This miso butter cod may seem like an odd flavor combination but it actually is one of those flavor combinations that make you go, “wow, that really did work.”
The miso is salty and the butter gives it a smooth, milky flavor. Together, they make this miso butter cod so much more than what you typically get from a piece of cod.
It’s perfect for a delicate fish like cod because since cod is light in flavor, it can take the miso butter on top.
I have always been intrigued with miso and using it in recipes.
Besides using it in the classic miso soup, there are a multitude of ways to use miso and I’m still exploring more ways!
It has a nutty and complex flavor and there are many varieties of it.
I really love that this miso butter cod comes together in a foil packet.
Literally your entire dinner can be made in this foil packet in the oven.
Incredibly easy clean up, too!
What is cod?
It’s a lean, delicate, and flaky white fish.
Cod has a somewhat sweet flavor but not like dessert sweet.
It just doesn’t taste as fishy as other fish.
Can I use another type of fish?
I would highly recommend cod but you can use another light, flaky white fish if you can’t find cod.
Can I use frozen?
You can, but just thaw it beforehand.
How do you know the cod is done cooking?
Cod takes virtually no time to cook. Generally about 10 minutes.
Once you see the top of the cod start ‘flaking’ or breaking up, that is when it’s done.
What is the texture of cod?
Flaky, delicate, soft, and buttery smooth.
What is miso?
Miso is a salty and savory traditional Japanese seasoning produced by fermenting soybeans with other ingredients. It gives food a lot of umami!
Is there a substitute for miso?
There is no substitute for miso.
Can I use white miso?
Yes, but the flavor of white miso vs. red miso can be drastically different so just understand that when making this dish. It will still taste awesome but it will be different than what I intended the dish to be.
Can I use salted butter?
No. Unsalted butter is best in this dish because the miso is already so salty that adding unsalted butter will make your dish saltier.
Is there a substitute for butter?
Not for this particular dish.
I don’t like cooking with foil, is there an alternative?
You can use parchment paper but you might want to use several layers since the fish will have a lot of liquid and your parchment paper may tear and leak out.
What do you serve with this?
You can serve this with whatever vegetable you like but I really like serving this with asparagus because it’s one of the relatively quicker and easier vegetables to cook in 10 minutes.
Since the vegetable should cook with the cod in the foil packet, asparagus is the best choice!
The easiest dinner that comes together in little foil packets! Virtually no clean up and dinner on the table in less than 20 minutes!
- 1 tablespoons red miso paste
- 3 tablespoons unsalted butter, room temperature
- 1 teaspoon dark brown sugar
- 2 pounds fresh cod
- 3/4 pound fresh asparagus, washed and ends trimmed
Preheat oven to 400 degrees Fahrenheit and prepare two large pieces of aluminum foil and a baking sheet.
In a small bowl, mix together miso, butter, and dark brown sugar.
Pat dry cod then place each piece on its own piece of foil.
Place miso butter mixture on top of cod and gently spread around with your fingers (see photo).
Put asparagus next to the cod, sprinkle salt on the asparagus then wrap the foil so the ends are sealed and so is the top (see photo).
Repeat for the other piece of cod and remaining miso butter and asparagus.
Place the foil packets onto the baking sheet and bake for 10 minutes then remove from oven. Let the foil packets rest for 5 minutes, wrapped.
Carefully open the foil packets and serve directly from the foil packets on a plate!
