Make It Your Way

One of the best things about this Grilled Salmon BLT with Charred Scallion Mayo Recipe is how easy it is to tweak. I love to play around with the spice level or switch up the bread depending on what I have on hand, and it always turns out great.

Variation: I’ve sometimes swapped romaine for butter lettuce—it adds a softer crunch and a slightly sweeter flavor.
Dietary Modification: For a lighter version, use avocado mayo instead of traditional mayo—it gives a creamy texture with healthy fats.
Seasonal Twist: Try heirloom tomatoes in summer for extra color and incredible sweetness.
Grilling Method: Don’t have a grill? No worries, a grill pan or even broiling in your oven can bring you close to the smoky char flavor.

Step-by-Step: How I Make Grilled Salmon BLT with Charred Scallion Mayo Recipe

Grilled Salmon BLT with Charred Scallion Mayo Recipe - Recipe Step

Step 1: Get Your Bacon Perfectly Crispy

I usually cook my bacon first, either in a skillet or in the oven at 400°F for 15-20 minutes until it’s beautifully crispy. Bonus tip: I sometimes cook it the day before and keep it in the fridge so I’m not juggling too many steps at once.

Step 2: Prep and Season Your Salmon

Pat your salmon dry—that’s key for that nice crust when grilling. Mix up smoked paprika, oregano, garlic and onion powders, kosher salt, pepper, and red pepper flakes if you like a little heat. Then sprinkle that spice blend all over the salmon evenly.

Step 3: Heat the Grill and Cook the Salmon

Preheat your grill to somewhere between 400 to 450°F. Place the salmon flesh-side down and close the lid for about 6 to 8 minutes. You’re looking for the salmon to be opaque and opaque pink in the center. Don’t overcook—this fish deserves to stay juicy and tender!

Step 4: Grill Your Bread and Scallions

While the salmon chills for a few minutes, throw your sourdough bread and scallions on the grill. The bread only takes 1-2 minutes per side to get those signature grill marks. For the scallions, cook about 5 minutes total, turning once or twice until they’re slightly charred and soft.

Step 5: Make Charred Scallion Mayo

Slice the grilled scallions and mix them into the mayonnaise. This mayo takes on such a fantastic smoky depth from the scallions — it’s what transforms this BLT into something memorable.

Step 6: Assemble Your Sandwiches

If your salmon filet is large, cut it into portions that fit your bread slices. Spread about a tablespoon of the scallion mayo on each slice, then layer lettuce, salmon, tomato slices, crispy bacon, and top with the other bread slice. Slice in half and get ready to enjoy!

Pro Tips for Making Grilled Salmon BLT with Charred Scallion Mayo Recipe

Dry Your Salmon Thoroughly: I can’t stress this enough—patting the salmon dry helps get that beautiful sear and prevents sticking to the grill.
Don’t Overcook the Salmon: Keep a close eye during grilling; salmon continues cooking after you remove it, so pulling it off a bit early keeps it juicy.
Make the Mayo Ahead: I like to prepare the charred scallion mayo while the salmon is resting, so everything comes together quickly.
Use Grill Marks as Your Guide: Grilling bread and scallions just right adds texture and smoky flavor without making them soggy or burnt.

How to Serve Grilled Salmon BLT with Charred Scallion Mayo Recipe

Grilled Salmon BLT with Charred Scallion Mayo Recipe - Serving Suggestion

Garnishes

I’m a big fan of keeping it simple here. A few fresh basil or dill leaves sprinkled on top add a nice herbal brightness. If you want a little extra kick, a light drizzle of lemon juice or a scattering of capers bring vibrant contrast.

Side Dishes

For sides, crisp sweet potato fries or a simple green salad with a light vinaigrette are my favorite go-tos. Sometimes I whip up a lemony quinoa salad to keep things fresh and nutritious without overpowering that smoky salmon flavor.

Creative Ways to Present

I once made these sandwiches for a brunch gathering and served them open-faced on a wooden board with a few colorful heirloom tomato slices scattered around. It’s such a crowd-pleaser and looks effortlessly elegant!

Make Ahead and Storage

Storing Leftovers

If you have leftovers, wrap the sandwich tightly in foil or plastic wrap and store it in the fridge within two hours. This keeps the flavors fresh without the bread getting too soggy. I usually keep the mayo and salmon separate if I plan to store for more than a day.

Freezing

Freezing a fully assembled salmon BLT isn’t my favorite because the bread can lose its texture, but you can freeze cooked salmon and charred scallion mayo separately. Just thaw in the fridge overnight, then assemble fresh to keep that perfect bite.

Reheating

For reheating, gently warm the salmon in a low oven or microwave until just heated through. Toast up the bread again separately to bring back that grill-charred crunch. Reassemble with fresh mayo and toppings for the best taste.

FAQs

Can I make the Grilled Salmon BLT with Charred Scallion Mayo Recipe without a grill?

Absolutely! You can use a grill pan on your stovetop or broil the salmon in your oven for similar results. For the scallions, roasting under the broiler until charred works great too. Just keep a close eye to avoid burning.
What’s the best type of salmon to use?

Fresh wild-caught salmon is ideal because of its firm texture and rich flavor. If fresh isn’t available, high-quality frozen salmon works well too—just thaw completely and pat dry before seasoning.
Can I prepare the charred scallion mayo ahead of time?

Yes! In fact, prepping it ahead allows the flavors to meld nicely. Store in an airtight container in the fridge for up to 2 days. Just give it a quick stir before spreading.
How do I prevent my sandwich from getting soggy?

To keep everything crisp, avoid overloading with wet tomatoes and don’t spread mayo directly on the bread if you’re packing it ahead. Layer lettuce or a barrier ingredient between moist components and the bread to maintain crunch.

This Grilled Salmon BLT with Charred Scallion Mayo Recipe is one of those meals I turn to when I want something both comforting and elevated.
