For adventurous cooks this decadent gluten free Lobster Mac and Cheese is fun to make. Lobster season varies by region so when you can buy it, make this fancy pasta dish for your lobster loving friends. You can use lobster tails but boiling a whole lobster is all part of the fun!
I serve this creamy dish with a simple green salad and homemade vinaigrette dressing. Another option is long skewers of Tomato Bocconcini and Basil served as a starter or salad. These can also be made on toothpicks for a pop-in-your-mouth delight while you're waiting to see if the lobster screams when thrown in the boiling water.

Ingredients
Two basics for cooks new to gluten free are a good gluten free pasta (that everyone wants to eat), and a white sauce recipe. Then you're cooking!
- Butter - The real thing.
- Garlic & onion - The key to so many savoury recipes.
- Cornstarch - My go-to thickener for sauces.
- Cream & milk - For a decadent sauce you want that fat so buy some real cream as the recipe says.
- Sharp cheddar cheese & Gruyere cheese - The combination of cheeses elevates the basic sauce for this recipe.
- Lobster, whole or tails - Buy fresh when you can.
- Gluten free pasta - There are great brands out there. Try them all and pick your fav.
- OPTIONAL: Gluten free breadcrumbs, Parmesan cheese & parsley

Instructions for Cooking Lobster
Lobster - Cooking a whole, live lobster is a culinary challenge, only in your mind. They are simply boiled and people do it on the beach. Getting the lobster meat out of the shells is more of a challenge. If you're not up to it, lobster tails make the same delicious dish.
Gluten Free Pasta - Pasta has come a long way in the gluten free world. With so many brands available you need to put some effort into finding one you like. Follow the package directions, which are not all the same, then cook accordingly. Do head-to-head comparisons and have a little fun refining your palate.

Cheese Sauce - My basic white sauce recipe reminds you not to stir too vigorously and to add the milk in stages to ensure your sauce is nice and thick. Check it out if you have not mastered the basic recipe.
Substitutions & Variations
Sauce - This recipe started with my basic cheese sauce, the one I use for everyday macaroni and cheese. I added a bit of onion and garlic, used a combination of cheeses, and folded in some lobster. Substitute as you like.
Equipment for Lobster
It wouldn't be a lobster boil without disposable lobster bibs and lobster shelling tools. These are the tools to get lobster and crab meat out of the shells. Make your dinner a real culinary experience that ends with a big dish of this lobster mac 'n cheese.
Top Tip for Gluten Free Pasta
Find a pasta the whole family wants to eat! There are many gluten free pastas available so you can find one. Check out Italian stores too since Italy has a good awareness of gluten free and makes quality pasta. Once you have one, buy it in larger packages to decrease the price.
