Croissant Club Sandwich with Crispy Prosciutto
jump toRECIPE
The club sandwich is a classic you’ll find on nearly every diner menu across America – but this croissant club sandwich takes it to the next level. Unlike traditional club sandwiches that can sometimes be dry, this version stays juicy and flavorful thanks to creamy avocado slices. Crispy prosciutto adds a salty crunch that’s lighter than bacon, with less fat and a more delicate flavor, making this sandwich both indulgent and balanced. Layered with fresh ingredients on buttery, flaky croissants, it’s a decadent twist on a familiar favorite that’s perfect for brunch, lunch, or an easy weeknight meal. If this recipe hits the spot, you’ll definitely enjoy this bacon turkey garden sandwich and Brie and prosciutto sandwich.
Why You’ll Love This Recipe
- Buttery and flaky: Croissants take this classic club sandwich to the next level with their rich, tender layers.
- Salty crunch: Crispy prosciutto adds a satisfying texture and a lighter, less fatty alternative to bacon.
- Quick and easy: Assembles in minutes using simple, fresh ingredients—perfect for brunch, lunch, or a casual dinner.
Key Ingredients in This Recipe
- Croissant – When it comes to buying the croissants, face it, not all croissants were created equal. This sandwich is best when you find that big, buttery, flakey croissant and then pile everything into it.
- Prosciutto – Everyone’s favorite charcuterie! Prosciutto is a whole muscle salumi served sliced paper-thin. I crisp it up by broiling it to use in place of bacon in this sandwich.
- Tomato – I use juicy, flavorful tomatoes on the vine or beefsteak tomatoes in this recipe.
- Turkey – Deli-sliced roasted turkey is layered with fresh ingredients on this buttery croissant sandwich. I get it freshly cut at the deli-counter rather than buying pre-sliced and pre-packaged turkey, which often has additives.
- Havarti cheese – I use Havarti, this semi-soft Danish cow’s milk cheese in this club sandwich. It’s similar to provolone.
A full ingredient list with exact amounts can be found in the recipe card below.
Tips and Tricks for the Best Croissant Club Sandwich
- Warm the croissants: Toasting or lightly warming the croissants enhances their flakiness and adds flavor.
- Prevent sogginess: Spread a thin layer of mayo or mustard on the croissant to create a barrier between the bread and juicy ingredients.
- Even layers: Slice ingredients evenly to make each bite balanced and easier to eat.
Swaps and Substitutions
- Protein: Swap prosciutto for crispy bacon, and other favorite deli meats like smoked ham, or roasted chicken for turkey. For a vegetarian option, try sliced hard-boiled eggs or grilled halloumi.
- Cheese: I love mild Havarti but you can also use your favorite deli-sliced cheeses like Swiss, provolone or even a creamy Brie.
- Bread: While croissants make this sandwich special, you can use brioche buns, sourdough, or ciabatta in a pinch. Toast lightly to mimic the croissant’s crisp texture.
- Avocado: Substitute mashed avocado with a light spread of pesto, aioli, or hummus for extra flavor.
- Greens: Butter lettuce or arugula add freshness, but spinach or mixed greens are great alternatives if that’s what you have on hand.
- Add-ons: Try caramelized onions, or even a fried egg for an extra brunch-inspired twist.
How to Make a Croissant Club Sandwich (Step-by-step)
Preheat oven broiler to high. Lay slices of prosciutto out on a baking sheet in a single layer. Broil until the prosciutto is crisp, about 3 minutes. Be sure to check on the prosciutto frequently so it does not burn.
Slice the croissants in half lengthwise then spread mayo on the bottom half. Layer with lettuce, followed by the turkey, slices of crispy prosciutto, havarti, tomato, onion, cucumber and avocado.
FAQ – Frequently Asked Questions
Yes! You can prep the ingredients ahead of time, but it’s best to assemble the sandwich right before serving to keep the croissant flaky and the avocado fresh. If prepping ahead of time I recommend wrapping it in butcher paper.
Yes! Crispy bacon works, but prosciutto gives a lighter, less fatty flavor that pairs beautifully with avocado.
Yes! Omit the meat and add extra layers of cheese, additional avocado, roasted vegetables, or a fried egg.
