What is a Turkey Dijon Melt Sandwich?

A Turkey Dijon Melt Sandwich is basically comfort food dressed in casual Friday clothes. Think: toasted sandwich bread, turkey (leftover or deli-style), honey Dijon mustard, melted cheese, red onion, and just enough butter to make it all crispy on the outside. It’s the kind of sandwich that feels like it took effort, but actually came together in under 15 minutes.

The honey Dijon brings a sweet and tangy kick that elevates the turkey without overpowering it. And let’s not sleep on Monterrey Jack—it’s mellow, creamy, and melts like a dream. Whether you’re whipping this up after work or trying to impress a picky eater without breaking a sweat, the Turkey Dijon Melt Sandwich hits that sweet spot of easy and satisfying.

Reasons to Try Turkey Dijon Melt Sandwiches

Let’s be real—dinner needs to be fast, tasty, and something your kids won’t dissect like a science project. Turkey Dijon Melt Sandwiches check all those boxes. First, they’re quick. From fridge to table in under 15 minutes? Yes, please. Second, they’re flexible—you can swap in sourdough, wheat, or even that white bread hiding in the freezer. Deli turkey or leftover roast both work great.

And third, it’s that buttery, golden crust and gooey cheese combo that turns this into something way more exciting than just another turkey sandwich. If you loved Cheesy Baked Chicken Tenders or crave a mouthwatering steak bite, you’ll appreciate this melty handheld comfort. Plus, you can dress it up or down depending on your pantry situation. Lazy dinner night just got an upgrade.

Ingredients Needed to Make Turkey Dijon Melt Sandwiches

• 8 slices of sandwich bread (white, wheat, or sourdough)
• 4 tablespoons mayonnaise
• 8 ounces sliced turkey (deli or leftover roasted)
• 6 ounces Monterrey Jack cheese, sliced
• ½ medium red onion, thinly sliced
• Salt and black pepper to taste
• 3 tablespoons honey Dijon mustard
• 4 tablespoons softened butter

Instructions to Make Turkey Dijon Melt Sandwiches

Ready to make the ultimate Turkey Dijon Melt Sandwiches? This step by step guide walks you through the whole process with helpful tips so you can get that crispy outside and melty inside every single time. Let’s do it.

Step 1: Lay the Foundation

Start by laying out all 8 slices of sandwich bread on a clean cutting board or counter. You can go with white, wheat, or sourdough—whatever your pantry or preferences call for. Sourdough adds a nice tang, while wheat gives it a little nuttiness. Just make sure it’s sturdy enough to hold up on the skillet without going soggy.
On 4 of the slices, spread about a tablespoon of mayonnaise evenly over one side. This will be the base layer of the sandwich and adds that rich, creamy bite. If you’re looking for a lighter alternative, you could try swapping in Greek yogurt or avocado spread (more on that in our Healthy Chicken Pot Pie Soup recipe notes).

Step 2: Build the Layers

Now take the mayo-spread slices and start layering on the turkey. You’ll want around 2 ounces per sandwich, spread out evenly so every bite gets some love. If you’re using leftover roasted turkey, slice it thinly for even coverage. Deli-style thick-cut turkey is fantastic for texture and that classic deli bite.
Next up: red onion. Thinly slice about half a medium red onion and place a few rings over the turkey. It adds a nice crunch and sharpness that cuts through the richness. If raw onions aren’t your thing, give them a quick soak in cold water for 10 minutes to take the edge off.

Sprinkle on a bit of salt and freshly ground black pepper to season the filling. Don’t skip this step—it really helps bring out all the flavors, even in a simple sandwich. Now, add the cheese. Monterrey Jack is ideal here because it melts like a dream and has a mild, buttery taste. Use 1.5 ounces per sandwich and make sure it covers the turkey completely. Pro tip: if you’re out of Monterrey Jack, Swiss or provolone work great too—check our Cheesy Chicken and Rice Casserole for other melt-worthy cheese ideas.

Top each built half with one of the remaining slices of bread, mustard side facing down. That honey Dijon brings just the right blend of sweet and tangy to balance everything out.

Step 3: Butter Up

Now it’s time to get those sandwiches ready for the skillet. Take your softened butter and spread it generously on the outside of each sandwich (the side that will hit the pan first). Use about ½ tablespoon per slice. This is key to getting that golden, crispy crust.
If your butter’s too cold, a quick trick is to microwave it for 5–7 seconds to soften just enough without melting. Spread it edge to edge—it acts like a flavor glue, creating that satisfying sizzle once it hits the heat.

Step 4: Toast to Perfection

Preheat a large skillet or nonstick griddle over medium heat. You want it hot enough to toast the bread slowly and evenly, without burning. Once it’s ready, place your sandwiches in, buttered side down. Don’t overcrowd the pan; give them space to breathe.

Cook each side for 3 to 4 minutes, pressing down gently with a spatula as they cook. You’re aiming for golden-brown and crisp on the outside, with cheese oozing on the inside. This step by step part is where patience pays off—keep the heat steady, and flip carefully using a flat spatula. If your pan is small, work in batches.

Step 5: Rest and Slice

Once both sides are golden and the cheese is melted through, carefully remove the sandwiches from the pan. Let them rest on a cutting board for about a minute. This short rest lets the cheese set just enough to prevent a full-on lava flow when you slice.
Use a sharp knife to cut the sandwiches diagonally—because diagonal just feels right, doesn’t it? Serve hot with chips, soup, or one of our favorite comfort sides like Ultimate Baked Mac and Cheese or a simple salad for balance.

What to Serve with Turkey Dijon Melt Sandwiches

These sandwiches are hearty on their own but even better with a few sides. Try a bowl of slow cooker vegetable soup or creamy potato salad to round it out. Want something warm and cozy? Easy Crock Pot Chicken Pot Pie would be a great companion on chilly nights. For crunch, go for kettle chips or a pickle spear. And if it’s lunch hour and you’re pressed for time, a handful of baby carrots or a simple green salad is enough to make it feel like a real meal without the extra effort.

Key Tips for Making Turkey Dijon Melt Sandwiches

Use thick-cut turkey if you can—thin slices tend to get lost in the mix. Don’t skimp on the cheese; Monterrey Jack melts evenly and complements the tangy Dijon. Preheat your skillet before adding the sandwiches to get that perfect crispy sear. If your bread’s too soft, it might soak up the butter and not crisp well—opt for sturdier sandwich bread. And finally, resist the urge to press the sandwich too hard while cooking—you want it melty, not smashed. Looking to experiment? Add spinach or swap the cheese for provolone. Want more melty ideas?

Storage and Reheating Tips for Turkey Dijon Melt Sandwiches

Got leftovers? You’re not alone. Wrap extra sandwiches in foil and pop them in the fridge for up to 2 days. To reheat, skip the microwave—unless you’re into soggy bread. Instead, warm them up in a skillet over medium-low heat for 3–4 minutes per side. You can also use a toaster oven at 350°F for about 10 minutes. If prepping ahead, you can build the sandwiches (minus buttering the outsides) and store them wrapped until ready to cook. These don’t freeze well since mayo and onions tend to mess with texture after thawing. But let’s be honest—they probably won’t last that long anyway.

FAQs

Can I use a different cheese?
Absolutely. Swiss, provolone, or even sharp cheddar all melt nicely. Monterrey Jack is just a mild, melty go-to.

What if I don’t have honey Dijon?
Mix a bit of regular mustard with honey—it’s not fancy, but it works and still gives you that sweet-tangy balance.

Can I make these ahead of time?
You can assemble them and refrigerate for a few hours. Just don’t grill until you’re ready to eat.

Can I make this gluten-free?
Yep—just sub in your favorite gluten-free sandwich bread. Everything else stays the same.

How do I keep them crispy?
Use medium heat, don’t overcrowd the pan, and always butter the outside. Crispy magic, guaranteed.
