Broiled Flounder is a delicious recipe that uses a lean, mild white fish that cooks very quickly. Only a few simple ingredients are needed to make this easy fish dinner. For an extra burst of flavor, make the spicy tartar sauce for dipping.
If you'd like to try some of my other flounder recipes, I think you will love my Blackened Flounder, served with a Cajun sauce. Or try Flounder Francaise, which sounds fancy but is easy to make and has a tangy butter sauce. Pan Fried Flounder has the best garlic sauce that we love.
Why this recipe is just so good...
- Easy weeknight dinner: Not in the mood to fry or grill your fish, broiling the fillets is a perfect choice for quick cooking dinner. The flounder will have a lightly crisp top with a tender fillet. Use just a bit of olive oil and some spices and in less than 10 minutes, the fish is done.
- Delicious tartar sauce: So much tastier than store bought, this homemade tartar sauce has a bit of a kick to it from the horseradish and chili sauce.
- Adaptable: We are using some garlic powder, paprika, salt, pepper and all purpose seasoning. (Old Bay is delicious on fish). You can easily make it a bit spicier with some red pepper chili flakes or use your favorite seasoning for flounder. And if you don't like spicier tartar sauce, just leave out the horseradish.
- Some other fantastic sauces that go well with seafood are: Red pepper sauce, Lemon wasabi sauce or Lemon herb sauce.

Ingredient Notes
- Frozen flounder fillet is a great alternative to fresh because it is less expensive, convenient and easily available. Frozen fish is frozen shortly after it's caught which means it's frozen at the peak of freshness. When choosing frozen fish, make sure there aren't ice crystals in the bag. And check that the fillets are vacuum sealed to avoid freezer burn.
- In addition, according to The Better Fish, there is no difference in nutrition or taste between fresh or frozen.
- To defrost frozen fish: leave packaged fish in the refrigerator overnight to defrost. Or place sealed fillets in a bowl of cold water for about 30 minutes. Replace the cold water after 15 minutes.
Ingredients for tartar sauce:
mayonnaise, lemon juice, pickle relish, dijon mustard, chili sauce, Old Bay seasoning, black pepper, dill or tarragon-optional.
How to make broiled flounder
Step 1: Pat dry fish fillets with paper towel. Combine seasonings.
Step 2: Rub a bit of oil onto fish. Pat seasonings onto both sides of flounder.
Step 4: Preheat oven to broil. Use non-stick baking spray or brush a bit of oil onto the broiler to help avoid fish sticking. Place seasoned fillets onto broiler.
Step 5: Broil flounder for 4 minutes. Test with meat thermometer or digital heat gun. If it registers 145°F, it is done. If not, broil another 1-2 minutes. The fish will also flake apart easily when it's done.
How to make spicy tartar sauce
- To make the spicy tartar sauce, combine the relish, mayo, lemon juice, chili sauce, horseradish, mustard and seasonings. If you would like it more or less spicy, adjust the chili sauce and/or horseradish to your liking. Refrigerate until ready to use. It will taste even better after it chills.
Recipe Tips
- Use fresh fish or quick-frozen and individually sealed fish.
- We are using approximately ½ inch thick fish. If you are using thinner fillets or thicker fillets, they will cook more quickly or longer than what is stated in the recipe. Always use your meat thermometer to check if the fish is done.
- Always pat dry excess moisture from the fish. This will allow your fish to brown and become lightly crispy.
- Make sure to preheat the broiler. This allows for quick and even browning of the fish fillets. Keep an eye on it since broiling food cook quickly.
- You can make the tartar sauce earlier in the day or the day ahead. Store in the refrigerator. Bring out to room temperature before serving.
Frequently Asked Questions
How to choose the best fresh flounder filets?
- If you choose fresh flounder, according to FDAC, you should look for:
- A translucent look.
- Flesh that is firm and not separating.
- A mild odor, similar to the ocean.
- No discoloration.
Should I flip fish fillets when I broil them?
No, it is not necessary to flip the fish fillets when broiling. If the flounder is very thin, they will cook quickly. However, if the fillets are thicker than ½ inch, you should flip them to ensure even cooking. Just make sure the temperature reaches 145°F and the fish flakes easily.
What should I serve with broiled flounder?
Since this fish recipe is fresh and light, I recommend serving with some rice or cauliflower rice or quinoa. To flavor the rice or quinoa, I lightly saute it in a bit of olive oil and add just a shake of salt, pepper, garlic and onion powder. You can make it spicier by adding some paprika, Cajun or Italian seasonings.
Some our favorite vegetable side dishes that would go well are Marinated Broccoli, Pan Seared Asparagus or Blackened Green Beans.
