One half has three bright red tomato slices layered neatly on top of what looks like white cream or spread on a slice of toasted bread. The other half features a layer of fresh green lettuce topped with thinly sliced light green avocado, arranged in a neat row on another toasted slice of bread. The plate sits on a white marbled surface, next to a white bowl filled with green leafy salad and a smaller white bowl with creamy dressing and a spoon inside.

How to Make Roasted Tomato Sandwiches with Vegan Lemon Garlic Aioli Recipe

Step 1: Roast the Tomatoes

Start by preheating your oven to 350 degrees Fahrenheit and lining a baking sheet with parchment paper to prevent sticking. Arrange your sliced tomatoes on the tray and drizzle them with olive oil. Then, sprinkle salt, pepper, and dried oregano evenly over each slice. Pop them into the oven and roast for about 15 to 20 minutes until they soften and their flavors intensify with a slight caramelized edge. Roasting really brings out the depth in these tomatoes, turning them into juicy, sweet bites that become the sandwich’s star.

Step 2: Prepare the Vegan Lemon Garlic Aioli

While your tomatoes are roasting, whip up the vibrant vegan lemon garlic aioli. In a small bowl, combine vegan mayo, freshly squeezed lemon juice, diced garlic, and a pinch of salt and pepper. Give it a good mix until smooth and creamy. Taste and adjust the seasoning, adding more lemon juice if you want extra brightness or garlic for a little more punch. Pop this in the fridge to chill and let those flavors meld while you prepare the rest.

Step 3: Toast the Bread

Spread vegan butter on one side of each slice of sourdough bread. Heat a skillet over medium heat and place the bread butter-side down in the pan. Cook until the bread turns golden brown and slightly crispy — it should have a wonderful crunch to balance the softness of the fillings. Remove from heat once toasted to perfection.

Step 4: Assemble the Sandwich

Now for the fun part: layering your masterpiece. Spread a generous amount of the chilled lemon garlic aioli on each piece of toasted bread. Add the roasted tomato slices first, then layer creamy slices of avocado on top. Scatter fresh arugula and fragrant basil leaves generously. Close your sandwich with the other slice of bread, and slice it diagonally for that classic deli-style look.

Behind the sandwich, a white bowl filled with fresh greens and some green leaves are placed on a white marbled surface. A woman's hand is partially visible near the sandwich.

Garnishes

To make these sandwiches even more inviting, consider garnishing with a few fresh basil leaves or a sprinkle of cracked black pepper on top. A light drizzle of extra virgin olive oil or a few chili flakes can add exciting little bursts of flavor if you’re feeling adventurous.

Side Dishes

This sandwich pairs wonderfully with crisp, crunchy sides like a fresh cucumber salad, baked sweet potato fries, or a simple green salad dressed with lemon vinaigrette. These sides keep the meal light and fresh while complementing the sandwich’s bright, rich flavors.

Creative Ways to Present

For a charming twist, cut the sandwiches into smaller, appetizer-sized pieces and serve on a wooden board with toothpicks. Alternatively, layer the ingredients inside wraps or baguettes for an on-the-go option that still boasts the vibrant flavors of the original. Presentation makes it feel extra special and perfect for sharing at gatherings.

Make Ahead and Storage

Storing Leftovers

If you have leftovers, keep the sandwich components separate to avoid soggy bread. Store roasted tomatoes and aioli in airtight containers in the fridge for up to three days, and keep avocado and greens fresh by adding them just before serving.

Freezing

This sandwich is best enjoyed fresh, especially because the avocado and arugula don’t freeze well. However, you can freeze the roasted tomato slices on their own for up to two months in a freezer-safe container to save time on future sandwiches.

Reheating

To reheat leftover roasted tomatoes, gently warm them in the oven or on the stovetop until heated through. Toast fresh bread and spread the chilled lemon garlic aioli again before assembling for maximum freshness and flavor.

FAQs

Can I use other types of bread for this recipe?

Absolutely! While sourdough is perfect for its texture and slight tang, you can use whole grain, ciabatta, or even a crusty baguette. Just make sure the bread is sturdy enough to hold the juicy fillings.

Is the vegan lemon garlic aioli difficult to make?

Not at all! It’s actually a super simple mixture of vegan mayo, lemon juice, garlic, and seasoning. It comes together in just minutes but adds incredible brightness and depth to your sandwich.

Can I add other veggies to the sandwich?

Feel free to get creative! Sliced cucumbers, roasted peppers, or even thinly sliced red onions would all add wonderful crunch and flavor to the sandwich.

How do I ensure the tomatoes roast evenly?

Make sure the tomato slices are roughly the same thickness and spaced out on the baking sheet so they roast rather than steam. Drizzling them with olive oil also helps them caramelize nicely.

What if I don’t have vegan mayo on hand?

You can substitute with store-bought or homemade cashew cream or even mashed silken tofu mixed with some lemon juice, garlic, and a pinch of salt for a similar creamy base.
