INSTRUCTIONS
 

Step 1: Cook the Pasta

  • Bring a large pot of salted water to a boil.
  • Add 12 oz spaghetti (or preferred pasta like fettuccine, linguine, or penne).
  • Cook according to package instructions until al dente (firm but tender).
  • Reserve ½ cup of pasta water, then drain and set aside.

Step 2: Prepare the Creamy Poblano Sauce

  • Blend together:
  • Roasted poblano peppers
  • ½ cup milk (whole or evaporated)
  • ½ cup heavy cream (optional for extra richness)
  • 4 oz cream cheese (for a silky, creamy texture)
  • 2 cloves garlic (minced)
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon cumin (optional, for warmth)
  • ½ teaspoon chicken bouillon powder (optional, for depth)
  • ¼ cup fresh cilantro (optional, for herbal freshness)
  • Blend until completely smooth and creamy.
  • Taste and adjust seasoning if needed.

Step 3: Cook the Sauce & Combine with Pasta

  • In a large skillet, melt 1 tablespoon butter over medium heat.
  • Pour in the blended poblano sauce and cook for 3–4 minutes, stirring occasionally.
  • Add the cooked pasta to the skillet and toss gently to coat each strand in the sauce.
  • If the sauce is too thick, add small amounts of reserved pasta water until you reach your desired consistency.

Step 4: Serve and Enjoy

  • Divide the Green Spaghetti into serving plates.
  • Sprinkle with crumbled queso fresco, grated Parmesan, or Cotija cheese for extra flavor.
  • Garnish with fresh chopped cilantro or a squeeze of lime juice for brightness.
  • Serve hot with garlic bread, grilled chicken, or roasted vegetables.

NOTES

Pro Tips for the Best Green Spaghetti
  • Roast poblanos properly to bring out their smoky flavor—don’t skip the steaming step for easy peeling.
  • Blend the sauce until completely smooth for the creamiest texture.
  • Reserve some pasta water to adjust the sauce consistency if it becomes too thick.
  • Use evaporated milk instead of regular milk for a richer, creamier sauce.
  • For extra heat, add a serrano or jalapeño pepper when blending the sauce.
  • Serve immediately for the best taste, but if reheating, add a splash of milk or broth to keep it creamy.
By following these tips, your Green Spaghetti will turn out smooth, flavorful, and restaurant-quality every time!
