Ingredients You’ll Need

Pasta Base

• 8 ounces (225g) spaghetti or linguine — Provides the foundation of the dish and holds the buttery lemon sauce beautifully.
• Salted pasta water — Enhances the pasta flavor and helps create the smooth sauce consistency.

Lemon Garlic Butter Sauce

• 4 tablespoons (56g) unsalted butter — Creates a rich, smooth base that carries the garlic and lemon flavors.
• 1 tablespoon (15ml) olive oil — Helps prevent the butter from burning while adding a subtle fruity flavor.
• 4–5 cloves garlic, minced (about 1 tablespoon) — Provides the main savory aroma and depth of flavor.
• 1 large lemon, zest and juice — Adds brightness, acidity, and fresh citrus fragrance.
• ¼ teaspoon red pepper flakes (optional) — Adds a gentle spicy kick that enhances the garlic flavor.
• Salt, to taste — Balances and enhances all ingredients.
• Freshly ground black pepper, to taste — Adds warmth and a mild peppery finish.

Finishing Ingredients

• 4 cups (about 120g) fresh baby spinach — Adds color, nutrients, and a fresh vegetable element.
• ½ cup (50g) grated Parmesan cheese — Provides salty richness and helps thicken the sauce.

Step-by-Step Instructions

1. Cook the Pasta

Bring a large pot of salted water to a rolling boil. Cook the spaghetti or linguine for 8–10 minutes until just al dente, then reserve ½ cup of pasta water before draining.

2. Prepare the Garlic Butter Sauce

Heat butter and olive oil in a large skillet over medium heat until the butter melts and begins to foam. Add minced garlic and red pepper flakes, stirring constantly for 1–2 minutes until fragrant without allowing the garlic to brown.

3. Add the Lemon Flavor

Stir the lemon zest into the butter mixture, then add the fresh lemon juice. Allow the sauce to gently simmer for about 30 seconds so the flavors combine.

4. Wilt the Spinach

Add fresh baby spinach directly into the skillet and toss with the lemon garlic butter sauce. Cook for 1–2 minutes until the spinach softens while maintaining its bright green color.

5. Combine Pasta and Sauce

Add the drained pasta into the skillet and toss thoroughly until every strand is coated. Slowly add reserved pasta water as needed to create a silky sauce that clings to the pasta.

6. Finish with Parmesan

Remove the skillet from heat and stir in grated Parmesan cheese until melted and incorporated. Adjust seasoning with salt and black pepper before serving.

7. Serve Immediately

Plate the pasta while warm and garnish with extra Parmesan, cracked pepper, or fresh herbs such as basil or parsley if desired.

Recipe Notes & Tips

• Reserve Pasta Water — The starch in pasta water helps emulsify the butter and cheese into a smooth sauce that coats every strand.
• Avoid Browning Garlic — Cook garlic gently because burnt garlic can create a bitter flavor that affects the entire dish.
• Use Fresh Lemon — Freshly squeezed lemon juice and zest provide a brighter flavor than bottled alternatives.
• Add Spinach at the End — Short cooking keeps spinach tender, colorful, and nutrient-rich.
• Use Fresh Parmesan — Freshly grated cheese melts more smoothly and creates better sauce texture.
• Control Sauce Thickness — Add pasta water gradually until you reach the desired glossy consistency.

The combination of acidity from lemon, richness from butter and cheese, and savory garlic creates a balanced flavor profile that feels indulgent without requiring heavy ingredients. With approximately 380 calories per serving, this pasta offers a satisfying meal with carbohydrates for energy, protein from Parmesan, and vitamins from fresh spinach.
