7 Easy Substitutes for Rainbow Trout
For each of these substitutes, we recommend preparing them in a similar way to how you would prepare rainbow trout. This will ensure that the flavors are complemented and not overpowered.
However, feel free to get creative and experiment with different cooking methods!
1 - Arctic Char
Arctic char is a fantastic pick if you're pining for the flavor of rainbow trout but can't find any. It's got that same delicate texture and mild taste that we all love.
Some even say it's like a cross between salmon and trout (both members of the Salmonidae family).
We love how easy it is to cook. It works well in a variety of dishes.
Grill it, bake it, or even toss it in a pan. You can use a 1:1 substitute ratio, so just follow your favorite trout recipe.
We've found it's a great way to switch things up without going too far off track; try it with side dishes for char siu pork.
2 - Salmon
The versatile superstar of the fish world, salmon is a go-to option if rainbow trout is MIA. Its rich, fatty texture and bold flavor set it apart.
We love how salmon can be grilled, baked, broiled-you name it, and it pairs nicely with side dishes for poached salmon.
It's strong.
Salmon has a stronger taste than trout, like a flavor party in your mouth (and it's higher in omega-3 fats). It's perfect if you enjoy something with more oomph.
We recommend a 1:1 substitute ratio for your favorite trout recipe.

3 - Catfish
The catfish is here and it's ready to sub in for your rainbow trout needs. Catfish has a firmer texture and a mild, sweet flavor (commonly channel catfish, Ictalurus punctatus).
It's perfect if you want something that holds up well to grilling or frying.
We found it works best with a 1:1 ratio, making it super easy to swap into your favorite trout recipe. Catfish is also great at soaking up flavors, so have fun with your marinades.

4 - Tilapia
The adaptable fish of our dreams, tilapia, is an easy catch in any store. It has a mild taste that makes it a fantastic blank canvas for flavors (a freshwater cichlid native to Africa).
We found tilapia to be especially versatile in cooking. Grill, bake, or pan-fry it, and you're good to go.
It's got a firmer texture but still delicate enough to please your palate.
Use a 1:1 substitute ratio for your trout recipes. It's less fatty than salmon but still delicious.

Steelhead trout is a solid pick if you're missing rainbow trout (the anadromous form of Oncorhynchus mykiss).
We found the texture to be firm yet tender. Perfect for grilling or baking.
It's awesome for anyone looking to keep the taste profile similar and it pairs well with sides for trout almondine.
We love using it in our favorite hearty dishes.
It's an easy switch that's super satisfying.
Steelhead trout is a crowd-pleaser in our kitchen. You won't even notice you're using a substitute.
6 - Mahi-Mahi
In terms of mixing up your fish game, mahi-mahi is an awesome call. It's got a firmer texture and a sweet, mild flavor (a tropical pelagic fish, Coryphaena hippurus).
We like how it holds up on the grill or in the oven.
Use a 1:1 substitute ratio for all your trout dishes. You'll love the rich taste it brings.
Grilling it gives an extra layer of flavor.
It's perfect for those who enjoy a touch of sweetness. For more splendid ideas, check our alternative fish to mahi-mahi article.
7 - Cod
Last but definitely not least, cod makes a stellar rainbow trout substitute. It's got a mild, slightly sweet flavor that's easy on the palate (a whitefish in the Gadidae family).
We love how it flakes beautifully, just like trout.
Cod is versatile, great for grilling, baking, or frying. Follow a 1:1 substitute ratio, and you'll be golden.
It's firmer, yet tender enough to soak up all the yummy seasonings you throw on it.
