Okay, so last Tuesday my crockpot officially became my best friend again. It was one of those days – you know the ones – where everything went sideways from the minute I rolled out of bed at 6:17 (not 6:15, not 6:20, but exactly 6:17 because apparently that’s my body’s magic wake-up number these days).
Emma called with yet ANOTHER crisis about her environmental science project (something about soil samples contaminated by her roommate’s kombucha experiment?), my thyroid meds made me feel like I was simultaneously exhausted and wired, and Charlie decided the corner of our new-ish Pottery Barn rug looked appetizing. James just stood there with his coffee mug like “what can ya do?” THANKS FOR NOTHING, HUSBAND.
But I digress… The point is, crockpot chicken spaghetti saved dinner AND my sanity. And prolly yours too, if you’re reading this!
What You Actually Need (Without the Fancy Stuff)
First things first – let’s talk ingredients, people. I’ve made this recipe so many times I could prolly do it blindfolded while simultaneously organizing my spice drawer (which, btw, I’ve been meaning to do since 2019… it’s fine).

The Must-Haves:
- Chicken breasts (boneless, skinless) – about 2 pounds-ish
- Spaghetti noodles – I use regular but whole wheat works if you’re being virtuous (I’m usually not)
- Cream of chicken soup – the canned stuff, don’t get all fancy on me
- Shredded cheese – whatever’s in your fridge, honestly… I’ve used everything from fancy gruyere left from a dinner party to the bagged mexican blend that was on sale
- Jar of pasta sauce – I’ve tried making my own and OMG NOT WORTH IT for this recipe
- Spices – garlic powder, Italian seasoning, salt, whatevs you like
- Veggies – onion, bell pepper, maybe some mushrooms if they’re not slimy yet in your crisper drawer
I forgot to mention I totes buy the pre-diced frozen onions now because I cannot STAND cutting onions. My eyes water so bad I look like I’ve been watching those Sarah McLachlan animal commercials. Worth the extra $1.79, I PROMISE.
The Kitchen Tools You’ll Need (If You Can Find Them)
So you’ll need…
- A crockpot (duh) – mine is ancient, like from my wedding registry in 2001 ancient
- Measuring cups – or just eyeball it like I do when James isn’t watching
- Cutting board that isn’t warped from that time you set a hot pan on it
- Knife that can actually cut things sometimes mine can’t
- Something to stir with (I use that silicone spoon-thing that doesn’t have a proper name)
Getting Everything Ready (Or What I Call The “Prep Scramble”)
Chopping Veggies Without Losing a Finger
Here’s where I confess something – I am THE WORST at cutting uniformly. My bell peppers end up looking like they were attacked by a tiny lawnmower. The pieces are all different sizes. James always points this out like I don’t KNOW this about myself already. It’s fine tho because they’re all gonna cook down anyway.
But if you’re normal, here’s what you should do:
- Wash everything first (I definitely sometimes skip this step when I’m in a rush, don’t tell the food police)
- Use a SHARP knife (not like mine that can barely cut butter)
- Cut big things into smaller things then into even smaller things
- Try not to cut yourself (I have a band-aid collection specifically for cooking accidents)
- If all else fails, food processor or pre-cut veggies from the store!
How I Season the Chicken (When I Remember To)
Let’s talk chicken seasoning. Here’s my not-very-scientific approach:
- Salt and pepper – I always add too much pepper then sneeze into my elbow while cooking. Sexy.
- Garlic powder – not garlic salt! Made that mistake and OMG SO SALTY we had to order pizza
- Italian seasoning – the one in my cabinet expired in 2021 but shhhhh
- Sometimes I throw in smoked paprika if I’m feeling fancy (rare)
One time I was on the phone with my sister and accidentally used cinnamon instead of paprika. DON’T DO THIS. Worst dinner ever. Ryan still brings it up at family gatherings like it’s the funniest thing that’s ever happened. Teenagers are so cruel.
Spaghetti – Not All Created Equal
I have Feelings about pasta. Strong ones.
Type | What I Think | When To Use It |
---|---|---|
Regular spaghetti | The classic, never disappoints | Always, but especially when cooking for picky eaters (like James) |
Whole wheat | Pretending to be healthy | When Emma comes over and judges my pantry contents |
Gluten-free | Tastes like sadness | Only if you actually have a gluten issue |
I once tried to use those zucchini noodles instead of pasta and Charlie wouldn’t even eat the leftovers. THAT BAD. Just use real pasta, life’s too short.
Actually Making The Darn Thing
Alright, now for the fun part… or the part where I usually spill something all over my kitchen. Either way.
How to Layer Everything (My Way, Not the Perfect Way)
This is not rocket science, people, but there is a method to my madness:
- First, spray your crockpot with non-stick spray because I HATE DOING DISHES
- Chicken goes on the bottom, seasoned with whatever you decided on
- Dump the chopped veggies on top
- Pour in your soup and sauce mixture
- DO NOT add the pasta yet! I learned this the hardway after making crunchy-yet-somehow-also-mushy pasta disaster of 2022
Timing Is… Well, It’s Something
I’m terrible with timing. TERRIBLE. I once left for a Target “quick trip” and came back 3 hours later to a very annoyed husband and overcooked dinner. But here’s what SHOULD happen:
- Low setting: 6-8 hours (this is for organized morning people, which I am not)
- High setting: 3-4 hours (this is for “oh crap it’s 2pm and I haven’t started dinner” people like me)
The chicken should be tender enough to shred with two forks. Not like last month when I undercooked it and James kept giving me that look. You know the one.
My Hard-Earned Tips From Many Failures
Listen, I’ve made this recipe probably 50+ times and I’ve messed it up in every possible way. Learn from my mistakes:
- Use a meat thermometer if you’re paranoid about undercooked chicken like me (165°F is the magic number)
- DON’T add the pasta until the last 30-40 minutes or you’ll have pasta mush
- Add most of the cheese during the last 15 minutes, but save some for right before serving
- Let it sit a few minutes before serving or you’ll burn your mouth (ask me how I know)
Oh and definitely don’t leave the wooden spoon in the crockpot for hours like I did once. It warped so bad it looked like Salvador Dali designed it.

Making It Your Own (Because Everyone’s a Food Critic)
The Spicy Version (That Made Ryan Drink a Gallon of Milk)
If you like things hot, add:
- Jalapeños – I leave the seeds in because I’m hardcore
- Red pepper flakes – a sprinkle or a handful, depending on your courage
- Hot sauce – whatever’s in your fridge (we have 7 different kinds because SOMEONE cough James cough collects them)
I made this version last Super Bowl and Ryan’s girlfriend thought she was impressing us by eating it without complaint. Found her in the kitchen later drinking milk straight from the carton. Respect.
The Extra Creamy Version (That’ll Make Your Arteries Cry)
For those special “my diet starts tomorrow” occasions:
- Add a block of cream cheese. Just do it.
- Extra cheese – like, way more than the recipe calls for
- Splash of heavy cream at the end
This version is what I make when I’m PMSing or when my mother-in-law is coming over so she can’t complain that I don’t feed her precious son properly.
The “I Should Eat More Veggies” Version (That No One Really Wants)
To pretend you’re being healthy:
- Double the bell peppers
- Add spinach (it wilts down to nothing anyway)
- Throw in some zucchini when nobody’s looking
- Mushrooms (the pre-sliced kind because life’s too short)
I tried to make this version “our regular” last January as part of my New Year’s resolution. By January 17th we were back to the extra creamy version. #noregrets
Serving It Up (The Part Where Everyone Actually Shows Up On Time)
Side Dishes That Don’t Require Much Effort
Because who has the energy for elaborate sides? Not this mama.
Would you like to save this?
- Garlic bread from the freezer section (the one in the foil is THE BEST)
- Bagged salad that you put in a nice bowl so it looks like you tried
- Those steamed veggie bags you microwave for 3 minutes
Last Thanksgiving I attempted homemade yeast rolls to go with dinner and they were so dense Ryan used one as a paperweight for his college application. TRUE STORY.
My Bread Recommendations (When I Actually Remember to Buy Some)
Bread makes everything better. Facts only:
- French bread – preferably slightly warm so butter melts on it
- Texas toast – the frozen garlic kind that’s like 500 calories a slice but SO WORTH IT
- Those refrigerated crescents that I can never roll properly so they look deformed
One time I forgot bread and James acted like I’d forgotten his birthday. THE DRAMA.
Storing What’s Left (If There Is Any)
How to Keep It Without Getting Food Poisoning
Safety first, or whatever:
- Let it cool a bit but not for hours (food safety police say 2 hours max)
- Use those containers with the lids that never match
- Refrigerate for up to 4 days
I have a special talent for forgetting exactly when I made something. Is this chicken spaghetti from Monday or last Friday? Who knows! It’s refrigerator roulette at the Hartwell house.
Reheating Without Ruining It
Leftovers can be tricky:
- Microwave: 1-2 minutes, stir, then another minute (my go-to lazy method)
- Stovetop: add a splash of something liquid-y (broth, water, milk) so it’s not dry
James INSISTS on using the stovetop for leftovers because “it tastes better that way” but then complains about the extra dishes. PICK A STRUGGLE, HONEY.

FAQs About Crockpot Chicken Spaghetti
What is the best way to ensure my crockpot chicken spaghetti is creamy?
To achieve maximum creaminess, use cream of chicken soup and plenty of cheese. For extra creaminess, add 2-3 tablespoons of sour cream or 4 ounces of cream cheese in the last 30 minutes of cooking. Stir well to incorporate.
Can I use frozen chicken for this easy crockpot chicken spaghetti recipe?
Yes, frozen chicken works in this recipe. Add approximately 1-2 hours to your cooking time if using frozen chicken. Always verify the internal temperature reaches 165°F before shredding.
What are some delicious variations I can try for this dish?
Popular variations include: adding diced jalapeños for a spicy kick, using Alfredo sauce instead of tomato sauce for a creamy white version, or adding extra vegetables like spinach, mushrooms, or zucchini for a more nutritious meal.
How do I store leftovers of crockpot chicken spaghetti?
Allow the dish to cool completely before transferring to airtight containers. Refrigerate for 3-4 days. For longer storage, freeze in portion-sized containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
What type of spaghetti works best for crockpot recipes?
Regular thickness spaghetti noodles work best in crockpot recipes. Thin spaghetti or angel hair pasta tends to overcook and become mushy. Whole wheat or gluten-free options also work well but may require slight adjustments to cooking time.
Can I make this recipe in advance?
Yes, you can prep all ingredients the day before and refrigerate them separately. Combine in the crockpot when ready to cook. Alternatively, fully cook the dish, refrigerate, and reheat when needed.
What’s an easy side dish to serve with my crockpot cheesy chicken spaghetti?
Garlic bread, a simple green salad, or steamed vegetables make excellent side dishes. The rich, creamy texture of the spaghetti pairs well with these lighter sides for a balanced meal.
How do I know when my crockpot chicken spaghetti is done?
Your dish is ready when the chicken easily shreds with two forks and the pasta is tender but not mushy. This typically takes 6-8 hours on low or 3-4 hours on high, with the pasta added during the final 30-40 minutes of cooking.
