Looking to give your lunch routine an upgrade? Try my favorite avocado sandwich recipe! With creamy avocado, roasted tomatoes, and a spicy mayo, it’s the perfect combination of flavors and textures.

Years ago I had an amazing sandwich that I’ll never be able to remember everything on it, but one thing stood out, the pickled onions on the charred tomatoes made a magical flavor I never would have expected. This sandwich gives a nod to not only that sandwich but the perfection that comes when you have a perfectly balanced sammy with sweet, salty, crunchy, acidic, toasted and… AVOCADO.

Lately our daughter has been loving avocado toast and so we took the best of her toast discoveries at restaurants with my sandwich memory and created literally the best avocado sandwich ever.

The measurements and details for each ingredient can be found in the recipe card down at the end of this post.

Claire’s Tip

To find the perfect avocado, use your thumb and forefinger to gently press the top and bottom of the avocado. It should give a little if it’s ready to go. Never press or palm the whole fruit as it will bruise it.

What is the Best Bread for This Sandwich?

My favorite bread for this sandwich is the seven grain bread from Harmon’s here in Utah. In all reality, you could use any type of bread that you want…a multigrain bread, a good whole wheat bread, or heck, even a yummy white bread works great! Ooh, or sourdough bread! I’m trying that next time!

How to Make an Avocado Sandwich

Before you start to make this sandwich, make sure your red onions are pickled and you’ve whisked together the ingredients for the spicy mayo in a small bowl. Here are the steps for each fabulous layer…

Char the Tomatoes: Heat the oven to broil and place the tomatoes on a baking sheet, cut side down. Move the oven rack to the highest position and place the baking sheet in. Keep a close eye on them and cook only until the tomatoes begin to char then remove from the oven.
Toast the Bread: Toast the bread slices. You can either use a toaster or stick them in the broiler with the tomatoes. Butter one side of each slice of bread.
Assemble the Sandwich: Spread the other side of each piece of bread with the spicy mayo. Add the cheese then the tomatoes, sprouts, micro greens and arugula. Finally add the sliced avocado (you could also mash the avocado with a fork and spread it on) and pickled onions, then sprinkle with salt and pepper. Top with another slice of bread.

Carrian’s Notes

You MUST salt and pepper the tomatoes and avocados. It will make all the difference to have a seasoned sandwich. Actually, I think sprouts and microgreens are a must too. Their flavor and texture are game-changers!

What’s the Difference Between Young and Old Manchego?

How long Manchego cheese has aged will greatly affect the flavor of the cheese. Young Manchego cheese has a more mild taste and more creamy texture. Old Manchego has a more bold and nuttier flavor. It is also more firm in texture. I love young for sandwiches and old for salads.

Substitutions and Additions

If you aren’t a Manchego cheese fan, some great substitutes would be havarti or feta cheese.

Some other options for substitutions would be sun dried tomatoes instead of the charred tomatoes, pickles instead of the pickled onions, or any fresh salad greens or spinach for the arugula and microgreens.

You could use lemon juice or pickle juices if they aren’t doing the pickled onions though it will be a mistake because even I LOVED the balance they brought to the dish and I’m not usually an onion on a sandwich gal.

For a heartier sandwich, add some slices of roasted good quality turkey that you get from the deli! Some crispy bacon would also be delicious!

Honestly, I would try it once without making substitutions. It’s that good!

What to Serve with Avocado Sandwiches

A sandwich for lunch usually doesn’t need much, if anything, to go with it. Some carrots or a sliced apple would be perfect alongside it. If you’re serving this sandwich for dinner, you could add a side salad, vegetable, or cup of soup with it. Here are a few ideas:
