This fully loaded Avocado BLT Sandwich with crispy oven-baked bacon, ripe garden tomatoes, cheddar cheese, and cucumber slices is a Wisconsin-style sandwich night the whole family loves! Go way beyond the bacon, lettuce and tomato with extra veggies and a slice of cheese for a seriously hearty sandwich night! A classic summer dinner and the best use for garden tomatoes at their peak!

Loaded Avocado BLT Sandwiches with Cheese are one of my favorite sandwiches, and a great way to use garden tomatoes and add extra veggies. Back home in Wisconsin, they always come with cheese!
I was working at the Hilton Hotel in Minnesota years back and got an order for a BLT. I made it and sent it out. A few minutes later the server comes back to me and says "I didn't order cheese on this." So I say to him, "Um, you didn't say no cheese."
We go back and forth awhile until I realize "Toto, I don't think we're in Wisconsin anymore." It never dawned on me not to put cheese on it! And that's how you'll get it if you're eating at our house.
These BLT's are loaded with cheese and avocado, which adds a delicious healthy creaminess. We wait until we have those ripe and juicy tomatoes from the garden, cucumbers too!

Ingredients
I've always thought that the classic Bacon, Lettuce and Tomato was never enough! Avocado and cheese make great additions, while cucumbers can be added for a crisp freshness and extra nutrition. We like our BLT's fully loaded, the more additions, the better!
- Bacon - Try cooking your bacon on a sheet pan in the oven instead of a frying pan, game changer! You can also buy bacon when it's on sale and freeze it raw so you can make BLT's any time. You can also freeze extra cooked bacon.
- Lettuce - Use any type of lettuce or salad greens you like!
- Tomato - The big juicy slicer tomatoes from the garden or the farmer's market are what BLT's are all about! Wait for those perfectly ripe summer tomatoes.
- Bread - You can use any kind of bread you like and choose to toast it or not. Homemade Dutch Oven Bread for BLT's is amazing!
- Avocado - Avocado makes BLT's into a seriously substantial sandwich! Make sure your avocado is ripe and add as much or as little as you like.
- Cheese - To me, the best cheese for BLT's is sliced cheddar or white cheddar. You could also use Muenster, Provolone or really any cheese you like. I would not use American, not my favorite and it's best when melted.
- Cucumber - Add extra nutrition and a bit of extra freshness with sliced cucumbers. Red onion slices are also a great veggie addition.
- Mayonnaise - A personal preference, I love just the basic mayo on BLT's.

Instructions
Step 1 - Cook the Bacon in the Oven. I always cook bacon on a sheet tray in the oven at 400° convection bake for about 20 minutes. This method is less messy and more efficient than cooking it in a frying pan.
You can usually fit the whole package of bacon on a large sheet pan. It cooks evenly and without any work from you.
Check on it after 15 minutes and flip it with tongs. Ovens can have hot spots, so some strips may be done a few minutes before the rest.
I like to remove pieces to a plate as they are done without a paper towel, a little extra bacon grease is not a bad thing!

Step 2 - Prepare your other ingredients. Make sure your avocado is ripe, with black skin not green, and soft when pressed. To ripen an avocado, leave it on the counter instead of in the fridge for a day or two.
Cut your avocados in half lengthwise around the pit and twist open. Hit the pit gently with your knife (be careful). When the knife is stuck in the pit, twist to remove it and discard.
Make slices the long way in the avocado flesh with a knife and scoop out with a spoon onto the sandwiches.

Step 3 - Assemble the BLT's. Decide whether to toast your bread, and pile it with sliced avocado, lettuce, tomato, bacon, cucumber, cheese and spread with mayo. Slice is half and serve.

Recipe Tips
- Cook Bacon in the Oven - This is how I always cook bacon! You can cook more at a time than in a frying pan, it's less messy and cooks evenly without your constant attention.
- The rendered bacon fat on the sheet pan can even be strained into a jar and kept in the fridge. I use it to fry eggs!
- Ripe Avocado - Make sure your avocado is ripe or it is nearly impossible to eat! It should have black skin and be soft when pressed. I like to buy a lot of green unripe avocados at a time, keep them all in the fridge, and just put one out to ripen on the counter for a day or two as needed.
- Don't Refrigerate Tomatoes - Leave tomatoes on the counter with your onions, potatoes and bananas! They will have the best texture and flavor when stored at room temperature.
- Storage - Leftover Loaded Avocado BLT's can be stored in an airtight container in the fridge and eaten the next day. If you store the ingredients separately, they will last a couple days. You can give the bacon a quick microwave to warm it.
- Freezer Tips - Leftover cooked bacon can also be chopped and frozen. This is why I always cook the whole package. Frozen cooked bacon is great for throwing in omelets, or using on Loaded Baked Potatoes or in Potato Corn Chowder. You can also freeze whole packages of raw bacon so sandwich night is always on hand!

What to Serve with BLT's
Avocado BLT's make a great dinner with a few simple side dishes ideas.
- Soup and Sandwich Night - Make it a soup and sandwich night with Creamy Asparagus Soup, Zucchini Corn Chowder, or Roasted Tomato Basil Soup.
- Summer Salad - Round out the meal with fresh hearty salads like this Green Bean Salad, Tomato Feta White Bean Salad, and Broccoli Salad
- A Quick Side Dish - Add Charred Corn on the Cob, Parmesan Kale Chips, or Green Beans and Carrots with Butter!
- Chips and Salsa - Serve it simply with chips and Peach Corn Salsa or Mango Corn Salsa!
Recipe FAQs
Keep your tomatoes in the middle of a BLT to keep it from getting soggy. Spread mayo on the bread and top with sliced avocado, lettuce, tomato, bacon, cucumbers, and a slice of cheese!
A BLAT is simply a BLT with avocado added, Bacon, Lettuce, Avocado, and Tomato. The name has become popular as avocado BLTs have become mainstream. This recipe is essentially a BLAT with a few extras like cheddar cheese, cucumber, and whatever fresh garden vegetables are ready to pick. Call it a BLAT, call it a loaded BLT, either way it's the same delicious sandwich!
Cheddar or white cheddar cheese is the best cheese for a BLT. Use good quality cheese for the best flavor. You can also use provolone, Muenster, havarti, or gouda but avoid American cheese.
Whether to toast the bread for a BLT is a personal preference. However, BLT's are usually served toasted. You can toast your bread in the toaster or add it to the oven as your bacon finishes cooking.
For a BLT, you want bread sturdy enough to hold up to the juicy tomatoes and creamy avocado without getting soggy. Classic white sandwich bread toasted until golden is the traditional choice and still one of the best. Sourdough is a great upgrade, more sturdy and with stronger flavor. A bakery-style white or Italian or French loaf also works well.

- 8 slices bread can be toasted
- 1 to 2 avocado sliced
- lettuce
- 1 to 2 tomato sliced
- 4 slices cheddar or white cheddar cheese
- 1 cucumber sliced (optional)
- mayonnaise (optional)
Instructions
- Preheat the oven to 400° convection bake and lay bacon strips on a large sheet. You may be able to fit the whole package if you lay them tight together. Cook until crisp, about 20 minutes, but check it often and flip bacon if needed. Drain on a plate as each piece is done.

Notes
- Make sure your avocado is ripe with black skin and soft flesh when the skin is pressed. To ripen, keep an avocado on the counter for a day or two.
- Cheddar or White Cheddar are my favorite but you can use Provolone, Muenster, or any cheese you like.
- Extra cooked bacon can be chopped and frozen and used in omelets, breakfast tacos, loaded baked potatoes, or pasta dishes with veggies and cream.
