Roasted Red Pepper Pesto

Jump to Recipe

Some times when I am making my menu for the week, I get an idea for a particular flavor profile in my head. Sometimes it is really specific (though not all the time) and that is exactly where this recipe came from. I really wanted to make roasted red peppers myself, but I didn’t just want to add them to a plate. As I thought on it more, I came up with this Roasted Red Pepper Pesto to serve with some flavorful sausage and simple pasta.

You will definitely want a good food processor to make this sauce. Without one, you will have a hard time breaking the pistachios down far enough to not leave the sauce chunky, and not in a pleasant way. While pesto is not expected to a super velvety or silky sauce, it should however be a true sauce and not on the verge of being a salsa.

Not a lot of pesto recipes include pistachios as the nut component. A classic pesto is a basil and pine nut base with garlic, and parmesan cheese. However a pesto really just has to have a fresh herb and whole nut combination. So so use cashews, some use walnuts. Some add in other fresh herbs like parsley or oregano. I went with pistachios for this sauce because it actually has a very close taste to pine nuts (without the extra cost). Just be sure that you do not get any sort of seasoned or glazed pistachios, lightly salted is okay – but make sure you taste before you add more salt to the sauce.

You could use this sauce on a lot of different dishes – obviously a pasta dish would be the first choice. But it would make a delicious pizza sauce as well. You could put it in a grilled cheese with some steak, mushrooms and mozzarella. It would be awesome in a chicken wrap. Or you could do what we did with the little bit of leftover we had the last time I made it and use it as a dip with some pita chips.
