Garlic Balsamic Instant Pot Flank Steak

Greg and I both were in awe of how amazing this Instant Pot flank steak turned out! It was incredibly flavorful and tender. The balsamic garlic sauce was spot on too. I highly recommend cooking a flank steak in your Instant Pot. Give your grill a break and try out your pressure cooker this week!

Why flank steak works in the pressure cooker and slow cooker

Usually flank steak is cooked on the grill. But did you know that you can also pressure cook or slow cook it and get great results? Flank steak is best either hot and fast (grill) or braised. With the pressure cooker or slow cooker you can braise the steak until it breaks down the connective tissues and tenderizes. That's why the recipe calls for a fairly long cooking time, to break down that connective tissue.

How to make flank steak in the Instant Pot

1. Heat your Instant Pot by turning on the saute setting.
2. Season both sides of the flank steak (or you can use a skirt steak).
3. When Instant Pot says HOT add in 2 Tbsp of oil and then place the steak in the pot. Brown on each side of the steak for 2 minutes.
4. Deglaze the pot by moving the steak out of the way and pouring in some broth to scrape the bottom of the pot.
5. Cover the Instant Pot and pressure cook for 50 minutes with a natural pressure release.
6. Move steak to cutting board and let sit for 5-10 minutes and then slice against the grain.

How and why to slice across the grain

In the context of meat, the grain refers to the direction that the muscle fibers are aligned.

In the photo of flank steak above, you can see that the fibers run horizontally from side to side. The cut of meat isn't the only determinate in how tender it is, it's also HOW you cut the meat. When you cut against the grain you cut through the fibers and shorten them. This makes the meat easier to chew.

Description

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!

---

• 2 Tbsp canola oil
• 1 (2 pound) flank or skirt steak
• 1 tsp kosher salt
• 1 tsp black pepper
• 1/2 cup chicken or beef broth
• 2 Tbsp balsamic vinegar
• 2 Tbsp rice vinegar
• 1 Tbsp Dijon mustard
• 1 Tbsp minced garlic

---

1. 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.
2. Add in vinegars, mustard and garlic. Place the steak down into the liquid.
3. 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.
4. 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!

Notes

I used my 6 quart Instant Pot Duo 60 7 in 1*. Make this in your 3 or 8 quart pot with no changes. For 3 quart pot you may need to slice steak in half to fit.

Slow Cooker Instructions: Heat pan over medium high heat. Add in oil. Press kosher salt and pepper on each side of the steak. Brown steak on each side for 2 minutes. Add steak to slow cooker. Stir rest of ingredients together and pour over the top of steak. Cover and cook on low for 6-8 hours.
