- Shredded mozzarella cheese: Melts beautifully to create a gooey, cheesy topping.

How to Make Keto Chicken Parmesan Casserole Recipe
Step 1: Prepare Your Baking Dish
Start by preheating your oven to 375°F (190°C) and lightly greasing a 9×13-inch baking dish with olive oil. This little step ensures your casserole bakes evenly without sticking, and the olive oil adds a subtle richness to the base.
Step 2: Layer the Shredded Chicken
Spread the cooked shredded chicken breast evenly across the bottom of the prepared dish. This forms the hearty foundation of your casserole, packed with protein and ready to soak up all those wonderful seasonings.
Step 3: Season the Chicken
Sprinkle the garlic powder, Italian seasoning, and crushed red pepper flakes over your chicken layer. These spices build a mouthwatering aroma and depth of flavor that will shine through after baking.
Step 4: Add the Marinara Sauce
Pour the sugar-free marinara sauce evenly over the seasoned chicken. This tomato sauce brings a perfect balance of acidity and sweetness without any added sugars, maintaining the low-carb integrity of the dish.
Step 5: Top with Cheese
Generously sprinkle shredded mozzarella cheese over the marinara sauce, then add the grated Parmesan on top. The mozzarella melts into a luscious blanket while the Parmesan adds a slightly crispy, savory crust.
Step 6: Bake to Perfection
Place the casserole in the oven and bake uncovered for 20 to 25 minutes. Keep an eye out for bubbling cheese and a golden crust forming on top, signaling that it’s ready.
Step 7: Broil for Extra Golden Cheese
If you want a beautifully browned, slightly crisp cheese top, turn on your broiler for 2 to 3 minutes. Watch closely so it doesn’t burn, but this step adds that irresistible texture to the finish.
Step 8: Garnish and Serve
Finish your Keto Chicken Parmesan Casserole Recipe with a sprinkle of fresh basil leaves. The bright green herb not only enhances the dish visually but also brings a fresh, aromatic touch that complements the richness perfectly.
How to Serve Keto Chicken Parmesan Casserole Recipe
Garnishes
Fresh basil is the classic choice here—its peppery and sweet notes brighten up each bite. You can also add a sprinkle of extra grated Parmesan for a more intense cheesy hit or even a few cherry tomato halves for a burst of color and freshness.
Side Dishes
This casserole pairs wonderfully with a crisp green salad dressed in a lemon vinaigrette, helping to balance the rich cheese and chicken. For a heartier option, steamed broccoli or sautéed zucchini noodles are perfect low-carb companions that keep things light and nutritious.
Creative Ways to Present
Serve individual portions in small ramekins for a charming presentation at dinner parties. You can also layer the casserole over cauliflower rice for an all-in-one bowl or even stuff the mixture into bell peppers for a unique handheld delight.
Make Ahead and Storage
Storing Leftovers
Place any leftover Keto Chicken Parmesan Casserole Recipe in an airtight container and refrigerate for up to 4 days. This makes for an easy grab-and-go meal during busy days and keeps the flavors well-preserved.
Freezing
You can freeze the casserole in a tightly sealed container or heavy-duty freezer bag for up to 3 months. Thaw it overnight in the fridge before reheating to enjoy it at its best texture and taste.
Reheating
Reheat leftovers in the oven at 350°F (175°C) covered with foil to keep it moist, or microwave it on medium power in short intervals, stirring gently between to ensure even warming without drying out the cheese.
