There’s something incredibly satisfying about a plate of crispy fried smelt. These tiny, delicate fish are light, fresh, and flavorful — and when fried until golden, they have that irresistible crunch that makes you keep reaching for just one more. Paired with a simple lemon-caper aioli, this is the kind of dish I love to make when I want a no-fuss, crowd-pleasing seafood snack or an easy starter before dinner.
I grew up around small fried fish like this, and it always reminds me of simple, relaxed meals — nothing fancy, just good food you can eat with your fingers and a wedge of lemon on the side. If you’ve never cooked smelt before, this recipe is a great way to get comfortable with it.
Why You’ll Love This Crispy Fried Smelt
What makes this recipe shine is its simplicity. Smelt is naturally mild in flavor, which means it takes on seasoning beautifully. When coated in flour and fried, the outside turns crisp and golden while the inside stays soft and flaky.
You can make this recipe two ways — pan-fried for maximum flavor or air-fried for a lighter, less hands-on approach. Either way, the results are delicious. I also love that this dish comes together quickly, so it’s perfect for weeknights or casual get-togethers.
Ingredient Insights and Helpful Tips
-
Smelt: These small fish usually come frozen and already cleaned. If not, you can ask the fishmonger to clean them or do it yourself. If you can’t find smelt, fresh anchovies work as a substitute (but not tinned ones).
-
Flour: A light dredge is enough. Too much flour can make the coating soggy.
-
Oil: Olive oil gives a beautiful flavor when pan-frying, but for air frying, a neutral spray oil works better.
-
Lemon: Fresh lemon juice over hot fish adds brightness and makes everything taste more alive.
-
Mayonnaise: A good-quality mayo is the base for the quick aioli.
-
Capers, Dijon Mustard, Garlic, Lemon Zest and Juice: These ingredients bring sharpness, tang, and a little punch to the dipping sauce.
Tips and Tricks
After making this several times, a few tricks really make a difference:
-
Always pat the smelt dry before dredging in flour. Moisture makes the coating uneven.
-
Dredge them right before frying so the coating stays light and crisp.
-
Don’t crowd the pan or air fryer basket. It’s better to work in batches to get even browning.
-
A quick squeeze of lemon right before serving lifts the flavor in the best way.
Make Ahead Tips
You can clean and prep the smelt in advance to save time.
-
If you buy whole smelt, gut and clean them earlier in the day and store them in the fridge on a paper towel-lined tray.
-
You can also make the lemon-caper aioli ahead of time and keep it chilled. The flavors actually deepen and mellow out after a few hours.
-
When ready to cook, just dredge and fry fresh — that’s the key to keeping them crisp.
Serving Suggestions
Crispy fried smelt is the kind of dish that doesn’t need much to shine. I usually serve it on a big platter with lemon wedges and the dipping sauce in the center. But you can also turn it into a more complete meal by pairing it with:
-
A crisp side salad
-
Roasted or boiled potatoes
-
Light pasta with olive oil and herbs
-
Warm crusty bread to mop up the aioli
This dish works beautifully as an appetizer or even as part of a casual seafood dinner.
Storage
If you happen to have leftovers (which doesn’t happen often in my kitchen), let them cool completely before storing. Place them in an airtight container and refrigerate for up to 2 days. Reheat them in the oven or air fryer to bring back the crispiness. Avoid microwaving — it tends to make the coating soft and soggy.
FAQs
Do I need to clean smelt before cooking?
Yes, the innards can make the fish bitter, so they need to be removed. Many stores sell them pre-cleaned, but if not, it’s a quick job with kitchen scissors.
Can I use anchovies instead of smelt?
Yes, fresh anchovies can be used, but not tinned. Tinned anchovies won’t give the same result.
Which method is better — pan-frying or air frying?
Pan-frying gives the best flavor and crispness, but air frying is cleaner, less oily, and still tasty.
Can I make the aioli from scratch?
You can, but using mayonnaise as a base is quick and easy. The flavor comes from the lemon, capers, mustard, and garlic.
