As if roasted tomato crostini aren't good enough on their own. Add some smashed avocado and basil for your new favorite summertime appetizer.
Roasted Tomato Crostini with Avocado
Roasted tomato crostini embody everything that's right with summertime. They highlight fresh seasonal produce, they're a breeze to make (cue the carefree summer living vibes) and they're ideal for sharing with friends while sitting on the patio, glass of blackberry iced tea or raspberry mojito in hand.
And if you've ever tasted roasted tomatoes, you know that nothing can beat that smoky sweet flavor. When made with cherry or grape tomatoes, they're like little jewels that explode with flavor as you bite down. And I promise that your kitchen will smell like a nonna's kitchen in the heart of Tuscany. Roasted garlic and veggies emit the most ethereal aroma that you'll want to recreate day after day.
Roasted tomatoes are a breeze to make and they are the star of this vegan crostini recipe. As tempting as it will be to eat the tomatoes straight off of the baking sheet, take a few extra minutes to toast some baguette slices and mash some avocado with lemon juice. The result is a fresh, healthy appetizer that will likely become your summer fallback recipe.
How to roast tomatoes:
- Start by with a hot oven - 400 degrees F will do the trick.
- I recommend lining the baking sheet with foil for easy clean-up. Parchment paper or a silicone baking mat (affiliate links) are also good options.
- If using grape or cherry tomatoes, place them in a bowl and toss with olive oil, salt and pepper, then transfer to the lined baking sheet. If using sliced tomatoes, arrange them in a single layer on the baking sheet and drizzle with olive oil, then season with salt and pepper.
- Roasted tomatoes are made even better with the addition of garlic, but this is optional. When adding garlic, do so in the second half of cooking the tomatoes so that the garlic doesn't burn. Roast the tomatoes for 10 minutes, then add the garlic and roast for an additional 8 to 10 minutes, or until the tomatoes are tender and starting to burst.
Tips for making these roasted tomato crostini:
- Start by slicing the baguette and toasting the slices on a baking sheet in an oven set to 350 degrees F. It should take about 5 minutes to lightly toast the baguette slices. This can be done up to a few hours ahead of time. If you're not using the baguette toasts right away, let them cool completely, then transfer to an airtight container. If they are still warm when you close the container, steam will accumulate and the bread will soften.
- Roast the tomatoes according to the directions above (or in the recipe below).
- While the tomatoes are roasting, smash the avocado with the back of a fork and mix in some fresh lemon juice, salt and pepper. The lemon juice will help to keep the mashed avocado nice and green, as it slows down the oxidation process.
