Frequently Asked Questions

Can I make the spinach casserole with feta cheese ahead of time?

Absolutely! You can assemble the casserole a day in advance and store it, covered, in the refrigerator. When you're ready to bake, simply pop it in the oven, but you might need to add 5-10 minutes to the baking time as it will be starting cold.

Just think of it as your own personal 'Bake Off' technical challenge, but you've got a head start!

What's the best way to store leftover spinach casserole with feta cheese?

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, you can microwave individual portions or reheat the entire casserole in the oven at a lower temperature (around 300°F/150°C) until warmed through.

Think of it like leftovers from Sunday roast; always good for a second showing!

I'm not a huge fan of feta. What can I substitute in my spinach casserole with feta cheese?

No worries, there are options! If you find feta a bit too strong, try using ricotta cheese instead. It'll provide a similar creamy texture but with a milder flavour. You could even use a blend of mozzarella and Parmesan for a different, cheesier profile.

Can I use fresh spinach instead of frozen for my spinach casserole with feta cheese?

You certainly can! You'll need about 1 pound of fresh spinach to equal the amount in a 10-ounce package of frozen. Make sure to wash the fresh spinach thoroughly and sauté it until it wilts down before adding it to the casserole mixture.

Remember to still squeeze out the excess water, as fresh spinach contains even more moisture than the frozen kind. It's a bit more work, but the flavour is worth it!

Is there anything I can add to the spinach and feta casserole to make it a complete meal?

Great question! To make it more substantial, consider adding some cooked chicken or sausage to the spinach mixture. You could also add some cooked rice or quinoa for extra texture and nutrients. Adding these ingredients transforms this side dish into a hearty, filling main course.

It's like turning tea and biscuits into a proper afternoon tea with sandwiches upgrade complete!

How can I make this spinach casserole with feta cheese healthier?

There are a few tweaks you can make. Use low-fat sour cream and skim milk to reduce the fat content. You could also increase the amount of spinach and reduce the amount of cheese slightly.

Adding whole wheat flour instead of all-purpose, or adding chopped veggies like mushrooms or zucchini would also boost nutritional value without sacrificing flavour. Small changes can make a big difference!
