Roast the poblanos. If using the (optional) jalapeños or serranos, roast those as well. You can roast them over direct fire (my favorite method) if you have a gas range or a fire pit. You can also broil them in the oven (for around 10 minutes) or set them directly onto a hot grill or pan (without oil). The goal is to quickly char and blacken the skin. Only char the skin. Don't burn the pepper inside. 4-5 Poblano Peppers, 1-2 Jalapeño or Serrano Peppers
Add the roasted peppers to a covered bowl to steam for 10 minutes.
While the roasted peppers steam, set a large pot of water to boil. Once boiling, add 1-2 Tbsp of salt and drop in your spaghetti. Cook per package directions.
1 Lb Spaghetti
When the peppers are steamed, remove the charred skin, seeds and stems.
Blend the peppers, onion, cilantro, crema, cream cheese, garlic, bouillon, and milk until smooth. This is your sauce.
1 Bunch Cilantro, 1/2 Medium Onion, 1 C Crema Mexicana, 8 Oz. Cream Cheese, 3-4 Cloves Garlic, 1 Tbsp Chicken Bouillon, 3/4 C Milk
When the pasta has finished boiling, reserve 1/2 C of the pasta water and strain it. Return it to the pot and stir in the butter to coat the pasta.
1 Tbsp Butter
Pour your sauce into a pot over medium-high heat and bring to a simmer, stirring occasionally. Season with salt and pepper to taste.
Salt and Pepper to Taste
Once the sauce is starting to bubble, combine it with the pasta. Check for thickness of the sauce. I like it to match a marinara sauce, but it is your preference. If too thick, add some of the reserved pasta water (1-2 Tbsp at a time). If too thin, let it cook for a minute or two.
Season one more time for salt and pepper, then serve topped with cotija cheese, cilantro leaves and maybe a slice of jalapeño or two.
