This chicken spaghetti with Rotel has become my family's favorite meal since I stumbled across it last year. It's now my trusty backup when I want a hassle-free dinner that looks impressive! The blend of smooth sauce, soft chicken, and that little kick from the Rotel makes for a warm, comforting dish that somehow tastes even yummier when you heat it up the day after.
My partner grins from ear to ear whenever he spots me pulling meat off a rotisserie chicken because he knows what's coming! And even my fussy nephew who claims he "can't stand casseroles" wolfed down two big helpings of this.
Ingredients Needed
- Rotisserie chicken: The ultimate time-saver. I find Costco offers the best deal, but any grocery store version works great.
- Spaghetti: Standard spaghetti does the job perfectly, though I've successfully used the thin kind when that's all I had.
- Rotel tomatoes: The key ingredient that gives this meal its character! Standard works for me, but go with mild if you're feeding kids or folks who don't like heat.
- Cream of chicken soup: Try to grab the herbed version for extra taste. Don't worry about splurging - store brands work just as well.
- Sour cream: Creates that wonderful creamy tang that makes the sauce so special.
- Cheese: Mexican blend melts beautifully and adds great flavor. If you can, shred it yourself for better melting than the pre-packaged stuff.
- Cajun seasoning: The magic touch that pulls everything together! Tony Chachere's is my go-to, but any type will do.

Cooking Instructions
Getting ReadyI always put the pasta water on to boil first because that takes the longest. While I wait, I pull apart the chicken and blend the sauce ingredients so everything's ready when the pasta finishes cooking.
Juicy Chicken TrickMixing the pulled chicken with a bit of chicken broth and spices works wonders - it keeps the meat juicy during baking and spreads that cajun flavor into every bite.
Getting The Sauce RightKeep all the liquid from the Rotel! That juice packs tons of flavor for the sauce. I mix everything thoroughly to get rid of any soup lumps before combining with the pasta.
Handy Foil TipDon't forget to spray cooking oil on the foil before covering your casserole - this is super important or you'll lose half your cheese when you pull off the foil!
I first whipped this up when my next-door neighbor was recovering from surgery and I needed something easy to drop off that would warm up nicely. She loved it so much she asked me for the instructions before she was even back on her feet!
Tasty Pairings
This dish is filling enough on its own, but I often throw together a basic green salad with vinaigrette to balance out the richness. Garlic bread works great too if you've got really hungry mouths to feed. For bigger get-togethers, I sometimes split it between two smaller dishes - one spicy and one mild.
Custom Tweaks
Toss in a can of drained corn for a pop of sweetness and color. Mix in some cooked bell peppers and onions to sneak in extra veggies. Switch to pepper jack cheese instead of Mexican blend if you want more heat. Use leftover holiday turkey when you're sick of turkey sandwiches.
Saving Leftovers
This dish freezes wonderfully! I split leftovers into single-serving containers for grab-and-go lunches. To heat from frozen, let it thaw in the fridge overnight then microwave with a splash of milk or chicken broth to keep it creamy. For bigger portions, cover with foil and bake at 350°F until hot throughout.

Smart Suggestions
- Snap the spaghetti in half before boiling for easier mixing and serving
- Save some pasta cooking water to thin the sauce if it gets too thick
- Use a clear baking dish so you can tell when the edges turn golden and bubbly
This chicken spaghetti dish has come to my rescue countless times when I'm too tired to cook but still want something homemade and satisfying. There's just something special about the mix of creamy sauce, tender pasta, juicy chicken and that slight heat from the Rotel that makes everyone think you spent hours in the kitchen when you really didn't!

- → What's the best way to warm up leftovers?

Steps
Set oven to 375°F to preheat. Get a big pot of water boiling, toss in the spaghetti, and cook it following the instructions on the box.
Remove the chicken from the bones and throw it in a big bowl. Add ¼ cup chicken broth to moisten it and sprinkle about 2 tablespoons of cajun spices over it. Make sure it’s all mixed and coated evenly.
In a separate bowl, throw together sour cream, cream of chicken soup, garlic, Rotel (don’t drain it), 1 tablespoon of cajun seasoning, pepper, seasoned salt, and red pepper flakes. Whisk until smooth.
Take the warmed-up ¾ cup chicken stock and stir it slowly into the sauce blend you just made.
Grab a 9×13 baking dish and mix in your cooked spaghetti, spiced chicken, sauce mixture, and half the cheese. Use kitchen tongs to make sure everything is evenly spread out.
Spread the leftover cheese on top. Sprinkle with parsley. Put a layer of foil on top, sprayed with nonstick oil first. Bake for 25 minutes, uncover, then bake 10 more minutes until bubbly and golden at the edges.
Notes
- Store-bought cajun spice mix is fine if you don’t make your own.
- Heat leftovers with small splashes of chicken broth to bring the pasta back to life.
- Super handy for making ahead when the week’s packed.
