Skillet Trout over Corn and Lima Bean Succotash
Trout fillets seared skin side down until the skin crackles, set over a fast succotash of corn, lima beans, zucchini, and blistered cherry tomatoes finished with torn basil and lemon.
Why You'll Love This Recipe
Succotash gets treated as a side dish and I think it is better than that. Corn, beans, and something green in a hot pan is a whole supper if you put a piece of fish on it, and trout is the fish I want there. It is soft and slightly sweet, it cooks in five minutes, and the skin crisps into something worth eating on its own. This is high summer cooking, made when the corn is cheap and the tomatoes are falling off the vine, though frozen corn does an honest job in February.
The trick with succotash is heat and restraint. Corn goes into a dry, hot skillet and is left alone until it browns and starts to jump, which takes maybe two minutes and gives you a toasted flavor no amount of simmering will produce. Then the zucchini and pepper go in fast, the tomatoes on top of them until the skins split and their juice glazes everything, and the beans last just to warm through. Overcook any of it and you get a wet, sweet mush. Pulled at the right moment it stays crisp, sweet, and distinctly separate.
I make this on nights when I want something that eats like a summer plate but still has real substance to it. The whole thing lives in one skillet, the fish is on and off in five minutes, and there is nothing to carve or plate carefully. Lemon and basil at the end keep the sweetness of the corn from taking over. If you have people over, double the succotash and lay the fillets across the top of the pan, which looks far better than it has any right to.
Ingredients
- 4 trout fillets (about 1 1/4 lb total), skin on and patted dry
- 2 cups corn kernels, cut from 3 ears or thawed from frozen
- 1 1/4 cups lima beans, drained and rinsed well
- 2 small zucchini, cut into 1/2-inch dice
- 1 1/2 cups cherry tomatoes, left whole
- 1 red bell pepper, diced small
- 5 scallions, sliced, white and green parts kept apart
- 4 cloves garlic, minced
- 3/4 cup fresh basil leaves, torn
- 2 tbsp olive oil, divided
- 4 tsp lemon juice, plus wedges to serve
- 1 tsp smoked paprika
- 1 tsp coarsely ground black pepper
- 3/8 tsp fine sea salt, divided
Instructions
- Toast the corn: Heat a large cast iron skillet over medium-high until it is genuinely hot. Add the corn dry, spread it flat, and leave it undisturbed for two minutes. It should start to pop and take on brown spots. Toss once, give it another minute, then tip it into a bowl.
- Build the succotash: Add one tablespoon of the oil, then the zucchini, bell pepper, scallion whites, and a quarter teaspoon of the salt. Cook three minutes over medium-high without stirring much, so the zucchini colors on one side. Stir in the garlic and smoked paprika for thirty seconds, then add the cherry tomatoes and press a few with the back of the spoon.
- Bring it together and set it aside: Once the tomato skins have split and released their juice, about two minutes, return the corn and add the rinsed lima beans. Toss for one minute just to heat through, add half the lemon juice and the black pepper, and scrape the whole lot onto a platter. Wipe the skillet out.
- Sear the trout: Set the skillet back over medium-high with the second tablespoon of oil. Season the trout with the remaining salt and lay it skin side down, pressing each fillet flat with a spatula for the first ten seconds so the skin stays in contact. Cook four minutes without moving it, until the skin is bronze and crisp and the flesh has turned pale most of the way up.
- Turn once and finish: Flip the fillets and give them sixty to ninety seconds on the flesh side, no more. Trout is thin and goes from perfect to dry quickly. Lay them over the succotash skin side up, pour on the rest of the lemon juice, tear the basil over the top, and add the scallion greens.
Variations
- Okra succotash: Add a cup of sliced okra with the zucchini for a version that leans further south and thickens the pan juices.
- Charred scallion and lime: Swap lemon for lime and char the scallions whole in the dry pan before slicing them, which gives the whole dish a smokier edge.
- Green bean and dill: Use cut green beans in place of the zucchini and dill in place of the basil for a cooler, more northern version.
- Corn and tomato only: Leave out the beans and double the tomatoes for a looser, juicier pan that eats almost like a warm salad under the fish.
Storage & Leftovers
The succotash keeps four days in a sealed container and is very good cold, straight from the refrigerator with a little more lemon. The corn stays sweet and the beans firm up slightly, which I do not mind at all. Keep the basil off any portion you plan to save and tear fresh leaves over when you eat it.
Reheat the succotash in a dry skillet over medium-high for three minutes, spread flat and left alone at first so some of the corn browns again. Low and slow reheating steams it and the vegetables go limp.
Cooked trout keeps two days but the skin will not crisp again once it has been refrigerated. Flake the fillets off the skin and fold them into the cold succotash for lunch. I do not freeze either part, since trout goes cottony and the zucchini collapses on thawing.
Notes & Tips
- Dry skillet for the corn: Oil lowers the surface temperature and the kernels steam rather than toast. Corn has enough sugar and moisture of its own to brown beautifully in a bare hot pan.
- Press the fillets for ten seconds: Trout skin curls the moment it meets heat, which lifts the middle off the pan and leaves you with a stripe of crisp and a stripe of pale. A few seconds under a spatula fixes it.
- Rinse the lima beans properly: Run them under cold water until the water runs clear rather than cloudy. The packing liquid is thick and it dulls the whole pan when it hits the corn.
- Basil goes on last, off the heat: It blackens and turns to string within seconds of touching a hot skillet. Torn over the platter at the table it stays green and perfumed.
Nutrition & Mindful Eating
- Trout, corn, and lima beans make this a full plate rather than a side dish. The fish carries the protein and the fat, the beans and corn bring the fiber and the starch that make it filling, and the zucchini and tomatoes keep the whole pan juicy.
- Trout is an oily freshwater fish, which is where its softness and its rich flavor come from, and it carries omega-3 fats along with vitamin D and B12. The skin holds a good share of that fat, so crisping it rather than peeling it off is worth doing.
- Lima beans are starchy and mealy in the best sense, going buttery at the center when they are warmed through. They bring fiber and potassium, and they are what turns a pan of vegetables into something that eats like dinner.
- Corn browned in a dry pan tastes almost nutty, and the sugars that caramelize are the same ones that make it sweet raw. Yellow kernels carry lutein and zeaxanthin, the pigments that also give the succotash its color.
- Basil torn in at the end and lemon squeezed over are doing the work that salt usually does. Acid and a strong fresh herb sharpen the edges of sweet corn, which is why the last forkful still tastes lively rather than sugary.
- As you eat, listen for the crackle when your fork goes through the trout skin and taste how the burst tomatoes have sweetened the corn, and take the meal sitting down where you can notice both.
Frequently Asked Questions
Frozen corn or fresh?
Fresh cut from the cob is sweeter and browns better, but frozen works well if you thaw it and pat it dry first. Wet corn steams rather than toasting and you lose the browned flavor that makes this dish. Do not use canned corn here, it is too soft to hold up.
My trout skin stuck to the pan.
Almost always a pan that was not hot enough, or fish that was not dry. Blot the skin thoroughly, heat the skillet until a drop of water dances, and press the fillet flat for the first few seconds. Then leave it alone, because it releases itself once the skin has crisped.
Can I use frozen lima beans?
Yes, and they are often better. Thaw them and add them at the same point. Frozen limas hold a firmer bite than canned, which have already been cooked twice by the time they reach you.
What else can I put on top?
Salmon, arctic char, or thick tilapia fillets all suit this. Shrimp is good too, tossed in for the last ninety seconds with the beans. The succotash is the constant and the protein on top is negotiable.
