Recipe walkthrough: Instructions

This is an overview of the recipe steps. For more detailed instructions visit the recipe card at the bottom of this post.

  • Step 1: Heat butter in a skillet over medium-high heat.
  • Step 2: Sauté onion and celery until wilted.

  • Step 4: Slowly add the evaporated milk, then egg yolks, colby cheese, crawfish tails and seasoning. Stirring all the time.

  • Step 5: Pour into a greased 1.5 quart baking dish.
  • Step 6: Mix the parmesan and breadcrumbs and sprinkle over the top.
  • Step 7: Bake in a preheated oven for 15 minutes, until golden brown.
  • Step 8: Remove and sprinkle with a little parsley.

Hint: Using a food processor to finely chop the onions and celery will ensure they're nice and fine for a great mouth feel, and not bulky in the crawfish au gratin.

Recipe variations and substitute ideas

  • Green Onions - instead of parsley.
  • Lemon Juice - to add a little acidity.
  • White Wine - again, for acidity.
  • Cajun Seasoning - add a touch of this for some extra spice.
  • Hot Sauce - for added heat.
  • Whipping Cream - you could use this instead of evaporated milk.
  • American Cheese - try this instead of the Colby cheese.
  • Red Pepper - it's a sweeter pepper.
  • Crab Base - use this for added flavor.
  • Celery Salt - for more flavor.
  • Garlic Powder - to add another spice.
  • Onion Powder - to add another spice.
  • Yellow bell peppers - sweeter than the green.
  • Chicken Base - try this instead of some of the evaporated milk.
  • Shrimp - add some raw shrimp when you add the crawfish.

Like mentioned, I like to use a food processor for this recipe, to ensure the onions and celery are nice and fine.

I also used a large skillet and a 1.5 quart baking dish. I have some affiliate links in the recipe card below, for more information.

How to store leftovers

Once cooled completely, store in an airtight container in the refrigerator for up to 3 days.

Mel's kitchen notes

If you're using the Au Gratin more as a dip and want a more spreadable consistency use a little less evaporated milk. In reverse, if you are using it more like a sauce and want to pour over, say, a piece of fish, then use a little more.
