Ingredients
Instructions
- Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente, 9-11 minutes. Reserve ½ cup of pasta cooking water, then drain the spaghetti.
- While the pasta cooks, prepare the vegetables: trim and halve the zucchini lengthwise, then cut crosswise into ¼-inch half-moons. Thinly slice the chili pepper. Rinse the shrimp under cold water and pat dry with paper towels.
- Heat a large drizzle of olive oil in a large pan over medium-high heat. Add the zucchini and as much sliced chili as you like. Cook, stirring occasionally, until the zucchini is lightly browned, 2-3 minutes.
- Push the zucchini mixture to one side of the pan. Add another drizzle of olive oil to the empty side. Add the shrimp and cook, stirring occasionally, until opaque and cooked through, 3-4 minutes.
- Add the drained spaghetti, garlic herb butter, half the Parmesan (reserve the rest for serving) and ¼ cup of the reserved pasta cooking water to the pan. Season generously with salt and pepper. Toss everything together until well combined. If the pasta seems dry, add more reserved cooking water a splash at a time until the sauce coats the spaghetti nicely.
- Divide the pasta between bowls. Top with the remaining Parmesan and a drizzle of olive oil. Garnish with any remaining sliced chili, if desired and serve immediately.
Recipe Tips
For a milder dish, remove the seeds and membranes from the chili pepper before slicing or use only half.
Reserve more pasta water than you think you’ll need-it’s the key to a silky sauce.
Pat the shrimp dry thoroughly to ensure they sear nicely and don’t steam.
FAQ
Can I use a different type of pasta?
Yes, linguine, fettuccine or even penne work well. Adjust cooking time according to package directions.
How can I make this dish dairy-free?
Use a dairy-free butter alternative and omit the Parmesan or substitute with a vegan Parmesan-style topping.
Can I add other vegetables?
Absolutely! Bell peppers, cherry tomatoes or spinach would be great additions. Add them with the zucchini and adjust cooking time as needed.
