Donna's Broccoli Casserole

My sweet friend Donna Lewis mailed this recipe to me just after I married in November 1980. She made a note that if Bill didn't like broccoli that I should chop it up after it cooks and he wouldn't know that it was broccoli. I did and he loved it. Tricia and Lee Ann like this casserole too. :)

Donna's Broccoli Casserole

2 boxes frozen broccoli
1/2 teaspoon of salt
1/2 can cream of mushroom soup
1/2 of a small yellow onion chopped fine
2 heaping tablespoons of Kraft mayonnaise
1 egg slightly beaten
1 cup shredded cheddar cheese
1/2 package of Ritz crackers crushed

Cook broccoli with salt in enough water to cover until tender and drain.
Mix mushroom soup, mayonnaise, egg, and half of cheddar cheese, and onion with spoon until well blended.
Place drained broccoli in bottom of 9 x 11 casserole and cover with the soup mixture. Top with remaining cheese and cover the cheese with ritz cracker crumbs. Lightly cover with plastic wrap and Microwave for 8 to 10 min. on high. Center should be bubbling. Remove plastic wrap and let stand for 5 min before serving.

Notes: 
I tried this recipe in the regular oven once when my microwave was out of order and It was much more dry than it is in the microwave.
Ritz Crackers are key to a great taste with this casserole. The butter in the crackers makes the difference. If you have to use another cracker you might try adding a little melted butter on top of crackers. Just a little!
