Troubleshooting
The casserole is watery after baking.
Pat the sliced zucchini with paper towels before layering and avoid adding extra liquid marinara. You can also bake uncovered for an additional 5 minutes to evaporate excess moisture.
Ground beef is undercooked.
Ensure the beef is browned fully in the skillet and reaches 160°F. If needed, continue cooking a few minutes longer before adding the sauce.
Cheese does not melt or brown.
Make sure the oven is fully preheated to 375°F and bake for the full 30 minutes. If the top is still pale, broil for 1‑2 minutes, watching closely.
Storage
Refrigerator: Store leftovers in an airtight container for 3‑4 days.

Room temperature: Do not leave at room temperature for more than 2 hours.
Make-Ahead Tips
- Assemble the casserole through step 5, cover tightly, and refrigerate up to 24 hours before baking.
- The assembled, uncooked casserole freezes well for up to 2 months; bake from frozen by adding 10‑15 minutes to the bake time.
