2bleu’s Mushroom and Swiss Crostini: An Appetizer That Scores Big

I remember the first time I made these little bites. It was game night, and my friend Mark, a notoriously picky eater, was coming over. He’s a meat-and-potatoes kind of guy, generally suspicious of anything with the word “mushroom” in it. I wanted to impress him, but also sneak some slightly more sophisticated flavors into the mix. The aroma of the sautéed mushrooms mingling with the nutty Swiss and toasted bread filled the kitchen, and even he couldn’t resist sneaking a taste. He devoured them – every single one! That’s when I knew this Mushroom and Swiss Crostini was a guaranteed touchdown every time.

Recipe Overview

• Prep Time: 12 minutes
• Cook Time: 3-5 minutes
• Total Time: 12 minutes
• Servings: 12
• Yield: 12 crostini
• Dietary Type: Vegetarian

Ingredients

• 1 loaf crusty Italian bread, sliced thin and toasted (you can use a crusty French bread or a 6 oz bag of New Yorker Bagel Chips works nice also)
• 3 cloves garlic, minced
• 3 shallots, peeled and chopped fine
• 2 tablespoons olive oil
• 2 tablespoons red bell peppers, diced small
• 4 cups fresh mushrooms, sliced small and thin (assorted)
• 1 tablespoon herbs (suggested Buddha’s Herb Mix for Mushrooms or your favorite blend)
• 8 ounces Swiss cheese, shredded (use the best quality)

Equipment Needed

• Cookie sheet(s)
• Parchment paper
• Large skillet
• Spatula
• Knife
• Cutting board

Instructions

1. Preheat your broiler on the low setting. Place parchment paper onto a cookie sheet (or two, depending on the size of your oven and cookie sheets).

2. Lay out the toasted bread evenly onto the cookie sheet(s). Set aside.

3. In a large skillet, heat the olive oil over medium-high heat. Add the minced garlic and finely chopped shallots, and cook for 2 minutes, stirring constantly to prevent burning. The garlic and shallots should become fragrant and softened.

4. Add the diced red bell peppers to the skillet and sauté for another 1-2 minutes, stirring frequently, until they begin to soften slightly.

5. Add the sliced mushrooms to the skillet. Cook, stirring occasionally, for about 3-5 minutes, or until the mushrooms are tender and have released their moisture. Be careful not to overcrowd the pan, as this will steam the mushrooms instead of browning them. If necessary, cook the mushrooms in batches.

6. Stir in the assorted herbs into the mushroom mixture, ensuring they are evenly distributed.

7. Place a small amount of the mushroom mixture on top of each bread slice (about 1 teaspoon each).

8. Sprinkle the shredded Swiss cheese evenly over the mushrooms.

9. Broil on the low setting for 1-2 minutes, or until the cheese is melted, bubbly, and lightly browned. Watch carefully to prevent burning.

10. Serve immediately and enjoy!

Expert Tips & Tricks

• Mushroom Magic: Don’t be afraid to experiment with different types of mushrooms. Cremini, shiitake, oyster, and even a touch of truffle oil can elevate the flavor profile. Just be sure to slice them thinly and cook them until they are tender and slightly browned.
• Toast Time: If you are using a baguette for your crostini, slice it about 1/2 inch thick and brush lightly with olive oil before toasting. This will help prevent them from becoming too dry and hard. A light toasting is all they need, as they will be broiled later.
• Sharpness Matters: Using a high-quality Swiss cheese with a sharp, nutty flavor will make a big difference. Look for a cheese that is aged for at least 6 months for the best flavor. Gruyere is a great substitute if you are in the mood for something similar but with a slightly bolder taste.
• Make-Ahead Marvel: You can prepare the mushroom mixture ahead of time and store it in the refrigerator for up to 2 days. Just be sure to reheat it before topping the crostini.
• Broiler Beware: Keep a close eye on the crostini while they are under the broiler, as they can burn quickly. The goal is to melt the cheese and give it a slightly golden-brown color.

Serving & Storage Suggestions

Serve these Mushroom and Swiss Crostini immediately while the cheese is melted and bubbly. Arrange them artfully on a platter, perhaps garnished with a sprinkle of fresh herbs or a drizzle of balsamic glaze for visual appeal.

Leftovers, if any, can be stored in an airtight container in the refrigerator for up to 2 days. Reheat them in the oven or under the broiler until the cheese is melted and warmed through. Be aware that the crostini may lose some of their crispness during storage. Reheating in a toaster oven can help restore some of the original texture. These are best enjoyed fresh, though!

FAQs (Frequently Asked Questions)

Q: Can I use dried mushrooms instead of fresh?

A: While fresh mushrooms are ideal for their texture and flavor, you can use dried mushrooms in a pinch. Rehydrate them in hot water before adding them to the skillet. Be sure to squeeze out any excess water before cooking.

Q: What if I don’t have shallots?

A: If you don’t have shallots on hand, you can substitute them with finely chopped yellow onion. The flavor will be slightly different, but still delicious.

Q: Can I make this ahead of time and freeze it?

A: It’s not recommended to freeze the assembled crostini, as the bread may become soggy upon thawing. However, you can freeze the mushroom mixture for up to 1 month. Thaw it in the refrigerator overnight before using.

Q: My broiler is very strong. How do I prevent the crostini from burning?

A: Keep a close eye on the crostini while they are under the broiler. If your broiler is very strong, you may need to lower the rack or reduce the broiling time.

Q: What kind of herbs should I use?

A: A combination of dried thyme, rosemary, and parsley works well. Fresh herbs, such as chives or parsley, can also be sprinkled on top after broiling for added flavor and freshness.
