Ingredients And Substitutions
These are the main ingredients and substitutions for Gluten Free Broccoli Casserole. Scroll down to the recipe card for a full list of ingredients and instructions.
I prefer to use fresh broccoli florets for this recipe, as they tend to hold their crispness level more. However, you can use frozen if necessary.
Whole milk makes the cheese sauce extra creamy, however if dairy free you can swap for coconut milk, oat milk or almond milk.
Tapioca flour is a gluten free flour that is used to help thicken the cheese sauce. Arrowroot starch and corn starch also work great in replace. Alternatively, all purpose flour will work too if not gluten free.
Grass fed butter is recommended because of it’s fat content and for added flavor. Regular butter works in replace, or you can use ghee or plant based butter.
Instead of using chicken broth, I prefer to use a bone broth concentrate as it adds a ton of added flavor without having to use too much seasonings or salt. I used Zoup brand but you can use chicken bouillon or just chicken or veggie broth.
Greek yogurt helps make the sauce extra creamy. Sour cream, or plant cream also works in replace. Alternatively you can use heavy cream.
Don’t use pre-shredded cheese for this recipe as it’s coated in a certain ingredients so it won’t melt as good. Instead, use fresh grated cheese. It makes all the difference.
Black pepper, onion powder and garlic powder are the only additional seasonings you’ll need.
Finish off this casserole with crushed gluten free crackers. If not gluten free you can use ritz.

How To Make
ONE: Start by chopping and washing the broccoli florets. Then, add them to a pot of boiling water and let soak for about 3 minutes or until they turn bright green in color. Remove them immediately and add them to a non-stick pan.

TWO: Next, in a large saute pan over medium to low heat add in the milk and tapioca flour. Mix until the milk thickens in texture. Then, add in the butter and chicken broth concentrate. Mix well and add in another cup of milk along with the greek yogurt and mix until combined.


THREE: Mix in the cheddar cheese until fully melted and add in the seasonings. Taste to ensure you like the flavor or add in more seasoning if needed.

FOUR: Pour cheese over broccoli florets and mix well until fully combined. Sprinkle the tops with more cheddar cheese and then finish it off with the crush crackers.



FIVE: Bake at 400F for 30 minutes. Remove from the oven and serve warm.


Tips And Tricks
It’s recommended to use fresh broccoli florets as these tend to stay a bit more crisp than frozen.
The cheese sauce comes together in just a few minutes, so prepare the broccoli first.
Taste the sauce as you go along to ensure it doesn’t need anymore seasonings.
Using freshly grated cheddar cheese is highly recommended. Pre-grated cheese won’t melt the same.
If not using a non-stick pan, then make sure to grease your dish well before adding in the broccoli to ensure nothing sticks.

Frequently Asked Questions
Sure! I haven’t tried any other one for this specific recipe, but I bet cauliflower, green beans or even a vegetable medley would work.
Just swap the milk for a dairy free milk, the greek yogurt for a plant based yogurt and the cheese for a dairy free cheese alternative.
