If you’re like me, casseroles always show up on the table at holiday gatherings and pot luck parties. This broccoli bake is always a favorite side dish to serve and is a great alternative to the traditional green bean casserole. 

This is one of those handed down recipes I got from a girl friend years and years ago. She served it for a luncheon and I think everyone there asked her for the recipe.

Add it to your dinner party menu for holidays and entertaining.


It goes together quickly and easily and it makes plenty for a small crowd.

  • Frozen chopped broccoli. Let it thaw in the fridge overnight, or heat is according to package directions.
  • Eggs. You’ll use 2 large eggs lightly beaten so they integrate easily into the mixture.
  • Cream of Mushroom soup. This is what makes this recipe such a classic! I don’t recommend using low sodium for this because there’s no other salt added to the recipe.
  • Dried onion. This should be a staple ingredient in your spice cabinet. It adds flavor without having to chop onions.
  • Mayonnaise. Use regular mayo for a full creamy flavor and texture. If you really want to use light mayo that’s fine too.
  • Sharp cheddar cheese. Get a block and shred it your self. That’s very important because it adds so much more flavor, it melts better, and you actually get more volume! An 8-ounce block gives you more cheese than an 8-ounce package of pre-shredded.
  • French’s fried onions. I love these so much I can eat them right out of the can! A large can gives you enough to mix into the casserole and to top it at the end.

You basically mix everything together and pop it in the oven. At the end you’ll top it with some extra fried onions so you get that delicious crunch on top.

I really can’t say enough good things about this broccoli casserole recipe. Everyone loves it when I make it as part of the holiday buffet alongside my creamy mac n’ cheese and sweet potato casserole.
