Ingredients
- 12 ounces spaghetti or similar pasta
- 3/4 teaspoon kosher salt for water
- 1 cup frozen peas
- 3 tablespoons cold unsalted butter, cubed
- 1/3 cup finely grated aged Asiago or Parmesan cheese
- 1 teaspoon preserved lemon zest or finely grated lemon peel, optional twist
- Freshly ground black pepper to taste
- Red pepper flakes, optional
About the ingredients
Method
- Fill large pot at least halfway with cold water; add salt when water is lukewarm enough. Bring to vigorous boil—the water must be roaring with bubbles that can’t be ignored.
- Add pasta, push gently down if needed, stir immediately to prevent clumps. Cook stirring occasionally. Watch pasta edges soften, test texture after 8-9 minutes. Al dente means some resistance, not chalk.
- While pasta cooks, dump frozen peas into microwave-safe bowl; cover with just enough cold water to barely swim. Microwave high 4-6 minutes, depending on wattage—less than 4? Extend time slightly. Listen for peas popping and water bubbling briskly; overcooked peas turn mushy, lose snap.
- Drain peas thoroughly in fine-mesh strainer. Let sit briefly to shed moisture; excess water dilutes butter later.
- Once pasta near done, reserve a half cup of starchy pasta water before straining pasta in colander. Drop spaghetti directly into large mixing bowl.
- Add butter cubes immediately—hot pasta melts butter unevenly creating silky spots and tiny lumps, rich aroma hits soft notes between savory and creamy.
- Stir in cheese and peas, add preserved lemon zest now if using to cut richness sharply with citrus tang.
- Use some reserved pasta water by tablespoon to help cheese and butter cling better if mixture feels dry or sticky.
- Taste. Adjust with cracked black pepper, maybe sprinkle red pepper flakes for a surprise bite.
- Serve freshly plated or warmed leftovers. Pasta firms quickly; reheat gently or add splash of water to loosen.
- Common pitfalls: Under-salting water leaves pasta bland. Too much peal water makes sauce watery. Overcooking peas ruins texture. Butter must be cold for better melt control; warm butter blends into a greasy slick.
- Substitutions: Regular frozen peas stand in for fresh with less cleanup, but fresh give brighter notes. Parmesan can swap with Pecorino Romano for saltier punch. Butter replaceable with olive oil for lighter mouthfeel, though reduces richness.
- You want pasta to cling to every pea, cube, and fleck of cheese, not swim in liquid. Efficiency trick: While water heats, prep peas to save minutes.
Cooking tips
Chef's notes
- 💡 Start with cold water in pot; salt early. It’s about seasoning base well; skipping salt ruins all. Watch water bubbles—once roaring, add pasta fast or starch mess starts. Stir immediately, push down gently if stuck. Don’t wait too long or clumps form. Test pasta edges and bite when cooking; soft around but with resistance.
- 💡 Frozen peas need timing. Microwave covered with just a splash of water; listen for popping and rapid bubbling. Less than 4 mins? Extend slowly; overcook and texture turns mushy quick. Drain well—wet peas water down butter, flatten texture. Peas should have snap, bright green color.
- 💡 Butter cold, cubed, added right into hot pasta. Melting unevenly makes richness spots, tiny lumps for texture. Warm butter blends into greasy slick; control melt speed by starting cold. Stir to break lumps but keep pockets. Aged sharp cheese joins immediately; toss gently, no grainy clumps. Cheese melts uneven, adds mouthfeel complexity.
- 💡 Preserved lemon zest is punchy contrast; add before tossing with water or after cheese. Cuts richness sharply, wakes palate. Use sparingly; too much overpowers. If no preserved lemon, fresh lemon peel finely grated works but milder. Keeps dish lively, brightens fat.
- 💡 Reserved pasta water is magic for cling. Use sparingly, tablespoon at a time; too much dilutes sauce fast. Texture shifts immediately; viscous last bit of starch binds cheese and butter to pasta and peas. Skip if sauce feels wet or mixture loses spots. Taste last, adjust pepper and decide on red flakes for heat.
Common questions
Why microwave frozen peas instead of boiling?
Microwaving uses less water, prevents water loss and nutrient drip. Controls time better; pops and bubbles tell cook doneness. Boiling risks overcook, mushy texture. Drain critical either way.
Can I use olive oil instead of butter?
Yes, but loses butter richness. Olive oil lighter mouthfeel, less creamy. Cheese and preserved lemon still add bite. Oil doesn’t create lumps or silky pockets; sauce more uniform. Adjust seasoning slightly because butter adds salt too.
How to avoid watery pasta sauce?
Drain peas fully, reserve minimal pasta water only. Too much starch water thins sauce; butter blends into slick. Butter cold helps control melt not liquid pool. Add water slowly; stop once sauce coats pasta and peas nicely.
How to store leftovers to keep texture?
Cool fast, store airtight. Reheat gently with small splash water to loosen sauce; avoid microwave overheat or sauce separates. Can also refresh on stovetop low heat, stirring often. Peas may soften but flavors last.
