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

This healthy garlic parmesan chicken pasta is the dinner I make on the nights when I want something creamy but don't want to feel sluggish afterward. Everything cooks in one pan, and the whole thing is on your table in about 30 minutes.

The trick is using a little reserved pasta water instead of heavy cream. It mixes with the parmesan and garlic to make a silky sauce that clings to every piece of pasta. You get all the comfort of a restaurant pasta dish with a fraction of the fat.

If you're new to one-pan cooking, this is a great place to start. Fewer dishes, simple ingredients, and a sauce that comes together right in the skillet. Let's cook.

About the Ingredients

12 oz (340g) boneless, skinless chicken breast, cut into 1-inch pieces

Chicken breast keeps this lean and high in protein. You can swap in chicken thighs for a juicier bite, but add 2 minutes to the cook time since thighs release more moisture.

10 oz (280g) whole wheat penne or rigatoni

Whole wheat pasta adds fiber and holds up well in a thick sauce. If you only have regular pasta, use it and reduce the broth by 1/4 cup since it absorbs less liquid.

2 tbsp olive oil

Regular or extra virgin both work here. Buy olive oil in a dark bottle and store it away from the stove, since heat makes it go stale faster.

5 cloves garlic, finely minced

Fresh garlic gives the best flavor, but 1 1/4 tsp garlic powder works in a pinch. Add the powder with the broth, not the hot oil, so it doesn't burn.

2 1/2 cups (600ml) low-sodium chicken broth

Low-sodium lets you control the salt. Vegetable broth is a fine substitute if you're cooking for a vegetarian who eats parmesan.

1 cup (240ml) 2% milk

Milk keeps the sauce light but creamy. For a dairy-free version, use unsweetened oat milk and add 1 extra tablespoon of parmesan for body.

3/4 cup (60g) freshly grated parmesan cheese

Grate it yourself from a block, because pre-shredded parmesan has anti-caking starch that makes the sauce grainy. Pecorino Romano is a sharper swap.

1 cup (150g) cherry tomatoes, halved

Cherry tomatoes add sweetness and a pop of color. In winter, use 1 cup of chopped sun-dried tomatoes instead for a deeper, richer flavor.

1 tsp Italian seasoning, 1/2 tsp salt, 1/4 tsp black pepper

A simple blend you likely already have. If you're out of Italian seasoning, mix 1/2 tsp oregano, 1/2 tsp basil and a pinch of thyme.

2 cups (60g) fresh baby spinach

Spinach wilts down to almost nothing, so don't skip it. Kale works too, but add it 3 minutes earlier so it softens properly.

2 tbsp fresh parsley, chopped, plus extra parmesan for serving

Parsley brightens the whole dish. No parsley? A squeeze of fresh lemon juice at the end gives a similar fresh finish.

Tips & Tricks

Don't Skip the Pasta Water

The starchy water is what makes the sauce creamy. Scoop out 1 cup before draining, and add it a splash at a time until the sauce coats the back of a spoon.

Watch the Garlic

Garlic burns in seconds and turns bitter. Add it once the chicken is out of the pan and the heat is lowered, and stir constantly for 30 seconds.

Salt at the End

Parmesan is salty, and broth varies in sodium. Taste the sauce before adding any extra salt, then adjust.

Keep Chicken Pieces Even

Cut every piece to about 1 inch so they cook at the same rate. Uneven pieces mean dry edges and pink centers.

Step-by-Step Instructions

1. Boil the Pasta

Bring a large pot of salted water to a rolling boil, add the pasta and cook 1 minute less than the package says, about 8 minutes for whole wheat penne. Scoop out 1 cup of pasta water, then drain. The pasta should still have a slight bite, since it finishes cooking in the sauce.

2. Season the Chicken

Pat the chicken dry with paper towels and toss it with the Italian seasoning, salt and pepper. Dry chicken browns instead of steaming, which is what gives you that golden crust and better flavor.

3. Sear the Chicken

Heat 1 tbsp olive oil in a large deep skillet over medium-high heat (375°F / 190°C). Add the chicken in a single layer and cook 4 minutes without moving it, then flip and cook 3 more minutes until golden brown on both sides and the internal temperature reads 165°F (74°C). Transfer to a plate.

4. Bloom the Garlic

Lower the heat to medium (300°F / 150°C), add the remaining 1 tbsp olive oil and the garlic, and stir constantly for 30 seconds until fragrant. You want it golden and smellable, never brown, because burnt garlic ruins the whole sauce.

5. Build the Sauce

Pour in the broth and milk, then scrape the browned bits off the bottom of the pan with a wooden spoon. Add the cherry tomatoes and simmer 5 minutes until the tomatoes soften and the liquid reduces slightly, with small bubbles around the edges.

6. Finish the Pasta

Add the drained pasta, chicken and any juices back to the skillet. Sprinkle in the parmesan and toss over medium-low heat (275°F / 135°C) for 2 minutes, adding reserved pasta water 2 tbsp at a time until the sauce is glossy and coats the pasta.

7. Wilt the Spinach

Fold in the baby spinach and cook 1 minute, just until it wilts and turns deep green. Stirring it in at the very end keeps its color bright instead of dull and olive-colored.

8. Serve and Garnish

Taste and adjust the salt, then top with fresh parsley and extra parmesan. Serve right away, because this pasta is at its creamiest in the first 10 minutes.

Delicious Variations

Spicy Arrabbiata Version

Add 1/2 tsp red pepper flakes with the garlic and swap the milk for 1 cup of crushed tomatoes. You get a bold, spicy sauce with the same creamy parmesan finish.

Lemon Herb Chicken Pasta

Use 1 tbsp lemon zest in the sauce and finish with 2 tbsp lemon juice instead of parsley. It tastes lighter and brighter, perfect for spring.

Mushroom Parmesan Pasta

Replace the chicken with 12 oz (340g) sliced cremini mushrooms and cook them 5 minutes before adding the garlic. A great meatless Monday option that still feels hearty.
