This luxurious avocado bacon grilled cheese sandwich takes the classic comfort food to new heights with creamy California avocado and crispy bacon. The combination creates a perfect harmony between the sharp melted cheese, buttery avocado, and savory bacon all encased in golden, crispy bread.

I created this recipe during a rainy weekend when my family wanted something comforting yet special. The first time I served these sandwiches alongside tomato soup, they disappeared so quickly I had to make a second batch right away.

  • Seeded whole grain bread: Whole grain adds nutty flavor and texture, though any bread works beautifully
  • Cheese slices: Cheddar, gruyere, or jack all work wonderfully, providing that essential gooey melt
  • Fresh California avocado: Provides creamy richness and healthy fats that balance the sharp cheese
  • Crispy bacon: Adds savory crunch and smoky depth that elevates this sandwich beyond ordinary
  • Butter: Creates that golden exterior and classic grilled cheese flavor
  • Mayonnaise: Secret ingredient that ensures perfect browning and adds subtle tanginess
Prepare the base:
Preheat your sandwich maker or skillet. Place one slice of cheese on the first piece of bread, creating your foundation layer. The cheese acts as a barrier to prevent the bread from becoming soggy from the avocado.
Add the avocado:
Arrange avocado slices over the cheese, leaving a small border around the edges. This strategic placement ensures the cheese seals around the avocado when melted, locking in the creamy goodness and preventing it from sliding out while eating.
Complete the layers:
Top with the second cheese slice, allowing it to blanket the avocado completely. Add the crispy bacon pieces, creating a savory middle layer that will provide textural contrast to the creamy components.
Prepare the spread:
Combine equal parts melted butter and mayonnaise in a small bowl. This magic mixture creates the perfect exterior texture while adding subtle flavor depth that butter alone cannot achieve.
Cook to golden perfection:
Spread half the butter-mayo mixture on the exterior of one bread slice before placing it into your preheated cooking surface. Add the remaining spread to the top slice. Cook until deeply golden and the cheese has melted completely, about 2-5 minutes.
Serve immediately:
Transfer to a cutting board, slice diagonally, and serve while hot. The perfect grilled cheese must be enjoyed immediately when the cheese is at peak meltiness and the exterior is at its crispiest.

The first time I served this sandwich at a casual weekend gathering, my brother-in-law declared it the best grilled cheese he'd ever eaten. The secret truly lies in the avocado, which transforms the sandwich from merely delicious to memorably amazing. The way the creamy avocado melds with the melted cheese creates a texture that's absolutely divine.

Perfect Cheese Selection

Not all cheeses are created equal when it comes to grilled cheese sandwiches. For this recipe, choose cheeses with excellent melting properties. Sharp cheddar provides classic flavor, while gruyere adds nutty sophistication. For maximum meltiness, consider Monterey Jack or American. The beauty of this recipe is that you can mix two different cheeses for more complex flavor profiles, like combining sharp cheddar with creamy Havarti.

Avocado Tips

Choosing the perfect avocado makes all the difference in this recipe. Look for California avocados that yield slightly to gentle pressure but aren't mushy. They should feel heavy for their size. To ripen firm avocados quickly, place them in a paper bag with a banana or apple overnight. Once cut, brush exposed avocado with a tiny bit of lemon juice to prevent browning if you're preparing multiple sandwiches.

Make It A Meal

Transform this sandwich into a complete meal by serving it alongside homemade tomato soup for the ultimate comfort food pairing. The acidity of the tomato soup perfectly balances the richness of the sandwich. For a lighter option, serve with a simple green salad dressed with vinaigrette. The bright, crisp salad provides textural contrast to the warm, gooey sandwich. Cold milk is the classic beverage pairing, but a crisp apple cider or light beer works wonderfully for adults.

Ingredients

→ Grilled Cheese Sandwich

01 2 slices seeded whole grain bread, or bread of choice
02 2 slices (1 oz each) cheese, such as cheddar, cheddar jack, or gruyere
03 1/4 ripe Fresh California Avocado, seeded, peeled, and sliced
04 2 slices crispy cooked bacon, cut or folded horizontally in half
05 1/2 Tbsp butter, melted
06 1/2 Tbsp mayonnaise

Instructions

Step 01

Preheat an individual sandwich maker. Place one slice of cheese on one slice of bread.

Step 02

Spread avocado slices over the cheese slice leaving a border. Add the second slice of cheese, bacon slices, and the other bread slice on top.

Step 03

Combine melted butter and mayonnaise. Spread half the mixture on the top slice of bread.

Step 04

Place the sandwich into the sandwich maker with the butter-mayo side down. Spread the remaining mixture on the other side of the sandwich, close the maker, and cook for 2 to 5 minutes or until golden brown and cheese is melted.

Step 05

Using a heat-resistant spatula or tongs, remove the sandwich. Cut in half and serve immediately.

Step 06

Preheat skillet over medium-high heat. Place the sandwich in the skillet and spread butter-mayo mixture on the second side of bread. Cook for 3 minutes, flip carefully, and press gently with a spatula or grill press. Cook for 2 minutes or until golden brown. Add extra butter if bread feels dry, cooking briefly on both sides.

Notes

  1. Using melted butter and mayonnaise results in a crisp texture and buttery flavor.
  2. A large avocado, averaging 8 ounces, is recommended. Adjust quantities if using smaller or larger avocados.
  3. Using two different types of cheese, such as Swiss and mozzarella, can elevate the flavors.
