Ingredients You’ll Need

The magic of this Keto Chicken Parmesan Casserole lies in the simplicity and quality of its ingredients. Each one plays a crucial role—from the juicy chicken to the fragrant Italian seasoning and the melty cheeses that add irresistible richness and texture.

• 4 cups cubed rotisserie chicken: Use cooked, tender chicken for a quick, flavorful protein base.
• 3/4 cup no added sugar marinara sauce: Provides tangy tomato goodness without the extra carbs.
• 1 tbsp Italian seasoning: A perfect blend of herbs that bring authentic Italian flair.
• 2 garlic cloves (minced): Infuses the dish with a fragrant, savory aroma.
• 1 tbsp olive oil: Adds richness and helps sauté the garlic to golden perfection.
• 2 tbsp almond flour: A low-carb thickener that subtly enhances texture without overpowering flavors.
• 3/4 cup parmesan cheese (grated): Delivers a sharp, salty bite essential for that Parmesan character.
• 1 1/2 cups shredded mozzarella cheese: Melts into a gooey, creamy blanket over the casserole.
• 3/4 cup finely crushed parmesan crisps (or pork rinds): Creates a satisfyingly crunchy topping to contrast the creamy layers.
• Non-stick cooking spray: Ensures your casserole doesn’t stick and comes out cleanly after baking.

How to Make Keto Chicken Parmesan Casserole

Step 1: Prepare Your Oven and Skillet

Start by preheating your oven to 350 degrees Fahrenheit to ensure it reaches the perfect temperature for even baking. Meanwhile, grab a large skillet and heat the olive oil over medium heat. Add the minced garlic and sauté just until fragrant—about a minute—to release its wonderful aroma without burning it.

Step 2: Combine the Sauce and Chicken

Next, stir in the Italian seasoning, marinara sauce, almond flour, and your cubed chicken. Let everything mingle and cook together for around five minutes. This step lets the almond flour thicken the sauce slightly and allows the flavors to harmonize, guaranteeing each bite is packed with delicious seasoning and juicy chicken.

Step 3: Assemble the Casserole

Grab a 9” x 13” casserole dish and give it a good spray with non-stick cooking spray, so the casserole slides out effortlessly after baking. Pour the chicken and marinara mixture evenly into the dish, spreading it out to form a nice base for the cheeses.

Step 4: Layer the Cheesy Toppings

Now comes the indulgent part: sprinkle the grated parmesan cheese over the chicken, followed by a generous layer of shredded mozzarella. Finish off with the finely crushed parmesan crisps or pork rinds for that irresistible crunchy topping. This layering adds a combination of textures that will keep you coming back for more.

Step 5: Bake to Perfection

Place the casserole in your preheated oven and bake for 25 to 30 minutes. You’re aiming for a hot, bubbly dish with melted, golden cheese on top. When the timer goes off, take it out and let it cool for a few minutes so it can set slightly—this makes it easier to serve and enjoy every delicious forkful.

How to Serve Keto Chicken Parmesan Casserole

Garnishes

A sprinkle of fresh chopped basil or parsley adds a lovely pop of color and a fresh, herbaceous finish that complements the deep cheesy flavors perfectly. A little extra grated parmesan on top never hurts, especially if you love that savory umami hit!

Side Dishes

This casserole is a full meal on its own, but pairing it with a crisp green salad or some roasted low-carb vegetables like zucchini or asparagus can add a fresh contrast. Garlic butter sautéed spinach or a simple Caesar salad are also fabulous companions that keep things keto-friendly and balanced.

Creative Ways to Present

If you’re serving this at a casual dinner or gathering, consider scooping portions into individual ramekins or small cast iron skillets to wow your guests with personal servings. For a family-style dinner, serve it straight from the casserole dish and let everyone help themselves to the gooey, cheesy goodness.

Make Ahead and Storage

Storing Leftovers

Leftover Keto Chicken Parmesan Casserole keeps very well in the fridge for up to 4 days. Store it in an airtight container to preserve moisture and flavor. It tastes wonderful cold or reheated, making it a perfect option for meal prep or quick lunches.

Freezing

You can freeze this casserole for up to 3 months. Just cover it tightly with foil or plastic wrap and place it in a freezer-safe container. When you’re ready to enjoy it, thaw overnight in the refrigerator before reheating to maintain the best texture and flavor.

Reheating

To reheat, pop individual servings in the microwave for a couple of minutes or warm the whole casserole in a 350-degree oven until heated through and the cheese is melty again. Adding a few extra parmesan crisps on top before reheating can revive the crunchy topping beautifully.

FAQs

Can I use fresh chicken instead of rotisserie chicken?

Absolutely! You can cook and cube fresh chicken breasts before assembling the casserole. Rotisserie chicken adds convenience and extra flavor, but fresh chicken works just as well when cooked thoroughly.

Is this casserole suitable for strict keto diets?

Yes, it uses low-carb ingredients like almond flour instead of breadcrumbs and no sugar-added marinara, making it perfect for keto eating plans without sacrificing deliciousness.

Can I substitute the almond flour with another low-carb flour?

You can try coconut flour, but since it absorbs liquid differently, use less and be cautious to maintain the right sauce consistency. Almond flour tends to be the most reliable for this recipe.

What if I don’t have parmesan crisps or pork rinds?

You can skip the crunchy topping or make your own by baking some parmesan cheese in small piles until crispy. It adds great texture but isn’t absolutely necessary.

Can this casserole be made dairy-free?

It would be challenging since cheese is central to the flavor and texture. However, using dairy-free cheese alternatives might work with some adjustment, though the final taste and texture will differ.
