Last Tuesday I came home exhausted and threw this together in twenty minutes. The way the bright lemon hit the rich cream made my entire kitchen smell like an Italian bistro at sunset. Sometimes the simplest meals surprise you the most.

My sister called halfway through cooking that night, and I had to hold the phone with one shoulder while stirring the sauce. She could hear the sizzling garlic through the receiver and demanded the recipe immediately.

Ingredients

  • Thin spaghetti: The delicate strands catch the creamy sauce beautifully
  • Fresh baby spinach: Wilts down into silky ribbons without any bitter taste

  • Heavy cream: Creates that luxurious restaurant style sauce

That Tuesday night dinner turned into a weekly tradition. Now my sister texts me every time she makes it, usually with a photo of her empty plate.

Make It Your Own

Grilled chicken strips or pan seared shrimp transform this into a hearty dinner. The gentle sweetness of shrimp pairs especially beautifully with the sharp lemon.

Pasta Swaps

Whole wheat spaghetti adds nutty depth and extra fiber. Gluten free blends work surprisingly well here since the rich sauce masks any texture differences.

Wine Pairing Notes

A crisp Sauvignon Blanc cuts through the cream while echoing the citrus notes. Pinot Grigio works beautifully if you prefer something lighter and more floral.

  • Chill your white wine for at least 30 minutes before serving
  • The acidity in wine complements the rich sauce perfectly
  • Pour a little extra to sip while you cook

Recipe Questions & Answers

Can I prepare this dish ahead of time?

This pasta is best served immediately after cooking for optimal creaminess and texture. However, you can prepare individual components in advance: cook the pasta, chop vegetables, and measure dry ingredients. Then assemble and cook just before serving.

What can I substitute for heavy cream?

Use crème fraîche, Greek yogurt, or mascarpone for different flavor profiles. For a lighter option, try half-and-half or milk combined with a cornstarch slurry to achieve similar creaminess.

How do I prevent the sauce from breaking?

Keep the heat at medium or medium-low throughout cooking. Add the lemon juice slowly while stirring constantly. If the sauce appears to separate, whisk in a splash of pasta water or cold cream to bring it back together.

Can I add protein to this dish?

Absolutely. Grilled chicken breast, pan-seared shrimp, or crispy bacon work wonderfully. Cook protein separately and toss it with the pasta just before serving to maintain optimal texture.

What pasta shape works best?

Thin spaghetti is ideal as it cooks quickly and holds the delicate cream sauce well. Linguine, fettuccine, or angel hair pasta are excellent alternatives that provide similar results.

How should I store leftovers?

Store in an airtight container for up to 2 days. Reheat gently on the stovetop over low heat with a splash of pasta water or cream to restore creaminess, as the pasta will absorb sauce upon cooling.

What You Need

Pasta

01 14 oz thin spaghetti
02 Salt for pasta water

Vegetables

01 7 oz fresh baby spinach
02 2 cloves garlic, finely minced
03 Zest of 1 lemon
04 Juice of 1 large lemon

Sauce

01 2 tablespoons unsalted butter
02 3/4 cup plus 1 tablespoon heavy cream
03 1/2 cup grated Parmesan cheese
04 Freshly ground black pepper to taste

Garnish

01 Extra lemon zest
02 Additional Parmesan cheese for serving

How to Make It

Step 01

Prepare the pasta: Bring a large pot of salted water to a boil. Cook the spaghetti according to package instructions until al dente. Reserve 1/2 cup of pasta water, then drain in a colander.

Step 02

Build the garlic base: While the pasta cooks, heat the butter in a large skillet over medium heat. Add the minced garlic and cook for 1 minute until fragrant, taking care not to brown.

Step 03

Wilt the spinach: Add the fresh spinach to the skillet and sauté for 2 to 3 minutes until completely wilted. Stir in the lemon zest.

Step 04

Create the cream sauce: Pour in the heavy cream and bring to a gentle simmer. Stir in the lemon juice and Parmesan cheese, allowing the cheese to melt and the sauce to thicken slightly.

Step 05

Combine and emulsify: Add the drained spaghetti to the skillet, tossing gently to coat thoroughly in the sauce. Gradually add reserved pasta water as needed to achieve a silky, creamy consistency.

Step 06

Season and finish: Season generously with freshly ground black pepper and adjust salt to taste.

Step 07

Plate and serve: Transfer to serving plates immediately while the sauce is still hot. Garnish with extra lemon zest and additional Parmesan cheese.
