Ingredients You’ll Need

This Keto Chicken Parmesan Casserole comes together with just a handful of staple ingredients, each one playing a crucial role in bringing out the dish’s signature richness, creaminess, and crunch. Here’s what you’ll need—and why you’ll love every addition!

• Italian Seasoning: Infuses every layer with bold, herby goodness for that unmistakable Italian flavor.
• Minced Garlic: Just a touch brings warmth and a rich aroma to the casserole.
• Olive Oil: Sautéing the garlic in olive oil builds a savory base and helps infuse those flavors.
• Almond Flour: A keto-friendly thickener that adds subtle nuttiness—and helps bind everything together.
• Parmesan Cheese (Grated): Salty and sharp, this cheese amplifies that classic parmesan profile.
• Shredded Mozzarella Cheese: Melty, stretchy, and delicious: mozzarella ensures that gooey, cheesy topping everyone loves.
• Finely Crushed Parmesan Crisps (or Pork Rinds): For a delightfully crispy, golden lid on your casserole (and zero carbs!).
• Non-Stick Cooking Spray: This simple step guarantees quick cleanup and no sticking, so every scoop comes out picture-perfect.

How to Make Keto Chicken Parmesan Casserole

Step 1: Preheat Your Oven

Start by preheating your oven to 350 F. This ensures that your casserole will cook evenly and that irresistible cheese will become perfectly melted and bubbly while the flavors meld together.

Step 2: Sauté the Garlic

In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté it gently—just until fragrant. This quick step only takes about a minute but truly infuses the whole dish with that mouthwatering, homey aroma.

Step 3: Build the Flavor Base

Add the Italian seasoning, no added sugar marinara sauce, almond flour, and your cubed chicken to the skillet. Stir everything to combine, and let it cook together for about 5 minutes. The almond flour will add subtle body to the sauce, and the chicken will start soaking up all those herby, garlicky flavors.

Step 4: Assemble in the Casserole Dish

Grab a 9” x 13” casserole dish and give it a good coat of non-stick cooking spray. This helps with effortless serving later! Pour in your skillet mixture and smooth it out so every corner gets a bit of chicken and sauce.

Step 5: Layer On the Cheese (and Crispy Topping!)

This is the fun part: sprinkle on the parmesan cheese first, then blanket it with the mozzarella, and finish with a layer of finely crushed parmesan crisps (or pork rinds). This trio delivers that gooey, salty, crunchy topping synonymous with Chicken Parmesan—without the carbs, of course.

Step 6: Bake to Bubbly Perfection

Bake your Keto Chicken Parmesan Casserole for 25–30 minutes. You’ll know it’s ready when the cheese is melted and slightly golden in spots—the edges should be bubbling in the most tempting way.

Step 7: Let It Rest, Then Serve

Once your casserole is out of the oven, let it cool for a few minutes. This helps the cheese set just enough for perfect scooping and makes sure nobody burns their tongue diving in too quickly!

How to Serve Keto Chicken Parmesan Casserole

Garnishes

Brighten up your casserole with a shower of freshly chopped basil or flat-leaf parsley right before serving. A sprinkle of extra parmesan cheese on top brings even more savory richness, while red pepper flakes add a gentle kick if you’re a fan of a little heat.

Side Dishes

This casserole is hearty enough to be a meal on its own, but it pairs beautifully with a crisp green salad dressed in lemon vinaigrette, sautéed garlic green beans, or a side of zucchini noodles if you’re looking for an extra dose of veggies—while still keeping things delightfully low in carbs.

Creative Ways to Present

Try scooping your Keto Chicken Parmesan Casserole into individual ramekins for a dinner party-worthy presentation, or serve it family-style right from the bubbling baking dish for an ultra-comforting centerpiece at the table. For something really fun, use leftovers to stuff portobello mushrooms and bake until golden!

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer any leftover casserole to an airtight container and store it in the refrigerator for up to 4 days. The flavors continue to develop, making your next meal just as—if not more—delicious!

Freezing

This Keto Chicken Parmesan Casserole freezes wonderfully. Simply cool it down, portion it out, and store in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating to preserve the best texture.

Reheating

For best results, reheat your casserole in a 350 F oven, covered, until warmed through (about 15–20 minutes). You can also use the microwave for individual servings—just cover with a damp paper towel to keep things moist and cheesy.

FAQs

Can I use homemade marinara sauce?

Absolutely! If you have a batch of homemade no sugar added marinara on hand, it brings even more freshness and customization to your Keto Chicken Parmesan Casserole.

Is there a substitute for almond flour?

Yes! You can use coconut flour instead of almond flour, but reduce the amount to 1 tablespoon since coconut flour absorbs more moisture.

Can I make Keto Chicken Parmesan Casserole ahead of time?

Definitely! Prepare everything up to the point of baking, cover, and refrigerate for up to 24 hours. Just bake as directed when you’re ready for dinner.

What’s the best way to crush parmesan crisps or pork rinds?

Place them in a resealable bag and use a rolling pin—or even the bottom of a heavy glass—to crush until fine. This gives you that classic casserole crunch!

Can I add vegetables to this casserole?

Of course! Layer in some sautéed spinach, zucchini, or mushrooms for extra veggies while keeping your Keto Chicken Parmesan Casserole deliciously low-carb.
