Pressed Ceviche Recipe (Aguachile Style with Crispy Potato Hay)

Lately I’ve been obsessed with pressing things in a tortilla press.

I’ve pressed sandwiches. I’ve pressed all kinds of things. So naturally, I started wondering what would happen if I pressed fish.

Turns out, it’s a really fun way to make ceviche.

Instead of slicing your fish and piling it into the center of a plate, pressing it spreads the fish across the entire surface area. Every bite gets dressed with aguachile, cilantro oil, jalapeños, pickled onions, and crispy potato hay. It eats almost like a cross between ceviche and a crudo.

This dish is heavily inspired by where I’m from.

I grew up in South Texas right on the border of Mexico and the Gulf. We had South Padre Island, fresh seafood, Mexican food everywhere, and ceviche was just part of life. I ate a lot of it growing up and made plenty of it while working in restaurants.

Living in Seattle gives me access to some incredible sushi-grade fish, so for this version I used bluefin tuna and Japanese amberjack. You could absolutely make this with red snapper, which is what I grew up eating, or any flaky white fish you trust enough to serve raw.

The bright cucumber aguachile, spicy jalapeño, pickled onion, and crispy potato hay make this one of my favorite summer seafood dishes I’ve made in a long time.

How to Make Pressed Ceviche

Step 1: Make the Crispy Potato Hay

Place the water and rice wine vinegar into a bowl.

Using a Benriner mandolin fitted with the fine julienne attachment, shave the russet potato directly into the water bath.

The vinegar helps keep the potato bright while the water rinses away excess starch.

Let the potato sit for a few minutes.

Instead of pouring everything through a strainer, lift the potato directly from the water. This keeps the starch settled at the bottom.

Transfer to paper towels and dry thoroughly.

Heat neutral oil to: 350°F (177°C)

Fry in very small batches.

This is important. Potato hay goes from golden brown to burnt incredibly fast.

Cook until deep golden brown and crisp.

Transfer to paper towels and season immediately with salt.

Spread onto a sheet tray to cool.

For extra crunch, place in a 170°F oven for 10 to 15 minutes to dry further.

Step 2: Make the Aguachile

Place a fine mesh strainer over a bowl.

Grate the cucumbers over the strainer.

Next, grate the jalapeño over the same strainer.

Allow the liquid to drain naturally.

You should end up with roughly:

  • 360 g liquid (about 1½ cups)

Season with:

  • Lime juice
  • Salt

Taste and adjust.

The flavor should be bright, fresh, spicy, and slightly salty.

Step 3: Make the Cilantro Oil

Add to a blender:

  • Cilantro
  • Spinach
  • Neutral oil
  • Pinch of salt

Blend on high for approximately 5 minutes.

The mixture should become warm and vividly green.

Transfer to a food-safe piping bag.

Hang the bag and allow gravity to separate the oil from the solids.

Once separated, strain and reserve.

You should be left with a vibrant green cilantro oil.

Step 4: Press the Fish

Place sheets of parchment paper into a tortilla press.

Arrange the fish slices in an overlapping pattern.

I used:

  • 2 oz tuna
  • 2 oz amberjack

per plate.

Fold the parchment over the fish.

Press gently.

You’re not trying to smash it into oblivion. You’re just creating a thin sheet that covers the plate.

Transfer carefully to a chilled serving bowl or plate.

Step 5: Assemble

Spoon a generous amount of aguachile around and over the fish.

Add a spoonful of cilantro oil.

Scatter over:

  • Jalapeño slices
  • Pickled onions
  • Cilantro

Finish with a generous pile of crispy potato hay.

Season with flake salt.

Serve immediately.

Tips for Success

Use Sushi-Grade Fish

Since the fish is served raw, buy from a trusted seafood source.

Chill Your Plate

Cold plates help keep the fish firm and refreshing.

Dry the Potatoes Thoroughly

Wet potatoes create splattering oil and soggy potato hay.

Don’t Overdress

The fish should still be the star. Think ceviche, not soup.

Frequently Asked Questions

What fish is best for ceviche?

Red snapper is traditional in many ceviche recipes. For this version I love bluefin tuna, amberjack, hamachi, halibut, and other sushi-grade fish.

What is the difference between ceviche and aguachile?

Ceviche is typically cured in citrus juice. Aguachile uses a seasoned liquid, often made with lime, chiles, cucumber, herbs, or other fresh ingredients and is usually served immediately.

Can I make the potato hay ahead of time?

Yes. Store it uncovered at room temperature for a few hours or in a low oven to keep it crisp.

Can I make the cilantro oil ahead?

Absolutely. Store it in the refrigerator for up to several days.

Final Thoughts

This recipe hits a lot of things I love in one dish.

It’s rooted in the ceviche I grew up eating in South Texas, but it also takes advantage of the incredible seafood available here in Seattle. The pressing technique is fun, the presentation is beautiful, and the crispy potato hay adds something unexpected that makes people stop and ask what they’re eating.

If you’re looking for a summer seafood recipe that feels restaurant-worthy without being complicated, this pressed ceviche is hard to beat. The combination of tuna, amberjack, cucumber aguachile, cilantro oil, jalapeño, pickled onion, and crispy potato hay is bright, refreshing, crunchy, and exactly what I want to eat when the weather gets warm.

  • Season the aguachile with lime juice and kosher salt. Taste and adjust as needed. The finished aguachile should taste bright, fresh, spicy, and lightly seasoned.
  • Add the cilantro, spinach, neutral oil, and a pinch of salt to a blender. Blend on high speed for approximately 5 minutes until the mixture becomes warm and vividly green.
  • Transfer the blended mixture to a piping bag or fine strainer setup and allow the oil to separate naturally from the solids. Strain and reserve the bright green cilantro oil.
  • Place sheets of parchment paper inside a tortilla press. Arrange slices of sushi-grade fish in an overlapping pattern. Press gently to create a thin, even layer of fish without tearing it.
  • Carefully transfer the pressed fish to chilled serving plates or bowls.
  • Spoon the cucumber aguachile around and over the fish. Drizzle with cilantro oil.
  • Scatter the pressed ceviche with sliced jalapeños, pickled red onions, and fresh cilantro.
  • Finish with a generous mound of crispy potato hay and season with flake salt.
  • Serve immediately while the fish is cold and the potato hay remains crisp.

Notes

Always use sushi-grade fish from a trusted seafood source since this pressed ceviche is served raw. Bluefin tuna and amberjack are excellent choices, but hamachi, halibut, rockfish, and red snapper work beautifully as well.
Chill your serving plates before assembling the dish. Cold plates help maintain the delicate texture of the fish and keep the ceviche refreshing from the first bite to the last.
Dry the julienned potatoes thoroughly before frying. Excess moisture can cause oil splatter and prevent the potato hay from becoming light and crispy.
When dressing the fish, resist the urge to overdo the aguachile. The cucumber-lime broth should enhance the seafood rather than overpower it. Think of this dish as a balance between ceviche and aguachile, where the fish remains the star.
The crispy potato hay can be made several hours ahead and stored uncovered at room temperature or kept warm in a low oven to maintain its crunch. The cilantro oil can also be prepared in advance and refrigerated for several days, making this an ideal recipe for entertaining.
