Pesto Spaghetti with Roasted Tomatoes and Grilled Chicken


Isn’t pesto one of the best foods ever created? The flavor is so bold and vibrant, and when it’s homemade it’s just bursting with fresh flavor. It’s makes for one of the easiest and best pasta sauces, plus its healthy! Add it to spaghetti with some sweet roasted cherry tomatoes and some perfectly grilled chicken strips and you’ve got a meal worth remembering!

I was actually so surprised, I was planning on eating this pasta the next few days by myself. I didn’t think my husband would like it and I thought the flavors would be a little to fancy for my kids. They all loved it! My four year old was asking for more, and normally she’s the toughest critic for stuff like this. She’ll always say “I don’t like that green stuff, could you take it off please” whenever there is anything like spinach, basil, cilantro etc. Not this time and it was covered in green stuff :). Success!

I loved it so much I’m planning on making it again in the next few days! All the best Italian flavors in one delicious pesto spaghetti dinner. And you’ll love what the roasted tomatoes bring to this, it was hard for me not to eat them all straight from the baking sheet. Roasting veggies, or fruits in this case, always brings out the most irresistible flavors in them and it just brings out that delicious natural sweetness that sugar simply cannot duplicate.

Try this one soon, trust me you’ll love it!

  • Megan Childs: I made this for dinner and it’s being added to the recipe book. It delicious and my fiance loves it too! March 19, 2019 at 3:01pm Reply

  • Alina: Wonderful recipe. I went heavy on the garlic, and added walnuts instead of pine seeds. Loved the roasted cherry tomato kick as well! September 22, 2018 at 12:03pm Reply

  • Robin: I made this today. Although I loved it (hubs not so much, but he’s super picky), the small amount of pasta water really took away from the flavor of the pesto. I’ll probably make this again, but will definitely omit the water. I used whole wheat penne, and used seasoned, baked chopped chicken breast. Thanks for the recipe ????

  • Katherine Johnson: Another great dish from Cooking Classy. I am not a huge fan of tomatoes, but found I loved them roasted. Really good and really happy to add it to our approved dinner list. Thank you, Jaclyn!

    PS. If you have access to Trader Joe’s, they carry large boxes of basil. The plants just don’t provide enough…and I have tried!!! May 18, 2016 at 8:09pm Reply
