Ingredients

Instructions

  1. Step 1: Bring a large pot of salted water to a boil. Add 8 oz spaghetti and cook for 8 minutes. Add 2 cups broccoli florets to the pot and cook together for 3 more minutes until both pasta and broccoli are tender. Drain and reserve 1/2 cup pasta water.
  2. Step 2: Meanwhile, heat 3 tbsp olive oil in a large skillet over medium heat. Add 4 minced garlic cloves and 1/4 tsp red pepper flakes (if using), sauté for 30 seconds until fragrant — do not brown the garlic.
  3. Step 3: Add the drained pasta and broccoli to the skillet along with 1 tsp lemon zest, 2 tbsp lemon juice, 3/4 tsp salt, 1/4 tsp black pepper, and 1/2 cup reserved pasta water. Toss vigorously for 1-2 minutes until the sauce slightly thickens and coats the pasta.
  4. Step 4: Remove from heat and stir in 1/4 cup grated Parmesan cheese until melted. Serve immediately.

How do I store leftover Lemony Broccoli and Garlic Spaghetti?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep spaghetti from drying out.

Can I substitute ingredients in Lemony Broccoli and Garlic Spaghetti?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Lemony Broccoli and Garlic Spaghetti for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
