Step‑by‑Step Instructions for Crab Casserole Recipe
Step 1: Preheat and Prepare Baking Dish
Begin by preheating your oven to 350°F (175°C). While the oven heats, lightly grease a 9×9-inch baking dish with cooking spray or butter. This will ensure that your creamy crab casserole doesn’t stick and allows for easy serving once it’s baked to golden perfection.
Step 2: Sauté the Vegetables
In a skillet over medium heat, add a drizzle of olive oil and sauté the chopped onion, celery, and bell pepper until they soften, about 5–7 minutes. Stir occasionally to prevent burning. Once they’re tender and fragrant, remove them from the heat and set aside to cool while you prepare the crab mixture.
Step 3: Mix the Creamy Base
In a large mixing bowl, whisk together the mayonnaise, sour cream, Dijon mustard, Worcestershire sauce, lemon juice, and egg until the mixture is smooth and well combined. Add garlic powder, paprika, salt, and pepper to taste, making sure to adjust the seasoning to your preference. This creamy base will provide the backbone of your crab casserole recipe.
Step 4: Combine the Ingredients
Gently fold in the lump crab meat and the sautéed vegetables into the creamy mixture. Be careful not to overmix, as you want to preserve the chunks of crab for texture. Ensure everything is evenly coated with the creamy goodness, enhancing the flavor and heartiness of your casserole.
Step 5: Transfer and Top
Carefully transfer the crab mixture into the prepared baking dish, spreading it out evenly. Then, sprinkle a generous layer of shredded cheese on top, followed by a layer of breadcrumbs. The cheese will melt beautifully, while the breadcrumbs will give your crab casserole a deliciously crunchy topping.
Step 6: Bake to Perfection
Place the baking dish in the preheated oven and bake for 25–30 minutes. You’ll know it’s done when the top is golden brown and bubbly around the edges. This step creates a beautiful crust while ensuring the inside remains creamy and flavorful, embodying the essence of a warming crab casserole.
Step 7: Cool and Serve
Once your crab casserole is out of the oven, allow it to cool for about 5–10 minutes. This brief cooling period helps the casserole set, making it easier to serve. The end result will be a creamy, comforting dish that’s ready to be enjoyed with friends and family!

Crab Casserole Recipe FAQs
How do I select the best crab meat for this recipe?
Absolutely! When choosing crab meat, look for lump crab meat as it offers the best flavor and texture. Fresh crab is ideal, but if that’s unavailable, canned or imitation crab can be convenient substitutes. Just ensure the canned version is packed in water or brine, not oil, to maintain its taste.
How should I store leftover crab casserole?
Very simple! Place any leftover crab casserole in an airtight container and refrigerate for up to 3 days. Just make sure it’s completely cooled before sealing it to prevent moisture buildup, which can affect texture and flavor.
Can I freeze crab casserole for future meals?
Yes, you can! To freeze an unbaked crab casserole, wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It can last for up to 2 months in the freezer. When you’re ready to bake, thaw it overnight in the fridge before popping it into the oven.
What should I do if my casserole comes out too watery?
If your crab casserole turns out watery, it could be due to excess liquid from ingredients like crab or vegetables. To remedy this, you can bake it a bit longer to evaporate some of the moisture. Alternatively, reduce the amount of sour cream or mayonnaise next time, or let vegetables sweat out their moisture before combining.
Are there any dietary considerations for this crab casserole?
Absolutely! This crab casserole can easily be tailored to accommodate gluten-free diets by using gluten-free breadcrumbs. Additionally, if anyone in your group has seafood allergies, consider substituting the crab with a cooked chicken or a medley of veggies for a delicious alternative. Always check all ingredients to ensure they align with dietary needs!
