2 c milk
3 tbsp butter
1/4 c flour
1 1/4 tsp salt
8-9 oz uncooked pasta
4 oz shredded colby & jack cheese
1 1/2 oz grated parmesan cheese (about 1/2 cup)
1/4 c panko or breadcrumbs, optional
Cook pasta according to package directions. Drain and rinse in cold water. Allow pasta to drain while preparing sauce. Heat milk in microwave for 2 minutes. Melt butter in a heavy dutch oven over medium heat. Add flour and whisk until golden brown. Add hot milk, whisking constantly until milk is fully incorporated. Cook 3 minutes until sauce thickens. Add salt. If not salty enough, add another 1/4 tsp of salt. Stir in cheeses. When mixture is smooth, gently stir in cooked pasta. Heat until pasta is hot, about 3 minutes. Serve immediately.
You may also place in 2 1/2-3 quart baking dish, sprinkle with panko or breadcrumbs, and bake at 400 degrees for 25-30 minutes.
