Fast Answer
This dish lives or dies on not overcooking the cod — pull it from the pan while it still gives slightly to a fork, since it keeps cooking in the hot sauce after you plate it.
A Recipe I've Been Chasing Since the 1980s
I used to eat at a restaurant on New York’s Lower West Side back in the 1980s where they called this dish Sole Portuguese — made, as the name suggests, with sole. I loved it, but sole isn’t cheap, so I started making my own version with cod instead.
It’s not the original, but it’s the one I actually cook, and it works with pretty much any meaty white fish you want to swap in.
A Little About the Swap (and the Sherry)
The restaurant called this dish Sole Portuguese, and that’s exactly what it was — made with sole, not cod. I loved it, but sole is expensive, and I wasn’t going to spend that kind of money re-testing a recipe I was reconstructing from memory.
Cod turned out to be the practical substitute, and it stuck. Any meaty white fish works here — halibut, haddock, even a thicker snapper fillet — the technique doesn’t change, just the price and the cook time.
As for the sherry — I use dry Fino or Amontillado, never the “cooking sherry” sold near the vinegar at the grocery store, since that stuff is salted and doesn’t taste like sherry at all.
Once it hits a hot pan, the alcohol cooks off, leaving a nutty, slightly saline backbone in the sauce that plain wine doesn’t provide.
Start Here
- Context: I built this recipe by memory and trial and error — it's my best reconstruction, not a copy of a written original.
- Fish: use cod fillets of even thickness. An uneven fillet means one end overcooks before the other's done.
- Equipment: one large skillet — the whole dish happens in it, start to finish.
- Before you start: have everything sliced and ready. The sequence moves fast once the sherry hits the pan.
What Most Cooks Get Wrong
- Problem: overcooked cod. It goes from tender to dry and chalky fast, especially once it goes back into the pan for round two.
- Why it happens: searing it too long the first time, or leaving it covered too long at the end because the recipe says "cook for 5 minutes" without checking.
- Fix: sear just until lightly golden, not cooked through — it finishes in the sauce. At the end, check at the 3-minute mark; it's done the moment it flakes easily, not a minute after.
Why This Works
- Sear first, sauce second: browning the cod before it hits liquid builds flavor on the fish itself, not just around it.
- The fond does the work: what browns onto the pan from searing the cod dissolves into the sauce once you deglaze — that's real depth, not seasoning added separately.
- Sherry earns its place: it deglazes the pan and adds a nutty sweetness a plain tomato sauce wouldn't have on its own.
Quick Fixes and Tips
- Cod overcooked: there's no rescuing it once it's dry — this is a timing fix, not a rescue. Pull it earlier next round.
- No dry sherry on hand: dry white wine works as a stand-in, though you lose the specific nutty sherry flavor.
- Sauce too thin: let it reduce a little longer with the fish out of the pan, rather than adding the fish back too early.
- Smoked paprika, not sweet: it's doing real work in the background here — regular paprika won't give the same depth.
What to Serve With This
- Boiled or roasted baby potatoes: soaks up the sauce without competing with the fish.
- Crusty bread: for the sauce you don't want left behind.
- Simple green salad: cuts the richness with something acidic.
- Wine: a dry Fino sherry mirrors what's in the sauce; Vinho Verde or Albariño works if you want something brighter.

Cod Portuguese
Equipment
- large skillet
Ingredients
- 4 cod fillets about 6 ounces each, skinless & boneless
- 2 tablespoons olive oil
- 2 tablespoons butter unsalted
- 1 medium onion thinly sliced
- 2 cloves garlic minced
- 1 red bell pepper thinly sliced
- 1 yellow bell pepper thinly sliced
- ½ cup dry sherry
- 1 cup cherry tomatoes halved
- 1 teaspoon smoked paprika
- salt & freshly ground pepper to taste
- 2 tablespoons fresh parsley chopped, for garnish
- lemon wedges for serving
Instructions
Prepare the Cod
- Pat the fillets dry and season lightly with salt and pepper. Dry fish browns; wet fish steams.
Sear the Cod
- Heat 1 tablespoon olive oil in the skillet over medium-high heat. Sear the cod 2–3 minutes per side, until lightly golden but not cooked through — it finishes later in the sauce.
- Remove and set aside.
Sauté the Aromatics
- Reduce the heat to medium, add the butter and remaining olive oil, and sauté the onion and garlic for 2–3 minutes, until softened.
- Add the bell peppers and cook for 3–4 minutes more minutes.
Deglaze with Sherry
- Pour in the sherry and simmer 2–3 minutes, scraping up the browned bits from searing the cod — that's where a lot of the flavor is.
Add Tomatoes and Paprika
- Stir in the cherry tomatoes and smoked paprika. Simmer 5 minutes, until the tomatoes soften slightly.
- Taste and adjust salt and pepper.
Return the Cod to the Pan
- Nestle the fillets into the sauce, cover, and cook 3–5 minutes. Check at 3 minutes — the cod is done the moment it's opaque and flakes easily, not a minute after.
Finish and Serve
- Scatter parsley over the top and serve hot with lemon wedges.
Notes
Storage and Make-Ahead
- Refrigerator: leftovers keep 1–2 days in an airtight container, though cod is best fresh.
- Reheat: gently, covered, on the stovetop or in a low oven — the microwave tends to make the fish rubbery.
- Not a good freezer candidate: the sauce separates and the fish's texture suffers. Make this one fresh.

Frequently Asked Questions
Why cod instead of the original sole?
The restaurant called this dish Sole Portuguese, and that’s what they actually used. I love sole, but it’s expensive, and cod turned out to be a practical substitute while I was reconstructing the recipe from memory.
Can I use a fish other than cod?
Yes — any meaty white fish works. Halibut and haddock are both good options; just adjust the cook time slightly for thickness. Avoid anything thin and delicate, since it won’t hold up to being cooked twice.
What if I don’t have dry sherry?
Dry white wine is the closest substitute, though you’ll lose some of sherry’s specific nutty sweetness. Skip the cooking sherry sold near the vinegar at the grocery store — it’s salted and doesn’t taste like real sherry.
How do I know when the cod is actually done?
It should flake easily with a fork and look opaque all the way through, not translucent in the center. Check at the earliest suggested time rather than waiting for the full listed time — cod overcooks quickly.
Can I make this ahead?
Not well. Cod’s texture holds up best fresh, so this isn’t a good make-ahead or freezer dish. If you want to prep ahead, slice the vegetables and measure the sherry in advance, and cook the fish itself right before serving.
What’s a good side if I don’t want potatoes or bread?
A simple green salad or steamed green beans provides something acidic or crisp to balance the sauce’s richness.
Is this a traditional Portuguese recipe?
Not exactly — it’s my own reconstruction of a dish I used to eat at a restaurant in New York in the 1980s, built from memory and a lot of trial and error rather than a written original.
