What is Corned Beef?

Corned Beef is a beef roast, usually the brisket, that has been salt-cured to tenderize and preserve the meat. And did you know that Corned Beef is not actually a traditional Irish food, but something Irish people started eating when they came to America. Here’s more about corned beef and why it’s popular for St. Patrick’s Day. And check out Low-Carb and Keto Corned Beef Recipes for more ideas for cooking corned beef or using leftover corned beef.

How Long Should You Cook Corned Beef in the Instant Pot?

Cooking corned beef in the pressure cooker is so foolproof and easy that you barely need a recipe, but when I first tried it I checked a lot of sources online for tips, and I did find variations in the suggested cooking time. Over and over people recommended 90 minutes at high pressure, and that will produce ultra-tender corned beef. But if you want corned beef that holds together well for sandwiches, I’d cut the cooking time down to 80 minutes.

What Size Instant Pot Did I Use?

I used a 6 Quart Instant Pot (affiliate link) for this recipe, but you can make this in any electric pressure cooker or stovetop pressure cooker as well. Check out my growing collection of Instant Pot Recipes! You can also find lots more Instant Pot Recipes on my other site, Slow Cooker or Pressure Cooker.

How to Make Instant Pot Corned Beef with Creamy Horseradish Sauce:

(Scroll down for complete printable recipe and nutritional information.)

  1. If you can get flat cut corned beef it will be easier to slice. Most of the time one side will have quite a thick layer of fat. I cut off most of that, and the fat that was left scraped off easily once the meat was cooked.
  2. You can use the spice packet that comes with the meat if you prefer, but I used just Bay Leaves (affiliate link), peppercorns, Dried Thyme (affiliate link), and an onion to flavor the meat and two cans of low-sodium chicken broth for the liquid. 
  3. Set the pressure cooker or Instant Pot to MANUAL, HIGH PRESSURE, 90 minutes. (If you want meat that’s a bit less fall-apart tender so you can slice it for sandwiches, you can reduce the time to 80 minutes.)
  4. When time is up, use the natural release method for 20 minutes and then release any additional pressure.
  5. While the corned beef cooks, mix together sour cream and mayo and stir in cream style horseradish to taste to make a spicy sauce.
  6. Slice corned beef against the grain to serve.
  7. Serve hot and enjoy!

Yield: 8 servings

Instant Pot Corned Beef with Creamy Horseradish Sauce

Prep Time 15 minutes
Cook Time 1 hour 30 minutes
Additional Time 20 minutes
Total Time 2 hours 5 minutes

Use the pressure cooker or Instant Pot to cook your corned beef for St. Patrick’s Day!


  • 4 pound flat cut corned beef
  • 4 large bay leaves (see notes)
  • 8 whole peppercorns (see notes)
  • 1 tsp. dried thyme (see notes)
  • 1 onion, cut into quarters
  • 2 14 oz. cans low-sodium chicken broth
  • water, if needed to cover the corned beef

Creamy Horseradish Sauce Ingredients:

  • 1/3 cup sour cream
  • 1/3 cup mayo
  • 2 T cream-style horseradish, or more to taste


  1. Remove the corned beef from the package and rinse well with cold water, until all the accumulated gel is removed.
  2. Most corned beef will have a thick layer of fat on one side; trim off most of that fat and then put the beef in the pressure cooker, fat side facing up. You can cut it in half if needed.
  3. Add the bay leaves, peppercorns, dried thyme, and onion pieces to the pressure cooker.  (Or use the spice packet in place of the bay leaves, peppercorns, and thyme if you prefer.)
  4. Pour over the chicken broth, with a little additional water if needed to almost cover the corned beef with liquid.
  5. Set the electric pressure cooker to MANUAL, HIGH PRESSURE, 90 minutes, or you can use 80 minutes if you prefer firmer corned beef that will slice apart easily for sandwiches (For stove-top pressure cooker, bring to high pressure, then reduce heat as low as possible and still maintain high pressure and cook 90 minutes.)
  6. After 90 minutes, use the natural release method to reduce the pressure for 20 minutes, then quick release the remaining pressure.
  7. Remove corned beef to a cutting board and let it rest for a few minutes before cutting.  (If you’re going to cook vegetables in the pressure cooker to go with the meat, cover with foil to keep warm.)
  8. Slice meat and serve hot, with Creamy Horseradish Sauce.

Horseradish Sauce Instructions:

  1. Mix together the sour cream and mayo, then stir in cream-style horseradish to taste. (Some horseradish is much spicier than others, so I’d start by stirring in a small amount of horseradish and tasting the sauce, then adding more until it’s as spicy as you like it.)


You can use the packet of seasonings that come with the corned beef in place of the bay leaves, peppercorns, and thyme if you prefer.

I used a 6 Quart Instant Pot (affiliate link) for this recipe, but you can make this in any electric pressure cooker or a stovetop pressure cooker as well.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Corned beef is definitely a low-carb ingredient, so this should be good for low-carb, Keto, or low-glycemic diets. The original South Beach Diet doesn’t recommend corned beef because of the amount of fat, but if it happens to be St. Patrick’s Day I would certainly have some.
