One-Pot Creamy Chicken Spaghetti
Creamy chicken spaghetti that cooks in a single pot, no separate pasta water needed. The noodles soak up a garlic parmesan sauce as they simmer, so every bite is coated in flavour without piling up a mess of dishes.
It takes about 30 minutes and works with pantry staples you likely have on hand. You get tender chicken, a rich but not heavy cream sauce, and the kind of dinner that makes you glad you stayed home.
Why This One-Pot Pasta Is on Repeat
One pot to wash is its own reward. But the real pull is the method. The spaghetti cooks right in the broth and milk, absorbing all that savoury liquid instead of plain water. No bland noodles, no draining.
Chicken thighs stay juicy because they only get a quick sear. They finish cooking as the pasta simmers, so you never risk dry meat. The sauce feels lush without being heavy, thanks to cream cheese and parmesan instead of a pint of cream.
It rewards a little care, but it forgives you if things go sideways. Add more broth if the liquid cooks off too fast. Adjust salt at the end. That kind of low pressure is built for a school night.
Ingredients
- 1 lb boneless skinless chicken thighs: cut into bite sized pieces; thighs stay tender without brining
- 1 tbsp olive oil: for browning the chicken
- 1 tbsp unsalted butter: adds richness when you sauté the garlic
- 3 garlic cloves: minced, or use 1 tsp jarred minced garlic
- 1 ½ cups low sodium chicken broth: the cooking liquid; low sodium lets you control salt
- 1 cup whole milk: you can use 2%, but whole gives the best body
- 8 oz dry spaghetti: breaking it in half helps it fit the pan
- 4 oz cream cheese: softened, cut into a few cubes so it melts fast
- ½ cup grated parmesan: fresh grated melts smoother than pre shredded
- ¾ tsp salt: divided, plus more to taste
- ½ tsp black pepper
- 1 tsp dried Italian seasoning: or a mix of dried oregano and basil
- ¼ tsp red pepper flakes: optional, for a little warmth
- 2 tbsp chopped fresh parsley: for finishing
Variations / Substitutions
- Chicken breasts: use the same weight, but reduce sear time to about 2 minutes per side so they don’t dry out before joining the pasta.
- Add greens: stir in a couple handfuls of baby spinach during the last minute of cooking, letting it wilt in the residual heat.
- Sun dried tomatoes: toss in ¼ cup sliced oil packed sun dried tomatoes with the garlic for a tangy kick.
- Dairy free: swap the milk for unsweetened oat milk, the cream cheese for a thick cashew cream, and use a dairy free parmesan alternative.

How to Make One-Pot Creamy Chicken Spaghetti
Step 1: Season and Brown the Chicken
Pat the chicken pieces dry, then season them with ½ tsp salt, the black pepper, and the Italian seasoning. Heat the 1 tbsp olive oil in a large, deep pan or Dutch oven over medium high heat until it shimmers.
Add the chicken in a single layer (cook in two batches if needed). Sear without moving for about 4 minutes, until the underside is deeply golden. Flip and cook another 3 minutes. The chicken will not be cooked through, and that is exactly what you want. Transfer it to a plate and set aside.
Step 2: Sauté the Aromatics
Drop the heat to medium and add the 1 tbsp butter to the same pan. Once it melts, toss in the minced garlic and the red pepper flakes if using. Stir constantly for 1 minute, until the garlic smells toasty and fragrant.
Watch carefully here. Garlic goes from golden to bitter fast. If the pan seems too hot, slide it off the heat for a few seconds while you stir.
Step 3: Cook the Pasta in the Broth
Pour in the 1 ½ cups chicken broth and the 1 cup whole milk, scraping up any browned bits from the bottom of the pan. Add the 8 oz spaghetti, breaking the strands in half so they lie flat in the liquid.
Bring the pot to a boil over high heat, then immediately reduce to medium low. Give everything a good stir, cover with a lid, and cook for 10 minutes. Stir once or twice during that time to keep the pasta from clumping. The spaghetti should be al dente and most of the liquid absorbed, but the mixture will still look a bit saucy.
Step 4: Stir in the Creamy Finish
Remove the pan from the heat. Add the 4 oz cubed cream cheese and the ½ cup grated parmesan, stirring until both melt completely into a smooth sauce. Fold the seared chicken and any collected juices back in, then let the pot sit for 2 minutes so the sauce tightens and the chicken finishes cooking in the residual heat.
Taste and add the remaining ¼ tsp salt if needed. Spoon into bowls, scatter the chopped parsley over the top, and serve hot. The sauce will be glossy and thick, coating every strand.
Tips for the Best Creamy One-Pot Pasta
- Room temperature cream cheese melts lump free. Set it on the counter while you prep the other ingredients. If you forget, microwave it in a small bowl for 15 seconds.
- Stir a couple of times while the pasta simmers. This prevents the spaghetti from gluing itself to the pan bottom or tangling into a clump.
- Don’t walk away as the liquid reduces. Every stove and pan differs, and you might need to add a splash of broth if it seems too dry at the 8 minute mark.
- Parmesan rind trick: if you have a leftover rind, toss it in with the broth. It adds a salty depth you cannot get from grated cheese alone. Fish it out before serving.
Scale it up or down:
| Serves | Chicken (boneless thighs) | Dry Spaghetti | Chicken Broth | Milk | Cream Cheese |
|---|---|---|---|---|---|
| 2 | 8 oz | 4 oz | ¾ cup | ½ cup | 2 oz |
| 4 | 1 lb | 8 oz | 1 ½ cups | 1 cup | 4 oz |
| 6 | 1 ½ lb | 12 oz | 2 ¼ cups | 1 ½ cups | 6 oz |
Storing Leftovers
- Refrigerate: cool and pack into an airtight container. It keeps well for up to 3 days. The pasta will absorb more liquid as it sits, which is normal.
- Reheating: warm in a pan over low heat with a splash of milk or broth, stirring gently, until the sauce loosens back up. A microwave works too, in 30 second bursts with a stir between.
What To Serve With Creamy Chicken Spaghetti
A handful of simple sides round out the plate without extra pots. A peppery arugula salad dressed with lemon and olive oil cuts the richness. Garlic bread works because you’ll want something to swipe through the remaining sauce. Steamed broccoli tossed with a little salt and a squeeze of lemon adds a fresh crunch.
Frequently Asked Questions
Can I use pre cooked chicken instead of raw thighs?
Yes. Skip the searing step and stir 2 cups of chopped cooked chicken in at the very end, once the cream cheese has melted. Let it warm through for 2 minutes.
Why did my sauce turn grainy?
High heat likely broke the cream cheese or parmesan. Always remove the pan from the burner before stirring in the dairy, and keep the heat off until they melt. Low, gentle mixing fixes most graininess.
Can I use a different pasta shape?
You can, but adjust the cook time. Penne or fusilli will need about 12 to 13 minutes in the broth. Short shapes also trap more sauce in their ridges, which is never a bad thing.
Is this dish spicy?
Not at all. The red pepper flakes add a background warmth, not heat. Leave them out entirely if you prefer, or double them if you want a noticeable kick.
