Slow Cooker Corned Beef Recipe
Introduction
Slow cooker corned beef is a comforting, tender dish perfect for a cozy meal. By cooking the brisket low and slow, the meat becomes incredibly soft and flavorful, absorbing the rich broth and seasoning. It’s a hands-off recipe that yields impressive results.

Ingredients
- 1 large onion, large dice
- 6 carrots, peeled, cut in large chunks
- 4 celery stalks, cut in large chunks
- 3-4 pounds corned beef brisket with seasoning packet, drained
- 4 cups unsalted beef stock
- 12 ounces lager beer (can use water, more beef stock, or a dark soda like Coke)
Instructions
- Step 1: Place the diced onion, peeled carrot chunks, and celery chunks into the bottom of an 8-quart slow cooker.
- Step 2: Set the drained corned beef brisket on top of the vegetables and sprinkle the seasoning packet evenly over everything.
- Step 3: Pour in the beef stock followed by the lager beer (or your chosen liquid) to surround the meat and vegetables.
- Step 4: Cover and cook on low for 8-9 hours. Cooking low and slow ensures the meat becomes tender and flavorful.
- Step 5: Remove the corned beef from the slow cooker, leaving the liquid and vegetables in the pot. You can discard or serve the vegetables alongside the meat.
- Step 6: Slice the corned beef against the grain and serve with some of the cooking liquid poured over to keep it moist.
Tips & Variations
- For extra flavor, add a few garlic cloves or a bay leaf to the slow cooker.
- Use dark beer like stout instead of lager for a richer taste.
- Serve with boiled potatoes and cabbage for a traditional meal.
- If you prefer a firmer texture, reduce cooking time to 6-7 hours on low.
Storage
Store leftover corned beef in an airtight container in the refrigerator for up to 4 days. Keep the cooking liquid separate to pour over when reheating. Reheat gently in a covered pan on low heat or in the microwave to avoid drying out the meat.

Ingredients
Vegetables
- 1 large onion, large dice
- 6 carrots, peeled, cut in large chunks
- 4 celery stalks, cut in large chunks
Main
- 3–4 pounds corned beef brisket with seasoning packet, drained
Liquids
- 4 cups unsalted beef stock
- 12 ounces lager beer (can substitute with water, more beef stock, or a dark soda like Coke)
Instructions
- Prepare Vegetables: Place the diced onion, peeled and chunked carrots, and chunked celery stalks into the bottom of an 8-quart slow cooker, creating a flavorful bed for the corned beef.
- Add Corned Beef: Place the drained corned beef brisket on top of the vegetables, then evenly sprinkle the seasoning packet over the meat and vegetables to infuse flavor.
- Add Liquids: Pour in the unsalted beef stock first, followed by the lager beer, ensuring the meat is well submerged to promote even cooking and flavor infusion.
- Slow Cook: Cover the slow cooker and cook on the low setting for 8 to 9 hours. Cooking on low allows the meat to become tender and succulent while preserving moisture.
- Remove and Serve: Once cooked, remove the corned beef from the slow cooker, leaving the liquid and vegetables behind. Optionally, discard the vegetables or serve them alongside the meat.
- Slice and Drizzle: Slice the corned beef against the grain for tenderness and serve with some of the cooking liquid drizzled over top to keep it moist and flavorful.
Notes
- For an extra punch of flavor, consider adding garlic cloves or bay leaves to the slow cooker.
- Cooking low and slow is key to tender corned beef; avoid cooking on high to prevent toughness.
- If you prefer a thicker sauce, you can thicken the cooking liquid with a slurry of cornstarch and water after removing the beef.
- Leftovers keep well refrigerated for 3-4 days and can be used in sandwiches or hash recipes.
- The beer can be substituted if desired; dark soda like Coke adds a touch of sweetness, while extra beef stock keeps the flavor rich and meaty.
