Crab Casserole Ingredients For the Casserole Mayonnaise – Adds creaminess and moisture; substitute with Greek yogurt for a lighter option. Sour Cream – Provides tanginess and richness; can replace with additional mayonnaise or cream cheese. Lemon Zest – Enhances flavor with a fresh citrus note; use lime zest or omit if undesired. Cheddar Cheese – Offers classic cheesy flavor and melty texture; substitute with Colby, pepper jack, or mozzarella. Green Onions – Adds mild onion flavor and color; chives or diced parsley can be used instead. Celery (optional) – Adds crunch and freshness; omit if unwanted or replace with bell peppers. Imitation Crab Meat – The main protein that gives the dish its seafood essence; real crab meat or chopped crab sticks can be used. Step‑by‑Step Instructions for Easy Cheesy Crab Casserole Step 1: Preheat and Prepare Baking Dish Begin by preheating your oven to 375°F (190°C). While it heats, take an 8×8 baking dish and generously grease it with cooking spray or butter. This will ensure your Easy Cheesy Crab Casserole slides out effortlessly once baked. Set the dish aside as you prepare the other ingredients. Step 2: Prepare the Crab Meat If using imitation crab sticks, chop them into small, bite-sized pieces. If you have chunk or flake crab meat, gently break half of it into smaller bits for better distribution. This ensures a delightful bite of crab in your casserole. Set the prepared crab meat aside to be mixed in with the other ingredients. Step 3: Mix the Ingredients In a large mixing bowl, combine the chopped crab meat, mayonnaise, sour cream, lemon zest, diced green onions, and celery if you’re using it. Stir in ¾ cup of shredded cheddar cheese, mixing until everything is well-coated and the ingredients are evenly distributed. The creamy texture will be enticing as you blend it all together. Step 4: Transfer Mixture and Add Topping Carefully spoon the crab mixture into your greased baking dish, spreading it out evenly with a spatula. This ensures that your Easy Cheesy Crab Casserole bakes uniformly. Once level, sprinkle the reserved cheddar cheese and any remaining green onions over the top for a beautiful finish that will melt into a golden crust. Step 5: Bake to Perfection Place the baking dish in the preheated oven and bake for 25 to 30 minutes. Keep an eye on it; you want the casserole to be warmed through and the cheese on top to turn a lovely golden brown. For an extra touch, broil for 1-2 minutes at the end to achieve a bubbly, crispy top. Step 6: Serve and Savor Once your Easy Cheesy Crab Casserole is out of the oven, let it sit for a few minutes to cool slightly. This will make serving easier and allow the flavors to meld beautifully. Cut into squares, serve hot, and watch it become a favorite among your family and friends as they dive into the comforting richness! How to Store and Freeze Crab Casserole Fridge: Store leftover Crab Casserole in an airtight container for up to 3 days. This keeps it fresh and ready for a quick reheat later! Freezer: For longer storage, freeze the casserole before baking it. Wrap it tightly in plastic wrap followed by aluminum foil, and it will keep for up to 2 months. Reheating: When ready to enjoy, thaw overnight in the fridge. Reheat in the microwave for 30-45 seconds or bake at 350°F (175°C) until heated through, about 20-25 minutes. Covering: Always cover the dish while reheating to retain moisture and prevent the top from browning too quickly.

You can prepare the entire crab mixture up to 24 hours in advance by combining the crab meat, mayonnaise, sour cream, lemon zest, green onions, and cheese in a large mixing bowl.

When you’re ready to serve, simply transfer the mixture to your greased baking dish, sprinkle with the reserved cheese, and bake at 375°F (190°C) for 25 to 30 minutes. This not only allows the flavors to meld beautifully but ensures you enjoy restaurant-quality results with minimal effort on busy weeknights! What to Serve with Easy Cheesy Crab Casserole?

Expert Tips for Delicious Crab Casserole Taste as You Go: Always taste the crab mixture before baking. Since it contains no raw eggs, you can adjust the seasoning freely, ensuring a perfect blend of flavors. Enhance the Flavor: For a deeper taste, consider adding ingredients like garlic powder, Worcestershire sauce, or a splash of hot sauce to your crab casserole. Cheese Smartly: Avoid using heavy cream cheese unless it’s desired; if you do, start with just a couple tablespoons mixed with mayonnaise for better texture integration. Adapting Ingredients: Don’t hesitate to customize the ingredients with what you have on hand. For instance, Greek yogurt can replace mayonnaise for a lighter crab casserole. Watch the Bake Time: Keep an eye on the casserole while baking. Broiling for a minute at the end can give you that irresistible golden crust without overcooking it.

Crab Casserole Recipe FAQs How do I choose ripe crab meat? Absolutely!

If your casserole is too watery, you might need to adjust the moisture content. Be sure to drain any liquid from your crab meat if it’s packed in water.
