Greek One-Pot Cod Plaki With Potatoes: Easy Traditional Bakaliaros Plaki For Home Cooks

This one-pot take on bakaliaros plaki, Greek cod baked (here: simmered) in a rich tomato-herb sauce with potatoes, lets a home cook get authentic flavor without hauling out multiple pans. It’s built around pantry-friendly ingredients, straightforward technique, and a forgiving simmer that keeps the fish moist. The recipe below uses salted or fresh cod, explains why the layering matters, and gives timing cues so they can serve a classic Greek comfort dish the first time through.

Why This One-Pot Greek Cod Plaki With Potatoes Works

Plaki (πλάκι) is a casserole-style method where fish is cooked in a tomato-based sauce with aromatics. This one-pot variation adapts that idea for a stovetop pot: potatoes become both a bed and a starch-thickener, absorbing tomato flavor while gently steaming the cod above.

There are three practical strengths to this approach. First, heat distribution: a heavy-bottomed pot provides even, gentle heat so delicate white fish like cod won’t overcook. Second, flavor integration: as potatoes simmer they release starch that mildly thickens the sauce, marrying the tomatoes, olives, and herbs. Third, cleanup and control, less oven time and fewer pans mean a lower chance of dried-out fillets.

Technique notes matter. Use a pot with a tight-fitting lid to trap steam, and keep the simmer low so the fish flakes rather than crumbles. If using salted cod (preserved cod), pre-soak to remove excess salt, this step is essential for balance.

Ingredients

Base ingredients below serve about 4 people. Adjust quantities proportionally for larger or smaller groups.

• 1.5 lb (about 680 g) cod fillets, fresh or rehydrated salted cod (see prep notes). If using bone-in pieces, increase simmer time slightly.
• 2 lb (about 900 g) potatoes, peeled and cut into 1/3–1/2″ (8–12 mm) slices or wedges.
• 1 can (14 oz / 400 g) crushed tomatoes or 3–4 fresh tomatoes, peeled and chopped.
• 1 medium onion, thinly sliced.
• 3 garlic cloves, minced.
• 1/3 cup (80 ml) extra-virgin olive oil.
• 1/2 cup (120 ml) dry white wine or fish stock (optional: adds depth).
• 2 tbsp chopped fresh parsley, plus 1 tbsp dill or oregano if desired.
• 1 tsp dried oregano, 1/2 tsp red pepper flakes (optional).
• Salt and black pepper to taste after considering salted cod.
• Optional: 1/3 cup pitted Kalamata olives, halved: 1–2 bay leaves.

Tools: heavy-bottomed pot or Dutch oven (3–5 qt), chef’s knife, cutting board, tongs or spatula, measuring cups, and a slotted spoon for serving.

Safety: Use oven mitts when handling a hot pot lid and wear an apron. For sharp tasks, wear cut-resistant gloves if they’re uncomfortable with knife work.

Substitutions, Sourcing, And Prep Notes

Fish: If cod isn’t available, use haddock, pollock, or halibut (slightly firmer), adjust cooking times for thickness. For frozen fillets, thaw fully in the refrigerator and pat dry.

Salted cod (bakaliaros): If using salted cod, soak in cold water for 24–48 hours, changing water 2–3 times. This removes excess salt and reconstitutes texture. Taste a small flake before seasoning the sauce.

Potatoes: Yukon Gold or red potatoes hold shape well: russets will break down more and make a softer, thicker sauce. Slice uniform thickness for even cooking.

Tomatoes: Canned crushed tomatoes provide consistent acidity and texture: if tomatoes are very acidic, add a pinch of sugar.

Wine vs. stock: White wine adds acidity and brightness. Use low-sodium fish or chicken stock if wine is undesired.

Herbs and heat: Fresh parsley and dill are traditional. Oregano is common in many Greek kitchens and pairs well with tomato and fish. Red pepper flakes add gentle warmth, omit for no-heat versions.

Measurements and coverage: One can of crushed tomatoes plus 1/2 cup liquid usually covers potatoes and forms a saucy braise. Expect about 20–25 square inches of tomato surface in a 3–4 qt pot.

Step-By-Step Cooking In The Pot

This section covers assembly, layering, and simmer control. The method keeps fish tender while ensuring potatoes fully cook.

1. Heat and aromatics: Warm 3 tbsp olive oil over medium in a heavy pot. Add sliced onion and cook 4–6 minutes until translucent: add garlic and cook 30–45 seconds until fragrant.
2. Build the sauce: Stir in crushed tomatoes, 1/2 cup white wine or stock, dried oregano, bay leaf, and red pepper flakes. Bring to a gentle simmer and taste for salt, remember salted cod will add salt later.
3. Layer potatoes: Add a single layer of potato slices, overlapping slightly. Spoon some tomato over them so they’re partially submerged. Turn heat to low, cover, and simmer 10–12 minutes to soften the potatoes without disintegrating them.
4. Add olives/herbs: Scatter olives and half the parsley across the potatoes. This introduces brine and freshness before the fish goes in.
5. Place the cod: Gently nestle cod fillets on top of the potato layer, skin-side down if present. Spoon sauce over the fillets to keep them moist: do not fully submerge thicker pieces, steam will finish the cook.
6. Final simmer: Cover and simmer on the lowest heat that sustains gentle bubbling. Time based on thickness: 8–12 minutes for 3/4″–1″ (18–25 mm) fillets, up to 15 minutes for thicker cuts. Avoid stirring: the goal is even, gentle heat.

Preparing Potatoes And Fish

Potatoes should be uniform so the whole dish finishes simultaneously. For 1/3–1/2″ slices use a mandoline for speed or a steady chef’s knife for control.

If using salted cod: after soaking and draining, pat dry and check flakiness. Salted cod can be firmer: allow an extra 2–3 minutes of covered simmer if pieces are thick.

Fresh cod: Pat fillets dry to improve browning of any exposed flesh and reduce excess liquid in the pot. If fillets have skin, leave it on, the skin holds fillets together during handling and often crisps slightly at the edges.

Seasoning: Lightly season the fish with black pepper and minimal additional salt until after simmering, re-check after the dish finishes. This avoids over-salting, especially with olives or preserved fish.

Simmering, Timing, And Finishing Touches

Timing: Total active stovetop time is roughly 30–40 minutes: 6–8 minutes sautéing, 10–12 minutes pre-simmer for potatoes, then 8–15 minutes with fish depending on thickness.

Doneness cues: Fish is done when it flakes easily with a fork and looks opaque through the thickest part. Potatoes are done when tender to a paring-knife, no raw center.

Finishing: Remove from heat and let rest, covered, 3–5 minutes. This evens residual heat and helps flavors meld. Finish with chopped fresh parsley and a drizzle of extra-virgin olive oil for brightness.

Serving: Serve directly from the pot family-style or transfer to a shallow serving dish. Offer crusty bread (for mopping sauce) and lemon wedges for acidity.

Storage and reheating: Refrigerate leftovers within 2 hours in an airtight container for up to 3 days. Reheat gently on the stovetop over low heat, add a splash of water or stock to loosen sauce. Avoid microwaving for long intervals: it can overcook delicate fish.

Safety and code notes: This is a non-structural kitchen activity, no permits needed. Follow standard kitchen safety: use potholders, cut away from the body, and keep children away from hot cooktops.

Conclusion: Serving Tips, Storage, And Final Notes

Bakaliaros plaki in one pot is forgiving and flavorful, ideal for weeknights or a low-fuss dinner with guests. Serve with a simple salad and lemon: a dry white wine pairs well.

Leftovers make a hearty lunch: adjust seasoning after reheating. If they prefer a crisper finish, broil briefly in an ovenproof dish for 1–2 minutes to refresh texture, watching closely to avoid drying the fish.

Final note: Pay attention to potato thickness and the salt level of the cod. Those two variables control success more than any other detail. With modest prep and a low simmer, they’ll achieve a classic Greek dish that’s both comforting and bright.
