|Quick enough for a week night and enough to feed a crowd.|
Butter a 2 quart casserole dish. Cook broccoli in salted water until crisp tender and drain. Saute onion in the Tbs butter until translucent and soft. Cook the spaghetti until al dente and drain. Put spaghetti in casserole, top with slices of American cheese. Pour the half and half or cream over. Add the onion and the broccoli. Top with the shredded cheddar cheese. Bake in a preheated 350 degree oven for about 25-35 minutes until bubbly and lightly browned on top. Take casserole out of oven and let sit 5-7 min. *Note- because oven temps may vary, you may need to add 5 min to cook time.
