How to Make Creamy Rotel Chicken Spaghetti Casserole

Follow these step-by-step instructions for a perfectly creamy, cheesy, baked masterpiece.

1. Prep the Pasta

Cook spaghetti until al dente. Drain and set aside. Avoid overcooking—the pasta will continue to soften in the oven.

2. Mix the Creamy Sauce

In a large mixing bowl, combine:

  • Cream of chicken soup
  • Drained Rotel
  • Any optional ingredients you’re using (cheese, seasonings, sour cream, etc.)

Stir until smooth and well-incorporated.

3. Add the Chicken and Pasta

Fold in the shredded chicken and cooked spaghetti. Toss gently until every strand is coated in creamy goodness.

If the mixture seems too thick, add a splash of chicken broth or milk.

4. Transfer to a Baking Dish

Grease a 9×13-inch casserole dish. Spread the mixture evenly.

Top with extra cheese for a golden, bubbly finish.

5. Bake Until Hot and Bubbly

Bake at 350°F (175°C) for 25–30 minutes, or until the edges are bubbling and the cheese is melted and slightly golden.

6. Garnish and Serve

Let the casserole rest for 5 minutes. Then top with fresh parsley, green onions, or a sprinkle of paprika.

Serve hot and enjoy creamy, cheesy perfection.

Expert Tips for the Best Rotel Chicken Spaghetti Casserole

Use Rotisserie Chicken

It saves time and offers tender, flavorful meat.

Drain the Rotel Well

Extra liquid thins the sauce—drain thoroughly for maximum creaminess.

Don’t Overcook the Pasta

Al dente pasta holds its texture through baking.

Boost the Creaminess

Add sour cream, cream cheese, or extra cheddar for richer texture.

Add Heat If You Like

Choose Hot Rotel or add jalapeños, cayenne, or chili flakes.
