What Makes This Recipe Healthier?

Traditional chicken pasta bakes often rely on heavy cream, butter, and large amounts of full-fat cheese. While delicious, those ingredients can quickly increase calories, saturated fat, and sodium.

This healthier version makes a few smart substitutions without sacrificing flavor.

Greek Yogurt

Plain Greek yogurt creates a creamy sauce while adding protein and reducing fat compared to heavy cream.

Whole Wheat Pasta

Whole wheat pasta contains more fiber than regular pasta, helping you stay satisfied longer while supporting digestive health.

Lean Chicken Breast

Chicken breast is an excellent source of lean protein that helps maintain muscle while keeping calories lower than fattier cuts of meat.

Plenty of Vegetables

Broccoli, spinach, onions, mushrooms, and garlic boost the nutritional value while adding texture, flavor, vitamins, minerals, and antioxidants.

Reduced-Fat Cheese

Using reduced-fat mozzarella still provides that irresistible melted cheese topping while lowering saturated fat.

Step-by-Step Instructions

Step 1: Cook the Pasta

Bring a large pot of lightly salted water to a boil.

Cook the whole wheat penne until it’s just shy of fully cooked—about one to two minutes less than the package directions recommend.

The pasta will finish cooking in the oven, preventing it from becoming mushy.

Drain and set aside.

Step 2: Prepare the Vegetables

Heat a large skillet over medium heat.

Lightly coat with olive oil cooking spray or use one teaspoon of olive oil.

Add:

• Onion
• Mushrooms

Cook for about five minutes until softened.

Stir in the garlic and cook another minute until fragrant.

Add broccoli florets and cook for another three to four minutes.

Finally, stir in the spinach until wilted.

Your kitchen should already smell amazing.

Step 3: Prepare the Creamy Sauce

Lower the heat.

Mix together:

• Marinara sauce
• Greek yogurt
• Low-fat milk
• Italian seasoning
• Onion powder
• Paprika

Whisk until completely smooth.

Allow the sauce to gently warm but do not let it boil.

Step 4: Mix Everything Together

In a large bowl combine:

• Cooked pasta
• Chicken
• Vegetables
• Creamy sauce

Fold everything together until every piece of pasta is coated.

---

Step 5: Assemble the Casserole

Preheat the oven to 375°F (190°C).

Spray a 9×13-inch baking dish with nonstick cooking spray.

Spread the pasta mixture evenly into the baking dish.

Top with:

• Mozzarella
• Parmesan

Cover loosely with foil.

---

Step 6: Bake

Bake covered for 20 minutes.

Remove the foil.

Bake another 10 to 15 minutes until the cheese is bubbly and lightly browned.

Allow the casserole to rest for about 10 minutes before serving.
