Health Benefits
– High protein from chicken, cottage cheese, and Greek yogurt helps support muscle repair and keeps you full longer. – Lighter fat profile by skipping frying and using part-skim cheeses. – Better carbs if you choose high-protein or whole wheat pasta, which adds fiber to support digestion and steady energy.
Pitfalls to Watch Out For
– Overcooking pasta: Keep it slightly underdone so it doesn’t get mushy while baking. – Too much sauce or too little: Aim for creamy but not soupy. Start with 3 cups marinara and adjust. – Watery curds: Blend the cottage cheese smooth. If very wet, drain a bit before blending. – Under-seasoning: Taste the sauce and protein mixture; add salt, pepper, and herbs as needed.
Variations You Can Try
– Veggie boost: Fold in sautéed spinach, mushrooms, or zucchini. – Spicy kick: Add crushed Calabrian chiles or extra red pepper flakes. – Gluten-free: Use gluten-free high-protein pasta. – Lean and green: Swap half the pasta for roasted cauliflower florets. – Love protein-packed pastas and creamy bakes?

FAQ
Can I make this ahead?
Yes. Assemble up to the cheese topping, cover, and refrigerate for up to 24 hours. Add 5–10 extra minutes to the baking time if starting cold.
What’s the best pasta shape?
Short, ridged shapes like penne or rotini hold sauce well and bake evenly.
High-protein or whole wheat versions both work.
Can I use raw chicken?
Use cooked chicken for this recipe so the bake time focuses on melting and bubbling, not fully cooking the meat. Rotisserie chicken is an easy shortcut.
How do I make it extra crispy on top?
Broil for 1–2 minutes at the end and add a light sprinkle of panko mixed with Parmesan for a crisp finish.
What can I use instead of cottage cheese?
Part-skim ricotta works well. For extra protein, keep the Greek yogurt in the mix.
