Why You'll Love This Recipe
I’ve made corned beef a few different ways, but using the Instant Pot is a total game changer. It’s quick, the meat turns out so juicy, and the veggies cook perfectly without turning to mush.
- Speedy Cooking: Pressure cooking cuts traditional cook times dramatically, so you can enjoy a hearty meal without the wait.
- Deep, Rich Flavor: The addition of Guinness beer adds that signature malty depth you just can’t get from broth alone.
- All-in-One Meal: From the brisket to the potatoes, carrots, and cabbage, everything cooks together in one pot for easy cleanup.
- Perfect for Gatherings: This recipe yields about 8 servings, making it ideal for sharing with family or friends on St. Patrick’s Day or any cold evening.
Ingredients & Why They Work
Choosing the right ingredients makes a big difference in this dish. For corned beef, look for a 3 ½ to 4 pound brisket with the pickling spice packet included—that packet is a flavor goldmine. And don’t skip the Guinness if you want that authentic Irish taste!

- Beef broth: Low-sodium broth keeps the flavors balanced and lets you control saltiness.
- Onion: Chunky pieces add sweetness and savoriness that infuse the broth as it cooks.
- Minced garlic: Simple, classic aromatics elevate the overall flavor profile.
- Guinness beer: Adds a hearty, malty note—feel free to substitute with more broth if you prefer.
- Corned beef brisket or round: The star of the show; pick one with the spice packet for that classic briny bite.
- Baby gold or red potatoes: Small potatoes cook evenly and soak up those delicious juices.
- Carrots: Large chunks hold their shape and add a pop of natural sweetness.
- Green cabbage: Cut into wedges for just the right tenderness after pressure cooking.
- Butter: Tossed with the vegetables for a rich, silky finish.
- Sea salt and black pepper: To season everything perfectly at the end.
- Fresh parsley: Adds a nice fresh herbal brightness as a garnish, if you like.
- Whole grain mustard: Optional but highly recommended for dipping that tender corned beef.
Make It Your Way
The beauty of this Instant Pot Corned Beef with Vegetables Recipe is how wonderfully adaptable it is. Whether you want to keep it traditional or mix things up a bit, there are plenty of ways to make it your own and suit your taste buds or dietary needs.
- Variation: I love adding a touch of fresh thyme or rosemary to the cooking liquid for a fragrant herbal note that complements the Guinness and spices beautifully. It’s a subtle twist that wakes up the usual flavors.
- Diet-friendly tweak: For a lower-carb version, swap the potatoes for rutabaga or turnips. They hold up well under pressure cooking and soak up all the savory broth flavors.
- Seasonal spin: In the fall, I sometimes substitute the cabbage with Brussels sprouts or add pearl onions for extra sweetness and texture diversity.
- Non-alcoholic option: If you prefer to skip the Guinness, just use extra beef broth with a splash of apple cider vinegar to keep that tangy, rich flavor layering intact.
Step-by-Step: How I Make Instant Pot Corned Beef with Vegetables Recipe

Step 1: Build Your Flavor Base
Start by pouring 2 cups of low-sodium beef broth into your 6- to 8-quart Instant Pot. Toss in the onion chunks and 2 teaspoons of minced garlic for that aromatic foundation. Place your 3½ to 4-pound corned beef brisket on top, fat side up, allowing that fat to baste the meat as it cooks. Pour the 11.2-ounce bottle of Guinness evenly over the brisket, then sprinkle on the pickling spices from the package. Securely lock the lid to trap all those wonderful aromas inside.
Step 2: Pressure Cook the Brisket to Perfection
Select the MANUAL or PRESSURE COOK function on HIGH pressure, and set the timer for exactly 1 hour and 25 minutes. Once the timer goes off, let the pressure release naturally for 10 minutes — this slow release helps maintain the tender, juicy texture of the meat. After that, carefully open the valve to perform a quick manual release for any remaining pressure.
Step 3: Prep the Veggies While the Meat Cooks
While the corned beef is working its magic, slice the core off the cabbage and place it cut side down on your board for stability. Cut it in half, then quarter each half to yield 8 wedges. Halve the baby gold or red potatoes and peel and cut the carrots into 3-inch chunks. Ready your vegetables for the next cooking step.
Step 4: Cook the Vegetables in the Instant Pot
Carefully remove the corned beef and tent it with foil to keep warm. Use a slotted spoon to fish out the cooked onions and discard them, leaving the flavorful cooking liquid behind. Add the potatoes and carrots into the pot first, then layer the cabbage wedges on top — just be sure not to fill the pot more than two-thirds full to ensure safe pressure cooking. Seal the lid again securely.
Step 5: Quick Pressure Cook for Tender Veggies
Set the Instant Pot to MANUAL or PRESSURE COOK on HIGH pressure for 5 minutes. As soon as the timer finishes, perform a quick pressure release to avoid overcooking the vegetables and preserve their bright colors and texture.
Step 6: Slice, Season, and Serve
Trim off the fat layer from the corned beef — especially important if you’re working with a flat cut brisket, which tends to be fattier. Slice the meat against the grain for maximum tenderness and arrange the slices neatly on a serving platter. Drizzle some of the cooking liquid on top to keep it moist and flavorful.
Transfer the potatoes, carrots, and cabbage to the platter or a separate serving bowl using a slotted spoon. Toss the vegetables gently with 3 tablespoons of butter and season with fine ground sea salt and freshly ground black pepper to taste. If you like, sprinkle some chopped fresh parsley for a pop of color and fresh aroma.
Don’t forget the finishing touch — serve this hearty meal with a dollop of whole grain mustard on the side for dipping. It’s the perfect tangy complement to the rich corned beef and buttery veggies.
Top Tip
To get the most out of your Instant Pot Corned Beef with Vegetables Recipe, these little tips can make a big difference in texture, flavor, and ease of cooking.
- Use Guinness for Depth: Adding Guinness beer infuses the brisket with a rich, slightly malty flavor that makes the dish truly memorable. If you prefer a milder taste, substituting extra beef broth is a great option.
- Natural Pressure Release Matters: Letting the pressure release naturally for 10 minutes after the corned beef cooks helps keep the meat tender and juicy, avoiding toughness.
- Don't Overfill Your Instant Pot: When cooking vegetables, keep the Instant Pot no more than two-thirds full to ensure even cooking and safe pressure buildup.
- Trim Fat Before Serving: Especially with flat brisket cuts, removing the fat layer before slicing makes your meal leaner and more enjoyable without sacrificing moisture.
How to Serve Instant Pot Corned Beef with Vegetables Recipe

Garnishes
A sprinkle of freshly chopped parsley adds a lovely pop of color and fresh flavor to brighten up your dish. Serve with whole grain mustard on the side for a zesty dip that complements the rich corned beef beautifully.
Side Dishes
This hearty meal is traditionally complete with the included cabbage, potatoes, and carrots, but if you want to add variety, creamy horseradish sauce, crusty Irish soda bread, or a crisp green salad make wonderful accompaniments.
Make Ahead and Storage
Storing Leftovers
After enjoying your meal, store any leftovers in airtight containers and refrigerate for up to 3 days. This helps lock in moisture and flavor, so you can enjoy delicious corned beef again soon.
Freezing
If you want to keep leftovers longer, you can freeze the cooked corned beef and vegetables in freezer-safe containers or bags. For best quality, use within 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat leftovers gently in a saucepan over low heat or in the microwave with a splash of the cooking liquid to maintain moisture. Avoid overheating, which can dry out the meat and toughen the vegetables.

Ingredients
Broth and Aromatics
- 2 cups low-sodium beef broth
- 1 medium white or yellow onion, cut into 5 or 6 chunks
- 2 teaspoons minced garlic
- 11.2 ounce bottle Guinness beer (or additional broth as substitute)
Corned Beef
- 3 ½ to 4 pound corned beef brisket or round, with pickling spice packet
Vegetables
- 1 pound baby gold or red potatoes, halved (fingerling potatoes work well too)
- 4 large carrots, peeled and cut into 3-inch chunks
- 1 small head green cabbage, cut into 8 wedges
Finishing
- 3 tablespoons butter
- Fine ground sea salt, to taste
- Freshly ground black pepper, to taste
- 2 tablespoons chopped fresh parsley, optional garnish
- ¼ cup whole grain mustard, optional for dipping
Instructions
- Prepare the cooking liquid: Add the beef broth, onion chunks, and minced garlic to the insert of a 6- to 8-quart Instant Pot. Place the corned beef brisket on top of the mixture, fat side up. Pour the Guinness beer evenly over the brisket and sprinkle the included pickling spices on top. Close and lock the Instant Pot lid securely.
- Pressure cook the corned beef: Select the MANUAL or PRESSURE COOK setting on the Instant Pot, set to HIGH pressure, and cook for 1 hour and 25 minutes. Once the cooking time is complete, allow the pressure to naturally release for 10 minutes, then carefully perform a manual release to let out any remaining pressure.
- Prepare the vegetables: While the corned beef cooks, slice the core end off the cabbage and place it cut side down for stability. Cut the cabbage in half and then into quarters to yield 8 wedges. Halve the potatoes and peel and cut the carrots into large chunks.
- Cook the vegetables: Remove the corned beef from the Instant Pot and tent it with foil to keep warm. Use a slotted spoon to remove and discard the cooked onions from the pot, leaving the cooking liquid inside. Add the potatoes and carrots to the Instant Pot, then arrange the cabbage wedges on top, ensuring the pot is not more than two-thirds full. Close and lock the lid again.
- Pressure cook the vegetables: Select MANUAL or PRESSURE COOK on HIGH, setting the time for 5 minutes. When cooking completes, quickly release the pressure manually.
- Finish and serve: Slice off the fat layer from the corned beef, especially if using a flat brisket. Cut the meat against the grain into slices and place on a serving platter. Drizzle some cooking liquid over the meat. Use a slotted spoon to transfer the potatoes, carrots, and cabbage to the platter or a serving bowl. Toss the vegetables with butter and season with salt and pepper. Garnish with chopped fresh parsley if desired. Serve grainy mustard on the side for dipping.
Notes
- Using Guinness beer adds a rich depth of flavor, but substituting additional beef broth works for a milder taste.
- Natural pressure release after the first cooking stage helps maintain meat tenderness.
- Do not overfill the Instant Pot with vegetables; keep below two-thirds capacity for safe cooking.
- For leaner meat, trim excess fat before serving or after cooking.
- Leftovers can be refrigerated for up to 3 days and reheated gently to preserve moisture.
