Whole30 Salmon Croquettes

Salmon croquettes are a classic Southern weeknight favorite and a perfect pantry meal when you want something quick, satisfying, and family-friendly. This Whole30 version keeps the familiar comfort of the original while swapping out non-compliant binders so you can enjoy a crisp, golden croquette without the breadcrumbs. These croquettes are easy to make, full of flavor, and ideal for serving as an appetizer, main course, or protein-packed snack.

My mom used to make these with canned salmon and crumbled crackers for the coating, but this Whole30-friendly recipe swaps the traditional crumb for tapioca starch to keep the croquettes tender on the inside and crisp on the outside. The result is a nostalgic, family-approved dish that’s also compliant with Whole30 guidelines.

Why you’ll love these Whole30 Salmon Croquettes

They’re fast to prepare, require minimal ingredients you likely already have on hand, and deliver a comforting, crispy bite with bright seasoning. Croquettes are versatile—serve them with a Whole30-compliant tartar-style sauce, a squeeze of lemon, or alongside a fresh salad or roasted vegetables for a quick weeknight meal.

Ingredients

2 cans (6-ounce) salmon, drained
2 cloves garlic, minced
1/4 cup white or yellow onion, very finely diced
2 tablespoons mayonnaise (Whole30-compliant)
1 teaspoon grainy mustard
1 teaspoon Louisiana-style hot sauce (optional)
1 teaspoon Old Bay seasoning
1 large egg
1/4 teaspoon black pepper
1/4 teaspoon kosher salt
2 teaspoons tapioca starch (for binding and crisping)
3 tablespoons avocado oil (for frying)

Step-by-step Instructions

Step One — Make the croquette mixture

In a large bowl, flake the drained canned salmon with a fork and combine with the minced garlic, finely diced onion, mayonnaise, grainy mustard, hot sauce (if using), Old Bay, egg, black pepper, kosher salt, and tapioca starch. Mix gently but thoroughly until the ingredients are evenly distributed. The mixture should hold together when pressed; if it seems too wet, add a touch more tapioca starch.

Step Two — Shape the croquettes

Using clean hands, scoop approximately 2 tablespoons of the mixture and form each portion into an oval croquette—similar in shape to a small egg. Place formed croquettes on a clean plate or baking sheet while you shape the rest. This recipe makes several small croquettes perfect for serving as appetizers or as part of a main meal.

Step Three — Fry until golden

Heat the avocado oil in a skillet over medium heat until shimmering but not smoking. Carefully lay the croquettes in a single layer and cook 2–3 minutes per side, or until a deep golden crust forms. Work in batches if necessary so the pan isn’t crowded; overcrowding lowers the oil temperature and prevents a crisp exterior.

Step Four — Drain and serve

Transfer cooked croquettes to a plate lined with paper towels to absorb excess oil. Serve warm with a Whole30-compliant tartar-style sauce, a wedge of lemon, or your favorite compliant condiment. These are delicious as an appetizer, on a salad, or paired with roasted vegetables for a complete meal.

Tips and variations

Substitute cooked flaked salmon for canned salmon if you prefer; leftover baked or grilled salmon works well.
If you want a breaded exterior, dip each croquette lightly in additional tapioca starch before frying for extra crunch while keeping the recipe Whole30-compliant.
For a milder flavor, omit the hot sauce and add a little extra mustard or lemon zest.
To bake instead of fry, arrange croquettes on a parchment-lined sheet, brush lightly with oil, and bake at 400°F (200°C) until golden, flipping once.

Recipe FAQs

Can I use anything other than tapioca starch?

Tapioca starch helps keep these croquettes Whole30-compliant and gives a light crisp. If you’re not following Whole30, you can substitute all-purpose flour or cornstarch, though results will vary slightly.

Can I use a salmon fillet instead of canned salmon?

Yes. A cooked, flaked salmon fillet works nicely—use leftovers or quickly poach or bake a small fillet before flaking with a fork.

Notes and serving suggestions

I love serving these cleaned-up Southern salmon croquettes with a Whole30-style tartar sauce to add tang and richness. If you’re in a hurry, a compliant ketchup or a squeeze of fresh lemon also complements the flavor beautifully. Leftovers keep well in the refrigerator for 2–3 days and reheat gently in a skillet to restore crispness.
