How to Make Creamy Crab Mac and Cheese 🦀🧀
- First, cook the elbow macaroni according to package instructions until al dente. Drain and set aside.
- In a large saucepan, melt the butter over medium heat. Stir in the flour and cook for about 1 minute, stirring constantly.
- Gradually whisk in the milk, ensuring there are no lumps. Continue to cook until the mixture thickens, about 5-7 minutes.
- Stir in the Dijon mustard, garlic powder, onion powder, cayenne pepper, salt, and pepper.
- Remove the saucepan from heat and add the shredded cheddar cheese, stirring until melted and smooth.
- Gently fold in the cooked macaroni and lump crab meat until well combined.
- If desired, transfer the mixture to a baking dish and top with breadcrumbs. Bake in a preheated oven at 350°F (175°C) for 20 minutes or until golden and bubbly.
- Garnish with chopped fresh parsley before serving.
Substitutions & Additions
If you want to switch things up a bit, here are some ideas:
- Try different types of cheese like Gruyere or Monterey Jack for a unique flavor.
- Add some sautéed spinach or broccoli for a veggie boost.
- Substitute crab meat with shrimp or lobster for a seafood twist.
- For a smoky flavor, consider adding a bit of smoked paprika.
Tips for Success
- Make sure to stir the flour and butter well to avoid lumps in your cheese sauce.

- If you are preparing this ahead of time, you can assemble it without baking and refrigerate. Just add a few extra minutes to the baking time.
