Roasted Tomato Sandwiches with Vegan Lemon Garlic Aioli
These Roasted Tomato Sandwiches with Vegan Lemon Garlic Aioli are loaded with avocado, arugula and some of the tastiest tomato slices.
Sometimes you just need a tasty sandwich that is simple and easy. And this sandwich is exactly that. It is basically avocado toast taken to the next level.
And just because it is simple to make doesn’t mean it is lacking in flavor. First let’s talk about the lemon garlic aioli.
How to make Roasted Tomato Sandwiches with Vegan Lemon Garlic Aioli
With just a few ingredients you are going to have the best sandwich spread EVER! Vegan mayo, lemon juice, salt, pepper and garlic are combined in a bowl and chilled until you are ready to eat. This stuff is finger-licking good.
The tomatoes are also simple to make (are you seeing the trend with this recipe?) but pack SO much flavor. I love when tomatoes are in season. They are so flavorful and sweet. So you best believe that tomatoes are going to be making a big appearance over the next few months here on TSV.
I, of course, chose sourdough for this sandwich – I mean, I can never get enough sourdough. You can use any bread you like, but I would choose something hearty so it can hold up with all of the toppings.
How to serve Roasted Tomato Sandwiches with Vegan Lemon Garlic Aioli
To get the sandwich extra toasty, you are going to slather some vegan butter on each slice and grill them in a pan before assembling. P.S. I personally love Earth Balance Butter.
To finish off this sammie, add some fresh basil leaves, arugula and avocado slices.
This sandwich is definitely not lacking in flavor. I could literally eat this every day!

These are absolutely delicious! I usually use lime instead of lemon and haven’t tried it with arugula yet. Either way, it has definitely been a stable in my lunch/dinner menu. Thank you!
I definitely meant to say staple! 😊
Are the calories listed just for 1 sandwich? Or for both? Thanks!
Hi Hannah – the nutrition is always listed per serving, so in this case it is just for 1 sandwich!
To make this a spread, should I put the aioli ingredients in a food processor? Because how else would you make it a smooth texture??
You can, but it isn’t necessary. I just combined the ingredients in a bowl.
I’m a non vegan and loved it! Making for 5 people next weekend as picnic. Any tips to packaging it all up? I can assemble when I get there.
Hi Dubs – I think your best bet is separate containers and wrapping the bread in parchment paper. Hope you all enjoy!
Absolutely delicious. The aioli is heavenly. As I was eating it, I was thinking that it would probably be delicious with some sauerkraut!
Ohhhhhhh yum…that sounds like a great add!
love this sandwich
Super tasty. Full of flavour. My only criticism is that it can be a bit messy with the tomato juices that come out once bitten into. I found cutting them in half prior to eating really helped it not be as messy. Absolutely delicious otherwise.
Delicious! So glad I’m not counting calories though. Fills you right up!
Haha – it’s all about balance anyways 😉
This was stunningly good! I actually “pressed” the tomatoes after roasting to limit the liquid which worked like a charm. Layered mayo/basil/tomato/arugula and mayo’d other side of bread and cut into threes. Was the “vegan” dish at an Italian themed luncheon and EVERYONE loved it – even the meat eaters!
Hi Kendall – so glad it was a hit!!!
Do you know around how many calories this would be?
Wow! First time trying vegan recipes. This sandwich was soooo DELICIOUS! First time trying sourdough and I’m definitely not a tomato person. I roasted them with lemon pepper seasoning and it really packed a flavorful punch! I also used spinach. New Favorite! Thank you!
Yay! So glad you liked it!
This was sooooooo good!!! I couldn’t eat it fast enough. I toasted the bread in a toaster oven with vegan butter on one side and the Mayo on the other. I added some onion flakes and seasonings to the Mayo. The roasted tomatoes were such a great idea. Certainly doing that again. Thank you for this awesome recipe. YUM!!
So glad you liked it! 🤗
Incredibly delicious! Made this for my family tonight and everyone loved it! It was so full of flavor! Even my husband, who is usually a meat & potatoes type of guy, raved about it. Thank you for a great recipe!!
Woowho – glad it passed the husband test 😉
This is such a delicious sandwich! I forgot the avocado and added fresh mozzarella. It was delicious! Making another one with avocado, right now. Can’t get enough of this sandwich lol THANK YOU!
You’re so welcome! So glad you liked it!
This is a delicious sandwich! I’ve made it several times for different people and it’s always a huge hit! I used thick slices of oven roasted heirloom tomatoes…Incredible!
We absolutely love this sandwich! We’re new to vegan/plant based foods, & we’re super excited to find this sandwich. We’re eating 2-3 times a week. I need to explore your website more. Thank you for sharing 😊
Yay! So glad you found a recipe to make your plant based journey easier! I hope you find more inspiration here 🙂
Delicious and a great summer dinner! Made some vegan mozzarella the other day so I put a little of that on too. Loved the combination of the aioli with the basil and arugula. Great recipe!!
So glad you liked it! And that mozz sounds like the perfect addition!
Hands down our new favorite sandwich. Made it twice this week and my husband is requesting roasted tomatoes on all veggie sandwiches going forward. Maybe a mexican version next, with cilantro and a cumin aioli? *drool*
Ummmmm…excellent suggestion. I actually have a recipe that has some mexican-flavors, I just haven’t put it on the blog yet. You have inspired me tho!
Will try this recipe one of these days.. This one looks delicious..
This recipe is AMAZING!!! My only note is to make sure you use a hearty bread. I used brioche this past time making it and it couldn’t withstand the moisture from the tomatoes. I ended up having to finish my sandwich with a fork! But oh man it was so good!
Made these last night for the first time. They are heavenly, so easy to make, and sooo fresh! These will be on rotation at our house this summer. I had to sub in spinach since I didn’t have arugula. Also made these on GF bread,
So glad you liked these – and you were able to adjust based on what you had on hand!
THIS RECIPE LOOKS SO GOOD. I can’t wait to try it! Do you think that balsamic vinegar drizzled would be a good addition or not?
I think that sounds super tasty!
Making these right this moment for breakfast sandwiches and the aoili ITSELF is a tasty dream! Because I’m 4 months pregnant with my first, this mostly vegan mom fried a free range egg to add to the middle, but this recipe is simple, beautiful, and a no-brainer. Thank you so much for making this for us! – Stay safe and healthy in the quarantine!
I had to make some modifications for what I had on hand but it was no less than spectacular!! Saw the recipe last night and knew it would be the perfect showcase for some nice heirloom tomatoes I had picked up. The aioli itself is amazing. No avacado so had to leave that out. Red leaf lettuce for the arugula. A++ and delicious!
Ugh – I love heirloom tomatoes! So glad you liked it!
So glad you enjoyed it! 🙂
Made these for dinner tonight. Added smoky tempeh strips and they were glorious!
Yum! That sounds like the perfect addition – I love tempeh bacon!
My husband and I made these for dinner last night. They were wonderful tasting and easy! Thank you!
You had me at roasted tomatoes and avocado! I made this for lunch today and it was delicious and easy to make. Thank you!!
So glad you liked this Brooke!
I’ve made these probably 3x a week for the past couple months. It’s an amazing combination of flavors and super simple to make. Love… and thank you for the recipe. ?
This is an amazing sandwich. The first time I made it, my daughter declared that it was the best sandwich she’d ever had. The lemon garlic aioli is fabulous and it’s all easy to put together. Thanks for sharing!
Just made these for dinner and OMG!!!! SO, SO good! I’m not vegan so I did use regular butter and regular mayo for the aioli, but other than that I followed the recipe. I’ve just sent the link to a bunch of family and friends because everyone needs to make them!
I just made these and ABSOLUTELY loved it. My meat eating husband even ate one and loved it too. I cheated and added a little parmesan and mozzarella for him
Thank you for sharing all these wonderful recipes.
Hey, it’s all about baby steps 🙂 Glad you both liked it!
Just made (& ate) this sandwich and it was so delicious! Will be making again 🙂
Yay! So glad you liked it! Nothing better than a good sammie 🙂
This was so simple and delicious! I used a ciabatta bread and did an open faced sandwich. I layered the mayo, arugula, avocado, pesto sauce and topped with the tomato. Perfect (end of the summer) sandwich.
Ugh…I LOVE ciabatta. That sounds amazing 🙂
I am not exaggerating when I say I eat this sandwich every single night for supper. I love it!! Its my absolute favorite recipe. Thank you for everything you do I have not tried a bad recipe yet from this site!
You’re so sweet Kat! And I am the same way. I will make something I really like, and eat it over and over. Don’t fix it if it’s not broken! lol
Just This sandwich was absolutely amazing! First meat free thing my husband would consider eating and it’s now his favorite. Instead of arugula and basil I just used baby spinach. I also put a bit of garlic powder in my vegan butter to spread on bread. I am obsessed, I already want it again!!!!
Yum! Those sound like awesome additions. Idk what it is about this sandwich, but you are not the first person to tell me that their meat-eating husband really liked this. lol. Must be the perfect combo of flavors so they don’t miss the meat 🙂
I just made this sandwich and it was SO SO GOOD! I can’t wait to have again!
Yay! So glad you liked it Nancy!
This is amazing! So easy to make and so satisfying
So glad you liked it – I love an easy recipe that is comforting at the same time 🙂
Just made this sandwich for dinner and it was hands-down one of the best things I’ve ever eaten! I used vegan basil pesto instead of plain basil leaves on one side and the aioli on the other. I would highly recommend that option. Thank you so much for the great post!! 🙂
Uhhhhhh…pesto sounds like the perfect addition! So glad you liked it!
Just finished these sandwiches! They were easy to make and so delicious! We will be making these again. Thank you!!
My carnivore husband said it was the best sandwich he ever ate.
That is amazing 🙂
Tomatoes are my fave fruit dressed up as a veggie. Yours is by far the best blog I have found for vegan dishes. After over 35 years as a vegetarian I made the switch 7 months ago. It wasn’t as big of a struggle as I would thought it would be as there’s lots of veganized items available – much more so than 15 years ago when I tried and failed. But seeing all your recipes is divine inspiration!
I’m so glad my recipes are making your transition easier! There really are sooooooo many vegan swaps these days – it’s kinda nuts! Happy cooking!
I didn’t have arugula but had fresh basil the last time I made these. WOW! I also used the microplane for the garlic. I now use this aioli on everything! I actually had a friend like it so much that I recycled an old ketchup bottle full of the aioli as a gift for her.
I am SO happy to have found this blog!
1- this sandwich looks aMAZing and I’m making it as soon as possible
2- all of your recipes make me want to cook, and I need some of that motivation in my life!
thank you thank you thank you.
You are so welcome – I’m glad my recipes gave you the cooking itch. 🙂 Can’t wait to see what you make!
