One Pot Creamy Chicken Pasta – Ready in 25 Minutes!

A rich, comforting family dinner made entirely in one pot ready in just 25 minutes!

Some nights, the very last thing I want to deal with is a pile of dirty dishes.

That’s honestly how this recipe came to life. It was a hectic Tuesday evening. I was tired. I needed something warm, filling, and quick — with as little cleanup as possible.

One pot. One cleanup. Zero regrets.

What I keep coming back to with this One Pot Creamy Chicken Pasta is how deceptively simple it is. You’re using everyday pantry staples. But somehow, the end result tastes like something you’d order at a restaurant.

Here’s why. The marinara sauce and heavy cream come together to create this gorgeous, velvety pink sauce. It clings to every single pasta shell. Every. Single. One.

And speaking of shells — those aren’t a random choice. Medium shells are the MVP of this dish. Think of each little cup like a tiny bowl. It scoops up sauce, tender chicken, and rich Parmesan in every bite. That one small detail? It takes a good dinner to a great one.

Ingredient Notes

Here’s a quick look at what goes in and why each ingredient earns its place. Full quantities are in the recipe card below.

• Boneless skinless chicken breasts — The star. Cut them small and even so everything cooks at the same pace. Chicken thighs work just as well if that’s what’s in your fridge.
• Olive oil — Gets everything moving and builds that savory base. Any neutral cooking oil is a perfectly fine swap.
• Diced onions — Just half a cup. But don’t skip them. They add a quiet sweetness and depth that makes the sauce feel layered.
• Italian seasoning — One tablespoon of this blend pulls in oregano, basil, and thyme all at once. Dead simple, big flavor.
• Sea salt, garlic powder, and black pepper — The classic trio that seasons the chicken perfectly. Prefer fresh garlic? Go for it. Two minced cloves will do the job.
• Medium shell pasta (uncooked) — Goes in straight from the box, completely dry. It soaks up all that saucy goodness as it cooks.
• Marinara sauce — The tomato backbone of the whole dish. Use your favorite jar, or go homemade if you have some on hand.
• Water — Gives the pasta enough liquid to cook through without diluting the flavor.
• Heavy cream — Added near the end. This is the ingredient that takes the sauce from good to wow.
• Shredded Parmesan cheese — Salty, nutty, and creamy all at once. Freshly shredded is worth the extra thirty seconds — it melts so much smoother than the bagged stuff.
• Fresh parsley — Totally optional. But a handful of chopped parsley at the end adds a fresh, bright contrast to all that richness.

How to Make One Pot Creamy Chicken Pasta

This recipe moves fast. So before you turn on the stove, take two minutes to prep and measure everything out. Once you start cooking, you won’t want to stop and hunt for ingredients.

A good Dutch oven or a deep, heavy-bottomed pot makes this whole process feel effortless.

Step-by-Step Instructions

Step 1. Warm your Dutch oven or large pot over medium heat. Add the olive oil and diced onions. Cook for 2 to 3 minutes, stirring here and there, until the onions go soft and translucent.

Pro Tip: Don’t rush the onions. Letting them soften slowly pulls out their natural sweetness. That’s what builds the flavor base for the entire sauce.

Step 2. Add the chicken pieces. Sprinkle over the Italian seasoning, sea salt, garlic powder, and black pepper. Stir everything together and bump the heat up to medium-high. Cook, stirring often, until the chicken is no longer pink — about 6 to 8 minutes.

No need to cook it all the way through at this point. It’ll finish cooking with the pasta.

Step 3. Pour in the marinara sauce and water. Add the dry shell pasta straight from the box. Give it all a good, thorough stir. Place the lid on the pot and bring everything up to a gentle boil.

Step 4. Once it’s boiling, turn the heat back down to medium. Keep the lid on and stir every 3 to 4 minutes. This stops the pasta from settling and sticking to the bottom. After about 8 to 10 minutes, you’ll notice the shells starting to soften and soak up the sauce.

Pro Tip: Keep an eye on the liquid level. If the pot starts looking dry before the pasta is done, pour in a splash of water — about a quarter cup at a time. Don’t drown it, just enough to keep things moving.

Step 5. Take the lid off. Pour in the heavy cream and stir it gently into the tomato sauce. Watch what happens — the color shifts almost immediately to that beautiful creamy pink. Simmer uncovered on medium heat for another 3 to 5 minutes, until the sauce thickens just slightly and the pasta is cooked al dente.

Step 6. Pull the pot off the heat. Stir in the shredded Parmesan until it melts completely into the sauce. Taste it. Adjust the seasoning if anything feels off. Finish with a scatter of fresh chopped parsley if you’re using it, and serve immediately.

Tips for the Best Results

A few things I’ve learned from making this dish more times than I can count:

• Cut the chicken small and even — roughly ¾ inch to 1 inch pieces. Uneven cuts mean uneven cooking.
• Use a big pot. This recipe makes a lot of food. A 5-quart Dutch oven or larger is the sweet spot.
• Stir often once the pasta goes in. Shell pasta loves to sink and stick. A quick stir every few minutes makes all the difference.
• Don’t panic if the sauce looks thin after adding the cream. It will thicken as it simmers. And then it thickens a little more as it cools. Trust the process.
• Want it thicker? Stir in a bit more Parmesan at the end. Melt it fully and let the pasta sit for a minute or two.
• Freshly shredded Parmesan really does matter here. The pre-shredded bags are coated in anti-caking agents. That coating stops the cheese from melting smoothly — and you end up with a grainy sauce instead of a silky one.

Variations & Swaps

This recipe is flexible. Here’s how I’ve switched things up when needed:

• Pasta shape — Penne, rotini, or ziti all work well. Just avoid anything thin and delicate, like angel hair. It turns mushy fast in a one-pot method.
• Protein swap — Ground chicken or ground turkey both work if you prefer a different texture or just want to use what’s on hand.
• Sauce switch — A blended tomato basil sauce in place of marinara gives a slightly sweeter, more herb-forward flavor. Really good, actually.
• Veggie boost — Throw in a big handful of fresh spinach or some sliced mushrooms right when you add the cream. They cook down in minutes.
• Cream alternative — No heavy cream? Half-and-half works in a pinch. The sauce will be a little thinner, but still delicious.
• Pressure cooker version — Use the sauté function for the onions and chicken, then pressure cook everything together for 5 to 6 minutes. Fast and easy.

Serving, Storage & Frequently Asked Questions

Set this pot on the table and watch it disappear.

The smell alone — that creamy, tomato-y, Parmesan richness — pulls people into the kitchen before you even call them for dinner. Nobody walks away hungry. That I can promise you.

What to Serve With One Pot Creamy Chicken Pasta

This is a rich dish. Lighter sides are the way to go. My go-to pairings:

• Garlic bread or crusty Italian bread — perfect for scooping up every last bit of sauce
• A crisp green salad with a bright lemon vinaigrette — cuts right through the richness
• Roasted broccoli, asparagus, or green beans — simple, quick, and pairs beautifully
• A light vegetable soup as a starter — rounds out the meal without overdoing it

Storage & Reheating

Refrigerator

Let the pasta cool completely before putting it away. Store it in an airtight container and it’ll keep well in the fridge for 3 to 4 days.

One thing to expect — the sauce will thicken overnight. The pasta keeps absorbing liquid as it sits. That’s totally normal.

Reheating

Microwave individual portions with a small splash of water stirred in. Or warm it gently on the stovetop over low heat. Either way, add a little liquid as you go — water, chicken broth, or a tiny drizzle of cream. It brings the sauce right back to that silky consistency.

Pro Tip: Add your liquid gradually. Start with just 2 to 3 tablespoons. Stir well. Add more only if you need it. This is the difference between a restored creamy sauce and a watery mess.

Freezing

Good news for meal preppers. This pasta freezes well for up to 3 months. Let it cool fully first, then portion it into freezer-safe containers. Freeze flat if you can — it thaws more evenly.

When you’re ready to eat, thaw it overnight in the fridge and reheat as described above.

Ingredients

  

• 1 tbsp olive oil any neutral oil works too
• 1/2 cup diced onions yellow or white onion
• 1.5 lbs boneless skinless chicken breasts cut into small even pieces; thighs also work
• 1 tbsp Italian seasoning store-bought blend is perfect
• 1 tsp sea salt adjust to taste
• 1 tsp garlic powder or 2 fresh garlic cloves minced
• 1/2 tsp black pepper freshly cracked preferred
• 16 oz medium shell pasta uncooked; penne or rotini are great swaps
• 24 oz marinara sauce use your favorite jar or homemade
• 3 cups water helps cook the pasta in the pot
• 1/2 cup heavy cream adds richness and silkiness
• 1 cup shredded Parmesan cheese freshly grated melts best
• fresh parsley optional, chopped, for garnish

Instructions

 

• Warm your Dutch oven or large pot over medium heat. Add the olive oil and diced onions. Cook for 2 to 3 minutes, stirring occasionally, until the onions are soft and translucent.
• Add the chicken pieces. Sprinkle over the Italian seasoning, sea salt, garlic powder, and black pepper. Stir to combine and increase heat to medium-high. Cook, stirring often, until the chicken is no longer pink — about 6 to 8 minutes. No need to cook it all the way through at this point.
• Pour in the marinara sauce and water. Add the dry shell pasta straight from the box and stir everything together thoroughly. Place the lid on the pot and bring to a gentle boil.
• Once boiling, reduce heat to medium. Keep the lid on and stir every 3 to 4 minutes to prevent sticking. Cook for 8 to 10 minutes until the shells begin to soften and absorb the sauce. Add a splash of water (about ¼ cup at a time) if the pot looks too dry before the pasta is done.
• Remove the lid and pour in the heavy cream. Stir gently into the sauce — the color will shift to a beautiful creamy pink. Simmer uncovered on medium heat for 3 to 5 minutes, until the sauce thickens slightly and the pasta is cooked al dente.
• Remove the pot from heat. Stir in the shredded Parmesan until fully melted. Taste and adjust seasoning as needed. Garnish with fresh chopped parsley if desired and serve immediately.

Notes

Cut chicken into ¾ to 1 inch pieces for even cooking. Use a 5-quart Dutch oven or larger. Do not pre-cook the pasta — it goes in completely dry. Freshly shredded Parmesan melts much smoother than pre-bagged. If the sauce looks thin after adding cream, let it simmer a bit longer — it thickens as it cooks and continues to thicken as it cools. Leftovers keep well for 3 to 4 days in the fridge; add a splash of water or broth when reheating. Freezes well for up to 3 months.
