Save on Pinterest There was a Thursday evening when I had four unexpected dinner guests and a fridge that looked embarrassingly bare. I found cod fillets I'd frozen the week before, a few peppers starting to wrinkle, and a can of tomatoes shoved in the back of the pantry. What came together in that one pot became the dish I now make when I want to feel capable and calm. The kitchen smelled like a spice market, and everyone scraped their bowls clean.
I served this to a friend who swore she didn't like fish, and she went silent halfway through her first bite. She looked up and said it tasted like summer somewhere warm. That moment taught me that the right combination of peppers, tomatoes, and smoky spices can win over even the most reluctant eater. Now I make it whenever someone needs convincing that seafood can be comforting, not just fancy.
Ingredients
- Cod fillets: I always choose skinless and boneless fillets because they cook evenly and no one has to deal with bones at the table, which keeps the meal relaxed and easy.
- Onion: Chop it finely so it melts into the sauce and creates a sweet, savory base that supports all the other flavors without making anyone cry too much.
- Garlic cloves: Mince them fresh instead of using jarred, the difference in aroma when they hit the hot oil is worth the extra thirty seconds.
- Red and yellow bell peppers: The mix of colors makes the pot look alive, and their natural sweetness balances the heat from the spices beautifully.
- Diced tomatoes: I use canned because they are reliable and already broken down, which helps the sauce come together faster than fresh tomatoes ever could.
- Baby spinach: It wilts in seconds and adds a pop of green and freshness right at the end when everything else has melded together.
- Lemon: Slicing it and laying it over the fish while it cooks infuses everything with brightness, and the wedges at the table let everyone adjust to taste.
- Ground cumin: This is the backbone of the spice blend, earthy and warm, and it makes the whole dish smell like something you would find in a busy, happy kitchen.
- Smoked paprika: It adds a gentle smokiness that makes you think the dish took hours, even though it absolutely did not.
- Ground coriander: A little floral, a little citrusy, it rounds out the cumin and keeps the spice profile interesting.
- Cayenne pepper: Use it if you like a little tingle on your tongue, or skip it if you are cooking for people who reach for water at the first hint of heat.
- Salt and black pepper: Season generously because cod is mild and needs the support, and taste the sauce before adding the fish so you can adjust.
- Olive oil: Just enough to soften the onions and bloom the spices without making the dish feel heavy or greasy.
- Fish or vegetable stock: This is what turns the tomatoes into a sauce, so use something flavorful, not just water, and the difference will show.
- Fresh cilantro or parsley: A handful chopped and scattered on top makes the whole pot look vibrant and taste fresher, like you put in more effort than you did.
Instructions
- Warm the oil:
- Heat the olive oil in your largest skillet or Dutch oven over medium heat until it shimmers but does not smoke. You want it hot enough to soften the onion without browning it too fast.
- Soften the onion:
- Add the chopped onion and let it cook for three to four minutes, stirring occasionally, until it turns translucent and smells sweet. This is your foundation.
- Add the peppers and garlic:
- Stir in the minced garlic and diced peppers, letting them cook for another three minutes until the peppers start to soften and the garlic becomes fragrant. Do not let the garlic burn or it will taste bitter.
- Bloom the spices:
- Sprinkle in the cumin, smoked paprika, coriander, cayenne if using, salt, and black pepper, stirring everything together and cooking for one minute. The spices will wake up and fill your kitchen with warmth.
- Build the sauce:
- Pour in the diced tomatoes and stock, stirring to combine, then bring everything to a gentle simmer. Let it bubble quietly for eight to ten minutes until the vegetables are tender and the sauce thickens just a bit.
- Nestle the cod:
- Lower the cod fillets gently into the sauce, spacing them out so they cook evenly, then lay the lemon slices on top. Cover the pot and let it simmer for eight to ten minutes until the fish turns opaque and flakes easily when you press it with a fork.
- Wilt the spinach:
- Tuck the baby spinach into the sauce around the fish and let it cook for two minutes until it collapses into the pot. It will look like a lot at first but it shrinks fast.
- Serve and garnish:
- Spoon the fish and sauce into shallow bowls, scatter fresh herbs over the top, and tuck a lemon wedge on the side. Serve it hot while the sauce is still steaming.
Save on Pinterest One night I made this for my neighbor who had just come home from the hospital, and she told me it was the first meal that tasted like something again. I realized then that this dish does more than feed people. It reminds them that flavor and warmth still exist, even on hard days.
What to Serve Alongside
I almost always tear into a piece of crusty bread and use it to mop up every last bit of sauce, because letting that liquid gold go to waste feels wrong. Steamed rice works beautifully if you want something more substantial, and couscous soaks up the spices in a way that feels light and fluffy. Sometimes I just serve it in deep bowls with nothing else, and that is enough.
Swapping the Fish
Cod is my first choice because it holds its shape and has a mild flavor that lets the spices shine, but haddock, halibut, or even tilapia work just as well. I have used frozen fillets straight from the freezer in a pinch, just add an extra few minutes to the cooking time and make sure they are fully thawed before you nestle them in. The key is choosing something firm enough that it does not fall apart when you spoon it onto plates.
Storing and Reheating
Leftovers keep in the fridge for up to two days, and I reheat them gently in a covered pan over low heat so the fish does not dry out. The sauce thickens as it sits, so I sometimes add a splash of stock or water to loosen it back up. Do not microwave it on high or the cod will turn rubbery, low and slow is the way to go.
- Let the dish cool completely before transferring it to an airtight container.
- Reheat only what you plan to eat, because fish does not love being reheated multiple times.
- If the spinach looks sad the next day, stir in a handful of fresh greens when you reheat to brighten it up.

Recipe Questions & Answers
- → Can I use frozen cod fillets?
Yes, just make sure to thaw them completely and pat dry before adding to the pot to avoid excess moisture in the sauce.
- → What other fish works well in this dish?
Haddock, halibut, or any firm white fish are excellent substitutes. Adjust cooking time based on fillet thickness.
- → How do I know when the cod is properly cooked?
The cod is done when it turns opaque white throughout and flakes easily with a fork, typically after 8-10 minutes of simmering.
- → Can I make this ahead of time?
While best served fresh, you can prepare the vegetable base ahead and refrigerate. Add the cod just before serving for optimal texture.
- → What should I serve alongside this dish?
Crusty bread, steamed rice, couscous, or quinoa all pair beautifully to soak up the flavorful tomato-based sauce.
- → Can I adjust the spice level?
Absolutely. Omit the cayenne for mild flavor, or add chili flakes and extra cayenne for more heat to suit your preference.
