This red pepper pesto features roasted peppers, sundried tomatoes, and walnuts, blended together to form a firey red pesto. It’s perfect as a pasta sauce!

Red Pepper Pesto Pasta

Here’s a pasta recipe we dreamed up with a zesty red pepper pesto sauce. The pesto we adapted it from our own Roasted Red Pepper Pita Pizzas recipe — it’s an interesting alternative to a tomato-based sauce. We added some kale for some nice nutrients and a bit of texture. Paired with salty feta and crunchy walnuts, it’s a delicious and fancy-looking entree! Keep reading for the recipe.

How to make red pepper pesto

This red pepper pesto is incredibly easy to make! You’ll need a food processor to whip this one up. The red peppers we’re using here are roasted red peppers, from a jar. You can usually find roasted red peppers in the grocery near the olives and canned artichoke hearts. To bring in a depth of flavor, we’re also using sundried tomatoes. Look for sundried tomatoes packed in oil, versus straight up dried tomatoes. These should be available in a similar place in the grocery store.

This one takes literally 5 minutes to make: just whiz up the roasted red peppers with sundried tomatoes, walnuts, olive oil, and salt. It makes a firey red pesto that’s perfect on pasta or pizza!

How to serve this red pepper pesto

Here we’re using this red pepper pesto as a sauce for linguine, which we accessorized with chopped sauteed kale. It’s sprinkled with feta cheese for a little savory hint. If you’d like, toast some walnuts in a skillet and sprinkle them over the top too. It adds a nice crunch: but it’s also not necessary if you’re in a time crunch!

Red Pepper Pesto Pasta

  • Author: a Couple Cooks
  • Prep Time: 15 minutes
  • Cook Time: 15 minutes
  • Total Time: 30 minutes
  • Yield: 4 to 6 1x


This red pepper pesto features roasted peppers, sundried tomatoes, and walnuts, blended together to form a firey red pesto. It’s perfect as a pasta sauce!



For the red pepper pesto

  • 12-ounce jar roasted red peppers
  • 12 sundried tomatoes packed in oil
  • 1 tablespoon olive oil
  • ½ cup walnuts
  • ½ teaspoon kosher salt

For the linguine

  • 1 bunch Tuscan kale
  • 1 tablespoon olive oil
  • Pinch red pepper flakes
  • 1 pound whole wheat linguine
  • ½ cup walnuts (optional)
  • 4 ounces feta crumbles


  1. Make the red pepper pesto: Drain the jar of red peppers. In a food processor or blender, combine the roasted red peppers, sundried tomatoes, olive oil, walnuts, and kosher salt.
  2. Make the linguine: Boil the pasta, according to the package instructions.
  3. Chop the kale. In a large skillet, heat the olive oil and add the red pepper flakes. Add the kale, then saute until just wilted, about 3 to 4 minutes. Stir in a pinch of kosher salt, then remove from the heat.
  4. Toast the walnuts (optional): In a dry skillet, toast about the walnuts over medium heat, stirring often, until the nuts are fragrant and toasted, about 3 to 4 minutes (be careful that they do not burn).
  5. When the pasta and kale are done, add the kale to the pasta. Mix as much pesto as desired into the pasta (you may have to taste and adjust quantities). Top with toasted walnuts, feta crumbles, and a bit of olive oil.

  1. Happy belated birthday! This looks delicious!

    “bouncing from one thing to the next, trying to understand where to direct my passion as it spewed everything in its path.”

    This really hit home for me. I’m so glad you were able to direct your talents and passion in a way that did so much good for so many. You should really be proud; what a great way to begin your 30’s. You rock!

    1. Thank you so much, Meghan! That is so sweet of you to say! I am glad to know there are others who can identify with the struggle in the search for finding your calling/passions. Best of luck to you on your journey too!

  2. Pasta is definitely my weakness. And this looks delicious! Roasted Peppers and Feta are so yummy together. Gorgeous photo! :)

  3. This came at the absolute perfect time! I didn’t menu plan or grocery shop this week because of Courtney’s surprise visit, but I did get two red peppers in my green bin and was trying to decide on a use for them. This sounds amazingly delicious! Trying it ASAP.
