Recipe Variations:

I love how simply this broccoli casserole is to make and it’s super easy to adjust to the ingredients you have on hand.

  • Use cream of chicken soup, cream of celery soup or broccoli cheese soup. 
  • Skip the can soup and use 1 teaspoon of chicken base (or a bullion cube) with 1 cup of heavy cream, increase milk to 1 1/2 cups total.
  • A combination of cauliflower and broccoli.
  • Add cooked carrots, celery or zucchini in addition to the broccoli. 
  • Use farro in place of the rice. 
  • Try smoked gouda, Swiss or colby cheese. 
  • Replace the French fried onions with 1 1/2 cups seasoned bread crumbs mixed with 2 tablespoons of melted butter or crushed Ritz crackers. 
  • Toasted sliced almonds are also a great addition to this casserole.

How to Cook Rice: 

I love to make extra rice anytime we are having it for dinner. It is great to have on hand to stretch leftovers or to use in a casserole. I always buy long grain white rice but use what you have on hand.

To cook rice add 1 part rice to 2 parts water, bring to a boil. Cover and lower to simmer. Cook for 15 minutes. Remove from heat and set aside 5 minutes. 

How to Cook Broccoli:

Use fresh or frozen broccoli for this recipe. To cook either, heat a pan of boiling water. Add broccoli florets and cook for 5 – 7 minutes or until heated through. Drain well. 

How to Store and Reheat:

Store leftover casserole in an airtight container up to 3 days in refrigerator. Reheat casserole by adding a couple of tablespoons of water or milk to a skillet. Add casserole and place over medium heat. Stir frequently until heated through.
