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!

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!

Ingredients
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
Instructions
- 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.
- Make the linguine: Boil the pasta, according to the package instructions.
- 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.
- 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).
- 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.

YUM. this might be a stupid question, but for the jar of roasted peppers, are you supposed to include the liquid in it?
Sorry — drain the liquid!
I’ve updated the recipe to specify to drain the peppers. Great catch!
