1-First Step: Preheat oven to 350 degrees F and grease a quiche, pie, or casserole dish.

2-Second Step: Sprinkle a pinch of salt on the grated zucchini and let it sit briefly. Then squeeze out excess water using a clean kitchen towel or paper towels. Removing zucchini moisture is key for structure, and salt helps extraction.

3-Third Step: Whisk eggs, milk, flour, and baking powder together in a large bowl until smooth. Blending flour and baking powder into the batter creates a crustless, fluffy texture.

4-Fourth Step: Fold in the diced ham, drained zucchini, grated cheddar cheese, and a pinch of salt and black pepper. Taste matters here, because ham and cheese can be salty, so adjust for saltiness.

5-Fifth Step: Transfer the mixture to the prepared dish and spread it evenly. For a more even bake, take a moment to smooth the top so the center cooks through at the same rate.

6-Sixth Step: Bake on a foil-lined sheet for 45 minutes, until golden and set with no jiggle. Baking on a foil-lined sheet helps catch any overflow and makes cleanup easier.

7-Seventh Step: Cool for at least 10 minutes before cutting. This rest time helps everything firm up into neat slices.

8-Final Step: Serve warm or room temperature. If you are meal prepping, let it cool fully before refrigerating so it stays tender without getting watery.
