Ingredients

  

• Chicken: 1.5 pounds cooked chicken breast, shredded or diced
• High-protein pasta: 12 ounces (elbow, shells, or spirals)
• Cheddar cheese: 2 cups shredded, divided
• Low-fat mozzarella or Monterey Jack: 1 cup shredded
• Parmesan: 1/3 cup grated
• Greek yogurt (2% or nonfat): 1 cup
• Milk: 2 cups (2% or skim)
• Chicken broth: 1 cup, low sodium
• Butter or olive oil: 2 tablespoons
• Flour: 2 tablespoons (for the roux)
• Garlic: 2 cloves, minced (or 1 teaspoon garlic powder)
• Onion powder: 1 teaspoon
• Smoked paprika: 1/2 teaspoon
• Dry mustard: 1/2 teaspoon (optional, for classic mac flavor)
• Salt and pepper: to taste
• Panko or whole-wheat breadcrumbs: 1/2 cup (optional topping)
• Olive oil spray or a drizzle for the topping

Method

 

1. Heat the oven: Set to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
2. Cook the pasta: Boil in salted water until very al dente (1–2 minutes shy of package time). Drain and set aside.
3. Make the roux: In a large pot, melt butter over medium heat. Stir in flour and cook 1 minute, whisking until lightly foamy. Add minced garlic and cook 30 seconds.
4. Build the sauce: Gradually whisk in milk and chicken broth. Add onion powder, smoked paprika, dry mustard, salt, and pepper. Simmer 3–5 minutes, whisking, until thick enough to coat a spoon.
5. Stir in cheeses: Off the heat, add 1.5 cups cheddar, all the mozzarella, and Parmesan. Whisk until melted and smooth.
6. Add Greek yogurt: Whisk in yogurt until the sauce turns glossy and creamy. Taste and adjust seasoning.
7. Combine: Fold in cooked chicken and the drained pasta. The mixture should be saucy; it will thicken in the oven.
8. Assemble: Transfer to the baking dish. Sprinkle with remaining 1/2 cup cheddar. If using, top with panko and mist with olive oil spray.
9. Bake: Bake 18–22 minutes until bubbling at the edges. Broil 1–2 minutes to brown the top, watching closely.
10. Rest and serve: Let it sit 5–10 minutes so the sauce sets. Scoop and enjoy.

What Makes This Special

Save

This bake leans on simple ingredients and smart swaps. Using high-protein pasta and Greek yogurt bumps up the protein without sacrificing creaminess.

A quick stovetop sauce gets finished in the oven, so you still get those irresistible golden edges. It’s also meal-prep friendly, reheats well, and works with cooked rotisserie chicken when you need a shortcut. Best of all, it’s a flexible canvas—change the cheese, add veggies, and make it your own.

Keeping It Fresh

Store leftovers in airtight containers for up to 4 days in the fridge. Reheat covered in the oven at 325°F until warmed through, or microwave in short bursts with a splash of milk to keep it creamy. For freezing, cool completely, wrap tightly, and freeze for up to 2 months.

Thaw overnight in the fridge and reheat covered. If it looks a bit dry after thawing, stir in a spoonful of milk or yogurt before warming.

Health Benefits

• High protein: Chicken, Greek yogurt, and high-protein pasta deliver a balanced, filling meal that supports muscle maintenance.
• Smarter carbs: High-protein or legume-based pasta adds fiber and slows digestion, helping with steady energy.
• Lighter fats: Using 2% milk, part-skim cheeses, and yogurt gives a creamy texture with fewer saturated fats than heavy cream.
• Micronutrients: Cheese and yogurt provide calcium; chicken adds B vitamins; fortified pasta often includes iron.

Common Mistakes to Avoid

• Overcooking pasta: It will continue cooking in the oven. Keep it very al dente to prevent mushiness.
• Boiling the dairy: Too-high heat can cause grainy sauce.

  Simmer gently and add cheese off the heat.

• Under-seasoning: Pasta and chicken are mild. Salt the pasta water and taste the sauce before baking.
• Dry bake: If the mixture looks stiff before it hits the oven, add a splash of milk or broth. It should be a bit loose.
• Skipping rest time: Let it sit after baking so the sauce thickens and slices cleanly.

Recipe Variations

• Buffalo Style: Stir 2–3 tablespoons buffalo sauce into the cheese sauce and finish with blue cheese crumbles and green onions.
• Broccoli Cheddar: Fold in 2 cups steamed broccoli florets with the chicken.
• Southwest Twist: Add cumin, chili powder, black beans, and corn.

  Top with pepper jack.

• Turkey or Tuna: Swap chicken for ground turkey or canned tuna for a different protein profile.
• Extra Lean: Use nonfat Greek yogurt, reduce cheddar by 1/2 cup, and boost Parmesan for flavor with fewer calories.
• Gluten-Free: Choose gluten-free high-protein pasta and use a 1:1 gluten-free flour blend for the roux.
• Veggie-Loaded: Sauté mushrooms, bell peppers, or spinach and fold them into the mix.

FAQ

Can I use rotisserie chicken?

Yes. Shred the breast meat and remove the skin. It’s a great shortcut and adds flavor without extra effort.

What pasta shape works best?

Elbows, shells, or corkscrews grip the sauce well.

Choose a high-protein version so the dish stays sturdy and satisfying.

How do I keep the sauce from curdling?

Keep the heat moderate, add cheese off the burner, and whisk in Greek yogurt last. Avoid boiling once dairy is in the pot.

Can I make it ahead?

Assemble up to one day in advance, cover, and refrigerate. Add 5–10 extra minutes to the bake time and check for bubbling edges.

What cheeses melt best?

Cheddar for flavor, mozzarella or Monterey Jack for stretch, and Parmesan for umami.

Shred your own cheese for the smoothest melt.

How much protein is in a serving?

It varies by brands, but a generous serving often lands around 35–45 grams of protein when using high-protein pasta and Greek yogurt.

Can I skip the breadcrumb topping?

Absolutely. It’s optional. For crunch without crumbs, sprinkle extra Parmesan and broil briefly to crisp the surface.
