Pesto Grilled Cheese Perfection (Print Version)

# Ingredients:

→ Core Components

01 - 4 slices thick-cut bread (such as sourdough or Italian loaf)
02 - 30 grams softened unsalted butter
03 - 30 grams fresh basil pesto
04 - 4 slices whole milk mozzarella cheese
05 - 4 slices sharp cheddar cheese

# Instructions:

01 - Generously spread softened butter on one side of each bread slice, ensuring even coverage for a golden crust.
02 - On the opposite, unbuttered side of two bread slices, spread half of the basil pesto. Repeat this for the remaining two slices.
03 - Evenly layer two slices of mozzarella cheese followed by two slices of sharp cheddar cheese on the pesto-coated side of two bread slices. Top with the remaining two bread slices, ensuring the buttered side faces outwards.
04 - Heat a nonstick skillet or griddle over medium heat. Carefully place the assembled sandwiches in the hot skillet. Cook for 3 to 4 minutes per side, or until the bread is perfectly golden brown and the cheeses are thoroughly melted and bubbling.
05 - Remove the grilled sandwiches from the skillet and allow them to rest for 1-2 minutes. This brief resting period helps the cheese set. Slice each sandwich diagonally and serve immediately, either on its own or alongside a warm bowl of tomato soup.

# Notes:

01 - For an intensified flavor, incorporate a small pinch of red pepper flakes directly into the basil pesto before spreading.
02 - Experiment with different cheese varieties such as provolone, fontina, or smoked gouda to develop a unique taste profile.
03 - Enhance texture and freshness by adding thinly sliced ripe tomatoes or roasted red peppers to the sandwich filling.
04 - To create a vegan version, substitute all dairy products with plant-based butter, vegan pesto, and vegan cheese alternatives.
05 - For an exceptionally crispy exterior, brush the outer surfaces of the bread with a thin layer of mayonnaise instead of butter before grilling.
