Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Cod fillets (fresh or thawed)
Focaccia bread, sliced into sandwich portions
Olive oil
Garlic, minced
Onion, finely chopped
Crushed tomatoes or tomato passata
Tomato paste
Fresh basil or parsley
Dried oregano
Red pepper flakes (optional)
Salt and pepper to taste
Lemon juice (optional)
Arugula or baby spinach (optional, for garnish)

Directions

Heat olive oil in a skillet over medium heat. Add the onion and sauté until softened.
Add garlic and cook for 30 seconds, then stir in tomato paste. Cook for 1–2 minutes to enhance the flavor.
Add crushed tomatoes, oregano, red pepper flakes, salt, and pepper. Simmer the sauce for 10–15 minutes, stirring occasionally. Add chopped fresh basil at the end.
While the sauce simmers, pat cod fillets dry and season with salt and pepper.
Heat olive oil in another skillet over medium-high heat. Sear the cod for 3–4 minutes per side, or until the fish flakes easily and is golden on the outside. Add a splash of lemon juice if desired.
Lightly toast the focaccia bread slices.
To assemble, spread a generous layer of tomato sauce on the bottom half of each focaccia slice. Top with cod, more sauce if desired, and a handful of arugula or spinach. Cover with the top slice of bread.
Serve warm with extra sauce on the side, if desired.

Variations

Use ciabatta or sourdough if focaccia is unavailable.
Add mozzarella, provolone, or fresh burrata for a cheesy version.
Substitute cod with haddock, tilapia, or halibut.
Add grilled vegetables like zucchini or roasted peppers for more texture.
Serve open-faced for a lighter option.

Storage/Reheating

For best results, store each component separately. Cooked cod and sauce can be refrigerated in airtight containers for up to 3 days. Reheat the sauce and fish gently on the stovetop or in the microwave. Assemble the sandwiches fresh to maintain the texture of the bread. Fully assembled sandwiches are best enjoyed the same day to prevent sogginess.

FAQs

Can I use frozen cod?

Yes, just make sure to thaw and pat it dry completely before cooking to avoid excess moisture.

What’s the best bread for this sandwich?

Focaccia is ideal for its texture and flavor, but ciabatta or a crusty roll also works well.

Is the sauce spicy?

Only if you add red pepper flakes. You can leave them out for a milder version.

Can I bake the cod instead of pan-searing?

Yes, bake at 400°F (200°C) for 12–15 minutes or until the fish flakes easily.

Can I make the tomato sauce ahead of time?

Absolutely. It stores well in the fridge for up to 4 days and gets even better with time.

What greens go well in this sandwich?

Arugula adds peppery flavor, but baby spinach, basil leaves, or even shredded lettuce work too.

Can I make this sandwich dairy-free?

Yes, the recipe as written is dairy-free. Just avoid adding cheese or creamy sauces.

Can I grill the sandwich like a panini?

Yes, grill the assembled sandwich in a panini press or skillet with a weight on top for a crispy finish.

Can I use other fish?

Definitely. Haddock, halibut, or sea bass are all great alternatives to cod.

What side dishes pair well with this sandwich?

A simple green salad, roasted potatoes, or marinated olives are great side options.
