This chicken spaghetti with Rotel has been my dinner savior more times than I can remember since I found it last year. It's now my fallback when I want a hassle-free meal that still seems like I actually tried! That mix of the smooth sauce, soft chicken, and just the right amount of zing from the Rotel makes this the ultimate comfort dish that somehow tastes way better when you eat the leftovers.
My hubby's face brightens immediately when he spots me pulling meat off a store-bought chicken because he can guess what's coming! And my fussy nephew who claims he "can't stand casseroles" wolfed down two helpings of this.
Ingredients Rundown
- Store-bought roasted chicken: This time-saver changes everything. The ones from Costco offer the best bang for your buck, but any supermarket version works well too.
- Pasta noodles: Standard spaghetti does the trick, though I've thrown in thin spaghetti when that's all I had and it turned out fine.
- Rotel tomatoes: The key ingredient that gives this meal its character! I grab original, but go with mild for kids or folks who don't like heat.
- Chicken soup concentrate: Try to get the herbed version for extra taste. Don't worry about splurging on name brands here.
- Tangy cream: Adds that wonderful zingy smoothness that makes the sauce stand out.
- Shredded mix: The Mexican cheese blend melts wonderfully and tastes great. If you've got time, grate it yourself for better melting than the bagged stuff.
- Louisiana spice mix: This ties all flavors together! I prefer Tony Chachere's, but any similar seasoning works.

My Cooking Method
Time-Saving SetupI get my pasta water going first because that's the longest wait. While the water heats up, I pull the chicken apart and stir together the sauce mix, so everything's set when the noodles finish cooking.
Trick for Juicy ChickenMixing the pulled chicken with some broth and spices works wonders - it stops the meat from getting dry in the oven and spreads that cajun flavor all through it.
Getting the Sauce RightKeep the Rotel juice! That liquid packs tons of flavor into your sauce. I stir everything thoroughly to make sure the soup blends in completely before mixing with the pasta.
Aluminum Cover HackGiving your foil a quick shot of cooking spray before putting it on the dish is super important - or you'll lose half your cheese when you pull it off!
I originally whipped up this dish when my next-door neighbor had surgery and needed something easy that would heat up well. She loved it so much she asked me for the instructions before she'd even fully recovered!
What To Serve With It
This dish is filling enough on its own, but I often throw together a basic green salad with some tangy dressing to balance the richness. Toasted garlic bread works great too if you've got really hungry folks to feed. For big get-togethers, I sometimes split it between two smaller pans - making one spicy and one mild.
Customization Options
Toss in a can of drained corn for some sweetness and pop of color. Mix in cooked bell peppers and onions for extra veggies. Switch to pepper jack instead of Mexican blend if you want more kick. Use leftover holiday turkey when you're sick of turkey sandwiches.
Keeping It Fresh
This keeps amazingly in the freezer! I pack leftover portions into small containers for grab-and-go lunches. To warm from frozen, thaw in your fridge overnight then microwave with a splash of milk or broth to keep it creamy. For bigger portions, cover with foil and warm at 350°F until hot throughout.

Insider Tricks
- Snap the noodles in two before cooking so they're easier to mix and serve
- Save some pasta cooking water to thin the sauce if needed
- Use a clear dish so you can see when the edges turn golden and start bubbling
This chicken pasta dish has come to my rescue countless evenings when I'm beat but still crave something homemade and satisfying. There's something special about that blend of creamy sauce, tender noodles, moist chicken and that little kick from the Rotel that makes everyone think you worked much harder than you actually did!
