A diet without dairy cheese is far from boring. This dairy-free roasted grape crostini is proof. Baguette slices are toasted with olive oil, topped with creamy ricotta style spread (yes, it’s dairy-free!), and finished with balsamic roasted grapes and onion. It’s a taste and textural delight that you can enjoy for a small plate night, or serve as an appetizer to any guest, whether they are dairy free or not.

This Dairy-Free Roasted Grape Crostini is Ready for your Spread
This creative appetizer was an entry in one of our recipe contract tests contests that we held nearly a decade ago. It was shared with us by Emily Vallozzi. We’ve recently updated her recipe with additional information, and have a few recipe notes below.
- Baguette – Most baguettes, whether fresh from the bakery or taken and bake, are dairy free by ingredients. But of course, always check the label to be sure. I have seen a baguette or two that contained milk over the years. If you have gluten free needs, look for brands like Udi’s (contains egg), or Schar (contains soy).
- Olive oil – Emily uses extra virgin olive oil, which is common in crostini recipes. If you’re concerned about high heat cooking with this oil, you can use a regular olive oil for cooking. Other baking oils, like canola oil, grapeseed oil, or avocado oil would likely work well as alternatives.
- Vinegar – Balsamic vinegar is key in this recipe. If you must, you can substitute red wine vinegar. Wouldn’t use another vinegar like apple cider vinegar or white vinegar. Those are a bit too harsh for this recipe.
- Salt – If you need to reduce your sodium intake, you can lower the salt in this recipe. We find it still quite delicious with 1/2 teaspoon salt. You can always sprinkle on a little coarse salt if you feel it’s lacking in flavor.
- Grapes – Use seedless red grapes. You can substitute seedless green grapes, or use both types for color and flavor contrast.
- Onion – Red onion is ideal for this recipe, but a yellow onion or sweet white onion will work if that’s what you have on hand.
- Herbs – Emily chooses fresh thyme for garnish, but other herbs pair nicely with these ingredients, too. Fresh rosemary, basil, or chives are great alternatives.
- Other Garnish – We think this dairy-free roasted grape crostini begs to be sprinkled with a little freshly ground black pepper. Some people also like a drizzle of sweet balsamic glaze, honey, or maple syrup.
