Ingredients

• 1 (15-ounce) can cannellini beans, rinsed and drained: Cannellini beans, also known as white kidney beans, are the star of the show. Their creamy texture and mild, slightly nutty flavor make them ideal for mashing and creating a smooth, flavorful base. Rinsing removes excess sodium and canning liquid, ensuring the purest bean flavor.
• 2 cloves garlic, minced: Fresh garlic is essential for that pungent, aromatic kick that balances the creaminess of the beans. Mincing ensures even distribution of flavor throughout the mixture.
• 2 tablespoons fresh lemon juice: Lemon juice brightens the entire dish, adding a vital acidity that cuts through the richness of the beans and olive oil. Freshly squeezed juice is always preferred for its vibrant flavor.
• 1/4 cup extra virgin olive oil, plus more for drizzling: Good quality extra virgin olive oil is crucial for both flavor and texture. It contributes to the creamy consistency of the bean mixture and adds a fruity, peppery note. Extra oil for drizzling at the end enhances the visual appeal and adds a final layer of richness.
• 2 tablespoons chopped fresh rosemary: Rosemary provides a robust, piney, and slightly peppery flavor that complements the beans and garlic beautifully. Fresh rosemary is preferred for its aromatic intensity.
• Salt and freshly ground black pepper to taste: Seasoning is key to bringing out all the flavors. Salt enhances the overall taste, while freshly ground black pepper adds a subtle spice and depth.
• 1 baguette, sliced into 1/2-inch thick rounds: A baguette is the classic choice for crostini. Its shape and texture are perfect for toasting and holding toppings. Slicing into 1/2-inch rounds ensures even toasting and a good balance of crispness and chewiness.
• Optional toppings: Flaky sea salt, red pepper flakes, grated Parmesan cheese, fresh parsley, sun-dried tomatoes, balsamic glaze (for added flavor and visual appeal).

Instructions

1. Prepare the White Bean Mixture: Begin by ensuring your cannellini beans are thoroughly rinsed and drained. This step is important to remove excess starch and sodium from the canning liquid, which can affect the flavor and texture of your bean mixture. Place the rinsed and drained cannellini beans into a medium-sized bowl.
2. Add Flavor Enhancers: To the bowl of beans, add the minced garlic and fresh lemon juice. The garlic will infuse its pungent aroma and savory depth into the beans, while the lemon juice will provide a bright, acidic counterpoint to the richness of the beans, preventing the mixture from becoming too heavy.
3. Mash and Emulsify: Using a fork or a potato masher, begin to mash the cannellini beans. As you mash, gradually drizzle in the extra virgin olive oil. The olive oil is not just for flavor; it also helps to create a smooth and creamy texture, emulsifying with the mashed beans to form a cohesive and luxurious spread. Continue mashing and adding olive oil until you reach your desired consistency – you want it to be creamy and spreadable but still have a bit of texture. Don’t over-mash to a complete puree, as a little bit of bean texture is pleasant.
4. Incorporate Rosemary and Season: Stir in the chopped fresh rosemary. Rosemary’s piney and slightly peppery notes will beautifully complement the creamy beans and garlic. Season the mixture generously with salt and freshly ground black pepper. Taste and adjust the seasoning as needed. Remember, seasoning is crucial for bringing out the best flavors in simple dishes like this. You can add a pinch more salt or pepper, or a little more lemon juice, depending on your preference.
5. Prepare the Crostini: Preheat your oven to 375°F (190°C). While the oven is preheating, slice the baguette into ½-inch thick rounds. Arrange the baguette slices in a single layer on a baking sheet.
6. Toast the Bread: Place the baking sheet in the preheated oven and toast the baguette slices for about 8-10 minutes, or until they are lightly golden and crisp. Keep a close eye on them to prevent burning, as oven temperatures can vary. You want them to be crisp enough to hold the bean mixture without becoming soggy but not so hard that they are difficult to bite into.
7. Assemble the Crostini: Once the crostini are toasted and slightly cooled, spoon a generous amount of the creamy white bean mixture onto each slice. Spread it evenly to ensure each bite is flavorful.
8. Finishing Touches and Serve: Drizzle a little extra virgin olive oil over the top of the assembled crostini. This adds a final touch of richness and visual appeal. If desired, sprinkle with flaky sea salt, a pinch of red pepper flakes for a hint of heat, or a grating of Parmesan cheese for a salty, umami element. Fresh parsley adds a pop of color and freshness, while sun-dried tomatoes offer a chewy, sweet, and tangy contrast. Balsamic glaze can add a touch of sweetness and acidity. Serve immediately and enjoy the delightful combination of creamy, flavorful white beans and crispy, golden crostini!

Additional Tips for Perfect Creamy Mashed White Bean Crostini

To ensure your Creamy Mashed White Bean Crostini are always a hit, here are seven helpful tips:

1. Use Quality Ingredients: The simplicity of this recipe means the quality of ingredients truly shines through. Opt for good quality extra virgin olive oil and fresh, fragrant rosemary. The flavor difference is noticeable.
2. Don’t Skip the Lemon Juice: The lemon juice is crucial for brightening the flavor and preventing the bean mixture from tasting heavy or bland. Freshly squeezed lemon juice is always best for its vibrant, zesty flavor.
3. Toast the Crostini Just Right: Toast the baguette slices until they are golden brown and crisp, but not burnt. Over-toasted crostini can be too hard to bite into, while under-toasted crostini can become soggy. Keep a close watch on them in the oven.
4. Adjust the Consistency: If you prefer a smoother bean mixture, you can use an immersion blender or food processor to blend it to your desired consistency. For a chunkier texture, stick with mashing by hand. You can also add a tablespoon or two of water or more olive oil if the mixture seems too thick.
5. Make it Ahead (Partially): You can prepare the white bean mixture up to 2 days in advance and store it in an airtight container in the refrigerator. Toast the crostini and assemble just before serving to maintain optimal crispness and freshness. This is a great time-saver for entertaining.
6. Experiment with Flavors: Feel free to customize the bean mixture with other herbs and spices. Thyme, oregano, or sage would be delicious alternatives to rosemary. A pinch of red pepper flakes added to the bean mixture can provide a subtle heat. You can also add roasted garlic for a sweeter, mellower garlic flavor.
7. Consider Different Toppings: While the basic recipe is delicious, don’t be afraid to get creative with toppings. Roasted vegetables like bell peppers or zucchini, marinated artichoke hearts, pesto, or a sprinkle of crumbled feta cheese can all add exciting layers of flavor and texture.

Frequently Asked Questions (FAQ)

Q1: Can I make this recipe vegan?
A: Yes, absolutely! This recipe is naturally vegetarian. To make it vegan, simply ensure you don’t use any cheese toppings. It’s delicious as is in its vegan form.

Q2: Can I use a different type of white bean?
A: Yes, while cannellini beans are recommended for their creamy texture, you can substitute them with other white beans like Great Northern beans or navy beans. The texture might be slightly different, but the flavor will still be delicious.

Q3: How long can I store leftover white bean mixture?
A: You can store leftover white bean mixture in an airtight container in the refrigerator for up to 3 days. The flavor might even deepen overnight. Just give it a good stir before using.

Q4: Can I make the crostini gluten-free?
A: Yes, to make gluten-free crostini, simply use gluten-free baguette slices or gluten-free crackers instead of traditional baguette. There are many excellent gluten-free bread options available.

Q5: Can I use dried rosemary instead of fresh?
A: While fresh rosemary is preferred for its vibrant flavor and aroma, you can use dried rosemary in a pinch. Use about 1 teaspoon of dried rosemary for every 2 tablespoons of fresh rosemary. Remember that dried herbs are more concentrated in flavor, so use less.

Q6: What if I don’t have a baguette? Can I use other bread?
A: Yes, you can use other types of bread for crostini. Sourdough bread, ciabatta, or even regular sliced bread (cut into smaller pieces) can be toasted and used. Adjust the toasting time accordingly based on the thickness and type of bread you use. Baguette is classic for its shape and texture, but versatility is key!
