Avocado BLT Grilled Cheese

Featured in: Warm Breakfast Recipes

This elevated grilled cheese combines the beloved BLT flavors with creamy avocado and melted cheese for a satisfying meal. Start by crisping thick-cut bacon until golden, then layer it with ripe avocado slices, fresh tomato, and romaine lettuce between cheese-topped bread slices. Butter the outside generously and griddle until the cheese melts and the bread turns golden brown, about 3-4 minutes per side. The result is a warm, crispy-on-the-outside sandwich with perfectly melted cheese and fresh, cool layers inside.

The smell of butter hitting a hot skillet always makes me pause, even on the busiest mornings. I was experimenting one afternoon, trying to use up avocado before it turned, and realized my usual grilled cheese felt lonely next to leftover bacon cooling on the counter. What started as cleanup became something I now crave on repeat: creamy, crunchy, salty, and just indulgent enough to feel like a treat. Every bite is proof that the best recipes come from happy accidents.

I made this for my sister once after she had a long day, and she barely spoke until she finished the whole thing. She looked up, smiled, and just said more. That's when I knew this wasn't just another sandwich. It's become my go to whenever someone needs comfort that tastes like a hug but feels a little fancy.

Ingredients

  • Sourdough or country white bread: A sturdy bread is essential here because it holds up to all the fillings without getting soggy, and sourdough adds a subtle tang that balances the richness.
  • Unsalted butter, softened: Softened butter spreads evenly and creates that beautiful golden crust without tearing the bread.
  • Cheddar or Monterey Jack cheese: Cheddar brings sharpness, Monterey Jack melts like a dream, and either one glues everything together with creamy, gooey magic.
  • Thick cut bacon: Thick slices stay crispy and meaty, giving you that satisfying crunch in every bite instead of disappearing into the sandwich.
  • Ripe avocado: Creamy avocado adds richness and a buttery texture that makes this sandwich feel luxurious.
  • Medium tomato: Fresh tomato brings bright acidity and juiciness that cuts through all the richness.
  • Romaine or butter lettuce: Crisp lettuce adds a refreshing crunch and a little bit of lightness to balance the decadence.
  • Salt and freshly ground black pepper: A little seasoning on the avocado and tomato wakes up their flavors and ties everything together.

Instructions

Crisp the bacon:
Cook the bacon in a skillet over medium heat until it is deeply golden and crispy, then drain on paper towels. This step fills your kitchen with the kind of smell that makes everyone wander in asking when lunch is ready.
Butter the bread:
Lightly butter one side of each bread slice with softened butter, making sure to reach the edges. This is what creates that irresistible golden crust.
Build the sandwiches:
Place two bread slices buttered side down, then layer each with cheese, bacon, lettuce, tomato, and avocado, seasoning the avocado and tomato with salt and pepper. Top with another slice of cheese and the remaining bread, buttered side up.
Grill to perfection:
Heat a large nonstick skillet or griddle over medium low heat, place the sandwiches in, and cook until golden brown and the cheese is melted, about 3 to 4 minutes per side, pressing gently with a spatula. The gentle press helps everything meld together without squishing out the fillings.
Rest and serve:
Remove from the skillet, let cool for 1 to 2 minutes so you do not burn your mouth, slice in half, and serve immediately. That brief rest also helps the cheese set just enough to hold its shape when you bite in.

There is something about cutting this sandwich in half and watching a little bit of avocado peek out, the cheese still stretching between the two halves. It is one of those small, perfect kitchen moments that makes you remember why you love to cook. I have served this to friends, to myself on quiet Saturdays, and every time it feels like a little celebration.

Making It Your Own

I have tried this with pesto smeared on the inside, and it added an herby brightness that made the whole sandwich sing. A swipe of mayonnaise works too if you want extra creaminess, and I have even used turkey bacon when I wanted something a little lighter. The beauty of this recipe is that it welcomes your tweaks without losing its soul.

Choosing Your Bread

Sourdough is my favorite because the slight tang plays so well with creamy avocado and salty bacon, but a sturdy country white or even a good whole grain works beautifully. Just avoid anything too soft or it will turn soggy under the weight of all those fillings. Thicker slices hold up better and give you more surface area for that buttery, golden crust.

Serving and Storing

This sandwich is absolutely best served fresh and hot, right off the griddle when the cheese is still molten and the bread is crackling crisp. If you must make it ahead, wrap it loosely in foil and reheat in a low oven, but know it will never quite recapture that just made magic.

  • Serve with a handful of kettle chips or a simple green salad to round out the meal.
  • If you have leftover components, store them separately and assemble fresh sandwiches as needed.
  • Leftover cooked bacon keeps in the fridge for up to a week and makes breakfast or snacking dangerously easy.

This sandwich has earned a permanent spot in my kitchen rotation, and I think it will in yours too. Make it once, and you will understand why sometimes the simplest upgrades create the most craveable meals.

Recipe Questions & Answers

What type of bread works best for this sandwich?

Sourdough or country white bread are ideal choices. Their sturdy texture withstands the heat and butter without falling apart, while providing a delightful contrast to the creamy avocado and melted cheese. Brioche or challah also work well for a richer taste.

How do I prevent the avocado from browning?

Assemble the sandwich right before grilling and add the avocado slices just before cooking. Choose a perfectly ripe but firm avocado, and consider a light squeeze of fresh lemon juice on the slices to prevent oxidation if making ahead.

Can I make this vegetarian?

Absolutely. Skip the bacon or replace it with crispy tempeh strips, smoked mushrooms, or plant-based bacon. The sandwich remains delicious and satisfying with the combination of creamy avocado, fresh vegetables, and melted cheese.

What temperature should I use to cook the sandwich?

Medium-low heat is essential to prevent burning the bread while allowing the cheese to melt completely. This gentle approach ensures even melting and a golden-brown exterior without a blackened crust.

How long does this take from start to finish?

Total preparation and cooking time is about 20 minutes. Bacon takes roughly 5-7 minutes, assembly takes 3-5 minutes, and grilling takes about 6-8 minutes for both sides. This makes it perfect for quick weeknight meals.

Should I cut the sandwich before serving?

Yes, slice diagonally in half after a brief 1-2 minute cooling period. This allows the cheese to set slightly while remaining warm and prevents the filling from spilling out, making it easier to enjoy.
