Instant Pot Beef Stew

I wanted to make beef stew and make sure that Henry could have it as well as make sure it is something that mostly everyone will enjoy (once I convince the kids to try it).  I found a couple of recipes that looked good, mostly this one from Pinch of Yum, but it did not have potatoes, so I took ingredients from here and here and put it together to make a hybrid version.  Takes approximately 90 minutes start to finish.  It was a hit with everyone!

Instant Pot Beef Stew

2 LB beef chuck roast - cut into 1-2" chunks
1 onion - diced
2 stalks celery - sliced
1/2 bag baby carrots - sliced
1 LB potatoes (5 medium) - cubed
2 cloves garlic - minced
8 oz can tomato sauce
2 1/2 cup beef broth
1 tsp salt
1 tsp italian seasoning
2 T brown sugar
2 T cornstarch
1/4 cup water

Place everything except the cornstarch and water in the Instant Pot. Cook on high pressure for 35 minutes, then let it release naturally for 10 minutes.  Release the rest of the steam, then mix cornstarch with the water and add to the broth to thicken.  It takes about 30 minutes to come up to pressure.
