Steamed Egg Mushroom Recipe: Silky Custard With Earthy Depth

This dish transforms humble ingredients into something extraordinary. The secret is in the steaming, which creates a silky egg custard that pairs perfectly with earthy mushrooms.

I’ve perfected this method to ensure the eggs stay tender and the flavors meld beautifully. Simple, precise, and always impressive.

Ingredients for Steamed Egg Mushroom

Humble ingredients transform into silky egg custard paired with earthy mushrooms through precise steaming.

The eggs are the foundation here. Use the freshest large eggs you can find—older eggs lose structure during steaming. Cremini mushrooms offer the best earthy depth, but shiitake or white button work too. For the broth, Kettle & Fire or Pacific Foods offer consistent quality. Avoid high-sodium versions as they can overpower the delicate custard.

No Shaoxing wine? Dry sherry at equal amount is the closest substitute. For a non-alcoholic option, additional broth with a dash of rice vinegar mimics the acidity. White pepper is traditional (it doesn’t discolor the custard), but black pepper works in a pinch. If using vegetable broth for a vegetarian version, look for low-sodium varieties.

The custard keeps 2-3 days refrigerated but is best served fresh. Reheat gently by steaming again—microwaving can make it rubbery. Mushrooms can be prepped 1 day ahead and stored in the fridge. Always bring eggs to room temperature before starting for even cooking.

Step-by-Step Instructions for Steamed Egg Mushroom

Master this technique and you’ll deliver a velvety custard with rich umami depth every time.

Step 1: Prepare the Mushroom Mixture

Heat the 1 tbsp neutral oil in a large skillet over medium-high heat. Add the 1 lb cremini mushrooms and sauté for 5-6 minutes until they release their moisture and turn golden brown at the edges.

Add the minced 3 cloves garlic cloves and cook for 30 seconds until fragrant. Stir in the 2 tbsp soy sauce, 1 tsp sesame oil, and 1 tbsp Shaoxing wine, then remove from heat. This builds a deep, savory base for the custard.

Step 2: Create the Egg Custard Base

In a large bowl, whisk the 6 whole large eggs until smooth and slightly frothy. Gradually pour in the 1.5 cups low-sodium chicken broth while whisking constantly to maintain a uniform texture.

Add the 1 tsp cornstarch, 0.5 tsp salt, and 0.25 tsp ground white pepper, whisking until fully incorporated. The cornstarch ensures a silky, stable custard that holds its shape when steamed. Strain the mixture through a fine-mesh sieve for an ultra-smooth consistency.

Step 3: Combine and Transfer to Steaming Setup

Gently fold the sautéed mushroom mixture into the egg custard, ensuring even distribution without deflating the egg foam. Pour the combined mixture into a heatproof dish that fits inside your steamer, such as a shallow ceramic or glass baking dish.

Cover the dish loosely with aluminum foil, poking a few small holes to allow steam to escape. This prevents condensation from dripping back into the custard, which could create watery spots.

Step 4: Steam to Silky Perfection

Bring the 1 cup water to a boil in a large pot fitted with a steamer basket or rack. Place the dish in the steamer, ensuring it sits above the water level. Cover the pot with a tight-fitting lid and steam over medium heat for 15-18 minutes.

Check for doneness by gently shaking the dish—the custard should wobble slightly in the center but not be liquid. The edges will appear set and slightly puffed. Over-steaming will cause the custard to become dense, so monitor closely.

Step 5: Finish and Garnish

Carefully remove the dish from the steamer and let it rest for 2-3 minutes to firm up slightly. Slice the 3 whole green onions thinly, separating the white and green parts, and scatter them over the top for a fresh, vibrant finish.

Serve immediately while still warm, spooning portions into bowls. The custard should be glossy and smooth, with the earthy mushrooms suspended throughout. The texture should be tender yet firm enough to hold its shape.

Storing and Reheating Leftovers

Refrigerator Storage

Let this creation cool completely at room temperature for no more than 2 hours before refrigerating. Store in an airtight container for up to 3 days. The custard texture is best within 24 hours of cooking. ❄️

Freezer Storage

For longer storage, freeze individual portions in quart-sized freezer bags with all air removed. It keeps well for up to 1 month without texture loss. Thaw overnight in the fridge before reheating.

Steamer Reheating

Gently reheat by steaming again for 8-10 minutes until reaching 165°F internal temperature. This preserves the silky texture better than any other method. Add a splash of broth if it appears dry.

Microwave Option

For quick reheating, cover with a damp paper towel and microwave at 50% power for 1-2 minutes. Stir and check temperature, repeating in 30-second intervals until warm. 🔥

Serving Leftovers

If the custard separates slightly during storage, whisk it gently before reheating. The mushrooms will absorb some liquid, plumping up nicely when warmed. Garnish with fresh green onions after reheating.
