Why you will love this recipe

  • Sundried tomato pesto or red pesto is a fun twist on tradition pesto! The sundried tomatoes are bursting with flavor and they pair so well with pesto in this homemade red pesto sauce. After all, the only thing better than pesto is sundried tomato pesto!

How to make sun dried tomato pesto (red pesto)

  3. Check the consistency of the pesto, add water if needed.

How to make red pesto pasta

  1. Bring water to a boil (check out my tips on how to do this even faster below)
  2. Add the pasta and cook according to the directions on the bag/box.
  3. Right before draining the pasta, reserve about 1 cup of pasta water from the cooking liquid to help build the sauce.
  4. Drain the pasta, add it back to the hot pot.
  5. Add  the baby spinach and red pesto sauce to the pot with the pasta.
  6. Pour about ¾ cup of the reserved cooking liquid to the pot, focusing on wilting down the spinach. Stir well for about 1 minute to allow the water and the oil from the pesto to combine and emulsify into a thick, creamy sauce.
  7. Add up to ¼ cup more of the cooking liquid if you find it needs to be thinned out a bit.
  8. Taste for seasoning; add up to ¼ tsp more of salt to the dish (depending on how much spinach you added).

What you will need to make this recipe

What else can you add to this sun dried tomato pasta?

This spinach and sundried tomato pasta is perfect the way it is, but you could also add so other veggies or protein, if you want to make it even more filling. Some great options would be:

  • Broccoli florets (add to the boiling water when there is 1 minute left of cooking on the pasta)
  • Roasted cauliflower florets
  • Jarred or canned artichoke hearts, chopped
  • Roasted red pepper
  • Caramelized onions
  • Sautéed mushrooms
  • Cooked shrimp
  • Cooked, shredded or cubed chicken
  • Hemp hearts (for protein)
  • Chickpeas or white beans (for protein and fiber)

Time saving tips

The longest part of this recipe is waiting for the water to come up to a boil. If you have an electric kettle, fill it full of water and turn it on. While that is coming up to heat, also fill the large pot you are heating up with ½ the needed water and turn on high heat.

Once the kettle boiling, carefully pour it into the pot with the water that has been heating up. This will quickly increase the temperature of the water and help it come to a boil faster.

Take a few minutes to look at the cooking time of your favorite brands/shapes of pasta. Some cook faster than others. For example the red lentil pasta from Trader Joes cooks in just 5 minutes, where some of the chickpea pasta I have takes about 8-9 minutes.

Having a quick cooking pasta on hand can really make it easier to get dinner on the table fast.

What is the best pasta for red pesto pasta?

I like to use a pasta with lots of surface area to really collect all the red pesto sauce. I love a penne, casarecce, rotini, or elbow shape; but almost any shape will do!

You can also change up your dish with the type of pasta you choose! Some of my favorites are:

Lentil (my favorites are the Red Lentil Penne from Trader Joes and the Tolerant Brand as this is the most like regular pasta I have found)
Chickpea (I really like the Barilla pasta, and used the Casarecce shape in this recipe, but rotini would be great too)
Brown rice (my favorite is the brown rice penne from Trader Joe’s or the Jovial brand)
Sweet potato or butternut squash (great for Whole30 option)
Rutabega noodles (great for Whole30 option)

How to store red pesto pasta

This recipe will make 2 batches of the sundried tomato pesto. This pesto can be stored in the fridge for up to 2 weeks or stored in the freezer for up to 3 months. I like to freeze the pesto in silicone ice cube trays to make it easy to just use what you need later on. Once frozen, store them in an airtight bag with a label and a date.

Store any leftover spinach sun dried tomato pasta in the fridge for up to 4 days.

I would not recommend freezing the pasta as I don’t believe the pasta will have the right texture after freezing.

What to do with leftover sun dried tomato pesto

  • Use it as a topping for eggs or toast. Would be great on oven poached eggs or hard boiled eggs as well!
  • Top you favorite veggies (roasted, sautéed or steamed) with red pesto for instant flavor
  • Add a punch of flavor to your favorite meal. Serve over protein (chicken, shrimp, salmon, beans) for a super simple meal.
  • Serve on top of roasted potatoes or sweet potatoes


  • Sun dried tomatoes in oil: If you can only find sundried tomatoes that are dried in bags, you can reconstitute the tomatoes by soaking them in hot water for about an hour. Add the tomatoes, 2-3 tbsp of olive oil and 2-3 tbsp. of the water from soaking to the food processor in place of the sundried tomatoes in oil.
  • Basil: Traditional pesto uses basil, which I think pairs really well with the umami of the sun dried tomatoes. If you don’t have basil, you could try adding some flat leaf parsley, although the flavor will change some.
  • Cashews: You can also use hemp hearts or sunflower seeds to make it nut free or almonds, walnuts or pine nuts if you can have nuts.
  • Pasta: If you are using a non-traditional pasta like zucchini noodles, butternut squash noodles, sweet potato noodles or rutabaga noodles, you will need to add water to loosen up the red pesto sauce. You will want to add about ½ cup of hot water to start with, and I would recommend you combine the red pesto with the water separate from the noodles, so you don’t break the noodles from stirring so much.
  • Baby Spinach: You could also use kale (remove the tough stems), frozen spinach, or any of the veggies listed above.
