Reheating fish, especially in a microwave, can be a culinary tightrope walk. One wrong move and you’re facing a dry, rubbery, and overwhelmingly fishy result. But fear not! Reheating fish in the microwave can be done successfully with the right techniques and understanding. This comprehensive guide will walk you through the process, ensuring your leftover fish is almost as delicious as the first time.
Understanding the Challenge: Why Fish Can Be Tricky to Reheat
Fish is delicate. Unlike heartier meats, its proteins are sensitive to heat. Overcooking fish, even slightly, leads to moisture loss and a toughened texture. Microwaves, known for their uneven heating patterns, can exacerbate this issue. The microwave heats food by exciting water molecules, and fish is inherently high in moisture content. This makes it prone to rapid and uneven cooking during reheating.
The biggest concerns when reheating fish are:
- Dryness: Moisture evaporates quickly, leaving the fish dry and unappetizing.
- Rubbery Texture: Protein denaturation causes the fish to become tough and rubbery.
- Fishy Odor: Reheating intensifies the fishy aroma, sometimes to an unpleasant level.
- Uneven Heating: Parts of the fish can be piping hot while other areas remain cold.
Essential Steps Before You Even Touch the Microwave
Success starts before you even consider turning on the microwave. Proper preparation and storage are crucial for achieving the best results.
Proper Storage is Key
How you stored your fish initially significantly impacts its ability to be reheated well.
- Cool it Quickly: After cooking, cool the fish as quickly as possible. Don’t leave it at room temperature for more than two hours.
- Airtight Container: Store the fish in an airtight container to prevent it from drying out and absorbing odors from the refrigerator.
- Refrigerate Promptly: Refrigerate the fish within two hours of cooking. Store it in the coldest part of your refrigerator (usually the bottom shelf).
- Eat Sooner Rather Than Later: Aim to reheat and consume the fish within one to two days of initial cooking. The longer it sits, the more its quality deteriorates.
Preparing the Fish for Reheating
Before microwaving, take a few moments to prepare the fish properly.
- Remove from the Refrigerator: Take the fish out of the refrigerator about 15-20 minutes before reheating. This allows it to warm up slightly, promoting more even heating in the microwave.
- Add Moisture: Adding a small amount of moisture will help prevent the fish from drying out. A drizzle of water, lemon juice, or even a light brushing of olive oil can make a big difference.
- Consider Covering: Covering the fish during reheating helps trap moisture and promotes even heating. Use a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape.
Mastering the Microwave: The Right Settings and Techniques
Now, let’s get to the heart of the matter: using the microwave effectively to reheat fish.
Choosing the Right Power Level
Microwaving fish on high power is a recipe for disaster. The goal is to gently warm the fish without overcooking it.
- Low and Slow Wins the Race: Use a low power level, ideally 50% or even lower. This allows the fish to heat more evenly and prevents it from becoming dry or rubbery.
- Patience is a Virtue: Reheating fish in the microwave requires patience. It will take longer at a lower power level, but the results will be worth it.
The Importance of Timing and Rotation
Consistent monitoring and strategic rotation are crucial.
- Start Small: Begin with short intervals of heating, such as 30 seconds to 1 minute.
- Check Frequently: After each interval, check the fish’s internal temperature and overall texture.
- Rotate Strategically: Rotate the fish in the microwave between heating intervals to ensure even heating. If the fish is a large fillet, turn it over as well.
- Use a Thermometer: An instant-read thermometer is your best friend. Aim for an internal temperature of 145°F (63°C).
Specific Fish Types and Their Reheating Nuances
Different types of fish have different textures and fat contents, influencing how they reheat.
- Lean Fish (Cod, Tilapia, Flounder): Lean fish tend to dry out more easily. Be extra diligent about adding moisture and using a low power level.
- Fatty Fish (Salmon, Mackerel, Tuna): Fatty fish are more forgiving due to their higher fat content, which helps retain moisture. However, still be careful not to overcook them.
- Breaded or Fried Fish: Reheating breaded or fried fish in the microwave is generally not recommended, as the breading will become soggy. If you must, try placing a paper towel underneath to absorb some of the moisture. An air fryer is a far better option for these types of fish.
Minimizing the Fishy Odor
One of the biggest complaints about reheating fish is the intensified fishy smell. Here are some tips to minimize it:
- Lemon Power: Adding lemon juice before reheating can help neutralize the odor.
- Ventilation is Key: Ensure your kitchen is well-ventilated. Open a window or turn on the exhaust fan.
- Clean the Microwave: Immediately after reheating, clean the microwave to remove any lingering fishy residue. Use a solution of water and vinegar or a microwave-safe cleaner.
Beyond the Microwave: Exploring Alternative Reheating Methods
While this guide focuses on microwaving, it’s important to acknowledge that other methods might yield even better results.
Oven Reheating: A Gentler Approach
Reheating fish in the oven is a slower but gentler method that can help retain moisture and prevent overcooking.
- Preheat and Wrap: Preheat your oven to a low temperature, around 275°F (135°C). Wrap the fish in aluminum foil with a drizzle of olive oil or lemon juice.
- Monitor Closely: Bake for about 10-15 minutes, or until the fish is heated through. Use a thermometer to ensure it reaches 145°F (63°C).
Steaming: Maintaining Moisture
Steaming is an excellent way to reheat fish while preserving its moisture content.
- Gentle Steam: Place the fish on a steamer basket over simmering water.
- Keep it Covered: Cover the pot and steam for about 5-7 minutes, or until heated through.
Pan-Frying: Reviving Crispy Skin
If your fish has crispy skin, pan-frying can help revive it.
- Medium Heat: Heat a small amount of oil in a skillet over medium heat.
- Skin-Side Down: Place the fish skin-side down in the skillet and cook until the skin is crispy and the fish is heated through.
Reheating Different Types of Fish Dishes
The method you use might slightly alter depending on how the fish was prepared initially.
Reheating Grilled Fish
Grilled fish can dry out quickly. Try wrapping it in foil with a little butter and lemon juice before reheating in the oven or microwave.
Reheating Baked Fish
Baked fish usually reheats well in the oven at a low temperature. Again, wrapping it in foil helps retain moisture.
Reheating Fried Fish
Reheating fried fish in the microwave leads to soggy results. An air fryer or oven is a better option for restoring crispness.
Reheating Fish in Sauce
Fish already in sauce is one of the easier items to reheat. The sauce helps maintain moisture and flavor. Reheat in the microwave on low, stirring occasionally, or gently warm it on the stovetop.
Troubleshooting Common Problems
Even with the best techniques, things can sometimes go wrong. Here’s how to address common issues:
- Dry Fish: If the fish is dry, try adding a small amount of broth or sauce during reheating.
- Rubbery Texture: If the fish becomes rubbery, it’s likely overcooked. Unfortunately, there’s no real fix for this. Prevention is key.
- Uneven Heating: If the fish is heating unevenly, rotate it more frequently during reheating and consider cutting it into smaller pieces.
- Strong Fishy Odor: If the odor is overpowering, try adding more lemon juice or vinegar. Proper ventilation is also crucial.
Serving Suggestions for Reheated Fish
Reheated fish can be just as enjoyable as freshly cooked fish if done right.
Consider pairing your reheated fish with:
- Fresh Vegetables: A side of steamed or roasted vegetables adds freshness and nutrients.
- Salads: A light and refreshing salad complements the richness of the fish.
- Grains: Quinoa, rice, or couscous make excellent side dishes.
- Sauces: A flavorful sauce can elevate the taste of the reheated fish.

Why is reheating fish in the microwave often discouraged?
Reheating fish in the microwave is often discouraged due to its tendency to dry out the fish, leading to a tough and unappetizing texture. The microwave’s heating process can also intensify the fishy odor, making the experience less pleasant. These issues contribute to the perception that microwaving fish is inferior to other reheating methods.
Furthermore, certain types of fish, especially delicate ones, are particularly prone to overcooking in the microwave’s uneven heat distribution. This can result in a rubbery consistency and a loss of the original flavor profile. Therefore, careful attention and specific techniques are crucial to successfully reheating fish in the microwave.
What types of fish reheat best in the microwave?
Firm, white fish like cod, halibut, or mahi-mahi generally reheat better in the microwave than more delicate or oily fish. Their denser texture allows them to withstand the microwaving process with less risk of becoming overly dry or falling apart. Additionally, fish that was initially cooked with some moisture, such as steamed or poached fish, tends to retain more moisture during reheating.
However, regardless of the type of fish, success depends heavily on the reheating technique. Covering the fish with a damp paper towel, using a lower power setting, and monitoring it closely are essential for preserving its texture and flavor. Oily fish like salmon can be microwaved, but the risk of drying out or developing a strong odor is higher, requiring even greater care.
What are the best practices for reheating fish in the microwave?
The key to successfully reheating fish in the microwave is to use a low power setting, typically 50% or less, and to monitor the fish closely. This prevents rapid overheating, which can lead to dryness and uneven cooking. Place the fish in a microwave-safe dish and cover it with a damp paper towel to help retain moisture and prevent splattering.
Reheat in short intervals, usually 30-second bursts, checking the fish after each interval. The goal is to warm the fish through without overcooking it. Once the fish is heated to an internal temperature of 165°F (74°C), it’s ready to eat. Overheating is the biggest pitfall, so err on the side of caution and stop microwaving when the fish is just warm, allowing the residual heat to finish the process.
How can I prevent my fish from drying out when reheating in the microwave?
Preventing dryness is paramount when reheating fish in the microwave. The most effective method is to create a moist environment. This can be achieved by covering the fish with a damp paper towel or placing a few tablespoons of water or broth in the dish with the fish. The moisture helps to steam the fish during reheating, preventing it from drying out.
Another crucial step is to avoid overheating. Use a low power setting (50% or less) and reheat in short intervals, checking for doneness frequently. Consider adding a pat of butter or a drizzle of olive oil before reheating to further enhance moisture and flavor. Overcooked fish is invariably dry, so careful monitoring is essential.
How do I reduce the fishy smell when reheating fish in the microwave?
The fishy smell associated with reheating fish, particularly in the microwave, can be mitigated with a few simple tricks. First, ensure your microwave is clean and free of lingering odors. Wiping it down with a mixture of water and lemon juice or vinegar can help neutralize smells. Adding a slice of lemon or a sprig of fresh herbs like dill or parsley to the dish while reheating can also help to mask the fishy aroma.
Ventilation is also important. Open a window or turn on the exhaust fan to allow any escaping odors to dissipate quickly. Some people also find that placing a small bowl of baking soda in the microwave can absorb odors during and after reheating. Lastly, avoid overcooking the fish, as overcooked fish tends to have a stronger and more unpleasant smell.
What is the ideal internal temperature for reheated fish?
The ideal internal temperature for reheated fish is 165°F (74°C). This temperature ensures that the fish is thoroughly heated and safe to consume, killing any potential bacteria that may have developed during storage. Using a food thermometer is the most accurate way to verify the internal temperature.
Insert the thermometer into the thickest part of the fish to get an accurate reading. Remember that the fish will continue to cook slightly even after it’s removed from the microwave, so it’s best to err on the side of caution and not overcook it. Aim for 165°F (74°C) and allow the residual heat to finish the process, ensuring a safe and flavorful reheated fish dish.
Can I reheat breaded or fried fish in the microwave?
Reheating breaded or fried fish in the microwave is generally not recommended, as the breading tends to become soggy and lose its crispy texture. Microwaves heat food from the inside out, which can trap moisture and lead to a less desirable result. The breading, designed to be crispy, absorbs this moisture and becomes soft.
However, if you must reheat breaded or fried fish in the microwave, try placing it on a microwave-safe rack or paper towel to allow for some air circulation. Reheat in short intervals on a low power setting, and be prepared for a texture that is less than ideal. For best results, consider using an oven or air fryer to restore the crispiness of the breading.
