- broccoli – This hearty vegetable is mild in flavor and pairs perfectly with all of the creamy ingredients – we steam the broccoli first to make sure it soft and delicious.
- cream of mushroom soup – Pick up a can of our favorite brand at your local grocery store or try out our homemade dairy-free cream of mushroom soup recipe.
- mayo – Who can say no to another layer of creaminess and a slight tangy flavor. If you’re feeling ambitious, use our basic Whole30 mayo.
- cheddar cheese – This is our favorite variety, but feel free to customize with a different sharp cheese variety like Gruyere, Parmesan, Asiago, or Gouda.
- Ritz crackers – Crunchy, flakey, and the perfect topping to this classic recipe.
- butter – A necessary addition to get your Ritz crackers extra crispy on the top.
Broccoli Casserole Made Ahead Of Time
Make this broccoli casserole ahead of time by assembling all of the ingredients together as mentioned in the recipe card, saving the ritz cracker topping for when you’re ready to bake. Once assembled, cover and place your casserole in the fridge for a day or two in advance. When you’re ready to bake, let it come to room temperature for about 30 minutes on a countertop, add the Ritz topping, and cook as directed.
How To Make Broccoli Casserole
Start by steaming the broccoli by filling a saucepan with just enough water to cover the bottom. Add your steam basket on top of our sauce pan and place your broccoli inside of the steam basket. Cover and bring to a boil and steam until your broccoli is quite tender.
Drain the broccoli and place it into the bottom of a casserole dish. Pour your cream of mushroom soup, mayo, and cheddar cheese over the top and stir to combine.
Recipe Tip: Shred Your Own Cheese
Pre-shredded cheese contains additives to keep it from clumping together in the bag. For the creamiest, melty cheese, take the extra minute or so to shred your own cheese using a simple cheese grater. Plus, you usually get more for your money buying block cheese vs. pre-shredded.
Crush up your Ritz crackers and cover them over the top of your casserole.
Finally, drizzle with melted butter to get the crunchiest, golden brown topping.
Place in the oven, middle rack and uncovered, for approx. 30 minutes or until nice and bubbly.
Let cool for a few minutes and enjoy!

How early can I prep this dish before having to put it in the oven?
Hi Shannon – you could prep in the morning/night before and then just wait and add the crackers + butter right before you put it in the oven!
