This Gluten-Free Crostini Bread is made from a homemade cottage cheese–based loaf that’s baked, cooled, sliced, and toasted to create a crisp, sturdy crostini base. It uses no yeast, no gums, and no rising time, and is designed to hold tomato and basil toppings without crumbling or turning gummy.
Most gluten-free crostini recipes rely on store-bought bread or treat the base as an afterthought. This recipe solves the bread problem first. I tested this no-yeast loaf specifically for crostini, dialing in the slice thickness, oiling, and second bake so it stays crisp on the edges and firm in the center.
I make these when I need a gluten-free appetizer I can count on. The bread holds together, the edges get golden, and the tomato basil topping stays fresh instead of soaking in. It’s a reliable recipe I come back to, especially when time is tight.
Why These Gluten-Free Crostinis Work
- Bread built for crostini: I tested the loaf specifically for slicing and toasting, so it stays crisp on the edges and firm in the center without crumbling or turning gummy.
- No yeast, no waiting: This is a true no-yeast bread, which means no rise time, no proofing, and crostinis that are ready in about 40 minutes.
- Handles juicy toppings: Tomato and basil release moisture fast, and this bread is structured to hold toppings without soaking through or falling apart.
- Simple ingredients, better texture: Cottage cheese adds moisture and protein while keeping the crumb tender—without gums, fillers, or that dry gluten-free bite.
Ingredients & Substitutions
Here is everything you need to make the no-yeast gluten-free crostini bread,
- Oat Flour: You can make your own by blending rolled oats in a food processor until fine or use storebought.
- Almond Flour: Adds moisture and structure without the gumminess of rice flour. You can swap with sunflower seed flour for a nut-free option with similar fat content and texture.
- Additional Flour Options: You can use one of these flour options in place of the flour combination in the recipe card.
| Options | w/ Almond Flour | w/o Almond Flour |
|---|---|---|
| Oat Flour | 1-1/4 cups Oat Flour + 1/2 cup Almond Flour | 1-1/2 cups Oat Flour |
| Brown Rice Flour | 1-1/3 cups Brown Rice Flour + 1/2 cup Almond Flour | 1-1/2 cups Brown Rice Flour |
| Gluten-Free Flour Blend | 1-1/4 cups Gluten-Free Flour + 1/2 cup Almond Flour | 1-1/2 cups Gluten-Free Flour |
| Cassava Flour | 1/2 cup Cassava Flour + 1 cup Almond Flour | Not recommended for a ‘bread’ consistency |
- Parmesan Cheese: Provides savory depth and helps create that crusty exterior. For a dairy-free version, use nutritional yeast or a dairy-free parmesan alternative.
- Baking Powder: Make sure yours is fresh (less than 6 months old) or your bread may not rise.
- Salt: I prefer fine sea salt, but kosher salt works well too (just use a bit more).
- Cottage Cheese: The secret ingredient that adds protein, moisture, and helps achieve that tender crumb. Blend until smooth before using. You can substitute with Greek yogurt.
- Egg: For an egg-free version, a flax egg (1 Tbsp ground flaxseed + 3 Tbsp water) works surprisingly well.
- Sesame Seeds: Add authentic French bread appearance and nutty flavor to the crust. You can substitute with poppy seeds, everything bagel seasoning, or omit entirely.
- Egg White: Creates that shiny, bakery-style golden crust. Brushing with olive oil or dairy-free milk works as an alternative.
- Garlic: A little goes a long way to infuse flavor into the crostini. For a low-FODMAP version, skip it or use garlic-infused olive oil instead.
- Mozzarella: I like using fresh mozzarella slices or pearls because of how well they melt. You can also use a dairy-free mozzarella that melts well, like Miyoko’s or Violife.
- Cherry Tomatoes: These bring the juicy sweetness! Grape tomatoes or chopped tomatoes also work if that’s what’s in your fridge.
- Fresh Basil: Adds brightness and that classic Caprese flavor. Flat-leaf parsley can work in a pinch, but basil really makes it shine.
- Balsamic Vinegar + Honey: This quick little drizzle ties everything together with sweet-tangy goodness. Maple syrup or agave are great swaps for the honey if you need it vegan.
Easily Adapt This Recipe for Any Diet
This recipe is naturally easy to tweak! Follow these simple swaps to make it gluten-free, dairy-free, or vegan while keeping the same great texture and flavor.
- Gluten-Free: The recipe is gluten-free as written—just make sure your oat flour is certified gluten-free if you have celiac.
- Dairy-Free: Use dairy-free, thick greek yogurt in place of cottage cheese and swap mozzarella for a plant-based version that melts well.
- Vegan: Combine the dairy-free swaps above with a flax egg and use maple syrup instead of honey in the glaze.

How to Make My Gluten-Free Crostini
Here are easy, detailed, step-by-step instructions that are also repeated in the recipe card at the bottom of this blog post.
Step 1: Prepare the Cottage Cheese and Preheat
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
Place 1 cup cottage cheese in a blender or food processor and blend until completely smooth. Add the egg and blend just until combined.
Step 2: Mix the Bread Dough
In a large bowl, whisk together 1-1/4 cups oat flour, 1/2 cup almond flour, 1/4 cup grated parmesan cheese, 1-1/2 teaspoons baking powder, and 1/2 teaspoon salt until well combined.
Add the blended cottage cheese and 1 egg to the dry ingredients. Mix with a wooden spoon or spatula until just combined. The dough should slightly stick to your fingers when touched. If it’s too dry, add a little milk and if it’s too wet, add a little more flour.
Step 3: Shape the Bread
Pour some oil in your hands and shape the dough into a smooth loaf on a baking sheet.
In a small bowl, lightly beat 1 egg white. Brush the top of the loaf lightly with the egg white, then sprinkle with 1 teaspoon sesame seeds.
Step 4: Bake the Loaf
Bake for 28-32 minutes, or until the crust is golden brown. Let the bread cool completely on a wire rack to allow the interior to set properly. If you slice it while it’s still warm, the center can crush and become gummy.
Step 5: Toast the Crostini
Preheat oven to 425°F (220°C). Slice the cooled loaf into 1/2-inch slices. Mix 2 tbsp olive oil with 1 minced garlic clove. Brush both sides of each slice and place on a baking sheet. Toast 5–7 minutes until golden.
Step 6: Add Mozzarella
Place a small slice or spoonful of mozzarella on each toasted crostini. Return to the oven for 1–2 minutes, just until softened.
Step 7: Finish and Serve
Top each crostini with halved cherry tomatoes. Sprinkle with salt and a little black pepper.
In a small bowl, stir together 2 tbsp balsamic vinegar and 1 tsp honey. Adjust sweetness to taste.
Drizzle each crostini with balsamic-honey glaze. Add fresh basil on top. Serve warm or at room temp.
My Expert Recipe Tips
- Let the loaf cool before slicing: I know it’s tempting, but cutting into hot bread can make the inside gummy or flatten the crumb. Letting it cool gives it time to set up properly.
- Slice the bread thick enough: I aim for about 1/2-inch slices. Thinner slices tend to crumble once toasted, and thicker slices stay soft in the middle.
- Brush both sides with oil: Gluten-free bread dries out fast. Oiling both sides helps the crostini crisp evenly instead of burning on the edges.
- Use fresh basil last: Wait to add the basil until right before serving so it stays vibrant and fresh. If you add it too early, it can wilt from the heat.
- Add toppings right before eating: This is a big one! If you assemble too far in advance, the tomato juices, fresh basil, and balsamic glaze can soften the bread. Add them just before serving for the best texture.
Delicious Serving Suggestions
- Appetizer platter: These crostinis are perfect on a party board with olives, nuts, and fruit.
- Game day snack: Serve as a gluten-free finger food for any sports night.
- With salad: I love serving these with my lemon chicken caesar salad recipe.
- A side for soup: The Italian flavors taste amazing with my marry me chicken soup.
