Ingredient Notes

• 1 pound penne pasta, cooked according to package directions (another small-shaped pasta such as ziti, rotini, small elbow, etc. may be substituted)
• 2 pounds boneless skinless chicken breast, diced into bite-sized pieces
• 1+ teaspoons kosher salt, or to taste
• 1+ teaspoons freshly ground black pepper, or to taste
• 3 to 5 cloves garlic, finely minced or pressed
• ½ cup unsalted butter, softened to room temp if possible
• ⅓ cup lemon juice, or to taste
• ¼ to ⅓ cup fresh Italian flat-leaf parsley, finely minced
• ½ cup freshly shaved Parmesan cheese, or to taste

Why this recipe works

The flavor trio of lemon, butter, and garlic is a classic for a reason: butter carries richness, garlic brings savory aromatics, and lemon cuts through the fat with bright acidity. Using bite-sized pieces of chicken lets each morsel get a quick sear for flavor while staying juicy. Penne or another small-shaped pasta catches every bit of sauce so you get lemony, buttery bites on every forkful. Finishing with parsley and shaved Parmesan gives freshness and salty umami to round everything out.

Prep tips before you start

• Bring a large pot of salted water to a boil for the pasta so it’s ready when the chicken is done. Salt the water generously — it should taste like the sea.
• Dice the chicken into uniform, bite-sized pieces so they cook evenly and quickly.
• Mince or press the garlic finely to avoid large raw pieces and to release maximum flavor.
• Soften the butter to room temperature so it melts into a silky sauce more easily. If you forget, you can melt it slowly in a pan before adding other ingredients.
• Measure the lemon juice; start with ⅓ cup and add more only if you want a brighter, more tart finish.

Flavor variations and swaps

If you’d like to customize, try one of these small changes: swap penne for rotini or ziti if you prefer a chunkier bite; add a handful of baby spinach or arugula at the end for green color and peppery notes; stir in a few tablespoons of cream for an extra-luxe texture. You can also add a pinch of red pepper flakes while cooking the chicken for a subtle heat boost.

Rewritten Step-by-Step Instructions

Follow these clear, ordered steps exactly as written; ingredient amounts above are the source of truth. The sequence mirrors the original method but is rewritten for clarity and ease.

1. Prepare the pasta: Bring a large pot of water to a rolling boil and add a generous pinch of salt. Add 1 pound penne pasta and cook according to package directions until al dente. Reserve about ½ cup of the pasta cooking water, then drain the pasta and set it aside while you cook the chicken and make the sauce.
2. Season the chicken: Place 2 pounds boneless skinless chicken breast diced into bite-sized pieces in a bowl. Sprinkle with 1+ teaspoons kosher salt and 1+ teaspoons freshly ground black pepper, adjusting to your taste. Toss to coat the chicken evenly.
3. Sear the chicken: Heat a large skillet over medium-high heat. Add a small splash of neutral oil if desired to prevent sticking. Add the seasoned chicken in a single layer and cook, stirring occasionally, until pieces are golden on the outside and cooked through, about 5–7 minutes depending on size. Work in batches if needed to avoid crowding the pan. Transfer the cooked chicken to a plate and set aside.
4. Gently cook the garlic: Reduce the heat to medium. Add 3 to 5 cloves garlic, finely minced or pressed, to the same skillet. Cook the garlic for about 30–60 seconds, stirring constantly, until fragrant but not browned. If the pan is dry, add a small knob of the ½ cup unsalted butter to prevent burning.
5. Create the lemon butter sauce: Add the remaining unsalted butter (total ½ cup) to the skillet and let it melt over low to medium heat, stirring to combine with the garlic. Pour in ⅓ cup lemon juice and stir until the sauce is smooth and slightly emulsified. Taste the sauce and add more lemon juice if you prefer a brighter flavor.
6. Combine chicken and sauce: Return the cooked chicken pieces to the skillet and stir to coat them evenly with the lemon butter garlic sauce. Let the chicken warm through in the sauce for 1–2 minutes so the flavors meld.
7. Toss with pasta: Add the cooked penne pasta to the skillet with the chicken and sauce. If the sauce seems too thick, add a few tablespoons of the reserved pasta cooking water at a time until you reach your desired consistency. Toss gently but thoroughly so each piece of pasta is coated with lemon butter and garlic.
8. Add parsley and Parmesan: Stir in ¼ to ⅓ cup fresh Italian flat-leaf parsley, finely minced, mixing it through the pasta. Remove the skillet from heat and sprinkle ½ cup freshly shaved Parmesan cheese over the top, tossing once more so the cheese melts slightly into the warm pasta. Taste and adjust with additional kosher salt, freshly ground black pepper, or lemon juice as needed.
9. Serve immediately: Divide the Lemon Butter Garlic Chicken Pasta among plates or bowls. Garnish with additional parsley and shaved Parmesan, if desired. Serve hot and enjoy.

Serving suggestions

This dish is lovely on its own, but you can round out the meal with simple sides:

• A crisp green salad dressed with lemon vinaigrette to echo the pasta’s citrus notes.
• Roasted or steamed vegetables like asparagus, green beans, or broccoli for color and crunch.
• Crusty bread or garlic bread to soak up any leftover lemon butter sauce.

Make-ahead and storage

To store: Cool leftovers to room temperature, then refrigerate in an airtight container for up to 3 days. Reheat gently in a skillet over low heat with a splash of water or broth to loosen the sauce, or microwave in short bursts, stirring between intervals.

To freeze: This pasta is best refrigerated rather than frozen because the texture of the chicken and pasta can change after freezing. If you must freeze, place in a freezer-safe container for up to 1 month and thaw overnight in the refrigerator before reheating.

Common troubleshooting

• If the sauce is grainy or separates, remove the pan from heat and whisk in a tablespoon of reserved pasta water at a time until it smooths out.
• If the chicken is dry, it may have been overcooked. For juicier results, sear the pieces quickly on higher heat and finish in the sauce for less time.
• If the dish tastes flat, brighten it with an extra squeeze of lemon juice and a pinch more salt.

Nutrition snapshot (estimate per serving)

This will vary with portion size and exact ingredients, but expect a satisfying mix of protein from the chicken, carbohydrates from the pasta, and fat from the butter and Parmesan. For lighter options, you can swap half the butter for olive oil or reduce the pasta portion while adding more vegetables.
