Ingredients
- Good bread – sourdough or thick white for toasty crispness
- Mozzarella – fresh slices or shredded, super melty
- Tomato slices – ripe, juicy, and thinly sliced
- Avocado – soft and spreadable or sliced
- Butter or mayo – for that golden crust
- Salt & pepper – simple seasoning makes it pop
- Fresh basil (optional) – for a classic caprese vibe

How to Make It
Step 1: Prep the Ingredients
Slice the tomato and mozzarella. Scoop or slice your ripe avocado. Butter (or mayo) the outsides of your bread.
Step 2: Assemble the Sandwich
Layer mozzarella, tomato slices, and avocado on the inside of one bread slice. Sprinkle with salt, pepper, and fresh basil if using. Top with the second slice.
Step 3: Grill Until Golden
Place the avocado mozzarella and tomato grilled cheese sandwich in a skillet over medium-low heat. Cook slowly — about 4–5 minutes per side — until the bread is golden and the cheese is fully melted. Press gently with a spatula for even browning.
Step 4: Slice & Serve
Let it cool for a minute, then slice diagonally (because it’s cuter that way). Serve warm!
Pro Tips for Success
- Use low heat so the cheese melts before the bread burns
- Fresh mozzarella melts beautifully but may need blotting to avoid sogginess
- Ripe but firm avocado slices hold up better than mushy ones
- Salt the tomatoes lightly and let them sit to draw out extra moisture
- Press with a spatula for that panini-style finish
Flavor Variations
- Caprese Deluxe: Add a drizzle of balsamic glaze
- Spicy Kick: Add sliced jalapeños or chili flakes
- Extra Cheesy: Mix mozzarella with provolone or fontina
- Vegan Swap: Use dairy-free mozzarella and vegan butter
- Add Greens: Toss in a little arugula or spinach
Serving Suggestions
- Serve with a tomato soup or minestrone
- Pair with a simple arugula salad with balsamic dressing
- Cut into small squares for appetizer bites
- Great with fruit and sparkling water for a light lunch
Make-Ahead & Storage
Make-Ahead: Assemble the sandwich ahead and store in the fridge, wrapped tightly. Grill fresh when ready to eat.
Storage: Best eaten fresh, but leftovers can be stored in the fridge for 1 day.
Leftovers
- Reheat in a skillet for the best texture
- Chop and toss with a salad or use in a grain bowl
- Turn into a breakfast panini with a fried egg
Freezing
Not ideal — the avocado and fresh mozzarella don’t freeze well. Best enjoyed fresh or refrigerated for short term.
Reheating
Reheat in a skillet or toaster oven for crispiness. Microwave will make it soft but works in a pinch.
FAQs
Can I use shredded mozzarella instead of fresh?
Yes! Shredded mozzarella melts quickly and evenly.
What’s the best bread for this grilled cheese?
Sourdough is perfect — sturdy and flavorful. Thick white or ciabatta also work well.
Can I make it without butter?
Yes — use mayo on the outside for a crispy golden crust or brush with olive oil.
Is it good cold?
While best warm, avocado mozzarella and tomato grilled cheese can be eaten cold like a caprese sandwich — great for lunch boxes.

Final Thoughts
This avocado mozzarella and tomato grilled cheese is what grilled cheese dreams are made of — melty, fresh, creamy, and just the right amount of indulgent. It’s proof that comfort food can also be fresh, vibrant, and fast. Give it a try and see if it doesn’t become your new favorite sandwich!
