  • Cream of Chicken & Cream of Mushroom Soups – These simple staples make the dish extra creamy.

How to Make Rotel Chicken Spaghetti

Step-by-Step Instructions

  1. Cook the Spaghetti – Start by boiling salted water and cooking your spaghetti until al dente. Drain and set aside.
  2. Sauté the Veggies – In the same pot, melt some butter and cook the bell peppers and onions until they soften.
  3. Mix Everything Together – Stir in the cream soups, Rotel tomatoes with green chilies, shredded chicken, 2.5 cups of cheddar cheese, and the cooked spaghetti. Mix it all up until it’s well combined.
  4. Assemble the Casserole – Transfer everything to a greased 13×9-inch casserole dish and sprinkle the remaining cheese on top.
  5. Bake Until Bubbly – Pop it in the oven at 325°F for about 15-20 minutes until the cheese is melted and the dish is heated through.
  6. Let It Rest & Enjoy! – Give it about 10 minutes to set before digging in.

Tips for the Best Chicken Spaghetti

  • Make it ahead of time – You can assemble everything, cover it, and refrigerate it until you’re ready to bake.
  • Use freshly shredded cheese – It melts better than the pre-packaged kind.
  • Want a little more spice? Add a dash of chili powder or some diced jalapeños.

What to Serve with Rotel Chicken Spaghetti

This dish is rich and creamy, so I like to keep the sides simple. Some delicious Texas Toast Garlic Bread and a mixed green salad or some roasted vegetables balance it out nicely. And if you’re in the mood for some classic Southern comfort switch out the garlic bread for some homemade cornbread!

Storing & Reheating

Got leftovers? Lucky you! This easy chicken spaghetti with Rotel reheats beautifully. Store it in an airtight container in the fridge for up to 3 days. When reheating, pop it in the microwave or warm it up in the oven at 300°F until heated through.

If you’re a fan of creamy, cheesy casseroles, this Rotel Chicken Spaghetti is a must-try. It’s simple, satisfying, and full of bold flavors. Whether you’re feeding a crowd or just want a cozy meal for the family, this dish never disappoints.

Try it out and let me know what you think! Do you like your chicken spaghetti extra cheesy or with a little more spice? I’d love to hear how you make it your own.
