Why you’ll love this recipe

This Lemon Butter Garlic Chicken Pasta delivers balanced brightness from lemon, richness from butter, and an aromatic pop from garlic. The sauce is light but clingy, letting each piece of pasta wear a glossy coat of flavor. The diced chicken cooks quickly and melds into the noodles, so the entire dish is done in about the time it takes to boil and toss pasta. It’s flexible, family-friendly, and perfect for meal prep or a last-minute dinner party.

Ingredients

• 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

Make-ahead and substitutions

Want to prep in advance? Dice the chicken and mince the garlic a day ahead, and keep them refrigerated. You can cook the pasta earlier and toss it with a little oil to prevent sticking; warm gently in a skillet with the sauce when ready to serve. If you don’t have penne, any small-shaped pasta works well to catch the sauce. For a lighter finish, reduce the butter slightly or add a splash of reserved pasta water to loosen the sauce while keeping it glossy.

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan
• Tongs or slotted spoon
• Measuring cups and spoons
• Cutting board and knife

Taste and texture notes

This recipe balances three main elements: acidity from lemon, richness from butter, and aromatics from garlic. The lemon juice brightens and cuts through the butter so the dish never feels heavy. The parsley adds herbaceous freshness and contrast, while freshly shaved Parmesan brings umami and a silky finish. For maximum impact, use freshly squeezed lemon juice and freshly grated or shaved Parmesan.

Step-by-step instructions

Follow these clear steps to make the Lemon Butter Garlic Chicken Pasta. The directions have been rewritten to be concise and easy to follow while preserving the exact ingredient amounts listed above. Keep the same order as the original recipe so everything comes together smoothly.

1. Cook the pasta: Bring a large pot of salted water to a boil. 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.
2. Prepare the chicken: While the pasta cooks, pat 2 pounds boneless skinless chicken breast dry and dice into bite-sized pieces. Season the diced chicken with 1+ teaspoons kosher salt and 1+ teaspoons freshly ground black pepper, or to taste. Use at least the listed amounts and adjust after cooking if needed.
3. Sauté the chicken: Heat a large skillet over medium-high heat. Once hot, add a small amount of neutral oil if your pan needs it, then add the seasoned diced chicken in a single layer. Cook, stirring occasionally, until the chicken pieces are cooked through and lightly browned on the edges, about 6–8 minutes depending on the size of the pieces. Remove the cooked chicken to a plate and keep warm.
4. Sauté the garlic: Reduce the heat to medium. In the same skillet, add 3 to 5 cloves garlic, finely minced or pressed. Sauté the garlic briefly—about 30–60 seconds—until fragrant. Watch closely so it does not brown, which can make it bitter.
5. Create the lemon-butter sauce: Add ½ cup unsalted butter, softened, to the skillet with the garlic. Stir until the butter melts and becomes a smooth sauce. Pour in ⅓ cup lemon juice, or to taste, stirring to combine. Allow the sauce to warm through and slightly thicken for 1–2 minutes. Taste and adjust seasoning with additional salt, pepper, or lemon juice if desired.
6. Toss in pasta and chicken: Return the cooked chicken to the skillet, then add the drained penne pasta. Toss everything together until the pasta and chicken are evenly coated with the lemon butter sauce. If the sauce feels too thick or you prefer a looser coating, add a splash of the reserved pasta cooking water and toss until you reach the desired consistency.
7. Add parsley and Parmesan: Stir in ¼ to ⅓ cup fresh Italian flat-leaf parsley, finely minced, distributing it evenly through the pasta. Sprinkle ½ cup freshly shaved Parmesan cheese over the pasta and toss gently to combine. Taste and adjust with more salt, pepper, lemon juice, or Parmesan as needed.
8. Serve: Divide the pasta among plates or a large serving bowl. Garnish with additional parsley and a few extra shavings of Parmesan if desired. Serve immediately while warm.

Pro tips for success

• Use room-temperature butter so it melts evenly into the sauce without separating.
• Reserve pasta water before draining — its starch helps bind the sauce to the noodles and gives a silky texture.
• Don’t overcook the chicken. Cutting it into bite-sized pieces shortens cooking time and helps it stay tender.
• Adjust the lemon juice to your taste. Start with the measured ⅓ cup and add more if you want a tangier punch.
• Freshly shaved Parmesan will melt differently than pre-grated cheese and gives the best texture and flavor.

Make it your own

This Lemon Butter Garlic Chicken Pasta is an excellent canvas for customization. Stir in a handful of baby spinach at the end and let it wilt for extra veggies. Add a pinch of red pepper flakes with the garlic for heat. For a creamier sauce, stir in a few tablespoons of plain yogurt or a splash of cream at the sauce stage. For added crunch, sprinkle toasted breadcrumbs or chopped toasted almonds on top just before serving.

Storage and reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove over low heat with a splash of water or reserved pasta water to loosen the sauce, or microwave in short intervals, stirring between bursts so the butter and cheese re-melt evenly. Freshen with a squeeze of lemon or a sprinkle of fresh parsley before serving.

Serving suggestions

Pair the Lemon Butter Garlic Chicken Pasta with a crisp green salad, crusty bread for mopping up sauce, and a chilled glass of white wine or sparkling water with lemon. A simple side of roasted vegetables or steamed asparagus complements the brightness of the dish.
