A creamy milk sauce with a hint of lemon is perfect to coat this delicate yet flavorful fish. Soles have only a few spines so it's an ideal fish for kids too. If you want to simplify it, you can use the same recipe for fish fillets as well.

This elegant fish dish is inspired by traditional European preparations, where milk is used not just for creaminess, but to gently cook and infuse flavor into delicate fish fillets like sole. The result is a moist, melt-in-your-mouth texture and a mild, comforting flavor profile that pairs beautifully with simple sides like potatoes, rice, or greens. It's easy to prepare and ideal for both everyday dinners and special occasions.
The creamy sauce is made with milk and butter and a hint of lemon, and it goes perfect with Sole fish because it's a tender white fish but it also has a distinct flavour of its own which I love. But of course you can also try this recipe with other white fishes if you'd like.

How to clean fresh Sole fish
If you want to simplify this dish you can of course buy Sole fillets, either fresh or frozen (same delicious result), but if you're adventurous and can find fresh Soles in your supermarket or your local fishmonger, here's how to tackle the task of cleaning the fish.
- First thing to do is to remove all the fish scales on both sides, using the apposite fish scaler or a butter knife. Keep the knife flat on the fish and slide horizontally on the opposite direction of the scales.
- Wash the fish to get rid of all the scales you removed, then cut off with scissors the fins on top, bottom and ventral. Cut off the tail too.
- At this point you need to remove the skin. Make a little incision at the bottom of the tail, then grab the skin firmly and pull hard to peel it off. You can use a towel for a firmer grasp, as the skin is quite slippery. Do this on both sides.
- To clean the insides, make a cut on the belly near the head and pull the entrails out with your fingers. (You can also ask your fishmonger to clean the insides for you). Then cut off the head and clean again the fish with running water.
- Now you can choose to either cut fillets out of the fish or use it whole as I did. The Soles only have the central and lateral spines so it's incredibly easy to remove them just before eating.
🍳 Substitutions
- Sole → Use flounder, tilapia, cod, or haddock for a similar mild flavor and flaky texture.
- Whole milk → Substitute with 2% milk, plant-based milk (unsweetened almond or oat), or add a splash of cream for a richer sauce.
- Butter → Use olive oil or margarine for a dairy-free version.
- Flour → Use cornstarch or a gluten-free flour blend if needed.
🥣 Variations
- Cheesy sauce - Stir in a tablespoon of grated Parmesan for a richer flavor.
- Dijon mustard - Add a small spoonful to the milk sauce for subtle tang.
- Poached version - Simmer the sole directly in milk with aromatics, then strain and reduce the milk to make the sauce.
❄️ Storage & Reheating
Fridge: Store leftovers in an airtight container in the refrigerator for up to 2 days. Be sure to cool completely before storing.
Freezer: Not recommended, as the milk sauce may separate when thawed.
Reheating: Gently reheat the fish and sauce together in a pan over low heat, stirring often. Add a splash of milk if the sauce has thickened too much.
💭 Recipe FAQs
Yes, just make sure to thaw them completely and pat them dry before cooking to avoid excess moisture.

Yes! Soft vegetables like peas, cooked leeks, or spinach go well in the milk sauce or on the side.
⭐ Top tip
