How to Make Salmon Burgers with Old Bay Mayonnaise, Caramelized Onions, and Avocado Recipe

Step 1: Prepare the Salmon Mixture

Start by pulsing the salmon in a food processor about 15 times until it’s broken down into small ⅛-inch pieces. Transfer most of these pieces to a large bowl, then pulse the remaining salmon until it forms a smooth paste after about 15 more pulses. This contrast between flaky chunks and paste keeps your patties tender but cohesive. Next, beat the egg and pulse it into the mixture to bind everything. Add the panko breadcrumbs, onion powder, garlic powder, Old Bay seasoning, mustard powder, fresh lemon juice, and freshly minced chives. Mix everything together until evenly combined. This mixture is where all magic happens—a beautiful blend of texture and flavor that will lead to truly outstanding salmon burgers.

Step 2: Form the Patties

Line a plate with parchment paper to prevent sticking, then divide the salmon mixture into four equal portions. Gently shape each into a round, thick patty that’s just the right size to fit your buns. Don’t compress them too tightly—the lightness will make them extra tender once cooked.

Step 3: Cook the Burgers

Heat the vegetable oil in a large skillet over medium heat. Place the salmon patties in the hot pan and let them cook undisturbed for about 3 minutes until you see a golden crust form underneath. Flip each patty carefully, then top them immediately with a slice of Havarti dill cheese. Continue cooking for another 3 minutes. The cheese will melt beautifully while the second side crisps up perfectly. Keep the heat steady to ensure burgers cook evenly without drying out.

Step 4: Make the Old Bay Mayonnaise

While the salmon burgers cook, mix together mayonnaise, minced chives, Old Bay seasoning, and fresh lemon juice in a small bowl until smooth and creamy. This Old Bay mayonnaise is the ultimate flavor booster—bright, tangy, and vibrantly spiced—perfect for spreading on your buns.

Step 5: Assemble the Burgers

Toast the brioche buns lightly for extra texture and warmth. Spread a generous layer of Old Bay mayonnaise on the cut sides of each bun. Place the salmon patties cheese-side up onto the bottom buns, then pile on sweet caramelized onions and creamy avocado slices. Top it all off with the bun lids, press down gently, and get ready for a sensational bite!

Garnishes

Add some fresh arugula or baby spinach leaves for a peppery crunch and color contrast. A squeeze of fresh lemon juice right before serving will elevate all those rich flavors, keeping everything bright and lively. You can also sprinkle a pinch of extra Old Bay for spice lovers who want an extra kick.

Side Dishes

These salmon burgers pair wonderfully with crispy sweet potato fries, a light cucumber salad, or grilled corn on the cob for some summer sunshine on your plate. For a healthier option, try a quinoa salad tossed with fresh herbs and lemon vinaigrette to complement the seafood flavors.

Creative Ways to Present

For a fun twist, serve these burgers open-faced with a drizzle of herb-infused olive oil and microgreens on top. Or try serving salmon burger sliders on mini brioche buns with toothpicks for parties or casual gatherings. These little presentation changes make your meal feel special and inviting every time.

Make Ahead and Storage

Storing Leftovers

Leftover cooked salmon patties can be stored in an airtight container in the refrigerator for up to 2 days. Keep the buns and toppings separate to avoid sogginess. This makes it easy to reassemble a fresh-tasting burger later.

Freezing

You can freeze the raw patties before cooking by placing them on a parchment-lined tray until firm, then transferring to a freezer-safe bag for up to 3 months. Thaw overnight in the fridge before cooking as directed.

Reheating

Reheat cooked patties gently in a skillet over medium-low heat or in a 350°F oven for about 8–10 minutes to retain moisture and crispness. Avoid microwaving to prevent rubbery texture. Assemble fresh with mayo, onions, and avocado after reheating for the best experience.

FAQs

Can I use canned salmon instead of fresh?

While fresh salmon offers the best texture and flavor, you can use high-quality canned salmon in a pinch. Just drain well and mash gently, adjusting the breadcrumbs to get the right consistency.

Is Old Bay seasoning essential for this recipe?

Old Bay brings a unique blend of spices that perfectly complements seafood. You could substitute a seafood seasoning blend, but you might miss out on that signature flavor punch.

How do I caramelize onions perfectly?

Cook sliced onions slowly in a little oil or butter over low heat for about 30–40 minutes until deeply browned and sweet. Stir occasionally to prevent burning—patience really pays off here!

Can I make this recipe gluten-free?

Absolutely! Just swap regular panko breadcrumbs for gluten-free breadcrumbs or crushed gluten-free crackers. Make sure your buns are gluten-free too.

What cheese works best besides Havarti dill?

You can experiment with other mild, melty cheeses such as Swiss, Monterey Jack, or mozzarella. Adding fresh herbs in the cheese, like dill or chives, enhances the flavor nicely.
