Chef Jenn’s Tips to Make This Keto Meatloaf Casserole Recipe
- Use good quality (grass-fed if you can) lean ground beef, but you can also use a combination of pork, chicken, or turkey.
- Use fresh cauliflower to make the mashed topping – frozen and thawed cauliflower will just be too runny.
- Jazz up this dish with a 1/2 cup of parmesan in the cauliflower mash.

Served this for dinner last night and it was a hit all around the table! Easily, a new favorite casserole; so delicious and easy too!
So delicious and easy to make. I love making as small individual servings in ramekins so everyone in the fam can heat up on their own.
This looks so good! I love one pan dishes, will be definitely trying this.
it looks like you made them in individual ramekins but the recipe mentions a casserole dish – is the cooking time any different? looks delish!
Good point! I’ll update the recipes to include the cooking time if you use an individual dish. Thanks for catching that!
I love the idea of mashed cauliflower on top! Definitely reminiscent of a great cozy comfort meal!
I roasted the cauliflower in the oven using this recipe, https://natashaskitchen.com/roasted-cauliflower/
Very delicious. I then followed the recipe as directed. My Husband said to add it to our top 10 “make it list!”
What a great idea to roast it first! I’m so glad you liked this recipe – and your husband, too! Thanks for coming by to comment! ~Jenn
