What makes this recipe so yummy
- Using Gruyere cheese really takes this recipe up a notch. Gruyere adds a delicious creaminess as well as delicate nutty flavor.
- Get a good Andouille Sausage, it makes the world of difference.
- I use my homemade Cajun seasoning, which is next level. You could use your favorite store-bought blend though.

How to store leftovers

When reheating, sprinkle with a little whole milk first to avoid it drying out. Cover and cook in the microwave, just until warmed through.

Frequently asked questions: FAQs
For this particular recipe, it's not recommended, as the noodles will need a lot more fluids to cook in this way.
You can. It won't taste as good though. The skillet frying really adds another flavor dimension. If you need to skip though for times sake - it's ok.
