Crab Fettuccine Alfredo is an incredibly delicious dinner that comes together in a snap! Fettuccine topped with creamy homemade Alfredo sauce filled with lump crab–a really special meal that can easily be made any night of the week.
Crab Fettuccine Alfredo
This meal was so super easy to make and pretty much start-to-finish done in less than 30 minutes. We all loved it so much, this is for sure going into the regular dinner rotation.
One thing I really liked about this recipe is that we used milk instead of heavy cream to make the Alfredo sauce. I love a good Alfredo made with butter, heavy cream, and Parmesan, but it’s so heavy and incredibly high fat. Making the sauce with milk didn’t impact the flavor (the addition of cream cheese makes it nice and creamy) but really reduced the fat content.
Here’s what you’ll need to make the Crab Fettuccine Alfredo (the exact measurements and full recipe instructions are below in the printable recipe card):
- All-purpose flour
- Fresh Parmesan cheese – don’t use the grated Parmesan from a jar–buy a wedge of real Parmesan and finely grate it at home. It just takes a minute to do and makes a big difference in the sauce.
- Cream cheese
- Garlic powder
- Onion powder
- Fresh parsley
- Imitation lump crab
How to Make Crab Fettuccine Alfredo
Cook the pasta first and set it aside. Next, melt the butter in a large skillet over medium heat. Add the flour and whisk together. Cook this mixture, called a roux (pronounced “roo“), for 30-60 seconds. Add the milk to the roux very slowly, whisking well between additions. It will be very thick and lumpy at first, but as you continue to add the milk you’ll see a nice sauce come together.
Add the cream cheese and allow it to melt into the sauce, then add the grated parmesan cheese, fresh parsley, onion powder, garlic powder, salt, and pepper.
Whisk the sauce together until smooth and creamy.
Add the crabmeat to the sauce and allow it to cook just until hot.
You can either spoon the sauce over the pasta on plates, or add it right to the pan and toss with the sauce.
You may also want to add a sprinkle of fresh parsley to the top for extra color.
Crabmeat – I used imitation crab for this recipe and it was delicious. But you can use any type of fully cooked crabmeat that you like.
Nutmeg – Try adding a small pinch of ground nutmeg to the sauce for a little extra flavor.
Heavy cream – Although this sauce is nice and creamy already, if you would like it to be a little richer you can add a splash of heavy whipping cream before adding the crabmeat.
Different pasta – We loved the fettuccini, but this dish is also wonderful with linguini, spaghetti, angel hair, or penne.
How to Store Leftovers
Keep any leftovers in a container with a lid in the refrigerator. The leftovers are best eaten within a day or two. Reheat in the microwave and top with extra Parmesan cheese if you like.
