Equipment

2 medium saucepans
1 Large frying pan or pot, if planning to transfer to casserole dish to bake.
1 casserole dish optional

Ingredients

8 oz macaroni noodles
1 Tablespoon olive oil
2 small raw lobster tails (or 1 large 8-10 oz tail)
4 Tablespoons salted butter salted
1 Tablespoon fresh minced garlic
¼ cup all purpose flour
1 teaspoon salt
½ teaspoon ground pepper
1 teaspoon chicken bouillon
1 teaspoon onion powder
3 cups whole milk
¼ cup sour cream
2 cups Havarti cheese (6 oz) NOT pre-shredded
2 cups colby jack cheese, grated (6 oz) NOT pre-shredded
¼ cup parmesan cheese, grated (1.5 oz) Not pre-shredded

Instructions

Preheat the oven to 350° F
Bring two medium-sized pots of salted water to a boil.
In one, cook noodles for 7 to 8 minutes, until tender. Drain and toss with 1 Tablespoon of olive oil. Cover and set aside.
In the other pot, cook lobster tails for 3-4 minutes, until internal temperature reaches 145° F. Drain and let cool before separating meat from both tails, then dice into small bite-sized pieces. Set aside.
In a large oven-safe frying pan (or a pot if using a casserole dish to bake) melt butter over medium heat, and add minced garlic. Cook about 1 minute until fragrant, then add flour, salt, pepper, chicken bouillon, and onion powder. Stir and cook for another minute.
Slowly pour milk into the flour mixture, whisking at the same time to prevent clumping until all the milk is added. Add sour cream and stir. Continue whisking and heating the sauce until smooth and slightly thickened, 2-3 minutes.
Remove from heat. Add in the cooked noodles and lobster meat and mix together. Adding these first helps prevent the cheese from becoming overheated and oily.
Add in 1 cup each of the colby jack and havarti cheese, then stir until melted.
If your frying pan is oven safe, proceed to sprinkle the remaining cup of havarti and cup of colby jack cheeses on top of the noodles and sauce.
If using a pot, transfer to an oven-safe casserole dish before sprinkling the cheeses on top.
Transfer to the oven and bake for 10-15 minutes, until cheeses are melted and bubbly around the edge.
Serve warm. Garnish with fresh sprigs of thyme optionally.

Notes

Best served fresh, but it can be made ahead.

To make ahead, make the recipe as directed, but do not bake in the oven. Let cool and cover, then refrigerate for up to 3 days.

To reheat: Bake at 350 F. for 20-25 minutes until heated through and bubbly.

Freezing not recommended due to the pasta and dairy, texture could become grainy when thawed.
