Spinach and Garlic Spaghetti with Pecorino

Spinach and Garlic Spaghetti with Pecorino is one of those weeknight wonders that feels indulgent yet comes together in the time it takes water to boil. Bright, garlicky, and finished with nutty Pecorino, this pasta celebrates simple ingredients and straightforward technique. If you love quick dinners that taste like you spent hours in the kitchen, this is your new go-to.

Why this recipe works

The technique is all about layering flavor. A generous splash of extra virgin olive oil becomes fragrant when it meets minced garlic and a pinch of red pepper flakes. Toss in tender baby spinach so it wilts just enough, then finish with grated Pecorino for salty, savory richness. The seasoning is restrained — just salt, freshly ground black pepper, and a bit of Italian herb seasoning — letting each ingredient shine. It’s humble, elegant, and reliably delicious.

Ingredients

• 1 pound spaghetti
• 1/4 cup extra virgin olive oil
• 4 garlic cloves, minced
• 3/4 teaspoon red pepper flakes
• 1/2 teaspoon Italian herb seasoning
• 6 ounces fresh baby spinach
• 1/2 teaspoon salt
• 1/2 teaspoon freshly ground black pepper
• 2 ounces Pecorino or Parmesan cheese, grated

Notes on ingredients and swaps

This recipe is intentionally simple. Use good-quality extra virgin olive oil because its flavor carries through the dish. Fresh garlic is aromatic and bright; measure and mince it carefully so you don’t get any large, raw pieces. If you prefer a milder heat, reduce the red pepper flakes to 1/2 teaspoon, or omit them entirely for no heat. Choose Pecorino for a saltier, sharper finish or Parmesan if you want a slightly milder, nuttier note.

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan
• Tongs or pasta fork
• Colander
• Microplane or fine grater for cheese

Step-by-step directions

The directions below are written clearly and step-by-step so you can breeze through the cooking without having to pause and decipher instructions. Follow the order exactly for the best balance of texture and flavor.

1. Fill a large pot with water, add a generous pinch of salt, and bring it to a rolling boil over high heat.
2. While the water heats, prepare the garlic by peeling and mincing 4 garlic cloves. Grate 2 ounces of Pecorino or Parmesan and set it aside. Measure out the extra virgin olive oil, red pepper flakes, Italian herb seasoning, salt, and freshly ground black pepper.
3. Add 1 pound spaghetti to the boiling water and cook according to the package instructions until al dente. Stir occasionally to prevent the strands from sticking together.
4. As the pasta cooks, heat a large skillet over medium heat and pour in 1/4 cup extra virgin olive oil. Allow the oil to warm for about 30 seconds — it should be hot but not smoking.
5. Add the minced garlic to the warm oil and sauté for about 30 to 45 seconds, stirring frequently. Watch closely so the garlic becomes fragrant and just begins to turn golden; do not let it burn.
6. Stir in 3/4 teaspoon red pepper flakes and 1/2 teaspoon Italian herb seasoning. Cook for another 20 seconds to bloom the spices and release their aroma into the oil.
7. Add 6 ounces fresh baby spinach to the skillet. Using tongs or a spatula, toss the spinach in the garlic-infused oil until it wilts down and becomes bright green, about 1 to 2 minutes.
8. When the spaghetti is al dente, reserve about 1/2 cup of the starchy pasta cooking water and then drain the pasta in a colander.
9. Return the drained spaghetti to the pot or transfer it into the skillet with the wilted spinach and garlic oil. Toss thoroughly to combine so every strand is coated. If the pasta seems dry, add a splash of the reserved pasta water, a tablespoon at a time, until you reach a silky consistency that lightly clings to the noodles.
10. Season the combined pasta and greens with 1/2 teaspoon salt and 1/2 teaspoon freshly ground black pepper. Toss again to distribute the seasonings evenly.
11. Remove the pan from the heat and sprinkle 2 ounces grated Pecorino or Parmesan over the pasta. Toss once more so the cheese melts slightly and binds the sauce to the spaghetti.
12. Serve immediately, dividing the pasta among bowls and adding an extra grating of cheese or a drizzle of extra virgin olive oil, if desired.

Tips for perfect results

• Don’t overcook the spaghetti. Al dente pasta has a bit of bite and holds up better when tossed with oil and cheese.
• Reserve pasta water. That starchy water is the secret to making the sauce cling to the spaghetti and preventing a dry dish.
• Use a roomy skillet so the spinach can wilt evenly without overcrowding. If your pan is small, wilt the spinach in batches or transfer wilted greens out and add fresh until all are cooked.
• Adjust heat to preference. The red pepper flakes provide a gentle heat; add more or less to taste. If you’re serving kids or sensitive guests, reduce the amount by half.
• Freshly grate the Pecorino for the best texture and flavor. Pre-grated cheeses often include anti-caking agents and don’t melt as smoothly.

Variations and add-ins

This recipe is a brilliant canvas for add-ins. Here are a few ideas that keep the spirit of the dish intact while adding more depth or texture:

• Add toasted pine nuts or chopped walnuts for crunch. Stir them in just before serving so they stay crunchy.
• Toss in blanched or roasted vegetables like asparagus tips, cherry tomatoes, or sautéed mushrooms for more color and body.
• For a protein boost, stir in cooked white beans or bite-sized pieces of seared chicken breast.
• Finish with a squeeze of lemon juice or a teaspoon of lemon zest if you want a brighter, fresher finish. Add lemon sparingly so it complements rather than overpowers the Pecorino.

Make-ahead and storage

You can prepare the garlic oil and wilt the spinach in advance, storing them in the refrigerator for up to 24 hours. Cook the pasta just before serving and toss everything together so the texture stays lively. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat with a splash of water or olive oil to restore creaminess.

Serving suggestions

Serve this Spinach and Garlic Spaghetti with Pecorino as a light main course or as part of a larger meal. It pairs beautifully with a crisp green salad, crusty bread for mopping up the garlicky oil, or a simple antipasto. A chilled glass of white wine or sparkling water with lemon complements the dish’s bright flavors.

Common questions

Can I use frozen spinach? Yes. If using frozen spinach, thaw it and squeeze out as much liquid as possible before adding it to the skillet. Use the same 6 ounces measurement for a comparable result.

What if I don’t have Pecorino? Choose a good-quality Parmesan as an alternative. Both cheeses grate finely and melt into the pasta, though Pecorino will deliver a bit more sharpness and saltiness.

How much oil is too much? The 1/4 cup of extra virgin olive oil is intentional — it creates a silky coating for the spaghetti and carries the garlic and spice flavors. If you prefer a lighter dish, reduce the oil by a tablespoon or two, but maintain enough to coat the pasta comfortably.
