Parsley Las Vegas Recipe: Herb-Forward Pasta

Parsley Las Vegas is a bold, herb-driven pasta dish that puts a generous handful of fresh parsley at the center of the plate, not just as a garnish. It combines a silky, garlicky olive oil sauce with a bright hit of lemon and a gentle heat from red pepper flakes, all clinging to al dente spaghetti. The name is playful and not tied to a specific Italian region—it is a modern, crowd-pleasing creation that proves simple ingredients can make a genuinely memorable weeknight dinner.

Ingredients

12 oz (340 g) dried spaghetti or linguine
1 cup (30 g) fresh flat-leaf parsley, tightly packed, stems removed and finely chopped (about 1 large bunch)
1/2 cup (120 ml) extra-virgin olive oil
6 cloves garlic, thinly sliced
1/2 tsp (1 g) red pepper flakes (adjust to taste)
1 tsp (5 g) kosher salt, plus more for pasta water
1/2 tsp (1 g) black pepper, freshly ground
1 lemon, zested and juiced (about 1 tbsp zest and 2 tbsp juice)
1/2 cup (50 g) grated Parmesan cheese, plus more for serving
1/4 cup (60 ml) pasta cooking water, reserved

Instructions

Bring a large pot of salted water to a rolling boil (about 2 tbsp salt per 4 quarts of water). Add the spaghetti and cook according to package instructions until al dente, usually 8–10 minutes.
While the pasta cooks, heat the olive oil in a large skillet over medium heat. Add the sliced garlic and red pepper flakes. Sauté gently for 2–3 minutes until the garlic is fragrant and just starting to turn golden at the edges—do not let it brown or burn, as that will make the sauce bitter.
Remove the skillet from the heat and stir in the chopped parsley, lemon zest, lemon juice, kosher salt, and black pepper. The residual heat will wilt the parsley slightly and release its aroma.
Reserve 1 cup (240 ml) of pasta cooking water, then drain the pasta. Add the hot pasta to the skillet with the parsley mixture.
Return the skillet to medium-low heat. Toss the pasta with tongs, adding the reserved pasta water a few tablespoons at a time, until the sauce emulsifies and coats each strand. You may not need all the water—use just enough to create a silky, non-greasy sauce.
Remove from heat and sprinkle in the grated Parmesan. Toss vigorously to incorporate. Taste and adjust seasoning with more salt, pepper, or lemon juice if needed.
Serve immediately in warm bowls, topped with extra Parmesan and a pinch of red pepper flakes if desired.

Tips

Use flat-leaf parsley, not curly. Curly parsley is milder and more fibrous; flat-leaf (Italian) parsley has a cleaner, more robust flavor that holds up better in this dish.
Chop parsley finely but not to a paste. You want flecks of green throughout, not a puree. A sharp chef’s knife is your best tool.
Reserve plenty of pasta water. The starchy water is the secret to a creamy, emulsified sauce without adding cream. If you forget, you can use plain hot water, but the texture will be thinner.
Don’t skip the resting step. Letting the pasta sit in the sauce for 1–2 minutes off the heat before serving allows the flavors to meld and the sauce to cling better.

Serving Suggestions

This pasta is a complete meal on its own, but it pairs beautifully with a crisp green salad dressed with lemon vinaigrette and a glass of dry white wine like Pinot Grigio or Sauvignon Blanc. For a heartier dinner, serve alongside grilled chicken or shrimp—just cook them simply with salt, pepper, and a little olive oil to let the parsley pasta shine. A side of crusty bread is perfect for sopping up any remaining sauce.

Variations

Add protein: Toss in 1 cup (150 g) of cooked, shredded rotisserie chicken or 8 oz (225 g) of sautéed shrimp in step 5. If adding shrimp, cook them separately until pink and opaque, then fold in at the end.
Make it vegan: Omit the Parmesan and use 2 tbsp (15 g) of nutritional yeast or a vegan Parmesan alternative. The sauce will be slightly less rich but still delicious.
Try a different herb: Replace half the parsley with fresh basil or mint for a different flavor profile. Basil adds sweetness, mint adds a cool note—both work well with lemon and garlic.
Add vegetables: Sauté 1 cup (150 g) of cherry tomatoes or 2 cups (60 g) of fresh spinach in the skillet before adding the parsley. This adds color and nutrients without overwhelming the herb focus.
Go gluten-free: Use gluten-free spaghetti; just be careful not to overcook it, as gluten-free pasta tends to become mushy quickly.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. The pasta will absorb some sauce as it sits, so when reheating, add a splash of water or olive oil to loosen it. Reheat in a skillet over medium heat for 3–5 minutes, stirring frequently, or in the microwave in 30-second bursts until hot. Avoid reheating more than once to preserve texture. This dish is best enjoyed fresh, but it still makes a satisfying lunch the next day.

Frequently Asked Questions

Can I use dried parsley instead of fresh? No—dried parsley lacks the bright, grassy flavor and will turn dusty. Fresh flat-leaf parsley is essential for this recipe. If you can’t find it, you could substitute fresh cilantro or a mix of fresh basil and arugula, though the flavor will change.

Why is my sauce oily instead of creamy? This usually happens when the pasta water is added too quickly or not enough is used. The key is to add the water gradually while tossing constantly, allowing the starch to emulsify with the oil. Also, make sure the skillet is not too hot when you add the water—medium-low is ideal.

Can I make this ahead of time? You can prep the parsley, garlic, and lemon zest/juice up to a day ahead and store them in the refrigerator. Cook the pasta and sauce just before serving. The finished dish does not freeze well, as the sauce will separate and the pasta will become mushy.

Is this dish spicy? It has a gentle warmth from the red pepper flakes, but you can adjust the amount to suit your taste. For a milder version, use just a pinch; for more heat, add up to 1 tsp (2 g) of flakes.

What if I don’t have a lemon? You can substitute 2 tbsp (30 ml) of white wine vinegar or apple cider vinegar mixed with 1 tsp of water, but the flavor will be slightly more acidic and less floral. Alternatively, use 1 tbsp (15 ml) of fresh lime juice, though it will change the character of the dish.

Can I use a different pasta shape? Absolutely—this sauce works well with any long pasta like fettuccine, bucatini, or even penne. Just adjust the cooking time to the package instructions and remember to reserve extra pasta water for thicker shapes.
