Instant Pot Midwest Pepper Steak
Hearty and filling, your family will love this meal any day of the week! You can serve the steak and vegetables over mashed potatoes and if you want you can even cook the potatoes at the same time using the pot-in-pot method.
This recipe uses flank steak and because of the long cooking time under pressure the flank steak becomes so tender it literally falls apart. You can also make this recipe in the slow cooker using low for many hours. The collagen turns to gelatin and makes the meat fork tender.
Recipe adapted from Culinary Hill.
Ingredients/Substitution Ideas
- Olive oil–of another oil of your choice
- Green bell pepper–or another color of your choice
- Red bell pepper–or another color of your choice
- Onion–I used a yellow onion
- Flank steak–or chuck steak
- Kosher salt
- Red wine vinegar
- Soy sauce–I used low sodium soy sauce
- Honey
- Brown sugar
- Sesame oil
- Black pepper
- Garlic–from the jar or fresh
- Cornstarch–this is optional
Steps
- Make the sauce: In a small bowl whisk together the vinegar, soy sauce, honey, brown sugar, sesame oil, pepper and garlic. Set aside.
- Sauté vegetables: Turn Instant Pot to sauté setting. When display says HOT add in 1 ½ tsp of oil, bell peppers and onions. Sauté until softened. Transfer vegetables to a plate.
- Brown the meat: Sprinkle the steak with the kosher salt. Add remaining 1 ½ tsp of oil into Instant Pot. Brown for 2 minutes on each side.
- Deglaze the pot: More meat to the side. Pour in the soy sauce mixture and scrape bottom of pot so that nothing is sticking. Turn off sauté setting.
- Pressure cook: Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 45 minutes. When time is up let the pressure release naturally (about 10-15 minutes). Remove the lid.
- Slice steak: Move steak to a cutting board and slice or shred.
- Thicken sauce: Stir 1 Tbsp of cornstarch together with 1 Tbsp of water until smooth. Turn Instant Pot to sauté setting. Stir the cornstarch slurry into the pot to thicken the sauce.
- Serve: Stir the meat and vegetables into the pot. Salt to taste, if needed. Serve and enjoy.
Notes/Tips
- Serve with mashed potatoes, egg noodles or rice. You can even cook potatoes at the same time using the pot-in-pot method. Place a tall trivet in the bottom of the pot around the meat. Then place a pan on top of the trivet. Pressure cook as directed in the recipe. Add some washed whole potatoes into the pan. Once meat has cooked transfer the potatoes to a bowl and mash. Stir in some milk, butter, salt and pepper.
- This recipe can be gluten-free if you use a gluten-free soy sauce.
- I used my 6 quart Instant Pot*. You can also make this in a 3 or 8 quart pot. Although if you use a 3 quart pot you will not have room to cook potatoes at the same time.
- Store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.

I like your blog, but i’m not sure that I plan on to keep visiting it in future. You’ve got far too many advertisements and all these crazy ads that don’t relate to me, in the least. You need to get serious and find a better way to make revenue. This really makes me think less of you and your endeavors.
She could charge for each recipe but many of us like to share recipes for free, and this is the only way to do that.
Well, a ridiculous number of ads is not the only way to get money here & there. She could have a Donation button — if you like the recipe then contribute a little. Or, start Patreon and have subscribers to her content. Maybe, even start a Youtube channel and get subbers & make money that way. Write a cookbook and sell it. But, her website has more ads and distractions than I have ever seen. I’m counting 1, 2, 3 … no yeah, 12 different ad pop-ups.
Don’t you think that’s a little much. She’s got good recipes, but even my wife says she stopped coming here because all of this crap that is detracting from her “good works”.
From my side, I’d be happy to pay her something for each recipe. Or, even pay a monthly subscription of a small amount. But dealing with all these ads — just really detracts from the service / what she is trying to provide to people.
I like her Blog so much that I’d be willing to pay a small amount per recipe or for a yearly subscription. Just this many ads, is really detracting from the Service that she is trying to provide to people. I just don’t understand why someone with as much talent and content as she has, is willing to put all of these useless ads on her website. Much better ways to get compensated than this markarkey.
I will work on a subscription site that has no ads! I’ll let you know when it becomes available.
