Tips
Slice zucchini evenly for consistent cooking.
Salt zucchini lightly and let sit 10 minutes to reduce moisture.
Pat zucchini dry to avoid a watery bake.
Use lean beef to keep it lighter.
Simmer sauce to deepen flavor before baking.
Don’t overload with sauce to prevent sogginess.
Use a glass or ceramic baking dish for even heat.
Broil for 2–3 minutes at the end for a golden top.
Let the bake rest before cutting to hold shape.
Add fresh herbs after baking for brightness.
