Equipment You’ll Need For
Nothing fancy required here, just the basics:
- Kitchen knife – for slicing tomatoes and mashing avocado
- Small mixing bowl – for the avocado mash
- Toaster – for, well, toasting the bread
That’s the whole list. No food processor, no blender, no specialty gadget you’ll use once and forget about. Ever notice how the best recipes ask the least of you? This is one of them.
Why This Toast Works So Well
Heirloom tomatoes at peak ripeness genuinely don’t need much help. They’re sweeter, juicier, and more complex than standard supermarket tomatoes, and stacking them on creamy avocado lets that flavor shine without distraction. Add a drizzle of balsamic glaze and you get sweet, tangy, and creamy in a single bite.
I used to think avocado toast was overhyped just smashed avocado on bread, right? Turns out the details matter more than I gave them credit for. The lemon juice brightens the avocado, the basil adds a fresh herbal note, and the balsamic glaze ties the sweet and savory elements together. Skip any one of these and the toast falls a little flat.
This combo also happens to hit peak deliciousness during summer zucchini and tomato season, when heirloom varieties show up in every color imaginable. Ever tried a striped or purple heirloom tomato next to a regular red one? The flavor difference is honestly kind of wild.
The Ingredients Breakdown
Here’s exactly what goes into this toast:
- 1 small avocado (or ½ a large one)
- 1 medium tomato (or 7-10 cherry tomatoes if that’s what you’ve got)
- 1-2 squeezes of fresh lemon juice
- 1 pinch garlic powder
- 2 slices sourdough bread, or your favorite bread
- 2-3 leaves fresh basil
- A drizzle of extra virgin olive oil
- A drizzle of balsamic glaze
- 1 pinch kosher salt and black pepper, to taste
Heirloom tomatoes are the star here, so don’t skimp on quality. A bland, mealy tomato will drag the whole dish down, no matter how good your avocado is. FYI, most grocery store balsamic glazes are naturally vegan, but it’s worth double-checking the label if you’re buying a flavored or specialty version.
A Quick Word on Zucchini & Tomato Season
We’re deep into summer zucchini and tomato season, and this is genuinely one of the best ways to celebrate it. If you’ve got extra zucchini sitting around, thinly shave a few ribbons with a vegetable peeler and layer them under the tomato slices for some added texture and volume.
It’s not part of the original recipe, but it’s a small tweak that stretches this toast into something a little heartier without overcomplicating it. Is it necessary? Not at all. Does it make good use of the zucchini currently taking over your kitchen? Absolutely.
Step-by-Step Instructions
Let’s actually make this thing.
Step 1- Prep the avocado and tomato. Remove the skin and pit from the avocado, then slice your tomato. Mash the avocado in a small bowl until it reaches your preferred texture — chunky or smooth, whatever you’re into. Add the lemon juice, salt, pepper, and garlic powder, then mix everything together.
Step 2- Toast the bread. Toast your bread of choice until it’s golden and sturdy enough to hold toppings without going soggy. Nobody wants a floppy toast situation.
Step 3- Build the toast. Spread the avocado mixture evenly across each slice of toast. Layer the sliced tomatoes on top of the avocado, covering the surface as evenly as you can.
Step 4- Finish it off. Rough chop the fresh basil and scatter it over the tomatoes. Drizzle olive oil and balsamic glaze on top, then finish with an extra squeeze of lemon and a little flaky sea salt and black pepper.
Hint- If you want a deeper, sweeter tomato flavor, try roasting your tomatoes instead of using them raw. Slice them, lay them on a parchment-lined baking sheet, drizzle with olive oil, salt, and pepper, then bake at 400°F (200°C) for 20-25 minutes until softened and slightly caramelized.
Tips for Getting This Right Every Time
A few things I’ve picked up from making this toast more times than I can count:
- Use ripe, in-season tomatoes. This recipe has nowhere to hide flavor, so mediocre tomatoes make a mediocre toast.
- Toast the bread thoroughly. A soft, undertoasted slice will turn soggy the moment the avocado hits it.
- Season the avocado, not just the toppings. A bland avocado mash undercuts the whole dish, no matter how good your tomatoes are.
- Add the balsamic glaze last. It’s sweet and concentrated, so a little goes a long way — don’t drown the toast in it.
Storage & Make-Ahead Tips
This one’s really best enjoyed fresh. Avocado browns quickly once exposed to air, so I wouldn’t recommend making this ahead of time or storing leftovers. If you must prep ahead, store the mashed avocado separately with a squeeze of extra lemon juice pressed directly onto the surface, and assemble the toast right before eating.
Roasted tomatoes, on the other hand, hold up well in the fridge for up to 3 days, so feel free to roast a batch in advance if you’re using that method.

Frequently Asked Questions
Can I use regular tomatoes instead of heirloom? You can, but you’ll lose some of the depth and sweetness heirloom varieties bring. If heirlooms aren’t available, ripe vine tomatoes are the next best option.
Is this recipe gluten-free? Not as written, since it calls for sourdough bread. Swap in your favorite gluten-free bread and the rest of the recipe stays exactly the same.
Can I make this without garlic powder? Sure, though it does add a subtle savory depth to the avocado mash. Onion powder works as a decent substitute if you’re out of garlic powder.
What’s the best way to keep avocado from browning? Lemon juice helps, but the real trick is minimizing air exposure. Press plastic wrap or a bit of extra lemon juice directly onto the surface of the mash if you’re not eating it immediately.
