Best Red Onion Crostini Recipes

CARAMELIZED RED ONION SOUP WITH GOAT CHEESE CROSTINI

Steps:

• Heat a heavy saucepan over medium heat. Spray the pan with non-stick cooking spray and add onions, garlic, sugar, and thyme; season with salt and pepper.
• Cook, stirring often, until onions are quite soft but haven't begun to color, about 25 minutes.
• Pour in the wine and deglaze the pan, stirring with a spoon to loosen browned bits from the bottom of the pan. Simmer over medium heat until the liquid has evaporated, about 15 minutes.
• Add the broth and simmer over medium heat until reduced to about 4 cups, about 10 minutes.
• Meanwhile, spread goat cheese on the toasted bread slices.
• Ladle soup into 4 warmed bowls and float 2 toasts in each bowl. Garnish with thyme sprigs if desired.
• Serve hot.

TOMATO, RED ONION AND ROCKET SALAD WITH FRIED EGG, GRILLED CHORIZO AND GRILLED PROVOLETO CROSTINI

Steps:

• Two hours before grilling, remove the provolone cheese from the refrigerator and let sit at room temperature. Letting the cheese sit out in the air will allow the cheese to form a crust and make it easier to grill.
• Preheat the grill to medium-high direct heat, leaving some space for indirect cooking.
• Grill the chorizo, turning occasionally, until nicely charred and hot inside, about15 minutes. Chop roughly and set aside.
• Heat a griddle over the direct heat. Lightly brush the top of the cheese with canola oil and season with salt and pepper. Place on the griddle, seasoned-side down, and cook until the cheese is dark golden brown and crusty, about 5 minutes. Brush the top lightly with oil, season again, carefully flip over and move the griddle to the indirect heat. Continue cooking until the bottom begins to turn light brown and the cheese is melty, covering if need be. Remove to a plate and sprinkle with the oregano and red pepper flakes.
• Brush the bread on each side with some olive oil and sprinkle with salt and pepper. Grill over direct heat for about 1 minute per side-the bread should be crisp and a bit charred outside, but chewy inside.
• Heat a griddle or cast-iron skillet over medium-high heat. Add the butter and melt. Crack the eggs into the skillet, sprinkle with salt and pepper and cover with another pan. Cook until the whites are set and the yolks still runny, about 3 minutes.
• While the eggs cook, whisk together the vinegar and mustard in a large bowl and season with salt and pepper. Slowly whisk in 1/2 cup olive oil until emulsified. Taste and whisk in the honey if desired. Put the rocket, tomatoes and onions in a large bowl and season with salt and pepper. Drizzle some vinaigrette around the sides of the bowl and gently toss to coat.
• To serve: Smear some cheese on the toasted bread. Top with an egg, chopped chorizo, a drizzle of olive oil and parsley leaves. Serve each crostini with some rocket salad.

WHITE BEAN RAGOUT CROSTINI WITH RED ONION JAM

Steps:

• Note: Beans do not need to be soaked. Rinse beans and place in an All-Clad 3.5 quart round oven. Cover with 8 cups water and add carrot, celery, shallot, garlic and 2 teaspoons salt. Bring to a simmer, cover, and continue to cook over very low heat until beans are soft, about 1 hour 20 minutes. Remove vegetables and bay leaf. Drain liquid from beans and return to pot. Mash with a potato masher until smooth, but still somewhat textured. Season with remaining 2 teaspoons salt, olive oil and lemon juice and mix well.
• In a large skillet, heat olive oil over medium heat. Add onions and salt and saute until soft and somewhat translucent, about 15 minutes. Add wine, brown sugar and balsamic vinegar and reduce heat to low. Continue to cook until liquid is almost completely gone, about 30 minutes longer. Stir in red wine vinegar and check seasoning, adding more vinegar if desired.
• Preheat oven to 350 degrees. Brush both sides of the bread slices with olive oil and arrange in a single layer on rimmed baking sheets. Bake until golden and crispy, about 15 minutes. As soon as the bread is cool enough to handle, rub one side with garlic clove to infuse with flavor. Top each crostini with about 1 tablespoon bean ragout and 1 1/2 teaspoons of onion jam. Top with mint chiffonade and drizzle with olive oil.

CROSTINI WITH RICOTTA AND RED-ONION JAM

Steps:

• In a small saucepan, combine butter, red onion, and sugar; season with salt and pepper. Cover and cook over medium-low, stirring every 10 minutes, until onion is soft and slightly caramelized, 30 minutes. Add wine and vinegar and cook, uncovered, stirring occasionally, until mixture is thick and glossy, about 20 minutes. Let onion jam cool to room temperature (or cover and refrigerate, up to 3 days; bring to room temperature before using). Divide ricotta among crostini and top with onion jam.

RED ONION CROSTINI

Steps:

• Heat 3 tablespoons oil in large skillet over medium-high heat. Add pancetta; sauté 3 minutes. Add onions, garlic, lemon juice and fennel seeds; sauté until onions begin to brown, about 10 minutes. Reduce heat to medium; cover and cook until onions are tender, stirring occasionally, about 20 minutes. Remove from heat. Stir in vinegar. Season with salt and pepper. (Can be made 1 day ahead. Cover; chill. Rewarm over medium-low heat before continuing.)
• Drizzle each toast slice with 1 teaspoon oil. Divide onion mixture among toasts. Sprinkle with parsley and serve.
