Time to bring everything together! This step-by-step guide walks you through building layers of flavor, from sautéing the veggies to baking the cheesy finale. Follow each instruction carefully, and you’ll end up with a bubbly, golden-brown casserole that’s impossible to resist.
1. Preheat your oven to 350°F (175°C).
2. In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté until translucent, about 5 minutes.

4. Stir in the broccoli florets and cook for an additional 2–3 minutes until tender but still crisp.
5. In a large mixing bowl, combine the cooked and shredded chicken, cooked pasta, sautéed vegetables, sour cream, chicken broth, dried thyme, dried basil, paprika, salt, and pepper. Mix well until everything is evenly coated.
6. Transfer the chicken mixture to a greased 9×13-inch baking dish, spreading it out evenly.
7. Sprinkle the shredded cheddar cheese over the top of the casserole.
8. Sprinkle grated Parmesan cheese on top for added flavor and texture.
9. Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes.
10. After 25 minutes, remove the foil and bake for an additional 15–20 minutes, or until the cheese is bubbly and golden brown.
11. Once done, remove from the oven and let it sit for about 5 minutes before serving.

Frequently Asked Questions
Got questions about this casserole? Here are some quick answers:
- How long does it take to prepare and bake this casserole from start to finish?
Total time is about 25 minutes prep plus 40–45 minutes baking. You’ll spend roughly 10–15 minutes shredding chicken, chopping vegetables, and mixing ingredients, then 25 minutes covered in the oven and an additional 15–20 minutes uncovered until the cheese is golden and bubbly.
- Can I assemble the casserole ahead of time and refrigerate it?
Yes. Prepare the entire casserole, cover it tightly with foil or plastic wrap, and store it in the refrigerator for up to 24 hours. When ready to bake, let it sit at room temperature for 15–20 minutes, then bake at 350°F for the same 25 minutes covered and 15–20 minutes uncovered. You may need to add a few extra minutes if the casserole is very cold.
- What substitutions can I make for dairy or vegetables?
You can swap sour cream for full-fat Greek yogurt or a mixture of light cream cheese and milk for a similar tang. If you need a dairy-free version, use a nondairy yogurt and plant-based cheese. For vegetables, you can replace broccoli with spinach, bell peppers, zucchini, or peas; just sauté them until tender-crisp before mixing.
- Can I freeze this casserole, and how should I reheat it?
Yes, freeze the unbaked casserole in an airtight container or wrapped tightly in foil for up to 2 months. Thaw overnight in the fridge, then bake at 350°F for 30–35 minutes covered, remove the foil, and bake another 15–20 minutes until heated through and cheese is golden. Leftover baked portions reheat well in a 350°F oven for 15–20 minutes or in the microwave until warm.
- How can I make the topping extra crispy or golden?
For a crispier top, sprinkle ¼–½ cup of breadcrumbs mixed with a tablespoon of melted butter over the Parmesan before baking. After the covered bake time, remove the foil and broil on high for 2–3 minutes, watching closely so the cheese crisp up without burning.
- Is it possible to reduce the fat content without losing flavor?
Yes. Use low-fat sour cream or Greek yogurt and opt for reduced-fat cheddar. You can also cut back to ½ cup of cheddar and rely more on the Parmesan topping for flavor. Increasing the ratio of vegetables to pasta and chicken will help stretch the dish while keeping calories lower.
- Can I use gluten-free pasta, and does it affect the bake time?
Absolutely. Cook your favorite gluten-free penne or rotini according to package directions, drain well, and proceed as instructed. Gluten-free pasta can sometimes release more starch, so rinse it briefly under cold water after cooking to prevent the casserole from becoming gummy. Bake times remain the same.
