Italian Eel Recipes: Eel in Tomato and Wine

This Italian-style anguilla in umido is eel gently simmered with onion, garlic, white wine, tomatoes, and parsley until tender and coated in a savory sauce. The exact seasonings vary by region and household; this straightforward version makes a satisfying main course with bread or polenta to catch every spoonful.

Ingredients

2 lb (900 g) eel, cleaned, skinned if desired, and cut into 2-inch (5 cm) pieces
2 tbsp (30 ml) extra-virgin olive oil
1 medium yellow onion, finely chopped, about 1 cup (150 g)
2 garlic cloves (6 g), finely chopped
½ cup (120 ml) dry white wine
1 can crushed tomatoes, 14½ oz (410 g)
½ cup (120 ml) water or unsalted fish stock
1 bay leaf
1 tsp (6 g) fine salt, plus more to taste
¼ tsp (0.5 g) freshly ground black pepper
⅛ tsp (0.3 g) red pepper flakes, optional
¼ cup (15 g) chopped fresh flat-leaf parsley, divided
1 tbsp (15 ml) fresh lemon juice, or to taste

Instructions

Prepare the eel and aromatics. Ask the fishmonger to clean and cut the eel into manageable pieces; eel can be difficult to handle and slippery when raw. Pat the pieces dry with paper towels and check for any remaining viscera or loose bone fragments. If the eel is not already cut, use a sharp knife and a stable board, taking care not to let it slide. Chop the onion, garlic, and parsley, and measure out the remaining ingredients. Season the eel with the salt and black pepper.
Brown the eel. Warm the olive oil in a wide, heavy pot or deep skillet over medium heat. When the oil shimmers, add the eel in a single layer, working in batches if needed so the pieces are not crowded. Brown for about 3 to 4 minutes per side, turning carefully with tongs. The pieces do not need to cook through at this stage. Transfer them to a plate; leave the flavorful oil in the pot.
Soften the onion and garlic. Add the chopped onion to the pot and cook for 4 to 5 minutes, stirring often, until it softens and turns translucent without taking on much color. Stir in the garlic and optional red pepper flakes and cook for about 30 seconds, just until fragrant. If the pot looks dry, lower the heat rather than adding more oil immediately; the onion will release some moisture as it cooks.
Deglaze with wine. Pour in the white wine and scrape the bottom of the pot with a wooden spoon to release any browned bits. Let it bubble for about 2 minutes, until the sharp smell of alcohol has eased and the liquid has reduced slightly. This step gives the sauce a rounded flavor rather than leaving it wine-forward.
Make the tomato sauce. Add the crushed tomatoes, water or fish stock, and bay leaf. Stir, bring the sauce to a gentle simmer, and cook uncovered for 5 minutes. Taste a small spoonful and adjust the salt if needed. Keep the heat at a quiet bubble; a hard boil can make the sauce splatter and can break delicate fish pieces apart later.
Simmer the eel until safely cooked. Return the browned eel and any juices on the plate to the pot. Nestle the pieces into the sauce, cover partially, and simmer gently for 18 to 20 minutes, turning the pieces once with care. Check the thickest piece with a food thermometer: the USDA FSIS safe minimum internal temperature for fish is 145°F (63°C). If it has not reached that temperature, continue simmering and check again after a few minutes. Eel should be tender but still hold its shape; avoid prolonged vigorous cooking.
Finish and serve. Remove the bay leaf. Stir in most of the parsley and the lemon juice, then taste the sauce. Add a little more salt, pepper, or lemon if it needs lift. Scatter the remaining parsley over the top and bring the pot to the table, or transfer the eel and sauce carefully to a warm serving dish.

Tips

Get the fish prepared for you. Cleaned, portioned eel is the most practical choice for a home cook. If it is sold with the skin on, that is fine for this stew; the skin softens as it simmers. Ask the fishmonger to remove the head and innards and cut the eel into even pieces so they cook at a similar rate.
Use a gentle simmer. Eel pieces can be tender and may break if stirred vigorously. Turn them once with tongs or a spoon, and move the pot by its handles to redistribute sauce if needed. A wide pot helps the pieces sit in one layer and cook evenly.
Choose a sensible substitute if eel is unavailable. Monkfish or firm catfish can stand in, using the same weight and checking each piece for 145°F (63°C). Their flavor is milder and their texture is less rich than eel, so the result will be a tomato-and-fish stew rather than a close match. Add the substitute after the sauce has simmered for 5 minutes, since it may cook faster than eel.
Balance the sauce at the end. Tomato acidity and wine vary. Lemon is best added after cooking, a little at a time, so it brightens the sauce without making it sour. If the sauce tastes sharp, simmer it for a few extra minutes or stir in a tablespoon of water; do not mask it with a large amount of sugar.

Serving Suggestions

Serve the eel hot with crusty bread, toasted country-style bread, or grilled bread. Bread is especially useful here because the tomato, wine, and cooking juices are as much a part of the dish as the fish. For a more substantial meal, spoon the eel and sauce over soft polenta or alongside plain boiled potatoes. Polenta is a particularly good partner when you want something mild that absorbs the sauce without competing with it.

A simple green salad dressed with olive oil and vinegar or lemon provides a fresh contrast. Cooked greens, such as sautéed spinach or chard, also work well; keep their seasoning simple so the parsley and garlic in the stew remain distinct. Offer extra lemon wedges and chopped parsley at the table. If serving several people, warn them that eel can contain small bones even when it has been carefully prepared, and provide a plate for any bones they remove.

Variations

Italian eel dishes have regional and household variations, and this tomato-based preparation is one flexible approach rather than a claim to a single definitive recipe. For a more herb-forward sauce, add a small sprig of rosemary or a few thyme leaves with the bay leaf, then remove woody herbs before serving. Use restraint: a strong herb can easily overwhelm the eel.

For a lighter, less tomato-heavy version, replace half the crushed tomatoes with an additional ½ cup (120 ml) of water or fish stock. The sauce will be thinner and less tangy, so simmer it uncovered for a few extra minutes before returning the eel to the pot. For more heat, increase the red pepper flakes slightly, or leave them out entirely for a gentler family-style dish.

If you cannot find eel, monkfish is a useful firm-fleshed alternative, while catfish is usually easier to find and more economical. Neither tastes exactly like eel: monkfish is leaner and mild, while catfish has a softer, sometimes earthier character. Cut either fish into similarly sized chunks, add it only after the tomato sauce has cooked for 5 minutes, and use the thermometer rather than relying on the recipe time alone. A little extra parsley and lemon can help keep the milder substitute lively.

Storage and Reheating

Refrigerate leftover eel within 2 hours of cooking, in a covered shallow container. Cooked fish keeps for 3 to 4 days in the refrigerator. Store the sauce with the eel rather than separating it; the sauce helps protect the pieces from drying out. If the room is very warm, do not leave the pot out while everyone lingers at the table—portion the leftovers into containers promptly and chill them.

Reheat only the amount you plan to eat. Warm the eel and sauce in a covered saucepan over low heat, turning the pieces gently, until the center reaches 165°F (74°C), the USDA FSIS temperature for reheated leftovers. Add a splash of water if the sauce has thickened in the refrigerator. Avoid repeated reheating or a hard boil, which can make the fish break apart. Discard leftovers that have been left at room temperature for more than 2 hours.

Frequently Asked Questions

Do I need to remove the skin from eel?
Not necessarily. Eel is often sold cleaned and may be cooked with the skin on; it softens during simmering and helps the pieces stay together. If you prefer it without skin, ask the fishmonger to remove it, since handling a slippery whole eel at home can be awkward.

How can I tell when eel is cooked?
Use a food thermometer in the thickest part of a piece and make sure it reaches 145°F (63°C), the USDA FSIS safe minimum for fish. The flesh should also look opaque and feel tender. Color and texture are useful clues, but a thermometer is the reliable safety check, especially when pieces vary in thickness.

Can I make this recipe without wine?
Yes. Replace the ½ cup (120 ml) wine with an equal amount of unsalted fish stock or water. The sauce will lose some depth and acidity, so finish with lemon juice to taste. Do not use vinegar as a direct one-for-one substitute; it is much sharper than wine.

Is eel in tomato sauce very bony?
Eel can have small bones, and the number depends on how it has been cleaned and portioned. Ask the fishmonger for well-trimmed sections and inspect each piece as you eat. Take care when serving children or anyone who may have difficulty noticing small bones.

Can I prepare the sauce ahead?
Yes. Cook the tomato sauce through the 5-minute simmer, cool it promptly, and refrigerate it in a covered container for up to 3 days. When ready to serve, bring the sauce to a gentle simmer, add the browned eel, and cook until the thickest piece reaches 145°F (63°C). The finished dish can also be cooked ahead and reheated, though the eel may become more delicate after storage.

What should I serve if I cannot find Italian-style polenta?
Ordinary cornmeal cooked into soft polenta works well; it does not need to be a specialty product. Crusty bread, potatoes, or plain rice are also practical choices. Each gives you a mild base for the sauce while keeping the eel itself as the main feature.
