Ingredients
This recipe makes 6 generous servings.
For the Casserole
- 1.5 lbs (about 680g) cod fillets, fresh or frozen (thawed), skinless and boneless
- 2 lbs (about 900g) Yukon Gold or Russet potatoes, peeled and cut into 1/2-inch cubes
- 4 tablespoons unsalted butter, divided
- 1 medium yellow onion, finely chopped
- 2 cloves garlic, minced
- 4 tablespoons all-purpose flour
- 3 cups whole milk
- 1 teaspoon dried dill (or 1 tablespoon fresh, chopped)
- 1/2 teaspoon salt, plus more to taste
- 1/4 teaspoon black pepper, plus more to taste
- 1.5 cups shredded cheese (Cheddar, Gruyère, or a mix)
- 1/2 cup Panko breadcrumbs (optional, for extra crunch)
- Fresh parsley, chopped, for garnish (optional)
Step-by-Step Instructions
-
Step 1: Prepare the Potatoes
Place the cubed potatoes in a large pot and cover with cold water. Add a pinch of salt. Bring to a boil over medium-high heat, then reduce heat and simmer for 10-12 minutes, or until the potatoes are tender when pierced with a fork but not mushy. Drain well and set aside.
Small tip: Don’t overcook the potatoes, as they will continue to cook in the oven.
-
Step 2: Sauté Aromatics
While the potatoes are cooking, preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish. In a large saucepan or Dutch oven, melt 2 tablespoons of butter over medium heat. Add the chopped onion and cook for 5-7 minutes until softened and translucent. Stir in the minced garlic and cook for another minute until fragrant.
-
Step 3: Make the Creamy Sauce
Sprinkle the flour over the softened onions and garlic. Cook, stirring constantly, for 1-2 minutes to create a roux. Gradually whisk in the milk, a little at a time, ensuring no lumps form. Continue to whisk until the sauce thickens, about 5-7 minutes. It should be smooth and creamy.
Small tip: Keep whisking to prevent the sauce from sticking to the bottom of the pan.
-
Step 4: Season the Sauce
Remove the sauce from the heat. Stir in the dried dill, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Taste and adjust seasonings as needed. The sauce should be well-seasoned, as it will flavor the cod and potatoes.
-
Step 5: Assemble the Casserole
Cut the cod fillets into 1-inch pieces. Gently fold the drained, cooked potatoes and the cod pieces into the creamy sauce until everything is evenly coated. Pour the mixture into your prepared 9×13 inch baking dish, spreading it out evenly.
-
Step 6: Add the Topping
Sprinkle the shredded cheese evenly over the top of the casserole. If using, melt the remaining 2 tablespoons of butter and toss with the Panko breadcrumbs. Sprinkle the buttered breadcrumbs over the cheese for a crispy topping.
Small tip: The breadcrumbs add a wonderful texture, but the casserole is delicious even without them.
-
Step 7: Bake to Perfection
Bake in the preheated oven for 30-35 minutes, or until the casserole is bubbling around the edges and the topping is golden brown and crispy. The cod should be cooked through and flake easily. Let it rest for 5-10 minutes before serving.
-
Step 8: Garnish and Serve
Garnish with fresh chopped parsley, if desired. Serve hot and enjoy the comforting flavors of this delicious Cod and Potato Casserole!
Tips & Variations
- Gluten-Free Option: Easily make this recipe gluten-free by swapping the all-purpose flour for a gluten-free all-purpose flour blend (ensure it contains xanthan gum) when making the roux. Also, use gluten-free breadcrumbs or omit them entirely.
- Vegetarian Option: For a delicious vegetarian casserole, simply omit the cod. You can add extra vegetables like peas, corn, or chopped bell peppers for more substance and flavor. Consider adding a can of drained chickpeas for protein.
- Add More Vegetables or Protein: Feel free to boost the veggie content! Stir in a cup of frozen peas, corn, or chopped spinach (squeezed dry) along with the potatoes and cod. For extra protein, cooked shrimp or scallops would also be lovely additions.
- Spicy Version: If you love a little heat, add a pinch of red pepper flakes to the sauce along with the salt and pepper. A dash of hot sauce stirred into the finished sauce before baking also works wonderfully.
- Cheesy Topping Variations: Experiment with different cheeses! A blend of Parmesan and mozzarella creates a lovely crust. For a sharper flavor, use a mature cheddar. You could even mix in a little cream cheese into the sauce for extra richness.
