Keto Chicken Parmesan Casserole Ingredients
• The secret to a cozy, low-carb dinner!
For the Chicken Base
- Cubed Rotisserie Chicken or Chicken Breast – Use pre-cooked chicken to save time and keep the dish simple.
- No Added Sugar Marinara Sauce – Look for low-sugar options to stay keto-compliant while adding flavor.
- Italian Seasoning – A perfect flavor enhancer; substitute with dried oregano and basil if necessary.
- Minced Garlic – Fresh garlic brings an aromatic depth to the dish.
For the Sauce
- Olive Oil – Ideal for sautéing garlic; avocado oil can be used for a higher smoke point.
- Almond Flour – Adds texture and thickens the sauce; omit for a nut-free option if desired.
For the Cheesy Topping
- Grated Parmesan Cheese – Freshly grated will provide the best melty richness.
- Shredded Mozzarella Cheese – This cheese melts wonderfully for that gooey goodness everyone loves.
- Finely Crushed Parmesan Crisps or Pork Rinds – Use for an extra crunchy topping; pork rinds are a more budget-friendly alternative.
Extras
- Non-Stick Cooking Spray – Helps to prevent sticking during the baking process.
Step‑by‑Step Instructions for Keto Chicken Parmesan Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Keto Chicken Parmesan Casserole bakes evenly and reaches the perfect temperature for the cheese to melt beautifully. Setting the right temperature ahead of time is key to achieving that golden, bubbly top you desire.
Step 2: Sauté Garlic
In a large skillet, heat a splash of olive oil over medium heat. Once the oil is shimmering, add the minced garlic and sauté it for about 1 minute until it becomes fragrant and slightly golden. This step infuses the oil with rich aromas, setting a delicious foundation for the casserole.
Step 3: Combine Ingredients
Add the cubed rotisserie chicken, no-added-sugar marinara sauce, and Italian seasoning to the skillet with the sautéed garlic. Sprinkle in the almond flour to thicken the sauce, then stir everything together. Cook the mixture for about 5 minutes, stirring occasionally, until everything is well combined and heated through.
Step 4: Prepare Casserole Dish
While the filling is cooking, take a 9” x 13” casserole dish and coat it with non-stick cooking spray. This will prevent sticking and make cleanup a breeze. Once the dish is ready, pour the delicious chicken mixture into it, spreading it evenly across the bottom to form a hearty base for your casserole.
Step 5: Layer Toppings
Now it’s time to get cheesy! Evenly sprinkle grated parmesan cheese over the chicken mixture, followed by shredded mozzarella cheese for that melty goodness. Finish by adding a layer of finely crushed parmesan crisps or pork rinds on top to create a delightful crunchy topping that contrasts beautifully with the creamy filling.
Step 6: Bake
Carefully place the casserole into your preheated oven. Let it bake for 25-30 minutes, keeping an eye on it. You’ll know it’s done when the cheese is bubbly and golden brown, and the edges start to slightly crisp up. The mouthwatering aroma filling your kitchen will tell you that your Keto Chicken Parmesan Casserole is almost ready!
Step 7: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool for a few minutes. This resting time helps the casserole set, making it easier to serve. As the delicious flavors meld together, prepare to dish out generous portions of this comforting, cheesy delight!

Make Ahead Options
These Keto Chicken Parmesan Casserole make-ahead options are a lifesaver for busy weeknights! You can prepare the filling (chicken, marinara, and spices) up to 24 hours in advance by sautéing the ingredients, letting them cool, and refrigerating them in an airtight container. Additionally, you can mix the cheese topping and store it separately in the fridge. When you’re ready to bake, simply combine the chicken filling with the cheese mixture, assemble in your casserole dish, and bake as directed. This approach helps maintain the casserole’s quality, ensuring it’s just as delicious and cheesy when you serve it as it would be freshly made! Enjoy this time-saving dish that brings flavor and comfort in no time!

Keto Chicken Parmesan Casserole Recipe FAQs
What type of chicken should I use for the casserole?
Absolutely go for either cubed rotisserie chicken or boneless chicken breast! Using rotisserie chicken is a huge time-saver, allowing you to skip the cooking step entirely. If you opt for raw chicken breast, simply cook and cube it before mixing it with the other ingredients. The goal is to have tender chicken mixed with that savory marinara sauce.
How should I store leftovers from the casserole?
You can store your Keto Chicken Parmesan Casserole in an airtight container in the refrigerator for up to 3 days. Just make sure it’s completely cooled before sealing it up. This way, you can enjoy those cheesy goodness leftovers without compromising quality!
Can I freeze the casserole for later?
Yes! For long-term storage, you can freeze your casserole in a freezer-safe container for up to 2 months. Before freezing, wrap it tightly with plastic wrap or aluminum foil to prevent freezer burn. When you’re ready to enjoy it again, just thaw it in the refrigerator overnight and reheat in the oven at 350°F (175°C) for about 20-25 minutes until it’s heated through and bubbly.
What if I don’t have almond flour?
If almond flour is not available, you can omit it, although it aids in thickening the sauce. As a nut-free alternative, try using coconut flour, but remember that you’ll need less of it since it absorbs more moisture than almond flour. Start with just a couple of tablespoons and adjust the consistency from there!
Can I add vegetables to the casserole?
Very! Feel free to mix in sautéed vegetables like bell peppers, spinach, or zucchini for an extra nutritional boost and more flavor. Just make sure to sauté them first so they soften up and blend well into the casserole, complementing the chicken and cheese perfectly!
