For the Main Dish
- Corned Beef Brisket (3-4 lbs.) – The star of the dish; tenderizes during cooking. Ensure it includes a seasoning packet for best flavor.
- Lager-style Beer (12 oz.) – Provides flavor and moisture; substitute with beef broth and 1 tbsp cider vinegar if avoiding alcohol.
- Kosher Salt (1.5 tsp + more to taste) – Enhances flavors; use sea or table salt as an alternative.
- Small Red Potatoes (1 lb.) – Contributes heartiness; any waxy potato will suffice.

How to Make Corned Beef Instant Pot
Prepare Aromatic Base: Begin by adding the sliced yellow onion, minced garlic, fresh thyme, and bay leaves to the bottom of the Instant Pot. This aromatic foundation will elevate the flavor of your dish beautifully.
Add Corned Beef: Gently position the corned beef brisket, fat-side up, right on top of the aromatics. Sprinkle the seasoning packet from the brisket evenly over the meat, and pour the lager-style beer around it to infuse moisture throughout the cooking process.
Pressure Cook: Secure the lid on the Instant Pot and set it to high pressure, cooking for 80 minutes. It’s crucial to resist the urge to open the lid during cooking—this ensures that the meat becomes perfectly tender.
Rest the Meat: Once the cooking time is complete, allow the meat to rest in the pot for about 10 minutes. This helps it retain its juices! Be sure to keep the cooking liquid in the pot for the next step.
Cook Vegetables: Carefully remove any excess liquid from the pot, reserving about 2 cups. Then, add the small red potatoes, large carrots, and small head of green cabbage. Pour the reserved liquid over the vegetables, sealing the lid again. Pressure cook for an additional 5 minutes until the veggies are tender.
Optional: Serve with a generous dollop of mustard for added zing!

Expert Tips for Corned Beef Instant Pot
Don’t Rinse the Meat: Rinsing the corned beef before cooking will wash away the essential brine that’s vital for flavor; cook it as is for the best taste.
Monitor Cooking Time: Keep an eye on the pressure cooking time to avoid tough or chewy meat; pressing the pressure release after 10 minutes helps preserve tenderness.
Adjust Flavor Wisely: If substituting the lager with broth, taste and adjust seasoning carefully, as different liquids can alter the richness of your corned beef instant pot dish.
Use Fresh Ingredients: Fresh garlic, thyme, and vegetables enhance the dish’s overall flavor profile; opt for fresh when possible to elevate your meal.
Experiment with Variations: Don’t hesitate to incorporate different vegetables or even experiment with unique spices; it’s a perfect way to make this dish your own!

Customize your corned beef adventure with these simple and exciting tweaks to enhance flavors and accommodate preferences!
- Dairy-Free: Swap lager beer with non-alcoholic beer or vegetable broth to keep it comforting without dairy.

- Spicy Kick: Toss in a few crushed red pepper flakes to the pot for a delightful heat that elevates the meal.
- Vegetarian Option: Try a mushroom and vegetable medley instead of corned beef for a savory, plant-based alternative that is equally filling.
- Sweet Review: Add a touch of brown sugar or honey to the cooking liquid for a subtle sweetness that nicely balances the savory elements.

Corned Beef Instant Pot Recipe FAQs
What kind of corned beef should I use for this recipe?
Absolutely! For the best results, choose a corned beef brisket weighing between 3 to 4 pounds that comes with a seasoning packet. This ensures that you get that ideal blend of flavors during cooking. Look for briskets that have a good amount of marbling for increased tenderness and flavor.
How do I store leftover corned beef?
I recommend placing leftover corned beef in an airtight container and storing it in the fridge, where it can last for up to 3 days. For longer storage, you can tightly wrap the corned beef in plastic wrap or foil before placing it in a freezer bag. It will keep well for up to 2 months in the freezer, preserving its deliciousness.
Can I freeze the cooked corned beef and cabbage?
Very! To freeze, let the cooked corned beef cool completely before slicing. Wrap the slices in plastic wrap, then place them in a freezer-safe bag or airtight container. You can freeze the cabbage and other vegetables separately, as they have a different texture once thawed. Both will keep for up to 2 months.
What should I do if my corned beef turns out tough?
Tough corned beef can be quite disappointing! To avoid this, ensure you follow the cooking times closely. If your meat does turn out tough, slice it thinly against the grain, and then simmer it gently in some broth or the cooking liquid for about 10 to 15 minutes on low heat. This can help tenderize and infuse flavor back into the meat.
Are there any dietary considerations for making corned beef?
Absolutely! It’s vital to note that corned beef is typically quite high in sodium due to the brining process. If you’re watching your salt intake, look for low-sodium options or adjust the amount of added salt in this recipe to suit your dietary needs. Additionally, ensure no one in your meal group has allergies to any ingredients like garlic or gluten, especially if substituting with beer in the recipe.
Can I use a slow cooker instead of an Instant Pot?
Yes, indeed! If you prefer using a slow cooker, you can cook the corned beef on low for about 8 hours instead of the high-pressure method. Simply follow the same preparation steps, including the aromatic base, then let it slowly cook while you go about your day. The result will be just as flavorful and tender, with the added benefit of having an aromatic house while it cooks!
