- 2 tablespoons table salt: Added to the pasta cooking water to enhance flavor.
- 1/4 cup salted butter: For a rich and creamy base; melted butter is an essential component for the roux.
- 2 cups whole milk: Provides the creamy texture for the cheese sauce. Feel free to use 2% if you prefer, but whole milk yields the best flavor.
- 1 tablespoon yellow prepared mustard: Adds a touch of tanginess that enhances the overall flavor.
- 1 teaspoon table salt: For seasoning the cheese sauce to perfection.
- 1/2 teaspoon ground black pepper: A hint of spice that rounds out the flavors.
- 1 1/2 cups extra old cheddar cheese (grated): The star of the show! Opt for a well-aged cheddar for a sharp, bold flavor.
- 1 tub sharp cheddar processed cheese spread: Melts smoothly into delicious gooeyness; can be swapped for another similar processed cheese if needed.
- 8 ounces cooked lobster meat (chopped): Fresh or frozen, the lobster adds a sweet and delicate twist to the dish.
- 2/3 cup cornflake crumbs: Gives a delightful crunch on top; feel free to substitute with panko breadcrumbs for a different texture.
- 2 tablespoons salted butter (melted): Used to moisten the cornflake topping for extra golden crispness.
- 3 tablespoons + 1 1/2 teaspoons all-purpose flour: This will thicken your cheese sauce, creating that delightful creamy consistency.
- 1/4 teaspoon MSG: Optional, but it enhances the umami flavor for that extra punch.
How to Make Lobster Mac and Cheese
- Preheat the Oven: Start by preheating your oven to 375ºF (190ºC). Grease a 9 x 13-inch (23 x 33 cm) baking dish and set it aside to prepare for the cheesy goodness.
- Cook the Macaroni: Bring a large pot of water to a rolling boil. Add 2 tablespoons of salt before tossing in the elbow macaroni. Cook according to package directions until al dente, usually around 7-8 minutes. When done, reserve 1/2 cup (125 ml) of the pasta water and drain the rest in a colander.
- Make the Roux: Return the empty pot to medium-low heat and melt 1/4 cup of salted butter until it’s bubbling lightly. Gradually stir in 3 tablespoons plus 1 1/2 teaspoons of all-purpose flour, allowing it to cook gently for about 2 minutes, stirring often to avoid browning.
- Create the Cheese Sauce: Pour in 2 cups of whole milk and the reserved pasta water. Add the mustard, 1 teaspoon salt, 1/2 teaspoon ground black pepper, and MSG. Whisk well until the mixture becomes smooth and creamy, over moderate heat.
- Melt the Cheeses: Slowly add 1 1/2 cups of grated extra old cheddar cheese and the tub of sharp cheddar processed cheese spread. Stir with a spatula until fully melted and you have a cohesive, creamy sauce.
- Combine: Gently fold the drained macaroni and chopped lobster into the cheese sauce, ensuring everything is well-coated. Transfer this heavenly mixture into the prepared baking dish, spreading it evenly.
- Prepare the Topping: In a small bowl, mix 2/3 cup of cornflake crumbs with 2 tablespoons of melted butter until evenly moistened. Sprinkle this mixture generously over the macaroni and cheese.
- Bake and Broil: Place the dish in the preheated oven and bake for 18 to 20 minutes or until it’s hot and bubbling around the edges. Turn on the broiler for an additional 2 to 3 minutes, keeping a close eye to prevent burning, until the topping is golden brown.
- Serve: Enjoy your Lobster Mac and Cheese hot from the oven! Pair it with a simple green salad or some steamed broccoli for a well-rounded meal.
Storing & Reheating
Store any leftovers in an airtight container at room temperature for up to 2 hours. For longer storage, refrigerate the dish for up to 3 days or freeze it for up to 3 months. To reheat, place in a preheated oven at 350ºF (175ºC) for about 20 minutes or until warmed through. If frozen, thaw overnight in the fridge before reheating. Keep in mind, while the flavors remain delicious, the texture may slightly change, so consider refreshing it with a splash of milk or a sprinkle of cheese before serving.
Chef’s Helpful Tips
- Avoid overcooking the macaroni; you want it al dente to maintain its texture during baking.
- If using frozen lobster, ensure it’s fully thawed and well-drained to prevent a watery sauce.
- For added flavor, consider mixing in your favorite herbs or spices into the cheese sauce.
- If you prefer a more velvety texture, you can blend the cheese sauce briefly for even creaminess.
- This dish can be made ahead; prepare it up until baking, then cover and refrigerate for up to a day before baking.
- Adjust the amount of cheese based on your preference — more cheese means more delicious!
Lobster Mac and Cheese is a definite crowd-pleaser with its creamy richness and delightful crunch. You’ll love the way it combines familiar comfort with a touch of elegant seafood flair. Don’t hesitate to experiment with the spices or toppings to make it truly your own.
