Ingredients and Equipment

Before crafting a truly memorable Sun-Dried Tomato Pesto Grilled Cheese, it’s essential to assemble all your ingredients and tools. High-quality inputs make all the difference in a dish this simple yet refined.

Ingredients

For the Sun-Dried Tomato Pesto

(Makes about 1 cup, enough for 4–6 sandwiches)

• Sun-dried tomatoes (in oil) – 1 cup, drained
  Look for jarred sun-dried tomatoes packed in olive oil; they have a rich, preserved flavor and soft texture perfect for blending.

• Fresh basil leaves – 1 cup, packed
  For classic pesto freshness and aroma.

• Garlic – 2 cloves
  Adds a pungent, savory bite.

• Pine nuts or walnuts – ¼ cup
  Pine nuts are traditional, but walnuts offer an affordable, earthy alternative.

• Parmesan cheese (grated) – ½ cup
  Adds saltiness, depth, and body to the pesto.

• Olive oil – ½ to ⅔ cup
  Extra virgin preferred; adjust to desired consistency.

• Lemon juice – 1 tbsp
  Brightens the pesto and balances the richness of the tomatoes and cheese.

• Salt – ½ tsp (or to taste)
  Essential to bring out the full flavor of the ingredients.

• Cracked black pepper – ¼ tsp
  Optional, for a subtle heat.

For the Grilled Cheese Sandwich

(Makes 2 sandwiches; scale up as needed)

• Bread – 4 slices
  Choose hearty, bakery-quality bread like sourdough, ciabatta, or rustic white. The crust should hold up to grilling and moisture from the pesto.

• Cheese – 1 to 1½ cups, grated or sliced
  Recommended blends:

  • Mozzarella (for melt and stretch)

  • Fontina (for creaminess)

  • Sharp white cheddar (for tang)

  • Gruyère (for nuttiness)

• Butter – 2–3 tbsp
  For spreading on the bread exterior. Salted or unsalted based on preference.

• Optional Add-Ins:

  • Fresh spinach or arugula – for a green, peppery contrast

  • Roasted red peppers – sliced, for a smoky-sweet addition

  • Caramelized onions – for depth and sweetness

  • Prosciutto or pancetta – thinly sliced, if not making it vegetarian

  • Fresh mozzarella slices – for extra creaminess in the center

Equipment Needed

• Food processor or blender – For making pesto.

• Chef’s knife and cutting board – For prepping ingredients.

• Grater – For cheese and Parmesan.

• Cast iron skillet, nonstick pan, or griddle – For grilling sandwiches.

• Spatula – For flipping.

• Mixing bowl and spoon – Optional, for tossing optional greens or prepping ingredients.

• Bread knife – For slicing bread evenly.

Step-by-Step Instructions

Step 1: Make the Sun-Dried Tomato Pesto

This pesto is the soul of the sandwich—it delivers bold flavor with very little effort.

1. Prepare the ingredients.

• Drain the sun-dried tomatoes from their oil but retain a tablespoon or two of the oil—it’s packed with flavor and can replace some of the olive oil.

• Toast the nuts (optional but recommended): In a dry skillet over medium heat, toast pine nuts or walnuts for 2–3 minutes until fragrant. Be careful not to burn them.

2. Blend the pesto.

• In a food processor, combine:

  • 1 cup sun-dried tomatoes

  • 1 cup fresh basil leaves

  • 2 garlic cloves

  • ¼ cup toasted nuts

  • ½ cup Parmesan cheese

  • 1 tbsp lemon juice

  • ½ tsp salt

  • ¼ tsp black pepper

• Pulse 4–5 times to begin breaking everything down.

3. Add the oil gradually.

• With the processor running, slowly drizzle in ½ cup olive oil (including some reserved tomato oil if using) until a thick paste forms.

• Stop and scrape down the sides to ensure even blending.

• Adjust consistency: For a looser spread, add up to 2–3 tbsp more olive oil. For a chunkier pesto, pulse briefly and stop before it becomes too smooth.

4. Taste and adjust.

• Add more lemon juice for brightness, cheese for saltiness, or olive oil to mellow out sharpness. Set aside in a sealed container if not using immediately. This pesto stores well in the fridge for 5–7 days.

Step 2: Assemble the Sandwiches

The layering is just as important as the grilling. Even distribution ensures every bite is balanced.

1. Prep your cheese.

• Grate or slice your chosen cheeses. A mix of mozzarella and sharp cheddar is a great starting point, with optional additions like Fontina or Gruyère for extra nuance.

2. Butter the bread.

• Spread butter evenly on one side of each slice. This will be the exterior side that contacts the pan.

• Optional: Mix a pinch of garlic powder or grated Parmesan into the butter for extra flavor.

3. Assemble in layers.

• Place one slice, butter-side down, on a clean surface or plate.

• Spread a generous spoonful of sun-dried tomato pesto on the interior (unbuttered) side.

• Add a layer of cheese over the pesto. Distribute it evenly to the edges for consistent melt.

• Add optional extras now (greens, peppers, onions, meat).

• Top with a second slice of bread, buttered side up.

4. Press gently.

• Gently press the sandwich together to help seal the layers without squeezing out the filling.

Step 3: Grill to Golden Perfection

This is where the magic happens. The right temperature and timing make all the difference.

1. Preheat your skillet.

• Heat a nonstick or cast iron pan over medium-low to medium heat. Too hot and the bread burns before the cheese melts.

2. Add the sandwich to the pan.

• Carefully place the sandwich onto the hot skillet. You should hear a soft sizzle—not a loud sear.

3. Cover loosely.

• Use a lid or foil tent to cover the pan. This traps heat and encourages the cheese to melt evenly.

4. Cook slowly and evenly.

• Grill the sandwich for 3–5 minutes on the first side. Check occasionally to ensure it’s not browning too fast.

• When the bottom is golden and crisp, flip gently with a spatula.

• Grill the second side for another 3–4 minutes until the cheese is fully melted and the bread is evenly browned.

5. Remove and rest.

• Transfer to a cutting board and let it rest for 1 minute before cutting. This allows the cheese to set slightly and avoids losing it all to the plate.

6. Slice and serve.

• Cut in half diagonally or straight down the middle, depending on your aesthetic. Serve immediately while still warm and melty.
