We haven’t been this excited about a dinner recipe in a long time.
Probably not since the 15 Minute Creamy Avocado Pasta, which Eric said – in between shoveling this pasta in his mouth – is “not as good as this roasted tomato pesto recipe”.
I didn’t believe it, but after tasting and then devouring my own bowl of pesto (ok, there was some pasta in there too), I may have to agree with him. This is by far, the best pesto I’ve made or perhaps ever tasted.
Don’t be put off by the colour, I promise it tastes much better than it looks. ;)
We enjoyed it so much, I made two batches over the long weekend and froze some for a later date. In January, there will be no tears over tasteless tomatoes as long as I have this pesto waiting for us!
If I can wait that long to eat it, that is.
Outlook not good.

Roasted Tomato Basil Pesto Pasta
This pesto is bursting with seasonal flavours and nutrients. Hello lycopene! It’s also quite low in oil thanks to the roasted tomatoes adding body and flavour. I left the almonds chopped and it added a nice texture that was great mixed into pasta or spread on a toasted sandwich. I suggest making some and freezing it for a later date.
Inspired by Gourmet.
Yield: 1 cup pesto
Ingredients:
- 9 large roma tomatoes, sliced in half lengthwise
- 1/2 cup almonds, toasted
- 2 garlic cloves
- 1 cup tightly packed basil + more for garnish
- 1/4 cup extra virgin olive oil + more for drizzling on tomatoes
- 2 tbsp nutritional yeast (optional)
- Kosher salt & freshly ground black pepper, to taste
- Your desired amount of cooked Pasta
1. Preheat oven to 400F and line a baking sheet with parchment. Place sliced tomatoes on the sheet and drizzle with oil, salt, and pepper. Roast for about 1 hour and 10 mins at 400F. Watch closely during the last 15 minutes of roasting.
2. Reduce oven heat to 325F and toast almonds for 8-10 minutes. Add 1/3 cup into food processor and process until finely chopped. I left mine a bit chunky for texture. Remove and set aside.
3. With processor turned on, add 2 garlic cloves and let it whirl around until finely chopped. Now add in the basil and process until finely chopped.
4. Add in the oil, optional nutritional yeast, and 1.5 cups of roasted tomatoes (you will have tomatoes left over). Process until smooth. Pulse in 1/3 cup toasted almonds. Season generously with salt and pepper. I think I used about 1/2 tsp salt or a bit more.
5. Pour your desired amount of pesto over the cooked pasta and mix well. Chop the remaining roasted tomatoes and stir into pasta. Chop remaining almonds and Chiffonade the basil (see below).

I decided to roast the tomatoes first to give the pesto a really deep flavour. So glad I did!!
First, I drizzled them with olive oil and sprinkled them with kosher salt and freshly ground black pepper.
Into the pre-heated oven they went at 400F for about 1 hour and 10 minutes. The longer they roast, the more delicious they become. The bottoms will be blackened slightly, but not to worry as it only enhances the flavour.
After cooling slightly, I ate one straight off the pan. And I almost burned my mouth off, but it was so worth it. I’m surprised that the rest of them made it into the processor!
While the processor blade is spinning, add two garlic cloves. Let it whirl around until the garlic is chopped. Next, add 1 cup of tightly packed basil and process. Scrape down the sides of the bowl with a spoon. With the processor on, add in 1/4 cup oil, 1.5 cups of roasted tomatoes, nutritional yeast (optional), and salt and pepper to taste. Pulse in the toasted almonds.
I’m loving this olive oil right now:
This pesto is so delicious it’s unreal.
This was my first batch and I used 1 cup of roasted tomatoes, but I suggest using 1.5 cups of roasted tomatoes as I did in my second batch. You get more bang for your buck!
If you want to be a fancy pants, you can Chiffonade the basil for garnishing on top of the pasta. “Chiffon” is French for “rag” which is what the basil will look like when you’re finished.
How to Chiffonade basil:
1. Grab a few basil leaves (you can use spinach or any leafy vegetable for future reference)
2. Stack them on top of one another like so.
3. Now roll it up all the way.
4. Grab a sharp knife and slice tiny 1mm cuts through the rolled up basil.
Do not slice finger off as it looks like I’m about to do in the above photo. That would not be good.
Repeat until you’ve sliced through all of it. The basil, not your finger.
5. With your (in tact) fingers, gently separate the basil into its ‘rag-like’ pieces and sprinkle over top of your dish.
And if you handle them as long as I did to get these photos, they will really look like rags!
You are now a fancy pants.
It is your mission to go on and enjoy those deliciously sweet tomatoes that are waiting for you.
Just don’t forget to freeze some for the Winter!








What can I sub for the nuts? I would love to make this but am allergic!
Im not sure, do you think sunflower seeds would work?
This was soooo good, loved it.
I made an awesome pasta salad with your delicious roasted tomato pesto! I added diced zucchini, red onion, black olives, and capers. So good! Thanks for another great recipe. :)
I’m about to make this! If I were to do this with cherry tomatoes, how many cups would I use?
I had an overflow of Roma tomatoes and basil from my garden and decided to make a double batch of this. I am SO glad I did, it is delicious!
Oh My, this sounds and looks delicious… And I love the name of your website! :))) Shine On!!!
WOW! WOW! WOW! I just made this and put it over raw zucchini and yellow zucchini pasta. I’m in love. Lol.
Ange – Fantastic! Made this for the kids tonight and I was blown away! What an incredible flavor combo!!!! You’re the best!!
I second dhauberger’s scentiment!
JusT an FYI. I am making this right now & threw in some more beefsteak type heirloom black tomatoes in addition to Romas because I have a bunch as well. They roasted down to practically nothing so probably best to stick with romas.
Aw good to know, thanks for the tip! Sorry that happened to you.
I made this for dinner tonight with a non-vegan – we both LOVED it, sooo good and sooooooooooo easy!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you!!
Can’t wait to serve this tonight…just put the tomatoes in the oven to roast.
I do have a question, I have not used nutritional yeast before. I did purchase some in bulk to try. Do you know by chance the salt content?
Thanks for sharing this recipe!
How many tomatoes do you think you,d use if you have big beefsteak tomatoes? It’s hard to tell how many tomatoes are equivalent to 9 Roma’s, but it looks like 1.5 cups total?
Hey Emily!
I’m sorry I didn’t measure the amount of cups prior to roasting (should have or weighed them). Anyway, the tomatoes do shrink down when roasting, so I would err on the side of roasting too many rather than too few – the leftover are AMAZING thrown into pasta, salads, etc. Goodluck!
This recipe is amazing! I love that it used up so many of the Roma’s sitting on my kitchen window sill.
Just thought I would comment since I just made this for dinner tonight as I had a whole bunch of heirloom tomatoes to use up from my CSA box. I’m eating it right now and it’s delicious! I threw in some hot pepper flakes to spice it up a notch. Thanks for the simple, yet tasty recipe.
Made this and it was absolutely fantastic. Took your hint and made extra to freeze. Love your site.
I made this again last night as part of an unprocessed dinner. I think it is delicious. One question I have is have you ever made your own vegan pasta? If so do you have a good recipe you could share?
WOW!!! I made this dish last night — soooo freakin good I couldn’t believe it. I’ve never made pesto or roasted tomatoes or almonds before, and boy oh boy my mouth is in love. Can’t wait to make it again! Thank you so much for this delicious recipe :)
This looks fantastic! I was wondering if it would be okay if I used one of your photos for this recipe and linked to your blog through my own. I’m doing an event for my upcoming, golden, 18th birthday and I am having a huge event called “Shinmas” where I am advertising other people’s blogs and we have a whole setup of themes each day and it becomes really fun. I am also going to hold a few giveaways so that those who don’t have blogs or artwork to share can also join in.
Thank you for your time,
Bou Shin
Thanks for asking. That is not a problem – please email me the link when it’s up! press[at]ohsheglows[dot]com
This is absolutely delicious! I have tonnes of tomatoes from my garden that are ripening rapidly, this is the perfect recipe for them. I’m going to make more batches to freeze. Thanks for the wonderful recipe!
