Common Mistakes To Avoid

Using thick zucchini slices: Thin slices cook faster and turn tender. Thick slices may stay firm and watery.

Not draining the beef: Extra grease can make the casserole oily. Always drain well after browning.

Skipping the rest time: Letting it rest helps the creamy layers firm up. If you cut too soon, it may fall apart.

Tips For Success

If your zucchini seems very watery, sprinkle it lightly with salt and let it sit for 10 minutes. Pat dry with paper towels before layering.

For more flavor, add a pinch of paprika or red pepper flakes to the beef. It gives a gentle kick without overpowering the dish.
