Ingredients for campbell's soup fish pie

Sixteen ingredients transform a simple Campbell's Soup Fish Pie into restaurant-quality comfort food.

Ingredient Amount Notes
Campbell's Cream of Celery Soup 🍲 2 cans 10.5 oz each, unsalted preferred
Campbell's Cream of Potato Soup 🥔 1 can 10.5 oz, optional for extra creaminess
White Fish Fillets 🐟 1 ½ lb Cod or haddock, skinless, cut into chunks
All-Purpose Flour 🌾 2 tbsp For fish coating, fine texture
Unsalted Butter 🧈 ½ cup European-style preferred for richness
Heavy Whipping Cream 🥛 ½ cup Full-fat for velvety texture
Russet Potatoes 🥔 2 lb Yukon Gold for creamier mash
Milk 🥛 ½ cup Whole milk for creamier potatoes
Salt 🧂 1 ½ tsp Diamond Crystal kosher preferred
Black Pepper 🌶️ ½ tsp Freshly cracked for aroma
Fresh Parsley 🌿 ¼ cup Chopped, for garnish
Puff Pastry Sheet 🍰 1 sheet Thawed, for golden crust
Large Egg 🥚 1 whole Beaten, for pastry brush
Extra-Virgin Olive Oil 🫒 2 tbsp For sautéing fish
Garlic Cloves 🧄 3 cloves Minced, for fish seasoning

The fish selection is critical—cod or haddock delivers that delicate, flaky texture that holds up perfectly in the pie. Whole Foods or Trader Joe's carry high-quality frozen fillets, but fresh is ideal if you're near a seafood market. Look for fillets with minimal bruising and a clean, oceanic aroma. The Campbell's soups form the creamy base, but low-sodium versions prevent over-salting. For the mashed potatoes, Yukon Golds

No cod? Tilapia or pollock work equally well, but avoid flaky fish like salmon that may disintegrate. Substituting cream of mushroom soup for one of the Campbell's cans adds depth, though the celery flavor remains essential. For a richer mashed potato topping, add 2 oz cream cheese to the butter before mixing. Fresh parsley can be swapped for dried parsley at one-third the amount, but the fresh variety brightens the dish. The puff pastry can be replaced with shortcrust pastry for a more rustic finish, though it won't achieve the same golden flakiness. Always thaw frozen puff pastry in the fridge overnight for even baking.

Store the mashed potato mixture in an airtight container with plastic wrap pressed directly on the surface to prevent drying. It keeps for 3 days in the fridge and freezes beautifully for 3 months. Assemble the pie just before baking to maintain the pastry's crispness—pre-assembled pies can get soggy. The finished dish reheats well in a 350°F oven for 15 minutes, covered with foil. For a make-ahead option, bake the pie, cool completely, then refrigerate. Reheat covered with foil to preserve moisture, then broil briefly for a crispy top.

Step-by-step instructions for Campbell's soup fish pie

Here's how to assemble this creamy, comforting dish with rich layers and golden pastry.

1

Prepare the Creamy Fish Filling

In a large skillet, heat the 2 tablespoons extra-virgin olive oil over medium heat. Add the 1.5 lb white fish fillets cut into chunks and cook for 3-4 minutes until they turn opaque and begin to flake easily. Remove from heat and set aside.

In the same skillet, add the 3 minced garlic cloves and sauté for 30 seconds until fragrant. Pour in the 2 cans Campbell's Cream of Celery Soup and 1 can Campbell's Cream of Potato Soup, stirring to combine. Bring to a gentle simmer and cook for 5 minutes to let the flavors meld.

Transfer the soup mixture to a mixing bowl and stir in the 0.5 cup heavy whipping cream and 0.5 cup unsalted butter. Season with 1.5 teaspoons salt and 0.5 teaspoon black pepper. Return the cooked fish to the mixture and fold gently to distribute evenly. Keep warm while you prepare the mashed potatoes.

2

Make the Creamy Mashed Potato Topping

Peel and dice the 2 lb russet potatoes into 1-inch cubes. Place them in a pot of cold water and bring to a boil. Cook for 15-20 minutes until fork-tender, then drain thoroughly.

Return the potatoes to the pot and add the 0.5 cup milk and 0.5 cup unsalted butter. Mash until completely smooth, adding more milk if needed for a creamy consistency. Season with 0.5 teaspoon salt and 0.25 teaspoon black pepper. Transfer to a serving bowl and set aside.

Spread the mashed potatoes evenly over the fish filling in a 9x13-inch baking dish, creating a smooth, even layer. This will form the creamy base beneath the pastry crust.

3

Assemble and Bake the Fish Pie

Preheat your oven to 375°F. Unfold the 1 sheet puff pastry sheet on a lightly floured surface and gently press it to even out any thickness. Brush the entire surface with the beaten 1 whole large egg using a pastry brush.

Carefully lift the pastry and drape it over the mashed potato layer, pressing lightly to seal any edges. Trim excess pastry with a sharp knife, leaving about ½-inch border. Cut decorative slits in the top to allow steam to escape.

Place the baking dish on a parchment-lined sheet pan and bake for 35-40 minutes until the pastry is golden brown and the filling is bubbling at the edges. The internal temperature should reach 165°F when checked with an instant-read thermometer.

4

Finish and Serve

Remove the fish pie from the oven and let it rest for 10 minutes to set. Sprinkle the top with 0.25 cup chopped fresh parsley just before serving for a bright, fresh contrast.

Cut into 6 equal servings and serve immediately with a side of steamed green vegetables or a crisp salad. The creamy mashed potato topping will be perfectly set, while the fish filling remains tender and flavorful beneath the golden pastry crust.

Pro Tips For Making Campbell'S Soup Fish Pie

  • Pre-Cook the Fish: I learned this the hard way—raw fish in a pie filling just doesn’t set right. Poach the fillets in simmering water for 4-5 minutes first, then flake them into the soup mixture. This keeps the texture tender and prevents the fish from turning rubbery when baked.
  • Whisk the Soups Cold: Mixing Campbell’s soups straight from the can into the hot butter-flour roux? Bad idea. Let the soups cool slightly first—just 10 minutes in the fridge—or the butter will seize up and make a grainy mess. Trust me, your pie won’t look like gluey paste.
  • Skip the Overmixing: The moment you add the flour-butter mix to the soups, stir just until combined. Overmixing turns the filling into glue, and your pie will be dense instead of light. A few lumps? Doesn’t matter—it bakes out smooth.
  • Bake Covered, Then Uncover: Start with foil draped over the pie for the first 20 minutes to help the filling set. Then remove it for the last 10 minutes—this crisps the top and prevents a soggy crust. (Yes, even if you’re impatient like me.)

Essential equipment for campbell's soup fish pie

Pastry Tools Kit

For the perfect golden crust, I recommend a rolling pin with a marble surface—like the OXO Good Grips—to prevent sticking and achieve even thickness. A sharp chef's knife (I use Victorinox 8-inch) is essential for trimming excess pastry cleanly.

Don’t skip a pastry brush—the Westbloc Silicone Brush distributes egg wash evenly without soaking the pastry.

Baking Essentials

A 9x13-inch baking dish with a 2-inch rim (like Pyrex) ensures even heat distribution and prevents overflow. For temperature precision, invest in an instant-read thermometer—I trust the ThermoWorks Thermapen ONE to monitor the pie’s internal temp (165°F).

A parchment-lined sheet pan underneath catches spills and makes cleanup effortless.

Mash Mastery Tools

Potatoes need the right tools: a mandoline slicer (like OXO Good Grips) for uniform cubes or a sharp peeler for Yukon Golds. For mashing, a potato ricer (I use OXO Stainless Steel) creates ultra-smooth texture without lumps.

A wooden spoon or potato masher works too, but the ricer elevates the finish.

Fish Prep Gear

Use a fish cutter (like Mercer Culinary) to portion fillets evenly, or a sharp boning knife if you’re trimming fresh fish. A microplane (I love Barbour) zests garlic finely for aromatic depth. For sautéing, a 12-inch stainless steel skillet (like All-Clad) distributes heat evenly and prevents sticking.

Optional Upgrades

Add cheese to the mashed potatoes? A cheese grater (like Microplane 4-in-1) shaves sharp cheddar quickly. For extra crispiness, a pizza stone (like Lodge) boosts browning. And for make-ahead meals, a vacuum sealer (like FoodSaver) preserves freshness for up to 3 months. 💫

Frequently asked questions

1

Can I use frozen fish for this Campbell’s Soup Fish Pie?

Frozen fish works perfectly—just thaw it overnight in the fridge before cutting into chunks. Avoid thawing at room temperature, as this can make the fish mushy. For best results, use high-quality frozen fillets like cod or haddock from brands like Trader Joe’s or Whole Foods.

2

What’s the best way to keep the pastry from getting soggy?

Prevent a soggy crust by brushing the puff pastry with a thin layer of beaten egg before baking, then cutting small steam vents. Bake on a parchment-lined sheet pan to avoid moisture buildup, and avoid overfilling the pie—leave at least a ½-inch gap between the filling and pastry edge.

3

Can I make this recipe ahead of time?

Yes! Assemble the pie (without baking) up to 24 hours ahead and refrigerate. Bake straight from the fridge, adding 5–10 extra minutes to the 35–40 minutes baking time. For make-ahead mashed potatoes, store them in an airtight container with plastic wrap pressed directly on the surface to prevent drying.

4

What’s the difference between shortcrust and puff pastry for this dish?

Puff pastry delivers a flaky, golden finish with more lift, while shortcrust offers a denser, rustic texture. For this recipe, puff pastry is ideal—it contrasts beautifully with the creamy filling. If using shortcrust, press it firmly into the dish edges to seal and brush with extra egg wash for crispiness.

5

How do I reheat leftovers without drying out the pie?

Reheat slices at 350°F for 10–15 minutes, covered with foil to trap moisture. For microwave reheating, cover with a damp paper towel and heat in 30-second bursts
