Fry the tofu - 3 ways: Drain the tofu and cut it up into bite-size pieces. Place them on paper towels and pat them dry to drain more water out - the crispier it'll get when fried or baked.Air Fryer – – Grease your air fryer basket with cooking spray and place the tofu pieces in a single layer making sure not to overcrowd them. Depending on the size of your air fryer, you may have to do it in separate batches. Cook at 400◦F for 10-12 minutes until browned and crispy. Shake the pan halfway through to ensure even cooking. Oven – Generously grease your baking sheet and spread out the tofu pieces. Bake at 400° F for 20 minutes total until crisp and nicely browned. Flip them halfway through to crisp the other side.Wok or Pan – Set your wok or pan to medium-high heat and add oil to cover the bottom. When the oil is hot and ready, add the tofu in a single layer. Do not overcrowd so they don't steam. Let them brown and crisp for about 2 minutes before flipping, or they will stick to the pan. Brown the other side for the same amount of time.
Prepare the rest of the ingredients: Wash the asparagus, line them up on a cutting board, and slice off the woody ends where the green starts to fade into white. Cut them diagonally into 2-inch sections. Cut the scallions the same way. Mince the garlic and grate (or mince!) the ginger.
Make the sauce: In a small bowl or cup, stir the cornstarch, Chili Garlic Sauce, sugar, Shaoxing wine, soy sauce, and water.
Stir-fry: Set your wok or pan to medium-high heat and add the oil. Add the ginger and garlic, cook for about 30 seconds. Careful not to brown them, or they'll be burnt when the whole thing is done. Add the scallions and the asparagus, cook for 2 minutes (1 minute for thin asparagus). Keep them moving in the pan, so they don't burn. Add the tofu and mix them up. When you add the sauce, it will immediately bring the temperature down so turn up the heat a notch. Pour the sauce over and keep stirring for about a minute until bubbling and thickened. Add the sesame oil and some ground pepper. Give it a taste and adjust accordingly. Turn off the heat.
Serve: It's best served with rice or noodles and enjoyed while it's hot!
