Preheat your grill to medium high heat. Brush the cod fillets with olive oil and season with smoked paprika, garlic powder, salt, and pepper.
Grill the cod fillets for 3 5 minutes per side, or until cooked through and flaky. Be careful not to overcook the fish. Remove from the grill and set aside to cool slightly. Once cool enough to handle, flake the cod into bite size pieces.
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
In a large bowl, combine the thinly sliced potatoes, sliced onion, minced garlic, heavy cream, milk, salt, and pepper. Mix well to ensure the potatoes are evenly coated.
Pour half of the potato mixture into the prepared baking dish. Spread it out evenly.
Sprinkle one cup of shredded cheddar cheese over the potato mixture.
Distribute the flaked grilled cod evenly over the cheese layer.

Pour the remaining potato mixture over the grilled cod.
Bake for 45 50 minutes, or until the potatoes are tender and the casserole is bubbly.
Sprinkle the remaining one cup of shredded cheddar cheese over the casserole. Bake for another 5 10 minutes, or until the cheese is melted and golden brown. Let it sit for about 10 minutes before serving. Serve hot and enjoy! If you are looking for an elegant appetizer, you might also enjoy this Hamachi Crudo.
How to Serve This grilled cod casserole Recipe
This grilled cod casserole is a complete meal on its own, but there are many ways to enhance your dining experience.
Serve it with a simple green salad for some freshness and a vibrant color contrast. A side of steamed green beans or asparagus would also complement the richness of the casserole perfectly.
For a more casual meal, top the casserole with a dollop of sour cream or Greek yogurt and a sprinkle of fresh chives. A squeeze of lemon juice brightens the flavors significantly. Consider adding a sprinkle of red pepper flakes for a touch of heat.
How to Store This grilled cod casserole Recipe
Proper storage is key to enjoying leftovers of this delicious grilled cod casserole.
To refrigerate, allow the casserole to cool completely before covering it tightly with plastic wrap or transferring it to an airtight container. It can be stored in the refrigerator for up to 3 4 days.
For longer storage, the casserole can be frozen. Cut it into individual portions for easier thawing and reheating. Wrap each portion tightly in plastic wrap and then in aluminum foil, or place them in freezer safe containers. Frozen casserole can last for up to 2 3 months.

Tips to Make This grilled cod casserole Recipe
Here are a few helpful tips to ensure your grilled cod casserole turns out perfectly every time.
If you don’t have Yukon Gold potatoes, russet potatoes work well too. Just be sure to slice them thinly. For a creamier casserole, use half and half instead of milk. For extra flavor, try adding a bay leaf to the potato mixture while it bakes.
Avoid overcooking the cod during grilling, as it will continue to cook in the casserole. If you don't have a grill, you can pan sear the cod in a skillet with olive oil. Using pre shredded cheese can save time, but freshly grated cheese melts more smoothly. Watch the casserole closely during the last few minutes of baking to prevent the cheese from burning.
Helpful Notes for This grilled cod casserole Recipe
A few extra details can make all the difference in this grilled cod casserole.
Smoked paprika is key to achieving that smoky flavor, so don’t skip it! If you prefer a different cheese, Monterey Jack, Gruyere, or a combination of cheddar and Parmesan also work beautifully.
The baking dish you use can impact the cooking time. Glass dishes tend to cook more evenly, while metal dishes may require a slightly shorter baking time. Make sure the potatoes are sliced thinly and evenly for uniform cooking. If you want to add a bit of elegance to your blog post, consider adding the following:
