Ingredients for Slow Cooker Herb-Crusted Cod with Lemon and Garlic

Instructions

In a small bowl, whisk together olive oil, minced garlic, lemon zest and juice, parsley, dill, dried oregano, salt, black pepper, and crushed red pepper flakes (if using) to create the herb-lemon garlic crust mixture.
Arrange the sliced onion, cherry tomatoes, and bell peppers evenly in the bottom of the slow cooker to form a flavorful vegetable bed.
Pour the vegetable broth over the vegetables in the slow cooker.
Pat cod fillets dry with paper towels. Evenly coat each fillet on all sides with the herb-lemon garlic mixture.
Place the coated cod fillets carefully on top of the vegetable bed in the slow cooker.
Cover and cook on LOW for 2 to 2 1/2 hours, or until the cod is opaque and flakes easily with a fork. Avoid overcooking to maintain tender, moist fish. Verify the thickest part reaches 145 F (63 C); cooking time varies by cooker and fillet thickness.
Using a wide spatula, gently lift the cod fillets from the slow cooker and arrange on serving plates. Spoon the cooked vegetables and pan juices over or alongside the fish.
Serve immediately with steamed greens, quinoa, or gluten-free crusty bread for a complete meal.
Store leftovers in an airtight container in the refrigerator for up to 3 days or freeze for up to 1 month.
