Ingredients You’ll Need for Crab and Shrimp Casserole
Here’s everything you need to make this seafood masterpiece.
- 1 cup lump crab meat
- 1 cup cooked shrimp (peeled and chopped)
- 1 cup shredded cheddar cheese
- ½ cup mozzarella cheese
- ½ cup mayonnaise
- ½ cup sour cream
- ½ cup crushed buttery crackers (like Ritz)
- 2 tablespoons melted butter
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon paprika
- ½ teaspoon black pepper
- 1 tablespoon lemon juice
- 2 tablespoons chopped parsley
- Optional: ½ cup cooked rice or pasta for extra bulk
Pro tip: Always check crab meat for shell pieces. Crunchy crab shells are not the vibe.
Step-by-Step Instructions
1. Preheat the oven
Preheat your oven to 375°F (190°C). Don’t skip this step. Cold ovens equal sad casseroles.
Grease a medium casserole dish lightly with butter or cooking spray.
2. Mix the creamy base
Grab a large bowl and combine:
- mayonnaise
- sour cream
- garlic powder
- onion powder
- paprika
- black pepper
- lemon juice
Stir everything until smooth and creamy.
3. Add the seafood and cheese
Fold in the crab meat, shrimp, cheddar cheese, and mozzarella.
Mix gently so the seafood stays chunky. Nobody wants shredded seafood mush.
4. Transfer to the baking dish
Spread the mixture evenly in your prepared casserole dish.
Smooth the top with a spatula like the professional chef you definitely are now.
5. Make the crispy topping
In a small bowl, mix:
- crushed crackers
- melted butter
- chopped parsley
Sprinkle this buttery mixture evenly over the casserole.
This topping = crispy heaven.
6. Bake to golden perfection
Bake uncovered for 25–30 minutes.
You’ll know it’s ready when the top turns golden and the edges start bubbling like a tiny seafood volcano.
7. Let it rest (yes, really)
Let the casserole rest for 5–10 minutes before serving.
This helps everything set properly. Plus it prevents you from burning your mouth like an impatient raccoon.
Common Mistakes to Avoid
Let’s save you from the most common casserole disasters.
Skipping the preheated oven
Thinking the oven will “warm up eventually”? Rookie mistake.
Overmixing the seafood
Crab and shrimp should stay chunky. Overmixing turns it into seafood paste.
Using too much salt
Crab and cheese already bring plenty of saltiness.
Not draining shrimp properly
Extra water = soggy casserole. Nobody asked for seafood soup.
Overbaking it
Thirty minutes is usually enough. Dry seafood is a tragedy.
Alternatives & Substitutions
No ingredient? No problem.
No crab meat?
Use extra shrimp or even imitation crab.
Want it lighter?
Swap mayo for Greek yogurt. IMO it still tastes great.
Need more carbs?
Add cooked rice, pasta, or even diced potatoes.
Different cheese?
Try Monterey Jack, Gruyère, or Parmesan.
Spice lover?
Add a dash of hot sauce or cayenne pepper.
Honestly, casseroles are forgiving. You can tweak them without culinary chaos.
FAQs about Crab and Shrimp Casserole
Can I use frozen shrimp?
Absolutely. Just thaw and pat them dry first. Extra moisture is the enemy of good casseroles.
Can I make this casserole ahead of time?
Yep! Assemble everything and store it in the fridge for up to 24 hours before baking.
Just add 5–10 minutes to the baking time.
Can I freeze crab and shrimp casserole?
You can, but seafood sometimes changes texture after freezing.
If you do freeze it, wrap it tightly and use it within 2 months.
What side dishes go well with this?
Great question.
Some easy options:
- Garlic bread
- Simple green salad
- Roasted vegetables
- Steamed rice
Basically anything that helps scoop up that creamy goodness.
Can I make it without mayonnaise?
Sure. Replace it with cream cheese or Greek yogurt.
The texture will change slightly, but it’ll still taste great.
How do I know when the casserole is done?
Look for bubbly edges and a golden crispy topping.
If it smells amazing and you’re hovering around the oven like a food detective, it’s probably ready.
