Turn ordinary oyster mushrooms into something truly special with this crispy yet hearty salad. Warm pan-fried mushrooms with sharp cheddar and a honey-mustard vinaigrette add savory depth and restaurant flair to familiar garden greens—perfect for impressing guests or treating yourself to a luxurious lunch. Every bite offers a charming contrast of crunchy mushrooms and cool vegetables, tied together with rich aged cheese.
I still remember the first time I served this at a family dinner; the platter disappeared in minutes and now it is always requested for special gatherings.
Ingredients
- Mixed salad greens: such as arugula or spinach provide a fresh base and work well with savory mushroom flavors. Choose leaves that are vibrant and perky.
- Fresh oyster mushrooms: are key for a tender bite and unique delicate flavor. Pick clusters with no dark spots or sliminess.
- Corn flour or cornstarch: helps create an airy and irresistible crunch on the mushrooms.
- Clarified butter: offers clean flavor and a golden sear. Make your own by gently melting butter and pouring off the clear fat.
- Hard-boiled eggs: add creaminess and protein. Use eggs with deep yellow yolks for best color.
- Cherry tomatoes: bring juicy brightness and a touch of sweetness to the salad.
- Walnuts: add a warm crunch and earthy taste. Toast just before using for big impact.
- Aged cheddar cheese: provides sharpness and depth. Always grate it yourself for better melt and texture.
- Dijon mustard: for the vinaigrette brings bold flavor without too much heat. Look for smooth, creamy consistency.
- Balsamic vinegar: creates a sweet-tart backbone in the dressing. Good aged balsamic will give more complexity.
- Fresh lemon juice: freshens and balances out sweetness.
- Honey: rounds out acidity and brings natural sweetness and gloss.
- Extra virgin olive oil: gives the vinaigrette body and richness. Choose cold-pressed with a fruity scent.
- Salt and black pepper: for seasoning. Freshly cracked black pepper gives the dressing extra flavor.
Step-by-Step Instructions
- Clean and Cut the Mushrooms:
- Begin by gently wiping oyster mushrooms with a damp paper towel to remove dirt. If the mushrooms are large, cut them into smaller pieces. Keep smaller ones whole to preserve their unique shape.
- Dust and Fry the Mushrooms:
- After cleaning, toss the mushroom pieces lightly in corn flour or cornstarch until just coated. Shake off any excess flour so the coating stays thin and crisp. Heat clarified butter in a skillet over medium-high until shimmering but not smoking. Add mushrooms in a single layer and fry without crowding. Cook each side for about three to four minutes until golden and crispy all over. Remove to a towel-lined plate to cool.
- Prepare Eggs and Walnuts:
- While mushrooms fry, place eggs in a saucepan filled with cold water. Bring to a gentle boil and cook for ten minutes. Transfer cooked eggs to an ice bath, then peel and slice or quarter. Toast walnuts in a dry pan for a few minutes until fragrant and lightly colored, watching closely so they do not burn.
- Make the Honey-Mustard Vinaigrette:
- In a small bowl, combine Dijon mustard, balsamic vinegar, lemon juice, and honey. Whisk until smoothly blended. Slowly pour in olive oil while whisking constantly. The mixture should emulsify into a creamy dressing. Season with salt and freshly ground pepper to taste.
- Assemble the Salad:
- Tear salad greens and arrange on a serving platter or plates. Place egg quarters evenly around the edge. Scatter with halved cherry tomatoes. Top with warm mushrooms and sprinkle with toasted walnuts and grated aged cheddar. Drizzle the dressing evenly over the salad just before serving.

Walnuts are my favorite part in this salad because their earthy crunch perfectly balances the creaminess of the cheddar and richness from the eggs. When we made this for a holiday dinner, my kids loved picking out the biggest mushroom pieces while my spouse kept sneaking crunchy walnuts—creating some funny family rivalry over the salad bowl.
Storage Tips
Though best enjoyed fresh, you can prep several items in advance. Hard-boiled eggs can be kept in their shells in the fridge for up to a week. Vinaigrette stores well for three days in a sealed jar. Wait to fry mushrooms and combine salad just before serving for maximum crispness.
Ingredient Substitutions
Try pecans or hazelnuts if you do not have walnuts. Shiitake or king oyster mushrooms can also replace oyster mushrooms for a different twist. The cheese is flexible—gruyere brings extra creaminess or try a mild blue cheese for bolder flavor.
Serving Suggestions
Serve this salad as a stand-alone lunch with crusty bread. For dinner, pair with grilled chicken or roasted vegetables on the side. It works beautifully as a starter course for holiday or dinner parties because it looks so colorful on a large platter.

Cultural and Historical Context
Oyster mushrooms have long been cherished in Eastern European dishes and modern vegetarian cuisine alike, thanks to their meaty texture and mild, woodsy flavor. This salad brings together classic ingredients with a twist by combining crispy hot mushrooms and tangy cheese—a restaurant move I first found in a small French bistro years ago before bringing it to my own kitchen.
