Smoky Skillet Tilapia over Eggplant, Peppers, and Lentils
Diced eggplant and red peppers cooked down with smoked paprika and garlic, stirred through with lentils, and tilapia fillets laid on top to steam under a lid.
Why You'll Love This Recipe
This started as a weeknight version of pisto, the soft pepper and eggplant stew that shows up all over Spain with an egg cracked into it. I wanted the same thing under a piece of fish, and it turns out tilapia is the right choice, because it is thin enough to cook through in the five or six minutes the vegetables need to finish. Everything happens in one skillet, the fish never has to be turned, and the only part that takes real time is the eggplant, which cannot be rushed and should not be. It is also a forgiving dish, since the vegetables are happy to sit in the warm pan while you find everyone a fork.
Eggplant needs more oil and more patience than most vegetables. Cut it into cubes rather than slices, give it a hot pan and enough room, and leave it alone until the cut faces are properly brown before you start stirring. What happens then is the good part: the flesh goes from squeaky and spongy to silky, and it stops tasting bitter and starts tasting faintly sweet. The peppers go in halfway through so they soften without turning to mush, and the smoked paprika goes in last, off the strongest heat, because it scorches easily. Taste a cube before the fish goes on, and if it still squeaks against your teeth, give it another two minutes.
By the time the lid comes off, the fish has steamed in the smell of paprika and garlic and the lentils have soaked up the pan juices, so nothing on the plate tastes like it was cooked separately. It is a good dish for the end of a long day because it needs one pan, one lid, and no timing you have to think hard about. I finish it with vinegar and parsley for a sharp edge, and lemon wedges on the side for anyone who wants more. I like it best eaten out of shallow bowls, with the pan back on the stove in case anyone wants more.
Ingredients
- 1 1/3 lb tilapia fillets (4 fillets), patted dry
- 2 tbsp olive oil
- 1/2 medium onion, diced
- 1 medium eggplant (about 1 lb), cut into 3/4-inch cubes
- 2 red bell peppers, seeded and cut into short strips
- 4 garlic cloves, chopped
- 2 tsp smoked paprika
- 1/3 tsp fine sea salt
- 1/2 tsp freshly ground black pepper
- 1 1/4 cups cooked brown lentils, drained and rinsed
- 1 1/4 tbsp cider vinegar, or sherry vinegar if you keep it
- 1 tbsp lemon juice, plus wedges to serve
- 1/2 cup flat-leaf parsley leaves, chopped
Instructions
- Get the vegetables cut first: Cut the eggplant into 3/4-inch cubes, the peppers into short strips, and dice the onion. Chop the garlic and the parsley and set the lentils in a sieve to drain and rinse. Once the eggplant is in the pan it wants your attention, so do all of this before the burner goes on.
- Brown the eggplant: Heat the olive oil in a 12-inch skillet over medium-high until it shimmers, then add the eggplant in an even layer and leave it undisturbed for three minutes so the cut faces brown. Toss and repeat twice, six to eight minutes in all, until the cubes are dark in places and starting to slump. Add the onion and cook two minutes more.
- Add the peppers, garlic, and paprika: Stir in the pepper strips and cook for four minutes, until they go glossy and lose their crunch. Turn the heat to medium, add the garlic, the smoked paprika, the salt, and the pepper, and stir for sixty seconds, just until the pan smells smoky. Paprika burns quickly at high heat, so do not let it sit still.
- Fold in the lentils and lay the fish on top: Stir the lentils through the vegetables and spread everything level. Season the tilapia and lay the fillets on top of the vegetables, tucking any thin tail ends underneath so they cook evenly. Cover the pan, turn the heat to medium-low, and cook for five to seven minutes.
- Check the fish and finish: The tilapia is ready when it is opaque all the way through, flakes at a gentle press, and reads 145°F at its thickest point. Take the pan off the heat, add the vinegar, the lemon juice, and the parsley, and spoon a little of the vegetables over each fillet. Serve straight from the skillet with lemon wedges.
Variations
- Egg on top: Make wells in the vegetables and crack in four eggs in place of the fish, then cover and cook until the whites set, which is how pisto is eaten at home in Spain.
- Green olives: Add a small handful of chopped green olives with the lentils for a briny bite against the sweet peppers.
- Chickpeas: Use a rinsed can of chickpeas in place of the lentils for a firmer, rounder bite underneath the fish.
- Fresh tomato: Add a cup of halved cherry tomatoes with the peppers so they collapse and give the pan more sauce.
- Hot and smoky: Add a pinch of cayenne with the smoked paprika, or use the hot pimenton if you can find it.
Storage & Leftovers
The vegetables and lentils keep four days in a sealed container and taste better on day two, once the paprika and vinegar have settled into the eggplant. Store the fish on top of them rather than in its own container, so it stays moist and picks up more of the smoke overnight.
Reheat covered in a skillet over medium-low with a splash of water for four or five minutes, or in the microwave at half power. Tilapia is thin and reheats fast, so stop while the center is barely warm. Cold, broken into flakes over the vegetables, it also makes a good lunch with no reheating at all.
The vegetable and lentil base freezes well for up to three months and thaws into something almost like a thick sauce. Cooked tilapia does not freeze happily and comes back watery, so freeze the base on its own and cook fresh fillets on top of it when you reheat.
Notes & Tips
- Cut the eggplant into cubes, not slices: Cubes have more cut surface, so more of the eggplant browns and the whole pan tastes toasted rather than steamed.
- Leave the eggplant alone at the start: Three full minutes without stirring is what gives you dark faces on the cubes. Constant tossing gives you pale, spongy eggplant no matter how long it cooks.
- Turn the heat down before the paprika: Smoked paprika scorches in seconds on high heat and turns acrid. Medium heat and sixty seconds of stirring is all it needs to bloom in the oil.
- Tuck the thin ends under: Tilapia fillets taper, and the thin tail overcooks while the middle is still translucent. Folding the last inch underneath evens the thickness out.
- Keep the lid on: The fish cooks in trapped steam here, not in contact with the pan. Lifting the lid to peek adds a minute or two each time, so check once at five minutes and not before.
- Add the vinegar off the heat: Splashed into a hot pan it evaporates and takes its sharpness with it. Off the burner it stays bright and cuts the sweetness of the peppers.
Nutrition & Mindful Eating
- Tilapia, lentils, and a whole pan of vegetables share the work in this skillet. The fish brings the protein, the lentils bring fiber and a firm bite, and the eggplant and peppers cook down into the soft, savory base that carries everything else.
- Tilapia is a thin, mild, quick-cooking fillet that flakes cleanly when it is done, and it carries a good amount of protein along with selenium and B12 in a piece that takes only minutes under a lid.
- Eggplant turns silky once it has browned properly, and the soft fiber in it is what gives this skillet its body, along with the anthocyanins in the dark skin that are worth leaving on.
- Red peppers cooked until they slump go sweeter than they start out, and they hold on to a lot of their vitamin C, which is one reason a pan like this tastes bright even after everything in it has gone soft.
- Smoked paprika, garlic, and a splash of vinegar are what make this taste of somewhere. The paprika brings the wood smoke, the garlic goes sweet in the oil, and the acid at the end lifts the eggplant so the last bite still tastes lively.
- As you eat, notice how the eggplant has gone from firm to almost creamy and how the smoke arrives a beat after the lemon, and let yourself finish the plate slowly enough to know when you have had enough.
Frequently Asked Questions
Do I have to salt the eggplant first?
No. Salting and draining made sense with the older, seedier varieties that were genuinely bitter, and the eggplant in most stores now is not. A hot pan and enough olive oil do more for the flavor than half an hour of sitting under salt ever did.
My eggplant soaked up all the oil and the pan went dry. Now what?
That is normal and it passes. Eggplant drinks oil in the first two minutes and then gives some of it back as the cells collapse. Resist adding more, keep the heat up, and it will release oil and start browning within about four minutes.
Can I use cod or halibut instead?
Yes, though thicker fillets need longer under the lid, closer to nine or ten minutes for a piece of cod an inch and a half thick. Check with a thermometer rather than the clock, and add a splash of water to the pan if the vegetables look dry before the fish is done.
Can I use dried lentils?
You can, but not inside the thirty minutes. Brown or green lentils simmer for about twenty-five minutes on their own, so cook them ahead if you want to go that route. Canned or pouch lentils, rinsed well, go straight into the pan and behave exactly the same.
