Tips & Substitutions

For a creamier texture, consider adding a little cream cheese or sour cream to the mixture. If you don't have frozen spinach, fresh spinach can be used; just sauté it until wilted before adding. You can substitute Cheddar cheese with a mix of your favorite cheeses like mozzarella or feta for a different flavor profile. Season the mixture with garlic powder or nutmeg for an extra kick.

Serving Suggestions

These Spinach Squares make a delightful appetizer for parties or family gatherings. Serve them warm with a side of marinara sauce for dipping, or pair with a fresh salad for a light meal. They also pair beautifully with Mary'S Dessert Cookies for a sweet finish to your gathering.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply place the squares in a preheated oven at 350°F for about 10 minutes, or until warmed through. Alternatively, you can microwave them for about 1-2 minutes, but they may lose some crispness.

Frequently Asked Questions

Can I use fresh spinach instead of frozen?

Absolutely! If using fresh spinach, you'll need about 10 ounces. Sauté the fresh spinach in a little olive oil until wilted, then drain before adding it to the mixture. This will enhance the flavor and ensure the right texture.

What can I serve these with?

These squares can be served as finger food at parties, or as a side dish. They pair nicely with a crisp green salad or a tangy dipping sauce. For a heartier meal, serve alongside grilled chicken or fish.

Can I make these ahead of time?

Yes, you can prepare the mixture a day in advance and store it in the refrigerator. Just remember to bake them fresh the day you plan to serve for the best texture and taste. Leftovers can easily be reheated.
