Ingredients
- Cod fillets: 4 fillets (about 5–6 ounces each), skinless
- Fresh green beans: 12 ounces, trimmed
- Unsalted butter: 4 tablespoons, divided
- Olive oil: 1 tablespoon
- Garlic: 3–4 cloves, minced
- Lemon: 1 large, zested and juiced (about 2–3 tablespoons juice)
- Chicken or vegetable broth: 1/3 cup
- Fresh parsley: 2 tablespoons, chopped
- Crushed red pepper flakes: A pinch (optional)
- Salt and black pepper: To taste
- Lemon wedges: For serving
Step-by-Step Instructions
- Prep the cod and beans. Pat the cod fillets dry with paper towels.
Season both sides with salt and black pepper. Trim the ends off the green beans and set aside.
- Blanch the beans (optional but recommended). Bring a small pot of salted water to a boil. Cook green beans for 2–3 minutes until bright green and slightly tender.
Drain and rinse under cold water to stop cooking. This step helps them cook evenly later.
- Heat the pan. Place a large skillet over medium heat. Add 1 tablespoon olive oil and 1 tablespoon butter.
When the butter foams, swirl to coat.
- Sear the cod. Add the cod to the skillet. Cook 3–4 minutes on the first side without moving it, until lightly golden and the edges turn opaque. Flip carefully and cook another 2–3 minutes, depending on thickness, until the fish flakes easily.
Transfer to a plate and tent loosely with foil.
- Sauté the garlic. Reduce heat to medium-low. Add another 1 tablespoon butter to the skillet. Stir in the minced garlic and cook 30–45 seconds, just until fragrant.
Don’t let it brown.
- Build the sauce. Pour in the broth, scraping up any browned bits from the pan. Simmer for 1–2 minutes to reduce slightly. Stir in the lemon juice and a pinch of red pepper flakes, if using.
- Add the green beans. Toss the blanched green beans into the sauce.
Cook 2–3 minutes, stirring, until they’re coated and warmed through. Season with a pinch of salt and pepper.
- Finish with butter and zest. Turn off the heat. Stir in the remaining 2 tablespoons butter and the lemon zest until the sauce looks glossy.
Add the chopped parsley.
- Return the cod to the pan. Nestle the fillets back into the skillet, spooning sauce over the top. Let it sit for 30–60 seconds to warm through. Taste and adjust seasoning.
- Serve. Plate the cod with the green beans and drizzle extra sauce over everything.
Serve with lemon wedges.
Storage Instructions
Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat with a splash of water or broth to keep the fish moist. Avoid microwaving on high, which can toughen the cod.
If freezing, store the cooked cod separately from the beans and sauce. Thaw in the refrigerator overnight and reheat slowly for the best texture.
Benefits of This Recipe
- Quick and simple: From prep to plate in around 25–30 minutes.
- Balanced meal: Protein, vegetables, and healthy fats in one pan.
- Light but satisfying: Lemon and garlic keep the dish bright, while butter adds richness.
- Flexible: Works with other white fish and different veggies.
- Minimal cleanup: One skillet does it all.
Common Mistakes to Avoid
- Skipping the pat-dry step: Wet fish won’t sear well and can steam instead of brown.
- Overcooking the cod: It cooks fast. Pull it when it flakes easily and looks opaque.
- Burning the garlic: Keep the heat moderate and add garlic after searing the fish.
- Using too much lemon juice early: Add it after the broth reduces so the sauce doesn’t taste harsh or thin.
- Neglecting seasoning: Taste at the end and adjust salt, pepper, and lemon for balance.
Recipe Variations
- Herb butter twist: Swap parsley for dill, chives, or basil.
Add a spoonful of capers for briny pop.
- Add potatoes: Parboil baby potatoes and crisp them in the pan before the beans for a heartier meal.
- Creamy lemon sauce: Stir in 2 tablespoons heavy cream at the end for extra richness.
- Spice it up: Add more red pepper flakes or a dash of smoked paprika when searing the cod.
- Different fish: Try halibut, haddock, pollock, or tilapia. Adjust cook time based on thickness.
- Sheet pan method: Roast green beans at 425°F (220°C) with oil, salt, and pepper for 12–15 minutes. Pan-sear the cod and spoon the lemon-butter sauce over at the end.
- Garlic lemon panko: Toast panko in butter with garlic and lemon zest.
Sprinkle over the fish for crunch.
FAQ
How do I know when cod is cooked?
Cod is done when it flakes easily with a fork, looks opaque, and reaches an internal temperature of about 145°F (63°C). It should feel tender, not rubbery. If it still looks glassy in the center, give it another 30–60 seconds.
Can I use frozen cod?
Yes.
Thaw it completely in the refrigerator and pat it very dry before cooking. Frozen fillets can release extra moisture, so thorough drying is key to getting a good sear.
What can I substitute for green beans?
Asparagus, broccolini, snap peas, or thinly sliced zucchini work well. Adjust cooking time so the vegetables stay crisp-tender.
Do I need to blanch the green beans?
It’s optional, but it helps keep the beans vibrant and evenly cooked.
If skipping, simply sauté them a bit longer in the sauce until tender.
Which pan works best?
A large nonstick or well-seasoned stainless-steel skillet is ideal. If using cast iron, keep the heat moderate and add a touch more oil to prevent sticking.
Can I make this dairy-free?
Use olive oil or a dairy-free butter alternative. The flavor will be lighter, so add extra lemon zest and fresh herbs to keep it bright.
How can I make it more filling?
Serve with rice, quinoa, mashed potatoes, or crusty bread to soak up the sauce.
A simple side salad rounds out the plate nicely.
In Conclusion
Lemon Garlic Butter Cod with Green Beans brings clean, fresh flavors together in a simple skillet dinner. It’s quick, weeknight-friendly, and versatile enough to adapt to what you have on hand.
