Key Ingredients & Substitutions
Corned Beef Brisket: I recommend using a well-trimmed 3 to 4 lb brisket for the best result. If you can’t find corned beef, try using a brisket cut and seasoning it with pickling spices.
Beef Broth: Homemade beef broth can elevate the flavor, but store-bought works fine too. If you’re looking to make it lighter, use water or vegetable broth instead.
Mustards: The combo of Dijon and whole grain mustards adds depth. You can mix any mustard you love; yellow mustard works as a basic substitute, but it will alter the flavor a bit.
Honey or Brown Sugar: Both sweeteners bring a nice balance to the glaze. If you’re looking for a sugar-free option, maple syrup is a great substitute.
How Do You Ensure the Corned Beef is Tender and Flavorful?
The secret to tender corned beef lies in the pressure cooking. Make sure to rinse the brisket well to reduce saltiness. Cooking it fat side up allows the juices to soak in during pressure cooking. Following these steps will yield a juicy, flavorful meat.
- Using natural pressure release after cooking allows the meat to relax and stay tender.
- Don’t forget to slice against the grain—this makes a big difference in tenderness!
What’s the Best Way to Make the Glaze Stick?
Brushing the glaze on the cooked corned beef helps to create that delicious caramelized layer. Broiling for just a few minutes is effective, but keep a close eye to prevent burning. A wire rack can help the glaze crisp up evenly.
- Try glazing the corned beef twice for an extra layer of flavor!
- If you prefer, skip the broiler and serve it right from the pot for an easier option.

How to Make Instant Pot Corned Beef With Mustard Glaze
Ingredients You’ll Need:
For the Corned Beef:
- 3 to 4 lb corned beef brisket, trimmed
- 4 cups beef broth (or water)
- 1 small onion, quartered
- 3 cloves garlic, smashed
- 2 bay leaves
- 1 tsp black peppercorns
- 1 lb baby potatoes, halved
- 4-5 baby carrots or regular carrots, peeled and cut into chunks
- Fresh parsley for garnish
For the Mustard Glaze:
- 3 tbsp Dijon mustard
- 2 tbsp whole grain mustard
- 2 tbsp honey or brown sugar
- 1 tbsp apple cider vinegar
- 1/2 tsp ground black pepper
- 1/4 tsp ground coriander (optional)
How Much Time Will You Need?
This delicious recipe takes about 15 minutes to prep and around 2 hours to cook, including the pressure cooking time and resting periods. Most of that time is waiting, so feel free to use it to prepare side dishes or relax!
Step-by-Step Instructions:
1. Prepare the Instant Pot:
Start by placing the trivet in the bottom of your Instant Pot. Pour in the beef broth (or water), and then add the quartered onion, smashed garlic, bay leaves, and black peppercorns. This will create a tasty base for your corned beef to cook in.
2. Cook the Corned Beef:
Next, rinse the corned beef brisket under cold water to get rid of any excess brine and seasonings. Lay the brisket on top of the trivet, fat side facing up. Seal the Instant Pot lid tightly and set it to cook on high pressure for 90 minutes. Once it’s done cooking, wait for about 15 minutes for the natural pressure release, then quickly release any remaining pressure.
3. Cook the Vegetables:
Carefully take the brisket out of the pot and set it aside to rest on a cutting board. Now, add the halved baby potatoes and the carrot chunks to the liquid in the Instant Pot. Seal the lid again and cook on high pressure for just 5 minutes. Once done, quick release the pressure and remove the vegetables.
4. Make the Mustard Glaze:
While your vegetables are cooking, you can make the mustard glaze! In a small bowl, mix together the Dijon mustard, whole grain mustard, honey (or brown sugar), apple cider vinegar, ground black pepper, and ground coriander (if using). Stir until everything is nicely combined.
5. Glaze and Finish:
Now it’s time to bring it all together! Place the cooked corned beef on your cutting board and brush it generously with the mustard glaze you just made. If you’d like, you can pop it under the broiler in the oven for 3-5 minutes to get the glaze bubbly and slightly caramelized—just keep a close eye on it so it doesn’t burn.
6. Slice and Serve:
Finally, slice the corned beef thinly against the grain. Plate it up alongside the cooked potatoes and carrots, and drizzle with any extra glaze or cooking juices. Don’t forget to add a sprinkle of fresh parsley for that finishing touch!
Enjoy your tender and flavorful Instant Pot Corned Beef with a tangy, sweet mustard glaze!
Can I Use Other Cuts of Meat?
Yes, you can! While corned beef brisket is traditional, you can use other cuts like corned beef round or even a pork shoulder. Just adjust the cooking time accordingly, as different cuts may require different times for tenderization.
How Should I Store Leftover Corned Beef?
Store any leftovers in an airtight container in the fridge for up to 3-4 days. You can also freeze the corned beef for up to 3 months. To reheat, gently warm in the microwave or slice and sauté in a pan for best results.
Can I Omit the Mustard Glaze?
Absolutely! If mustard isn’t your thing, you can skip the glaze and serve the corned beef as is. It will still be delicious with the flavors from the cooking liquid and the veggies!
What Are Some Side Dishes That Go Well With This Meal?
This corned beef pairs wonderfully with traditional sides like colcannon (mashed potatoes with greens), steamed cabbage, or a simple green salad. Feel free to enjoy it with your favorite sides too!
