This bacon guacamole grilled cheese sandwich takes the classic comfort food to a whole new level by combining crispy bacon, creamy guacamole, and gooey melted cheese between perfectly toasted sourdough. The combination creates a flavor explosion that's both indulgent and irresistible.
The optional tortilla chips add an unexpected crunch that takes this sandwich from great to extraordinary. I discovered this trick during a late-night cooking session when I accidentally dropped a chip into my sandwich prep and now I never make it without that extra texture.
Ingredients
- Salted butter: at room temperature creates that perfect golden crust
- Sourdough bread: provides sturdy structure and tangy flavor
- Colby jack cheese: melts beautifully while offering both mild creaminess and slight sharpness
- Guacamole: adds creamy richness and a fresh contrast to the savory elements
- Crispy bacon: delivers smoky depth and satisfying texture
- Tortilla chips: offer an optional but highly recommended crunchy element
Step-by-Step Instructions
- Prepare The Skillet:
- Heat your skillet over medium heat until warm but not smoking hot. This ensures even cooking without burning the bread before the cheese melts.
- Butter The Bread
- Spread room temperature butter generously across one side of each bread slice. Make sure to cover edge to edge for that perfect golden crust.
- Assemble The Sandwich
- Place one slice bread butter side down on a clean surface or directly in the skillet. Layer half the cheese first to create a barrier that prevents the guacamole from making the bread soggy. Add the guacamole, bacon, chips if using, and remaining cheese. Top with second bread slice butter side up.
- First Side Grilling
- Cook the sandwich undisturbed for 2 to 4 minutes. Look for a golden brown color on the bottom and the cheese beginning to melt. Resist the urge to press down as this squeezes out precious melted cheese.
- Flip And Finish
- Carefully flip the sandwich using a spatula that supports the entire sandwich. Cook for another 2 to 3 minutes until the second side is golden brown and all cheese is wonderfully melted.

The first time I made this sandwich was for my brother who claimed he hated guacamole. After one bite, he immediately asked for the recipe and now makes it regularly for his own family. The bacon completely transforms how the avocado flavors present themselves.
Make-Ahead Options
You can prep components separately for quick assembly. Cook bacon in advance and store in the refrigerator for up to three days. Prepare guacamole with extra lime juice to prevent browning and keep refrigerated for one day. When ready to eat, simply assemble and grill for the ultimate fresh experience.
Ingredient Substitutions
Bread alternatives work beautifully in this recipe. Try Texas toast for a thicker sandwich, ciabatta for a rustic texture, or whole grain for added nutrition. For the cheese, substitute pepper jack for a spicy kick, sharp cheddar for stronger flavor, or mozzarella for extra stretchiness. Plant based bacon and vegan cheese can create a satisfying vegetarian version.

Serving Suggestions
This sandwich pairs wonderfully with light sides that balance its richness. Consider serving alongside a simple green salad with vinaigrette, tomato soup for classic comfort, or sweet potato fries for an elevated diner experience. For beverages, try an ice cold beer, sparkling water with lime, or unsweetened iced tea to cut through the richness.
