Turkey, Brie, and Plum Baguette Sandwich with Honey Thyme Mustard

Freshly baked baguette, roast turkey, sliced brie, and sweet slices of ripe plum make for the perfect picnic sandwich. Smother the bread with a smear of honey thyme mustard for that extra pop that balances out the creamy and sweet notes. My Turkey, Brie, and Plum Sandwich is truly a picnic winner.

One of the joys of traveling in France is learning to appreciate how simple food can feel deeply special. A fresh baguette, good cheese, ripe fruit, and a spot in the park are often all that’s needed for an afternoon meal. The beauty of a French picnic is in the quality of the ingredients—the crusty baguette with its chewy center, the soft brie that melts slightly in the warmth of the day, the effortless feeling of slowing down long enough to enjoy it all.

When planning my Romantic Picnic Menu, I knew I wanted to borrow from that spirit with a simple baguette sandwich. Thinly layered turkey and creamy brie create the foundation, but the real appeal is in the balance and restraint of the ingredients. This isn’t meant to be an overstuffed sandwich piled impossibly high. Instead, every layer has a purpose.

There are a few details that make this Turkey, Brie, and Plum Baguette Sandwich especially memorable. The first is the addition of ripe fruit tucked between the layers. Here, I used thin slices of plum to tie into the plum rose pastries served for dessert, though peach or crisp apple would work beautifully as well. The fruit adds a subtle sweetness that makes the sandwich feel fresh and a little unexpected.

The second is the honey-thyme mustard spread generously onto both sides of the baguette. Sweet, sharp, and lightly herbal, it ties the whole sandwich together and gives it just enough complexity without overpowering the simplicity of the ingredients.

And finally, the arugula. Rather than simply layering it onto the sandwich plain, I like to toss it lightly with olive oil, a splash of balsamic vinegar, and a pinch of kosher salt first. It’s a small detail, but it transforms the greens from an afterthought into something peppery, balanced, and essential to the sandwich as a whole.

Perfectly packable and easy to transport, this sandwich is made for outdoor dinners, concerts in the park, and slow evenings under the stars. Paired with a crispy chickpea couscous salad and delicate plum rose pastries, it becomes part of a picnic menu that feels both elegant and unfussy at the same time.

Bring along a blanket, something sparkling to drink, and enjoy the kind of meal that reminds you how lovely simple food can be.

Tips for a Perfect Picnic Lunch

• The Honey Thyme Mustard for this sandwich can be made in advance. Then, when it comes time to make the picnic, its more about assembling this sandwich.
• I like to keep the turkey and cheese layer very thin here to keep it elegant.
• You can toast the baguette if you’d like. I personally prefer not toasting it as I think it makes it a bit easier to eat.
• Dressing the arugula really is the secret here to making the sandwich feel composed and adding an extra level of flavor.
• You could switch out the plums for other stone fruit like peaches or you could try apples as well.
• Try this as a panini if you’re serving the picnic at home! It would be delicious warm.

An Elevated Outdoor Lunch

This turkey, brie, and plum baguette sandwich was designed as part of my simply romantic picnic lunch menu. It’s balanced with a crispy chickpea salad on the side that has lusciously creamy feta dressing and sweet plum roses for dessert. It’s a truly effortlessly elegant meal to pack and share.

These sandwiches would pair nicely with some of the other salads on The Mid Century Modern Romantic, so you can build your own lunch menu if you’d like. I think the Chicken Caprese Farro Salad would match very well here for a heartier lunch option. For a simpler option, try my Simple Arugula Salad which couldn’t be easier. Or pair it with my delicious Citrus and Vanilla Macerated Fruit for a ladies lunch.

Enjoy these turkey and brie sandwiches! I know the honey thyme mustard is going to be turning up on lots of sandwiches moving forward!
