For this recipe, I recommend using cremini mushrooms as they add a rich, earthy flavor. However, you can also use button mushrooms for a milder taste or even shiitake mushrooms for a more unique twist.

How should I store leftovers?
Leftover Feta & Mushroom Brunch Squares can be stored in an airtight container in the refrigerator for up to 3 days. Make sure they are completely cooled before sealing to keep them fresh. They are delightful when enjoyed cold or reheated!

When you’re ready to enjoy them, simply thaw the squares in the refrigerator overnight, and reheat in the oven at 350°F (175°C) for 15-20 minutes until warmed through.

What can I use instead of cottage cheese?
If you want to skip the cottage cheese, you can replace it with Greek yogurt for a similar creaminess or leave it out altogether. You’ll still have tasty, fluffy squares! If you re looking for a dairy-free option, try using silken tofu blended until smooth.

How can I tell when my brunch squares are done baking?
The best way to check for doneness is by gently shaking the baking dish. If the center is set and does not jiggle, they are ready. You can also insert a toothpick in the center; it should come out clean or with just a few moist crumbs.

Are there any dietary considerations I should keep in mind?
Yes! If you have gluten sensitivities, this recipe is naturally gluten-free. However, if you have dairy allergies, I suggest omitting the feta and cottage cheese, or substituting them with dairy-free alternatives like cashew cream for the cottage cheese and nutritional yeast for the feta flavor. Additionally, be sure to check all packaged ingredients for potential allergens.
