Selecting the Perfect Flounder
When I’m at the fish market, here’s what I look for:

- Skin should be moist and shiny
- There should be no strong fishy smell – just a clean ocean scent
- The flesh should spring back when gently pressed
Storage Tips
To maintain freshness, I recommend:
- Keep fresh flounder wrapped in paper towels and sealed in a plastic bag
- Store in the coldest part of your refrigerator (32-34°F)
- Use within 1-2 days of purchase
- If freezing, wrap tightly in plastic and aluminum foil
- Frozen flounder keeps for up to 3 months
Essential Preparation Steps
Before cooking, follow these crucial steps:
- Rinse the fish under cold water
- Pat completely dry with paper towels
- Check for any remaining scales

Q&A Section
Q: How do I know when flounder is fully cooked?
The flesh should be opaque and flake easily with a fork. When you insert a knife into the thickest part, it should slide through with no resistance.
Q: Can I cook flounder from frozen?
While possible, I strongly recommend thawing first for better results. Thaw overnight in the refrigerator for best texture.
Q: Why does my flounder sometimes curl up when cooking?
This happens due to the connective tissue contracting. Making a few small cuts in the flesh before cooking can help prevent this.
Q: Is it better to cook flounder with the skin on or off?
For pan-searing, I prefer skin-on as it helps hold the delicate flesh together. For baking or steaming, either way works well.
Q: How long can I keep leftover cooked flounder?
Store in an airtight container in the refrigerator for up to 2 days. Reheat gently to prevent drying out.
Troubleshooting Common Issues
| Problem | Cause | Solution |
|---|---|---|
| Fish breaks apart | Too much handling | Use proper tools, minimize flipping |
| Sticking to pan | Pan not hot enough | Preheat properly, use enough oil |
| Rubbery texture | Overcooked | Use timer, check early |
| Watery result | Fish not dried properly | Pat thoroughly dry before cooking |
