This tuna melt sandwich recipe is the perfect simple lunch that still tastes gourmet. Our tuna melt is made with toasted bread, filled with a creamy tuna mixture, and topped with melted cheese. This melt is a protein-packed sandwich that cooks in just 15 minutes.

Let me paint you a picture: it’s lunchtime, you have only 10 minutes, and pantry staples… what do you do? You make a tuna sandwich, of course! While we do love a classic cold tuna sandwich, this tuna melt takes that to the next level. Just like our gourmet grilled cheese, this sandwich is loaded with fresh tomatoes and melted cheese. This sandwich is simple, but it isn’t boring!
Ingredients for Crispy Tuna Melt Sandwich
- Canned tuna – Your favorite canned tuna, drained.
- Onion – Diced onion adds a great crunch and flavor to the creamy tuna filling. You do want to make sure you finely chop the onion.
- Garlic – Freshly minced garlic adds a great boost of flavor.
- Mayo – Mayonnaise makes the filling creamy and flavorful.
- Tomato – A ripe, sliced tomato adds the perfect juiciness to this sandwich. Though optional, it adds so much flavor.
- Sliced cheese – We use cheddar cheese for this sandwich, but you can also use mozzarella or even pepper jack cheese.
- Bread – Sliced sandwich bread from scratch is the best way to elevate this sandwich.

Pro Tip of The Day:
- No soggy sandwich. When crisping a sandwich in a pan, it’s essential to use a warm pan to achieve a crispy exterior.

How to Store Leftover Tuna Melt
- When it comes to leftovers, store leftover tuna spread on its own, rather than the assembled sandwich. Add the creamy tuna mixture to an airtight container and refrigerate for 1-2 days.
