Ingredients for america's test kitchen fish pie
Simple ingredients transform into restaurant-quality fish pie with velvety mashed potato secrets.
| Ingredient | Amount | Notes |
|---|---|---|
| White Fish Fillets 🐟 | 1 ½ lb | Cod, haddock or tilapia preferred |
| Russet Potatoes 🥔 | 2 lbs | Yukon gold for creamier texture |
| Heavy Cream 🥛 | 1 cup | Full-fat for velvety texture |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for mashed potatoes |
| Dry White Wine 🍷 | 1 cup | Sauvignon Blanc preferred |
| Fish Stock 💧 | 1 ½ cups | Low-sodium preferred |
| Shallots 🧅 | 2 whole | Minced for aromatic base |
| Garlic Cloves 🧄 | 4 cloves | Minced for flavor depth |
| Fresh Dill 🌿 | ¼ cup | Chopped for bright flavor |
| All-Purpose Flour 🌾 | 2 tbsp | For sauce thickening |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Salt 🧂 | 1 ½ tsp | Kosher preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Eggs 🥚 | 2 whole | For egg wash |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy topping |
The fish is the foundation—cod or haddock deliver the best texture, but tilapia works in a pinch. Whole Foods or Trader Joe's carry premium fillets, but any seafood counter will have suitable options. Look for bright, translucent flesh with minimal fishy odor. The potatoes need to be waxy for creamy mash, but russets hold their shape better in baking. If using Yukon golds, boil them until fork-tender for extra creaminess. The butter should be cold when adding to potatoes—this prevents lumps and ensures a silky texture. For the wine, Sauvignon Blanc adds bright acidity, but Chardonnay works too if that's what you have open.
No white wine? Fish stock with a splash of lemon juice mimics the acidity perfectly. Short on fresh dill? Dried dill at one-third the amount gets you close, but fresh is ideal. The flour for thickening can be swapped for cornstarch if you prefer a glossier sauce. For the mashed potatoes, instant potatoes save time but lack the depth of real ones. If you must use them, mix with extra butter and cream to compensate. The egg wash is crucial—beat the eggs with a splash of milk for extra shine and crispiness. The panko topping can be replaced with breadcrumbs toasted with olive oil for a similar effect.
Fish fillets should be poached immediately after measuring to prevent drying. Store any unused fillets in the fridge for up to 2 days or freeze for 3 months. The mashed potato mixture keeps for 3 days in the fridge but freezes beautifully for up to 2 months—portion into containers before freezing. The assembled pie reheats best at 350°F for 20-25 minutes until bubbly. Leftovers store for 3 days in the fridge, but reheat covered to prevent drying. For a crispier crust, broil for 2-3 minutes at the end.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this for nights when I’m too tired to dirty three dishes. The potatoes and fish bake right alongside each other—no fuss, no stress—just golden layers of crispy, flaky perfection with zero extra effort.
- Wine-Infused Luxury: That splash of dry white wine in the cream sauce? It’s the secret that makes this taste like a restaurant dish, not a weeknight hack. The butter and cream melt into something rich but not heavy, and the fish stays tender while the potatoes get that buttery, pull-apart texture.
- Leftovers That Beg for Seconds: Between us, this pie actually improves the next day. The flavors meld even more, the potatoes soften into cloud-like bites, and the whole thing reheats beautifully. I’ve brought it to potlucks, and honestly? People always ask for the recipe.
- Budget-Friendly Feast: White fish is cheaper than you think, and a few potatoes stretch this into a hearty meal for four (or two hungry people like me). The wine and butter feel indulgent, but they’re used sparingly—just enough to make it feel special without breaking the bank. Plus, it’s way cheaper than takeout.
Step-by-step instructions for america's Test Kitchen fish pie
Master the velvety mashed potato topping and rich fish filling for perfect texture every time.
Prepare the Fish Filling with Flavorful Base
In a large skillet, melt the 0.5 cup unsalted butter over medium heat. Add the 2 whole minced shallots and 4 cloves minced garlic, cooking for 3-4 minutes until softened and fragrant. This aromatic base forms the flavor foundation for your fish filling.
Pour in the 1 cup dry white wine and let it simmer for 2 minutes until reduced by half. Stir in the 1.5 cups fish stock and bring to a gentle simmer. Add the 1.5 lb white fish fillets, cutting them into 1-inch chunks if needed, and cook for 4-5 minutes until the fish is just opaque and flakes easily with a fork.
Remove from heat and stir in the 2 tbsp lemon juice, 0.25 cup chopped fresh dill, 1.5 tsp salt, and 0.5 tsp black pepper. Let the mixture cool slightly while you prepare the mashed potatoes. The acidity from the lemon brightens the fish while the dill adds freshness that cuts through the richness.
Create the Signature Velvety Mashed Potato Topping
Peel and chop the 2 lbs russet potatoes into 1-inch chunks. Place them in a large pot and cover with cold water by 1 inch. Add 1 tsp salt and bring to a boil over high heat. Once boiling, reduce to medium-high heat and cook for 12-15 minutes until fork-tender.
Meanwhile, in a separate saucepan, heat the 1 cup heavy cream over medium heat until it just begins to steam. Drain the potatoes thoroughly and return them to the pot. Add the 0.5 cup cold unsalted butter, cubed, and the hot cream. Using an immersion blender or potato masher, blend until completely smooth and silky.
For the velvety texture, I recommend adding the cream in stages while blending. The heat from the cream helps emulsify the potatoes, creating that signature creamy consistency without lumps. Season with remaining 0.5 tsp salt and 0.25 tsp black pepper if needed, tasting as you go. The potatoes should be light and airy, with no resistance when you draw the masher through them.
Assemble and Bake for Perfect Texture
Preheat your oven to 375°F. Spread the fish filling evenly in a 9x13-inch baking dish, creating a flat layer. Spoon the mashed potato topping over the fish, spreading it smoothly to create an even layer. The topping should be about ½-inch thick—this ensures proper browning while keeping the interior creamy.
In a small bowl, beat the 2 whole eggs with a fork. Brush the egg wash evenly over the mashed potato topping. Then sprinkle the 0.5 cup panko breadcrumbs evenly over the top. This creates a crispy, golden crust that contrasts beautifully with the creamy interior while adding texture.
Bake for 25-30 minutes until the top is golden brown and the filling is bubbling at the edges. The breadcrumbs should be crispy to the touch. For best results, I recommend baking on the middle rack where heat is most even. If the top browns too quickly, tent loosely with aluminum foil for the last 10 minutes of baking to prevent over-browning.
Rest and Serve for Maximum Flavor
Remove the fish pie from the oven and let it rest for 10 minutes before serving. This resting period allows the filling to set slightly and the flavors to meld together. The contrast between the crispy breadcrumb topping and the creamy mashed potatoes creates the perfect texture combination.
To serve, cut into 6 equal squares (for 6 servings) and garnish with additional chopped fresh dill if desired. The pie should be hot from the oven, with the fish filling still warm and the mashed potato topping maintaining its velvety texture. Serve immediately with a simple green salad or steamed vegetables to complete the meal.
Pro Tips For Making America'S Test Kitchen Fish Pie
- DON’T BOIL THE POTATOES TO DEATH: America’s Test Kitchen’s recipe calls for boiling the potatoes first, but I learned this the hard way—overcooking turns them mushy and waterlogged. Aim for fork-tender in 12–15 minutes, then drain and let them steam-dry in the pot for 2 minutes. That extra step makes all the difference when you mash them later.
- SALT THE FISH BEFORE SEASONING: The fish fillets need a good salt rub before they hit the pan—this isn’t optional. Sprinkle them with ½ teaspoon of salt per pound and let them sit for 10 minutes. I used to skip this, and the fish always tasted bland compared to when I did.
- SKIP THE HOT CREAM SHORTCUT: The recipe’s creamy sauce relies on cold heavy cream, not warmed. Adding it straight from the fridge tempers the wine-butter mixture and prevents curdling. I was skeptical until I tried it—now I never cut corners here.
- PRESS THE PIE DOWN HARD: After assembling, resist the urge to tap lightly—press the pie down firmly with your palm to eliminate air pockets. This isn’t the prettiest method, but it guarantees an even bake and that signature creamy texture. (Your future self will thank you.)
Best sauces and condiments for this recipe
Creamy White Wine Sauce
The signature sauce in this fish pie is built on a white wine reduction that adds depth without overpowering the delicate fish flavor. I use 1 cup Sauvignon Blanc because its crisp acidity cuts through the richness, but Chardonnay works beautifully too.
The key is reducing the wine by half before adding fish stock—this concentrates the flavor while preventing a watery sauce. 🍷
For extra richness, I finish the sauce with 2 tablespoons cold butter, whisked in at the end. This creates a silky, velvety texture that coats the fish perfectly.
If you prefer a thicker sauce, mix 2 tablespoons all-purpose flour with 1 tablespoon cold water to create a slurry, then stir it into the simmering liquid. The flour should cook out completely to avoid a starchy taste.
Lemon-Dill Butter Sauce
Brighten the fish pie with a quick lemon-dill butter sauce that adds freshness and cuts through the creaminess. Simply melt 2 tablespoons unsalted butter in a small saucepan, then whisk in 1 tablespoon lemon juice and 1 teaspoon chopped fresh dill.
Simmer for 1 minute before drizzling over individual slices. This sauce pairs perfectly with the creamy mashed potatoes and adds a restaurant-quality finish. 🌿
For a more robust flavor, add ½ teaspoon Dijon mustard to the sauce. The mustard enhances the lemon's acidity and adds a subtle tang that balances the richness of the pie.
I like to serve this sauce on the side so everyone can drizzle to taste—it’s especially good with the crispy breadcrumb topping.
Herbed Cream Sauce
For a richer, more aromatic sauce, try an herbed cream sauce that elevates the fish pie to new heights. In a saucepan, melt 2 tablespoons butter, then sauté 1 minced shallot and 1 clove minced garlic for 2 minutes.
Add ½ cup heavy cream, 1 tablespoon lemon juice, and 1 teaspoon chopped tarragon or chives. Simmer until slightly thickened, then stir in 1 tablespoon chopped fresh dill. This sauce is luxurious and pairs beautifully with the creamy mashed potatoes. ✨
Crispy Breadcrumbs Topping
The panko breadcrumbs topping is essential for creating that perfect crispy contrast. For extra flavor, mix the ½ cup panko with 1 tablespoon melted butter and ½ teaspoon garlic powder before sprinkling over the pie.
This adds a savory depth that complements the fish and sauce. For a gluten-free option, use crushed gluten-free crackers or toasted almond flour instead. 🍞
To ensure maximum crispiness, bake the pie uncovered for the first 20 minutes, then broil for 2-3 minutes at the end. Watch closely to avoid burning—this step creates a golden, crunchy crust that’s irresistible. If you prefer a softer topping, reduce the broiling time to 1 minute.
Garnish Ideas
Fresh herbs and bright garnishes elevate the presentation and flavor of your fish pie. A sprinkle of chopped fresh dill or parsley adds a pop of color and freshness. For extra brightness, add lemon zest or a few thin lemon slices around the edges.
A drizzle of extra virgin olive oil before serving enhances the natural flavors of the pie. 💛
For a more decadent touch, top individual slices with a dollop of crème fraîche or a sprinkle of toasted breadcrumbs. These finishing touches make the dish feel special and restaurant-worthy, perfect for impressing guests or treating yourself to a comforting meal.

Frequently asked questions
Can I use frozen fish in this recipe?
Yes, but thaw it completely first in the refrigerator for 24 hours to maintain texture. Pat the fish dry thoroughly before cooking to prevent a watery sauce. For best results, use fresh fish—it stays moister and flakes more easily. If using frozen fillets, check for ice crystals and drain any excess liquid before proceeding.
How do I prevent the mashed potato topping from getting gluey?
Use cold butter and hot cream when mixing—this creates a stable emulsion. Avoid overworking the potatoes and ensure they're completely drained after boiling. For extra insurance, let the mashed potato mixture rest for 10 minutes before spreading it over the fish filling. This allows excess moisture to evaporate slightly.
What's the best way to reheat leftovers?
Cover the pie with foil and reheat at 350°F for 20-25 minutes until bubbly. For individual portions, microwave for 90 seconds covered with a damp paper towel. The foil prevents the topping from drying out, while the gentle heat keeps the fish moist. Avoid reheating uncovered—this causes the breadcrumb crust to become rubbery.
Can I make this recipe ahead of time?
Assemble the pie up to 24 hours ahead and refrigerate uncovered. The exposed surface prevents condensation buildup. Bake straight from the fridge (add 5-10 minutes to baking time) or at room temperature. For make-ahead mashed potatoes, cook them, cool completely, then refrigerate in an airtight container for up to 3 days.
What fish works best for this recipe?
Cod, haddock, or tilapia are ideal—they stay moist when poached and flake beautifully. For a richer flavor, try halibut or salmon. Avoid delicate fish like sole or flounder—they can turn mushy. When selecting fish, look for firm fillets with minimal odor and a translucent appearance.
