Ingredients You’ll Need to Gather

1 lb Fresh white fish fillets (such as cod, tilapia, or haddock) — Mild, flaky fish that holds together well when pan-seared.
1/4 cup All-purpose flour — Light coating for a delicate crust and help for even browning.
1/2 teaspoon Salt — Enhances the natural flavor of the fish.
1/4 teaspoon Black pepper — A gentle peppery note.
1/2 teaspoon Paprika — Adds color and a soft smoky warmth.
1/4 cup Unsalted butter — The star for the buttery pan sauce and golden sear.
2 tablespoons Fresh lemon juice — Bright acidity to balance the butter.
1 unit Lemon zest, for garnish — Fragrant citrus oils that make the dish sing.
Fresh parsley — A green, herby finish that freshens every bite.
1/2 cup Mayonnaise — The base of the garlic aioli for creaminess.
2 cloves Garlic cloves, minced — Punchy, aromatic flavor in the aioli.
1 tablespoon Fresh lemon juice, to taste — Brightens the aioli and ties it to the fish.
Salt and pepper — To season the aioli and adjust to your taste.

A quick note: if you are feeling decadent, swap the mayonnaise for half mayo and half Greek yogurt for a tangier aioli. If you want ideas for seafood with a lemon-butter profile, try my favorite baked salmon with lemon butter sauce for another easy weeknight option.

Let’s Get Cooking: Step-by-Step

Here are clear, numbered steps to bring everything together. Take your time and savor the little wins along the way.

Pat the fish fillets dry with paper towels and cut them into bite-sized pieces, about 1 to 1.5 inches. Drying helps the flour adhere and encourages browning.
In a shallow bowl, combine the all-purpose flour, salt, black pepper, and paprika. Toss the fish pieces in the seasoned flour until lightly coated, shaking off any excess.
Heat a large skillet over medium heat and add the unsalted butter. Once the butter foams and begins to turn a light golden color, add the fish bites in a single layer, leaving space between pieces so they brown rather than steam.
Cook the fish for 2 to 3 minutes per side, depending on thickness, until each piece is golden and flakes easily when tested with a fork. Work in batches if necessary to avoid crowding the pan.
Remove the cooked fish to a warm plate. Add the fresh lemon juice to the pan and swirl to pick up the brown bits, creating a quick lemon-butter sauce. Spoon this over the fish and sprinkle with lemon zest and chopped fresh parsley.
For the garlic aioli, whisk together the mayonnaise, minced garlic, and 1 tablespoon fresh lemon juice in a small bowl. Season with salt and pepper to taste. Let the aioli sit for at least 10 minutes so the garlic mellows and the flavors meld.
Serve the fish bites hot with the garlic aioli on the side for dipping, and enjoy immediately.

If you want a shortcut for a garlicky buttery approach to meat dishes while the fish cooks, I sometimes cook a quick pan of garlic butter steak bites with a rich parmesan cream sauce for guests who crave a heartier option.

My Go-To Tricks for Perfect Bites

Use room temperature fish so it cooks evenly and doesn’t seize up in the pan.
Make sure the butter is hot enough before adding the fish; a shimmering surface signals the right temperature.
Don’t overflip. Let each side form a golden crust before turning to preserve texture.
Let the aioli rest while the fish cooks. Garlic mellows and the flavors become more rounded.
If your fish is very wet, dust with a bit more flour just before cooking to help it brown better. For a quick inspiration, I sometimes adapt techniques from garlic butter air fryer steak bites when I want an alternative cooking method.

Creative Twists You Can Try

Add a pinch of cayenne to the flour mix for a subtle heat that plays nicely with lemon.
Swap paprika for smoked paprika and finish with a pat of compound herb butter for a smoky-herb version.
Use panko instead of plain flour for extra crunch if you prefer a crisper exterior.
Turn this into tacos: fold the bites into warm tortillas with cabbage slaw and a drizzle of aioli.
Make it Mediterranean by topping with chopped tomatoes, olives, and a sprinkle of feta. For a complementary chicken idea, check out garlic butter chicken bites and creamy pasta which uses many of the same flavors.

Delicious Ways to Serve Them

Plate these fish bites on a rustic wooden board, scattering lemon wedges and a small bowl of the garlic aioli. They shine alongside a crisp green salad with a vinaigrette, buttery roasted potatoes, or a pile of herby couscous. For a lively party spread, arrange them on skewers and offer dipping sauces so guests can graze. I love serving them with a chilled glass of Sauvignon Blanc or a citrusy lager; the acidity and bubbles cut through the butter beautifully.

Keeping Leftovers Tasty

Refrigeration: Store cooled fish bites in an airtight container for up to 2 days. Keep the aioli in a separate container to preserve texture and freshness.
Freezing: I do not recommend freezing after frying, as the texture of the crust will degrade. If you must, freeze raw, floured pieces on a tray, then transfer to a freezer bag for up to 1 month; thaw fully before cooking.
Reheating: Reheat gently in a preheated oven at 350 F on a wire rack for 7 to 10 minutes to help restore crispness. Avoid microwaving, which makes them soggy.

Got Questions? Answers Here

Q: Can I use frozen fish?
A: Yes. Thaw fully in the refrigerator and pat dry before proceeding. Excess moisture will prevent proper browning.

Q: Is there a non-mayo option for the aioli?
A: Absolutely. Substitute plain Greek yogurt or blended silken tofu for a lighter, tangy aioli. Adjust lemon and salt to taste.

Q: Can I make the aioli ahead of time?
A: Yes. The aioli actually benefits from a short rest. Make it up to 24 hours ahead and refrigerate in a sealed container, then bring it to cool room temperature before serving for the best flavor lift.

Q: What’s the best fish to use for this?
A: I prefer cod or haddock for their flakiness and mild flavor, but tilapia and pollock work well too. Choose a firm, fresh fillet for best results.
