Mustard Free Lemon Butter Cod
Flaky, golden-seared cod bathed in a bright, nutty lemon butter sauce is the kind of weeknight dinner that feels far more impressive than the effort it takes. The sauce comes together right in the same skillet — browned butter, fresh lemon juice, zest, scallion tops, and parsley — creating layers of flavor that are rich without being heavy. For anyone navigating a mustard-free kitchen, this recipe is a genuine relief: every ingredient is clean and straightforward, with zero hidden condiments or spice blends that might sneak in an unwanted allergen. Garlic-infused oil does the heavy lifting on aromatics, so the fish picks up a subtle savory depth before the sauce even hits the pan. Getting a proper sear is the real secret here — patting the fillets completely dry and letting them cook undisturbed gives you that gorgeous golden crust that makes the whole dish. A squeeze of lemon wedge at the table ties everything together and keeps each bite tasting fresh and vibrant. This is the kind of simple, elegant fish dish you'll want on repeat.
