Tips on Making Zucchini Potato Casserole

While casseroles are easy to make, there are still quite some pitfalls to avoid. Make perfect zucchini potato casserole every time with the help of these valuable tips.

  • First, use the right size of baking dish according to the recipe. If you use a pan that’s too big, the casserole will cook faster. On the other hand, with a smaller one, it might need more time to get fully cooked through. Keep an eye on it. Also, make sure that the pan heatproof and has been greased so that the ingredients won’t stick.
  • Secondly, add other veggies to make it even healthier. You can add some diced bell pepper, chopped green onion, minced garlic cloves, carrots, or corn kernels, for instance.
  • Do not use watery ingredients like cucumbers, lettuce, or pickles and extra-moist ham. Otherwise, your casserole will turn out too watery. 
  • Toss in your leftovers! This casserole dish gives your leftover rotisserie chicken or roasted zucchini and potatoes a good use. So if you’ve got some bacon, turkey, or barbecue pork, you can use them for the protein instead.
  • Season it with different dried or fresh herbs like oregano, dill, rosemary, Italian seasoning, or use an Herbs de Provence blend. In the same way, you can add a dash of cayenne or chili flakes if you like it spicy.
  • Make it creamy by adding a splash of fresh cream or milk. Additionally, you can also use other types of cheese like cheddar, blue, gouda, and parmesan cheese.

Frequently Asked Questions

How do you get the bitterness out of zucchini?

First and foremost, fresher and younger ones might not be bitter at all. Zucchinis just tend to become more bitter as they get older and develop bigger seeds. To draw the bitterness out, first, slice them. Then, you can either salt the sliced zucchini or soak them in salted water for at least 30 minutes. Use 2 teaspoons of salt for every liter of water. This will also help draw out moisture, making them less watery. Be sure to rinse out the salt before cooking.

How do you fix a mushy casserole?

Your zucchini potato casserole might turn out mushy if the ingredients used are too watery. It’s easy to fix it. Just start by making a slurry by mixing ¼ cup of milk with 1 tablespoon of cornstarch. Combine this slurry into the mushy casserole. Then bake it again for 10 to 15 minutes or until the mixture boils. The cornstarch will thicken the mixture once it boils.

How to store zucchini potato casserole?

This ham, potato, and zucchini casserole is best consumed immediately. But if you plan to make it ahead, you can store it in an airtight container in the fridge and it’ll stay good for up to 5 days.
