Fish Friday

On Fish Fridays, your plate carries more than dinner; it carries centuries of politics, piety, and the occasional royal power move.

From royal policy to parish fish fry.  In 1563, Elizabeth I’s chief adviser, William Cecil, pushed Parliament to bring back strict “fish days,” not to make England holier, but to make it stronger at sea.

The Reformation had relaxed many Catholic fast-day rules, people were eating more meat on traditional fish days, and England’s fishing industry—and with it, its pool of experienced sailors—was shrinking.

Cecil’s idea was simple: mandate abstinence from meat on Wednesdays, Fridays, and Saturdays, and you force the kingdom to eat more fish, supporting coastal economies and keeping the navy’s future recruits in constant practice.

He even spelled it out: “Let the old course of fishing be maintained by the straitest observations of fish days… so the sea coasts should be strong with men and habitations and the fleet flourish more than ever.”

These Elizabethan laws were framed explicitly as economic and political rather than devotional; Cecil added a note reassuring more Puritan-minded Protestants that the measure was not a return to “popish” superstition but national policy.

Still, the effect looked remarkably similar to the old medieval pattern: on certain days, the English table turned from beef and mutton to cod, herring, and whatever “counted” as fish, from carp to porpoise.

Catholic “Fish Friday,” by contrast, is older and more spiritual in origin. For centuries Christians marked Friday as a weekly remembrance of Christ’s crucifixion, choosing small acts of penance like abstaining from the warm‑blooded meat associated with feasting and celebration.

The Church drew a symbolic line between land animals and fish; flesh from warm‑blooded creatures was off the table on fast days, while fish, as cold‑blooded and less “festive,” was permitted.

Over time, this discipline spread widely: in much of Europe, Friday became a fish day as naturally as Sunday was a feast day.

Modern Catholics in the United States are now obliged to abstain from meat on Ash Wednesday and the Fridays of Lent, while outside Lent they are still called to do some form of Friday penance, with many choosing to keep the old fish‑on‑Friday tradition year‑round.

Along the way, that simple rule reshaped food culture: church fish fries in the Midwest, seasonal fast‑food fish sandwiches, and family tables where tuna casseroles, salmon patties, or shrimp boils marked the end of the week.

The myth that some medieval pope mandated fish to bail out Italian fishmongers is persistent, but Catholic historians point out that the real example of policy‑driven fish eating comes from Elizabeth I’s England, not Rome.

So when you sit down to a Fish Friday dinner—whether in a parish hall in Tennessee or your own kitchen—you’re at the crossroads of these stories: a queen using fish to build a navy, a Church using abstinence to shape a weekly spiritual rhythm, and generations of cooks figuring out how to make those meals not just dutiful, but delicious.

A modern Fish Friday menu

For this Fish Friday blog, we’ll build a simple, balanced plate:

Sesame‑seared ahi tuna, sliced and served warm

Steamed rice, fluffy and lightly seasoned

A bright Japanese‑style cucumber salad (sunomono) for crunch and acidThis trio nods to Japanese flavors while still feeling at home on an American weeknight table, especially in a place like Tennessee where fish fries, Lent, and Friday seafood specials all overlap in local food culture.

Sesame-seared ahi tuna with citrus-soy drizzle

This recipe gives you a restaurant‑style sear: deeply browned sesame crust on the outside, tender and rosy in the center.

Ingredients (serves 2–3)

2 ahi tuna steaks, about 6–8 oz each, 1–1.5 inches thick, sushi‑grade if serving very rare

2 tablespoons soy sauce (or tamari)

1 tablespoon fresh lemon or lime juice

1 teaspoon toasted sesame oil

2 tablespoons neutral high‑heat oil (avocado, canola, or grape seed)

3 tablespoons of sesame seeds (white, black, or a mix)

1 teaspoon garlic powder

3/4 teaspoon kosher salt, plus more to taste

1 teaspoon of freshly ground black pepper

Optional garnish:

1–2 green onions, thinly sliced

A handful of cilantro leaves

Sriracha mayo (mix mayonnaise with sriracha to taste) or extra soy + citrus

Instructions

Whisk the marinade.
In a small bowl, whisk the soy sauce, citrus juice, sesame oil, garlic powder, about 1/4 teaspoon of the salt, and several grinds of black pepper.

This marinade is bold but brief; it perfumes the outside of the fish without “cooking” it like a long soak would.

Marinate the tuna lightly.

Pat the tuna steaks dry and lay them in a shallow dish.

Pour the marinade over, turning to coat all sides.

Cover and refrigerate for 10–20 minutes while you prep the rice and cucumber salad.

Flip once halfway through so both sides take on flavor.

Prepare the sesame crust.

On a plate, combine the sesame seeds, remaining salt, and the rest of the black pepper.

When the tuna comes out of the marinade, let excess drip off, then roll each steak in the sesame mixture, pressing gently so the seeds cling to every surface.

Heat the pan until very hot.

Set a heavy skillet (cast iron or stainless) over medium‑high to high heat and add the neutral oil.

When the oil shimmers and just begins to wisp smoke, the pan is ready.

A hot pan is crucial for a crisp crust and rare center.

Sear the ahi.
Gently lay the tuna steaks in the pan. Sear for about 45–60 seconds on the first side without moving them, until the sesame is golden and fragrant.

Flip and sear another 45–60 seconds for rare, or up to 90 seconds per side for medium‑rare; you can briefly sear the edges by holding the steaks with tongs.

The center should still feel soft when you press it with a finger.Rest and slice.
Transfer the tuna to a cutting board and let it rest for 2–3 minutes. Using a sharp knife, slice across the grain into 1/4–1/2‑inch slices.

Taste a piece and adjust with a sprinkle of salt or a few drops of soy if needed.Plate.
Fan the slices over a bed of hot rice or alongside the cucumber salad. Sprinkle with green onion and cilantro, and drizzle with a bit of sriracha mayo or reserved citrus‑soy for color and heat.

Steamed rice for Fish Friday

This rice is intentionally simple so it soaks up the juices from both tuna and salad.

Ingredients

1 cup jasmine or short‑grain white rice

1 1/4 to 1 1/2 cups water (check your rice type)

1/4 teaspoon salt

Optional: 1 teaspoon rice vinegar and 1/2 teaspoon sugar for a subtle sushi‑rice vibe

Instructions

Rinse the rice.
Place the rice in a bowl, cover with cold water, swish, and drain; repeat 2–3 times until the water is less cloudy. This removes excess starch and keeps the grains from clumping.

Cook.
Add rinsed rice, measured water, and salt to a small pot. Bring to a gentle boil, then cover, reduce heat to low, and cook for 12–15 minutes without lifting the lid, until water is absorbed.

Steam off heat.
Turn off the heat and let the rice sit, covered, for 10 minutes. If using vinegar and sugar, warm them together just enough to dissolve, then gently fold through the rice with a fork.

Fluff.
Fluff with a fork and keep covered until you’re ready to plate under your tuna.

Bright Japanese-style cucumber salad (sunomono)

This salad gives you crunch, acid, and a bit of sweetness—perfect against the rich tuna and plain rice. It’s inspired by Japanese sunomono, a simple vinegar‑dressed cucumber dish that often appears alongside fish.

Ingredients (serves 2–3)

1 large English cucumber, or 2 small Japanese/Persian cucumbers

1/2 tablespoon salt, divided

1/2 tablespoon sugar (or a bit more to taste)

2 tablespoons rice vinegar

2 teaspoons soy sauce

1 teaspoon toasted white sesame seeds

Optional add‑ons (feel free to pick one for variety, especially if this is the only side):

A few pieces of wakame seaweed, rehydrated and chopped

A small handful of thinly sliced red onion

A few radish rounds for extra color

Instructions

Slice and salt the cucumbers.
Thinly slice the cucumbers into coins using a knife or mandoline.

Place in a bowl, sprinkle with about 1/4 tablespoon of the salt, toss, and let sit 5–10 minutes to draw out water.

Drain and squeeze.
Transfer cucumbers to a colander, rinse briefly to remove excess salt, then squeeze handfuls firmly to remove as much liquid as possible.

This step is key to getting a crisp, not watery, salad.

Make the dressing.

In a small bowl, whisk together rice vinegar, sugar, soy sauce, and the remaining pinch of salt until the sugar dissolves.

Taste: it should be bright, lightly sweet, and pleasantly salty; adjust sugar or vinegar to your liking.

Combine.

Add the cucumbers (and any optional wakame, onion, or radish) to the dressing and toss gently to coat.

Let sit 5–10 minutes so the flavors meld.Finish.
Sprinkle with toasted sesame seeds just before serving.

Serve chilled or at cool room temperature alongside the tuna and rice.Bringing the stories to the table.

When you put this Fish Friday plate together—seared ahi, steamed rice, and a tangy cucumber salad—you’re quietly stitching together several food histories at once. The ahi and rice lean toward Japanese flavors, where a simple set meal might pair grilled or seared fish, plain rice, and a vinegar‑bright vegetable dish much like this sunomono.

The Friday abstinence itself, though, traces back to Christian communities marking the crucifixion with a small but regular sacrifice, choosing fish instead of meat as an embodied weekly prayer.

In Tudor England, those habits became raw material for national strategy, as Elizabeth I’s ministers turned “fish days” into a tool to keep fishermen working and sailors ready for conflict at sea.

In modern America, they’ve morphed again into parish fish fries, school cafeteria menus, and home traditions where families know, almost instinctively, that Friday dinner should look a little different.

Cooking a Fish Friday meal like this one lets you participate in that long, evolving story—only now, your abstinence can be generous rather than grim. Instead of a plain piece of boiled fish, you get crackling sesame crust, jewel‑bright slices of tuna, rice that catches all the juices, and cucumbers that snap like a palate cleanser between bites. Whether you’re observing Lent, keeping a weekly rhythm, or just leaning into a good story as you cook, this plate gives you both: history on the page and hospitality on the plate.
