Turkey, Broccoli & Mashed Cauliflower Layered Casserole

posted in: Main Dish


Casseroles are one of my favorite things to eat, especially because they make the very best leftovers! I’ve eaten this turkey, broccoli & mashed cauliflower casserole cold, right out of the pan, and it was still amazing! Remember that super easy mayo recipe I posted yesterday? You’ll need it for this recipe! It takes this casserole up another notch and gives it such an amazing flavor.

This layered casserole combines all of my favorite flavors, and it’s a great way to get in lots of veggies without even realizing it. I mean, who wouldn’t want to eat a layered casserole? Although I love using turkey in this dish, it could easily be swapped out for leftover chicken, if that’s what you have on hand!

So many of you have been asking for more casserole recipes, so here’s another one to add to the list! This casserole could also easily be made in advance, so you can just pop it in the oven whenever you’re ready to eat. It also makes an incredible meal to make for friends, which is just what I need right now, since so many of my friends are having babies. I love cooking for others and taking that stress off of them for a couple meals! After all, food is my love language. 😉

I hope you’re all having a great holiday season! Happy cooking!

Turkey, Broccoli & Mashed Cauliflower Layered Casserole


    For The Mashed Cauliflower:
  • 1 large head of cauliflower, cut into florets
  • 2-3 tbsp ghee
  • Sea salt to taste


  1. Preheat your oven to 350 degrees.
  2. Let’s start by making the cauliflower mash! Place a couple inches of water in a pot, and bring to a boil over high heat. Once the water is boiling, place a steamer insert into the pan and add the cauliflower florets. Cover the pan and allow it to steam until the cauliflower is soft and easily pierced with a fork.
  3. Drain the water out of the pan and add the cauliflower. Turn the stove back on to medium heat and allow any extra water to evaporate out of the pot. This is the key to a fluffy mash! Add the ghee/butter to the pot, and blend with an immersion blender until smooth**. Add salt to taste. Set aside while you make the casserole base. **Another option is to place the cauliflower in your food processor or blender and process/blend until smooth.
  4. Now let’s make the base for the casserole! Melt the ghee in a large pan over medium heat. Add the onion and celery to the pan and sauté until tender, about 5 minutes. Add the garlic to the pan and sauté until fragrant, about 30 seconds. Add the broccoli to the pan and stir well. Turn off the heat.
  5. Add the turkey, mayonnaise, eggs, poultry seasoning, onion powder, dried sage, garlic powder, sea salt & black pepper to the pan. Stir the mixture really well.
  6. Pour the turkey mixture into a 9”x 9” dish, using a spatula to smooth the top. Scoop the cauliflower mash on top of the turkey mixture in the dish, using a spatula to smooth the top of the casserole. Bake uncovered for 45 minutes-1 hour, or until the top of the casserole begins to lightly brown. Let stand for 5 minutes before serving. Enjoy!

    If you wanted to use ground beef instead of turkey in this recipe, would you recommend 1lb or more? Thanks!

      Hi Jaime! Yep, I’d use a pound of ground meat 🙂

    I really loved the Thanksgiving type flavors in this from all the spices but boy was it super wet and I had to bake it twice as long as the instructions. I’m wondering about a crockpot alternative?

      Hi Alisha, so sorry to hear that yours came out wet! I’m not actually sure what could have caused this, as the ingredients don’t have a ton of moisture, besides the egg (which sets completely). Was the cauli mash that you used really runny maybe? I haven’t tried the crockpot method, but if you happen to, I’d love to know how it turns out!

    This was delicious. I only added about 1/4 to 1/3 cup of the mayonnaise since someone mentioned it was wet. I used rotisserie chicken. I would like to try it with ground turkey meat. Mine came out very good and not wet. I made sure I heated the cauliflower in the pot after it was steamed to dry it out. I love the flavors.

    If I have an egg sensitivity what would you substitute?

      Hi Mary! Unfortunately the egg isn’t something that’s easy to substitute. You could leave it out, although it wouldn’t be a casserole – but it’d still be delicious! 🙂

        Would a flax egg work here instead? I don’t know if it’s paleo or not.

        I’m not sure as I haven’t tried it myself!
