7 Easy Substitutes for Flounder

There are plenty of delicious substitutes that will satisfy your craving for a delicate and flaky white fish. Here are seven easy options:

1 - Cod

Our first choice has got to be cod (Gadus morhua).

Cod has a similar mild, slightly sweet flavor and that same delicate flakiness when cooked. Perfect for a 1:1 ratio swap.

A bit firmer than flounder, it holds up well to baking, frying, or poaching. Can we talk about how versatile cod is?

It's readily available and easy on the wallet. Craving more fishy knowledge?

Check out these cod fish substitutes and breaded cod side dish ideas.

2 - Tilapia

Next up, tilapia! It's an excellent choice for flounder lovers.

Tilapia (often farmed Nile tilapia, Oreochromis niloticus) is budget-friendly and super easy to find.

We've got to mention the taste-mild and slightly sweet, making it a great 1:1 swap for flounder in almost any recipe. Its delicate, flaky texture is a hit too.

Just a heads-up, tilapia is a bit more delicate when cooking, so handle it with care. It's inexpensive and widely available, so it's a win-win!

3 - Halibut

Tilapia not your thing? How about giving halibut a shot?

It's heartier and has a richer, meatier flavor (richer and slightly buttery) compared to flounder.

Halibut is perfect for grilling, broiling, or pan-frying. Its firm, meaty texture is a winner in our book.

Use it in a 1:1 ratio as a flounder substitute. We love its mild, slightly sweet flavor.

Heads up, it's a bit pricier, but worth it for a special meal.

Find more ideas for halibut swaps in our halibut substitutes guide.

4 - Rainbow Trout

Then there's rainbow trout, our go-to when flounder's off the table. It's got this mild, slightly nutty flavor that we love.

The texture is flaky and tender, perfect for our palate.

Use it in a 1:1 ratio with flounder. Just be careful cooking; it's a bit delicate, like a sensitive friend.

Rainbow trout (a cold-water salmonid, Oncorhynchus mykiss) is loaded with healthy omega-3s, our secret weapon for a balanced diet.

5 - Sole

Sole is like the unicorn of fish-hard to find but worth the hunt! If you can't get flounder, lemon sole (Microstomus kitt) or Dover sole (Solea solea) are your next best bet.

They've got that mild, slightly sweet flavor that we totally dig.

Their delicate, tender texture makes them perfect for recipes needing a gentle touch.

Use them 1:1 with flounder, no math needed. Because they're so delicate, stick to poaching or steaming-anything rougher, and they might fall apart.

They can be a bit pricey and tricky to find in stores.

For more alternatives, check our detailed guide on sole fish substitutes.

6 - Haddock

Why go for haddock? This fish is cod's close cousin (Melanogrammus aeglefinus) and nails it as a flounder substitute.

It's got a slightly sweeter flavor and flakier texture that's perfect for our recipes. We use a 1:1 ratio with ease.

Haddock shines in baking, broiling, or frying. We love its mild, slightly sweet taste and tender texture.

Plus, it's usually easy to find and doesn't break the bank.

7 - Catfish

Even if catfish isn't your first choice, it's an awesome flounder substitute. We love its mild, slightly sweet flavor.

The texture is delicate but firm enough for frying or baking, with fine flakes and faintly earthy-sweet notes.

It's great in any recipe that calls for flounder. Just swap it in a simple 1:1 ratio.

This fish is budget-friendly and easy to find.

The firmness makes it perfect for all sorts of cooking methods. Plus, it gets delightfully flaky when cooked.
