Ingredients You’ll Need
For The Cod
- 1.5 pounds cod fillets, patted dry (4 pieces, about 6 ounces each)
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1/2 teaspoon smoked paprika (optional but delicious)
- 2 tablespoons olive oil
For The Garlic Butter
- 4 tablespoons unsalted butter
- 4 large garlic cloves, finely minced
- 1/4 teaspoon red pepper flakes (optional heat)
- Zest and juice of 1/2 lemon
- 2 tablespoons chopped fresh parsley (plus more for garnish)
For The Zucchini Noodles
- 4 medium zucchinis, spiralized (or buy pre-spiralized)
- 1 tablespoon olive oil
- 1/2 teaspoon kosher salt
Step-By-Step: From Pan To Plate In 20
- Season the cod: Pat it super dry. Sprinkle with salt, pepper, and smoked paprika.
- Sear the fish: Heat 2 tablespoons olive oil in a large nonstick or stainless skillet over medium-high. Add cod and cook 3–4 minutes per side until opaque and flaky. Transfer to a plate and tent with foil.
- Make garlic butter: Drop heat to medium. Add butter to the same pan. Stir in garlic and red pepper flakes; cook 30–45 seconds until fragrant (don’t brown it). Add lemon zest and juice; swirl. Stir in parsley.
- Sauté zoodles: In a second pan (or wipe the first if roomy), heat 1 tablespoon olive oil over medium-high. Add zucchini noodles and salt. Toss 2–3 minutes until just tender-crisp. Drain off any excess liquid so the sauce won’t get watery.
- Bring it together: Add cod back to the garlic butter pan. Spoon sauce over the fish. Serve cod atop zoodles, drizzling every last drop of sauce. Finish with extra parsley and a wedge of lemon.
Pro Tips You’ll Actually Use
- Dry fish = better sear. Moisture kills browning. Paper towels are your friend.
- Don’t overcook cod. It turns from perfect to cottony fast. Pull when it flakes easily.
- Keep zoodles al dente. Stop cooking the second they soften. Soggy zoodles are a no.
- Want extra richness? Whisk in a tablespoon of cold butter at the end (cheffy move, worth it).
Flavor Twists If You’re Feeling Fancy
Lemony Caper Upgrade
Add 1 tablespoon drained capers with the lemon juice. Briny pops meet buttery sauce—chef’s kiss.
Tomato-Basil Vibes
Toss in 1 cup halved cherry tomatoes with the garlic; cook 1–2 minutes. Swap parsley for basil.
White Wine Splash
Deglaze the pan with 1/4 cup dry white wine after the garlic. Reduce by half, then add butter and lemon.
What To Serve Alongside
You don’t need much, but sidekicks never hurt.
- Crispy roasted potatoes if you want some carbs.
- Simple green salad with a sharp vinaigrette to balance the butter.
- Grilled asparagus with a squeeze of lemon.
Make-Ahead And Leftovers
Prep Smart
- Spiralize zucchini up to 1 day ahead. Store with a paper towel in a sealed container.
- Mix minced garlic, lemon zest, and parsley earlier to speed things up.
Reheat Without Ruining
- Warm cod gently in a covered skillet over low heat with a splash of water or broth—2–3 minutes.
- Quickly re-flash zoodles in a hot pan 30–60 seconds. Don’t microwave them into oblivion.

Common Mistakes (So You Don’t Make Them)
- Overcrowding the pan: Fish steams, doesn’t sear. Use a big skillet or cook in batches.
- Letting garlic brown: Bitter city. Keep heat moderate during the sauce step.
- Salting zoodles too early: They’ll weep like a soap opera. Salt as you sauté, not before.
FAQ
Can I use frozen cod?
Absolutely. Thaw it in the fridge overnight, then pat extremely dry. Frozen fillets can hold extra water, so take the drying step seriously for a good sear.
What fish can I substitute for cod?
Haddock, pollock, halibut, or tilapia all work. Choose thicker fillets if you want a meatier bite; go thinner if you prefer quick-cooking and extra saucy.
Do I need a spiralizer for the zucchini?
Nope. Use a julienne peeler or a mandoline set thin. Worst case, slice into thin ribbons—still twirlable, still tasty.
How do I keep zucchini noodles from getting soggy?
Cook them fast over medium-high heat, then drain any liquid. Avoid salting ahead of time. If they release tons of water, toss them in a hot dry pan for 30 seconds to steam off moisture.
Can I make it dairy-free?
Yes—swap butter for olive oil or a plant-based butter. Add a splash of vegetable broth for extra body, and finish with more lemon and herbs for brightness.
Is this recipe keto-friendly?
Yep. With about 5 net carbs per serving, it fits most low-carb plans. Adjust butter or oil to hit your macro goals, IMO.
Final Bite
Garlic butter cod with zucchini noodles checks every box: fast, flavorful, and weeknight-proof. You’ll get silky sauce, flaky fish, and veggie noodles that don’t feel like a compromise. Make it once and it’ll slide right into your regular rotation—no nagging required. Now go sear like you mean it.
