Chef's note: The flavor from cooked dried beans is delicious, but you can also use canned white beans here if you want to make this recipe and you don't have time to cook the beans from scratch. Substitute 1 (15-ounce) can of white cannelloni beans, drained, with a bit of the bean liquid reserved.
For superior flavor, take the time to cook the cannellini beans from scratch; their rich, earthy notes will elevate the bruschetta significantly. If using canned beans, ensure to reserve some liquid for adjusting the topping's consistency. When grilling the baguette, monitor closely as high heat can quickly burn the bread; aim for a golden crisp. The quality of your extra-virgin olive oil significantly impacts the final taste, so choose a good one. Don't skip swiping the toasted bread with fresh garlic—it adds a subtle, aromatic punch. Taste and adjust seasoning with lemon juice, salt, and pepper just before serving to ensure a balanced, vibrant flavor.
