The most tender and delicious Instant Pot steak ever! Flank steak or skirt steak is pressure cooked in a garlic balsamic marinade sauce and then sliced and served. No knives needed to cut this steak!

Instant Pot Flank Steak

Tbsp canola oil

(2 pound) flank or skirt steak

tsp kosher salt

tsp black pepper

broth

Tbsp balsamic vinegar

Tbsp rice vinegar

Dijon mustard

Tbsp minced garlic

Turn Instant Pot to saute setting. Press kosher salt and pepper on each side of the steak. When the display says HOT add in the oil and swirl it around. Brown the steak in the oil for 2 minutes on each side. Move the steak to the side and deglaze the pot with the broth. 

Add in vinegars, mustard and garlic. Place the steak down into the liquid.

Cover the Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 50 minutes. When the time is up let the pot sit for 15 minutes and then move the valve to venting to release any remaining pressure. Remove the lid.

Use tongs to place steak on a cutting board. Let it sit for 5 minutes. Then slice the steak against the grain. Drizzle juices from Instant Pot over the steak. Eat and enjoy!

you pretty much stated how I feel about the recipe I tried last night. I didn't use the broth, etc. as marinade and as a sauce isn't particularly good. Really mincing the garlic very finely would help.
The main thing is that the meat, while totally tender, is well done. What we like best is a grilled flank steak where the meat has some charring. Yes, preparing a marinade and having the meat sit for some hours or overnight does take time. The actually cooking time is not more than 10 min. or so (depending on how large the piece is). This recipe takes a total of well over an hour.
I imagine that doing a pot roast, stew, etc. would be perfect but I wouldn't do a flank steak again.

I love this recipe. I use the leftovers, if any, for so many other dishes. I am diabetic and most of the recipes I get from here fit into my menus. Sometimes I tweak an ingredient or maybe the pastas or rice but the base recipes are delicious. My favorite way to use leftover flank steak in the next day on a big salad with a touch of blue cheese. I am going to try this recipe with chicken also.

We got a pre-seasoned Korean Barbecue recipe flank steak from Costco and I followed your cooking instructions...
Holy Yummy Goodness, Batman! It was so delicious I kinda wanna propose to you now!
(Please don't tell my husband! He'd be jealous as he feels the same way! 😂)

I have made this recipe both in an instant pot and slow cooker and both times both my hubby and I really enjoyed it! Thanks!

Holy moly! This was so good! My store almost never has flank steaks, so had to wait until they did. This was beyond tender and so much good flavor! Thank you so much for this recipe!

Loved this recipe.  So easy to make.  The sauce is perfect, I managed to save a little for lunch. About 1/4 of my saved Pinterest recipes are yours.

I am so happy I found this recipe!! I did not have  rice vinegar so I used apple cider vinegar. I also mixed up some water and cornstarch and added it to the marinate and made it more of a glaze to put over the meat when it was done. 
 It turned out great!!  Very easy and delicious.  Thank you

This flank steak was so easy to make and so good! I was skeptical when it said no knife needed to cut and it was so fall apart tender that it really did not need a knife. This will replace my other flank steak recipe that uses a rub. This is so much better!

Absolutely delish
I had a Korean (flavored) packaged flank steak from Costco and I am currently without an oven so I tried this recipe and it was easy and fantastic. I served it with Pepperonata (sautéed multi colored bell peppers, onion, garlic). It all made for a beautiful plate

Followed directions as stated and it came out perfectly. Only thing I changed was the steak. I used sirloin because I cannot find the flank or skirt steak. Either way it is fall apart tender. My husband,12 y/o finicky daughter and 15 y/o son absolutely devoured it! Thanks for an easy yet delicious recipe to cycle on busy weeknights!!

It was awesome. I did a skirt steak and followed the recipe exactly - BUT I charred the exterior on the hot grill front and back and then sliced it into pieces to add to the insta pot. I did 38 minutes in the broth and seasonings as you laid out and then after removing the meat (to slice across grain) I reduced the broth and garlic mix; to a delicious silky sauce. It was so tender and delicious....I sneaked back in to have some cold slivers leftover.... this is a KEEPER!!!!

I made this last night and it was absolutely delicious. Couldn't be easier to throw together. I tossed in some mushrooms, on a whim, since I had 'em, and they were a tasty compliment. I've never made a flank steak as stew meat, so this was a first, and I was surprised at how truly wonderful it was. Thanks for the recipe. It's a keeper! &lt;3 I&#039;m now going to mess with it and try variations. I think sautéing onions, after browning the meat, then deglazing and cooking all together could work, too. I&#039;m gonna find out. :)

At what point did you toss in the mushrooms?

Thank you foreceive recipe! It was awesome, really delicious! 

Quick question. Do you think I would have to change much if I coojed 2lbs of Flank instead of the 1 shown in the recipe?

I made this tonight! It was easy and so good! I thought I had rice vinegar but alas, did not, so I subbed red wine vinegar and it came out fantastic. Paired it with a beef rice and vermicelli with a hint of soy sauce. It went together great! Thank you!

THIS WAS AMAZING! I made it with flank steak which made it so it was stringy pieces of meat but it was fabulous. Turns out I didnt have rice vinegar so I substituted with the red wine vinegar and sugar I didn't have balsamic! So I used apple cider vinegar and sugar AND I also didn't have dijon mustard, so I used regular mustard with white wine vinegar...divine!!! Even my 2 year old LOVED it!! (and he basically eats chicken nuggets and cheese for everything ;D )We literally ate the leftovers for dinner the next night and lunch for 2 days!! SOO good...next time I made it I did the same thing but with dijon mustard and I also added red potatoes and carrots and celery to the dish...I just love this cut of meat (flank with the tangy vinegar tastes) THANK YOU SO MUCH! I am brand new to insta Pot and this was the first recipe I did and it blew my family away!! I am for sure "pinning" the recipe for a go to meal! Thank you!

Super easy, and what a difference from pan searing! It shreds into strings but I cut it across the grain and it made the best taco meat.  Super tender.  I’ll have to make more next time so we can try a potato hash.  Thanks for this recipe!
