This fish hash recipe was one of those accidentally-discovered dishes when one of the ingredients doesn’t turn out quite right, but with a plan B, the dish turns into something quite amazing. I love accidentally discovering great recipes that turn into signature dishes and sharing them with you. What I love about this fish hash recipe is that it’s quick, easy, delicious, satisfying, and packed with flavor. It is also sugar-free, dairy-free, lectin-free, low-carb, Keto, and Paleo!
What’s very convenient about a flaky white fish, such as wild-caught cod, is you can buy it frozen, then bake it without thawing. You may, of course, thaw your fish first or buy fresh fillets. This recipe works well in all of those scenarios. For us busy foodies, we often stock up on frozen cod fillets for easy, longer-term storage, then pop them in the oven last minute to make a quick dinner.
In the past, we would just sprinkle the fish with salt and pepper, top it with butter or drizzle with olive oil once it was cooked, squeeze lemon juice over it, and serve with a salad or veggies. Simple enough. Then Joel started complaining.
He likes variety more than I do, so his complaint was that eating fish this way got “too boring.” Then one evening, I felt like having fish and decided to bake the frozen cod fillets. I had Joel’s complaint in the back of my mind as I was preparing the dinner. Then a funny (and serendipitous) thing happened — the fish got too flaky. It was literally falling apart on the baking sheet. I may have forgotten to grease the baking sheet. Oops.
Hmm, what do I do now? Plan B! We were on a fried-onions-in-butter kick, so I had the idea to sauté some onions, fry a couple slices of bacon, and mix the fish in to make it into a fish hash! I love hash, so why not with fish? A simple Romaine lettuce salad on the side. Boom! Easy dinner. Plus, Joel gets to eat his fish in a new way.
The smokiness and crunchiness of bacon, the sweetness of cooked onions, the delicateness of the fish…this is probably my favorite way to eat cod or tilapia. Top the fish hash leftovers with an egg the next morning, and it’s breakfast! We now make this fish hash recipe quite often. Enjoy!
12 oz. wild-caught cod, or any flaky white fish, frozen, thawed, or fresh
1 large yellow onion, chopped
2-3 slices bacon (I like Niman Ranch No-Sugar Applewood Smoked Bacon)
1/2 teaspoon garlic power
1/2 teaspoon freshly-ground black pepper
Salt to taste (I use Himalayan pink salt for its mineral content)
Flat-leaf Italian parsley, minced (optional)
- Grease a rimmed baking sheet with avocado oil or grass-fed butter. Season the fish with salt on both sides and place on the baking sheet.
- If using fresh fish fillets, pre-heat the oven to 400° F. Depending on the thickness of the fillets, bake for 9-12 minutes, or until the fish flakes easily with a fork, and the center is no longer translucent.
- If using frozen or thawed fish fillets, bake according to the instructions on the package and until the fish flakes easily, and the center is no longer translucent.
- While the fish is baking, fry the bacon slices in a large sauté or cast iron pan over medium heat until crispy or to desired doneness. Remove the bacon and allow to cool.
- Cook the chopped onion in the bacon fat until golden-brown, stirring occasionally, about 7-10 minutes, adding more cooking fat, if needed. Sprinkle with salt, pepper, and garlic powder and mix well. Remove from heat if done before the fish.
- Cut the cooled slices of bacon into small pieces.
- Once the fish is baked, break it into bite-sized pieces with a fork and add to the onion in the pan. Add the chopped bacon, mix well, and allow everything to heat through.
- Adjust the seasonings as desired. Sprinkle with minced parsley, if desired, and serve warm.
When you use the fish hash leftovers for breakfast, it’s very similar in texture to a typical hash loaded with potatoes, but without all of the carbs!
What helps to make this fish hash recipe even quicker is cooking things in parallel — frying the bacon while the oven is heating, cooking the onions while the fish is baking — you get the point. I also like to use a broiler pan instead of a rimmed baking sheet when baking frozen fish to allow the juices to drip into the bottom tray.
Feel free to omit the bacon, but it gives this dish a very nice, smoky flavor and crunchy consistency.
