Quinoa & Courgette Gratin – A Healthy, Gluten-Free Vegetarian Bake
Looking for a hearty, gluten-free dish that’s both nutritious and delicious? This Quinoa & Courgette Gratin combines tender courgettes with protein-packed quinoa, baked in a creamy, cheesy flan base.
Perfect for a midweek family dinner, this vegetarian gratin is easy to prepare and offers a satisfying meal when paired with a crisp green salad. Whether you’re catering to dietary restrictions or simply seeking a wholesome recipe, this gratin is sure to become a household favourite.
This dish makes a complete meal with the added proteins of quinoa and eggs. Serve with a crunchy green salad on the side.
I used a mixture of yellow and green courgettes but you can use whichever variety you have. To speed things up, you can start cooking the onion and garlic while the quinoa is cooking.
You can replace the parmesan with cheddar cheese or gruyère. Goat cheese also makes a tasty alternative. Quinoa can be substituted for rice (I prefer brown rice), which you will also need to pre-cook.
This Quinoa & Courgette Gratin recipe serves 6-8 people. Leftovers can be reheated the next day, preferably in the microwave.
