Next, arrange the English muffin halves or bread slices on the baking sheet.

Step 3:

Top each half with tuna salad, dividing it evenly among the slices.

Recipe tips and variations

1. Fewer Carbs: Instead of bread, wrap your tuna salad in a romaine lettuce wrap or use slices of keto bread.
2. Spicy: add 1 finely diced jalapeño to your tuna salad.
3. Cheese: I love sharp cheddar cheese, but you can use any type you want! Try Swiss, Colby, Jalapeño Jack, or Monetary.
4. Bread: I love tuna melts on sourdough slices or English muffins. You can also use white bread, whole wheat, whole grain, or a bagel.
5. Tortilla Wrap: Feel free to use a tortilla wrap too!
6. Remove the Tomato: If you don't like tomatoes, no problem! Just remove them from the recipe.
7. Don't store tuna melts: Tuna melts are best enjoyed warm straight out of the oven. If you plan to meal prep this recipe, store the tuna salad separately and assemble the sandwich when you are ready to enjoy. If not, the bread will be soggy.

Frequently Asked Questions

What's the best bread for tuna melts?

You can use any bread for tuna melts. I recommend typing sourdough bread, English muffins, white bread, whole wheat, or seeded grain bread. Try to stay away from softer types of bread like challah, brioche, Hawaiian, or focaccia.

Can I use an English muffin?

Yes, I love open-face tuna melts on English muffins. Feel free to use white, whole wheat, or gluten-free English muffins.

Can I use a bagel?

Yes, you can also use a bagel for these open-face tuna melts. Since bagels are thicker than slices of bread, I like to toast them for 3 - 4 minutes before adding the tuna salad, tomato slices, and cheese on top.

Can I use gluten-free bread?

Absolutely! Use your favorite gluten-free bread or English muffin. I love Canyon Road Bakhouse.

How long does tuna salad last?

Tuna salad lasts up to 5 days if stored in airtight containers in the refrigerator.

Can I make this tuna melt dairy-free?

Yes! Simply use dairy-free cheese and swap the Greek yogurt in the tuna salad with dairy-free yogurt or mayo.

Are open-face tuna melts healthy?

I consider open-face tuna melts to be healthy. They have less calories, fewer carbs, and will leave you full for hours. In this recipe, we use homemade tuna salad without mayo, a healthy alternative to classic tuna salads.

Storage tips:

Tuna melts are best enjoyed warm straight out of the oven. I don't recommend storing a full sandwich. If you want to store extras for meal prep, simply keep your tuna salad in an airtight container in the refrigerator. When you are ready to enjoy a tuna melt, assemble it, bake, and enjoy!
