Step 1

Preheat oven to 350 degrees F.

Step 2

In a large pot of boiling, unsalted water cook the pasta to al dente (about 8 minutes). Remove from heat and drain.

Step 3

While the pasta is cooking, in a separate pot, melt the butter. You need to make a roux. Whisk in the flour, turmeric, and mustard and keep whisking for about five minutes. Make sure it's free of lumps.

Step 4

Stir in the milk, onion, bay leaf, and paprika. Simmer for ten minutes and remove the bay leaf.

Step 5

Whisk your egg in a cup and slowly add in the egg to avoid scrambling it.

Step 6

Stir in 3/4 of the cheese. Season with pepper. Fold the macaroni into the mix and pour into a 2-quart casserole dish. Top with remaining cheese.

Step 7

Melt the butter in a saute pan and toss the breadcrumbs to coat. Top the macaroni with the bread crumbs.

Step 8

Bake for 30 minutes. Remove from oven and rest for five minutes before serving.
