Let’s get this delicious Zucchini Pizza Casserole Recipe in the oven! It’s a straightforward process that yields incredible results. Here’s how to make this delightful dish:
- Step 1: Start by preheating your oven to 375°F (190°C). While the oven heats up, lightly grease a 9×13 inch baking dish. This prep ensures nothing sticks.
- Step 2: If you’re adding meat, brown your ground beef or Italian sausage in a skillet over medium heat. Make sure to drain any excess grease really well.

- Step 4: Now, let’s assemble! Spread half of the thinly sliced zucchini evenly across the bottom of your prepared baking dish.
- Step 5: Spoon half of the marinara sauce mixture over the zucchini layer.
- Step 6: Add half of your cooked meat (if using) over the sauce, then sprinkle half of the 2 cups shredded mozzarella cheese on top.
- Step 7: Repeat the process: layer the remaining zucchini slices, followed by the rest of the sauce, meat, and the remaining mozzarella cheese.
- Step 8: Finish by sprinkling the 1/4 cup grated Parmesan cheese evenly over the top layer of mozzarella.
- Step 9: Bake for 25-30 minutes. You’re looking for the zucchini to be tender when pierced with a fork and the cheese to be gloriously melted and bubbly. The aroma will let you know it’s almost ready!
- Step 10: Once out of the oven, let this amazing how to make Zucchini Pizza Casserole dish rest for about 5-10 minutes before serving. This helps everything set up perfectly.

One of the best things about this Zucchini Pizza Casserole Dinner is how well it stores and reheats, making it perfect for meal prep or enjoying leftovers. Once your casserole has cooled completely, cut it into individual portions. Store these portions in airtight containers. You can keep them in the refrigerator for about 3 to 4 days.

This method helps revive the flavors and textures, making it taste almost as good as when it was fresh.
