This decadent grilled cheese combines the beloved BLT flavors with gooey melted cheddar or Monterey Jack cheese.

My neighbor showed up one Saturday morning with a bag of avocados from her tree and a craving for something indulgent. We stood in my kitchen, staring at the bacon I'd just bought and the block of cheddar in the fridge, and somehow this sandwich was born. It wasn't planned, wasn't fancy, just two people layering whatever sounded good between buttered bread. The smell of that first batch browning in the skillet made us both go quiet, the kind of quiet that means you know you've stumbled onto something worth repeating.

I made this for my brother once after he'd spent all morning helping me move furniture. He doesn't say much when he eats, but halfway through the first half of his sandwich he looked up and asked if I had more bacon. That's when I knew it was a keeper. We sat on the porch with greasy fingers and didn't talk about anything important, just chewed and watched the afternoon light shift through the trees. Sometimes the best meals are the ones that don't need conversation.

Ingredients

  • Sourdough or country white bread: Pick a sturdy loaf that won't fall apart under all these layers, something with enough structure to hold up to the butter and heat without turning soggy.
  • Unsalted butter, softened: Soft butter spreads evenly and helps the bread turn that deep golden brown without burning, so leave it out on the counter while you prep everything else.
  • Cheddar or Monterey Jack cheese: Cheddar gives you sharp, tangy flavor while Monterey Jack melts like a dream, so use whichever you're craving or mix them both.
  • Thick-cut bacon: The thicker slices stay crispy even after they've been tucked into the sandwich, and they give you that satisfying chew you want in every bite.
  • Ripe avocado, sliced: Make sure it gives just a little when you press it, not mushy but soft enough to spread its creamy richness through every layer.
  • Medium tomato, sliced: A ripe tomato adds juicy sweetness and a pop of color, just pat the slices dry so they don't make your bread soggy.
  • Romaine or butter lettuce: Crisp lettuce keeps the sandwich from feeling too heavy and adds a fresh crunch that balances all that richness.
  • Salt and freshly ground black pepper: Don't skip seasoning the avocado and tomato, it wakes up their flavors and makes every bite taste intentional instead of flat.

Crisp the bacon:
Lay the bacon in a cold skillet and turn the heat to medium, letting the fat render slowly so the slices cook evenly and get crispy without burning. When they're deep golden and crunchy, move them to a plate lined with paper towels to drain.
Butter the bread:
Spread soft butter on one side of each slice, making sure to reach all the way to the edges so every bit of crust gets golden and crispy. This is the side that will touch the skillet, so don't be shy with it.
Build the sandwiches:
Place two slices buttered side down on your counter, then start layering: cheese first so it melts against the bread, then bacon, lettuce, tomato, and avocado, seasoning the tomato and avocado with salt and pepper as you go. Top with another slice of cheese and the remaining bread, buttered side facing up this time.
Grill low and slow:
Heat your skillet over medium-low and set the sandwiches in gently, pressing down just a little with your spatula to help everything meld together. Let them cook for three to four minutes per side until the bread is deep gold and the cheese has melted into all the cracks.
Rest and serve:
Pull the sandwiches off the heat and let them sit for a minute or two so the cheese sets just enough to not slide out when you cut. Slice in half and serve while the bread is still warm and crispy.

There was an afternoon last summer when I made four of these sandwiches for friends who dropped by unannounced. We ate them standing around the kitchen island, passing napkins and laughing about nothing in particular. One friend declared it the best grilled cheese she'd ever had, and I didn't argue. Sometimes a sandwich is just a sandwich, but sometimes it's the thing that makes people stay a little longer, talk a little easier, and leave a little happier.

Choosing Your Bread

Sourdough gives you that tangy flavor and sturdy chew, but if you want something softer and sweeter, country white works just as well. I've tried this on rye and whole wheat too, and while they both taste good, they can overpower the other flavors if they're too hearty. The key is finding bread that toasts up crispy on the outside but stays soft enough inside to bite through without everything sliding out the back.

Swapping Ingredients

If you don't eat pork, turkey bacon crisps up nicely and still gives you that salty crunch, though it won't have quite the same smoky depth. I've also made this with plant-based bacon for a friend, and while it's different, it still works as long as you season everything well. You can swap the cheddar for Swiss or provolone if that's what you have, just make sure it's a cheese that melts smoothly and doesn't turn grainy under heat.

Serving and Storing

This sandwich is best eaten right away while the bread is still crispy and the cheese is gooey, but if you have to save half for later, wrap it loosely in foil and reheat it in a skillet instead of the microwave. The microwave will turn the bread soft and sad, but a quick trip back to the pan brings some of that crunch back to life. Serve it with a handful of chips, a pickle, or a simple side salad, nothing fancy, just something to round out the plate.

  • Press gently with the spatula while grilling to help the layers stick without squashing all the fillings out the sides.
  • If the bread is browning too fast, lower the heat and cover the skillet with a lid for a minute to help the cheese melt through.
  • Use a serrated knife to cut the sandwich cleanly without smashing it flat and losing all that beautiful structure.

This sandwich has become my answer to lazy weekends, surprise guests, and days when I just want something that feels like a hug between two slices of bread. I hope it finds a spot in your kitchen the way it has in mine.

Recipe FAQs

What type of cheese works best?

Cheddar and Monterey Jack are excellent choices for their melting quality and mild flavor. You can also use muenster, provolone, or a combination for deeper complexity.

How do I prevent the avocado from browning?

Add the avocado slices just before griddling the sandwich. You can also lightly brush the cut sides with lemon or lime juice to slow oxidation.

Can I make this ahead of time?

Assemble and griddle just before serving for optimal crispness and melted cheese. The sandwich is best enjoyed fresh and warm.

What bread alternatives work well?

Sourdough and country white bread are traditional, but brioche, Texas toast, or focaccia add interesting variations in texture and flavor.

How do I achieve a perfectly melted cheese interior?

Use medium-low heat and cook for 3-4 minutes per side. Gently press with a spatula to ensure cheese contact with the hot bread and even melting throughout.

What condiments pair well with this sandwich?

Mayo, pesto, or aioli add extra flavor. A thin layer of whole grain mustard complements the bacon beautifully without overpowering the fresh ingredients.
