Can I use chicken thighs instead of breast?

Yes — boneless thighs are more forgiving and add flavor. Sear the same way; they need an extra minute or two in the final simmer.

Why did my parmesan sauce turn grainy?

Pre-shredded cheese or too much heat. Grate from a block and stir the cheese in off the heat, a handful at a time.

What pasta shapes work for one-pot pasta?

Sturdy shapes like rigatoni, penne, cavatappi, and rotini. Long strands clump and delicate shapes overcook.

Can I make this lighter?

Use half-and-half stirred in fully off the heat, or cut the cream to half a cup and lean on the starchy broth for body.

One-pot garlic parmesan chicken pasta

By Ami · July 25, 2026 · ★★★★★ 4.9 from 27 reviews · Jump to Recipe · Print

This one-pot garlic parmesan chicken pasta is the easy dinner recipe I reach for when I want something creamy and restaurant-ish but refuse to wash three pans: golden seared chicken, pasta cooked right in the garlic parmesan sauce, 30 minutes, 46 grams of protein.

This creamy chicken pasta cooks in one pot and cleans up in one minute.

The pasta cooks in the sauce, not next to it. Simmering the noodles in garlicky broth means they drink up flavor instead of water, and the starch they release thickens the sauce for free — the same trick that makes our baked ziti taste like it simmered all day.
Searing the chicken first pays double. You get juicy, golden bites of chicken and a browned pan bottom that becomes the backbone of the sauce — the exact move behind our marry me chicken.
46g of protein in a bowl of creamy pasta. That's honest progress toward a daily target — run yours through the protein calculator — without a single sad chicken-and-rice container in sight.

Here's what you'll need.

Everyday ingredients, one non-negotiable: grate the parmesan yourself, because the pre-shredded kind is coated in starch and will fight you instead of melting.

Here's how it all comes together.

Step 1 — Season and sear the chicken

Toss the chicken pieces with salt, pepper, and Italian seasoning, then sear in butter and oil over medium-high until golden on two sides — about 5 minutes. Pull it out just shy of cooked through.

Step 2 — Bloom the garlic

Drop the heat to medium and cook the minced garlic in the leftover butter for 30–45 seconds, scraping up the browned chicken bits — fragrant, not browned, is the goal.

Step 3 — Add pasta and broth

Stir in the dry rigatoni so every piece gets glossed with garlic butter, then pour in the chicken broth. Bring it to a lively simmer.

Step 4 — Simmer until just al dente

Cover and simmer 10–11 minutes, stirring twice so nothing sticks. The pasta should be one minute shy of done with a little starchy broth still in the pot — that liquid is your sauce.

Step 5 — Stir in cream and parmesan

Off the heat, stir in the cream, then the parmesan a handful at a time. It melts into a glossy sauce in about a minute — off-heat is what keeps it silky instead of grainy.

Step 6 — Return the chicken and finish

Slide the chicken and its juices back in, simmer gently for 2 minutes to finish cooking, and shower with parsley, black pepper, and more parmesan.

Things I learned while testing this recipe.

Grate the parmesan yourself. Pre-shredded cheese is dusted with anti-caking starch and turns the sauce gritty — a block and a box grater fix every "my sauce broke" complaint I got.
Undercook the pasta by a minute. It keeps cooking in the hot sauce while you stir in cheese and chicken; cook it fully and it's soft by the table.
Don't dump the cheese in over the flame. High heat splits parmesan sauces. Off the heat, in handfuls, stirring between — glossy every time.
If the sauce tightens up, loosen with hot broth, a splash at a time. It reverses completely; extra cream just makes it heavy.

High-protein comfort food, no negotiation required.

46g protein per serving — the chicken and parmesan do it together, and the protein calculator will show you how far one bowl gets you.
Meal-prep friendly: it reheats into arguably better leftovers than night one — portion into containers with a splash of extra broth for the microwave.
Swap-friendly: rotisserie chicken (stir in at the end), chickpea pasta for extra protein, or half-and-half instead of cream all work without drama.

Here's what I'd serve with this.

Something crisp and spicy on the side — tonight's other new recipe, the air fryer bang bang salmon bites, makes a surprisingly great appetizer for this.
Charred peppers and onions from the sheet pan fajitas playbook to cut the richness.
A green salad, or steamed broccoli the way we do it for honey garlic chicken bowls.
If you're feeding a crowd alongside, the crockpot pot roast and this pasta cover every plate at the table.
Something sweet after — the 5-minute chocolate cottage cheese mousse keeps the protein theme going.

Just in case you have leftovers.

Storing: refrigerate in an airtight container up to 4 days. The sauce thickens as it chills — that's the starch and cheese doing their job, not a mistake. I don't recommend freezing; cream-and-parmesan sauces turn grainy on the way back.

Reheating: microwave at 70% power with a splash of broth or milk, stirring halfway — or rewarm gently in a skillet over medium-low. The sauce loosens right back to glossy.

One-pot garlic parmesan chicken pasta

★★★★★ 4.9 from 27 reviews — juicy seared chicken and rigatoni simmered in a creamy garlic parmesan sauce, all in one pot in 30 minutes, with 46g protein per serving.

Prep 10 min · Cook 20 min · Total 30 min · Serves 4 · Category: Easy Dinner · Cuisine: Italian-American

Ingredients

1.5 lb boneless skinless chicken breast, cut into 1-inch pieces
1 tsp kosher salt, ½ tsp black pepper, 1 tsp Italian seasoning
2 tbsp butter + 1 tbsp olive oil
6 garlic cloves, minced
12 oz rigatoni (or penne), uncooked
3½ cups low-sodium chicken broth
¾ cup heavy cream
1¼ cups freshly grated parmesan (about 3.5 oz), plus more to serve
2 tbsp chopped fresh parsley

Instructions

Sear. Season the chicken with salt, pepper, and Italian seasoning. Sear in butter and oil over medium-high until golden, about 5 minutes; remove just shy of cooked through.
Bloom. Reduce heat to medium; cook the garlic 30–45 seconds, scraping up the browned bits.
Combine. Stir in the dry pasta to coat, then add the broth and bring to a simmer.
Simmer. Cover and cook 10–11 minutes, stirring twice, until the pasta is just shy of al dente with a little starchy liquid left.
Sauce. Off the heat, stir in the cream, then the parmesan a handful at a time until glossy.
Finish. Return the chicken and juices; simmer gently 2 minutes. Top with parsley, black pepper, and extra parmesan.

Notes: Grate the parmesan from a block — pre-shredded won't melt smoothly. Chickpea pasta adds ~8g protein per serving. Sauce too thick? Loosen with hot broth a splash at a time.
