Ingredient Notes:

For the full list of ingredients and amounts, please go to the recipe card below.

  • Cod – Use fresh or previously frozen and thawed cod. I love using cod because it is a mild, kid-friendly fish. You can use any fish or shellfish in this recipe, so choose what you like.
  • Heavy Cream – This is a staple of alfredo sauces. Please don’t use half and half.
  • Parmesan Cheese
  • Garlic – Use fresh or jarred minced garlic. In a pinch, you can use garlic powder.
  • Gluten Free Pasta – I used Jovial Taggeline because it is like fettuccine noodles, but you can use any gluten free pasta shape.
  • Butter – Use salted or unsalted butter. If you use salted butter, omit additional salt.
  • Basil – Fresh basil is best, but dried works as well.

Step-By-Step Photos and Directions:

If your cod was previously frozen, thaw it and pat it dry with paper towels. Set a pot of water to boil the gluten-free pasta.

Step 1: Saute the cod with olive oil and fresh basil in a skillet over medium heat. Cod cooks pretty quickly, so you would only need to sauté for about 7-10 minutes, depending on how thick the fish is.

Step 2: Heat the heavy cream, butter, salt, and pepper in a large skillet over medium-low heat. When bubbles form, turn the heat down to low to simmer.

Step 3: Once the cod is cooked, drain the cooking juices and chop it into large pieces. When shredding the fish, double-check for bones.

Step 4: Cook your pasta according to package directions. Every brand has different cooking times, so do read the box cooking suggestions. I share a lot more tips to get al dente gluten free pasta.

If you like these thick pasta noodles, use Jovial brown rice tagliatelle. Add the cooked pasta and cod to the creamy alfredo sauce.

Frequently Asked Questions:

Can you make alfredo dairy-free?

It is possible to make this recipe dairy-free now that So Delicious makes a dairy-free heavy cream. If you want to try using non-dairy milk, vegan butter, and dairy-free parmesan cheese (VioLife makes a great vegan parmesan cheese), try it and let me know how it turns out.

How do you keep gluten free pasta from getting mushy?

Can you use a different type of seafood?

You can use any seafood for this recipe. I like cod because it breaks up into chunks easily, but you can also use shrimp, scallops, salmon, or any seafood you like!


Store leftovers in an airtight container in your refrigerator. This fish Alfredo will keep fresh for up to 3 days. You can freeze this, but the pasta will thaw out with a different texture.

  1. 4 stars
    I am the pickiest eater! I was looking for a seafood dish that’s different from the dishes I tend to stick by. This meal was absolutely perfect! I added peas right into the sauce and it was divine! Thank you for this wonderful recipe!

  2. 5 stars
    I loved the idea of lightening up an alfredo by using fish with it! Turned out great and I will be making this again and again in my house!

  3. 5 stars
    I was looking for a recipe using cod in a Fettuccine Alfredo dish. This was just about perfect. I used half & half instead of heavy cream to lighten it up a bit. I also doubled the garlic and parmesan to kick it up a notch and squeezed in the juice of half a lemon and gave it a toss just before serving. Thanks!

  4. I am not sure why I am afraid to attempt making fish. I guess I haven’t bought it enough to feel comfortable. But I love fettucini, so I am sure it will be a delicious recipe.

  5. Oh my! Cod AND Fettuccini mixed all in one meal?! I think I’m in heaven!! I gotta try this recipe for sure. YUM
