Gluten-Free Avocado BLT
I don’t know about you, but I love a good sandwich, and I firmly believe a BLT is one of the great classics. Crisp bacon, juicy tomato and cool, crunchy lettuce on toasted bread is simple perfection. Today, however, I am sharing my favorite way to make it even better: with ripe, creamy avocado tucked between the layers and hearty gluten-free multigrain bread that toasts up beautifully. If you love my Perfect Bagel Sandwich, this one will feel right at home on your table.
Moreover, this is a sandwich that works for just about anyone at the table. The multigrain gluten-free bread I reach for has a nutty crust, a soft interior and lovely texture from flax, sunflower and pumpkin seeds, so nobody feels like they are missing out. Equally important, it comes together in under thirty minutes, which makes it as easy for a weekday lunch as it is for a casual weekend brunch alongside my Open Face Breakfast Bruschetta Sandwich.
In essence, this is comfort food with a fresh, elevated twist. Pair it with my Bacon, Spinach & Cheese Egg Muffins for a brunch spread, or keep it simple with a bowl of fruit. Enjoy!
What Is a Gluten-Free Avocado BLT?
A BLT is a sandwich of bacon, lettuce and tomato on toasted bread with a swipe of mayonnaise. This version adds sliced avocado for creaminess and uses gluten-free multigrain sandwich bread, toasted on one side so it stays crisp outside and soft inside.
Furthermore, oven-baking the bacon means every slice cooks evenly, lies flat and stays perfectly crisp, which makes the sandwich easier to stack and much neater to eat.
Gluten-Free Avocado BLT Ingredients (With Purpose & Flavor Notes)
Thick-Cut Bacon
Thick-cut bacon holds its crunch and gives the sandwich real substance. Baking it on parchment keeps it flat and evenly crisp.
Gluten-Free Multigrain Bread
Choose a sturdy gluten-free multigrain sandwich bread. Toasting one side gives you structure and a golden crunch.
Ripe Avocado
Avocado adds a buttery, creamy layer that makes this BLT feel indulgent. It should yield gently when pressed. Slice it just before assembling so it stays bright green.
Large Tomato
A ripe, juicy tomato brings sweetness and acidity to balance the rich bacon and avocado.
Romaine Lettuce
Crisp romaine leaves add fresh crunch and hold up better than softer lettuces.
Mayonnaise
A generous layer of mayo on the untoasted side of the bread keeps every bite moist and ties the flavors together.

Everything I Love for this recipe
Large Nonstick or Cast-Iron Skillet (12-inch)
A versatile, everyday essential that does the heavy lifting in this recipe. The wide surface allows you to toast bread, cook bacon, scramble eggs, and assemble the sandwiches without crowding—ensuring even cooking and beautiful browning, all on the stovetop.
Mixing Bowl
Simple but essential, a medium mixing bowl gives you the space to whisk eggs smoothly and evenly. It helps create a consistent texture, ensuring soft, creamy eggs every time.
Whisk
A whisk introduces air into the eggs, resulting in a lighter, fluffier scramble. It’s a small tool that makes a noticeable difference in texture—perfect for recipes where simplicity meets intention.
Bread Knife
Sourdough has a crust that crushes under a chef’s knife. Cut thick slices, because thin ones collapse under this many toppings.
Chef’s Knife
Thin red onion and clean avocado slices both depend on a sharp blade.
Bamboo Cutting Boards
Bacon, onion and avocado each get their own board, so nothing raw touches what is ready to serve.
Handheld Mandoline
Red onion has to be paper thin here or it takes over the bite, and this is the easiest way to keep it consistent.
Silicone Spatula Set
Soft scrambled eggs are folded, not stirred. A flexible spatula keeps the curds big and tender.
Pepper Grinder
Freshly cracked pepper over the eggs is the finishing touch that makes this taste like brunch out.
Serving Platters
Three sizes, so you can run the classic version and the smoked salmon version side by side.
Everything Bagel Seasoning
A shake over the avocado and the egg does what three separate ingredients would.
Flaky Sea Salt
Last thing on the plate. Flakes stay on top of soft eggs and avocado instead of dissolving in.
How To Make a Gluten-Free Avocado BLT

Shelf Life & Storage Tips
Best Fresh
A BLT is best eaten right after assembling, while the toast is crisp and the avocado is bright.
Storing Bacon
Refrigerate leftover cooked bacon in an airtight container for up to 4 days. Rewarm on a sheet pan at 350°F for 3 to 5 minutes.
Keeping Avocado Fresh
Store a cut avocado half with the pit in, brushed with lemon juice and wrapped tightly, for up to 1 day.
Make Ahead
Bake the bacon and slice the tomato and lettuce up to a day ahead, then toast and assemble just before serving.
Frequently Asked Questions
Why bake bacon instead of frying it?
Baking cooks every slice evenly and flat with less splatter, which makes the sandwich easier to stack.
Do I need to toast the bread?
Yes. Gluten-free bread is much sturdier and tastier toasted, and toasting one side keeps the inside soft.
How do I keep the avocado from browning?
Slice it just before assembling, or squeeze a little lemon juice over the slices.
Can I make this ahead for a party?
Prep the components ahead, but assemble within an hour of serving so the bread stays crisp.
How many sandwiches does this make?
This recipe makes 2 sandwiches and doubles easily.
Final Thoughts
A great BLT is proof that the simplest recipes are often the most satisfying. With this in mind, I hope this avocado version becomes one of your go-to lunches, whether you are cooking for yourself or for a table full of friends.
All things considered, it is fresh, easy and welcoming for everyone, which is exactly how I like to host. If you make it, I would love to hear how you served it.
