If you ask Tom Selleck what comfort food sends him right back to his childhood, don’t expect him to talk about filet mignon or trendy avocado toast.
Instead, the Magnum, P.I. star has confessed that his favorite throwback meal isn’t fancy at all; it’s a crunchy, cheesy tuna melt sandwich straight out of his mom’s kitchen.
Simple yet satisfying, this open‑faced classic has been part of Selleck’s life since he was a kid, a nostalgic staple that still satisfies decades later.
This isn’t some reinvented gourmet concoction; it’s old‑fashioned comfort food at its best. What makes this sandwich timeless isn’t complexity; it’s texture, flavor, and the memories you chew with each bite.
How this sandwich became a classic
The story of this sandwich begins not in a restaurant kitchen, but right at home. According to Selleck’s mother, Martha Selleck, her son grew up eating this crunchy tuna melt when he came in from school hungry and ready for something hearty.
The recipe was later published in Murder, She Cooked: A Cabot Cove Cookbook, preserving Martha Selleck’s version for home cooks.
Broiling the sandwich open‑faced was a clever way to make a warm, comforting meal without fuss. The cheese gets beautifully melted and slightly caramelized, while the veggies keep the tuna mixture fresh and crunchy, a contrast in texture that makes every bite satisfying and memorable.
Ingredients you’ll need for this tuna melt
Here’s everything you’ll want to have on hand before assembling Selleck’s favorite sandwich. These ingredients combine to create that perfect blend of creamy tuna, crunch from fresh vegetables, and melty, golden cheese:
Ingredients list:
- 2 cans (about 6 to 6½ ounces each) water-packed tuna, drained and flaked.
- 2 tablespoons mayonnaise.
- 1–2 teaspoons fresh lemon juice.
- A dash of black pepper.
- 2–3 tablespoons finely chopped celery.
- 2–3 tablespoons finely chopped green bell pepper.
- 2–3 tablespoons finely chopped onion.
- 2 slices of your favorite bread, toasted.
- 2 slices Monterey Jack or cheddar cheese.
Each component plays a role: the celery and peppers add texture and brightness, the lemon cuts through the richness, and the toasted bread gives the sandwich character. Don’t skip the broiling step; it’s what transforms this from a basic lunch into something truly crave-worthy.

How to assemble the sandwich
Start by preparing the tuna mixture in a medium bowl. Combine the drained tuna with mayonnaise, fresh lemon juice, black pepper, finely chopped celery, green bell pepper, and onion.
Mix gently but thoroughly so every bite is balanced, and the colors and textures of the vegetables shine through. This combination is what gives the sandwich its signature crunch and freshness.
Next, prepare your bread by toasting the slices until they are golden and crisp. The toasted bread adds a satisfying crunch and prevents the tuna mixture from making the sandwich soggy.
Spread the tuna salad generously over the toasted bread, making sure each slice is fully covered. The tuna should be piled thick enough to create a hearty, satisfying bite.
Top each sandwich with slices of cheese. The original recipe uses either cheddar or Monterey Jack, both of which melt well under the broiler. Once the sandwiches are assembled, place them under the broiler for just a few minutes.
Watch carefully so the cheese bubbles and turns golden, but does not burn. This quick broil melds the flavors together and gives the sandwich its irresistible finish.
Once the cheese is perfectly melted, remove the sandwiches from the broiler and let them cool for a minute so the filling sets slightly. Serve warm for maximum comfort, and enjoy a taste of classic, old-school nostalgia just like Tom Selleck has for decades.
Elevate your tuna melt like a pro
To make this classic sandwich truly shine, a few simple tips go a long way. First, always drain your tuna well to prevent a soggy sandwich, but leave just a little oil or juice for extra flavor. Mixing the vegetables finely ensures each bite has a balanced crunch without overwhelming the tuna.
Toasting the bread until golden brown is crucial as it provides a sturdy base and a satisfying texture contrast with the creamy tuna.

When broiling, keep a close eye on the cheese. Just a minute or two under high heat is enough to bubble and lightly brown it; overdoing it can turn the sandwich bitter or dry.
For added flavor, consider a small squeeze of fresh lemon over the tuna mixture or a sprinkle of paprika on top before broiling. With these tips, every bite will capture the same nostalgic magic that Tom Selleck has cherished for decades.
Serving tips and tasty twists
Once your sandwich is ready, consider pairing it with crisp pickles or a simple green salad to balance the richness. While the original is delightful as it is, modern cooks often add small twists.
A pinch of hot sauce can spice up the tuna mixture, or Kewpie mayonnaise can add extra creaminess. Some even layer thin pickle slices on top before broiling for a tangy crunch that complements the melted cheese.
Even with these variations, the classic open-faced version remains the star. It’s simple, comforting, and exactly the kind of sandwich that makes home-cooked meals unforgettable.
