Macaroni & Cheese with Halibut

Sharing is caring!

Once we have our supply of Alaskan whitefish for the year (thanks to my husband’s fishing trip), I’m ready to prepare delicious meals for our family. Macaroni & cheese with halibut is one of our favorites.

Our family loves homemade macaroni & cheese and have been enjoying the same recipe for years and years. Once we moved to Alaska, my husband started going fishing and filling our freezer with whitefish including lingcod, rockfish, and of course, halibut. It only made sense to add some to our favorite pasta dish!

I most often make this dish using leftover fish from a previous meal. I purposely prepare extra to have on hand for this recipe. Usually, one fillet isn’t enough for our family of six but two fillets is a bit too much. This is perfect because I don’t need a lot to mix in with this recipe and I have another delicious meal that our family loves.

I have even made this using leftover beer-battered fried halibut that we sometimes make for a special treat, especially for out-of-town guests who are looking forward to a classic Alaskan meal. This recipe will work with any whitefish that you have.

If you don’t have any leftovers to use, cooking a fresh fillet just for this recipe is also an option that I have done many times. Simply bake your fish (drizzled with a little olive oil and lightly seasoned with salt and pepper) in a 400 degree F oven for about 10-15 minutes, depending on thickness, until the internal temperature reaches 140 degrees F. If you are using leftover fish, there is no need to reheat prior to using in this recipe.

What to Serve with Seafood Macaroni and Cheese

This dish makes a complete, filling meal on its own but is even better with a salad or other vegetable dish served on the side. I like to whip up a quick salad using whatever greens we have on hand, sprinkling in some lightly toasted nuts (pine nuts and pecans are our favorites), and drizzling some olive oil and balsamic vinegar on top.

How to Reheat

As with many pasta dishes, this recipe reheats so well and is delicious leftover. I always choose to reheat it in the oven set to 350 degrees F. It only takes about 10-15 minutes to warm it back up and serve as a tasty lunch over the next day or two, if there’s any left at all! My husband has taken this leftover to work many times and reheated it in the microwave successfully as well.

This is a tried-and-true favorite in our family that we have been enjoying for years, even prior to adding the fish in. This dish is also great to take to potlucks or family dinners and easily doubles for more portions. Plus, most children love mac n’ cheese so adding a healthy ingredient such as fish makes it better for them.

Alaskan white fish is so delicious and versatile. I hope you and your family enjoy this meal, a taste of Alaska!
