Ingredients You’ll Need
Here’s everything you’ll need for the classic version. Don’t worry—we’ll cover variations and substitutions afterward.
For the Pasta and Vegetables
- 8 oz pasta (penne, rotini, or farfalle work best)
- 2 cups broccoli florets (fresh or frozen, thawed and drained)
- 1 tablespoon olive oil
- Salt and black pepper, to taste
For the Chicken
- 3–4 boneless, skinless chicken breasts (about 1 pound total)
- 1 teaspoon Italian seasoning
- 1 tablespoon olive oil
- Salt and black pepper, to taste
For the Alfredo Sauce
- 3 cloves garlic, minced
- 1 cup heavy cream (or half-and-half for lighter version)
- 1 cup freshly grated Parmesan cheese
- ½ teaspoon Italian seasoning
- 1 tablespoon butter
- Pinch of nutmeg (optional but highly recommended)
- Salt and pepper, to taste
For the Topping
- ½ cup shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
- 2 tablespoons fresh parsley, chopped (optional for garnish)
Step-by-Step Instructions
Step 1: Prepare the Chicken
- Preheat oven to 375°F (190°C).
- Season chicken breasts with Italian seasoning, salt, and pepper.
- Heat olive oil in a skillet over medium-high heat.
- Cook chicken 5–6 minutes per side until golden brown and cooked through (165°F internal temperature).
- Remove from pan, let rest for 5 minutes, then slice into bite-sized pieces.
Step 2: Cook Pasta and Broccoli
- Bring a large pot of salted water to a boil.
- Cook pasta according to package directions, but stop 2 minutes before al dente.
- Add broccoli florets in the last 3 minutes of boiling.
- Drain, drizzle with a touch of olive oil, and set aside.
Step 3: Make the Alfredo Sauce
- In the same skillet used for chicken, melt butter over medium heat.
- Add garlic and sauté 30 seconds until fragrant.
- Stir in cream and bring to a gentle simmer.
- Gradually whisk in Parmesan until smooth and slightly thickened.
- Add Italian seasoning, nutmeg, salt, and pepper to taste.
- Simmer for 2–3 minutes, stirring occasionally.
Step 4: Assemble the Casserole
- In a large mixing bowl, combine pasta, broccoli, and chicken pieces.
- Pour Alfredo sauce over mixture and toss until evenly coated.
- Transfer to a greased 9×13-inch baking dish.
- Sprinkle mozzarella and Parmesan evenly over top.
Step 5: Bake and Serve
- Bake uncovered for 20–25 minutes, until cheese is melted and bubbly with golden spots.
- For an extra-crispy top, broil for the final 2 minutes (watch carefully).
- Remove from oven, let rest for 5 minutes.
- Garnish with parsley and serve hot.
Pro Tips for Success
- Cook pasta slightly underdone – It will finish cooking in the oven and prevent a mushy casserole.
- Use freshly grated cheese – Pre-shredded cheeses often contain starches that prevent smooth melting.
- Season in layers – Add a pinch of salt at every step (chicken, pasta water, sauce) for balanced flavor.
- Add nutmeg – Just a pinch enhances the creaminess of Alfredo sauce.
- Rest before serving – A short rest allows sauce to set and prevents watery servings.
Variations and Substitutions
One of the best things about this recipe is its flexibility. Here’s how you can adapt it to your family’s taste or dietary needs:
Healthier Version
- Use half-and-half instead of heavy cream.
- Swap some pasta for extra broccoli or cauliflower.
- Use part-skim mozzarella and reduce cheese slightly.
Gluten-Free
- Substitute pasta with your favorite gluten-free brand (brown rice, lentil, or chickpea pasta work well).
Low-Carb/Keto
- Replace pasta with zucchini noodles or shredded spaghetti squash.
- Use full-fat cream and cheese to keep it keto-friendly.
Extra Veggie Version
- Add spinach, mushrooms, peas, or bell peppers for more nutrition and color.
Flavor Variations
- Add a sprinkle of red pepper flakes for heat.
- Use Gruyere or Asiago for a gourmet twist.
- Swap chicken for shrimp for a seafood Alfredo bake.
Perfect Pairings
While this casserole can stand alone, here are some serving ideas to round out the meal:
- Garlic Bread or Breadsticks – Perfect for soaking up extra sauce.
- Crisp Green Salad – A fresh contrast with tangy vinaigrette.
- Roasted Vegetables – Asparagus, zucchini, or cherry tomatoes complement beautifully.
- White Wine – Pair with Pinot Grigio or Chardonnay for a restaurant-style touch.
