Learning how to make crostini at home is simple and rewarding. Thin slices of a crusty baguette are brushed with a flavorful mixture of melted butter, extra-virgin olive oil and fresh garlic, then baked until golden and crisp. These little toasts make an elegant base for a wide range of toppings and pair beautifully with dips, soups, salads and pasta dishes.
This easy crostini recipe is ideal for party appetizers or everyday meals. The crostini can be prepared in advance and stored until you’re ready to serve, which saves time on busy entertaining days while keeping your presentation effortless.
Kellie’s Note
Start the Party
Crostini are one of my favorite party starters because they’re versatile and always look inviting. A warm, buttery crostini complements both bright, acidic toppings like tomato bruschetta and richer combinations like goat cheese with fruit. They transform simple ingredients into elegant bites and are perfect for creating a beautiful appetizer board.
These toasts are lighter than a grilled cheese alongside soup but still provide great texture and flavor. Serve plain crouton-style with soups like tomato or French onion, or dress them up with savory or sweet toppings to impress guests without spending hours in the kitchen.

Ingredients for Crostini
- Baguette: A crusty, day-old baguette slices cleanly and dries out to a crisp texture. Sourdough baguette or a narrow ciabatta also work well.
- Butter: Adds richness and helps the bread brown. Use salted or unsalted according to preference.
- Olive oil: Helps the crostini crisp without becoming heavy. Extra-virgin olive oil gives the best flavor.
- Garlic: Fresh garlic delivers bright savory notes; finely grate or mince so the flavor is evenly distributed.
- Salt: A light sprinkle enhances flavor, especially if using unsalted butter.
Ingredient Substitutions
To make dairy-free crostini, omit the butter and increase the olive oil. If you prefer a more evenly distributed garlic flavor, substitute a small pinch of garlic powder for fresh garlic.
How to Make Crostini
A few simple steps yield crisp, golden crostini perfect for appetizers or as a crunchy accompaniment to soups and salads.
- Preheat the oven: Heat the oven to 375°F (190°C).
- Slice the bread: Use a sharp serrated knife to cut the baguette into even ¼-inch slices. Slice straight across for small bites or on the diagonal for larger, more elegant pieces.
- Make the butter mixture: In a small bowl stir together melted butter, extra-virgin olive oil, minced or grated garlic and a pinch of salt.
- Brush the bread: Arrange the slices in a single layer on a baking sheet and lightly brush both sides with the butter and oil mixture.
- Bake: Bake for 5 minutes, flip the slices, then bake another 3–4 minutes until centers are dry and edges are lightly golden.
- Cool: Transfer to a wire rack to cool completely before storing or topping.
Crostini also make a sturdy, flavorful substitute for crackers when serving hot or cold dips.
Tips for Perfectly Crispy Crostini
- Use a sharp serrated knife to avoid compressing the bread while slicing.
- Slice evenly: Consistent thickness ensures all slices finish at the same time.
- Brush lightly: Too much butter or oil can prevent the bread from crisping.
- Single layer baking: Arrange slices with a little space between them so air circulates.
- Flip once: Turn crostini halfway through to toast both sides evenly.
- Watch closely: Thin slices can brown fast during the last minutes.
- Test for doneness: Crostini are ready when centers feel dry and crisp and edges are golden.
- For extra crunch: Add 1–2 minutes per side for a darker, crunchier finish.
- Cool completely before storing: This prevents condensation from softening the toasts.
- Add toppings just before serving so the crostini remain crisp.
What Is the Best Bread for Crostini?
A crusty, day-old baguette is ideal. Its narrow shape creates appetizer-sized slices and the firm crumb crisps perfectly to support dips, cheeses and other toppings. Sourdough baguettes, ciabatta or other firm artisan loaves are good alternatives. Avoid soft sandwich bread, which can become soggy under moist toppings. If using fresh bread, add an extra minute or two in the oven to thoroughly dry it out.
How to Slice Crostini
- Keep slices about ¼-inch thick so they crisp without falling apart.
- Slice straight across for small, bite-sized rounds.
- Slice on the diagonal for larger pieces with more room for toppings.
Crostini Variations
- Classic Olive Oil: Brush with extra-virgin olive oil and finish with flaky salt.
- Garlic Parmesan: Sprinkle grated Parmesan before baking for a nutty finish.
- Italian Herb: Add dried oregano, basil or Italian seasoning to the butter mixture.
- Spicy: Mix in crushed red pepper flakes or a pinch of Cajun seasoning.
- Fresh Garlic Rub: Bake with olive oil, then rub warm crostini with a cut garlic clove for mellow garlic flavor.
- Black Pepper Finish: Crack fresh black pepper over the slices before baking.
Crostini Topping Ideas
Crostini can be dressed with almost any topping. Try these combinations:
- Tomato bruschetta with fresh basil and a drizzle of balsamic glaze
- Goat cheese, fig jam and prosciutto
- Ricotta, honey, fresh berries and mint
- Herbed Boursin, roasted tomatoes and basil
- Whipped goat cheese, blackberries and honey
- Pesto, fresh mozzarella and roasted tomatoes
- Warm brie, cranberry sauce and chopped pecans
- Hummus with cucumber, tomato and fresh herbs
- Roasted garlic, grated Parmesan and parsley
- Sun-dried tomato pesto with creamy goat cheese
Serve plain crostini alongside roasted garlic, herbed cheese spreads, pestos, hummus or warm dips for a simple but elegant appetizer spread. Add toppings shortly before serving to keep the toasts crisp.
Make Ahead and Storage
Crostini are an excellent make-ahead appetizer. Cool plain crostini completely, then store in an airtight container at room temperature for up to five days. Do not refrigerate, as refrigerator moisture will soften the bread. Keep moist toppings separate and add them just before serving.
How to Re-Crisp Crostini
If crostini soften, lay them in a single layer on a baking sheet and warm at 350°F (175°C) for 4–6 minutes. Cool briefly before topping.
Freezing
Freezing crostini may affect texture. Test a small batch to determine how well they reheat and hold up to your preferred toppings before freezing large quantities.
