Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Cut tops off 2 whole garlic bulbs to expose cloves, drizzle with 1 tbsp olive oil, wrap in foil, and roast for 40 minutes until soft and golden.
  2. Step 2: Meanwhile, bring a large pot of salted water to a boil. Add 12 oz penne pasta and cook for 10-12 minutes until al dente. Drain and reserve 1/2 cup pasta water.
  3. Step 3: In a food processor, combine the roasted garlic cloves (squeezed out of bulbs), 1/2 cup toasted pumpkin seeds, 1 cup fresh basil leaves, 1/4 cup chopped fresh parsley, 1/2 cup olive oil, 1/2 cup grated Parmesan cheese, 1 tbsp lemon juice, 1 tsp salt, and 1/2 tsp black pepper. Pulse until smooth, adding reserved pasta water gradually to reach a creamy consistency.
  4. Step 4: Toss the cooked penne pasta with the pumpkin seed pesto until evenly coated. Serve topped with additional Parmesan and parsley if desired.

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 penne pasta from drying out.

Can I substitute ingredients in Roasted Garlic and Pumpkin Seed Pesto Pasta?

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 Roasted Garlic and Pumpkin Seed Pesto Pasta 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.
