 Ingredients

For the Pasta

• 20–25 jumbo pasta shells
• 1 tablespoon salt (for boiling water)

For the Filling

• 2 cups cooked chicken breast, finely chopped or shredded
• 2 cups broccoli florets, lightly steamed and chopped
• 1 cup shredded mozzarella cheese
• ½ cup grated Parmesan cheese
• 1 cup Alfredo sauce
• 2 cloves garlic, minced
• ½ teaspoon black pepper
• ½ teaspoon salt (or to taste)

For Homemade Alfredo Sauce (Optional but Recommended)

• 2 tablespoons butter
• 2 cloves garlic, minced
• 1 cup heavy cream
• 1 cup whole milk
• 1 cup freshly grated Parmesan cheese
• ¼ teaspoon black pepper
• Salt to taste

 Step-by-Step Instructions

Step 1: Cook the Pasta Shells

1. Bring a large pot of water to a rolling boil.
2. Add salt generously — this seasons the pasta from the inside.
3. Add jumbo shells and cook until al dente (usually 1–2 minutes less than package instructions).
4. Drain and rinse gently with cool water to stop cooking.
5. Lay shells flat on a tray so they don’t stick together.

Tip: Slightly undercooked shells are better because they’ll continue cooking in the oven.

Step 2: Prepare the Alfredo Sauce (If Making from Scratch)

1. In a medium saucepan, melt butter over medium heat.
2. Add minced garlic and sauté for about 30 seconds (don’t let it brown).
3. Pour in heavy cream and milk. Stir continuously.
4. Let simmer gently for 4–5 minutes until slightly thickened.
5. Add Parmesan cheese and whisk until smooth.
6. Season with salt and pepper.

The sauce should coat the back of a spoon. If it’s too thick, add a splash of milk.

Step 3: Make the Filling

In a large mixing bowl, combine:

• Cooked chicken
• Steamed broccoli
• Mozzarella cheese
• Parmesan cheese
• Garlic
• 1 cup Alfredo sauce
• Salt and pepper

Mix well until everything is evenly coated and creamy.

Optional additions:

• Red pepper flakes for heat
• A pinch of Italian seasoning
• A handful of spinach

Step 4: Assemble the Dish

1. Preheat oven to 350°F (180°C).
2. Spread 1 cup of Alfredo sauce on the bottom of a baking dish.
3. Fill each shell with 1–2 tablespoons of the chicken mixture.
4. Place stuffed shells seam-side up in the dish.
5. Pour remaining Alfredo sauce evenly over the top.
6. Sprinkle extra mozzarella and Parmesan over everything.

Step 5: Bake

• Cover with foil and bake for 20 minutes.
• Remove foil and bake an additional 10–15 minutes until bubbly and lightly golden.
• For a browned top, broil for 2–3 minutes at the end.

Let rest for 5 minutes before serving.

 Storage & Meal Prep
