Pepper Mushroom Onion Crostini is the perfect way to enjoy a summer appetizer or light lunch.
Why you should make Pepper Mushroom Crostini
Bell Peppers are in season in July. As with most produce you will find the most flavorful and sweet bell pepper in the heat of summer. Roasting them with onions and mushrooms allows them to really shine. Topping this mix on a crusty toasted bread is the perfect way to enjoy an appetizer with friends or a light lunch. Great with a crisp white wine on a warm summer night with the laughter of friends sounds magical to me.
How to make the Baguette into perfectly toasted Crostini
Make sure that you slice your bread evenly. You want them to be almost the same thickness, so that they cook evenly. You also want the bread to be thick enough to hold the toppings, but not too thick to eat. About ½” thickness is perfect.
Layer your bread evenly. You do not want the bread to overlap. Then drizzle your olive oil over bread to help with toasting.
Keep an eye on your bread once you place it under the broiler. It will toast up quickly, and burn even quicker.
How to make Pepper Mushroom Crostini
The key to enjoying this recipe at its best is to use the freshest produce and good quality bread. Pick a Red Bell Pepper that is firm and has not started to wrinkle. This will allow it to hold up well in the cooking process. Use a sweet yellow onion so that the flavor doesn’t overpower the Red Bell Pepper and Mushrooms. Any mushroom will work in this recipe, but I like the small baby shiitake as they are easier to place on the bread.
You can use an artisan baguette or sourdough in this recipe, but I feel the artisan offers a crisper foundation for the topping.
As always, use good quality extra virgin olive oil and parmesan cheese.
How to season your vegetables to perfection
You want to add salt and pepper after you add each vegetable. This allows the vegetables to be evenly seasoned. As long as you keep your heat at a medium, and stir occasionally you really can allow your vegetables to soften and season to perfection.
Your vegetables can be made ahead of time and stored at room temperature for several hours. If you need to store longer, store in the refrigerator and remove at least 30 minutes before serving to let the olive oil come to room temperature.
