French Onion Dip Chicken Casserole Recipe

This creamy, savory French Onion Dip Chicken Casserole is made with tender shredded chicken, sour cream, and crispy fried onions, ready in 40 minutes. The sharp crunch of the golden onion topping gives way to a rich, bubbling filling underneath. I love making this when I need a comforting dinner with minimal prep.

Why This Classic Works

I used to overcomplicate weeknight dinners with too many steps and ingredients. Using a French onion soup mix stirred directly into sour cream creates an instant flavor base that tastes like it simmered for hours.

The surprise for me was how well the crispy fried onions hold their crunch after baking. It completely transforms a simple chicken bake into something memorable.

French Onion Dip Chicken Casserole Ingredients

• 16 oz rotini pasta, cooked and drained
• 3 cups shredded cooked chicken
• 16 oz sour cream
• 1 packet (1 oz) French onion soup mix
• 1/2 cup chicken broth
• 1 1/2 cups shredded mozzarella cheese, divided
• 1 cup crispy fried onions

How To Make French Onion Dip Chicken Casserole

1. Preheat and Prep: Preheat your oven to 375°F and lightly grease a 9×13 inch baking dish.
2. Mix the Sauce: In a large bowl, whisk together the sour cream, French onion soup mix, and chicken broth until smooth.
3. Combine Ingredients: Fold the cooked rotini, shredded chicken, and 1 cup of mozzarella cheese into the sour cream mixture until fully coated.
4. Transfer to Dish: Spread the chicken and pasta mixture evenly into the prepared baking dish.
5. Top and Bake: Sprinkle the remaining 1/2 cup of mozzarella and the crispy fried onions evenly over the top. Bake uncovered for 20-25 minutes until the edges are bubbling and golden.

Recipe Tips

• Use rotisserie chicken: It saves time and ensures the meat is tender and fully cooked.
• Cook pasta al dente: The noodles will absorb some of the sauce while baking, so keeping them firm prevents mushiness.
• Do not cover while baking: Leaving the dish uncovered ensures the fried onion topping stays perfectly crunchy.

What To Serve With French Onion Dip Chicken Casserole

Serve this hearty bake with a bright, crisp side dish to balance the richness. A simple green salad with a sharp vinaigrette or roasted green beans works perfectly.

How To Store

Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F to help the onions regain a bit of crispness, though they will soften slightly.

FAQs

Can I use a different type of pasta?

Yes, penne or macaroni are great alternatives that hold the creamy sauce well.

Can I make this ahead of time?

You can assemble the casserole a day in advance and store it covered in the fridge. Wait to add the crispy fried onions until right before baking.

What can I substitute for sour cream?

Plain Greek yogurt works well if you want a slightly tangier and lighter base.
