Why You’ll Love This Healthy Tuna Melt

- No mayo required: Cottage cheese provides creaminess with more protein and less fat than mayonnaise, while blending seamlessly with the tuna and herbs.
- Bright, herby flavor: Fresh dill and parsley add lightness and freshness that elevate a classic tuna melt.
- Fast to make: About five minutes of prep and one minute under the broiler or a few minutes in an air fryer gets this on the table quickly.
Featured Ingredients
- Canned tuna: Solid white albacore packed in water is a good option; drain it thoroughly to avoid soggy bread.
- Cottage cheese: 2% cottage cheese stands in for mayo, adding creaminess and extra protein without heavy fat.
- Fresh herbs: Dill and parsley bring brightness — use fresh herbs rather than dried for best flavor.
- Green onions: Provide a mild onion crunch and gentle bite that complements the herbs.
- Sourdough: Thick-cut sourdough holds the topping well and toasts nicely for texture and flavor.
- Muenster cheese: Melts beautifully and offers a mild, buttery finish that pairs well with the herby tuna salad.
How to Make a Healthy Tuna Melt
This recipe is straightforward: mix drained tuna with cottage cheese and fresh herbs, spread the mixture on toasted sourdough, top with muenster, and broil or air-fry until the cheese is melted and slightly golden. The entire process is efficient and results in a warm, crisp sandwich with creamy, flavorful tuna salad.
Tips for the Best Tuna Melt
- Drain the tuna well: Remove excess water by pressing the tuna against the can or using a strainer. This prevents soggy bread.
- Toast the bread first: Toasting creates a sturdy base and improves texture under the tuna salad.
- Watch the broiler: Broiling takes only a minute or so; keep the oven door slightly open and watch closely to avoid burning.
- Use thick-cut bread: A substantial slice of sourdough gives structure and a satisfying crunch.
Variations
- Cheese alternatives: Swap muenster for cheddar, Swiss, provolone, or pepper jack depending on your taste.
- Bread options: Whole wheat, rye, English muffins, or gluten-free slices all work — just be sure to toast them.
- Extra mix-ins: Add diced celery, capers, red pepper flakes, or everything bagel seasoning for more crunch and flavor.
- Air fryer method: Assemble the tuna melt and air fry at 400°F for 3–4 minutes until the cheese is melted and bubbly.
- Wrap version: Use a tortilla instead of bread to make a warm tuna wrap with the same cottage cheese base.
Storage
- Make-ahead filling: The cottage cheese tuna salad can be prepared in advance and stored in an airtight container in the refrigerator for up to three days.
- Assemble when ready: For best texture, assemble and broil or air fry right before serving rather than pre-assembling.
- Not recommended for freezing: Freezing alters the texture of cottage cheese and bread, so avoid freezing the finished sandwich.
