Ingredients for Onion Blue Cheese Crostini
Baguette: A classic French bread that is sliced and toasted to create the base for the crostini.
Olive oil: Used for brushing the baguette slices before toasting, adding a rich flavor and helping to achieve a crispy texture.
Onion: Caramelized to bring out its natural sweetness, providing a delicious contrast to the tangy blue cheese.
Vegan blue cheese: A plant-based alternative to traditional blue cheese, offering a similar tangy and creamy flavor.
Salt: Enhances the flavor of the caramelized onions.
Pepper: Adds a touch of heat and depth to the caramelized onions.
Technique Tip for This Recipe
When caramelizing onions, ensure you cook them slowly over medium-low heat. This allows the natural sugars in the onions to break down and develop a rich, sweet flavor. Stir occasionally to prevent burning and achieve an even, golden-brown color.

Alternative Ingredients
baguette - Substitute with gluten-free baguette: For those who are gluten intolerant or prefer a gluten-free option, a gluten-free baguette will provide a similar texture and taste.
olive oil - Substitute with avocado oil: Avocado oil has a high smoke point and a neutral flavor, making it a good alternative for brushing on the bread.
onion - Substitute with shallots: Shallots have a milder and slightly sweeter flavor compared to onions, which can add a more delicate taste to the crostini.
vegan blue cheese - Substitute with vegan feta cheese: Vegan feta cheese has a tangy and salty flavor that can mimic the sharpness of blue cheese, providing a similar taste profile.
salt - Substitute with sea salt: Sea salt can offer a more complex flavor compared to regular table salt, enhancing the overall taste of the dish.
pepper - Substitute with white pepper: White pepper has a milder flavor and can add a subtle heat without overpowering the other ingredients.

How To Store / Freeze This Recipe
- Allow the crostini to cool completely before storing to prevent sogginess.
- Place the caramelized onions in an airtight container and refrigerate. They can last up to 3-4 days.
- Store the toasted baguette slices in a resealable plastic bag or airtight container at room temperature for up to 2 days.
- Keep the vegan blue cheese in its original packaging or transfer it to an airtight container. Refrigerate and use within a week.
- For freezing, wrap each baguette slice individually in plastic wrap to maintain crispness, then place them in a freezer-safe bag. They can be frozen for up to 3 months.
- Freeze the caramelized onions in small portions using ice cube trays or small containers. Once frozen, transfer them to a freezer-safe bag for up to 3 months.
- When ready to serve, reheat the baguette slices in a preheated oven at 350°F (175°C) for about 5-7 minutes until crisp.
- Thaw the caramelized onions in the refrigerator overnight or reheat them directly in a pan over low heat until warmed through.
- Assemble the crostini just before serving to ensure the best texture and flavor.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Arrange the leftover crostini on a baking sheet. Bake for about 5-7 minutes or until the baguette slices are crispy and the vegan blue cheese is slightly melted.
For a quicker method, use a toaster oven. Set it to 350°F (175°C) and place the crostini inside. Toast for about 3-5 minutes, keeping an eye on them to ensure they don't burn.
If you prefer using a stovetop, heat a non-stick skillet over medium heat. Place the crostini in the skillet, cover with a lid, and heat for about 2-3 minutes. This will help the vegan blue cheese to warm up and the baguette to regain some crispiness.
For a microwave option, place the crostini on a microwave-safe plate. Heat on medium power for about 20-30 seconds. Be cautious as this method may make the baguette a bit chewy rather than crispy.
If you have an air fryer, preheat it to 350°F (175°C). Place the crostini in the basket and air fry for about 3-4 minutes. This method will help maintain the crispiness of the baguette while warming the vegan blue cheese and caramelized onions.
