  • 1–1½ cups fresh mozzarella, sliced or shredded
  • 2–3 tablespoons butter

Optional Add-Ins

  • Fresh basil leaves 🌿
  • Garlic powder
  • Black pepper

Best Bread for Grilled Cheese

Sourdough

  • Crispy crust
  • Slight tanginess
  • Best structure for fillings

Brioche

  • Soft and slightly sweet
  • Rich flavor

Whole Grain

  • Heartier texture
  • Slight nutty taste

Sourdough is often the best balance for crispness and structure.


Step-by-Step Instructions

Step 1: Prepare Ingredients

Slice:

  • Avocado
  • Tomato
  • Mozzarella

Pat tomatoes dry slightly to reduce moisture.


Step 2: Butter the Bread

Spread butter on one side of each bread slice.

This creates a golden, crispy exterior when cooked.


Step 3: Assemble the Sandwich

On the unbuttered side, layer:

  1. Mozzarella
  2. Tomato slices
  3. Avocado slices
  4. Optional basil or seasoning
  5. More mozzarella (optional for extra melt)

Top with second slice of bread, buttered side facing out.


Step 4: Heat the Pan

Heat a skillet or griddle over medium heat.

Low-to-medium heat ensures even melting without burning.


Step 5: Cook the Sandwich

Place sandwich in pan and cook for:

  • 3–4 minutes per side

Press lightly with spatula for even browning.

Flip once golden brown.


Step 6: Melt and Finish

Cook until:

  • Bread is crispy and golden
  • Cheese is fully melted
  • Avocado is warm and creamy

Step 7: Slice and Serve

Let rest for 1–2 minutes before slicing.

Cut diagonally for best presentation.


Tips for the Perfect Grilled Cheese

Use Ripe Avocado

Soft but not mushy for best texture.

Don’t Overload Tomatoes

Too much moisture can make bread soggy.

Cook on Medium Heat

Prevents burning before cheese melts.

Dry Tomatoes Slightly

Improves sandwich structure.

Add Cheese on Both Sides

Helps “glue” ingredients together.
