Benefits
Instant Pot Pepper Steak offers a balanced combination of protein, vegetables, and comforting flavor. Flank steak provides high quality protein along with iron and zinc, which support energy levels and muscle health. Bell peppers add vitamin C, antioxidants, and natural sweetness that brightens the dish. Ginger contributes digestive support and a warm aromatic note that enhances savory sauces.
This recipe works well for people who want a filling meal without deep frying or heavy cream based sauces. Pressure cooking allows the beef to become tender quickly while retaining moisture, which helps reduce the need for excessive oil. The sauce thickened with cornstarch creates a glossy texture without relying on butter or cheese.
For people watching sodium intake, using coconut aminos instead of traditional soy sauce helps keep flavors rich while staying gentler on salt levels. This dish is also naturally dairy free and can be paired with rice alternatives like cauliflower rice for lighter meals. Instant Pot Pepper Steak is not ideal for those avoiding red meat, but it can be adapted using turkey or plant based strips if desired.

1 and a half tablespoons rice vinegar
2 and a half teaspoons freshly grated ginger
1 tablespoon packed brown sugar
1 quarter teaspoon ground black pepper
2 and a half tablespoons cornstarch
3 tablespoons water

Step by Step
Begin by setting the Instant Pot to the saute function. Add the olive oil and allow it to heat until it shimmers slightly. This step helps build flavor at the base of the pot and prevents sticking later.
Add the sliced bell peppers to the hot oil. Stir gently and cook for two to three minutes until the peppers are just tender but still crisp. You want them vibrant and slightly firm because they will cook again later. Remove the peppers from the pot and set them aside on a plate.
With the pot still on saute, pour in the water. Use your spoon to scrape up any flavorful bits from the bottom. Add the Coconut Secret Coconut Aminos, Big Tree Farms Coconut Aminos, rice vinegar, grated ginger, brown sugar, and black pepper. Stir well until the sugar dissolves and the mixture looks evenly blended.
Add the sliced flank steak to the pot. Use the spoon to separate the slices so they do not clump together. Make sure all pieces are lightly coated in the sauce. Turn off the saute function.
Secure the lid on the Instant Pot and set the valve to sealing. Select high pressure and set the cooking time to ten minutes. The Instant Pot will take several minutes to come to pressure before the timer begins.
While the beef cooks, prepare the thickening mixture. In a small bowl, whisk the cornstarch with three tablespoons of water until completely smooth. This slurry will give the sauce its classic pepper steak texture.
Once the cooking time ends, carefully perform a quick release by turning the valve to venting. Avoid letting the pot sit, as extended heat can overcook the beef and change its texture.
Open the lid once it is safe. Stir the beef and sauce gently, allowing some steam to escape. Pour in the cornstarch slurry while stirring continuously. The sauce will begin to thicken within seconds.
Add the cooked bell peppers back into the pot. Set the Instant Pot to saute again and cook for about one minute, stirring to coat everything evenly. Turn off the heat once the sauce is glossy and the peppers are heated through. Serve immediately.
Storage
Instant Pot Pepper Steak stores well and makes excellent leftovers. Allow the dish to cool to room temperature before transferring it to an airtight container. Store in the refrigerator for up to four days. The flavors often deepen overnight, making it even more satisfying the next day.
For freezing, place cooled pepper steak into freezer safe containers or heavy duty freezer bags. Remove as much air as possible to prevent freezer burn. Freeze for up to two months. Thaw overnight in the refrigerator before reheating.
To reheat, warm gently on the stovetop over medium low heat or use the microwave in short intervals, stirring between each. Add a small splash of water if the sauce has thickened too much. Avoid overheating to keep the beef tender.
Variations and Substitutions
You can easily customize Instant Pot Pepper Steak to suit different tastes. Swap flank steak with top sirloin or skirt steak for similar tenderness. For a lighter option, thinly sliced turkey breast works well with the same sauce.
Vegetable variations include adding sliced onions, snap peas, or mushrooms. These should be added with the bell peppers to maintain texture. For extra heat, a pinch of crushed red pepper flakes or fresh sliced chili can be stirred into the sauce.
If you prefer a sweeter profile, increase the brown sugar slightly or add a teaspoon of honey. For a deeper savory note, a small spoon of beef broth concentrate can be added to the liquid mixture.
Tips and Tricks
Slice the beef against the grain. This shortens the muscle fibers and ensures tender bites. Use a very sharp knife for clean, even slices.
Do not overcrowd the pot when sauteing the peppers. Cooking them briefly keeps their color and crunch intact. Removing them early prevents sogginess.
Always perform a quick release. Allowing pressure to release naturally can cause the beef to break down too much and lose its steak like texture.
Stir the cornstarch slurry again just before adding it. Cornstarch settles quickly and needs to be fully dissolved to avoid lumps.
If the sauce becomes too thick, add a tablespoon of water at a time while stirring until it reaches your preferred consistency.
Notes
Choose fresh bell peppers with firm skins and bright color. A mix of green, red, and orange peppers adds visual appeal and balanced sweetness.
Fresh ginger provides the best aroma and flavor. If using pre grated ginger, reduce the amount slightly as it can be more intense.
Keep the beef slices uniform in thickness. Even slices cook at the same rate and prevent chewy pieces.
Serve the dish immediately after thickening the sauce. Waiting too long can cause the sauce to continue thickening as it cools.
Serving Suggestions
Serve Instant Pot Pepper Steak over steamed jasmine rice, brown rice, or cauliflower rice. It also pairs well with noodles or alongside simple stir fried vegetables for a complete meal.
