How To Make Poblano Pasta

This whole sauce is sufficient for four serving, means to make 8oz pasta. I used less than half the quantity to make 4oz pasta with that.
Cook pasta as per instructions
While poblano peppers are roasting, cook spaghetti as per instructions, drain the water and run cold water on cooked spaghetti. This helps them not to stick with each other.
Boiling thin spaghetti pasta as per instructions
Do not forget to add salt to the water. Save ¼ cup of water in case you like to thin down the sauce further.
Assemble and serve
In a saucepan heat olive oil and add chopped garlic, cook it till the raw smell of garlic goes away. Switch off the heat and add red chili flakes and cooked spaghetti. Swirl around to coat it with oil. (pic 5-8)

I do not use pasta water in my recipe, as pesto sauce was thin enough to coat noodles evenly. But if required use ¼ cup of pasta water to thin out and mix.

Tips & FAQ’s
Should you heat pesto sauce?
Do not add pesto over the hot stovetop. Especially when basil involves, basil turns black in color if done so. This poblano pesto is already prepared by roasting peppers, so I did not find any color change while adding it or while reheating.
At the same time do not cook pasta after adding pesto sauce. Pesto with basil changes the color and texture if heated. Switch off the flame, add cooked pasta and finally add the sauce. Smear nicely and serve with favorite garnishing.
How to use pasta water to thicken the sauce?
Sometimes pesto sauce is very thick, adding pasta water helps in thinning out further. It helps in coating the pasta uniformly and adds flavors to it. It works as an emulsifier, starch from the water & oil works together to thicken the overall mixture. This is the only secret to making the best pasta that sticks with the pesto sauce.
What is the best pasta to cook with pesto?
Any pasta variety works well with pesto sauce. But short, textured pasta like elbow, penne, ziti works great as they hold the maximum sauce for flavors.
Personally, I liked the spaghetti pasta more as every string gets coated evenly and kids love to slurp. Though it is not easy to swirl around and mix with sauce. Bowtie pasta is also good comparatively.
How much pesto do you need to make pasta?
To make this 4oz thin spaghetti pasta I used less than half a cup of pesto sauce. However, this may change if using penne or ziti pasta. The key point is your pasta should be well coated, so be generous while adding pesto.
How To Serve
This recipe tastes great as is, but if required, add any roasted vegetables like broccoli, asparagus, or cauliflower. Or if you have a calorie surplus throw some roasted nuts like pine nuts, almonds, or cashews.
This is a great lunch/dinner recipe for meal preparation and makes ahead. Prepare the pesto sauce in advance and store it in an airtight mason jar. Cook pasta and store it in a separate container.
You just need to assemble these two at room temperature in order to prepare a quick fix.
How To Store
This cooked pasta can be stored in an airtight container for 2-3 days. Serve at room temperature or just reheat in the microwave for 30 seconds.
