Now, I did this in a 9x13 pan because we have a large family but if you want to cut the ingredients in half you can and it will fit nicely into an 8x8. Also a nice variation is to add cauliflower. It is so good.
2 Bags frozen broccoli - the steam-able ones work great.
1 Cup Mayo
1 Can Cream of Mushroom Soup
Velveeta - I use about 4 oz, softened
1 cup shredded cheddar cheese
1 packet Shake N Bake seasoning mix -chicken or extra crunchy varieties work well.
Preheat oven to 350, lightly grease pan.
Steam broccoli in microwave, drain. then combine with mayo, soup, shredded cheese and about 1/2 of the shake n bake packet. melt Velveeta in microwave until it is soft and combine with other ingredients. Top with more of the shake n bake crumbs. Bake for 45 minutes or until cheese is brown and it is bubbly.
Seriously, one of the best recipes for broccoli casserole I've ever had.
