Ingredients Overview
Pasta
Short shapes like:
Penne
Rotini
Fusilli
Ziti
They hold onto the creamy sauce and bake up beautifully. Cook just until al dente since they’ll finish in the oven.
Chicken
Use cooked, shredded or diced boneless chicken breast or thighs. Rotisserie chicken is a great shortcut. Grilled, baked, or leftover chicken all work well.
Broccoli
Fresh or frozen broccoli florets bring texture and color. Steam or blanch before adding to the mix so they stay vibrant and tender.
Pesto
Basil pesto brings bold herby flavor and richness. Store-bought or homemade both work. Use refrigerated pesto for better texture and flavor than jarred shelf-stable kinds.
Cream Sauce
The creamy base blends:
Heavy cream or half-and-half
Garlic
Parmesan cheese
Optional: a bit of cream cheese for extra richness
The pesto gets stirred into this warm sauce to coat the pasta evenly.
Mozzarella or Italian Cheese Blend
Melty mozzarella creates that irresistible cheese pull. Mix with a bit of Parmesan for extra sharpness.
Seasonings
Keep it simple:
Salt & pepper
Garlic or onion powder
Red pepper flakes (optional for heat)
Step-by-Step Instructions
1. Cook Pasta and Broccoli
Bring a large pot of salted water to a boil.
Add pasta and cook for 2 minutes less than package directions (al dente).
Add broccoli florets during the last 2 minutes of cooking.
Drain well and set aside.
2. Make the Creamy Pesto Sauce
In a large skillet or saucepan:
Melt 2 tbsp butter over medium heat.
Add 2 cloves minced garlic and sauté for 1 minute.
Pour in 1½ cups heavy cream (or half-and-half).
Simmer for 3–4 minutes until slightly thickened.
Stir in ½ cup grated Parmesan and ½ cup pesto.
Add salt, pepper, and a pinch of red pepper flakes if desired.
Add 2–3 tbsp cream cheese for a richer texture (optional).
3. Combine Everything
In a large mixing bowl or the pot used for pasta, combine:
Cooked pasta and broccoli
Diced or shredded cooked chicken (2–3 cups)
Creamy pesto sauce
Toss gently until everything is coated.
4. Assemble the Bake
Pour the mixture into a greased 9×13″ baking dish.
Top with 1½–2 cups shredded mozzarella cheese (plus extra Parmesan if you like).
5. Bake
Bake uncovered at 375°F (190°C) for 20–25 minutes, or until bubbly and golden on top.
Broil for 2–3 minutes at the end for extra browning.
6. Cool & Serve
Let sit 5 minutes before serving to help it set. Garnish with fresh basil or parsley if desired.
Tips, Variations & Substitutions
Tips for Success
Don’t overcook pasta—it will finish cooking in the oven.
If sauce seems too thick, thin with a splash of pasta water or milk.
Mix cheeses (mozzarella, fontina, provolone) for more flavor.
Variations
Low Carb: Use cooked cauliflower or zucchini noodles instead of pasta.
Meat-Free: Omit chicken and add mushrooms or white beans.
Spicy Kick: Use spicy pesto or add a pinch of cayenne.
More Veggies: Stir in spinach, roasted red peppers, or peas.
Ingredient Swaps
No cream? Use whole milk with a little flour or cornstarch to thicken.
No pesto? Blend basil, spinach, garlic, olive oil, and Parmesan for a DIY version.
Dairy-free? Use cashew cream and vegan cheese alternatives.

FAQ: Creamy Pesto Chicken & Broccoli Pasta Bake
1. Can I use rotisserie chicken?
Absolutely! Shredded rotisserie chicken is perfect and saves prep time.

Yes—penne, rotini, shells, or any short pasta works. Gluten-free pasta can also be used, but avoid overcooking before baking.

5. How do I store and reheat leftovers?
Store in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven with a splash of milk or cream to loosen the sauce.
