Chef's pro tip
Here are some tips and tricks to make sure your fish and chips turn out perfectly every time.
That's it! With these tips, you'll have a delicious and healthy version of fish and chips in no time. Enjoy!




Storage
This keto fish and chips recipe is best enjoyed straight out of the oven. If you store it in the freezer, it's gonna lose its amazing taste, smell, and texture. But, hey, we get it, sometimes you wanna save some for later. So, if you've got leftovers, you can store the fish and chips separately in containers for up to 24 hours.
Now, when it's time to reheat them, you can pop 'em in the oven or air-fryer to bring back that crispy texture. But let's be real, it might not be as crispy as when it was freshly made. That's just the nature of leftovers, right?
So, our advice? Invite some friends over and enjoy this dish together while it's still piping hot. That way, you won't even have to worry about leftovers!

How to make it healthier
Alrighty, let's talk about cooking methods for this killer recipe! For a healthier option, you bake the fish in the oven at 200°C/390°F for 16-18 minutes or in the airfryer at 200°C/390°F for around 13-15 minutes. This'll give you a nice, crispy result that won't weigh you down.
But, if you're in it for the taste, I gotta say - deep frying is where it's at. That'll get you the classic fish and chips flavor you know and love. So, it's up to you - do you want to keep it light or go for the full-on fried experience? Either way, you'll end up with a delicious meal that's sure to satisfy.
