Gluten Free Tomato and Zucchini Au Gratin (Dairy-Free)
This easy gluten free tomato and zucchini au gratin is a healthy, veggie-packed side dish with a crispy almond-coconut crumb topping and no cheese. Perfect for summer dinners or meal prep, it’s naturally dairy-free, low carb, and full of flavour.
Ingredients
- 2 medium courgettes zucchini, thinly sliced (2x courgettes approx 600g)
- 4 ripe tomatoes thinly sliced (4x tomatoes approx 300g)
- 1 handful fresh basil leaves chopped
- 2 garlic cloves finely minced
- 1 tablespoon olive oil
- For the gluten-free crumb topping:
- 24 g almond flour
- 12 g coconut flour
- 1 tablespoon nutritional yeast optional, for cheesy flavour
- 1 tablespoon coconut oil
- ⅛ teaspoon sea salt
- ⅛ teaspoon freshly ground black pepper
Instructions
- Preheat your oven to 180°C (350°F).
- Wash vegetables. An added step is to peel stripes into the courgette. This keeps some colour, texture and fibre but will reduce bitterness in the peel. Slice courgettes and tomatoes thinly.
- Finely mince garlic and chop the basil. Toss the courgette slices with the garlic, basil, and olive oil.
- In a baking dish, arrange alternating slices of courgette and tomato upright in rows or a spiral.
- Bake for 30 minutes, uncovered.
- In a bowl, mix almond flour, coconut flour, nutritional yeast, salt, pepper, and coconut oil to form a crumb.
- After 30 minutes, remove the baking dish and sprinkle the crumb evenly over the veg. Return to the oven for another 15 minutes, until golden.
- Remove from the oven. Let the dish sit for 5–10 minutes before serving so it sets slightly, and flavours deepen.
Notes
Store leftovers in an airtight container in the fridge for 2-3 days. Reheat in the oven or for best texture. Note that the crumb topping will have the best texture straight after the first bake.
The courgette and tomato base can be meal-prepped in advance and stored in the refrigerator. Simply bake when ready and top with the crumb for the final 15 minutes of baking.
I don’t recommend freezing this dish as the courgette and tomato will become too watery and soft.
