Ingredients In Baked Cod Fish Sliders

  • SLIDER BUNS: I recommend Brioche or white slider buns because they are light, fluffy, and toast up beautifully. You can also use dinner rolls, or pretzel slider buns. I do not recommend Hawaiian rolls because the sweet bread gives these sliders an odd taste.
  • COD FISH FILLETS: The key to a really good fish sandwich is the fish, of course! Feel free to use fresh or frozen, BUT make sure the cod fillets are as thick as possible. They will be cut in half to fit the size of the slider buns.
  • SEASONING: This recipe uses a simple seasoning blend to not overpower the delicate cod fish flavor.
    • salt
    • pepper
    • paprika
    • garlic powder
  • DILL SAUCE: This is a simple, bright, yogurt based dill sauce. It is best made a day or two in advance so they flavors can develop and meld together.
    • greek yogurt (or sour cream)
    • lemon juice
    • fresh dill
    • clove of garlic
    • dill pickle relish
    • salt
    • pepper
  • LETTUCE: I used butter lettuce but any type will work.
  • RED ONION: This adds crunch to the sandwich. Soak your onion slices in cold water for 30 minutes to take away the strong bite (it’s a life-changing hack).
  • OLIVE OIL: This is used to coat the fish and slider buns before they go in the oven. Be sure to use extra virgin olive oil because it has a high smoke point. This means the oil can withstand high heat without adding an acrid taste to your food.
Ingredients. Slider buns, cod fish, dill sauce, lettuce, red onion, fresh lemon, potato chips, olive oil, paprika, garlic powder, salt, and pepper.

How to Make Fish Sliders

Here is a short summary of the steps, the recipe card below will have complete details.

  1. MIX UP THE DILL SAUCE– In a small bowl whisk together greek yogurt, lemon juice, fresh dill, grated garlic, dill pickle relish, salt and pepper. Refrigerate your sauce so the flavors can develop while you continue.
  2. BAKE THE COD FISH AND SLIDER BUNS- Place the fish and buns and a rack lined baking sheet. Spray or brush liberally with olive oil and season the fish with seasoning blend. Bake for 8 to 10 minutes.
  3. CONSTRUCT THE SLIDERS- Slider bottoms on the bottom, dill sauce, lettuce, red onion, baked cod fish, and slider tops. To help hold them together, use these bamboo skewers.

PRO TIP: To remove the sharp overwhelming bite from your onions, soak them! Just slice or dice the onions, soak them in cold water for 30 minutes, remove from the cold water, and pat dry.

Storing Information

These fish sliders are best stored in the refrigerator, and covered in an airtight container, for up to three days. To reheat them just pop them in the microwave for 30 seconds or until warmed.

What To Serve With Baked Cod Fish Sliders

We love Fish and Chips in my family, so I like to serve these sliders with plain kettle potato chips. Here are a few other fun ideas:


TRY A DIFFERENT SAUCE- Besides the homemade dill sauce you can also top these sliders with Chipotle Southwest Sauce, Sriracha Aioli, or even traditional tartar sauce.

ADD CHEESE- Some people love cheese on their fish sandwiches (I confess I am not one of those people). Sliced American cheese is a classic but you could put whatever you like on them.

TOP WITH COLESLAW- For something even more unique, try adding a fresh coleslaw in place of the lettuce and red onion.

USE OTHER SEASONING BLENDS- Old Bay, Cajun seasoning, lemon pepper, or cumin. Just make sure the seasoning is not too overwhelming, you still want to taste the fish.

SWAP THE COD FISH- This recipe doesn’t need to be with cod. You could swap it out for salmon, white fish, etc. Or you could use the cod but make it beer battered fish instead!

Frequently Asked Questions (FAQ’S)

Are cod fish healthy?

Cod fish is known to be high in protein and low in fat and calories. It is also high in various vitamins and minerals including Omega-3 fatty acids (which our body cannot produce on it’s own). Baked cod fish will always be the healthier to fried cod fish.

What is a substitution for cod fish?

Other white fish like Grouper, Haddock, Pollack, Bass, Halibut, or Tilapia. You can even make these sliders with salmon, tuna, or shrimp.

When is cod fish cooked?

There are 3 ways to tell if your cod fish is fully cooked. One, the thickest part of the fish fillet should be 125 to 145 degrees F with a digital thermometer. Two, press the back of a fork on the thickest part of the fish fillet and it should give way and flake apart. Three, the color of the cod fish will be an opaque white or beige color.
