Ingredients & Preparation Notes
- Poblano Peppers: Roasting them brings out a deeper, smokier flavor. Choose firm, shiny peppers for the best results.
- Spaghetti: Whole wheat pasta adds more nutrients and fiber, but you can use any type you prefer.
- Olive Oil: Use extra virgin for the best flavor, but any type will work.
- Onion and Garlic: These aromatics form the base of the sauce, enhancing its overall flavor.
- Heavy Cream: For a lighter version, you can use half-and-half or even a milk and cornstarch mixture.
- Chicken Broth: Vegetable broth is a great substitute for a vegetarian version.
- Parmesan Cheese: Freshly grated cheese melts better and adds a nutty flavor to the dish.
- Salt and Black Pepper: Adjust to your taste, but remember that Parmesan is salty.
- Cilantro: Adds a fresh, herbaceous note to the finished dish.
Professional Tips & Techniques
- Roasting Peppers: Roasting poblanos at 400°F (200°C) for about 20 minutes ensures they blister and char, making them easier to peel and adding a smoky flavor.
- Pasta Water: Reserve some pasta water to adjust the sauce’s consistency. The starch in the water helps the sauce cling to the pasta.
- Sauce Simmering: Let the sauce simmer for at least 5 minutes to allow the flavors to meld and reduce slightly, creating a richer taste.
- Al Dente Pasta: Cook the spaghetti to al dente to ensure it holds up well in the sauce and doesn’t become mushy.
- Cheese Melting: Add the Parmesan off the heat to prevent it from becoming stringy or separating in the hot sauce.
- Visual Cues: The sauce should be thick enough to coat the back of a spoon but still flow smoothly when tossed with the pasta.
Recipe Variations
- Spicy Kick: Add diced jalapeños or a pinch of cayenne pepper for more heat.
- Protein Boost: Stir in cooked shredded chicken or shrimp for added protein.
- Vegan Option: Use cashew cream instead of heavy cream and nutritional yeast instead of Parmesan.
- Gluten-Free: Substitute with your favorite gluten-free pasta to make it suitable for those with gluten sensitivities.
- Herb Variations: Swap cilantro for parsley or basil for a different herbaceous note.
- Cheese Variations: Try using Pecorino Romano or a blend of Italian cheeses for a different flavor profile.
- Seasonal Twist: Add roasted corn or cherry tomatoes in the summer for a seasonal touch.
- Creamy Poblano Sauce: Blend the sauce until smooth for a more refined texture and presentation.

Poblano Spaghetti
Equipment
- Large pot for boiling pasta
- Baking sheet for roasting peppers
- Large skillet
- Tongs for tossing pasta
Ingredients
- 2 large poblano peppers roasted, peeled, and chopped
- 8 oz spaghetti preferably whole wheat
- 2 tbsp olive oil
- 1 small onion finely chopped
- 2 cloves garlic minced
- 1 cup heavy cream or half-and-half for a lighter version
- 1 cup chicken broth or vegetable broth for vegetarian option
- 1/2 cup Parmesan cheese grated, plus more for serving
- 1 tsp salt or to taste
- 1/2 tsp black pepper freshly ground
- 1/4 cup cilantro chopped, for garnish
Instructions
- Preheat your oven to 400°F (200°C). Place the poblano peppers on a baking sheet and roast them for about 20 minutes, turning halfway through, until the skin is blistered and charred. Remove from the oven, place in a bowl, and cover with plastic wrap for 10 minutes to steam. Peel off the skin, remove the seeds, and chop the peppers.
- Bring a large pot of salted water to a boil. Cook the spaghetti according to package instructions until al dente, about 8-10 minutes. Drain and set aside, reserving 1 cup of pasta water.
- In a large skillet, heat the olive oil over medium heat. Add the onion and sauté until translucent, about 5 minutes. Add the garlic and cook for another minute until fragrant.
- Stir in the chopped poblano peppers, heavy cream, and chicken broth. Bring the mixture to a simmer and let it cook for 5 minutes, allowing the flavors to meld together. Season with salt and black pepper.
- Add the cooked spaghetti to the skillet, tossing to coat the pasta evenly with the sauce. If the sauce is too thick, add some of the reserved pasta water to achieve the desired consistency.
- Remove from heat and stir in the Parmesan cheese until melted and well combined. Serve immediately, garnished with cilantro and additional Parmesan if desired.
