Building Your Sandwich
  • Spread ingredients across the whole bread for taste in every bite
  • Blot tomato slices with paper towel so bread stays crisp
  • Squish sandwich slightly so everything sticks together
Getting the Grill Just Right
  • Use medium-low fire so cheese gets all melty inside
  • Push down gently with your spatula for even browning
  • Keep an eye on it to avoid burning the bread
Getting That Perfect Cheese Pull
  • Put a lid on briefly to help cheese melt thoroughly
  • Turn heat up or down as needed if browning too fast

When I was little, grilled cheese meant comfort. This grown-up sandwich keeps that warm feeling but adds fancy flavors I love now.

When smooth cheese meets fragrant pesto, you get a sandwich that's both snuggly and exciting at the same time.

You'll love how each mouthful gives you that crunchy outside and gooey inside, with bright pesto flavor running through it all.

Adding tomatoes brings a fresh juiciness and tangy kick that works perfectly with the rich cheese.

I've tried tons of different versions, and this recipe nails the perfect balance between old-school comfort and fancy grown-up taste.

Keeping Leftovers Fresh

Make the most of any extras:

  • First wrap in parchment then cover with foil
  • Warm up in a skillet instead of microwave to keep it crispy
  • Keep ingredients apart if making ahead
  • Let cold stuff sit out a bit before making your sandwich

Fixing Common Problems

When bread gets too dark too fast:

  • Turn down the heat and go slower
  • Cut bread a bit thicker
  • Watch the first side carefully
  • Start with an unheated pan

When cheese won't melt right:

  • Put the lid on for half a minute
  • Cut or grate cheese thinner
  • Let cheese warm up before using
  • Grate it yourself instead of buying pre-shredded

Ingredients

→ Main Ingredients

01 4 slices of thick sourdough
02 2 tablespoons of softened butter
03 4 slices of crispy bacon (if you'd like)
04 A couple of vine-ripened tomatoes, thinly sliced
05 Pesto sauce—2 tablespoons
06 4 ounces fresh mozzarella, cut into slices

Instructions

Step 01

Start cooking the bacon in a cool pan over medium heat. Once crunchy, move to a plate with a paper towel—leave the grease behind.

Step 02

Take the bread and spread pesto across each piece. Layer on the mozzarella, then the tomato slices, then bacon (if you're using it). Finish by placing another bread slice on top, pesto side in.

Step 03

Preheat your skillet to medium. Butter the outside of the sandwiches and put them in the pan, butter touching the skillet first. Cook 3-4 minutes ’til they’re golden brown underneath.

Step 04

Spread butter on the uncoated side, flip them over, and cook another 2-3 minutes. The bread should crisp up, and the cheese will get nice and melty. Let cool for a minute or two before slicing.

Notes

  1. Adding bacon is totally up to you
  2. A crusty loaf works best for this
  3. Dry off mozzarella before adding it in
