Why This Recipe Works

  • Using homemade basil pesto or storebought this recipe is full of flavorful herbs in every bite. You can use my homemade basil pesto recipe if you want. It’s a perfect solution for when the basil plants get large in summer and need to be used up.
  • Adding grape tomatoes (or cherry tomatoes) to the dish not only helps to add flavor and freshness but also helps to make the plates look incredible. You can use freshly sliced tomatoes or for more flavor, I suggest using roasted grape tomatoes- they’re seriously the best!
  • This pesto pasta with tomatoes uses sour cream with the noodles to help keep them moist and creamy. It also helps to prevent sticking, much like olive oil would do. The flavorful combination and texture really help to make this dish sing.
  • It’s fast and easy! This dish takes just 20 minutes to make from start to finish and is loved by humans of all ages. In fact, this is my kids most requested meal… they call it “green noodles.”
  • It’s easily customizable. You can add additional vegetables to this dish if you’d like such as sliced peppers or cucumbers and then top it off with chopped nuts. Or you can use kale pesto rather than basil pesto.

Recipe Tips

If you don’t wish to use the sour cream in this recipe you can simply use a splash of olive oil to help keep the pasta moist. You won’t get the same creamy effect, but you will cut down on some fats and still end up with a tasty dish.

You can use any pasta variety you wish. I personally opt for penne noodles but you can use long fettucini noodles, rigatoni, rotini, or whatever else you have on hand. Just cook them as directed for al-dente so they can hold up to the sauce and taste great. Cooking times will vary.

Adding cheese is optional but of course, cheese always makes meals like this taste even better. For a more flavorful experience, I recommend using freshly grated parmesan cheese over the top just before serving. Yum!

Adaptations: to make this a healthier pesto pasta recipe use plain Greek yogurt in place of the sour cream and add some lean protein such as cooked shredded chicken (rotisserie chicken) or grilled chicken.

FAQs

Can you use pesto straight from the jar?

Yes, this is the great thing about jarred pesto sauce is that it’s ready to use as soon as you pop the lid open. Use it in pasta recipes like this one or in other dishes too. It’s awesome and incredibly simple. Just make sure that once the jar has been opened, that you keep it stored in the fridge when not in use. This will extend the shelf-life and keep it safe for future consumption.

What is pesto made of?

Traditionally, pesto is made using a blend of fresh basil, garlic, salt, pine nuts, and parmesan cheese (or another hard cheese variety). To make it into a spreadable consistency it’s also given the addition of olive oil.

Can you reheat pesto pasta?

You don’t want to heat the pasta too much as cooking the basil in the pesto will cause it to lose flavor or even change colors. To safely reheat the paste to a warmer temperature place a portion on a microwave-safe plate and reheat until just warmed through. About 1-2 minutes. For large portions, place the pasta in a covered pot over medium to low heat and slowly reheat until it’s a little warmer than room temperature.

Pesto Pasta with Tomatoes

This Pesto Pasta with Tomatoes uses a few simple ingredients but packs a lot of flavor into every bite. This dish is a perfect meal to make any time of year but especially during the summer as it uses basil pesto and roasted tomatoes.
Prep Time: 10 mins
Cook Time: 10 mins
Total Time: 20 mins
Servings: 6 servings

Ingredients
 

  • 16 oz pasta - any noodle variety will do, I used penne
  • 1/2 cup sour cream - light or full-fat
  • 1/2 cup basil pesto
  • 8 oz mozzarella pearls
  • 1 cup grape tomatoes - fresh or roasted! (see notes), cut in half.

Instructions
 

  • Boil water in a medium saucepan. Add pasta. Cook according to package directions or until al dente. Drain the water and add the pasta to a large serving bowl.
  • To the pasta add the basil pesto, sour cream, mozzarella pearls, and grape tomatoes. Stir to combine. Season with salt and pepper to taste. Garnish with fresh basil and eat immediatly.

Notes

Noodles: use any noodle variety you like! 
Sour cream: this makes the pasta creamy. Feel free to use a full-fat sour cream or lite sour cream. You also have the option of eliminating the sour cream. If you choose to do this I suggest adding a teaspoon or two of extra virgin olive oil to the noodles to help keep them moist and not sticking together. For a healthier option you can substitute plain Greek yogurt for the sour cream.
Basil pesto: I have a delicious basil pesto recipe! You don’t have to use homemade pesto for this recipe. Any pesto brand will work well. 
Mozzarella Pearls: optional, but make this dish so yummy! If you add the pearls in while everything is nice and warm they melt slightly and it’s delicious! 
Tomatoes: feel free to use fresh grape or cherry tomatoes (I cut them in half to make them easier to eat), or roast the grape tomatoes and add the hot roasted tomatoes to the warm pasta dish. Oh my gosh, so yummy!!
Variations: can top with freshly grated parmesan cheese.
