3. Ingredients – Simple, Everyday Pantry Staples
You probably already have most of these ingredients in your kitchen. Here’s everything you’ll need:
Main Ingredients:
- 2 cups cooked chicken (shredded, diced, or rotisserie)
- 2 cups cooked pasta (penne, fusilli, or rigatoni)
- 1 medium sweet potato (peeled and diced into ½-inch cubes)
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
For the White Sauce:
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 cup milk (whole milk preferred)
- 1 teaspoon garlic powder
- Salt and freshly ground black pepper to taste
Extras:
- 1 tablespoon olive oil (for roasting sweet potatoes)
- Optional herbs: Thyme, basil, parsley (fresh or dried)
Ingredient Tip:
Try grating your own cheese for better meltability. Pre-shredded cheeses often contain anti-caking agents that can make sauces grainy.
4. Step-by-Step Instructions (with Pro Tips)
Let’s break it down into easy steps so you can master this dish from the first try.
🥄 Step 1: Roast the Sweet Potatoes
Preheat your oven to 400°F (200°C). Toss diced sweet potatoes with olive oil, a pinch of salt, and pepper. Spread them on a baking sheet and roast for 20–25 minutes until golden and fork-tender.
Pro Tip:
Roast until the edges caramelize. That slight char adds irresistible depth to your bake.
🧈 Step 2: Make the Creamy White Sauce
In a medium saucepan, melt butter over medium heat. Stir in flour and whisk constantly for about 1 minute to form a roux. Slowly pour in the milk while whisking to avoid lumps. Bring to a simmer and let the sauce thicken—about 3–5 minutes.
Add garlic powder, salt, and pepper to taste.
Pro Tip:
Don’t rush the sauce. A thick, smooth base is the secret to a luscious bake that doesn’t dry out.
🍗 Step 3: Assemble the Pasta Bake
In a large mixing bowl, combine the cooked pasta, shredded chicken, roasted sweet potatoes, and white sauce. Gently stir until every bite is coated.
Transfer the mixture into a greased 9×13-inch baking dish.
Sprinkle with mozzarella and parmesan cheese generously over the top.
Pro Tip:
Layer the mozzarella first, then Parmesan. This creates a gooey, melty middle and a crispy, cheesy top.
🔥 Step 4: Bake Until Golden
Bake uncovered at 375°F (190°C) for 20–25 minutes, or until bubbly and golden brown.
Let the dish sit for 5 minutes before serving to allow everything to set up.
Optional Garnish: Fresh herbs, a drizzle of olive oil, or a sprinkle of crushed red pepper.
5. Make-Ahead and Storage Tips
🕒 Make-Ahead Option:
- Assemble everything up to the baking stage.
- Cover tightly and refrigerate for up to 2 days.
- Let the dish sit at room temperature for 15–20 minutes before baking.
❄️ Freezer Friendly:
- Assemble the pasta bake in a freezer-safe dish.
- Wrap in foil and freeze for up to 2 months.
- Bake from frozen at 375°F for 45–55 minutes (cover for the first half).
♻️ Leftovers:

7. Common Mistakes and How to Avoid Them
✅ Overcooking Pasta Before Baking
Cook your pasta al dente. It will continue cooking in the oven.
✅ Skipping the Roux Step
Don’t skip whisking the flour and butter properly. A smooth roux is key to a creamy sauce.
✅ Not Roasting the Sweet Potatoes Enough
Undercooked potatoes make the texture grainy and bland. Let them roast until caramelized.
✅ Using Cold Ingredients for Assembly
Let ingredients come to room temp. This ensures even baking and prevents cold spots.
