Ingredients
Method
- Preheat your oven to 350°F (177°C) and lightly grease a 9x13 inch (23x33 cm) baking pan with a drizzle of olive oil.
- In a large mixing bowl, beat the 4. 0 eggs (210g) until well combined, then whisk in the 2.0 cups (473ml) of tomato puree, garlic, olive oil, herbs, and sea salt.
- Pour approximately 0.66 cups (157ml), or one-third of the egg mixture, into the prepared baking pan and spread it evenly until the bottom is fully covered.
- Arrange a layer of sliced zucchini (approx. 16 oz / 453g) over the mixture, wiggling the slices slightly so they settle into the liquid.
- Pour another one-third of the egg mixture over the zucchini, then add the remaining 16 oz (453g) of zucchini slices in a second layer.
- Top the dish with the remaining egg mixture, ensuring all zucchini is covered, and sprinkle with nutritional yeast if you are using it.
- Bake in the center of the oven for 45 minutes, or until the center is firm to the touch and the edges are slightly golden.
- Remove the Zucchini Frittata from the oven and let it rest for 5 minutes before cutting into even squares to serve.
Salt and Drain: If your zucchini seems particularly watery, toss the slices with a pinch of salt and let them sit in a colander for 10 minutes before layering. Pat them dry to ensure your Zucchini Frittata has a firm, pizza-like texture rather than being soggy.
Uniform Slicing: Use a mandoline slicer to get even, thin rounds. This ensures that every layer of your Zucchini Frittata cooks at the same rate, preventing some pieces from being crunchy while others are mushy.
The "Wiggle" Technique: Don't skip the step of wiggling the zucchini into the egg mixture! This helps the liquid fill all the gaps between the slices, creating a cohesive, structural bake that won't fall apart when sliced into squares.
Herb Freshness: While dried herbs work in a pinch, using fresh oregano and basil makes a world of difference. The aromatic oils in fresh herbs pair beautifully with the tomato puree to give this dish a truly gourmet flavor profile.
