Step-by-Step: Shrimp Casserole Recipe

Step 1: Prepare the Shrimp
Start by bringing a large pot of salted water (with 1 Tbsp salt and Old Bay seasoning) to a boil. Once boiling, add the shrimp and cook for about 2-3 minutes, or until they turn pink and opaque. Drain and set aside.
Step 2: Mix the Sauce
In a mixing bowl, combine the mayonnaise, garlic powder, and ground black pepper. Stir well until the mixture is smooth and evenly blended.
Step 3: Combine Ingredients
Add the cooked shrimp to the mayonnaise mixture. Gently fold the shrimp into the sauce until they are well coated.
Step 4: Prepare the Baking Dish
Preheat your oven to 350°F (175°C). Grease a 2-quart baking dish with butter to ensure the casserole doesn’t stick.
Step 5: Assemble the Casserole
Pour the shrimp mixture into the prepared baking dish. Spread it out evenly, then sprinkle the shredded mozzarella and cheddar cheese on top.
Step 6: Add the Crunchy Topping
In a small bowl, mix the panko bread crumbs with a little melted butter (about 1 Tbsp) to help them brown nicely. Sprinkle this mixture evenly over the cheese layer.
Step 7: Bake the Casserole
Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and the top is golden brown.
Step 8: Serve and Enjoy
Once baked, remove the casserole from the oven and let it cool for a few minutes before serving. This Shrimp Casserole Recipe is delicious on its own or served with a side salad or crusty bread.
Vegan & Vegetarian Swaps

- Replace shrimp with cooked chickpeas or tofu for a vegetarian option.
- Use a vegan mayonnaise alternative to make the casserole plant-based.
- Consider using nutritional yeast in place of cheese for a cheesy flavor without dairy.
- Switch the butter for a vegan butter substitute.
Troubles You Can Avoid
To make sure your Shrimp Casserole Recipe comes out perfectly, here are a few tips:
- Be careful not to overcook the shrimp when boiling; they should be just cooked through.
- Ensure that the baking dish is greased well to avoid sticking.
- Feel free to adjust the seasoning to your liking; taste the mixture before baking.
- Let the casserole rest for a few minutes after baking to allow it to set before serving.
Shelf Life & Storage
If you have leftovers (which is a rarity!), store them in an airtight container in the refrigerator for up to 3 days. To reheat, simply place in the oven at 350°F (175°C) until warmed through. For longer storage, you can freeze the casserole before baking it. Just cover it tightly with plastic wrap and aluminum foil. It can be frozen for up to 2 months; thaw in the fridge overnight before baking as usual.
