Tips For Today:
-Read through the instructions prior to baking, it will make the process easier and more fun overall!
-You can create bread crumbs from any savory bread recipe of your choosing that works with your diet. This version is quick, easy + delicious. Links to our Paleo + Low-Carb versions below.
-For the Paleo version, make sure to use plain almond milk and omit the cheese and add 1 tbsp Italian Seasoning + 1/4 tsp salt to the bread crumb mixture and then follow recipe as written. You can make bread crumbs from our Paleo Bread Recipe or our SCD bread Crumb Recipe.
-Low-Carb Version uses our SCD Bread Crumb Recipe. Keep in mind that the 2 3/4 tbsp of tapioca starch in this recipe will add about 26g of carbs to the entire recipe which is ten servings– this comes to 2.6g carbs per serving. You will have to factor in the carbs from the broccoli and almonds as well. Cheese and chicken is negligible. Overall, it’s a good low carb choice.
-And feel free to mix and match ingredients, one of our favorite casseroles growing up was turkey and asparagus, for example, so yummy!

  • Yield: 8 Servings 1x


7.3 net carbs per serving, nutrition facts below recipe


  • Chicken:
  • 2 large chicken breasts (skinless + boneless)
  • 1 1/2 teaspoons lemon pepper
  • 2 tablespoons olive oil
  • Broccoli:
  • 2 cups broccoli florets (lightly cooked or blanched)
  • Topping:
  • 3 cups bread crumbs (we have paleo + low carb versions, see tips section in post above for links)
  • 2 cups shredded cheese (we use a blend of cheddar + parmesan) dairy-free can use “Daiya” brand. See tips section in post above for Paleo version.
  • 1/4 cup melted butter (or ghee), Earth Balance for dairy-free
  • Sauce:
  • 1/4 cup melted butter or ghee (Earth balance for dairy-free)
  • 2 tablespoons + 1 teaspoon potato starch (not potato flour) No substitutes
  • 2 cups whole milk or half + half for less carbs (plain soy milk or coconut milk with plain almond milk for dairy-free)
  • 1/2 teaspoon salt or to taste
  • 1/4 teaspoon pepper
  • 1/4 teaspoon paprika
  • 1/4 teaspoon onion powder


  1. Preheat your oven to 350 degrees
  2. Chicken: Place your chicken breasts in an 8×8 baking dish (or something similar). Brush the tops of your chicken breasts with olive oil and then sprinkle the lemon pepper over top. Place into the oven uncovered for about 30 minutes or until just cooked through.
  3. Remove chicken from oven, place onto clean cutting board and slice into bite size pieces. Set aside.
  4. Broccoli: Blanch or lightly steam broccoli florets, set aside.
  5. Topping: In a large bowl, add your bread crumbs, shredded cheese and 1/4 cup of melted butter. Toss until evenly incorporated. Set aside.
  6. Sauce: Make sure to have your milk and your potato starch measured in separate dishes before you start the sauce.
  7. In a medium sized pot, melt 1/4 cup of butter at medium heat. After butter is melted, slowly whisk in the potato starch, stir rapidly for about 30 seconds. Then add in your milk, about 1/2 a cup at a time. The mixture will thicken very quickly, so whisk very vigorously, this way it will be nice and smooth. After you have incorporated all the milk, add in your salt, pepper, paprika and onion powder to taste. Allow it to come to a boil while stirring and then remove from heat. Then add in your chicken and broccoli and combine with large spoon until incorporated evenly.
  8. Putting Casserole Together: Press half of your bread crumb mixture on the bottom of your casserole dish. Add your chicken + broccoli filling and spread it evenly over the bread crumbs. Finally, sprinkle the remaining bread crumbs evenly on top.
  9. Bake at 350 degrees for 35 minutes until golden brown and bubbling around the edges. (For low-carb + paleo version, cover for the first 20 minutes with foil, then uncovered 15). Serve hot and store leftovers in covered dish or airtight container + refrigerate. Enjoy!
