For the Base:

  • 12 oz spaghetti noodles
  • 2 cups diced or shredded cooked chicken (rotisserie works perfectly)
  • 1 can (10 oz) cream of chicken soup
  • 1 can (10 oz) diced tomatoes with green chiles (Rotel)
  • 8 oz Velveeta cheese, cubed
  • 1 cup shredded fiesta blend cheese
  • 1/2 cup chicken broth
  • 1 medium onion, diced
  • 1 bell pepper, diced
  • 2 cloves garlic, minced

For the Topping:

  • 1 cup shredded cheddar cheese
  • 1/2 cup panko breadcrumbs
  • 2 tablespoons butter, melted
  • 1/4 cup fresh parsley, chopped

Why These Ingredients Matter

The magic of this best chicken spaghetti recipe lies in the combination of Velveeta cheese sauce and cream of chicken soup, which creates that signature creamy base that coats every strand of pasta perfectly. Using rotisserie chicken saves time and adds incredible flavor, while the Rotel tomatoes and green chiles provide that subtle kick that makes this more than just basic pasta. The gooey melted cheddar topping creates that irresistible golden finish that makes this look as good as it tastes, similar to the cheese techniques I use in my cheesy chicken pasta.

Instructions for Making Cheesy Chicken Spaghetti

Step-by-Step Directions

Step 1: Preheat your oven to 350°F and grease a 9×13-inch baking dish. Cook spaghetti according to package directions until al dente, drain and set aside.

Step 2: In a large skillet, sauté diced onion and bell pepper until softened, about 5 minutes. Add minced garlic and cook for another minute until fragrant.

Step 3: Add cream of chicken soup, Rotel tomatoes, chicken broth, and cubed Velveeta to the skillet. Stir constantly over medium heat until the cheese melts and creates a smooth sauce.

Step 4: Add the cooked chicken and fiesta blend cheese, stirring until everything is well combined and the cheese is melted.

Step 5: Add the cooked spaghetti to the cheese mixture and toss until every strand is coated with that creamy chicken spaghetti casserole goodness.

Step 6: Transfer everything to your prepared baking dish. Top with shredded cheddar cheese and breadcrumbs mixed with melted butter.

Step 7: Bake for 25-30 minutes until bubbly and golden brown on top. Let cool for 5 minutes before serving, garnished with fresh parsley.

Hint: Don’t skip the resting time after baking! This allows the cheese sauce to set up properly so it doesn’t run all over the plate when you serve it.

Top Tip

The secret to perfect Cheesy Chicken Spaghetti is controlling the consistency of your cheese sauce. If it seems too thick, add a bit more chicken broth; if it’s too thin, simmer uncovered for a few minutes to reduce it.

Always melt the Velveeta over medium heat to prevent it from becoming grainy, and make sure your pasta is properly drained to avoid a watery casserole. For the most authentic southern comfort food pasta experience, let the flavors meld together for a few minutes before baking, just like the layering technique I use in my san giorgio lasagna recipe.

My Chicken Spaghetti Legacy

This recipe has been a lifesaver during some of our busiest family seasons. I remember the first time I made it was during a particularly hectic week when everyone had different schedules and I needed something that would reheat well for whoever came home hungry. Grandma watched me frantically trying to plan seven different meals and just shook her head with that knowing smile.

“Jazzy,” she said, pulling out her old casserole dish, “sometimes the best family meals are the ones that bring everyone together, no matter what time they get home.” She taught me that this simple chicken spaghetti recipe wasn’t just about feeding people – it was about creating a meal that felt like a warm hug after a long day.

The first time I served it, my family gathered around the table and we ended up having one of our best conversations in weeks. Now this baked cheesy chicken spaghetti has become our go-to for busy seasons, and I always think of Grandma’s wisdom about meals that bring people together every time that golden, bubbly dish comes out of the oven.

Grandma’s Secret for Cheesy Chicken Spaghetti

Grandma’s secret ingredient was a splash of heavy cream stirred into the cheese sauce just before adding the pasta. “It makes everything silky smooth, Jazzy,” she’d explain while pouring just a tablespoon or two. “Gives it that restaurant quality without any fuss.” That little bit of cream prevents the cheese from becoming stringy and creates the most luxurious texture.

Her other trick? She always saved a cup of the starchy pasta water before draining and added it back if the mixture seemed too thick. This helps everything bind together perfectly and creates that ideal saucy consistency that coats every noodle.

Instructions

  • In a large skillet, sauté the diced [onion] and [bell pepper] until they're soft and fragrant, about 5 minutes. There's no better smell in the kitchen! Add the minced [garlic] and cook for one more minute.
  • Now for the heart of the dish. To the skillet, add the [cream of chicken soup], [diced tomatoes with green chiles], [chicken broth], and the cubed [Velveeta cheese]. Stir this constantly over medium heat. Grandma always said to be patient here, letting the cheese melt slowly until the sauce is perfectly smooth.

Notes

  • Grandma’s Secrets: For the most luxurious, silky sauce, stir in a splash (1-2 tablespoons) of heavy cream just before adding the pasta. Her other trick was to save a cup of the starchy pasta water; if the sauce seems too thick, add a little pasta water to thin it out perfectly.
  • Make-Ahead Tip: You can assemble the entire casserole (without the breadcrumb topping) up to 24 hours in advance. Cover and refrigerate. Add the topping just before baking and add 10-15 minutes to the cook time.
  • Serving Suggestion: This is a wonderful one-dish meal, but it’s fantastic with a simple green salad and some garlic bread on the side.
  • Storage: Leftovers are a treasure! Store covered in the fridge for up to 4 days. The flavors get even better the next day.
