Instructions

  1. Step 1: Bring a large pot of heavily salted water to a boil. Add 12 oz spaghetti and cook for 8 minutes until al dente, reserving 1/2 cup pasta water before draining.
  2. Step 2: In a medium saucepan over medium-low heat, combine 1 cup whole milk, 2 tbsp unsalted butter, and 1/4 tsp salt. Warm gently for 3 minutes, stirring until butter melts and milk is just simmering—do not boil.
  3. Step 3: Add 2 minced garlic cloves to the milk mixture and cook for 1 minute until fragrant. Remove from heat and stir in 1/2 cup finely grated Parmesan until melted and smooth.
  4. Step 4: Return drained spaghetti to the pot, add 2 tbsp chopped parsley, and pour the sauce over. Toss with 2 tbsp reserved pasta water until the sauce coats the strands evenly and shimmers, about 1 minute.

Frequently asked questions

How long does Precision Parmesan Pasta take to make?

Total time is about 35 minutes (15 min prep + 20 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Precision Parmesan Pasta?

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 Precision Parmesan Pasta?

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 Precision Parmesan 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.

Italian pasta like this pair well with a simple grain (rice, couscous, or crusty bread), a quick salad with acid (lemon vinaigrette, pickled onions), and a pan sauce or yogurt-based dip. Tap "Plan a meal with the AI" to get specific side suggestions.
