Why You’ll Love This Recipe

• One pan, weeknight-friendly: Pasta cooks right in the skillet for a quick dinner.
• Big garlic-butter flavor: The sauce clings to every noodle without feeling heavy.
• Spinach adds balance: It melts in at the end for color and freshness.
• Flexible: Easy to add chicken, shrimp, mushrooms, or extra veggies.

Ingredients You’ll Need

• Pasta: spaghetti, linguine, or fettuccine work best (broken in half to fit the skillet).
• Butter: unsalted gives you control over seasoning.
• Olive oil: helps keep the butter from browning too quickly.
• Garlic: fresh minced or thinly sliced for the most punch.
• Broth: chicken or vegetable broth for deeper flavor than water.
• Baby spinach: fresh is ideal; it wilts in seconds.
• Parmesan: finely grated melts smoothly into the sauce (avoid pre-shredded if you can).
• Lemon: zest and juice to brighten and balance the butter.
• Crushed red pepper: optional, but great for gentle heat.
• Salt & black pepper: season in layers.

How to Make Skillet Garlic Butter Pasta with Spinach

This method builds a glossy sauce using butter, starch from the pasta, and Parmesan—no cream needed.

• 1) Bloom the garlic: Warm olive oil and butter in a large skillet over medium heat. Add garlic and cook just until fragrant (don’t let it brown).
• 2) Simmer the pasta: Add broth, a pinch of salt, and the pasta. Bring to a simmer and cook, tossing often, until noodles are al dente and most liquid is absorbed.
• 3) Make it silky: Lower heat. Add more butter, Parmesan, and a splash of broth if needed. Toss until glossy and coated.
• 4) Wilt the spinach: Add spinach by handfuls, tossing until just wilted.
• 5) Finish: Add lemon zest and juice, black pepper, and optional crushed red pepper. Taste and adjust salt.

Food Stylist Tips for the Best Garlic Butter Sauce

• Use finely grated Parmesan: It melts into the sauce instead of clumping.
• Keep the heat moderate: High heat can separate the butter sauce or over-brown the garlic.
• Emulsify with tossing: Stir and toss vigorously near the end—this helps the butter, starch, and cheese come together.
• Save a splash of liquid: If the pasta tightens up, add 1–3 tablespoons broth and toss to loosen.

Easy Variations

• Add protein: Stir in shredded rotisserie chicken, seared shrimp, or sliced Italian sausage.
• Make it extra veg-forward: Add mushrooms (sauté first), peas, or chopped asparagus.
• Go creamy (optional): Add 2–3 tablespoons cream cheese or a splash of heavy cream at the end.
• Make it spicy: Add more crushed red pepper or a drizzle of chili oil before serving.

What to Serve With It

• Simple salad: arugula with lemon vinaigrette or a classic Caesar.
• Garlic bread: yes, double garlic is always a good idea.
• Roasted vegetables: broccoli, Brussels sprouts, or zucchini.
• Wine pairing: Pinot Grigio or Sauvignon Blanc for a bright match.

Storage & Reheating

• Store: Cool and refrigerate in an airtight container for up to 3 days.
• Reheat: Warm in a skillet over medium-low with a splash of broth or water, tossing until glossy again.
• Freeze: Not ideal—butter/cheese sauces can separate after thawing.

Skillet Garlic Butter Pasta with Spinach (Recipe)

Serves: 4
Time: 20 minutes

Ingredients

• 12 oz spaghetti (or linguine), broken in half
• 2 tbsp olive oil
• 5 tbsp unsalted butter, divided
• 5–6 cloves garlic, minced or thinly sliced
• 3 cups low-sodium chicken broth (or vegetable broth)
• 1/2 tsp kosher salt, plus more to taste
• 1/2 tsp black pepper, plus more to taste
• 3–4 oz baby spinach
• 3/4 cup finely grated Parmesan, plus more for serving
• 1 tsp lemon zest
• 2 tbsp lemon juice (about 1/2 lemon), more to taste
• 1/4 tsp crushed red pepper flakes (optional)

Instructions

• In a large, deep skillet over medium heat, warm the olive oil and 3 tablespoons of the butter. Add garlic and cook 30–60 seconds until fragrant, stirring constantly.
• Add broth, salt, pepper, and pasta. Bring to a simmer. Cook 10–12 minutes, stirring and tossing often, until pasta is al dente and most of the liquid is absorbed (add a splash more broth if needed as it cooks).
• Reduce heat to low. Add remaining 2 tablespoons butter and the Parmesan. Toss vigorously until the sauce looks glossy and coats the pasta. If it seems tight, add 1–3 tablespoons broth and toss again.
• Add spinach in handfuls, tossing until just wilted.
• Turn off the heat. Stir in lemon zest, lemon juice, and crushed red pepper (if using). Taste and adjust salt and pepper. Serve hot with extra Parmesan.

Notes

• Garlic tip: If your stovetop runs hot, pull the skillet slightly off the burner while adding garlic to prevent browning.
• Cheese tip: Grate Parmesan finely so it melts smoothly into the sauce.
• Spinach tip: Add at the end so it stays bright green and tender.
