This gooey sourdough pesto grilled cheese is the sandwich I crave when I need comfort food that feels just a little special. The mix of herby pesto, creamy mozzarella, and smoky bacon tucked into crispy golden sourdough makes every bite crave-worthy. It is the kind of grilled cheese that always vanishes fast during lunch with my family and nobody ever complains about leftovers.

The first time I made this was on a rainy afternoon when we all needed a pick-me-up. Now my youngest asks for it as a movie night treat, especially when we have soup bubbling in the kitchen.

Gather Your Ingredients

  • Sourdough bread: Thick-cut slices deliver the best crunch and hold up to fillings
  • Fresh mozzarella: For gooey melt be sure to dry the slices to avoid a soggy sandwich
  • Sun-dried tomatoes: Balance the richness with tangy depth look for ones with supple texture not too tough
  • Bacon: Crumbly and savory go for thicker strips if you like big flavor
  • Pesto: Homemade or store-bought both work as long as it packs plenty of basil and garlic
  • Butter: Soft for easy spreading on bread and a crisp finish when grilled

How to Make It

Prep the Mozzarella:
Pat mozzarella slices dry with paper towels this step prevents soggy bread and helps the cheese melt evenly
Cook the Bacon:
Fry bacon strips until crisp then blot excess grease and chop into small bits this brings smoky flavor to every bite
Assemble the Sandwiches:
Spread a generous spoonful of pesto on one side of each bread slice then layer with mozzarella sun-dried tomatoes and bacon stack the remaining bread on top with pesto facing in
Butter the Bread:

Fresh mozzarella is my favorite part of this sandwich because it gives every bite that stretchy cheese pull my kids literally cheer for. I still remember the first time my husband tried this he said it was the best grilled cheese he had ever tasted.

Flavor Boosters

Wrap leftovers tightly in foil or an airtight box and refrigerate. To reheat place the sandwich in a dry skillet over low heat and cover for a few minutes for a crisp crust. Avoid microwaving as it can make the bread chewy instead of crispy.

Serving Suggestions

Pair this grilled cheese with creamy tomato soup for a classic lunch or serve with a crisp green salad. Cut sandwiches into small squares for a party appetizer platter. A drizzle of balsamic glaze takes the flavors to another level if you want to impress guests.

Creative Twists

If sourdough is not available try a hearty country bread. For a vegetarian version skip the bacon and use grilled zucchini ribbons for extra flavor. Jarred roasted red peppers can swap for sun-dried tomatoes if you want a milder taste.

Ingredients You’ll Need

→ Bread

01 8 thick slices sourdough bread

→ Dairy

02 12 ounces fresh mozzarella cheese, thinly sliced and patted dry

→ Vegetables

03 8 sun-dried tomatoes, chopped

→ Meat

04 4 slices bacon, cooked and chopped

→ Condiments

05 4 tablespoons basil pesto

→ Fats

06 Unsalted butter, as needed for grilling

How to Make It

Step 01

Slice the mozzarella cheese into thin pieces and pat dry with a paper towel. Chop the sun-dried tomatoes and slice the cooked bacon strips into small pieces.

Step 02

Arrange four slices of sourdough bread on a flat surface. Spread one tablespoon of pesto over each slice. Layer sliced mozzarella evenly, followed by chopped sun-dried tomatoes and bacon pieces. Top each with the remaining bread slices.

Step 03

Spread a thin, even layer of butter on the outer side of each sandwich. Ensure the butter covers edge to edge for even browning.

Step 04

Preheat a large nonstick skillet or griddle over medium heat. Place sandwiches buttered side down and cook for 3-5 minutes per side, pressing gently, until crisp and golden brown and cheese is fully melted.

Step 05

Remove from heat, let stand for 2 minutes, then slice in half and serve immediately.

Extra Suggestions

  1. Patting the mozzarella dry prevents sogginess in the grilled cheese. For extra flavor, rub the skillet gently with a cut garlic clove before grilling.
