I fell in love with the French Connection sandwich the first time I tasted the cool crunch of cucumber against creamy brie and a smear of garlicky butter. It’s a small, elegant combination that feels fancy but comes together in minutes. I like it as a lunch, a light dinner, or as hors d’oeuvres when friends drop by.

This recipe shows you two formats: full sandwiches built on soft rolls, and bite-sized rounds for a party. The method is the same; only the bread changes. I’ll walk you through the simple garlic butter, the assembly, and practical swaps so you can make it with what you have.

No fuss, no special equipment. If you have a wedge of brie, a cucumber, a small onion and mayonnaise on hand, you can put these together in under 20 minutes. Read the shopping list, follow the clear steps, and you’ll have crisp, balanced sandwiches that taste thoughtful without much effort.

Shopping List

Keep this list handy when you shop or check your pantry. It covers the main components for both the full sandwiches and the hors d’oeuvres version.

4 large soft rolls (or sandwich bread if making rounds)
Large wedge of brie
1 cucumber
1 small onion
Mayonnaise
Unsalted butter
Fresh garlic
Fresh parsley
Salt

Ingredients

4 large soft rolls — split in half horizontally for sandwiches; if making hors d’oeuvres, cut 24 round circles from sandwich bread about 2 inches in diameter and use pairs as bottoms and tops.
Large wedge of brie — bring to room temperature so it slices easily; thin slices cover each roll half or bread round.
1 cucumber — washed and thinly sliced; provides crunch and freshness.
1 small onion — thinly sliced for a mild bite; adjust amount to taste.
Mayonnaise — spread on top halves for creaminess and bind.
1/4 cup unsalted butter — at room temperature for the garlic butter; gives richness without being greasy.
2 large cloves garlic — smashed and finely minced into the butter for bright, savory flavor.
2 tablespoons chopped fresh parsley — folded into the garlic butter for color and a fresh herbal note.
1/8 teaspoon salt — to season the garlic butter; balances flavors.

Make French Connection Sandwich (Two Ways): A Simple Method

Make the garlic butter: in a small bowl, combine 1/4 cup unsalted butter (at room temperature), 2 smashed and finely minced garlic cloves, 2 tablespoons chopped fresh parsley, and 1/8 teaspoon salt. Stir until smooth and evenly mixed. If you refrigerate it, let it soften at room temperature before using.
Prepare the bread:
- For full sandwiches: split the 4 large soft rolls in half horizontally.
- For hors d’oeuvres: cut 24 round circles about 2 inches in diameter from sandwich bread. You will use pairs of rounds (one bottom, one top) to make each hors d’oeuvre.
Prepare the cheese and produce: ensure the wedge of brie is at room temperature, then slice it thinly so each roll half or bread round can be covered. Wash and thinly slice the cucumber. Thinly slice the small onion.
Assemble each sandwich or hors d’oeuvre base: spread a generous amount of the garlic butter on each bottom roll half or bottom bread round.
Prepare the tops: spread mayonnaise on each top roll half or top bread round.
Layer the fillings on each buttered bottom: place cucumber slices, a slice of brie, then a few thin onion slices on top of the cucumber. For hors d’oeuvres, use one cucumber slice and a proportionally sized piece of brie and onion so the toppings fit the rounds.
Close and finish: place the mayonnaise-spread top half onto each assembled bottom. For hors d’oeuvres, you may secure each sandwich round with a toothpick down the center if desired.
Serve immediately. Makes 4 sandwiches or 12 hors d’oeuvres.

Why This Recipe Is Reliable

This sandwich relies on contrast: rich brie, crunchy cucumber, sharp onion, and a buttery garlic base. The flavors are simple and forgiving. If one component is slightly different — a tangier mayo, a firmer roll — the overall balance still holds because each element plays a single, clear role.

The garlic butter is the glue. It doesn’t need to be complex to add depth. Mixing butter with garlic and parsley gives a compound butter that spreads smoothly and flavors every bite without overpowering the brie. Using room-temperature brie ensures even, delicate slices that meld with the cucumber texture.

Finally, the method is quick and repeatable. No toasting needed, no cooking time. That makes it ideal when you want something fresh and assembled in a hurry, or when you need consistent hors d’oeuvres for guests.

If You’re Out Of…

I’ll give quick, practical swaps that keep the sandwich honest.

No brie? Use any mild, creamy cheese that slices thinly (Camembert or a soft mild goat cheese in a thin slab can work). Keep the slicing thin so it mirrors the texture pattern.
No fresh parsley? Omit it or use a small pinch of dried parsley; the garlic is the main flavor driver, so you won’t lose much.
No fresh garlic? Use 1/2 teaspoon garlic powder mixed into the butter as a last resort — but fresh minced garlic is preferable for brightness.
No soft rolls? Use sandwich bread for full-size sandwiches (two slices per sandwich) or baguette slices for a firmer bite. If you switch bread, adjust the brie and cucumber thickness so the balance remains.

Cook’s Kit

Minimal kit required. Here’s what I use every time because it speeds things up without being excessive.

Small mixing bowl and spoon — to make the garlic butter.
Sharp knife — for thin, even slices of brie, cucumber and onion.
Cutting board — separate sections for cheese and produce makes assembly cleaner.
Biscuit cutter or small round cutter (about 2 inches) — optional for hors d’oeuvres; a clean drinking glass works if you don’t have a cutter.
Toothpicks — for securing the hors d’oeuvres, optional but helpful for guests.

Troubleshooting Tips

Short, actionable fixes for common issues.

Garlic butter too stiff: Let it sit at room temperature 10–15 minutes or microwave in 5-second bursts until spreadable. Don’t overheat.
Brie won’t slice thinly: Make sure it’s at room temperature. Chill briefly only if it’s too soft, but gentle warmth slices best.
Bread tears when cutting rounds: Use a serrated or very sharp knife, and press straight down without sawing. Chill bread slightly if it’s too soft.
Sandwich soggy after sitting: Assemble just before serving. For hors d’oeuvres, place garlic-buttered bottoms and mayo-topped tops separately and close them right before guests arrive.

Make It Your Way

Small tweaks you can try to make this your signature version.

Add a thin smear of grainy mustard under the brie for a touch of tang and texture.
Swap parsley for chopped chives for a milder, onion-like lift in the garlic butter.
For extra crunch, layer a few watercress leaves or thin arugula under the cucumber.
If you prefer a sharper onion note, soak thin onion slices in cold water for 10 minutes, drain well, then use. It removes some bite but keeps the flavor.

Insider Tips

Little habits that make a faster, cleaner assembly and tastier results.

Slice the brie with a warm knife: run the knife under hot water, dry it, then slice. It gives cleaner cuts and fewer tears.
Layering order matters: garlic butter on the bottom, mayo on top. The butter flavors the bread and meets the brie; mayo on top keeps the top from sliding and adds richness without making the bottom soggy.
When cutting rounds for hors d’oeuvres, aim for uniformity so toppings fit neatly and presentation is tidy.

Prep Ahead & Store

Prep smartly to save time without sacrificing texture.

Make the garlic butter up to 2 days ahead. Store it wrapped in plastic or in a covered container in the refrigerator. Bring to room temperature before spreading.
Slice the cucumber and onion up to a few hours ahead. Keep them in separate sealed containers and pat dry before assembly to avoid excess moisture.
Do not assemble sandwiches more than 30–60 minutes before serving; the bread will begin to soften as the brie and cucumber release moisture.
Leftovers: assembled full sandwiches are best eaten the same day. If you must store, wrap tightly and refrigerate up to 24 hours, then expect softer bread and slightly less crisp cucumber.

Frequently Asked Questions

Answers to questions I get most often when I share this at home or on the blog.

Can I toast the bread? Yes. Toasting changes the texture and adds warmth, which melts the brie slightly for a different mouthfeel. If you toast, apply garlic butter after to preserve the butter’s raw garlic flavor.
How do I keep the cucumber from making the bread soggy? Slice cucumber thin and pat dry on paper towels. Spread the garlic butter generously on the bottom bread to create a flavor buffer and slight barrier.
Is there a vegetarian protein you’d recommend adding? If you want more substance, add thin slices of roasted red pepper or a smear of hummus under the cucumber. Those stay fresh without overpowering the brie.
Can I scale this recipe? Yes. The method scales linearly: double the ingredients for more sandwiches or hors d’oeuvres. Prepare extra garlic butter; it stores well.

Hungry for More?

If you liked this, try pairing the sandwiches with a simple mixed greens salad tossed in lemon vinaigrette, or serve the hors d’oeuvres alongside a bowl of marinated olives. For dessert, fruit tarts or a light sorbet keep the meal feeling bright and balanced.
