french onion soup crostini


French onion soup is one of my favorite things to eat. The caramelized onions are sweet and have a deep, rich flavor. It’s one of the best recipes to make during the colder months. I had the idea to turn classic French onion soup into French onion soup crostini bites. These are a low cost and delicious recipe to make during the Holidays. It’s a great Holiday recipe that you will make time and time again. I guarantee your guests will devour these at your next Holiday party. These French onion soup crostini are extremally economical to make because the main ingredients are onions, baguette and cheese. I used raclette cheese for these crostini, but you can switch it up and use any cheese that melts beautifully, like Gruyere, Comte or Fontina cheese. You can even make the caramelized onions a few days in advance. This will make hosting during the Holidays a lot easier. I always like to choose recipes that can be made ahead if I’m hosting a dinner party. The assembly is easy, all you need to do is toast the baguette, rub with garlic and then layer on the caramelized onions, top with shredded cheese and bake until golden.

french onion soup crostini
Prep time: 15 minutes
Cook time: 50 minutes
Total time: 1 hour 5 minutes
Servings: 6-8
Ingredients
- 5 cups white onions, sliced thin (about 7-8 small onions)
- 1/4 cup dry red wine
- 4-5 dashes Worcehstershire
- 1 tbsp unsalted butter
- 1 tsp thyme (fresh or dried)
- olive oil
- 1 baguette
- 1 clove garlic
- Chives to garnish
- 1 cup shredded Raclette cheese (or any other melting cheese like Gruyere, or Comte)
Directions
- Cut the onions in half then slice thinly. Heat a large pan to medium-low heat. Add the olive oil and butter. Once hot, add the onions. Stir them and turn the heat to low. Cover with a lid and cook for 20 minutes until translucent.
- Remove the lid and turn up the heat to medium. Stirring periodically. Once they start to brown, add salt, pepper, thyme, Worcestershire and red wine. Sautee for 15 minutes (turn the heat down if needed). Cook until the wine has reduced and the onions have developed a golden brown colour. This should take 25-30 minutes. If the onions are cooking too quickly, lower the heat and add a splash of water.
- Slice the baguette and arrange on a baking sheet. Brush with olive oil on both sides. Bake in the oven at 375° for 15 minutes, flipping halfway through. Remove from the oven and rub garlic on each slice (while the bread is still hot).
- Add a spoonful of caramelized onions and a sprinkle of cheese. Set the oven to broil and bake for a few minutes until the cheese is melted and slightly golden. Garnish with chives.
