Culver's Seafood Guide: Cod, Walleye & More

Culver's seafood options might surprise you. While this Wisconsin-born chain is famous for ButterBurgers and fresh frozen custard, it also serves up some of the Midwest's favorite fried fish — most notably North Atlantic cod and Wisconsin's beloved walleye. Whether you're observing Lent, skipping red meat, or just in the mood for something from the fryer that isn't beef, this guide walks you through the fish options, how they're served, and when they truly shine.

The Stars of the Show: North Atlantic Cod

The backbone of Culver's seafood lineup is its North Atlantic cod. The fillets are battered and fried to order, giving them that crackling golden crust that shatters with the first bite and reveals flaky, mild white fish inside.

Cod appears in a few different forms:

The cod dinner: A generous portion of battered cod served with sides of your choice. This is the pick for a hearty, sit-down style meal — the fish-and-chips of the Culver's world.
The fish sandwich: Cod tucked into a toasted bun with tartar sauce, lettuce, and often cheese. It delivers the same crispy satisfaction in a handheld format.
Lent-season specials: During the spring Lenten season, Culver's locations often spotlight their fish offerings, and some restaurants bring back extra seafood options or promotional combos.

The breading is the real draw here. It's seasoned just enough to be interesting on its own but neutral enough that a squeeze of lemon, a dash of malt vinegar, or a dip in tartar sauce takes it in whatever direction you like.

Wisconsin's Favorite: Walleye

If cod is the workhorse of the menu, walleye is the regional treasure. Walleye is a freshwater fish that's practically sacred in Wisconsin, where Friday fish fries are a cultural institution. Many Culver's locations — especially in the Midwest — serve walleye sandwiches and dinners, often as seasonal or regional offerings.

What makes walleye special:

Flavor: Walleye has a subtly sweet, clean taste that many people rank above cod for delicacy. It's the fish that makes Wisconsinites nod approvingly.
Texture: The fillets are typically thinner and flakier than cod, which means a higher crust-to-fish ratio in every bite. Crispy-fish lovers take note.
Availability: This is the catch (pun intended) — walleye is often seasonal or regional. Call ahead or check with your local restaurant if you're making a special trip for it. This is an independent guide and is not affiliated with Culver's.

When Seafood Shines: Lent Season

There's no better time to appreciate the fish menu than the Lenten season. In the weeks leading up to Easter, many customers swap their Friday ButterBurgers for a fish fry, and Culver's fish offerings hit their stride. Restaurants may run specials, extend availability of walleye, and generally give the seafood menu its moment in the spotlight.

A few tips for Lent-season ordering:

Order the dinner over the sandwich if you want the full Friday-fish-fry experience. Add coleslaw and a side of fries, and you've recreated the classic Midwest tavern plate.
Try the walleye if it's available — it's often a limited-time offering, and it sells out at some locations on busy Fridays.
Pair with lemon ice or a shake (more on that in our drinks guide) to complete the meal.

What the Fish Options Are Like: Taste and Texture

Here's an honest rundown of what to expect:

Cod: Mild, flaky, with a sturdy golden breading. The most widely available and consistent option. If you've had frozen fish sticks you liked, this is the grown-up version.
Walleye: Lighter, slightly sweeter, and flakier. More of a regional delicacy. When available, it's the connoisseur's pick.
Sandwiches vs. dinners: Sandwiches are portable and lunch-friendly; dinners give you more fish and let you mix and match sides. The breading holds up well in both formats, though a sandwich sitting in a to-go bag for a while will soften — eat it fresh for maximum crunch.

Building a Complete Seafood Meal

Want to make it a feast? Here's how to round out your fish order:

Classic pairing: Cod dinner + crinkle-cut fries + coleslaw. Tartar sauce on everything.
Lighter take: Fish sandwich + side salad or steamed broccoli (where available). You still get the crunch without the full fried spread.
Midwest authentic: Walleye dinner + mashed potatoes with gravy + rye bread (at locations that carry it). This is basically a Friday fish fry in restaurant form.

Prices and nutrition information may vary by location. Seafood meals at Culver's are generally priced in line with the premium burger dinners — expect the fish dinner to cost a bit more than a single-patty ButterBurger meal, roughly in the mid-range of the menu.

Dipping Sauces and Finishing Touches

The right sauce elevates fried fish from good to memorable. Tartar sauce is the default and the right call — creamy, tangy, and made for fried cod. Beyond that, consider asking for cocktail sauce if your location carries it; its horseradish kick is fantastic with walleye. A lemon wedge, when available, brightens the whole plate, and a few shakes of malt vinegar give the fries that authentic fish-and-chips character. Don't be shy about requesting extra tartar sauce — running out mid-meal is a tragedy.

For the sandwich crowd, a slice of American cheese melted over the cod fillet is a classic move that adds richness, and extra lettuce or tomato keeps things fresh. These small customizations cost little or nothing and make the fish options feel like your own.
