1-First step: Prep the ingredients Start by patting the shrimp dry with paper towels. This helps them sear instead of steam. Slice the bell peppers into thin strips, cut the broccoli or broccolini into bite-sized pieces if needed, slice the mushrooms, and thinly slice the green onions. Mince the ginger if it is not already prepared. In a small bowl, whisk together the soy sauce, water, rice vinegar, sugar, miso, cornstarch, and garlic powder until the mixture looks smooth. The sauce should be ready before the shrimp hits the pan, because the cooking goes quickly once you start. If you are cooking for picky eaters, you can keep the vegetables in larger pieces for a milder bite.

2-Second step: Heat the pan Set a large skillet or wok over medium-high to high heat. Add 2 tablespoons of the sesame oil and let it warm until it shimmers. A hot pan helps create the best texture for shrimp stir fry, especially if you want the shrimp to stay juicy and the vegetables crisp-tender. Use a large pan if possible. If your pan is small, cook the shrimp in batches so they are not crowded. Crowding causes steaming, which softens the shrimp too much and keeps the vegetables from browning nicely.

3-Third step: Cook the shrimp Add the shrimp in a single layer and cook for about 1 to 2 minutes per side, just until they turn pink and opaque. Remove them from the pan as soon as they are done. Shrimp cooks very fast, and taking it out early keeps it tender. If you are using frozen shrimp that has been thawed properly, this step works the same way. The key is to avoid overcooking. Medium shrimp are a great size here because they cook evenly and mix well with the vegetables.

4-Fourth step: Stir fry the vegetables Add the remaining 1 tablespoon sesame oil to the pan. Toss in the broccoli, bell peppers, shiitake mushrooms if using, and ginger. Stir fry for about 3 to 5 minutes, depending on how tender you like your vegetables. The broccoli should stay bright green, and the peppers should still have a little crunch. If the pan seems dry, add a splash of water to help the vegetables steam just a little while they cook. This is helpful if you like softer broccoli in your shrimp and vegetable stir fry. Keep stirring so nothing sticks or burns.

5-Fifth step: Add the sauce Give the sauce another quick whisk and pour it into the pan. Stir constantly as it bubbles and thickens. The cornstarch or arrowroot powder should thicken the sauce within about 30 seconds to 1 minute. Once the sauce looks glossy, it is ready. At this point, taste a vegetable or a little sauce if you want to check the balance. If you prefer a sweeter stir fry, the sugar in the sauce already handles that. If you want more brightness, a small splash of rice vinegar can help.

6-Sixth step: Return the shrimp Add the shrimp back into the pan and toss everything together until the shrimp and vegetables are coated in sauce. Stir just long enough to warm the shrimp through, about 30 seconds to 1 minute. You want the shrimp hot, but not cooked again for too long. This is the moment when the shrimp stir fry starts to smell amazing. The ginger, miso, sesame oil, and soy sauce create that classic savory aroma that makes everyone wander into the kitchen asking when dinner is ready.

7-Final step: Finish and serve Turn off the heat and sprinkle the sliced green onions over the top. Serve the shrimp stir fry right away while it is hot and glossy. It is great on its own for a lighter meal, but it also pairs well with rice, noodles, or cauliflower rice.
