What You Need For This Deliciousness!

The Ciabatta Roll: A Crusty Foundation

Every great sandwich starts with a solid foundation, and in this case, it’s a crusty ciabatta roll. The ciabatta roll’s crispy exterior and light, airy interior provide the perfect contrast to the tender roast beef and creamy Swiss cheese. Its chewiness adds an extra dimension to every bite, ensuring that each mouthful is a delight for your taste buds. Any good crusty roll will do also! Here’s a recipe to make your own ciabatta rolls, Ciabatta Rolls Recipe | King Arthur Baking.

The Roast Beef: Tender and Flavorful

The star of this sandwich is undoubtedly the succulent roast beef. Use roast beef that’s been cooked to perfection, and either shredded or sliced thin. Another great beef is beef tenderloin on this sandwich! Grilled medium rare, a taste of heaven! The tender, juicy meat should practically melt in your mouth, providing a satisfying contrast to the crusty ciabatta roll. The richness and depth of flavor in the roast beef serve as the base for the layers.

Swiss Cheese: Creamy and Nutty

Swiss cheese is the perfect choice because its slightly nutty and buttery flavor pairs exceptionally well with roast beef. It should be sliced thinly or shredded to ensure it melts easily and envelops the roast beef in a blanket of cheesy goodness. When warmed, the cheese becomes delightfully gooey.

Caramelized Onions: Sweet and Savory

Caramelized onions take this sandwich to the next level with their sweet and savory notes. Slowly cooked until golden brown, the onions develop a rich, complex flavor that adds depth and sweetness to each bite.

Garlic Aioli: Creamy and Tangy

No sandwich is complete without a flavorful spread, and in this case garlic aiolli is it! The garlic aioli is a creamy, tangy sauce made by combining garlic, mayonnaise, lemon juice, and a touch of seasoning. Its pungent, garlicky flavor cuts through the richness of the other ingredients, adding a zesty kick to every bite. The smooth, velvety texture of the aioli perfectly complements the roast beef, Swiss cheese, and caramelized onions, tying all the flavors together.

How To Make Ciabatta Onion Beef Bombs

Begin by making your garlic aioli sauce and place in fridge to chill. Caramelize the onions. Split the ciabatta rolls in 1/2 and butter each cut side or drizzle with a bit of olive oil and grill on a hot griddle or skillet. Spread a good tablespoon of garlic aiolli on each 1/2 of the grilled ciabatta. Place about 1/2 cup of thinly sliced or shredded beef on bottom 1/2 of roll. Place swiss on top of beef and place in a 375F-degree oven and bake until beef is hot and cheese melts. Remove from oven and top with caramelized onions. Sprinkle with fresh chopped chives for added flavor! Now …. enjoy!!!

Notes

Roasting garlic is a simple and delicious way to bring out its natural sweetness and mellow flavor. 
  1. Preheat your oven to 400°F (200°C).
  2. Take a whole head of garlic and remove any loose outer layers of skin, leaving the head intact.
  3. Using a sharp knife, cut about 1/4 inch (0.6 cm) off the top of the garlic head, exposing the cloves.
  4. Place the garlic head on a sheet of aluminum foil or in a small oven-safe dish.
  5. Drizzle about 1 tablespoon of olive oil over the top of the garlic head, making sure to coat the exposed cloves.
  6. Optionally, you can sprinkle a pinch of salt and pepper over the garlic for added flavor.
  7. Wrap the garlic tightly in the aluminum foil or cover the dish with aluminum foil to create a sealed packet.
  8. Place the garlic in the preheated oven and roast for approximately 40-45 minutes, or until the cloves are soft and golden brown.
  9. Remove the garlic from the oven and allow it to cool for a few minutes until it’s safe to handle.
  10. Once the garlic has cooled slightly, carefully squeeze the bottom of the head, pushing the roasted cloves out of their skins. They should come out easily and have a soft, creamy texture.
  11. Use the roasted garlic immediately in your favorite recipes or store it in an airtight container in the refrigerator for up to a week.
Roasted garlic can be used in a variety of dishes, such as mashed potatoes, pasta sauces, soups, spreads, and dressings. Its sweet and rich flavor adds depth to any recipe. Enjoy!
