Preheat oven to 350 F.

Slice broccoli into stalks. You can keep most of the stems on them if you want, either way is fine!

Steam broccoli in a pot over the stove- should take about 15 minutes. You want to be able to easily stab a fork into it, but don't let it get mushy.

Drain steamed broccoli and set aside.

Mix can of mushroom soup and milk in a small bowl. If you prefer a little more moisture, add more milk. This just thins out the soup so it can coat the broccoli well.

Put a thin layer of the mushroom mixture on the bottom of an oven safe casserole dish.

Then add a layer of broccoli (about half). Continue by layering three slices of cheese and more mushroom mixture. Then put the rest of the broccoli over that layer, more cheese and mushrooms, and finally the fried onions.

Cover and bake for about 30 minutes or until it's golden brown and bubbling. Serve immediately!
