The chicken adds heartiness, garlic adds depth, and the melted mozzarella creates that irresistible cheesy top layer.

How to Make Dump-and-Bake Chicken Alfredo Casserole

1. Preheat the oven

Preheat your oven to 425°F (220°C).

2. Assemble the casserole

In a large baking dish, add the uncooked rotini pasta, Alfredo sauce, chicken stock, cooked chicken, and minced garlic. Stir everything together until the pasta is evenly coated and submerged in the liquid.

Cover the dish tightly with aluminum foil.

3. First bake

Bake covered for 30 minutes.

After 30 minutes, remove the foil and give everything a good stir. At this stage, the pasta should be almost al dente — still slightly firm, with some liquid remaining in the dish. This is exactly what you want.

If the pasta is still very hard, cover and bake for an additional 5–10 minutes until it reaches that almost-done stage.

4. Add cheese

Sprinkle the shredded mozzarella evenly over the top.

5. Final bake

Return the casserole to the oven, uncovered, and bake for 5–10 minutes, until the cheese is melted and the pasta is perfectly tender (but not mushy).

6. Garnish & serve

Finish with freshly grated Parmesan and chopped herbs if desired. Serve hot and enjoy.

What to Serve With Chicken Alfredo Casserole

• Store in an airtight container in the fridge for up to 4 days

• Freezes well for up to 2 months

It reheats beautifully without drying out.

• Add broccoli or spinach for veggies

This base recipe is very forgiving and adaptable.

Frequently Asked Questions (FAQ)

Yes — bake at 200°C for about 10 minutes, flipping once.

Can I use a different pasta shape?

That depends on your fajita seasoning. Mild or spicy both work.

Why is there liquid left after the first bake?

Flour tortillas work best for folding and crisping.
