Ingredients

  • 6 to 8 bread slices (not fresh)
  • 1/2 cup mayonnaise
  • 1 medium onion, finely chopped
  • Parmesan cheese

Instructions

  1. Remove crust from bread slices and cut each into four pieces.
  2. Mix mayonnaise with finely chopped onion.
  3. Spread the mayonnaise mixture on each bread square.
  4. Place the bread squares on a baking sheet.
  5. Sprinkle with Parmesan cheese on top.
  6. Broil until golden brown, watching carefully to prevent burning.

Tips & Substitutions

For a richer flavor, consider using homemade mayonnaise or adding garlic powder to the mixture. If you don't have Parmesan cheese, you can substitute with Pecorino Romano or a blend of Italian cheeses. Ensure the bread slices are slightly stale for the best texture, as fresh bread can become too soggy. If you like a bit of spice, add crushed red pepper flakes to the mayonnaise mixture.

Serving Suggestions

These Parmesan squares make a delightful appetizer or snack, perfect for gatherings. Serve them alongside a fresh salad or as part of a cheese platter. They pair beautifully with Orange Jelled Salad for a refreshing contrast. For a heartier option, consider serving them with a warm bowl of soup or chili.

Storage & Reheating

Store any leftover Parmesan squares in an airtight container in the refrigerator for up to 2 days. To reheat, place them on a baking sheet and warm in a preheated oven at 350°F (175°C) for about 10 minutes, or until heated through. Avoid microwaving, as it can make the bread chewy.

Frequently Asked Questions

Can I make these Parmesan squares ahead of time?

Yes, you can prepare the squares in advance by assembling them and placing them on a baking sheet. Cover with plastic wrap and refrigerate. When ready to serve, simply broil them for a few minutes until golden brown.

What types of bread work best for this recipe?

Stale bread works best for Parmesan squares as it holds up better to the toppings. You can use white bread, sourdough, or even whole grain. Just avoid fresh bread, as it can become too soft when broiled.

Can I add other toppings to the squares?

Absolutely! Feel free to experiment by adding toppings like chopped herbs, cooked bacon bits, or diced tomatoes on top of the Parmesan cheese before broiling. These additions can elevate the flavor and make the dish even more enjoyable.
