EXCELLENT, my family loves it! It will be a regular always! We are all doing KETO
I also did a variation w canned low sodium corned beef. Cut out the salt in the recipe.
So glad I found this page! ❤️

Thank you Lisa, I'm glad you enjoyed!

Anyone try it with broccoli in place of cauliflower and how did it taste? Thanks

Hi Valerie, broccoli is a great option! I haven't tried it in this recipe but I often use it in other recipes as an alternative.

Can this be frozen? If so, would you suggest how? Thank you!

Hi Tiana, we haven't tried freezing this one but my guess is that there might be a slight separation due to the dairy included. I'd still freeze it because I don't think it will be significant.

Great i give it 5 stars it came out great i double the recipe

Thank you, I'm glad you enjoyed!

Hi! I was wondering if there were other variations you have tried of this recipe. I love the buffalo chicken one. However, I was wondering if you have tried substituting bbq for the buffalo sauce? Would that work alright? Then use white or red onions instead of green onions.

BBQ sauce sounds delicious! Just make sure to use sugar-free or try this recipe: Low-Carb Spicy Chocolate BBQ Sauce
When it comes to onions, red, white or yellow sound great (just remember they are a little higher in carbs compared to green onions). I hope this helps!

I made this last night and it was very tasty! It passed the husband test as he didn’t ask “is there cauliflower in this?” and he said it was very good. The portion size is large, so good for a day when you feel hungry. The texture surprised me a bit, it was quite dense, but still moist. I cooked mine at 200°C for 45 minutes and the cheese was much browner than in your picture. I lowered the temperature as I felt 225°C is a very hot oven (400°F =204°C, so I went for a lower setting). I maybe should have taken it out sooner....I let it cool for 10 minutes before serving. The blue cheese and spring onion topping are a must. Very good...thank you!

Diane, thank you for your lovely feedback and temperature tips!

I really liked the recipe, came out really great. Great Flavor. Really large portion sizes so you won't be hungry after this meal. Only thing that struck me was it tasted a tad egg-y when reheated. But still a really great recipe.

Thank you! I think you could use fewer eggs and add some shredded cheese.

I made this again, and as you suggested, I reduced the amount of eggs  and added some cheddar cheese (and added a splash of cream) to the mixture. It made it a little less dense and I preferred it. A very good recipe!

Thank you Diane, I'm glad you did!

I don't see how many total calories are per serving. Can you tell me that? Trying to input my dinner into my Fitbit (I made this last night and it was DELISH!)

Hi Trista, all nutrition facts, including Calories, are listed in the table 😊

Hello just wondering what is the serving size? 1 cup half cup? Thanks

I don't have the weight but I just pre-cut it in 6 equal pieces, ideally after leaving it to cool for 15-20 minutes.
