Garlic Butter Cod Strips with Sweet Chili Lime Sauce
My first pan-seared cod looked halfway between a fish stick and a science experiment. I had left moisture on the fish, and the pan was not hot enough, so the coating steamed instead of turning crisp. I ruined that batch of butter cod strips before I learned to pat the cod dry and heat the skillet properly.
I tested this garlic butter cod strips with sweet chili lime sauce recipe three times, changing only the coating. The most important variable in this recipe is the cornstarch coating: a thin dusting creates a crisp edge, while a thick layer turns pasty. Dry fish lets surface moisture escape into the hot pan instead of softening the crust. The sauce came together on the first try, thankfully.
Each cod strip stays flaky and moist inside, with enough crust to hold the garlic butter before you dip it into the sweet chili lime sauce. The scary moment comes when a strip seems stuck at first; don’t yank it up. Once the crust sets, it releases cleanly. This quick fish recipe takes about 25 minutes, with the sauce ready while the cod cooks.

- Ready in about 25 minutes: The cod cooks quickly, and the sauce takes about five minutes to mix.
- Lightly crisp: The thin coating adds texture without covering the garlic butter flavor.
- One sauce, two uses: Dip the cod strips or spoon the sauce over rice.
- Easy to manage: Smaller pieces cook more evenly than a whole fillet.
Key Ingredients
Cod fillets (1½ pounds / 680g). Cut the cod fillets into strips; the mild, firm flesh stays flaky while letting the butter and sauce lead. Haddock swaps evenly, while denser halibut may need more time.
Cornstarch (⅓ cup / 40g). Cornstarch forms a dry, porous surface that crisps quickly. Too much traps moisture and turns gummy.
Unsalted butter (4 tablespoons / 56g). Butter carries the garlic flavor and coats the fish. Unsalted butter keeps the seasoning easy to control.
Garlic (5 cloves, minced). Use 4 cloves for the butter and 1 for the sauce. Fresh garlic tastes fuller than jarred garlic.
Thai sweet chili sauce (⅓ cup / 80ml). This sweet chili base supplies sweetness and mild heat. Check the label if gluten-free.
Lime juice and zest (3 tablespoons juice, 1 teaspoon zest). Lime cuts through the butter; reserve 2 tablespoons of lime juice for the sauce and 1 tablespoon for the fish.
Sauce seasonings. Add 1 tablespoon honey, 1 teaspoon fish sauce (or 1 teaspoon soy sauce), and ¼ teaspoon red pepper flakes. For the coating, use 1 teaspoon smoked paprika, 1 teaspoon garlic powder, 1 teaspoon salt, and ½ teaspoon pepper.
Ingredient Note: Measure the coating and sauce ingredients before cooking. The cod moves quickly once it reaches the skillet.
Equipment You’ll Need
- Large non-stick or stainless skillet — cast iron works too, but preheat it a full 2 minutes longer since it holds heat differently.
- Fish spatula or thin metal spatula — a thin edge slides under delicate strips without tearing them. A regular spatula works if you’re gentle.
- Microplane or fine grater — for the lime zest. A regular box grater’s fine side works as a substitute.
- Small whisk or fork — for the sauce. No special tool needed.
Controlling the Cornstarch Coating for a Crisp Crust
I tested three butter cod versions side by side, changing only the cornstarch coating while keeping the cod strips, pan, heat, butter, and cook time the same. This test showed how a small coating change affects the finished texture.
The first batch had no coating: the strips stayed tender and buttery but had no crisp edge. The second used a light dusting, about 1 tablespoon per strip, with the excess shaken off. It produced a thin crust that let the garlic and butter shine. The third used a heavy coating, pressed on without shaking. Clumps held moisture, formed a thick gelatinized layer, and turned pasty. The light coating was the clear winner for this butter cod recipe. A bowl makes shaking off excess simple; season the cornstarch evenly, and use oil only if your skillet needs extra protection from sticking.
The takeaway: Dust the cod strips lightly until you can still see the fish beneath the coating. If the surface looks opaque, remove more excess before cooking. The sweet chili sauce adds moisture after searing, so serve it alongside rather than covering the crust too early.
How to Make Garlic Butter Cod Strips with Sweet Chili Lime Sauce
Before you start: Pat the cod fillets dry, measure the coating and sauce ingredients, and set out a clean plate. The fish cooks quickly, so preparation keeps the skillet from becoming a juggling act.
Step 1 — Cut and season the cod
Cut 1½ pounds of cod into 1-inch strips, following the natural seams so the pieces hold together. In a shallow dish or bowl, combine ⅓ cup cornstarch, 1 teaspoon smoked paprika, 1 teaspoon garlic powder, 1 teaspoon salt, and ½ teaspoon pepper. Season the fish evenly; the dry mixture gives the surface flavor before it hits the butter.
Step 2 — Dust the strips lightly
Press each strip gently into the seasoned cornstarch, then shake off the excess until you can still see the fish beneath it. Set the coated strips in a single layer while the skillet heats. A thin layer dries and crisps quickly; a thick one stays pasty.
Step 3 — Melt the butter and bloom the garlic
Heat a large skillet over medium heat, add 4 tablespoons unsalted butter, and wait until it foams lightly. Add 4 minced garlic cloves and stir for 30 seconds, just until fragrant and pale gold. Garlic releases its aroma into the warm butter, but it becomes bitter quickly if it browns.
Step 4 — Sear the cod strips
Arrange the cod strips in one layer with space between them. Cook for 2 to 3 minutes per side. If a piece seems stuck, wait 30 seconds rather than forcing it; a set crust releases more cleanly. Turn when golden, then cook until the center reaches 145°F and the cod flakes easily.
Step 5 — Baste and finish with lime
Spoon the garlic butter over the strips for the final 30 seconds. Remove the skillet from the heat, add 1 tablespoon lime juice and 1 teaspoon zest, and rest the fish for 1 minute. Adding lime off heat keeps its fresh acidity from tasting dull.
Step 6 — Make the sauce
While the cooked cod rests, whisk ⅓ cup sweet chili sauce, 2 tablespoons lime juice, 1 minced garlic clove, 1 tablespoon honey, 1 teaspoon fish sauce, and ¼ teaspoon red pepper flakes. The sweet chili and chili lime flavors balance the rich butter.
Step 7 — Plate and serve
Transfer the strips to a plate, spoon over any remaining garlic butter, and scatter with chopped parsley. Serve immediately with the sweet chili lime sauce for dipping or drizzling. Pan searing gives the best crust; baking is easier but less crisp.
Pro Tips for Garlic Butter Cod Strips
Tip 1: Cook the cod strips in batches if needed. Space between pieces lets hot butter sear the fish instead of trapping steam.
Tip 2: Stir the garlic for exactly 30 seconds, then lower the heat if it starts browning. Burnt garlic can overpower the garlic butter.
Tip 3: Taste the sweet chili sauce before serving. Add lime juice in 1-teaspoon additions if the sauce tastes too sweet.
Variations and Substitutions
Dietary Variations:
- Gluten-free: The recipe is gluten-free if your sweet chili sauce and soy sauce labels confirm no wheat ingredients.
- Dairy-free: Replace the butter with refined coconut oil or dairy-free butter; the flavor will be less rich.
Flavor Variations:
- Spicier: Add ½ teaspoon sriracha to the chili sauce or increase the red pepper flakes.
Ingredient Substitutions:
- Use bottled lime juice at 1½ times the fresh amount.
- Replace 1 teaspoon fish sauce with 1 teaspoon soy sauce, then reduce added salt slightly.
- For sweet chili sauce, mix 3 tablespoons apricot preserves, 1 tablespoon rice vinegar, and red pepper flakes.

Troubleshooting
Why did my cod fall apart when I flipped it?
The skillet may not have been hot enough, or the crust needed more time. Wait 30 seconds, then slide a thin spatula underneath the cod strips.
Why is my crust soggy?
Crowding traps steam and softens the crust. Cook the strips in batches and keep them uncovered until serving.
Why does the sweet chili sauce taste too sweet?
Stir in lime juice 1 teaspoon at a time until the flavor balances.
Storage and Make-Ahead
Refrigerate cooked cod within 2 hours in an airtight container for up to 2 days. Keep the sauce separate for up to 5 days. Freeze cod strips for 1 month; the crust will soften as trapped steam moves into the coating.
To reheat, use a 300°F oven for 8–10 minutes. Skip the microwave, which makes the butter cod coating rubbery. Make the sauce up to 5 days ahead.
Frequently Asked Questions
What fish can replace cod? Haddock is closest. Halibut works too, but thicker fillets may need 1 extra minute per side.
Can I bake this cod recipe? Yes. Bake at 425°F for 10–12 minutes, flipping once. It is easier than pan seared cod, but the crust will be less crisp.
Is sweet chili sauce spicy? Usually, it is mild and sweet, with light chili heat. Add red pepper flakes for more spice.
Can I make the sauce ahead? Yes. Refrigerate it in a sealed container for up to 5 days.
How do I know the cod is cooked? The center should reach 145°F and flake easily. One-inch pieces usually take about 5 minutes total.
Can I air fry the cod? Yes. Air fry at 400°F for 7–9 minutes, flipping once. Serve with rice and sauce.

Garlic Butter Cod Strips with Sweet Chili Lime Sauce
Ingredients
For the Cod Strips:
- 11/2 lb cod fillets, cut into 1-inch strips
- 1/3 cup cornstarch
- 1 tsp smoked paprika
- 1/2 tsp garlic powder
- 1/2 tsp kosher salt
- 1/4 tsp black pepper
- 4 tbsp unsalted butter
- 4 clove garlic, minced
- 1 tbsp fresh lime juice
- 1 tsp lime zest
- 2 tbsp chopped fresh parsley
For the Sweet Chili Lime Sauce:
- 1/3 cup (80ml) Thai sweet chili sauce
- 2 tbsp fresh lime juice
- 1 tsp fish sauce (optional)
- 1 clove garlic, minced
- 1/2 tsp honey
- Pinch red pepper flakes
Instructions
- Slice the cod fillets into 1-inch-wide strips and pat dry thoroughly with paper towels.
- In a shallow dish, whisk together the cornstarch, smoked paprika, garlic powder, salt, and pepper.
- Dredge each cod strip in the seasoned cornstarch, then shake off the excess until only a faint coating remains.
- Melt the butter in a large skillet over medium heat. Add the minced garlic and stir for about 30 seconds, until fragrant and pale gold.
- Lay the cod strips into the garlic butter in a single layer, leaving space between each piece. Sear 2–3 minutes per side, until golden and opaque throughout.
- Spoon the remaining butter over the strips for the last 30 seconds of cooking, then remove from heat. Squeeze fresh lime juice over the top and sprinkle with lime zest. Let rest 1 minute in the pan.
- While the cod rests, whisk together the sweet chili sauce, lime juice, minced garlic, fish sauce, honey, and red pepper flakes in a small bowl. Taste and adjust with extra lime or honey as needed.
- Transfer the cod strips to a serving plate, spoon any remaining pan butter over the top, and garnish with chopped parsley. Serve with the sweet chili lime sauce alongside.
Notes
- Pat the cod dry twice — once before cutting and once after — to keep the cornstarch crust from turning gummy.
- Use a light hand with the cornstarch dredge; shake off the excess until the coating is barely visible for the crispest result.
- Cook in two batches if your skillet can't fit all the strips with space between them — crowding softens the crust.
- The sauce can be made up to 5 days ahead and stored in the refrigerator.
- Leftover cod strips reheat best in a 300°F oven for 8–10 minutes; the microwave will make the crust rubbery.
- If using frozen cod, thaw completely and pat very dry before cutting — frozen fish holds significantly more moisture.
