Ingredient List

For the Crostini

• 1 baguette, sliced into ½-inch thick pieces
• 2 tablespoons olive oil

For the Topping

• 6 ounces cremini or button mushrooms, sliced
• 4 slices bacon, chopped
• 2 cloves garlic, minced
• 1 tablespoon butter
• Salt and pepper, to taste
• 2 tablespoons fresh parsley, chopped (optional)
• ¼ cup grated Parmesan cheese (optional)

Ingredient Notes

• I always use a fresh baguette because it toasts up perfectly crispy without getting too hard.
• Don’t skip the garlic—it really brightens up the mushrooms and bacon.
• For bacon, I prefer thick-cut; it crisps nicely and adds great texture.
• Cremini mushrooms give a nice depth of flavor, but button mushrooms work well too if that’s what you have on hand.
• Adding Parmesan is optional but highly recommended—it adds a lovely salty finish.
• Fresh parsley is great for a pop of color and freshness, but you can leave it out if you’re in a pinch.

Kitchen Equipment Needed

• Baking sheet: For toasting the baguette slices evenly.
• Skillet or frying pan: To cook the bacon and sauté the mushrooms.
• Knife: For chopping bacon, slicing mushrooms, and mincing garlic.
• Cutting board: A sturdy surface for all your chopping prep.
• Mixing spoon or spatula: To stir the mushrooms and bacon as they cook.
• Small bowl: Optional, for mixing garlic with butter before adding to mushrooms.
• Oven or toaster oven: To crisp up the crostini slices—my favorite is a toaster oven for quick batches.

Instructions

Step 1: Prepare and Toast the Baguette Slices

• Preheat your oven to 375°F (190°C).
• Arrange the baguette slices in a single layer on a baking sheet.
• Brush each slice lightly with olive oil on both sides.
• Place the baking sheet in the oven and toast for about 8-10 minutes, flipping halfway through, until the bread is golden and crispy.
  Pro tip: Keep an eye on the bread during the last few minutes so it doesn’t burn—every oven is a little different!

Step 2: Cook the Bacon

• While the bread is toasting, heat a skillet over medium heat.
• Add the chopped bacon and cook, stirring occasionally, until it’s crispy and browned, about 6-8 minutes.
• Use a slotted spoon to remove the bacon and place it on a paper towel-lined plate to drain excess fat.

Step 3: Sauté the Mushrooms and Garlic

• Carefully drain most of the bacon fat from the skillet, leaving about 1 tablespoon to cook the mushrooms.
• Add the butter and minced garlic to the skillet and sauté for about 30 seconds until fragrant.
• Add the sliced mushrooms and cook, stirring frequently, until they release their moisture and become tender and slightly browned—about 6-7 minutes.
• Season with salt and pepper to taste.

Step 4: Combine Bacon and Mushrooms

• Return the cooked bacon to the skillet and mix it with the mushrooms until everything is evenly combined and heated through.
• Remove from heat and stir in the chopped parsley if using.

Step 5: Assemble the Crostini

• Spoon a generous amount of the bacon mushroom mixture onto each toasted baguette slice.
• Sprinkle with grated Parmesan cheese if desired.
• Serve immediately while the crostini are still warm and crispy.

Pro tip: Serve these crostini fresh for the best crunch—if they sit too long, the bread can get soggy.

Tips and Tricks for Success

• Use day-old baguette or bread if possible—it toasts up better and holds toppings without getting soggy.
• Don’t overcrowd the mushrooms in the pan; cook them in a single layer for better browning.
• Let the bacon drain well on paper towels to keep it crispy and avoid greasy crostini.
• If you want extra flavor, deglaze the mushroom pan with a splash of white wine or balsamic vinegar before mixing in the bacon.
• Serve crostini immediately after assembling to maintain that perfect crunch.

Ingredient Substitutions and Variations

• Swap bacon for pancetta or prosciutto for a slightly different smoky flavor.
• Use shiitake or portobello mushrooms instead of cremini for a richer, meatier texture.
• Replace Parmesan with goat cheese or cream cheese for a creamier topping.
• Add caramelized onions or sautéed spinach for an extra veggie boost.
• Drizzle with honey or balsamic glaze for a sweet and tangy twist.

Serving Suggestions

• Serve these crostini as an appetizer alongside a light mixed greens salad with a lemon vinaigrette—I love how the freshness cuts through the richness.
• Pair with a glass of dry white wine or a crisp rosé for a simple but elegant snack.
• Make a brunch spread by adding these crostini to a board with fresh fruit, cheeses, and nuts.
• I often serve them with a bowl of creamy tomato soup for a cozy and satisfying lunch.
• Add a side of roasted vegetables or a charcuterie board for a complete party platter.

Storage and Reheating Instructions

• Store leftover bacon mushroom mixture in an airtight container in the fridge for up to 3 days.
• Keep toasted baguette slices separate in a paper bag to maintain crispness.
• To reheat the topping, gently warm it in a skillet over low heat until heated through.
• Refresh the crostini by toasting the bread slices again for 2-3 minutes before assembling.
• Avoid assembling crostini ahead of time to prevent soggy bread. Assemble just before serving for best results.
