight warmth and seasoning to the meat.
- 1 teaspoon kosher salt: Essential for enhancing flavors; adjust to taste.
- 1 small onion, roughly chopped: Its sweetness caramelizes during cooking, enriching the dish.
- 4 carrots, peeled and cut into 2-inch chunks: Adds sweetness and color, making the dish more vibrant.

How to Make Slow Cooker Corned Beef
- Prepare the Brisket: Place the 3-pound brisket flat in your slow cooker, making sure it fits nicely. Rubbing the underside helps flavor the meat.
- Season the Meat: In a small bowl, mix together the 1 tablespoon dried ground mustard, 1 teaspoon dried ground coriander, 1 teaspoon dried dill, 1 teaspoon crushed red pepper flakes, 1 teaspoon black pepper, and 1 teaspoon kosher salt. Rub this seasoning blend over the top of the brisket, ensuring it’s evenly coated.
- Add the Vegetables: Surround the brisket with the chopped onion, 4 carrots cut into 2-inch chunks, and 6 oz of red baby potatoes. Nestle the vegetables snugly around the meat to get maximum flavor.
- Slow Cook: Cover the slow cooker with the lid and set it to cook on high for 3-4 hours or low for 6-8 hours. As it cooks, the brisket will become tender and the vegetables will absorb the rich flavors.
- Slice and Serve: Once the cooking time is up, carefully remove the brisket from the slow cooker and let it rest for about 15 minutes. This brief resting period allows the juices to redistribute, making for a more flavorful cut. Slice the brisket thin against the grain to ensure maximum tenderness and serve with the vegetables.
Storing & Reheating
To store leftover Slow Cooker Corned Beef, place it in an airtight container in the refrigerator, where it will last for up to 3 days. If you want to keep it longer, you can freeze it for up to 3 months; just be sure to cut it into slices and separate the portions to make reheating easier. When it’s time to enjoy again, simply reheat the slices in a pan on low or in the microwave, and you’ll find that the flavors deepen even further. While the texture might change slightly after freezing, a little broth or water can help refresh it.
Chef’s Helpful Tips
- If you prefer a leaner cut, look for a brisket labeled as “flat-cut;” it has less fat, which can lead to a drier texture if overcooked.
- To avoid mushy vegetables, add the cabbage wedges in the last hour of cooking, so they retain more structure.
- For extra flavor, consider adding a bay leaf or two to the slow cooker.
- Always slice against the grain; this means cutting through the lines of muscle, which makes each bite more tender.
- Experiment with adding different veggies like parsnips or celery for variation!
Slow Cooker Corned Beef is not just a meal; it’s an experience that gathers loved ones around the table. The rich aroma of spices and savory brisket wafting through your kitchen is sure to create memories that you’ll cherish.
