What Ingredients are in Mushroom-stuffed Sole Fillets?
Creating this elegant dish requires a carefully selected collection of fresh, quality ingredients that work together to build layers of flavor. Each component plays an important role—from the delicate sole fillets that serve as your protein base to the aromatic mushroom filling and the silky cream sauce that ties everything together. The beauty of this recipe lies in how straightforward the ingredient list is, yet how sophisticated the final result becomes.
Ingredients:
- 4 tablespoons butter
- 1 finely chopped onion
- 12 ounces (350 g) finely chopped mushrooms
- 2 large lemon sole fillets (cut into 4 skinned fillets each)
- 1 cup dry white wine
- 2 teaspoons chopped fresh tarragon
- Salt and black pepper to taste
- 1 cup heavy cream
- A squeeze of fresh lemon juice
- Fresh tarragon sprigs for garnish
When shopping for these ingredients, prioritize sourcing the freshest fish possible from your fishmonger, as the quality of the sole will directly impact the final dish. For the mushrooms, cremini or button mushrooms work beautifully, though you can experiment with other varieties for deeper, earthier notes.
Fresh tarragon is essential rather than dried—the fresh herb provides a delicate anise-like flavor that dried versions cannot replicate. Finally, make certain your heavy cream and white wine are at room temperature before cooking, as this helps them incorporate more smoothly into the dish.
How to Make this Mushroom-stuffed Sole Fillets
- Start by preheating your oven to 350°F (180°C). In a saucepan, melt half of the butter over medium heat, then add the onion and mushrooms. Cook them gently, stirring occasionally, for about 5 minutes until they’re softened and fragrant.
- Take each fish fillet and roll it up carefully with the skinned side facing inward to create neat spirals. Arrange these rolled fillets upright in a shallow baking dish, then spoon the cooked mushroom and onion mixture into the center of each roll.
- Pour the wine around the fish rolls and sprinkle the tarragon over everything. Season generously with salt and pepper to taste. Cover the baking dish with a lid or aluminum foil and place it in the preheated oven. Bake for approximately 15 minutes, or until the fish turns opaque and the flesh flakes easily when tested.
- Once cooked, carefully remove the fish rolls from the baking dish and transfer them to a warmed serving platter to keep them hot. Pour all the cooking juices from the dish into a saucepan and bring to a vigorous boil. Let it bubble away for about 3 minutes until the liquid has reduced by half and intensified in flavor. Stir in the cream and lemon juice, warming everything through gently without boiling. Taste and adjust the seasoning if needed, then pour this silky sauce over the fish. Finish with a garnish of fresh tarragon sprigs before serving.

Mushroom-stuffed Sole Fillets Substitutions and Variations
Once you’ve mastered the classic version, you’ll probably start wondering what else you can throw into this dish, and honestly, that’s where the fun begins. I’d swap the sole for halibut or flounder if I’m feeling adventurous.
The mushroom filling? Try mixing in some finely minced garlic or fresh thyme alongside the tarragon. Want richer flavor. Add a splash of brandy to the cream sauce. Some cooks substitute tarragon with dill or parsley if that’s what’s hanging around in their kitchen.
You could even sneak in some grated Gruyère cheese into the mushroom mixture for unexpected depth. The beauty here is flexibility. This dish won’t judge you for improvising.
What to Serve with Mushroom-stuffed Sole Fillets
How do you round out an elegant plate without overshadowing those delicate, buttery fillets? I’d suggest starting with something simple. A modest green salad with lemon vinaigrette works beautifully, letting the sole shine. Or consider roasted asparagus, which pairs naturally with the tarragon cream sauce.
For starch, I’m thinking buttered new potatoes or a light rice pilaf—nothing heavy that’ll compete for attention. Some people go wild with crusty bread for soaking up that sauce, which honestly, I get. Why waste it?
A crisp white wine like Sauvignon Blanc complements everything perfectly. Keep sides understated though. This dish doesn’t need much else—it’s already doing the fancy dinner work for you.

Why does this dish feel so much more impressive than it actually is? I think it’s because the combination of tender fish, earthy mushrooms, and silky cream sauce tricks your brain into believing you’ve spent hours in the kitchen. Honestly, you haven’t. The magic happens fast—sautéing mushrooms, rolling fillets, simmering everything together. That’s it. What really sells the luxury vibe is plating. Those golden fillets arranged just so, a drizzle of sauce, fresh tarragon on top, and suddenly you’re not eating weeknight dinner—you’re dining. The beauty of this recipe is that it delivers restaurant-quality results without the restaurant-level stress. Your guests won’t know it took maybe thirty minutes total.
