Ingredients for jamie oliver sweet pea fish pie

Flaky pastry, tender fish, and velvety peas come together in this British classic.

The fish is the heart of this dish—cod or haddock hold their shape beautifully when poached, but pollock works too. Look for fresh fillets with clear eyes and firm texture at your local fishmonger or grocery seafood counter. If using frozen, thaw in the fridge overnight for even cooking. The sweet peas should be bright green and tender—fresh is ideal, but high-quality frozen works perfectly. For the pastry, store-bought puff pastry saves time, but homemade all-butter pastry elevates the dish to restaurant quality. If making from scratch, use cold butter for flakiness and handle the dough minimally to avoid toughening.

No tarragon? Fresh dill or chives add brightness, though tarragon's anise notes are signature here. Running short on fresh herbs? Dried tarragon or dill at one-third the amount works, but fresh is always better. For the roux, don't rush the cooking—butter should foam before adding flour, or the sauce will taste raw. The milk should be full-fat for richness, but if you're using reduced-fat, add an extra tablespoon of butter to compensate. When assembling, chill the pie for 30 minutes before baking—this prevents a soggy bottom. The lemon zest adds brightness without overpowering, but if you're short, a splash of lemon juice works too.

This pie reheats beautifully—best served at room temperature after baking. Store leftovers in an airtight container for up to 3 days in the fridge, though the flavor peaks on day two. For freezing, bake the pie first, then wrap tightly in foil for up to 2 months. The pastry stays crisp when reheated in a 350°F oven for 15 minutes. For make-ahead prep, assemble the filling and refrigerate for up to 24 hours before adding the pastry. The herbs lose potency when frozen, so add fresh ones after thawing if possible.

Step-by-step instructions for jamie Oliver's sweet pea fish pie

Here's how to create a restaurant-worthy fish pie with tender fish, sweet peas, and a golden, flaky pastry top.

In a medium saucepan, melt the 0.5 cup unsalted butter over medium heat. Add the 3 cloves minced garlic cloves and sauté for 30 seconds until fragrant but not browned. This step builds the flavor foundation without overpowering the delicate fish.

Add the 1 cup sweet peas and cook for 2 minutes, stirring occasionally. Pour in the 1.5 cups vegetable stock and bring to a gentle simmer. Reduce heat to low and let it cook for 5 minutes until the peas are tender. Remove from heat and stir in the 2 tbsp chopped fresh tarragon, 1 tbsp lemon zest, and 0.25 cup chopped fresh dill. These herbs brighten the filling and balance the richness of the fish.

In a separate large skillet, melt the remaining 0.25 cup salted butter over medium heat. Add the 1.5 lb white fish fillets (cod or pollock work best) and cook for 2-3 minutes per side until the fish is just opaque in the center and flakes easily with a fork. Remove the fish and set aside.

In the same skillet, reduce heat to medium-low and whisk in the 0.5 cup all-purpose flour to create a roux. Cook for 1 minute until golden. Gradually whisk in the 1 cup whole milk until smooth. Simmer for 3-4 minutes until the sauce thickens to a velvety consistency. Season with 1.5 tsp sea salt and 0.5 tsp freshly ground black pepper. Return the fish to the sauce and gently fold in the pea mixture. Let it warm through for 2 minutes—this ensures the filling is piping hot when assembled.

In a large bowl, combine the 2 cups all-purpose flour and 1.5 tsp sea salt. Cut in the 0.25 cup salted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. Gradually add the 0.5 cup ice water, 1 tablespoon at a time, mixing gently with a fork until the dough just comes together. Avoid overworking it—this keeps the pastry tender and flaky.

Turn the dough onto a lightly floured surface and knead it 6-8 times until smooth. Wrap it in plastic wrap and chill in the refrigerator for 30 minutes. This resting period relaxes the gluten, making it easier to roll out and ensuring a crisp, golden finish. Preheat your oven to 400°F while the dough chills.

Transfer the pea and fish filling to a 9x9-inch baking dish and spread it evenly. Roll out the chilled pastry dough on a lightly floured surface to a 1/8-inch thickness. Cut a circle slightly larger than the top of the baking dish, then carefully lift it and place it over the filling. Trim any excess dough with a sharp knife, leaving a 1/2-inch border. Fold the edges of the pastry under and crimp them with a fork to seal.

Brush the pastry with a beaten egg (optional but recommended for extra shine) and bake for 25-30 minutes until the pastry is golden brown and the filling is bubbling at the edges. The pie is done when the pastry is crisp and the internal temperature reaches 165°F—this ensures the filling is hot and the pastry is perfectly cooked. Let it rest for 10 minutes before serving to allow the juices to redistribute and the pastry to set.

Slice the pie into 4 equal servings and serve immediately with a side of steamed green beans or a simple salad. The contrast of the flaky, golden pastry with the creamy, herby pea and fish filling makes every bite unforgettable. The secret to success lies in the balance of flavors—sweet peas, tender fish, and the bright herbs—and the crisp, buttery pastry that seals in all the goodness.

Perfect pairings for this dish

Herb-Infused Sides

Fresh mint and pea shoots tossed with lemon vinaigrette (2 tbsp olive oil, 1 tbsp lemon juice, 1 tsp honey) brighten the rich fish pie beautifully. I grab these at my local Portland farmers market—they add a fresh, bright contrast to the creamy filling.

For a heartier option, try buttery mashed potatoes with roasted garlic and chives, which soak up any extra sauce. 🌿

Crisp Vegetable Accompaniments

Blistered green beans with slivered almonds and a pinch of flaky sea salt provide the perfect textural contrast. I roast them at 425°F for 12 minutes until charred, then finish with a splash of rice vinegar for acidity. Another favorite is shaved fennel salad with blood orange segments—its anise notes complement the tarragon in the pie. 🍋

Beverage Pairings

A crisp Sauvignon Blanc from New Zealand—like Kim Crawford's Sauvignon Blanc—cuts through the richness with its citrus and herbal notes. For beer lovers, a Belgian witbier (try Stella Artois' Witbier) offers a refreshing, spicy contrast.

I also love serving this pie with sparkling elderflower lemonade—the effervescence cleanses the palate between bites. 🍷

Cheese Course Extension

Add a goat cheese and honey crostini platter before serving the pie. Top toasted baguette slices with herb-infused goat cheese (mix with chopped dill and lemon zest) and drizzle with local honey.

The tangy, creamy contrast prepares your palate for the pie's richness. I source my goat cheese from a nearby farm stand in Portland. 🧀

Dessert Harmony

Finish the meal with lemon posset—its silky texture and bright citrus echo the lemon zest in the pie. For something lighter, honeycomb ice cream with crushed pistachios adds crunch and sweetness. I often make my posset with local Pacific Northwest lemons for that extra zing. 🍋

Make-Ahead Pairing Prep

Prep sides the night before: marinate the green beans in their dressing, chop all salad ingredients, and store them in airtight containers. For the crostini, assemble the cheese topping but skip the honey until serving—this keeps everything fresh.

The pie itself can be prepped ahead and baked just before guests arrive. ✨
