Ingredients

  • Cooked chicken – Leftover rotisserie chicken is great in this dish, but grilled or baked chicken will also work.
  • Heavy whipping cream
  • Ricotta cheese – Look for ultra smooth for the creamiest texture.
  • Italian blend cheese – Shredded cheese. See my tips for substitution suggestions
  • Cream cheese – Softened.
  • Zucchini
  • Basil
  • Sundried tomato – Just a wee bit for a pop of flavor and color.
  • Garlic powder
  • Onion powder
  • Pork panko – Ground pork rinds.
  • Butter – I always use salted butter.

Are Sundried Tomatoes Keto?

Tomatoes are keto, but are sundried tomatoes keto? Yes and no. They’re tomato, but dried, and the flavors and sugars are condensed, which makes them higher in carbs. Plus, they’re small, so it’d be easy to go over your carb limit with sundried tomatoes. However, there’s so little in this recipe, and they really do add so much for the flavor, so I say use them! They don’t add many carbs per serving, and the flavor is so very worth it!

Chef Jenn’s Tips

  • Make sure your cream cheese is quite soft before trying to mix it. You can soften it in the microwave in 20-second bursts (make sure to remove the foil wrapper) to help you get started.
  • When cutting zucchini, I cut it all around the center core of the seeds. I discard the seeds. They’re watery, fibrous, and not so tasty. You can slice the zucchini and then easily cut away the seedy core.
  • Chop the sundried tomato very small, so the flavor spreads throughout.
  • If your casserole starts to get too brown, cover the top lightly with foil.

Make It A Meal

There’s veg, protein and fat all in this keto zucchini casserole, so you don’t really need anything else with it. If you are looking for some tasty sides to add to it, try a delish Greek Salad, bacon-wrapped asparagus, or a creamy and delicious soup.

Variations

There’s plenty of wiggle room in this keto Chicken and Zucchini Casserole recipe. Here are some of my favorite substitutions:

  • Mozzarella, gouda, Monterey Jack or any other easy-melting cheese will work in place of the Italian blend cheese.
  • No fresh basil? Add 1/2 teaspoon of dried basil instead.
  • Use any kind of cooked chicken: baked, grilled, rotisserie – it all works! Light or dark meat is fine.
  • Don’t like pork panko? Skip it! Just sprinkle a bit more cheese on top before baking.

Storage

Store any leftover casserole in an airtight container in the fridge for 2-3 days. Just watch that your chicken isn’t already old – you should eat leftover chicken within 3-5 days of cooking it, even if it is re-cooked in this casserole.

    The ricotta and zucchini combination was a bit hit, even with my kids! And a great way to stay within my macros without feeling deprived.
