Healthy Garlic Parmesan Chicken Pasta – 30-Minute One-Pan

Healthy Garlic Parmesan Chicken Pasta solves a specific problem: you want a creamy pasta dinner on a Tuesday night without 600 calories and a sink full of pans. This version lands at roughly 428 calories and 34 grams of protein per serving, and it cooks in one skillet from raw chicken to finished sauce.

The mechanics matter here. Pasta releases starch as it boils, and that starch is what thickens the sauce when the pasta finishes cooking directly in the skillet with broth and milk. Skip that step and you get a watery sauce that slides off the noodles.

I tested this at 6 servings using 12 ounces of pasta, not a full pound. That ratio gives you a sauce-to-noodle balance that actually coats every strand instead of pooling at the bottom of the pan.

About the Ingredients

12 oz (340g) short pasta, such as penne or rigatoni

Short shapes with ridges hold the Parmesan sauce better than long noodles. If you only have spaghetti, break it in half and add 1/4 cup extra broth, since it packs tighter in the pan.

1.5 lb (680g) boneless, skinless chicken breast, cut into 1-inch pieces

Cut against the grain into even 1-inch cubes so they hit 165F (74C) at the same time. Boneless thighs work as a swap but need 2 extra minutes of searing and add about 40 calories per serving.

2 tbsp olive oil

Regular olive oil, not extra virgin, is the right call for a 400F (204C) sear because it has a higher smoke point. Avocado oil is a direct substitute if you have it.

6 cloves garlic, minced (about 2 tbsp)

Fresh cloves only here; jarred garlic tastes flat and burns faster. If garlic is too sharp for you, use 4 cloves and add 1/4 tsp garlic powder at the end.

2 cups (480ml) low-sodium chicken broth

Low-sodium matters because the Parmesan adds 1,000mg+ of sodium on its own. Vegetable broth works for a meatless-adjacent version, though the flavor gets noticeably sweeter.

1.5 cups (360ml) 2% milk

2% gives you creaminess without the 400-calorie hit of heavy cream. Whole milk is a fine swap; skim milk tends to break when it simmers, so avoid it.

1 cup (100g) grated Parmesan, plus more for serving

Buy a block and grate it yourself; pre-shredded Parmesan is coated in cellulose and clumps instead of melting. Pecorino Romano is a sharper, saltier substitute, so cut it to 3/4 cup.

1 tsp Italian seasoning

A dried blend of oregano, basil, and thyme. If yours is over a year old, add 1/2 tsp more, because dried herbs lose potency fast.

1/2 tsp red pepper flakes

Optional but recommended; it cuts through the dairy fat. Aleppo pepper is a milder swap if you are feeding kids.

1/2 tsp kosher salt and 1/4 tsp black pepper

Kosher salt, not table salt, for even seasoning on the chicken. If using table salt, halve the amount.

2 cups (60g) baby spinach, packed

Stir it in at the very end so it wilts without turning gray. Kale works but needs 3 minutes of covered cooking instead of 1.

2 tbsp fresh parsley, chopped, for garnish

Flat-leaf parsley, not curly, for actual flavor. Basil is a good substitute if you are going for a more Italian profile.

Tips & Tricks

• Do not drain the pasta into a colander and rinse it. Rinsing washes off the surface starch that thickens your sauce, which is the single most common reason this dish turns out watery.
• Grate your own Parmesan. Pre-shredded cheese contains anti-caking agents that resist melting, and you will end up with gritty sauce no matter how long you stir.
• Pull the chicken at 160F (71C), not 165F (74C). Carryover cooking during the 3-minute rest brings it to a safe 165F (74C), and pulling early keeps the cubes juicy instead of chalky.
• Add the milk off a hard boil. If the pan is at a rolling boil when milk goes in, the proteins curdle and you get grainy sauce. Drop to a simmer first, then pour.

Step-by-Step Instructions

1. Season and sear the chicken

Pat the chicken dry, toss with 1/2 tsp kosher salt and 1/4 tsp pepper, and heat 2 tbsp olive oil in a 12-inch skillet over medium-high until it shimmers, about 2 minutes. Sear the chicken in a single layer for 5 to 6 minutes total, turning once, until golden brown on both sides and the internal temperature reads 160F (71C). Transfer to a plate; it will finish cooking later.

2. Bloom the garlic

Lower the heat to medium and add the minced garlic and red pepper flakes to the same pan with the rendered chicken fat. Cook for 30 seconds, stirring constantly, until fragrant but not browned; if the garlic darkens past pale gold, wipe the pan and start over, because burnt garlic will ruin the whole sauce.

3. Simmer the pasta

Pour in the chicken broth and 1.5 cups milk, then add the 12 oz pasta and 1 tsp Italian seasoning. Bring to a boil over high heat, then reduce to a steady simmer at 200F (93C) and cook uncovered for 12 to 14 minutes, stirring every 2 minutes so nothing sticks, until the pasta is al dente and the liquid has reduced by about half.

4. Melt in the Parmesan

Drop the heat to low, around 180F (82C), and stir in the 1 cup grated Parmesan in three additions, waiting for each to melt before adding the next. The sauce should turn glossy and coat the back of a spoon; if it looks tight, add reserved pasta water 2 tbsp at a time.

5. Return the chicken

Fold the seared chicken and any accumulated juices back into the skillet. Simmer at 180F (82C) for 3 minutes, just until the chicken hits 165F (74C) on an instant-read thermometer and the sauce bubbles gently at the edges.

6. Wilt the spinach and serve

Stir in the 2 cups baby spinach, cover, and cook for 1 minute at 180F (82C) until just wilted and bright green. Taste, adjust salt, garnish with parsley, and serve immediately with extra Parmesan.

Delicious Variations

Spicy Arrabbiata Version

double the red pepper flakes to 1 tsp, add 1 tbsp tomato paste with the garlic, and finish with 1/4 cup torn basil instead of parsley.

Lemon-Herb Version

swap the Italian seasoning for 1 tsp dried oregano, add the zest of 1 lemon with the Parmesan, and use 1/4 cup grated Pecorino instead of half the Parmesan.

Mushroom and Thyme Version

sear 8 oz sliced cremini mushrooms after the chicken, use 1 tsp fresh thyme instead of Italian seasoning, and keep everything else identical for a meatier, earthier plate.

👨‍🍳 Chef's Note: The 12-ounce pasta measurement is deliberate. A full pound soaks up too much liquid and leaves you with dry noodles, so resist the urge to dump in the whole box.
