Spices and Herbs

01- Black Pepper

Being the universal seasoning, black pepper essentially teams up with salt in this dish. Its earthy, woody and peppery undertones get along with salt and season the eggs when they are beaten.

Thanks to the versatility of this spice, there’s no exact amount that should go into the recipe. But it always depends on the taste preference of each person. However, this is apparently the only spice that is considered to be a staple spice in posh squash.

02- Garlic Powder

Garlic powder is not a staple in this dish. But its unique pungency and intense flavor notes give an incredible kick to the vegetables. This spice complements the creamy texture of this meal and gets along well with onions and eggs.

This spice has the ability to stand up alone, and a small amount can go a long way in a particular meal. Therefore, garlic powder is always used in pinches in posh squash in order to prevent its strong taste from overpowering the overall flavor of the dish.

03- Thyme

Dried thyme has the amazing ability to complement the delicate creaminess of this dish. Just like garlic powder, thyme is also not a staple. But it still offers a unique herbal flavor and balances between earthy, savory, and sweet notes.
This herb can be added to the beaten egg mixture so that its flavor will be well-infused into the dish. Thyme complements onions, mayonnaise, zucchini, summer/butternut squash, and cheese.

Other Posh Squash Ingredients

The recipe of this dish could vary slightly depending on the person. As mentioned previously, some people make this casserole only with zucchini, while most use  both zucchini and butternut/summer squash. However, the variety of squash used depends on personal preferences.

Besides the spices and herbs mentioned in the previous section, the following ingredients are other main elements of this dish:

  • Zucchini
