Best Flounder Milanese Recipe

I’ve always loved the simplicity of Italian cooking. There’s something special about taking a few good ingredients and turning them into dinner without much fuss. That’s exactly what this flounder milanese brings to the table – it’s the kind of meal I make when I want something that feels a bit fancy but doesn’t require hours in the kitchen.

When my kids were younger and getting them to eat fish was a challenge, this recipe became my secret weapon. The crispy coating makes it familiar enough for picky eaters, while the light, flaky fish underneath keeps the grown-ups happy. I usually serve it with a squeeze of lemon and whatever vegetables I have in the fridge, and dinner’s ready in under 30 minutes.

If you’ve never tried making milanese at home, don’t worry – it’s actually one of the easiest Italian dishes to master. And while veal or chicken might be more common, flounder works perfectly and costs less at the grocery store. Trust me, this is the kind of recipe you’ll want to keep in your back pocket for busy weeknights.

What Kind of Flounder Should I Use?

When shopping for flounder, you’ll find both summer flounder (also called fluke) and winter flounder at most fish markets – either type works perfectly for this recipe. Look for fillets that are translucent and have a mild, sweet smell with no fishy odor. If you can’t find flounder, sole makes an excellent substitute since it has a similar delicate texture and mild flavor. Fresh is always best, but if you’re using frozen fillets, make sure they’re completely thawed and patted dry before breading. Just remember that flounder is quite thin, so you’ll want to handle it gently to prevent the fillets from breaking apart.

Options for Substitutions

This recipe is pretty flexible and you can make several swaps while still getting great results:

• Flounder/sole: Any thin white fish fillet will work here – try tilapia, cod, or even catfish. Just make sure the fillets are thin and of similar thickness for even cooking.
• Breadcrumbs: Regular breadcrumbs work fine – just add your own Italian seasoning. You can also use panko for extra crunch, or crushed crackers in a pinch. Gluten-free breadcrumbs are a good option for those avoiding gluten.
• Arugula: Not a fan of arugula’s peppery kick? Baby spinach, watercress, or any mixed salad greens will do the job nicely.
• Capers: If you’re not into capers, try chopped green olives or skip them altogether – the dish will still taste great.
• Parmesan cheese: Romano or Grana Padano make good alternatives. For a dairy-free version, try nutritional yeast for a similar savory flavor.
• Butter and olive oil combo: You can use all olive oil instead of the butter-oil mix, though you’ll miss some richness. Avocado oil is another good option for high-heat cooking.

Watch Out for These Mistakes While Cooking

The biggest challenge when cooking flounder is preventing it from becoming tough and rubbery – this delicate fish needs just 2-3 minutes per side, and overcooking is the most common mistake home cooks make.

Getting the oil temperature right is crucial – if it’s not hot enough (around 350°F), the breading will become greasy and soggy instead of crispy, so wait until the oil shimmers before adding the fish.

To ensure your breading stays put and doesn’t fall off during cooking, make sure to pat the fish completely dry before starting the breading process, and press the breadcrumbs firmly onto each fillet.

A common error is crowding the pan – work in batches if needed, as overcrowding will lower the oil temperature and result in soggy fish, and don’t forget to let the cooked fillets rest on a paper towel-lined plate to keep them crispy.

What to Serve With Flounder Milanese?

This light and crispy fish dish pairs beautifully with simple sides that won’t overpower its delicate flavors. While the recipe already includes arugula, you can round out the meal with roasted baby potatoes tossed with herbs, or a side of angel hair pasta dressed with just olive oil and garlic. For a Mediterranean twist, try serving it with a quick cherry tomato salad or some lemon-dressed orzo. I love adding a few lemon wedges on the plate too – there’s something about extra citrus that makes any fish dish feel more complete!

Storage Instructions

Keep Fresh: For the best texture and taste, try to enjoy your Flounder Milanese right after cooking – it’s when the breading is most crispy! If you have leftovers, place them in an airtight container and keep in the fridge for up to 2 days. Store the lemon dressing separately in a sealed jar in the fridge, where it’ll stay good for up to a week.

Make Ahead: You can prep ahead by breading the fish fillets and keeping them covered with plastic wrap in the fridge for up to 4 hours before cooking. The lemon dressing can be made a day in advance – just give it a good shake before using.

Serve Again: To serve leftover flounder, let it come to room temperature for about 10 minutes, then warm it in a 350°F oven for 8-10 minutes until heated through. The breading won’t be quite as crispy as fresh, but it’ll still be tasty. Add fresh arugula and a drizzle of dressing just before serving.

Ingredients

• 6 fillets of flounder or sole (totaling 1 3/4 pounds)
• 1 cup plain flour
• Coarse salt
• Fresh black pepper
• 2 very large eggs
• 1 1/4 cups seasoned dry breadcrumbs
• Unsalted butter
• High-quality olive oil
• 6 ounces arugula or mixed greens
• 2 tablespoons drained capers
• Fresh grated parmesan cheese
• Juice of lemon
• Finishing salt
• ### lemon dressing:
• 1/4 cup fresh lemon juice
• 1/2 cup high-quality olive oil
• Coarse salt
• Fresh black pepper

Step 1: Preheat the Oven and Prepare the Pan

Begin by preheating your oven to 250°F (120°C).

Place a sheet pan in the oven to warm up.

This will be used later to keep your cooked flounder fillets warm as you prepare the rest of the dish.

Step 2: Prepare the Flounder and Coating Stations

Pat the flounder fillets dry on both sides using paper towels to ensure they are not overly moist.

On a dinner plate, mix 1 cup of all-purpose flour with 2 teaspoons of kosher salt and 1 teaspoon of freshly ground black pepper.

In a low, shallow bowl, whisk together 2 extra-large eggs and 1 tablespoon of water.

On another plate, spread out 1 1/4 cups of seasoned dry bread crumbs.

You’ll be using these setups to coat the fillets.

Step 3: Coat the Flounder Fillets

First, dredge each fillet on both sides in the seasoned flour, making sure to shake off any excess.

Next, dip both sides of the floured fillets into the egg mixture, letting the excess drip off.

Finally, dredge both sides of each fillet in the bread crumbs, ensuring an even coating.

Step 4: Cook the Flounder Fillets

In a large (12-inch) sauté pan, heat 1 tablespoon of unsalted butter and 1 tablespoon of good olive oil over medium to medium-high heat.

Once the butter is melted and the oil is hot, add 2 fillets to the pan.

Cook each side for 2 to 3 minutes, or until they are cooked through and golden brown.

Step 5: Keep Fillets Warm and Repeat

Transfer the cooked fillets in a single layer to the preheated sheet pan in the oven to keep them warm.

Repeat the cooking process with any remaining fillets until all are cooked.

Ensure each batch is kept warm in the oven until ready to serve.
