Flat lay of a whole uncut corned beef brisket with pickling spices scattered nearby, a medium yellow onion cut into large chunks, several whole unpeeled large carrots, quartered wedges of fresh green cabbage, halved baby gold and red fingerling potatoes, Save
  • Low-sodium beef broth: This forms the base liquid and keeps the dish rich without being overly salty.
  • White or yellow onion: Adds sweetness that melts into the broth for that almost caramelized depth.
  • Minced garlic: A tiny kick that brightens up the whole recipe.
  • Guinness beer: I use Guinness Draught for its distinctive flavor, but you can swap with more broth if you prefer.
  • Corned beef brisket or round: The star of the dish; look for one with the pickling spice packet included.
  • Baby gold, red, or fingerling potatoes: These hold up nicely under pressure without falling apart.
  • Carrots: Cut into large chunks so they cook evenly without mushiness.
  • Green cabbage: Classic pairing that steams beautifully without losing texture.
  • Butter: Toss the veggies in butter for extra richness and silky finish.
  • Sea salt and black pepper: To season to your taste after cooking.
  • Fresh parsley (optional): Adds a pop of color and fresh flavor as garnish.
  • Whole grain mustard (optional): Perfect for dipping—adds a tangy contrast to the savory meat.

Variations

I love playing around with this recipe depending on the season or what I have on hand. Don’t hesitate to swap veggies or tweak the flavor—it all works beautifully.

  • Swap the Beer: Once, I used a dark ale when I ran out of Guinness, and it still gave the broth a lovely richness.
  • Vegetarian version: For a twist, try making the veggies with vegetable broth and skip the corned beef altogether for a hearty, vegan Irish stew.
  • Add onions back in: Some folks like tossing extra onion wedges in with the veggies for more sweetness and texture.
  • More spices: If you want extra zing, sprinkle a little crushed red pepper or mustard seeds before cooking.

How to Make Instant Pot Corned Beef and Vegetables Recipe

A white plate holds a meal with three layers: on the left, a wedge of cooked cabbage, yellowish with black specks; next to it, a group of small baby potatoes, light brown and shiny; and two bright orange carrots garnished with green herbs placed among the Save

Step 1: Prep and Layer Your Ingredients

First, pour the beef broth into the Instant Pot, then add your onion chunks and minced garlic—these add a subtle sweetness and aroma that infuse the entire dish. Then, place your corned beef brisket right on top with the fat side up. Pour the Guinness over everything, and sprinkle the included pickling spice packet on the brisket. Lock the lid and get ready—this layering is key because it keeps the meat moist and flavors well distributed.

Step 2: Pressure Cook the Corned Beef

Select the manual or pressure cook setting on high, and set your Instant Pot for 1 hour and 25 minutes. After it finishes, let it naturally release for 10 minutes before manually releasing the rest. This natural release helps keep the brisket tender and juicy—don’t rush this part or your meat might get tough!

Step 3: Prepare and Add Vegetables

While the beef cooks, prep your vegetables. Slice the cabbage into eighths, halve the baby potatoes, and cut carrots into big chunks—about 3 inches each. Once the beef is done, remove it and tent with foil to keep warm, then discard the onions from the pot. Add the potatoes and carrots, then nestle the cabbage wedges on top without overfilling the pot (no more than two-thirds full is best).

Step 4: Pressure Cook the Vegetables

Close the lid again and set the Instant Pot to manual/high pressure for 5 minutes. When done, quick-release the pressure. The veggies will be perfectly tender but still holding their shape. If you like them softer, give an extra minute or two, but don’t overdo it!

Step 5: Slice and Serve

Carefully trim off any thick fat layer from the brisket, then slice against the grain for the most tender, easy-to-chew pieces. Arrange the beef and veggies on a platter, drizzle a bit of the cooking liquid over the meat for moisture, and toss the vegetables with butter, salt, and pepper. Sprinkle with parsley if you want that fresh, bright finish, and don’t forget a side of whole grain mustard for dipping—it takes the flavor up a notch.

Pro Tips for Making Instant Pot Corned Beef and Vegetables Recipe

  • Fat Side Up: I’ve learned that always placing the fat side up lets the fat baste the meat as it cooks, making it juicier and more flavorful.
  • Don’t Skip Natural Release: Allowing natural release for at least 10 minutes prevents the corned beef from toughening up due to sudden pressure changes.
  • Cut Veggies Uniformly: Cutting potatoes and carrots into similar-sized chunks ensures they cook evenly and finish at the same time.
  • Use the Cooking Liquid: Drizzling some cooking liquid over the sliced beef before serving keeps it moist and adds that rich, seasoned flavor your family will love.

Garnishes

I usually keep it simple and fresh—chopped parsley over the veggies brightens the plate and gives a little herbal zing. A smear of whole grain mustard on the side is a must for me, it perfectly complements the savory brisket.

Side Dishes

While the meal is filling on its own, I love pairing it with crusty rye or sourdough bread to soak up all those flavorful juices. A crisp green salad or pickled beets also add a refreshing contrast to the hearty main.

Creative Ways to Present

For special occasions, I sometimes serve the sliced corned beef on a large wooden board with veggies arranged artfully around it, adding lemon wedges and fresh herbs for a rustic but elegant vibe. It always gets compliments and makes the meal feel extra festive.

Make Ahead and Storage

Storing Leftovers

I store leftover corned beef and vegetables in airtight containers in the fridge for up to 4 days. Keeping the cooking liquid with the meat helps it stay moist and flavorful. When I pack lunch, I sometimes pour a little of that broth over the beef before reheating.

Freezing

This recipe freezes surprisingly well! I slice the meat and portion it with veggies into freezer bags, adding a bit of broth to keep everything juicy. When I defrost, it almost tastes as good as freshly made.

Reheating

To reheat, I gently warm up the corned beef and veggies with some cooking liquid in a covered pan or microwave with short bursts, stirring occasionally. This keeps the meat tender and prevents the veggies from drying out.

Final Thoughts

I absolutely love how this Instant Pot Corned Beef and Vegetables Recipe brings together classic flavors into a fast, comforting meal that feels like a warm hug. Whether you’re making it for a special holiday or just a cozy weekend dinner, you’ll enjoy how simple it is without sacrificing any of that rich, traditional taste. Give it a try—you might just find it becomes a new family favorite like it did in my home!
