Pre-heat oven to 350°, lightly grease a 8 x 6 inch casserole dish.
In a large pot of salted water first boil the broccoli florets until al dente, drain well and set aside, in the same water cook the pasta al dente, drain well.
In a small pan with 1 tablespoon of oil cook pancetta (bacon or sausage) until lightly golden, remove from pan and drain on paper towel lined plate.
In a medium pot on medium heat, melt butter, whisk in flour and salt until smooth then gradually add milk and stir continuously until smooth and thickened. Gently fold in broccoli and pasta, then gently fold in Pancetta, turn into the prepared baking dish and sprinkle with Parmesan cheese and top with fresh thyme. Bake for approximately 15 minutes (I also broil it for about 2-3 minutes to brown the top). Serve immediately. Enjoy!
