1-First step: Get everything ready before you turn on the stove Start by thawing the shrimp if they are frozen. This recipe moves quickly, so it helps to have every ingredient chopped, measured, and ready before the pan gets hot. Cut the broccoli or broccolini into small florets, thinly slice the bell peppers, slice the shiitake mushrooms if you are using them, and cut the green onions. Pat the shrimp dry with paper towels. This matters because dry shrimp sear better and cook with a nicer texture. If you are serving this shrimp stir fry with rice or noodles, cook those separately now so everything is ready at the same time.

2-Second step: Whisk the sauce until smooth In a small bowl, whisk together the soy sauce, water, rice vinegar, sugar, miso, cornstarch, and garlic powder. Stir until the sauce looks smooth and the miso is mostly dissolved. If you want a gluten-free version, use tamari or coconut aminos instead of soy sauce. The sauce should look thin at this stage. It will thicken later when it hits the heat. If you like a little spice, you can add red pepper flakes to the sauce, but keep the base recipe as written if this is your first time making it.

3-Third step: Cook the vegetables first Heat 2 tablespoons of sesame oil in a large 12-inch skillet or bigger over medium-high heat. When the oil shimmers, add the broccoli, bell peppers, and mushrooms. Cook for 5 to 6 minutes, stirring often, until the vegetables are crisp-tender. They should still have some bite, since they will cook a little more later. Once the vegetables are ready, transfer them to a bowl. This keeps them from getting too soft while you cook the shrimp. If you want extra vegetables, you can add carrots, zucchini, snap peas, or any other quick-cooking vegetables you enjoy.

4-Fourth step: Cook the shrimp with ginger and green onions Add the remaining 1 tablespoon of sesame oil to the same skillet. Then add the shrimp, green onions, and minced ginger. Cook for 1 to 2 minutes, turning the shrimp once so both sides cook evenly. The shrimp should be almost opaque but not fully done yet. Do not walk away during this part. Shrimp cooks fast, and overcooking can make it rubbery. Medium shrimp, usually 41 to 50 per pound, work especially well because they stay tender and finish quickly. If you are using another protein in a variation, the cook time will change based on what you choose.

5-Fifth step: Add the sauce and finish the dish Return the cooked vegetables to the skillet, then pour in the sauce. Reduce the heat to low and stir everything together gently. The sauce will thicken as it warms, coating the shrimp and vegetables in a glossy finish. This usually takes just a minute or two. Taste the stir fry and adjust only if needed. If you want a sweeter sauce, add a little more sugar. If you want more saltiness, a small splash of soy sauce can help. Serve right away while everything is hot and crisp.

6-Final step: Serve and enjoy Spoon the shrimp stir fry over rice, noodles, or your favorite grain. Keep the starch on the side if you are planning to store leftovers, since that helps the texture stay better. A sprinkle of extra sliced green onions on top gives the dish a fresh finish.
