PARTNER POST – Get inspired with creatively crafted Castello Blue Cheese as we celebrate a Summer of Blue with #BluesdayTuesday.
A traditional French Connection is slathered with garlic butter and layered with crisp cucumber slices, brie blue cheese, and onion for a simply delightful sandwich.
By Kimberly Killebrew

Cheese has a way of reconnecting me to my original home of Europe. Every time I sample some European cheese my mind is taken back to the lands and regions where I spent my childhood.
And that’s what food is largely about for me. It either connects or reconnects me with places I know and love or places I’ve never been but long to experience.

One of my favorite European excursions was heading to King’s Lynn and stopping at their “bap” shop (that’s what the Brit’s call bread rolls) for a particular sandwich: The French Connection. I have no idea if this tiny sandwich shop is still in existence, but they offered a nice selection of filled baps. But the one my mom and I always got was this French-inspired delight that was slathered down with a generous amount of fresh garlic butter, mayonnaise, and then layered with crispy cucumber, onions, and a generous amount of brie.
Castello’s world-class European-imported cheese has reconnected me to my home on many occasions, including this one. I was able to try some of their fabulous blue-veined brie and of course it immediately made me think of those wonderful sandwiches in King’s Lynn. I thought if there was one way to improve upon the French Connection it would be to use a brie that has some glorious blue cheese veins running through it.

So today I’m sharing the recipe for the French Connection and I’m doubling up this time – I’m going to show you how to make it TWO ways: The traditional way and in hors d’oeuvres form, which is absolutely fabulous. I promise your guests will love them!
PrintCastello Summer of Blue — The French Connection Sandwich with Cucumber and Blue Cheese
- Total Time: 15 minutes
- Yield: 4 sandwiches or 24 hors d'oeuvres 1x
Description
A traditional French Connection sandwich, enhanced with garlic butter, crisp cucumber slices, brie blue cheese, and onion, offering a taste of European delight.
Ingredients
- 4 large soft rolls (if making hors d’oeuvres instead, cut 24 round circles out of sandwich bread about 2 inches in diameter and proceed using the standard directions)
- Large wedge of brie, at room temperature
- 1 cucumber, washed and thinly sliced
- 1 small onion, thinly sliced
- Mayonnaise
For the Garlic Butter:
- ¼ cup unsalted butter, at room temperature
- 2 large cloves garlic, smashed and finely minced
- 2 tablespoons chopped fresh parsley
- 1/8 teaspoon salt
Instructions
- In a small bowl, combine the softened butter and minced garlic to make the garlic butter. Set aside.
- If the garlic butter has been stored in the fridge, allow it to soften at room temperature before using.
- Spread the bottom half of each roll with a generous amount of garlic butter.
- Spread a layer of mayonnaise over the garlic butter.
- Layer the cucumber slices evenly over the mayonnaise.
- Add a layer of thinly sliced onions on top of the cucumbers.
- Generously layer slices of brie blue cheese over the onions.
- Place the top half of the roll on the sandwich and press down gently.
- If making hors d’oeuvres, follow the same layering process on each bread circle.
Notes
For a more intense garlic flavor, prepare the garlic butter a day in advance and store it in the fridge. Serve the sandwiches immediately for the best texture. If making hors d’oeuvres, they are perfect for parties and can be prepared a few hours in advance and stored in the fridge until serving.
