4 cups fresh spinach leaves Packed; stems removed.

½ cup grated Parmesan Finely grated for smooth sauce.

¼ cup toasted pine nuts Optional; walnuts work too.

2 cloves garlic, minced Fresh gives best aroma.

½ cup heavy cream For richness; can substitute half‑and‑half.

3 tbsp extra‑virgin olive oil Helps emulsify the pesto.

Salt and freshly ground black pepper To taste.

Instructions

Cook the shells

Bring a large pot of salted water to a boil. Add the shells and cook according to package directions until al dente, about 9‑11 minutes. Drain, reserving ½ cup pasta water, and set aside.

Pro Tip: Toss the hot shells with a drizzle of olive oil to prevent sticking.

Blend the pesto

In a food processor combine spinach, pine nuts, garlic, Parmesan, and olive oil. Pulse until coarse, then add cream and pulse again until the mixture is smooth yet still has a slight texture. Season with salt and pepper.

Pro Tip: Add the reserved pasta water a tablespoon at a time to achieve a silky consistency.

Combine pasta and sauce

Return the drained shells to the pot over low heat. Pour the creamy spinach pesto over the pasta, stirring gently to coat each shell evenly. If the sauce seems thick, stir in a little more reserved pasta water.

Pro Tip: Heat gently; boiling can cause the cream to separate.

Finish and serve

Remove from heat, drizzle with a final splash of olive oil, and sprinkle extra Parmesan if desired. Serve immediately while warm, accompanied by a simple green salad or crusty bread.

Pro Tip: Garnish with a few whole pine nuts for added crunch.

Expert Tips

Tip #1: Use Baby Spinach

Baby spinach wilts faster and blends smoother, giving the pesto a bright color without the fibrous texture of mature leaves.

Tip #2: Toast Nuts

Lightly toasting pine nuts (or walnuts) before blending deepens their flavor and adds a subtle nutty aroma to the sauce.

Tip #3: Adjust Consistency

If the sauce thickens too much, stir in a splash of milk, broth, or the saved pasta water until it reaches a silky pourable texture.

Storage & Variations

Store leftovers in an airtight container in the fridge for up to 3 days; reheat gently with a splash of milk to restore creaminess. Swap shells for rotini, add grilled chicken for protein, or replace spinach with arugula for a peppery twist.
