Step 1

Preheat the oven to 375f.

Step 2

Meanwhile, fill a pot of water and bring to a boil. Once boiling, cook pasta for one minute less than directed on package for al-dente. Strain the noodles and rinse in cold water. Set aside.

Step 3

Heat a large oven safe skillet over medium heat. Melt the butter in the skillet and allow to simmer until slightly darkened and fragrant.

Step 4

Whisk in the flour and cook for about a minute before whisking in the milk in batches. Once the milk has been completely whisked in, simmer it until it thickens enough to coat the back of a spoon.

Step 5

Reserve about a cup of cheese, then add the remaining cheese to the milk mixture. Whisk the mixture until completely smooth. Add the sliced jalapenos and continue simmering for 2-3 minutes, stirring regularly.

Step 6

Pour the cooked pasta into the sauce, and stir until completely combined.

Step 7

Top the pasta with reserved cheese and bake at 375f for 15- 20 minutes.

Step 8

Broil at 400f for 2 -3 minutes, if you like your cheese a little crispier!
