Substituting for olive oil is easy to do. If you want an oil that matches it closely in flavor, try avocado oil. Otherwise, use good ol’ vegetable oil.
If king oyster mushrooms are unavailable, use shiitake mushrooms or button mushrooms.
Broth made from vegetables or chicken: Substitute with broth made from mushrooms to attain a more potent umami taste.
Soy sauce: For a gluten-free option, use tamari; for a lower-sodium alternative, use coconut aminos.
Oyster sauce: If you do not have this sauce on hand, you can use hoisin sauce for sweetness or vegetarian oyster sauce for a plant-based alternative.

Pro Tips

1. Maximize Mushroom Flavor To enhance the umami flavor, allow the mushrooms to brown properly by not overcrowding the skillet. Cook them in batches if necessary to ensure they get a nice golden crust.

2. Garlic Infusion Infuse the olive oil with garlic flavor by adding the minced garlic slightly earlier in step 3, then quickly adding the mushrooms to avoid burning. This will give the oil a better depth of flavor.

3. Broth Enhancement Use homemade or low-sodium broth to better control the saltiness of the dish. Consider simmering the broth with a bay leaf or some thyme for added flavor before adding it to the mushrooms.

4. Cornstarch Slurry Tip Mix the cornstarch and water thoroughly until it’s completely dissolved before adding it to the skillet to prevent lumps. Make sure to stir constantly once added to achieve a smooth sauce.

5. Flavor Boost For an extra depth of flavor, add a splash of sesame oil right before serving. It will provide a subtle nutty aroma that complements the dish perfectly.
