Instructions

  1. Bring a large pot of salted water to a boil. Wash and dry produce. Trim and quarter zucchini lengthwise; cut crosswise into ½-inch-thick pieces. Peel and mince garlic. Zest and quarter lemon.
  2. Once water is boiling, add spaghetti to pot. Cook, stirring occasionally, until al dente, 9-11 minutes. Reserve 1 cup pasta cooking water, then drain. (Keep empty pot handy for step 5.)
  3. While pasta cooks, heat a drizzle of olive oil in a large, preferably nonstick, pan over medium-high heat. Add zucchini; cook, stirring occasionally, until browned and softened, 4-6 minutes. Season with salt and pepper. Turn off heat; transfer to a plate. Wipe out pan.
  4. Meanwhile, pat chicken dry with paper towels and season all over with Italian Seasoning, salt and pepper. Once zucchini is done, heat a large drizzle of oil in same pan over medium-high heat. Add chicken and cook until browned and cooked through, 3-5 minutes per side. Turn off heat; transfer to a cutting board to rest.
  5. Heat a drizzle of olive oil in pot used for spaghetti over medium-high heat. Add garlic, half the lemon zest and a pinch of chili flakes. Cook, stirring, until fragrant, 20-30 seconds. Stir in ½ cup reserved pasta cooking water, stock concentrate and juice from two lemon wedges. Simmer until thickened, 1-2 minutes. Turn off heat.
  6. Add drained spaghetti, zucchini, sour cream and 1 TBSP butter to pot with sauce; toss to coat. Add half the Parmesan and season with salt and pepper. TIP: If needed, stir in more reserved pasta cooking water a splash at a time until spaghetti is coated in a creamy sauce. Divide pasta between bowls. Top with chicken, remaining Parmesan, remaining lemon zest and a pinch of chili flakes if desired. Serve with any remaining lemon wedges on the side.

Recipe Tips

Reserve more pasta water than you think you’ll need; it’s the key to a silky sauce.

For extra browning on the chicken, make sure the pan is hot before adding the oil.

Adjust the chili flakes to your heat preference; start with a pinch and add more at the end.

FAQ

Can I use a different pasta shape?

Yes, any long pasta like linguine or fettuccine works well. Adjust cooking time according to package directions.

How do I make this dish dairy-free?

Substitute the sour cream with a dairy-free alternative, use vegan butter or olive oil and omit the Parmesan or use a dairy-free cheese.

Can I add other vegetables?

Absolutely! Bell peppers, mushrooms or spinach would be great additions. Sauté them with the zucchini or add at the end.
