  • Total Time: 35 minutes
  • Yield: 4 servings

Ingredients

Peppers and Sauce

  • 1 lb poblano peppers (about 4 peppers)
  • 4 cloves garlic, roughly chopped (approx. 2 tbsp)
  • 4 oz cream cheese
  • 1/2 cup chicken stock
  • 1 bunch cilantro (3 oz), plus extra for garnish*
  • 1/2 cup heavy whipping cream
  • Salt, to taste

Pasta

  • 1 lb spaghetti
  • 1/4 cup butter, cut into pats (preferably salted)

Instructions

  1. Char the Poblanos: Place the poblanos directly over a gas stove flame or on a grill and char until blackened on all sides, about 10 minutes. Alternatively, place the peppers on a sheet tray under a high broiler, turning to ensure even blackening for roughly 10 minutes. Turn on the kitchen fan as the smoke can get quite strong.
  2. Steam and Peel: Transfer the blackened peppers to a bowl and tightly cover with plastic wrap. Let them sit for 5 minutes to steam, which softens the skin for easier peeling.
  3. Prepare the Peppers: Peel off the blackened skin, then remove seeds, stems, and visible ribs to reduce heat.
  4. Make the Sauce Base: Add the peeled poblanos, garlic, cream cheese, and chicken stock to a blender. Blend until smooth and creamy.
  5. Add Cilantro and Cream: Add cilantro (including stems without the bottom ends), heavy cream, and 1 tsp salt to the blender. Blend again and taste the sauce. Adjust salt as needed to ensure the sauce is well-seasoned.
  6. Cook the Pasta: Cook spaghetti in generously salted boiling water (salty enough to taste like ocean water) until al dente according to package instructions. Drain the pasta.
  7. Toss Pasta with Butter: Immediately toss the hot pasta with pats of butter until melted and noodles are well-coated.
  8. Combine Pasta and Sauce: Add the creamy green sauce to the butter-coated spaghetti and toss thoroughly. The sauce will thicken as the noodles absorb the liquid.
  9. Garnish and Serve: Garnish with additional chopped cilantro if desired and serve warm.

Notes

  • I include cilantro stems in the blender for extra flavor; just be sure to trim off the tough bottoms first.
  • Store leftovers in an airtight container in the refrigerator for up to 5 days.
  • Freezing is not recommended because dairy-based sauces and fresh cilantro lose quality and texture when frozen.
  • Reheat leftovers in the microwave covered to prevent drying out, starting with around 1 minute per serving and adjusting time as needed.
