Toaster Oven Crostini

Toaster Oven Crostini are little baguette slices brushed with olive oil and baked until golden and crispy. Add your favorite toppings for an easy appetizer!

Since it’s only the two of us I usually make a small batch of crostini using half a small baguette. If you need more little toasts, feel free to double or triple the ingredients. 

Recipe Ingredients

Bread: A crusty French baguette or rustic Italian loaf are good options. And don’t worry about freshness, like toaster oven croutons and bagel chips, day-old (aka stale) bread works great (for this post I used a leftover loaf of our toaster oven bread).

Oil: We used Olive Oil. For a fun variation try a flavored oil like roasted garlic or rosemary. Avocado oil works too and if you’re trying to cut calories you can use an oil spray instead. 

Kosher Salt or Sea Salt: Pairs wonderfully with olive oil. 

How to Make Crostini in the Toaster Oven  

1. Slice the bread on an angle into 1/4-inch thick pieces. Then lay the pieces on a rimmed sheet pan. 

2. Brush each slice with a little oil. Flip them over, brush with oil, and top with a sprinkle of salt. 

3. Bake in a 375°F toaster oven (or 350°F if you’re using a convection toaster oven) until the bread is golden, toasty, and no longer chewy in the middle.  

This should take about 10 to 15 minutes. But like most things, it will vary depending on your oven and the type of bread used.  

4. Allow the toasts to cool completely on the pan before adding your favorite toppings.

Can You Use The Toast or Broil Settings? 

There are a lot of ways you can bake crostini in a toaster oven. Some are definitely better than others. 

• While the TOAST, BAGEL, and BROIL settings did an okay job browning and crisping the edges, the middles were still quite chewy. 
• Conversely, the BAKED crostini were crisped throughout and had significantly better flavor. 

Also, the toasted and broiled pieces got soggy the next day. While the baked pieces we stored were still crisp (even after 5 days!). 

Recipe Tips and Variations 

Garlic Rubbed: To give the toasts some extra oomph, rub them with half a peeled garlic clove while they’re still a little warm. 

Seasonings: Try sprinkling the bread with dried herbs or spices before baking. Here are a few of our favorites:

• Dried Thyme or Rosemary 
• Za’atar (Not familiar with this delicious spice blend? The Mediterranean Dish breaks it down in this What is Za’atar post.)  
• Italian Seasoning Blend
• Smoked Paprika (great for dipping in a bowl of Vegetarian Split Pea Soup) 

What can you top crostini with?

From dips and spreads to fresh fruit and veggies your options are endless. Here are a few of our favorite toppings:

• Hummus
• Fruit jams and spreads like our balsamic roasted cranberries
• Fresh tomatoes or Bruschetta
• Tapenade
• All the cheeses (especially goat cheese, ricotta or cottage cheese, baked Brie, or these adorable mini cheese balls)

Can you make Crostini ahead of time?

You sure can! Untopped crostini can be stored at room temperature in a covered container for 3 to 5 days. See the recipe notes for tips on reviving the toasts if they’ve softened.
