High Protein Rotisserie Chicken Parmesan Casserole

Need a dinner that flexes serious protein and zero drama? This casserole delivers golden, cheesy comfort with juicy rotisserie chicken and saucy vibes in under an hour. Think chicken parm meets weeknight casserole, minus the oil splatter and plus leftovers that taste even better. Grab a fork—this one’s a keeper.

Why This Casserole Slaps (In a Cozy, Cheesy Way)

You get the classic chicken parm flavors—garlic, basil, melty mozzarella, and a crisp topping—without pounding cutlets or babysitting a skillet. We shortcut with rotisserie chicken and pump up protein using Greek yogurt and low-fat cottage cheese (trust me, it melts in and no one notices). It reheats like a champ and feeds a crew. Also, fewer dishes. You’re welcome.

What You’ll Need (And Smart Swaps)

Core Ingredients

• 3 cups shredded rotisserie chicken (skin removed)
• 2 cups marinara sauce (choose a no-sugar-added brand)
• 1 cup low-fat cottage cheese, blended smooth
• 1/2 cup plain nonfat Greek yogurt
• 1 cup part-skim shredded mozzarella
• 1/4 cup grated Parmesan, plus 2 tbsp for topping
• 1 large egg
• 1 cup cooked high-protein pasta (like chickpea or lentil), optional but great
• 1/2 tsp kosher salt, 1/2 tsp black pepper
• 1 tsp Italian seasoning
• 1/2 tsp garlic powder, 1/4 tsp crushed red pepper (optional heat)
• 1/4 cup whole-wheat panko or crushed high-protein crackers
• 1 tbsp olive oil or avocado oil spray
• Fresh basil, chopped (for finishing)

Easy Swaps (IMO, All Great)

• No cottage cheese? Use ricotta. Protein dips slightly, still delicious.
• Dairy-free? Swap dairy-free mozzarella and use an egg-free binder (2 tbsp aquafaba + 1 tsp cornstarch).
• Gluten-free? Choose GF panko or almond meal for the topping and GF pasta.
• No pasta mood? Skip it and add sautéed zucchini or roasted cauliflower for volume.

Step-By-Step Instructions

1. Preheat oven to 400°F (205°C). Lightly grease a 9×9 or 11×7 baking dish.
2. Blend the cottage cheese until smooth. In a large bowl, whisk the egg, then stir in Greek yogurt, blended cottage cheese, Parmesan, salt, pepper, Italian seasoning, garlic powder, and crushed red pepper.
3. Fold in the shredded rotisserie chicken, 1/2 cup mozzarella, and the cooked pasta (if using). Mix until evenly coated.
4. Spread 1/2 cup marinara on the bottom of the dish. Spoon in the chicken mixture and level it out. Top with remaining marinara, then sprinkle the remaining 1/2 cup mozzarella and 2 tbsp Parmesan.
5. Toss panko with a drizzle of olive oil (or spray to coat) and scatter over the top for that crispy chicken parm vibe.
6. Bake uncovered for 18–22 minutes until bubbling and the top turns golden. For extra crunch, broil 1–2 minutes—watch closely.
7. Rest 5–10 minutes so it sets. Shower with fresh basil and serve.

Flavor Boosters That Take It Next Level

• Garlic confit mashed into the yogurt mix = mellow, luxe flavor.
• Roasted cherry tomatoes on top before baking for juicy pops.
• Balsamic drizzle after baking for a sweet-tangy finish.
• Extra heat? Calabrian chili paste stirred into the sauce.

FAQ

Can I make this without the egg?

Yes. Mix 2 tablespoons aquafaba with 1 teaspoon cornstarch and whip lightly until foamy. Stir into the dairy mixture. You’ll keep the set and skip the egg.

What marinara sauce works best?

Pick a sauce with 140 mg sodium or less per 1/2 cup and no added sugar. A simple basil-garlic marinara keeps the chicken front and center and won’t drown the dish in salt.

How do I avoid a watery casserole?

Pat the chicken dry, don’t overload marinara, and let the casserole rest 5–10 minutes after baking. If using zucchini or spinach add-ins, sauté them first to drive off moisture.

Can I add veggies directly?

Absolutely. Roasted broccoli, sautéed mushrooms, or spinach fold in beautifully. Keep total add-ins to about 1–1.5 cups so the texture stays saucy, not soupy.

What’s the best cheese combo for max melt?

Part-skim mozzarella for stretch, a little whole-milk mozzarella for richness, and Parmesan for salty-nutty bite. If you love tang, add a few tablespoons of provolone or fontina.

Is this good for post-workout?

Totally. You get 36–40g protein per serving plus moderate carbs (more if you include pasta). Pair with a fast carb like fruit if you want an extra glycogen bump.
