One Skillet Lobster Mac and Cheese Recipe

One skillet lobster mac and cheese is a huge win, but an even bigger win for the cast iron skillet. This recipe marks the start of my “journey” to see how many cast iron skillet recipes I can create that require no extra pans. Why? I love cooking things in one pan and I hate cleaning dishes, like everyone else in the world. Dishes are the death of me. I stare at them…they stare back at me…I walk away and hope they clean themselves.

That said, cast iron is so versatile, inexpensive, and indestructible. it’s becoming my favorite pan in the kitchen. My challenge for this particular dish was to see if I could condense a macaroni and cheese recipe to a single cast iron skillet. I was inspired by Scott’s famous mac and cheese recipe.

Scott’s personal hack is to not actually cook the pasta elbows separately before combining with the cheese and baking. In fact, the cheese sauce cooks the pasta while it bakes in the oven, amazing right? So the one big question was: Can I cook the cheesy sauce in a skillet and bake it in the same skillet without everything burning or sticking? YES.

Lobster mac and cheese is the perfect way to eat leftover lobster (if there ever is any). I personally don’t think I would buy and steam lobster for the sole purpose of making lobster mac and cheese, however don’t let me stop you. Sometimes we will steam an extra lobster on lobster night and peel it and freeze it for later use.

As Scott will tell you, the cheese is very important. I use extra sharp white cheddar, ‘orange’ sharp cheddar (for color), and then balance with a smoother fontina or gruyere. Maybe it’s just me, but the sharp cheddar cheeses give homemade mac and cheese a gourmet finish on traditional comfort food. Can I say classy comfort food?

WINTER IS COMING. Is there a better time to start thinking about some hot savory fall dishes?
