Ingredients for baked cod with ritz crackers
Crispy crackers, melty cheese, and tender cod—just 12 ingredients for restaurant magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Cod Fillets 🐟 | 2 whole | Skinless, 6 oz each fillet |
| Ritz Crackers 🍞 | 1 ½ cups | Crushed into fine crumbs |
| Shredded Mozzarella Cheese 🧀 | 1 cup | Low-moisture, freshly shredded |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Garlic Cloves 🧄 | 2 cloves | Minced, fresh preferred |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For drizzling |

The cod is your star, so look for fresh fillets at the seafood counter—ask for wild-caught if possible. Whole Foods or Trader Joe's usually have great options, or grab frozen cod from Costco if fresh isn't available. Thaw overnight in the fridge if using frozen. The Ritz crackers? Don't buy the pre-crushed kind—crush them yourself for that perfect texture. For the cheese, low-moisture mozzarella is key—it melts smoothly without making the cracker topping soggy. I always grab the Sargento brand at the store, but any block cheese you can shred yourself works best.
No Ritz crackers? Crushed saltines or buttery round crackers work in a pinch. Running low on mozzarella? Parmesan or Gruyère adds depth—just use half the amount since they're stronger flavors. Fresh dill wilting? Dried dill at one-third the amount saves the day. The butter is non-negotiable for that golden crust—don't use margarine. For extra crunch, the panko breadcrumbs are optional but worth the extra minute if you've got them. And if you're feeling fancy, swap the cod for halibut or mahi-mahi—same technique, different flavor show.
This dish reheats beautifully—just 10 minutes at 350°F to crisp up the crackers again. Store leftovers in an airtight container for up to 2 days, but honestly, it's best fresh. For meal prep, portion the toppings separately and assemble before baking to keep everything crispy. The lemon juice can be prepped ahead, but add the zest fresh before serving. And trust me, the lemon wedges on the side make the whole dish sing—squeeze one over each serving right before eating.

Step-by-step instructions for baked cod with Ritz crackers
Here's how to create a restaurant-worthy dish with crispy cracker topping and gooey cheese perfection.
Prepare the Cod for Perfect Texture
Preheat your oven to 400°F while you prepare the cod. Pat the 2 whole Cod Fillets completely dry with paper towels—this is crucial for crispy skin. Place each fillet on a parchment-lined baking sheet and drizzle evenly with 2 tablespoons Extra-Virgin Olive Oil. Rub the oil into the fish until fully coated, then sprinkle with 1 teaspoon Salt and ½ teaspoon Black Pepper.
Here's the thing—don't skip the oil. It creates a barrier that prevents the fish from drying out while allowing the cracker topping to crisp beautifully. I like to press the seasoning gently into the fillets so it adheres well during baking. For extra flavor, sprinkle ¼ cup Fresh Dill and 1 teaspoon Lemon Zest over each fillet before moving to the next step.
Create the Crispy Cracker Topping
In a food processor, pulse the 1.5 cups Ritz Crackers until you achieve fine, sand-like crumbs—think breadcrumbs but with that buttery Ritz flavor. Transfer these to a medium bowl and mix in ¼ cup Panko Breadcrumbs (if using) for extra crunch. Add ½ cup Unsalted Butter, melted and slightly cooled, and stir until evenly distributed.
This is where the magic happens. The melted butter binds the cracker crumbs together while adding richness that complements the delicate cod. For extra flavor, add 2 tablespoons Lemon Juice and 2 minced Garlic Cloves to the mixture. Stir well—you want every crumb coated in that buttery, zesty goodness. If the mixture seems too dry, add just enough water (about 1 teaspoon) to hold together when pressed.
Assemble and Bake to Golden Perfection
Spoon the cracker mixture evenly over each cod fillet, pressing down gently to create an even layer. Then, sprinkle 1 cup Shredded Mozzarella Cheese evenly over the cracker topping. Here's the moment that matters: the cheese will melt into a gooey blanket while the cracker topping crisps to perfection.
Bake for 12-15 minutes until the cracker topping is deep golden brown and the cheese has turned bubbly and slightly browned on top. The cod should be opaque and flake easily when tested with a fork. Real talk: don't overbake—cod cooks quickly and can dry out if left in too long. If your oven runs hot, start checking at the 10-minute mark.
Rest and Serve with Zesty Freshness
Remove the baking sheet from the oven and let the cod rest for 3-5 minutes before serving. This resting time allows the juices to redistribute, ensuring each bite stays moist and flavorful. While it rests, give the top a final sprinkle of ¼ cup Fresh Dill and an extra pinch of ½ teaspoon Black Pepper for that fresh, vibrant finish.
Serve immediately with lemon wedges on the side—squeezing fresh lemon juice over each portion brightens the flavors and cuts through the richness of the cracker topping. The contrast of crispy, cheesy crunch with tender, flaky cod is what makes this dish truly special. Trust me, your guests will be asking for seconds!
Pro Tips For Making Baked Cod With Ritz Crackers
- Preheat Like It’s Hot: Your oven should hit 425°F (220°C) and stay there for at least 15 minutes before baking—no exceptions. I used to slide the dish in cold and wonder why the crackers stayed bland and the cheese didn’t melt properly. That extra heat is what turns this into a crispy, gooey masterpiece, not just a sad casserole.
- Crush Crackers Small: Skip the big chunks—pulse Ritz crackers in a food processor or smash them with a rolling pin until they’re fine crumbs. Large pieces turn into soggy islands while the rest gets golden. My first attempt looked like a cracker buffet, but this method guarantees even, crispy coverage every time.
- Butter the Cod Last: Add the unsalted butter and lemon juice to the cod right before baking—not when you’re prepping. The acid in the lemon will make the butter sizzle and flavor the fish instantly, but if you mix it too early, the butter oxidizes and tastes stale. Fresh = better. Always.
- Press Cheese Down Hard: Don’t just sprinkle the mozzarella—pack it firmly into the cracker-crusted cod with your fingers or a spatula. This locks in moisture and prevents the cheese from sliding off mid-bake. I learned this after watching my first batch turn into a cheesy avalanche. Now it stays put.
Best sauces and condiments for this recipe
Creamy Garlic Sauce
Drizzle your baked cod with a homemade garlic aioli to elevate the dish instantly. Mix ½ cup mayonnaise (I love Duke's for its rich flavor), 1 tbsp lemon juice, 1 minced garlic clove, and a pinch of salt.
Spread a thin layer over the cracker topping before baking, or serve it on the side for dipping. The tangy garlic balances the richness of the cheese and crackers perfectly. 🌶️
Lemon-Herb Butter
Create a zesty lemon-herb butter by combining 4 tbsp softened unsalted butter, 1 tbsp lemon zest, 1 tbsp chopped fresh dill, ½ tsp salt, and a pinch of black pepper. Dollop small spoonfuls onto each plate and let guests spread it over their cod.
This adds a bright, herby contrast to the salty crackers and melty cheese. I always make extra—it’s perfect for toast or grilled fish too!
Spicy Remoulade
For a bold kick, whip up a Cajun-inspired remoulade by blending ½ cup mayonnaise, 1 tbsp Dijon mustard, 1 tbsp hot sauce (like Crystal or Tabasco), 1 tsp Worcestershire sauce, 1 minced garlic clove, and ½ tsp smoked paprika.
Drizzle over the baked cod or serve alongside for dipping. The heat cuts through the richness, making every bite exciting. 🔥
White Wine Sauce
A light white wine sauce adds sophistication without overpowering the cod. Sauté 2 minced garlic cloves in 1 tbsp olive oil until fragrant, then deglaze with ¼ cup dry white wine (like Sauvignon Blanc).
Simmer until reduced by half, then stir in 2 tbsp heavy cream and a splash of lemon juice. Pour over the baked cod just before serving—it’s elegant and pairs beautifully with the cracker topping.
Tartar Sauce Twist
Give classic tartar sauce a seafood upgrade by mixing ½ cup mayonnaise, 1 tbsp capers, 1 tbsp chopped fresh parsley, 1 tsp lemon juice, and ½ tsp Old Bay seasoning.
The briny capers and Old Bay complement the cod’s natural sweetness while adding a salty crunch that mirrors the Ritz crackers. Serve as a side or dollop directly onto the baked fish for extra flavor. 🍤
Honey-Mustard Glaze
For a sweet-and-tangy contrast, brush the baked cod with a honey-mustard glaze made from 2 tbsp Dijon mustard, 1 tbsp honey, and 1 tsp lemon juice.
Thin with a splash of water if needed, then drizzle over the cracker topping in the last 2 minutes of baking. The caramelized glaze adds a sticky, glossy finish that’s irresistible. Perfect for balancing the salty crackers and rich cheese. 🍯

Frequently asked questions
Can I use frozen cod for this recipe?
Yes, but thaw it properly first! Place frozen cod in the fridge overnight (about 12-24 hours) for even thawing. Never thaw at room temperature—this can make the fish unsafe to eat. Once thawed, pat it completely dry before seasoning to ensure that crispy cracker topping sticks perfectly.
What if I don't have Ritz crackers?
No problem! Use crushed saltine crackers or buttery round crackers for a similar texture. For extra flavor, add 1 teaspoon garlic powder or ½ teaspoon smoked paprika to the cracker mixture. The key is fine, even crumbs that will crisp up nicely during baking.
Why did my cracker topping get soggy?
Soggy topping usually means one of two things: either the cod wasn't dry enough before baking, or the cracker mixture had too much moisture. Always pat the fish completely dry with paper towels, and if your cracker mixture feels too wet, add 1-2 tablespoons more crushed crackers to absorb excess liquid. Bake at the recommended 400°F for optimal crispiness.
Can I make this ahead of time?
Assemble the cod with toppings, but skip the cheese until ready to bake. Store in an airtight container in the fridge for up to 24 hours. When ready to bake, add the cheese and cook as directed. For a make-ahead dinner, this saves time without sacrificing texture. The cheese will still melt beautifully when baked fresh.
What's the best way to reheat leftovers?
Reheat leftovers in a 375°F oven for 8-10 minutes to restore crispiness. Place the cod on a baking sheet and cover loosely with foil to prevent over-browning. For extra crunch, sprinkle a few extra crushed crackers on top before reheating. Microwaving will make the topping soggy, so always use the oven method.
